Description

[0001] The present application claims priority on the basis of Chinese Patent Application No. 201910254174.3, filed with the National Intellectual Property Office of China on March 30, 2019 and entitled "COMMUNICATION METHOD AND COMMUNICATIONS APPARATUS", which is incorporated herein by reference in its entirety.

Technical field

[0002] This application relates to the field of communication technologies and, in particular, to a communication method and communication equipment.

State of the art

[0003] Dynamic time division duplex (TDD) can also be referred to as flexible duplexing or duplexing flexibility and means that uplink and downlink resources can be adaptively allocated based on the allocation of uplink and downlink services, and hence the utilization of system resources is effectively improved.

[0004] Typically, dynamic TDD has a cross-link interference (CLI) problem. Crosstalk can also be referred to as crosstalk interference, i.e. interference between links in different directions. As shown in FIG. 1a, on the one hand, sending the uplink of the second terminal or the third terminal served by the second network device causes a CLI to receive the downlink of the first terminal served by the first network device, and such CLIs may be referred to as inter-terminal interference (UE-to -UE); on the other hand, the downlink sending of the first network device causes a CLI to be received on the uplink of the second network device, and such CLIs may be referred to as inter-base station interference (gNB-to-gNB).

[0005] Referring to FIG. 1b, in an ultra-dense network having a plurality of network devices, a wireless backhaul may exist between different network devices. When an access link between a network device and a terminal device coexists with a transit link between network devices, the above-mentioned CLIs also occur.

[0006] Unlike the previous interference of co-directional links, dynamic TDD has the following features: strong interference, large influence, rapid direction change, no established mechanism for solving the problem, and the like. Therefore, there is an urgent need to provide a method that allows the system to know the level of crosstalk.

The essence of the invention

[0007] Embodiments of this application provide a communication method and communication equipment for measuring crosstalk.

[0008] To solve the above problem in the embodiments of the present application, the following technical solutions are used.

[0009] According to a first aspect, an embodiment of this application provides a communication method. The method may be performed by the first terminal or by a component (eg, a chip system) in the first terminal. The method includes: The first terminal receives at least one first sounding reference signal (SRS) from at least one second terminal, obtains information about the measurement result of at least one second terminal based on at least one first SRS , and sends information about one or more measurement results to a network device. The measurement result indicates the signal strength of the first SRS from the second terminal, the first SRS is used to measure the CLI, and the first SRS occupies the first resource.

[0010] The communication method presented in this application can be used in a communication system in which CLIs exist. For example, the communication system is a flexible duplex system or an integrated access and backhaul system (Integrated Access and Backhaul, IAB). Alternatively, the method can be used in a remote interference management (RIM) system. For example, the method can be used in the communication systems shown in FIG. 1a and fig. 1b.

[0011] According to the communication method provided in this embodiment of this application, after the second terminal sends the first SRS, if the first terminal can obtain by monitoring the first SRS of the second terminal, the first terminal can measure the signal strength of the first SRS and obtain the measurement result of the first SRS. In addition, the first terminal can further report the measurement result to the network device, so that the network device can receive the measurement results of various second terminals. Thus, subsequently, the network device can learn, based on one or more measurement results, the CLI levels caused by different second terminals for the first terminal, and perform some CLI reduction operations.

[0012] In addition, when the network device does not receive the measurement result, the network device can learn, based on the second indication information corresponding to the measurement result, the specific second terminal that causes interference to the first terminal. For example, when the first terminal measures a specific first SRS and returns the second indication information of the first SRS to the network device, the network device may determine the transmitting end of the transmission of the first SRS, where the second indication information includes, but is not limited to, at least one of the first SRS sequence, set the sequences of the first SRS or the resource identifier of the first SRS. For example, the first terminal measures a particular first SRS and returns a resource identifier of the first SRS to the network device. Therefore, the network device can know the specific second terminal that sends the first SRS via the resource indicated by the resource identifier, and the network device can determine the interferer that causes the CLI for the first terminal.

[0013] In an exemplary embodiment, information about one or more measurement results includes indication information of one or more measurement results and/or second indication information, and the second indication information is indication information of the second terminal corresponding to one or more measurement results, respectively.

[0014] In an exemplary embodiment, the method further includes: The first terminal receives the first indication information, where the first indication information indicates that the first terminal should send the N largest measurements as a result of measurements of at least one second terminal or the N smallest measurements as a result of measurement of at least one second terminal, and N is an integer greater than or equal to 1.

[0015] Accordingly, that the first terminal sends one or more measurement information to the network device includes: The first terminal sends N measurement results to the network device based on the first indication information.

[0016] In a possible implementation, the method further includes: The first terminal receives the first indication information, where the first indication information indicates that the first terminal should send the second indication information corresponding to the N largest measurement results from the measurement of at least one second terminal, or second indication information corresponding respectively to the N smallest measurement results from the measurement of at least one second terminal, and N is an integer greater than or equal to 1.

[0017] The second indication information indicates the second terminal corresponding to the measurement result.

[0018] Accordingly, that the first terminal sends information about one or more measurement results to the network device includes: The first terminal sends to the network device, based on the first indication information, second indication information corresponding to N measurement results.

[0019] In an exemplary embodiment, the method further includes: The first terminal receives the first indication information, where the first indication information indicates that the first terminal should send the N largest measurement results from the measurement of at least one second terminal, and the second indication information, respectively corresponding to the N largest measurement results, and N is an integer greater than or equal to 1.

[0020] Accordingly, that the first terminal sends information about one or more measurement results to the network device includes: The first terminal sends to the network device, based on the first indication information, N measurement results and second indication information corresponding to the N measurement results, respectively .

[0021] In an exemplary embodiment, the method further includes: The first terminal obtains the first indication information, where the first indication information indicates that the first terminal should send the N smallest measurement results from the measurement of at least one second terminal, and the second indication information, respectively corresponding to the N smallest measurement results, and N is an integer greater than or equal to 1.

[0022] Accordingly, that the first terminal sends information about one or more measurement results to the network device includes: The first terminal sends to the network device, based on the first indication information, the N smallest measurement results and the second indication information corresponding to the N results, respectively. measurements.

[0023] Thus, when the measurement result of a particular second terminal is larger, the level of CLIs caused by the second terminal for the first terminal is generally higher. The network device can approximately know the CLI status between the first terminal and the other terminal based on the measurement result with the highest CLI level to perform some CLI reduction operations, thereby reducing the CLI between the first terminal and the other terminal. It can be recognized that only a part of the measurement result is reported, so that the signaling overhead for reporting the measurement result is reduced.

[0024] In an exemplary embodiment, the method further includes: The first terminal receives the first indication information, where the first indication information indicates that the first terminal should send J measurements that are the measurement result of at least one second terminal and that are greater than or equal to a first threshold value, and/or second indication information corresponding to J measurement results, and J is a positive integer.

[0025] Accordingly, that the first terminal sends information about one or more measurement results to the network device includes: The first terminal sends to the network device, based on the first indication information J, the measurement results that are the measurement result of at least one the second terminal and which are greater than or equal to the first threshold value, and/or second indication information corresponding to the J measurement results.

[0026] Thus, only a portion of the measurement result is reported, so that the signaling overhead for reporting the measurement result can be reduced.

[0027] In an exemplary embodiment, the method further includes: The first terminal obtains first indication information, where the first indication information indicates that the first terminal should send W measurement results that are the measurement result of at least one second terminal and that are less than or equal to a second threshold value, and/or second indication information corresponding to W measurement results, and W is a positive integer.

[0028] Accordingly, that the first terminal sends information about one or more measurement results to the network device includes: The first terminal sends to the network device, based on the first indication information W of the measurement results that are the measurement result of at least one of the second terminal and which are less than or equal to the second threshold value, and/or second indication information corresponding to W measurement results.

[0029] In a possible implementation, that the first terminal sends information about one or more measurements to the network device includes:

[0030] The first terminal sends to the network device at the first time the first measurement result and/or the second indication information corresponding to the first measurement result, and sends to the network device at the second time the second measurement result and/or the second indication information corresponding to the second result measurement, wherein the interval between the first time and the second time is a predetermined time period. The difference between the second measurement result and the first measurement result is greater than or equal to the preset difference.

[0031] In other words, only when the measurement result at the second time point is very different from the measurement result at the first time point, the first terminal reports the measurement result, which is the measurement result at the second time point and is characteristic of the same second terminal. According to the above method, for the second terminal, the first SRS may be measured a plurality of times in order to improve the accuracy of the measurement result of the first SRS of the second terminal. In addition, measurement results with similar values usually indicate that the position, signal quality, etc. the second terminal does not change or changes slightly. In this case, the obtained measurement result of the first SRS of the second terminal may be redundant information, and the network device may not need redundant information to make a decision. Therefore, in this embodiment of this application, the first terminal reports only the measurement result, which is the measurement result at the second time point and which is very different from the measurement result at the first time point. Thus, it is possible to prevent the first terminal from reporting an excessive measurement result with the same value, and the signaling overhead is reduced.

[0032] In an exemplary embodiment, the method further includes: The first terminal receives configuration information, where the configuration information indicates at least one of the following:

reports the second indication information of the first SRS, where the second indication information of the first SRS includes one or more of the first SRS resource indication information or the first SRS sequence.

[0033] Reporting the second indication information of the first SRS includes: reporting the second indication information with a measurement result in one or more measurement results that have a one-to-one correspondence with the second indication information. In other words, when the measurement result is reported, the second indication information corresponding to the measurement result is also reported.

[0034] Thus, when two measurement results are reported, some other information is also reported, so that when receiving the measurement results, the network device becomes aware of the specific terminals from which the interference corresponding to the measurement results is emitted.

[0035] Of course, reporting the second indication information of the first SRS includes: separately reporting the second indication information and one or more measurement results. In other words, the measurement result may be transmitted independently, or the second indication information may be transmitted independently.

