Description

Method and device for sending uplink control information

This application claims priority to the Chinese patent application filed with the State Intellectual Property Office of China on February 15, 2023, with application number 202310150125.1 and application name “Method and device for sending uplink control information”, all contents of which are incorporated by reference in this application.

Technical Field

The present application relates to the field of communications, and in particular to a method and device for sending uplink control information in the field of communications.

Background Art

In recent years, with the continuous development of the fifth generation (5G) communication system, data transmission delay has been continuously reduced, and the transmission capacity has become larger and larger. 5G communication systems have gradually infiltrated some multimedia services with strong real-time requirements and large data capacity requirements, such as video transmission and extended reality (XR), among which XR includes virtual reality (VR) and augmented reality (AR). The data packets of XR services can arrive at the buffer of the sending device at a fixed frequency (for example, 60 Hz, 90 Hz, 120 Hz) to wait for transmission, which can also be understood as having a fixed arrival period (for example, when the fixed frequency is 60 Hz, the arrival period is 16.67 milliseconds (ms)). XR services have service requirements of ultra-high bandwidth and ultra-low latency.

With the rapid increase in communication transmission rates, real-time video transmission services have gradually become one of the core services in the current network. Cloud virtual reality (cloud VR) and augmented reality (cloud AR) introduce the concepts and technologies of cloud computing and cloud rendering into VR/AR business applications. With the help of high-speed and stable networks, the display output and sound output in the cloud are encoded and compressed and transmitted to the user equipment (UE), realizing the cloud-based VR/AR business content and rendering. VR/AR terminal devices can also meet the requirements of lightweight and mobility. The typical remote communication model scenario is shown in Figure 1.

Large data transmission volume is a very important requirement of mobile communications in 5G. For example, the network uplink rate required to meet the initial experience of interactive AR services is about 2Mbps, while 10-20Mbps is required to meet the advanced experience, otherwise people will feel stuck. The main feature of these services is that they require a higher uplink transmission rate.

Time domain repetition is a typical configuration method for the physical uplink shared channel (PUSCH). For communication services with large data volumes and dynamic changes, the method of configuring multiple PUSCHs within one configured grant (CG) period is usually adopted. However, this method may lead to a waste of PUSCH transmission resources.

Summary of the invention

The present application provides a method and device for sending uplink control information (UCI), which can reduce the waste of some PUSCH transmission resources and the signaling overhead of UCI.

In the first aspect, a communication method is provided. The method provided in the first aspect can be executed by a terminal device, or by a module applied to the terminal device (such as a processor, chip, or chip system, etc.), or by a logical node, logical module or software that can implement all or part of the terminal device functions. This application does not limit this.

Specifically, the method includes sending a first UCI at a first configured authorized CG transmission opportunity, the first UCI being used to indicate a second CG transmission opportunity carrying a second UCI, the first CG transmission opportunity and the second CG transmission opportunity being within a first CG cycle period; and sending the second UCI at the second CG transmission opportunity.

In one possible implementation, the UCI may indicate the remaining unused CG transmission opportunities within the CG cycle period.

In another possible implementation, the first UCI is sent at the first CG transmission opportunity, and the first UCI can also be used to indicate that the second UCI is no longer sent.

The method for sending uplink control information UCI in an embodiment of the present application can reduce the sending of unnecessary UCI by using UCI to indicate the CG transmission timing carrying another UCI, thereby saving signaling overhead.

In this application, the configuration of the authorized CG transmission timing may also be referred to as the timing, CG timing, transmission timing, CG PUSCH transmission, or PUSCH transmission timing, etc. This application does not limit this.

Optionally, the first CG transmission opportunity and the second CG transmission opportunity may be within one CG cycle period or within multiple CG cycles. This application does not impose any restrictions on this period.

For example, the first UCI may indicate the location of the CG transmission opportunity, or indicate the number of CG transmission opportunities.

In combination with the first aspect, in certain implementations of the first aspect, the first UCI is used to indicate the number N of CG transmission opportunities that are not used in the first CG cycle period, and N is greater than or equal to 0.

First, the application scenario of the present application is introduced. FIG1 shows a possible, non-limiting system schematic diagram.