[0036] In an exemplary embodiment, the method further includes: The first terminal sends the first capability information to the network device, where the first capability information indicates CLI measurement capability information, and the first capability information includes at least one of the following: the number of first SRSs that can be tracked by the first terminal per unit of time, whether the first terminal can track consecutive symbols, the maximum number of symbols that can be tracked by the first terminal per unit of time, or the maximum number of consecutive symbols that can be tracked by the first terminal per unit of time.

[0037] Thus, it can be ensured that the first SRS from the second terminal matches the capabilities of the first terminal, that is, the first terminal can measure the first SRS without going beyond the capabilities of the first terminal. Increased chance of successful first SRS measurement.

[0038] In an exemplary embodiment, the method further includes: The first terminal reports third capability information, where the third capability information indicates a multiplexing relationship between the second resource and the first resource for receiving the first SRS, the multiplexing relationship includes at least one of multiplexing time division multiplexing or frequency division multiplexing, and the second resource is the resource used for data transmission.

[0039] Thus, when receiving the third capability information and configuring the first resource and the second resource for the terminal, the network device properly performs the resource configuration depending on whether the terminal supports the resource multiplexing relationship to reduce the possibility of collision between the first resource and the second resource .

More precisely, the use of terms such as "example" or "for example" is intended to represent a relative concept in a certain way.

[0144] In addition, in embodiments of this application, "at least one" usually means one or more. "Many" usually means two or more. The term "and/or" describes an association relationship for describing associated objects and represents that there may be three relationships. For example, A and/or B may represent the following cases: Only A exists, both A and B exist, and only B exists, where A and B can be singular or plural. The "/" symbol usually indicates an "or" relationship between associated objects.

[0145] The communication method provided in the embodiments of this application can be used in a communication system in which CLIs exist. For example, the communication system is a flexible duplex system or an integrated access and backhaul system (Integrated Access and Backhaul, IAB). Alternatively, the method can be used in a remote interference management (RIM) system. Fig. 1a is an exemplary communication system architecture to which an embodiment of this application is applicable. The communication system includes a network device and a terminal device. Fig. 1a shows an example of three terminal devices (namely, UE 1 to UE 3) and two network devices (namely, base station 1 and base station 2). The terminal device may be connected to a network device via an air interface to receive a network service. The network device is generally configured to implement a radio physical layer function, resource scheduling and radio resource management, radio access control, a mobility management function, or another function. In this application, any of the first terminal, the second terminal, or the third terminal may be replaced by a network device, namely a first network device, a second network device, or a third network device. The first terminal, second terminal or third terminal in this application is a terminal device.

[0146] In this application, "receiving" includes: pre-configured in the terminal/network device or configured by the network device for the terminal. In this application, "configuration" or "configured" may be "configured by a network device for a terminal using signaling". The signaling may be at least one of RRC signaling, MAC signaling, or physical layer signaling.

[0147] The network device may be a device that has the function of a wireless transceiver, or may be a chip system that is located in the device, or may have another form. A network device includes, but is not limited to: an access point (AP) in a Wi-Fi system, such as a home wireless router, a wireless relay node, a wireless transit node, a transmission and reception point (TRP, or transmission point, TP), eNB, macro base station, micro base station, high frequency base station, new radio eNB eNB, radio network controller (RNC), NodeB (NodeB, NB), base station controller (BSC ), base transceiver station (BTS), home base station (e.g. home evolved NodeB or home NodeB, HNB), baseband unit (BBU), or may be a gNB or transfer point (TRP or TP ) in a 5G system such as NR, or by one antenna panel or a group of antenna panels (including a plurality of antenna panels) of a base station in a 5G system; or may be a network node such as a baseband unit (BBU) or a distributed unit (DU) that constitutes a gNB or transmission point.

[0148] In some deployments, a gNB may include a centralized unit (CU) and a distributed unit (DU). gNB may additionally include a radio frequency module (radio unit, RU). CU implements part of gNB functionality and DU implements part of gNB functionality. For example, the CU implements the functions of the radio resource control (RRC) layer, the packet data convergence protocol (PDCP) layer, and the service discovery application profile (SDAP) layer; and the DU implements the functions of the radio link control (RLC), media access control (MAC), and physical (PHY) layers. The information at the RRC layer is eventually converted to information at the PHY layer or converted from the information at the PHY layer. Therefore, in this architecture, higher layer signaling, such as RRC layer signaling or PHCP layer signaling, can also be considered to originate from a DU or from a DU and a RU. It is understood that the network device may be a CU node, a DU node, or a device including a CU node and a DU node. In addition, the CU may be classified as a network device in the access network (radio access network, RAN) or may be classified as a network device in the core network (core network, CN). It's not limited here.

[0149] The terminal device may be a user equipment that has a wireless transceiver function, or may be a chip system that resides in the user equipment. For example, a terminal device may also be called a station (station, STA), user equipment (user equipment, UE), access terminal, user equipment, subscriber station, mobile station, mobile console, remote station, remote terminal, mobile device, user terminal, wireless communication device, user agent, or user equipment. The terminal device includes, but is not limited to: a mobile phone (mobile phone), a tablet computer (Pad), a computer with a wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal in industrial control, a wireless terminal in self driving, a wireless terminal in transportation safety, a wireless terminal in a smart city, or a sensor device such as a control terminal.

The processor 201 is configured to execute a computer-executable instruction stored in the memory 203 to implement the methods provided in the following embodiments of this application.

[0159] Optionally, the computer-executable instruction in the embodiments of this application may also be referred to as an application program code, instruction, computer program, or other name. This is not specifically limited in the embodiments of the present application.

[0160] At a specific implementation time, in an embodiment, processor 201 may include one or more processors (CPUs), such as CPU 0 and CPU 1 in FIG. 2.

It should be understood that the communication device shown in the drawing is merely an example, and during actual use, the communication device may have more or fewer components than those shown in FIG. 2, or two or more components may be combined, or the communication device may have different component configurations.

[0164] Communication device 200 may be a general purpose device or a dedicated device. The type of communication device 200 is not limited to the embodiments of this application. The network access terminal or device may be a device having a structure similar to that in FIG. 2.

[0165] The following describes the communication method provided in the embodiments of this application with reference to the communication systems shown in FIG. 1a and fig. 1b. In the following, the example in which the network device is a base station is mainly used for description. Here is a single summary, the details are not described below.

[0166] Referring to FIG. 3, the communication method provided in the embodiment of this application includes the following steps.

[0167] S301: The second terminal sends the first SRS to the first terminal.

[0168] Accordingly, the first terminal receives at least one SRS from at least one second terminal. The first SRS is used to measure the CLI, and the first SRS occupies the first resource.

[0169] In this embodiment of this application, the first terminal is usually a terminal that can be interfered with. In this specification, the first terminal may also be referred to as an interfered terminal. The second terminal is the terminal that can invoke the CLI for the first terminal. In this specification, the second terminal may also be referred to as an interfering terminal. In various scenarios, the roles of the first terminal and the second terminal may be reversed. For example, in FIG. 1a, UE 2 and UE 3 send on the uplink. In this case, UE 2 and UE 3 may call the CLI for UE 1. Accordingly, UE 1 may be referred to as the first terminal, and UE 2 and UE 3 may be referred to as the second terminals. In another communication scenario, for example, if UE 1 is sending on the uplink, UE 1 may be referred to as the second terminal and, respectively, UE 2 and UE 3 that may be interfered with by UE 1 sending on the uplink may be referred to as first terminals. Typically, UE 1 and UE 2 may be UEs, respectively, belonging to neighboring cells. However, in some special cases, such as in a full duplex scenario, UE 1 and UE 2 may be UEs belonging to the same cell.

[0170] In this embodiment of this application, the first SRS is the SRS used to measure the CLI. The specific interfering terminal sends the first SRS on the first resource. The interfered terminal monitors the first SRS; and after receiving the first SRS, measures the signal strength of the first SRS to obtain the measurement result of the first SRS. Optionally, the measurement result may be a measurement result of layer 3 (layer 3, L3), namely, the measured signal level of the first SRS is filtered to obtain the measurement result of L3. The filtering may be layer 3 filtering, and the parameter used for layer 3 filtering may be configured. Optionally, the measurement result obtained after the measurement of the first SRS signal level may be the measurement result of layer 1 (layer 1, L1).

[0171] It is easy to understand that different second terminals may send the first SRS, and the first terminal may monitor the first SRS from one or more second terminals and determine the signal strength of the corresponding first SRS. Fig. 3 uses an example in which two second terminals send the first SRS to the first terminal.

[0172] S302: The first terminal obtains measurement result information of at least one second terminal based on the at least one first SRS.

[0173] The measurement result indicates the signal strength of the first SRS from the second terminal.

[0174] It is easy to understand that after receiving the first SRS from one or more second terminals through tracking, the first terminal can measure the signal strength of each first SRS to obtain a measurement result of each second terminal. The measurement result of the specific second terminal indicates the level of the first SRS signal from the second terminal, and may further indicate the level of CLIs caused by the second terminal for the first terminal. In addition, a higher level of the first SRS signal from the second terminal, that is, a larger value of the measurement result, indicates a higher degree of CLI caused by the second terminal for the first terminal. Optionally, for the first terminal to measure the signal strength of the first SRS, the first terminal may measure the RSRP of the first SRS and use the RSRP of the first SRS as the measurement of the first SRS. Alternatively, the first terminal measures the RSSI of the first SRS and uses the RSSI of the first SRS as the measurement result of the first SRS. Alternatively, the first terminal may use both the RSRP and the RSSI of the first SRS as the measurement result of the first SRS. Alternatively, the first terminal may use another indicator as the measurement result of the first SRS. The indicators are not listed individually here. The indicator that is specifically used by the first terminal as a measurement result may be indicated by the network device using the configuration information. Alternatively, the first terminal determines, in accordance with a preconfigured rule in the first terminal, a specific indicator to be used as the measurement result. Details of a specific indicator that is used by the first terminal as a measurement result are given in the following description.

[0175] Optionally, the measurement result may be obtained by the first terminal by performing inference, filtering, or calculation on the measurement sample of the first SRS in the first time period. In particular, the result of the measurement may be an average of the measurement samples of the first SRS in the first time period, for example, the average of the values obtained by weighting the measurement samples of the first SRS in the first time period based on various parameters. The first time period that is set to measure the first SRS may be configured.

[0176] Alternatively, the measurement result may be obtained by the first terminal by performing inference, filtering, or calculation on the measurement sample of the first SRS in the second time period. In particular, the measurement result may be a proportion of the number of measurement samples that are in the measurement samples of the first SRS in the second time period and that exceed the fourth threshold, to the number of measurement samples of the first SRS in the second time period. For example, if the number of measurement samples of the first SRS in the second time period is 100, and 60 measurement samples in 100 measurement samples are greater than the fourth threshold value, the measurement result is represented as 60%. The second time period, which is set to measure the first SRS, can be configured. The first time period and the second time period may be the same or different. The fourth threshold may be configured.

[0177] The information about one or more measurement results includes indication information of one or more measurement results and/or second indication information.

[0178] The measurement result indication information is information indicating the measurement result, and the terminal apparatus can directly report the measurement result, the measurement result index, the measurement result ID, or other information indicating the measurement result. In this embodiment of this application, the measurement result message is mainly used as an example for description. It can be understood that, as long as the terminal can finally notify the network device of the associated measurement result information so that the network device knows the measurement result, the decision should fall within the protection scope of the decisions in the embodiments of this application.

[0179] The second indication information is the indication information of the second terminal, respectively corresponding to one or more measurement results. In other words, the second indication information may be used to distinguish between different second terminals. Optionally, the second indication information includes one or more of the first SRS resource indication information, the first SRS sequence, or the first SRS sequence set. Of course, the second indication information may alternatively be other information that can be used to distinguish between different second terminals. A detailed description of the second indication information is given in the following description.

[0180] S303: The first terminal receives the first indication information.

[0181] The first indication information indicates that the first terminal is to report measurement result information. Optionally, the first indication information indicates at least one of the number of measurement results reported by the first terminal, or features of the reported measurement result.

[0182] Optionally, the first indication information is preconfigured in the first terminal, or the first indication information is configured by the network device for the first terminal.

[0183] The sequence of steps 303, 301, and 302 is not limited, and step 303, step 301, and step 302 may be performed sequentially or simultaneously. For example, the first terminal may first obtain the first indication information; and then receive the first SRS from the second terminal and measure the measurement result of the first SRS. Alternatively, the first terminal may first receive the first SRS from the second terminal and then obtain the first indication information.

[0184] Optionally, the feature of the reported measurement may include that the reported measurement is the RSRP of the first SRS, that the reported measurement is the RSSI, or that the reported measurement is the RSRP and the RSSI of the first SRS.

[0185] S304: The first terminal sends, based on the first indication information, information about one or more measurement results to the network device.

[0186] Accordingly, the network device receives information about one or more measurement results from the first terminal.

[0187] According to the communication method provided in this embodiment of this application, after a specific second terminal sends the first SRS, if the first terminal can obtain by tracking the first SRS of the second terminal, the first terminal can measure the signal strength of the first SRS and obtain information about result of the first SRS measurement. In addition, the first terminal can further report measurement result information to the network device, so that the network device can receive measurement results of various second terminals. Thus, subsequently, the network device can learn, based on one or more measurement results, the CLI levels caused by different second terminals for the first terminal, and perform some CLI reduction operations.

[0188] In addition, when the network device does not receive the measurement result, the network device can learn, based on the second indication information corresponding to the measurement result, the specific second terminal that causes interference to the first terminal. For example, when the first terminal measures a specific first SRS and returns the second indication information of the first SRS to the network device, the network device may determine the transmitting end of the first SRS, where the second indication information includes, but is not limited to, at least one of the first SRS sequence, a set of sequences the first SRS or the resource identifier of the first SRS. For example, the first terminal measures a particular first SRS and returns a resource identifier of the first SRS to the network device. Therefore, the network device can know the specific second terminal that sends the first SRS using the resource indicated by the resource identifier, and the network device can determine the interferer that causes the CLI for the first terminal.

[0189] The following describes various ways in which the first terminal reports the measurement result when the first indication information is different, that is, specific implementations of S303 and S304. The following procedures take as an example that the first indication information is configured by the network device. For the implementation procedure in which the first indication information is preconfigured in the terminal, refer to the following description. Details in this embodiment of this application are not specifically described.

[0190] In some embodiments of FIG. 7, S303 can be specifically implemented as follows.

[0191] S3031: The first terminal receives the first indication information from the network device.

[0192] The first indication information indicates that the first terminal should send information about the N largest measurement results in the measurement of at least one second terminal. In other words, the first indication information indicates that the first terminal is to send the N largest measurement results from the measurement of at least one second terminal and/or the second indication information corresponding to the N largest measurement results, respectively; or send the N smallest measurement results of the measurement of the at least one second terminal and/or the second indication information corresponding to the N smallest measurement results, respectively. N is an integer greater than or equal to 1. In other words, the first terminal may report the N largest measurements or report the second indication information corresponding to the N largest measurements, or report both the N largest measurements and the second indication information corresponding to N the highest measurement results. Alternatively, the first terminal may report the N smallest measurements, or report the second indication information corresponding to the N smallest measurements, or report both the N smallest measurements and the second indication information corresponding to the N smallest measurements. For information on the principle of such descriptions below, refer to the description in this document.

[0193] Optionally, the value of N may be the same as the number of measurements of at least one second terminal. That is, the first terminal reports all measurement results obtained as a result of monitoring. Thus, the network device receives all measurements. Since the signal strength of the first SRSs of various second terminals can be comprehensively and accurately reflected using all measurements, the network device can know the comprehensive and accurate CLI states between the first terminal and various second terminals, and further perform some CLI reduction operations based on the accurate CLI states.

[0194] Optionally, the value of N may be less than the number of measurements of at least one second terminal. Only a part of the measurement result is reported, so that the signaling overhead for reporting the measurement result is reduced.

[0195] Optionally, the N measurement results are the N largest measurement results in the measurement result of at least one second terminal, that is, a feature of the reported measurement result is that the reported measurement result is the largest measurement result. N is an integer greater than or equal to 1. The value of N can be pre-configured in the terminal by the supplier in accordance with the specification; or the value N is transmitted from the network device to the terminal and the terminal stores the value N. In a possible implementation, the number of measurements from at least one second terminal is greater than or equal to N, and the first terminal sends N measurements to the network device. For example, the first terminal acquires by monitoring the first five SRSs from different second terminals, and the measurement values of the first five SRSs are sequentially: measurement result 3 (corresponding to SRS 3 of UE 3) > measurement result 2 (corresponding to SRS 2 of UE 2) > measurement result 5 ( corresponding to SRS 5 of UE 5) > measurement result 4 (corresponding to SRS 4 of UE 4) > measurement result 1 (corresponding to SRS 1 of UE 1). Assuming that the value of N is 3, the first terminal separately reports the measurement results of UE 3, UE 2 and UE 5 to the network device.

[0196] Thus, when the measurement result of a particular second terminal is larger, the degree of CLI caused by the second terminal to the first terminal is generally higher. The network device can approximately know the CLI state between the first terminal and the other terminal based on the measurement result with the highest CLI level to perform some CLI reduction operations, thereby reducing the CLI between the first terminal and the other terminal. It can be recognized that only a part of the measurement result is reported, so that the signaling overhead for reporting the measurement result is reduced.

[0197] S304 may in particular be implemented as the following step:

[0198] S3041: The first terminal sends, based on the first indication information, N measurement information to the network device.

[0199] Accordingly, the network device receives information about N measurements from the first terminal.

[0200] In some other embodiments, with reference to FIG. 8, S303 may be specifically implemented as the next S3032.

[0201] S3032: The first terminal receives the first indication information from the network device.

[0202] The first indication information indicates that the first terminal sends information about J measurement results that are the measurement result of at least one second terminal and that is greater than or equal to the first threshold value, where the information about J measurement results includes an indication of information J measurement results and/or second indication information, the second indication information is second terminal indication information corresponding to J measurement results, and J is a positive integer.

[0203] Optionally, one or more measurement results reported by the first terminal are information about J measurement results. J is a positive integer, and J is transmitted from the network device to the first terminal, or J is preconfigured in the first terminal. Specifically, the J measurement results reported by the first terminal are the J measurement results that are the measurement result of at least one second terminal and that are greater than or equal to the first threshold value. Thus, only a part of the measurement result is reported, so that the signaling overhead for reporting the measurement result can be reduced. For example, if the first terminal receives five first SRSs from other terminals by monitoring and J is 3, the first terminal reports three measurements greater than or equal to the first threshold. In case the number of measurement results greater than or equal to the first threshold value is less than J, for example, there is only one measurement result greater than or equal to the first threshold value, the first terminal may report only said measurement result. Alternatively, the first terminal reports the measurement result, then selects the two largest measurement results from the remaining four measurement results, and reports the two largest measurement results. Otherwise, if there is no measurement result greater than or equal to the first threshold value, the first terminal may not report the measurement result. Alternatively, J=3 measurements are randomly selected for the report. In another case, when the number of measurement results greater than or equal to the first threshold value is greater than J, the first terminal reports only J measurement results. Alternatively, the first terminal reports all measurement results greater than or equal to the first threshold.

[0204] Of course, another threshold may alternatively be set, such as a third threshold. Optionally, the first terminal reports a measurement result greater than or equal to the third threshold value. Optionally, when there is no measurement result greater than or equal to the third threshold value, the first terminal reports one or M largest measurement results. 1 or M is configured by the network device, or 1 or M is preset in the first terminal. M is a positive integer.

[0205] Optionally, the aforementioned thresholds may be pre-configured in the terminal or may be transmitted from the network device to the terminal. Alternatively, some thresholds are preset in the terminal and some thresholds are configured by the network device.