As shown in FIG. 1 , the communication system 10 includes a radio access network (RAN) 100 and a core network (CN) 200. The RAN 100 includes at least one RAN node (such as 110a and 110b in FIG. 1 , collectively referred to as 110) and at least one terminal (such as 120a-120j in FIG. 4 , collectively referred to as 120). The RAN 100 may also include other RAN nodes, such as wireless relay equipment and/or wireless backhaul equipment (not shown in FIG. 1 ). The terminal 120 is connected to the RAN node 110 in a wireless manner. The RAN node 110 is connected to the core network 200 in a wireless or wired manner. The core network device in the core network 200 and the RAN node 110 in the RAN 100 may be different physical devices, or may be the same physical device that integrates the core network logical function and the radio access network logical function.

RAN 100 may be a cellular system related to the third generation partnership project (3GPP), for example, a 4G, 5G mobile communication system, or a future evolution system (for example, a 6G mobile communication system). RAN 100 may also be an open access network (open RAN, O-RAN or ORAN), a cloud radio access network (cloud radio access network, CRAN), or a wireless fidelity (wireless fidelity, WiFi) system. RAN 100 may also be a communication system that integrates two or more of the above systems.

The RAN node 110, which may also be sometimes referred to as an access network device, a network device, a RAN entity or an access node, etc., constitutes a part of the communication system to help the terminal achieve wireless access. The multiple RAN nodes 110 in the communication system 10 may be nodes of the same type or nodes of different types. In some scenarios, the roles of the RAN node 110 and the terminal 120 are relative. For example, the network element 120i in FIG. 1 may be a helicopter or a drone, which may be configured as a mobile base station. For the terminal 120j that accesses the RAN 100 through the network element 120i, the network element 120i is a base station; but for the base station 110a, the network element 120i is a terminal. The RAN node 110 and the terminal 120 are sometimes referred to as communication devices. For example, the network elements 110a and 110b in FIG. 1 may be understood as communication devices with base station functions, and the network elements 120a-120j may be understood as communication devices with terminal functions.

In a possible scenario, the RAN node may be a base station, an evolved NodeB (eNodeB), an access point (AP), a transmission reception point (TRP), a next generation NodeB (gNB), a next generation base station in a 6th generation (6G) mobile communication system, a base station in a future mobile communication system, or an access node in a WiFi system. The RAN node may be a macro base station (such as 110a in FIG. 1 ), a micro base station or an indoor station (such as 110b in FIG. 1 ), a relay node or a donor node, or a wireless controller in a CRAN scenario. Optionally, the RAN node may also be a server, a wearable device, a vehicle or an onboard device, etc. For example, the access network device in the vehicle to everything (V2X) technology may be a road side unit (RSU). All or part of the functions of the RAN node in the present application may also be implemented by software functions running on hardware, or by virtualization functions instantiated on a platform (such as a cloud platform). The RAN node in the present application may also be a logical node, a logical module or software that can implement all or part of the RAN node functions.

In another possible scenario, multiple RAN nodes collaborate to assist the terminal in achieving wireless access, and different RAN nodes implement part of the functions of the base station respectively. For example, the RAN node can be a central unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU). The CU and DU can be set separately, or can also be included in the same network element, such as a baseband unit (BBU). The RU can be included in a radio frequency device or a radio frequency unit, such as a remote radio unit (RRU), an active antenna unit (AAU) or a remote radio head (RRH).

The RAN node may also be expressed in different ways, such as network equipment. Unless otherwise specified in the following description of this application, network equipment is used for expression.

In different systems, CU (or CU-CP and CU-UP), DU or RU may also have different names, but those skilled in the art can understand their meanings. For example, in the ORAN system, CU may also be called O-CU (open CU), DU may also be called O-DU, CU-CP may also be called O-CU-CP, CU-UP may also be called O-CU-UP, and RU may also be called O-RU. For the convenience of description, this application takes CU, CU-CP, CU-UP, DU and RU as examples for description. Any unit of CU (or CU-CP, CU-UP), DU and RU in this application may be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

The terminal may also be referred to as a terminal device, user equipment (UE), mobile station, mobile terminal, etc. The terminal can be widely used in various scenarios, for example, device-to-device (D2D), vehicle-to-everything (V2X) communication, machine-type communication (MTC), Internet of Things (IOT), virtual reality, augmented reality, industrial control, automatic driving, telemedicine, smart grid, smart furniture, smart office, smart wear, smart transportation, smart city, etc. The terminal may be a mobile phone, a tablet computer, a computer with wireless transceiver function, a wearable device, a vehicle, a drone, a helicopter, an airplane, a ship, a robot, a mechanical arm, a smart home device, etc. The embodiments of the present application do not limit the device form of the terminal.

Unless otherwise specified in this application, terminal devices are used for representation.

The execution entities involved in the embodiments of the present disclosure include but are not limited to: terminal equipment (UE, user equipment), and network equipment, etc.

The following explains some concepts involved in a method and device for sending uplink control information (UCI) provided in an embodiment of the present application.

Taking the fifth generation (5G) new radio (NR) technology as an example, the present application is not limited to this. The transmission methods of PUSCH in NR include the following.

The first type is PUSCH transmission based on dynamic scheduling: when transmitting PUSCH, the transmission of PUSCH is scheduled by downlink control information (DCI). That is, after the terminal device receives the DCI scheduling, it can perform PUSCH transmission.

The second type is PUSCH transmission based on configured grant (CG) type 1: This is a semi-statically scheduled PUSCH. During the uplink transmission, the uplink scheduling resources configure the relevant parameters of CG transmission through the radio resource control layer (RRC) signaling, such as CG periodicity, CG time domain and frequency domain resources, etc. At the same time, the corresponding CG resources are activated through RRC signaling. The terminal device does not need to receive DCI and can periodically reuse the same time and frequency resources for uplink transmission.

The third type is PUSCH transmission based on configuration authorization type 2: the terminal device receives high-level configuration, and the semi-continuous time-frequency resources configured by the high-level are used for the terminal device to select and use, and these semi-continuous time-frequency resources are activated or deactivated by DCI. If the DCI indicates activation, the terminal device uses the semi-continuous time-frequency resources to send PUSCH according to its own data transmission needs, which is similar to the second PUSCH transmission method. After the transmission resource is activated by DCI, the network device can also deactivate the transmission resource through DCI, and the deactivated transmission resource will not be used by the terminal device for data transmission. It should be understood that uplink periodic service transmission can be based on configuration authorization CG or configured scheduling (CS).

CG resource configuration:

In an embodiment of the present application, the network device may configure at least one set of CG resource configurations for the terminal device. The parameters of a set of CG resource configurations may include at least one of the following: (1) the duration of the CG period; (2) the number of CG transmission opportunities included in a CG period, or the number of CG resources included in a CG period; (3) the time-frequency position information of each CG resource in a CG period. Among them, a CG period may include one or more CG resources. The multiple CG resources included in a CG period can be used to transmit data or transport blocks (TB), and the data transmitted by the multiple CG resources can be the same or different. The frequency domains of the multiple CG resources included in a CG period are the same, or repeated.

Figure 2 is a schematic diagram of PUSCH transmission based on the configuration authorization CG.

During uplink transmission, after uplink scheduling resources are allocated through radio resource control layer signaling or downlink control information, the same time-frequency resources can be periodically reused for uplink transmission, as shown in FIG2 .

In one implementation, a set of CG resource configuration parameters may also include other possible information, such as one or more of the following parameters of PUSCH: frequency hopping indication information (used to indicate frequency hopping within a time slot or between time slots), DMRS configuration information (used to indicate the type, position, length, and/or whether the demodulation reference signal (DMRS) is precoded, etc.), modulation and coding scheme (MCS) table, resource allocation method (which can be type 0 (type0), type 1 (type1) or dynamically switched resource allocation method), power control indication information, hybrid automatic repeat request (HARQ) process number (for example, it can be one of 1 to 16), etc., without specific limitation.

CG transmission occasion (TO):

The CG transmission opportunity may also be referred to as occasion, CG occasion, transmission opportunity, CG PUSCH transmission, or PUSCH transmission opportunity, etc. This application does not limit this.

The CG transmission opportunity includes a time domain resource for transmitting data once, such as a time slot, a subframe, or a mini-slot, etc. The length of the above mini-slot can be one or more symbols (for example, 1 symbol, 2 symbols, or 4 symbols, etc.).

The CG transmission opportunity can be used for the terminal device to send uplink information to the network device. The uplink information may include uplink data and/or uplink signaling. The uplink signaling may include at least one of the following: signaling of the physical layer, signaling of the media access control (MAC) layer, and signaling of the RRC layer. These uplink data and/or uplink signaling may be carried on the PUSCH specific to the terminal device.

In one possible implementation, a CG transmission opportunity may correspond to part of the CG resources in a CG cycle.

In addition, in the embodiments of the present application, the word "exemplary" is used to indicate an example, illustration or description. Any embodiment or design described as "exemplary" in the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the word "exemplary" is used to present concepts in a concrete way.