[0206] In contrast to the measurement result presentation method shown in FIG. 7, where N are the measurements presented in the procedure shown in FIG. 7 may be less than the preset first threshold value, in accordance with the procedure shown in FIG. 8, it may be indicated that the UE reports information about J measurement results greater than or equal to the first threshold value. When the number of measurement results that are in the measurement results actually obtained by the UE through the measurement and which is greater than or equal to the first threshold value is less than J, only the measurement result greater than or equal to the first threshold value may be reported. "Less" means less than something.

[0207] In this way, only a portion of the measurements are sent, so that the signaling overhead can be reduced. In addition, the J largest measurements can be sent so that the network device becomes aware of the second terminal that causes more severe CLIs for the first terminal, and this helps the network device formulate a mitigation policy based on the most severe CLIs. Alternatively, the J smallest measurements are reported so that the network device can become aware of a second terminal that invokes relatively weak CLIs for the first terminal and may not perform another operation on the second terminal.

[0208] S304 may be specifically implemented as the following S3042.

[0209] S3042: The first terminal sends to the network device, based on the first indication information, information about J measurement results that are found as a measurement result of at least one second terminal and that is greater than or equal to the first threshold value. The measurement information J includes indication information of J measurement results and/or second indication information, and the second indication information is indication information of the second terminal corresponding to J measurement results.

[0210] In some other embodiments, with reference to FIG. 9, the above S303 can be specifically implemented as the following S3033.

[0211] S3033: The first terminal receives the first indication information from the network device.

[0212] The first indication information indicates that the first terminal sends information about W measurement results that are measured by at least one second terminal and that are less than or equal to the second threshold value. The measurement result information W includes indication information W of measurement results and/or second indication information, where the second indication information is second terminal indication information corresponding to W measurement results, and W is a positive integer.

[0213] For example, if the number of measurement results of at least one second terminal is greater than W, the first terminal reports W measurement results. In this way, it is possible to reduce the signaling overhead. In case the number of measurement results of at least one second terminal is less than W, the first terminal may report all measurement results of at least one second terminal. In case there is no measurement result less than or equal to the second threshold, the first terminal may randomly select W measurement results (eg, select W smallest measurement results) from the measurement result of at least one second terminal, and report W measurement results. Alternatively, if there is no measurement less than or equal to the second threshold, the first terminal may not report any measurement. The number of measurement results reported by the first terminal is not specifically limited in this embodiment of this application.

[0214] The above S304 may be specifically implemented as the following S3043.

[0215] S3043: The first terminal sends to the network device, based on the first indication information, information about W measurement results that are measured by at least one second terminal and that are less than or equal to the second threshold value. The measurement information W includes indication information W of measurement results and/or second indication information, where the second indication information is indication information of the second terminal corresponding to W measurement results.

[0216] In some other embodiments, with reference to FIG. 10, the above step S304 may alternatively be implemented as the following steps.

[0217] S3044: The first terminal sends information about the first measurement result to the network device at the first time. The first measurement result information includes the first measurement result and/or the second indication information corresponding to the first measurement result.

[0218] S3045: The first terminal sends the second measurement result information to the network device at the second time point, that is, sends the second measurement result and/or the second indication information corresponding to the second measurement result, where the interval between the first time point and the second time point is this is a pre-set period of time. The difference between the second measurement result and the first measurement result is greater than or equal to the preset difference.

[0219] In this application, the first time point has no correlation with the first time period, and the second time point has no correlation with the second time period.

[0220] In other words, there is a time interval between times when different measurement results are reported. In a possible implementation, the difference between the second measurement result and the first measurement result is greater than or equal to a predetermined difference. In other words, when the measurement results are reported twice, the first terminal reports the measurement result at the second time point only if it is determined that the difference between the measurement result at the second time point and the measurement result at the first time point is greater than or equal to a predetermined difference.

[0221] The time interval between two reporting times, that is, a predetermined period of time, may be preconfigured or may be transmitted from the network device to the first terminal. The preset difference may be preconfigured or may be transmitted from the network device to the first terminal.

[0222] The measurement results of the two times may be measurement information specific to the first SRS of the same second terminal. In other words, the first SRS of the second terminal may be measured a plurality of times, and the measurement results of the plurality of times are reported periodically. That UE 1 is the first terminal and UE 2 is the second terminal is used as an example. In a process in which the UE 1 periodically reports the measurement result to the UE 2, the difference between the measurement results of the two times is greater than or equal to a predetermined difference. This means that the measurement result at the second time point is larger than the measurement result at the first time point, and the difference between the measurement result at the second time point and the measurement result at the first time point is equal to a predetermined difference. Alternatively, the measurement result at the second time point is larger than the measurement result at the first time point, and the difference between the measurement result at the second time point and the measurement result at the first time point is greater than a predetermined difference. Alternatively, the fact that the difference between the measurement results of the spirit of time is greater than or equal to the predetermined difference may be that the measurement result at the second time point is less than the measurement result at the first time point, and the difference between the measurement result at the second time point time and the measurement result at the first time is equal to a predetermined difference. Alternatively, the measurement result at the second time point is smaller than the measurement result at the first time point, and the difference between the measurement result at the second time point and the measurement result at the first time point is larger than a predetermined difference. In other words, only when the measurement result at the second time point is very different from the measurement result at the first time point, the first terminal reports the measurement result, which is the result at the second time point and is characteristic of the same second terminal. According to the above method, for the same second terminal, the first SRS may be measured a plurality of times in order to improve the accuracy of the measurement result of the first SRS of the second terminal. In addition, measurement results with similar values usually indicate that the position, signal quality, etc. the second terminal does not change or changes slightly. In this case, the obtained measurement result of the first SRS of the second terminal may be redundant information, and the network device may not need redundant information to make a decision. Therefore, in this embodiment of this application, the first terminal reports only the measurement result, which is the measurement result at the second time point and which is very different from the measurement result at the first time point. Thus, it is possible to prevent the first terminal from reporting an excessive measurement result with the same value, and the signaling overhead is reduced.

[0223] Alternatively, the measurement results of the two times may be measurement information specific to the first SRS of the different second terminals. For example, that the first terminal is UE 1 and the second terminals are UE 2 and UE 3 is used as an example. At the first time, UE 1 sends the measurement result of the first SRS of UE 2 to the network device. At the second time, UE 1 sends the measurement result of the first SRS of UE 3 to the network device. In this case, that the difference between the measurement results of the two times is greater than or equal to the preset difference may be that the measurement result of UE 3 is larger than the measurement result of UE 2, and the difference between the measurement result of UE 3 and the measurement result of UE 2 is greater than or equal to a predetermined difference. Alternatively, that the difference between the measurement results of the two times is greater than or equal to the predetermined difference may be that the measurement result of UE 3 is less than the measurement result of UE 2, and the difference between the measurement result of UE 3 and the measurement result of UE 2 is greater than or equal to predetermined difference.

[0224] In some other embodiments, the first terminal, the second terminal, and the network device may configure the first SRS with some interaction procedures to help the first terminal measure the first SRS. In particular, as shown in FIG. 11, the interaction procedure includes the following steps.

[0225] S1101: The first terminal sends the first capability information to the network device.

[0226] Accordingly, the network device receives the first capability information from the first terminal.

[0227] The first capability information indicates CLI measurement capability information. The first capability information includes at least one of the number of first SRSs that can be tracked by the first terminal per unit of time, whether the first terminal can track consecutive symbols, the maximum number of symbols that can be tracked by the first terminal per unit of time, or the maximum number of consecutive characters that can be tracked by the first terminal per unit of time. The unit of time can be a slot. One unit of time includes one slot, or includes a plurality of slots, or includes one duration, where one duration includes one or more slots.

[0228] In another embodiment, step S1101 is optional, that is, this step may not be performed, and the following steps continue to be performed.

[0229] In some other embodiments, the first terminal may further report the first capability information to the operation administration management (OAM) system.

[0230] S1102: The first terminal sends the second capability information to the network device.

[0231] Accordingly, the network device receives the second capability information from the first terminal. The second capability information indicates the ability of the first terminal to report the measurement result. The second capability information indicates the number of measurement results that can be reported by the first terminal to the network device, and the measurement result includes a measurement result specific to at least one first SRS. The measurement result of the first SRS indicates the signal level of the first SRS from the second terminal, and may further indicate the level of CLIs caused by the second terminal for the first terminal. For details of the measurement result of the first SRS, refer to the following description. In addition, when the measurement result is further referred to in the following, the measurement result generally refers to the measurement result specific to the first SRS. This is uniformly described here, and the details are not described further.

[0232] Optionally, the second capability information may also be referred to as the first terminal's reporting capability.

[0233] The measurement result may further include another type of measurement result. For example, the measurement result may include an RSRP measurement result, an RSRQ measurement result, or a received signal strength indicator (RSSI) measurement result. In other words, the first terminal allows the network device, using the second capability information, to know the number of measurements that are specific to RSRP and that can be transmitted by the first terminal, and/or to know the number of measurements that are specific to RSRQ, and/or to know the number measurement results specific to the RSSI and/or to know the number of measurements that are the measurements of the first SRS that can be reported. In addition, the network device performs an appropriate configuration for the first terminal based on the number of measurement results that can be transmitted by the first terminal.

[0234] In another embodiment, step S1102 is optional, that is, this step may not be performed, and the following steps continue to be performed.

[0235] S1103: The first terminal sends third capability information to the network device.

[0236] Accordingly, the network device receives the third capability information from the first terminal.

[0237] The third capability information indicates a multiplexing relationship between the second resource and the first resource for receiving the first SRS, and the multiplexing relationship includes at least one of time division multiplexing or frequency division multiplexing. Frequency division multiplexing, specifically: The first resource and the second resource overlap completely in the time domain, and are contiguous or non-overlapping in the frequency domain; or the first resource and the second resource partially overlap (overlap) in the time domain, and are adjacent or not overlap in the frequency domain. Time division multiplexing: The first resource and the second resource completely overlap in the frequency domain and are adjacent or do not overlap in the time domain; or the first resource and the second resource overlap (overlap) in the frequency domain and are adjacent or do not overlap in the time domain.