The network architecture and service scenarios described in the embodiments of the present application are intended to more clearly illustrate the technical solutions of the embodiments of the present application. This constitutes a limitation of the technical solution provided in the embodiments of the present application. Those skilled in the art may appreciate that, with the evolution of network architecture and the emergence of new business scenarios, the technical solution provided in the embodiments of the present application is also applicable to similar technical problems.

Some scenarios in the embodiments of the present application are explained by taking the scenarios of the NR network in the wireless communication network as an example. It should be pointed out that the solutions in the embodiments of the present application can also be applied to other wireless communication networks, and the corresponding names can also be replaced by the names of corresponding functions in other wireless communication networks.

The uplink control information in NR involves the following basic concepts.

It should be understood that when multiple PUSCHs are configured in a CG cycle, the UCI can be used to indicate the remaining unused CG transmission opportunities in the CG cycle, so that the network equipment can allocate the remaining unused CG transmission resources to other users in advance for uplink transmission, thereby improving the uplink transmission capacity.

As shown in Figure 3, Figure 3 is a schematic diagram of multiple PUSCH transmissions based on the configuration authorization CG. Exemplarily, three CG cycle periods are shown in the figure, wherein each CG cycle period is configured with three PUSCHs for uplink data transmission. In the first CG cycle period, one PUSCH is occupied for data transmission, and the number of unused CG transmission opportunities remaining in the CG cycle period is 2; in the second CG cycle period, three PUSCHs are occupied for data transmission, and the number of unused CG transmission opportunities remaining in the CG cycle period is 0; in the third CG cycle period, no data transmission is performed, i.e., no PUSCH resources are occupied.

It should be understood that UCI can be carried and sent on the PUSCH channel, and this application does not limit this.

For video services, the basic processing is to divide the video into N pictures per second, and encode each picture as a video frame. Each video frame can be encoded in terms of color, brightness, etc. to form digital information. However, since each video frame contains more pixels, the size of the encoded digital information is quite large, and the transmission will occupy a lot of bandwidth. The network uplink rate required to meet the initial experience of interactive AR services is about 2Mbps, and 10-20Mbps is required to meet the advanced experience.

In addition, for XR transmission services and video services, their business models are usually based on the periodic arrival of frame rates. For example, for a video with a frame rate of 60 frames per second (FPS), ideally, a picture frame arrives every 16.67 milliseconds, and the size of each video frame is usually variable. Due to the different compression rates and frame types of each video frame, the size of each video frame varies greatly.

Since each video frame has a large amount of data, the data packet of a video frame will be divided into dozens of IP packets (internet protocol, IP) for transmission. Due to the delay of video encoding, the IP packets of the same video frame will be widened in the time domain (burst length, BL). Different frame sizes and different terminal encoding capabilities will result in different BL ranges and different IP packet sizes. Intuitively, BL will make it possible for a frame's data packet to arrive in multiple time slots.

In order to reduce the waste of CG transmission resources and obtain the remaining available CG transmission opportunities within the CG cycle period, the terminal device needs to send UCI at each CG transmission opportunity within the CG cycle. However, since the code rate used for UCI multiplexing to PUSCH is low, sending UCI at each CG transmission opportunity will cause a waste of resources and a high decoding complexity.

In view of the above problems, the present application proposes a method for sending uplink control information, which can reduce the waste of some PUSCH transmission resources and the signaling overhead of UCI.

FIG. 4 is a schematic diagram of the stretching of a data packet when multiple PUSCHs are transmitted.

Exemplarily, as shown in FIG4 , FIG4 shows a CG cycle period, wherein data uplink transmission can be performed through 7 PUSCHs during the CG cycle period. Since each IP packet in the data packet of the same video frame will be widened in the time domain, the data of a video frame data packet in the figure arrives at the first four CG transmission opportunities in the cycle, wherein the black square represents a subpacket that needs to occupy a PUSCH resource, and the amount of data that needs to be uploaded at each CG transmission opportunity in the first four CG transmission opportunities may also be different. For example, in FIG4 , two subpackets arrive at the first CG transmission opportunity, no subpacket arrives at the second CG transmission opportunity, one subpacket arrives at the third CG transmission opportunity, and two subpackets arrive at the fourth CG transmission opportunity, so the data packet needs to occupy a total of 5 PUSCHs for data uplink transmission during the CG cycle period.

It should be understood that the terminal device generally cannot determine the arrival of the sub-packet of the subsequent CG transmission opportunities at the first CG transmission opportunity within a CG cycle period.