[0238] The first resource is the resource used to receive the first SRS. The second resource is the resource used to transfer data. The data transmission includes one or more of the following: a physical downlink shared channel (PDSCH), a physical uplink shared channel (PUSCH), a physical random access channel (physical random access channel (PRACH), physical downlink control channel (PDCCH), channel state indicator reference signal (CSI-RS), physical uplink control channel , PUCCH), physical sidelink control channel (PSCCH), physical sidelink shared channel (PSSCH), or physical sidelink feedback channel (PSFCH) . Of course, the data transfer may alternatively be a data transfer of another form.

[0239] It should be noted that the third capability information indicates a multiplexing relationship between the first resource and the second resource, may be that the third capability information indicates one or more specific multiplexing relationships between the first resource and the second resource, and the resource multiplexing relationship may be supported by the first terminal. For example, the third capability information indicates that time division multiplexing is performed between the first resource and the second resource. Alternatively, the third capability information indicates one or more specific multiplexing relationships that cannot exist between the first resource and the second resource, that is, one or more specific resource multiplexing relationships that are not supported by the first terminal. For example, the third capability information indicates that frequency division multiplexing cannot be performed between the first resource and the second resource, or that the first resource and the second resource cannot have an inclusion (eg, overlap) relationship in the time domain and frequency domain, or that the first resource and the second resource cannot overlap in the time and frequency domains.

[0240] Thus, when receiving the third capability information and configuring the first resource and the second resource for the terminal, the network device properly performs the resource configuration depending on whether the terminal supports the resource multiplexing relationship to reduce the possibility of collision between the first resource and the second resource .

[0241] In some embodiments, the resource occupied by the first SRS is different from the resource used for downlink transmission, and the resource occupied by the first SRS is different from the resource used for uplink transmission. Downlink transmission includes PDCCH, PDSCH, synchronization signal (SS), or physical broadcast channel (PBCH). The uplink transmission includes at least one of PUCCH, PUSCH, PRACH, or a second SRS. The second SRS is not used to measure CLI. Of course, the uplink transmission or downlink transmission may alternatively be an uplink transmission or other form of downlink transmission.

[0242] In other words, when configuring uplink transmission or downlink transmission, the network device considers whether the uplink transmission or downlink transmission overlaps the first SRS. If an overlap occurs, the network device configures the resource as a resource used for uplink or downlink transmission, or configures the resource as a resource used for receiving the first SRS, to avoid conflict between the uplink or downlink transmission and the first SRS on the same resource.

[0243] Alternatively, the behavior of the terminal is defined as follows: When the resource occupied by the first SRS and the resource used for downlink transmission have part of the same resources, or the resource occupied by the first SRS and the resource used for uplink transmissions have part of the same resources, on the same resource the first SRS is detected by the terminal and the downlink transmission is discarded by the terminal, or the downlink transmission is detected by the terminal and the first SRS is discarded by the terminal, or the first SRS is detected by the terminal and the uplink transmission is discarded by the terminal, or the uplink transmission is detected by the terminal and the first SRS is discarded by the terminal.

[0244] That the network device configures any of the above uplink transmissions is used as an example. On the same resource, the network device configures the resource as a resource used for uplink transmission or as a resource used for receiving the first SRS. In addition, the network device may indicate to the first terminal to preferentially detect the uplink transmission and skip the discovery of the first SRS when performing discovery on the resource, that is, discard the first SRS. Alternatively, the first terminal preferably detects the first SRS and skips detection of the uplink transmission.

[0245] In another embodiment, step S1103 is optional, that is, this step may not be performed, and the following steps continue to be performed. When step S1103 is optional, the first terminal acquires the third capability information through presetting.

[0246] The execution sequence of S1101-S1103 is not limited in this embodiment of this application. For example, the first terminal may first send the first capability information to the network device, and then send the second capability information to the network device; or the first terminal may first send the third capability information to the network device, and then send the first capability information to the network device.

[0247] Any of the first capability information, the second capability information, or the third capability information may be placed by the terminal in a MAC packet or a data packet and sent to the network device.

[0248] S1104: The first terminal receives configuration information.

[0249] Optionally, the first terminal receives configuration information from the network device. Alternatively, the configuration information is pre-configured in the first terminal. Alternatively, part of the configuration information is received from the network device and another part of the configuration information is set in advance.

[0250] In an exemplary implementation, the network device determines the configuration information based on at least one of the above capability information (eg, second capability information) of the first terminal. Of course, the network device may alternatively determine the configuration information based on the policy of the network device and send the configuration information to the first terminal. The method for determining the configuration information by the network device is not limited in this embodiment of this application.

[0251] In some embodiments, the configuration information indicates at least one of the following:

[0252] 1. Reported measurement result is RSRP, or RSSI, or RSRP and RSSI. The measurement result indicates the signal level of the first SRS.

[0253] In this application, the measurement result showed that the signal level of the first SRS is RSRP, or RSSI, or RSRP and RSSI. RSRP may be replaced by SRS-RSRP or may be replaced by CLI-RSRP. RSSI may be substituted for SRS-RSSI or may be substituted for CLI-RSSI.

[0254] 2. Information about the available first resource or information about the configured first resource.

[0255] Optionally, the available first resource is a resource that can be used by the interfering terminal to send the first SRS. In an exemplary implementation, the resource pool may be prespecified and the resource pool is the first resource available. The available first resource information includes one or more of a resource pool start slot position, a number of resource pool slots, an orthogonal frequency division multiplexing (OFDM) start symbol position in a slot, a number of symbols in a slot, the position of the initial physical resource block (PRB), the number of PRBs, the position of the initial resource element (RE), or the number of REs. Any one or more of the plurality of slots, the plurality of symbols, or the plurality of PRBs may be consecutive or non-consecutive.

[0256] Optionally, the network device may also limit the minimum number of PRBs of the first resource. For example, when COMB is 2, the number of PRBs occupied by the first resource is set to at least 8; or when COMB is 4, the number of PRBs is set to at least 16.

[0257] Thus, subsequently, when the first terminal serves as an interfering terminal, the first terminal may select from the available first resource (ie, the previous resource pool) the resource used to send the first SRS.

[0258] Optionally, the configured first resource is a resource that is used by the interfering terminal to send the first SRS. The configured first resource information includes one or more of a start slot position, a number of slots, a start OFDM symbol position in a slot, a number of symbols, a start PRB position, a PRB number, a start RE position, or a RE number. Any one or more of the slot set, symbol set, PRB set, or RE set may be sequential or non-consecutive.

[0259] 3. Reference information used to measure RSSI.

[0260] The reference information used for measuring RSSI (in other words, used for transmitting RSSI) includes one or more of the reference subcarrier spacing (SCS), the position of the start slot used for measuring RSSI, the number of slots used for the RSSI measurement, the position of the OFDM start symbol used for the RSSI measurement, the number of symbols used for the RSSI measurement, the position of the start PRB used for the RSSI measurement, the number of PRBs used for the RSSI measurement, the position of the start RE used for the RSSI measurement, or the number RE used to measure RSSI. Any one or more of the slot set, symbol set, PRB set, or RE set may be consecutive or non-consecutive.

[0261] After configuring the reference subcarrier spacing used for RSSI measurement, the subcarrier spacing in the active bandwidth part (BWP) in which the first terminal is located may be different from the reference subcarrier spacing used for RSSI measurement. Symbols and bandwidth defined by different subcarrier spacings may be different. For example, it is assumed that the sub-carrier spacing in the active BWP is 20 kHz and the reference sub-carrier spacing used for measuring RSSI is 40 kHz. In this case, when the network device configures the first terminal to detect four symbols (that is, symbols used for RSSI measurement) when measuring RSSI, because the reference subcarrier spacing used for measuring RSSI doubles (from 20 kHz to 40 kHz), when the first terminal measures RSSI, the first terminal actually detects two symbols.

[0262] In some case, the network device configures the number of symbols used to measure RSSI as an odd number. Thus, the number of symbols that are actually measured and that are output by the first terminal based on the relationship between the subcarrier spacing in the active BWP and the reference subcarrier spacing used for RSSI measurement may not be an integer. Therefore, the number of symbols that are actually measured by the terminal and the bandwidth of the terminal must be redefined.

[0263] In an exemplary implementation, the number of symbols actually measured is determined by the method of rounding up or down. For example, the UE is configured by the network device to measure seven symbols, but the reference subcarrier spacing used to measure RSSI is twice the subcarrier spacing in the active BWP. Therefore, in this case, the UE is actually configured to measure 3.5 symbols. Optionally, after rounding to 3.5, the UE actually measures three symbols. Alternatively, after rounding 3.5, the UE actually measures four symbols. In other words, when the symbol or the number of symbols determined by the reference subcarrier spacing used for RSSI measurement does not satisfy the integer number of symbols specified by the SCS in the active BWP, the UE may determine the number of symbols that are actually measured by the rounding up or down method, to satisfy the requirement specified by the SCS in the active BWP for an integer number of characters.

[0264] In addition, when at least one of the RB, the number of RBs, the PRB, the number of PRBs, the REs, or the number of REs determined by the reference subcarrier spacing used for RSSI measurement does not meet the requirement determined by the SCS in the active BWP, the integer number RB/RE, the UE may also calculate any of the integer number of RB/REs with reference to the above method. In an exemplary implementation, the number of characters may be rounded down and the number of RB/REs may be rounded up; or the number of characters may be rounded up and the number of RB/REs may be rounded down; or another rounding method is used. The rounding method can be configured or preset in the terminal.

[0265] 4. Reference information used to measure RSRP.

[0266] For more information, refer to the configured first resource information. Details are not described here again.

[0267] It should be noted that the reference information used for measuring RSRP and the reference information used for measuring RSSI can be configured separately and do not affect each other. The configured transmission resources may have several of the following relationships. For example, the first SRS used to measure RSRP occupies resource 1, and the first SRS used to measure RSSI occupies resource 2. Resource 1 and resource 2 may overlap partially, or may not overlap, or may overlap completely. In this application, "borrow resource" can be replaced by "use resource".

[0268] In addition, the number of RSSI that the first terminal can report and the number of RSRP that the first terminal can report may be different or may be the same. The quantity can be flexibly adjusted based on the actual application scenario.

[0269] 5. At least one of a sequence, a set of sequences, or resource indication information of the first SRS used for sending/measuring. Each set of sequences includes at least one sequence.

[0270] In particular, the configuration information is a root sequence or a set of root sequences of the first SRS, and each set of root sequences includes at least one root sequence. Thus, the rotation may be performed based on the configured root sequence to obtain the first SRS to be sent/measured. Alternatively, a root sequence is randomly selected from a set of root sequences, and based on the root sequence, a rotation is performed to obtain the first SRS to be sent/measured.

[0271] Specifically, the configuration information is any one or more of a root sequence, a cyclic shift, a set of root sequences, or a cyclic shift set of the first SRS. Each set of root sequences includes at least one root sequence. Thus, the first SRS to be sent/measured can be obtained based on the configured root sequence and the configured cyclic shift. Alternatively, a root sequence is randomly selected from a set of root sequences, and based on the root sequence, a rotation is performed to obtain the first SRS to be sent/measured.

[0272] Specifically, the resource indication information includes a resource or resource set used for transmission. The resource used for transmission may be indicated by a resource identifier (index/ID), such as an SRS resource index. The resource set may be specified using a resource set identifier (index/ID), such as an SRS set resource index or an SRS resource set index.

[0273] 6. Whether to perform rate negotiation for the first terminal.

[0274] Performing rate matching for the first terminal means that the uplink or downlink information transmitted by the first terminal is repeated (repeated) or punctured (punctured) to match the throughput of the physical channel, so that the uplink or downlink information rate meets the requirement. For details on rate matching, refer to the current technology. Details are not described here. Thus, subsequently, if rate matching is to be performed, the first terminal sends information in a repeat or puncture mode to match the throughput of the physical channel.

[0275] 7. The measurement result information includes both the measurement result and the second indication information.

[0276] When the measurement result is reported, the second indication information of the first SRS used for the measurement is also reported. The second indication information of the first SRS includes one or more of the first SRS resource indication information or the first SRS sequence. In embodiments of this application, the first SRS resource indication information includes one or more of a first SRS resource identifier, a first SRS resource index, a first SRS set resource identifier, or a first SRS set resource index. That is, sending information about one or more measurement results to the network device includes: reporting the second indication information of the first SRS used for measurement when sending the measurement result. The first set of SRSs includes one or more first SRSs, and the resource identifier of the first set of SRSs may be identifiers of all resources for transmitting the plurality of first SRSs.

[0277] In other words, the configuration information may indicate that the first terminal should report some other information when reporting the measurement result. Thus, information such as a resource or sequence related to the first terminal can be carried in one message. The measurement result and the second indication information have a one-to-one correspondence in the communicated message.

[0278] 8. The measurement result information only includes the second indication information. When the measurement result information is reported, only the second indication information of the first SRS, which is used for measurement and which satisfies the measurement result requirement, is reported. That the measurement result requirement is fulfilled means that the requirement of the first indication information is fulfilled. The second indication information of the first SRS includes one or more of the first SRS resource indication information or the first SRS sequence. In embodiments of this application, the first SRS resource indication information includes one or more of a first SRS resource identifier, a first SRS resource index, a first SRS set resource identifier, or a first SRS set resource index. That is, sending information about one or more measurement results to the network device includes: reporting the second indication information of the first SRS used for measurement when sending the measurement result. The first set of SRSs includes one or more first SRSs, and the resource identifier of the first set of SRSs may be identifiers of all resources for transmitting the plurality of first SRSs.

[0279] In other words, the configuration information may indicate that the first terminal should only report some other information when the first terminal reports measurement result information. Thus, the measurement result is not directly transmitted, and information such as a resource or sequence related to the first terminal may be transmitted. The measurement result and the second indication information have a one-to-one correspondence.

[0280] 9. The measurement result information includes only the measurement result.

[0281] In some other embodiments, the configuration information may alternatively indicate how the measurement result is reported by the first terminal. The measurement result reporting method includes reporting the number of measurement results and reporting the characteristics of the measurement result. When the measurement result reporting method is at least one or more of the following methods, the first terminal performs reporting by the measurement result reporting method specified in the configuration information. In particular, the measurement result reporting method may be at least one or more of the following methods.

[0282] Method 1: The first terminal reports information about N measurements according to the procedure of the method shown in FIG. 7.

[0283] Method 2: Different threshold values may be set, and measurements to be reported are determined based on the different threshold values. That is, the first terminal reports measurement result information according to the procedure of the method shown in FIG. 8.

[0284] Method 3: The first terminal reports measurement result information W according to the method procedure shown in FIG. 9.

[0285] Method 4: The first terminal reports information about K measurements of the second terminal in the first cell, and reports information about I measurements of the second terminal in the second cell. I and K are both positive integers and can be the same or different. In other words, for second terminals in different cells, the first terminal may set different upper limits on the number of measurements for different cells.

[0286] Method 5: The measurement result reported by the first terminal is the H largest measurement results that are measured by at least one second terminal and that are greater than or equal to the result threshold, and H is a positive integer.

[0287] Method 6: The first terminal reports information about various measurement results based on a predetermined time interval. That is, the first terminal reports the measurement result according to the procedure shown in FIG. 10.

[0288] Method 7: The first terminal reports the second indication information of the first SRS.

[0289] The message of the second indication information of the first SRS includes the message of the second indication information corresponding to the measurement result when the measurement result is reported. That is, the second indication information is reported with a measurement result that has a one-to-one correspondence with the second indication information.

[0290] Optionally, when two measurement results are reported, the corresponding resource IDs/resource indexes of the first two SRSs corresponding to the two measurement results are also reported, so that when receiving the measurement results, the network device becomes aware of the specific terminals from which interference is received corresponding to the measurement results.

[0291] Optionally, when two measurement results are reported, the corresponding resource IDs/resource indexes of the first SRSs of the first two SRSs corresponding to the two measurement results are also reported, so that when receiving the measurement results, the network device learns about the specific terminals from which interference is received, corresponding to the measurement results.

[0292] Optionally, when two measurement results are reported, the respective resource IDs/resource indices of the first two SRSs corresponding to the two measurement results and the respective resource IDs/resource indices of the first sets of SRSs of the first two SRSs, that is, the respective resource IDs of the first two SRSs, are also reported. and the corresponding resource IDs of the first SRSs of the first two SRSs are also reported; or the respective resource identifiers of the first two SRSs and the respective resource indexes of the first sets of SRSs of the first two SRSs are also reported; or the respective resource indices of the first two SRSs and the respective resource indices of the first sets of SRSs of the first two SRSs are also reported; or the respective resource indexes of the first two SRSs and the respective resource identifiers of the first sets of SRSs of the first two SRSs are also reported. Therefore, when receiving the measurement results, the network device becomes aware of the specific terminals from which interference is received corresponding to the measurement results.

[0293] Optionally, when two measurement results are reported, the corresponding sequence of the first two SRSs corresponding to the two measurement results is also reported, so that when receiving the measurement results, the network device becomes aware of the specific terminals from which interference is received corresponding to the measurement results.

[0294] Reporting the second indication information of the first SRS includes: reporting the second indication information with a measurement result in one or more measurement results that have a one-to-one correspondence with the second indication information.

[0295] Optionally, when two measurement results are reported, the corresponding resource identifiers/resource indices and the corresponding sequences of the first two SRSs corresponding to the two measurement results are also reported, so that when receiving the measurement results, the network device learns about the specific terminals from which interference is received corresponding to measurement results.

[0296] Optionally, a sequence or set of sequences of the first SRS and the second indication information may be reported using the same piece of configuration information. The sequence or set of sequences of the first SRS and the second indication information may be reported using two pieces of configuration information, respectively. This is not limited in this embodiment of the present application.

[0297] Optionally, reporting the second indication information of the first SRS includes reporting only the second indication information so that the network device can know, without needing to obtain a measurement result, the specific terminal that causes the strongest or weakest interference.

[0298] Of course, the first terminal may alternatively report the measurement result in a different manner and report a different number of measurement results. In addition, the reported measurement result may have another feature. Examples are not listed here one by one in this embodiment of this application.

[0299] Any one or more of N, J, M, K, I, or H, the first or second threshold is configured by the network device via RRC signaling.

[0300] Optionally, in addition to reporting based on the configuration information of the network device, the first terminal may alternatively directly report based on any one or more of the above measurement result reporting methods. In other words, the first terminal does not need to receive the configuration information delivered by the network device to know how to report the measurement result, or the first terminal directly performs the report based on the preset. In this application, report means that the terminal sends data information to a network device, where the data information includes any one or more measurement results or second measurement result indication information.

[0301] For example, the first terminal directly reports on method 1, or the first terminal directly reports on method 1 and method 6, or the first terminal directly reports on method 2 and method 6.

[0302] In another embodiment, step S1104 is optional, that is, this step may not be performed, and the following steps continue to be performed. When step S1104 is optional, the first terminal obtains the configuration information by presetting.

[0303] S1105: The network device configures the first SRS of the second terminal.

[0304] In some embodiments, the network device configures the first SRS of the second terminal based on at least one of the above pieces of capability information (eg, first capability information).

[0305] Optionally, the first capability information may also be referred to as a measurement capability.

[0306] The following describes a method in which a network device configures a first SRS of a second terminal using an example in which the unit of time is a slot, the first terminal is UE 1, and the second terminals are UE 2 and UE 3.

[0307] Optionally, the network device learns, based on the first capability information reported by UE 1, that the number of first SRS that UE 1 can monitor in a slot is P, where P is an integer greater than or equal to 1. Thus, the network the device configures the number of first SRS that can originate from the second terminal to be less than or equal to P. For example, if the number of first SRS that UE 1 can monitor in a slot is 8, and UE 2 and UE 3 multiplex the slot, the network device can configure the UE 2 to send a maximum of the first two SRSs in a slot, and the network device configures the UE 3 to send a maximum of the first six SRSs in the same slot. Alternatively, if UE 2 and UE 3 do not send the first SRS in one slot, the network device may configure UE 2 to send a maximum of eight first SRS in a slot, and the network device configure UE 3 to send a maximum of eight first SRS in another slot. Thus, regardless of whether UE 2 and UE 3 multiplex the same slot to send the first SRS, in a slot, UE 2 or UE 3 sends a maximum of eight first SRS, which does not exceed the upper limit of the number of first SRS monitored by UE 1 in slot.

[0308] Optionally, the network device learns, based on the first capability information reported by UE 1, that UE 1 can monitor consecutive symbols, and accordingly, the network device configures UE 2 to send the first SRS on consecutive symbols. Alternatively, the network device configures the UE 3 to send the first SRS on consecutive characters. Alternatively, if UE 2 and UE 3 multiplex the same slot to send the first SRS, the network device may allocate multiple consecutive symbols for UE 2 and UE 3 to send the first SRS.

[0309] Optionally, the network device learns, based on the first capability information reported by UE 1, that the maximum number of symbols that UE 1 can track in a slot is L, where L is an integer greater than or equal to 1. Thus, if UE 2 and UE 3 multiplex the same slot to send the first SRS, the network device may configure the UE 2 to send the first SRS in the slot using a maximum of L1 symbols, and configure the UE 3 to send the first SRS in the slot using a maximum of L2 symbols, where L1+L2 is less than or equal to L. Of course, when L1 characters overlap L2 characters, L1+L2 can be greater than L, provided that L1 is guaranteed to be less than or equal to L and L2 to be less than or equal to L. Similarly, when UE 2 and UE 3 do not send the first SRS in the same slot, it can also be ensured that the maximum number of symbols used to send the first SRS in the slot does not exceed the number of symbols that UE 1 can keep track of.

[0310] Optionally, the network device learns, based on the first capability information reported by UE 1, the maximum number of consecutive symbols that UE 1 can track in a slot. Thus, the number of consecutive symbols that are configured by the network device for UE 2 or UE 3 and which are used to send the first SRS is less than or equal to the maximum number of consecutive symbols.

[0311] Optionally, the number of first SRSs that can be monitored by the first terminal per time unit may include the number of first SRSs that can be monitored in the first time unit and the number of first SRSs that can be monitored in the second time unit. When the first time unit is a slot and the second time unit is a duration (where the duration is X slots and X is a positive integer), the network device learns, based on the first capability information reported by UE 1, that the number of first SRSs that can monitored by UE 1 in a slot is R, and the number of first SRSs that can be monitored in X slots is S. R is an integer greater than or equal to 1, and S is an integer greater than or equal to 1. Thus, the network device configures the number of first SRSs that can originate from the second terminal in a slot to be less than or equal to R, and the network device configures the number of first SRSs that can originate from the second terminal in X slots to be less than or equal to S. For example, if the number of first SRSs UE 1 can monitor in a slot is 8, the number of first SRSs that can be sent in X slots is 32, and UE 2 and UE 3 multiplex the slot, the network device can configure instruct UE 2 to send a maximum of the first two SRSs in the slot, and the network device configures the UE 3 to send a maximum of the first six SRSs in the same slot; and the network device may configure the UE 2 to send a maximum of the first eight SRSs in X slots, and the network device configures the UE 3 to send a maximum of the first 24 SRSs in the X same slots. Alternatively, if UE 2 and UE 3 do not send the first SRS in the same slot, the network device may configure UE 2 to send a maximum of the first eight SRS in the slot, and the network device configure UE 3 to send a maximum of the first eight SRS in the same slot. Alternatively, if UE 2 and UE 3 do not send the first SRS in X same slots, the network device may configure UE 2 to send a maximum of 32 first SRS in X slots, and the network device configure UE 3 to send a maximum of 32 first SRS in the other group x slots. Thus, regardless of whether UE 2 and UE 3 multiplex the same slot to send the first SRS, UE 2 or UE 3 sends a maximum of eight first SRS in a slot, which does not exceed the upper limit of the number of first SRS monitored by UE 1 in slot. Regardless of whether UE 2 and UE 3 multiplex X the same slots to send the first SRS, in X slots, UE 2 or UE 3 sends a maximum of 32 first SRS, which does not exceed the upper limit of the number of first SRS monitored by UE 1 in X slots.

[0312] In some other embodiments, the network device may not configure the first SRS of the second terminal based on the first capability information reported by the first terminal. For example, the network device configures the first SRS of the second terminal based on the decision of the network device.

[0313] In some other embodiments, the network device does not configure transmission or reception of data on one or more symbols before or after the symbol used to receive the first SRS (i.e., the SRS used for CLI measurement) so that the terminal can perform proper rate negotiation . Of course, alternatively, the symbol may be configured in a different way and some bits are repeated or punctured to implement rate matching.

[0314] In general, distances between different interfering terminals (namely, second terminals) and an interfering terminal (namely, first terminal) are different, so that the time at which the first SRSs of different second terminals arrive at the first terminal may not coincide. When the interval between cyclic shifts (CS) of the first two SRSs is relatively short, it is difficult for the first terminal to distinguish between the specific second terminals from which the first two SRSs respectively come, and furthermore, it is difficult to determine the specific sources of interference.

[0315] To solve the above problem, in some other embodiments, when the resources of the two second terminals are the same, the root sequences of the first SRSs of the two second terminals are different. That the resources of the two second terminals are the same may mean that one or more of the time domain resources, the frequency domain resources, or the spatial domain resources of the two second terminals are the same. Thus, different first SRSs can be distinguished based on different root sequences, and specific second terminals from which different first SRSs respectively come from can be determined to accurately determine interference sources.

[0316] In some other embodiments, when the resources of the two second terminals are the same, the root sequences of the first SRSs of the two second terminals are the same, and the difference between the cyclic shifts of the first SRSs of the two second terminals is a first offset value.

[0317] Optionally, the first offset value can be represented as . - the maximum number of cyclic shifts when the first SRS is configured. The maximum number of cyclic shifts may be 12 or 8, or another predetermined value.

[0318] Optionally, the first offset value may alternatively be configured as a different format parameter. In a sense, the first offset value can be set based on the SRS port configuration. The SRS port can be understood as an antenna port for sending SRS. When the SRS port is configured differently, the first offset value changes accordingly. In another way, the first offset value may be set based on a symbol interval, or may be set based on the relative distance between UEs.

[0319] In particular, the first offset value is U* . U - adjustable parameter. For example, U represents the number of SRS ports; in this case U is a positive integer. Of course, alternatively, U could be a parameter related to the number of SRS ports. For example, U may be calculated based on the number of SRS ports according to the calculation rule. For example, U is the number of SRS ports. When the number of SRS ports is 1, the first offset value is . When the number of SRS ports is 2, the first offset value is 2* . Thus, when the first SRSs of different terminal devices that are at different distances from the receiving terminal device arrive at the receiving terminal device, if the difference between the CSs of the first SRSs is greater than or equal to the first offset value, it can be guaranteed that the receiving terminal device can learn the terminal devices from which the first SRS respectively come when the distances are different.

[0320] In some other embodiments, the difference between CS is less than or equal to the second offset value. Optionally, the second offset value can be represented as V* . V - adjustable parameter. When the first SRSs of different terminal devices that are at different distances from the receiving terminal device arrive at the receiving terminal device, if the difference between the CSs of the first SRSs is less than or equal to the second offset value, it can be ensured that the requirement for the difference between CSs is not very large, so a certain amount of SRS is available.

[0321] In some other embodiments, the OAM configures the first SRS of the second terminal based on the first capability information.

[0322] It should be noted that the execution sequence of S1101-S1105 is not limited in this embodiment of this application. For example, the first terminal may simultaneously report each piece of capability information. Alternatively, the first capability information may be reported first, and then the second capability information and the third capability information may be reported. The network device may send configuration information to the first terminal after receiving one or more pieces of capability information; or the network device may first deliver the configuration information to the first terminal and then receive one or more pieces of the first terminal's capability information. Alternatively, the configuration information is delivered directly to the first terminal even if one or more pieces of the first terminal's capability information is not received.

[0323] Generally, when a terminal communicates with a base station, time synchronization needs to be performed. In other words, the base station needs to know the particular reception circumstances under which information is received from the terminal or the particular circumstances when information is sent to the terminal; and the terminal device also needs to know the specific circumstances when information is received from the base station, or the specific circumstances when information is sent to the base station. This helps to receive or send information under the correct receiving or sending circumstances. Referring to FIG. 4, the time at which the base station sends the downlink message is used as a reference time, the uplink sending of the UE 1 should be performed d1/c earlier than the reference time, the downlink reception of the UE 1 should be performed d1/c later than the reference time, and d1 is the distance between UE 1 and base station 1. Similarly, for uplink send and downlink receive cases of UE 2, refer to the corresponding cases of UE 1. This facilitates time synchronization between the UE and the base station.

[0324] In the current technology for time synchronization in a CLI system, two solutions are provided. Solution 1: The terminal transmits the first SRS when transmitting a physical uplink shared channel (PUSCH), that is, the timing advance (TA) for transmitting the first SRS is equal to the TA value for transmitting PUSCH. Thus, although the uplink and downlink time synchronization may be performed, the transmission of the PUSCH and the transmission of the first SRS may occupy the same time-frequency resource, and therefore the terminal is likely to be unable to demodulate the PUSCH correctly, causing loss of payload data. . Solution 2: In this method, it is necessary to assume that UE 1 and UE 2 are very close to each other. Therefore, the distance d shown in FIG. 1a can be ignored. UE 2 sends the first SRS d2/c later than the reference time, and UE 1 detects the first SRS d1/c later than the reference time. In this method, UE 2 delays the send time by d2/c, which is equivalent to the symbol used to transmit the first SRS is also shifted back accordingly. For example, initially the first SRS is transmitted using the seventh symbol in the first slot. At the moment, the send time should be delayed by d2/c. Accordingly, the first SRS may be transmitted using the first symbol in the next slot (second slot). However, the first symbol in the second slot is likely to be configured to transmit a PUSCH. Therefore, a collision occurs in the symbol between the first SRS and the PUSCH, and it is undesirable for the terminal to demodulate the PUSCH.

[0325] In order to solve the above technical problem, an embodiment of this application further provides a time synchronization method. Referring to FIG. 5, the time synchronization method includes the following steps.

[0326] S501: The second terminal receives the first resource to send the first sounding reference signal SRS.

[0327] There is a correspondence between the first resource and the geographic location information of the second terminal. The plurality of pieces of geographic location information respectively correspond to the plurality of first resources. When the second terminal is located in different geographic locations, the first resources used by the second terminal to send the first SRS are different. In an exemplary implementation, the predetermined geographic area may be divided into P (P is a positive integer) sub-regions. Each subdomain corresponds to one piece of geographic location information. The geographic location information may be, for example, an identifier, a code, or a sub-area number. P may be pre-configured in the terminal or configured by a network device. Different pieces of geographic location information correspond to different resources.

[0328] The first resource may be a time domain resource, a frequency domain resource, a spatial domain resource, a code domain resource, or the like. The type of the first resource is not specifically limited in this embodiment of this application. According to different pieces of geographic location information, that the second terminal sends the first SRS using different resources means that the second terminal sends the first SRS using different time domain resources, sends the first SRS using different frequency domain resources, sends the first SRS using different spatial domain resources, or sends the first SRS using different code domain resources. For example, a resource is a time domain resource. When the second terminal is located in sub-area 1, the first SRS is based on the use of the sixth symbol in the slot; when the second terminal is located in sub-area 2, the first SRS is based on the use of the seventh symbol in the slot. For example, a resource is a spatial domain resource. When the second terminal is located in sub-area 1, the first SRS is based on the use of the first antenna port; when the second terminal is located in sub-area 2, the first SRS is based on the use of the second antenna port.

[0329] Optionally, the first resource is a resource pre-configured in the terminal. In other words, the first resource is a resource preconfigured based on the geographic location information of the second terminal. For example, the correspondence between the resource and the geographic location information is pre-configured in the terminal. Thus, when sending the first SRS, the second terminal may request a match and, based on the match, determine the specific resource to be used to send the first SRS at the current geographic location.

[0330] Optionally, the second terminal receives an SRS configuration message from the network device, where the SRS configuration message indicates a first resource corresponding to the geographic location information of the second terminal. In particular, the network device indicates the first resource to the second terminal in at least one of the following ways.

[0331] Method 1: The SRS configuration message is a broadcast message. In particular, the network device periodically sends a broadcast message. The second terminal receives a broadcast message from the network device and determines, based on the broadcast message, a resource that can be used to send the first SRS at the current geographic location. The broadcast message conveys the correspondence between the geographic location information and the resource. Correspondence may include a relationship between a plurality of pieces of geographic location information and a plurality of resources. For example, the correspondence could be: {geographic location information 1 - resource 1; location information 2 - resource 2; ...; location information Q - resource Q}. Of course, the correspondence could alternatively be in a different format, such as a table format. The conformance format is not limited in this embodiment of this application. The second terminal receives and stores the match. Subsequently, when the second terminal needs to send the first SRS, the second terminal requests a match to learn about a resource corresponding to the current geographic location, and sends the first SRS using the corresponding resource.

[0332] Method 2: Before sending the first SRS, the second terminal sends an SRS resource request to the network device, where the SRS resource request is used to request the first resource to send the first SRS.

[0333] Optionally, as in case 2, the SRS resource request of the second terminal includes information about the current geographic location of the second terminal. Thus, the network device configures the corresponding first resource for the second terminal based on the current geographic location information of the second terminal, and sends an SRS configuration message to the second terminal to indicate the first resource corresponding to the current geographic location of the second terminal.

[0334] Alternatively, the SRS resource request from the second terminal may not contain information about the second terminal's current geographic location. Upon receiving the SRS resource request from the second terminal, the network device first determines the current geographic location of the second terminal, and then configures the first resource for the second terminal based on the current geographic location.

[0335] The second terminal can obtain the current geographic location of the second terminal using the following method: The network device sends a second reference signal to the second terminal; and after receiving the second reference signal, the second terminal obtains the second RSRP corresponding to the second reference signal, and obtains the geographic location information of the second terminal based on the second RSRP. The second RSRP indicates the receive power of the second reference signal applied to the second terminal. Alternatively, after receiving the second reference signal, the second terminal receives a second RSRQ corresponding to the second reference signal and obtains the geographic location information of the second terminal based on the second RSRQ. The second RSRQ indicates the signal quality of the second reference signal input to the second terminal.

[0336] The network device can obtain the current geographic location of the second terminal using the following method: The network device sends a second reference signal to the second terminal; and after receiving the second reference signal, the second terminal obtains the second RSRP corresponding to the second reference signal and sends the second RSRP to the network device. Thus, the network device obtains the geographic location information of the second terminal based on the received second RSRP. Alternatively, after receiving the second reference signal, the second terminal receives a second RSRQ corresponding to the second reference signal and sends the RSRQ to the network device. Thus, the network device obtains the geographic location information of the second terminal based on the received second RSRQ.

[0337] Of course, the second terminal or network device may alternatively determine the second terminal's current geographic location in another manner. This application is not limited.

[0338] S502: The second terminal sends the first SRS using the first resource.

[0339] Accordingly, the first terminal receives the first SRS from the second terminal.

[0340] Optionally, the first terminal may alternatively send fourth capability information (which may also be referred to as measurement accuracy capability) to the network device. The fourth capability information indicates the accuracy requirements of the measurement result. That the accuracy requirement is high means that it is indicated that the measurement result obtained by the first terminal of the first SRS is within the preset offset range; that the accuracy requirement is low means that the measurement result obtained by the first terminal of the first SRS may not be within the preset offset range. It is easy to understand that if the accuracy requirements are high, the network device performs the configuration based on the fourth capability information. For example, the network device instructs the first terminal to: execute the next step S503 and the subsequent procedure to adjust the reception timing (timing) and receive the first SRS under the right circumstances to ensure that the measurement result of the first SRS is more accurate. If the accuracy requirement is low, the first terminal may not perform the next receive timing adjustment step.

[0341] Of course, alternatively, the first terminal may determine, based on the accuracy requirement of the measurement result, whether to execute the next step S503 and the subsequent procedure.

[0342] S503: The first terminal determines the time offset based on the first resource.

[0343] In a possible implementation, as shown in FIG. 6, step S503 may be concretely implemented as the following steps.

[0344] S5031: The first terminal obtains the geographic location information of the second terminal based on the first resource.

[0345] It was mentioned above that there is a correspondence between the first resource and the geographic location information. Based on the match, the first terminal may determine the geographic location information of the second terminal based on the first resource to send the first SRS. The correspondence may be preconfigured in the first terminal. For example, the correspondence could be: {geographic location information 1 - resource 1; location information 2 - resource 2; ...; location information Q - resource Q}. Of course, the mapping may be stored on a device other than the network device (eg, a base station). When the first terminal needs to request a match, the first terminal obtains a match from the device storing the match. The specific implementation in which the first terminal obtains the geographical location information of the second terminal is not limited to this embodiment of this application. For example, the first terminal receives by monitoring the first SRS from the second terminal, where the first SRS is sent on the sixth symbol in the slot. In this case, the first terminal may determine the geographic location of the second terminal based on the match.

[0346] S5032: The first terminal obtains the first distance based on the geographic location information of the first terminal and the geographic location information of the second terminal, where the first distance is the distance between the first terminal and the second terminal.

[0347] For the manner in which the first terminal acquires the geographic location information of the first terminal, refer to the manner in which the second terminal acquires the geographic location information of the second terminal. Details are not described here again.

[0348] S5033: The first terminal obtains a time offset based on the first distance.

[0349] Referring to FIG. 4, an example is used in which the first terminal is UE 1 and the second terminal is UE 2, and the distance between UE 1 and UE 2 is d. In this case, the time offset can be calculated using the following formula: t=d/c, where t is the time offset, c is the radio signal propagation speed, and / is the division operator.

[0350] S504: Adjust, based on the time shift, the time at which the first SRS will be received.

[0351] In other words, when the reception circumstances are adjusted, the influence of the first distance between the first terminal and the second terminal can be taken into account. Optionally, with reference to FIG. 4, UE 2 sends the first SRS d2/c before the reference time, and UE 1 detects the first SRS (d1-d)/c after the reference time. The difference between the send case of UE 2 and the case of detection (reception) of UE 1 is (d2+d1-d)/c.

[0352] Of course, UE 2 may alternatively send the first SRS in another case. In this case, as long as the difference between the receiving case of UE 1 and the sending case of UE 2 is (d2+d1-d)/c, it can be guaranteed that the signal strength measured by UE 1 of the first SRS is close to the signal peak of the first SRS, and hence the accuracy of the measurement result is improved.

[0353] S505: Receive the first SRS at the time that is obtained after the adjustment and at which the first SRS is received.

[0354] According to the communication method provided in this embodiment of this application, the first terminal determines the time offset based on the first resource to send the first SRS of the specific second terminal, and adjusts, based on the time offset, the time at which the first SRS is received. Thus, the first terminal receives the first SRS at the time obtained after the adjustment. Since the first SRS can be received at a relatively accurate time, the measured signal strength of the first SRS can be closer to the peak of the first SRS signal, so that the measurement result representative of the first SRS is more accurate.