Fig. 5 is a flow chart of a method for sending information according to an exemplary embodiment. The method can be applied to the communication system shown in Fig. 1, but the embodiment of the present application does not limit this.

It is understood that the schematic diagram of the method in this application uses the network device and the terminal device as the execution subject of the interactive diagram as an example to illustrate the method, but this application does not limit the execution subject of the interactive diagram. For example, the network device in the figure can also be a module (such as a chip, a chip system, or a processor) applied to the network device, or a logical node, a logical module, or software that can implement all or part of the functions of the network device; the terminal device in the figure can also be a module (chip, chip system, or processor) applied to the terminal device, or a software that can Logical nodes, logic modules or software that implement all or part of the terminal device functions.

The method 500 comprises the following processing steps:

S510, the terminal device sends a first UCI, and correspondingly, the network device receives the first UCI, the first UCI is used to indicate a second CG transmission opportunity that carries a second UCI, and the first CG transmission opportunity and the second CG transmission opportunity are within a first CG cycle period.

S520, the terminal device sends a second UCI at the second CG transmission timing, and correspondingly, the network device receives the second UCI.

The information sending method of the embodiment of the present application sends a first UCI at a first CG transmission timing through a terminal device, and the first UCI is used to indicate a second CG transmission timing carrying a second UCI. At the same time, a network device receives the first UCI at the first CG transmission timing, and receives the second UCI at a second CG transmission timing according to the second CG transmission timing carrying the second UCI indicated by the first UCI, thereby reducing the sending of unnecessary UCI in the first CG cycle period, thereby saving signaling overhead.

Optionally, the first CG transmission opportunity and the second CG transmission opportunity may be within one CG cycle period or within multiple CG cycle periods, which is not limited in this application.

The following describes in detail the implementation of each of the above steps.

Taking FIG. 4 as an example, possible indication modes adopted by the method for sending uplink control information of the present application are described below.

In Figure 4, taking the sending of the first UCI at the first CG transmission opportunity as an example, when the terminal device sends the first UCI at the first CG transmission opportunity, the first UCI indicates the second CG transmission opportunity carrying the second UCI, that is, the third CG transmission opportunity within the CG cycle period, and the terminal device sends the second UCI at the above third CG transmission opportunity.

For another example, in Figure 4, taking the sending of the first UCI at the third CG transmission opportunity as an example, when the terminal device sends the first UCI at the third CG transmission opportunity, the first UCI indicates the second CG transmission opportunity carrying the second UCI, that is, the fourth CG transmission opportunity in the CG cycle period, and the terminal device sends the second UCI at the above fourth CG transmission opportunity.

It should be understood that each CG transmission opportunity with the arrival of a sub-packet within a CG cycle period can be used as the first CG transmission opportunity for sending the first UCI, or the second CG transmission opportunity for carrying the second UCI, and this application does not limit this.

It should be understood that the first UCI is used to indicate the second CG transmission opportunity carrying the second UCI, and this application does not limit the above indication method. For example, the first UCI can indicate the position of the CG transmission opportunity, or indicate the number of CG transmission opportunities.

For example, in Figure 4, the first UCI is sent at the first CG transmission opportunity, and the first UCI indicates the second CG transmission opportunity that carries the second UCI. The second CG transmission opportunity is the third CG transmission opportunity within the CG cycle period. When the first UCI indicates the position, the first UCI can be used to indicate that the second UCI is carried at the third CG transmission opportunity; when the first UCI indicates the quantity, the first UCI can be used to indicate the second CG transmission opportunity after the first CG transmission opportunity, that is, the third CG transmission opportunity that carries the second UCI.

Optionally, when the terminal device reports UCI for the first time within a CG cycle period, it can indicate that all CG transmission opportunities within the CG cycle period are used.

In a possible implementation, the original field and/or newly added field of UCI may be used to carry the above information. For example, the original field is reused on the basis of the existing UCI, and the field is used to indicate the second CG transmission timing carrying the second UCI.

Optionally, the original field may be a field indicating remaining unused CG transmission opportunities.

It should be understood that the above description is only exemplary. In actual applications, the above fields may also be new fields, and this application does not limit this.

The embodiments of the present application do not specifically limit the manner of representing the above information. For example, bit information or different numerical values may be used to indicate the position and/or number of the second CG transmission opportunities carrying the second UCI in the CG cycle period; or, the position and/or number of the second CG transmission opportunities carrying the second UCI in the CG cycle period may be indicated by text information.

Exemplarily, the UCI includes an original field 2, and the original field 2 can be used to indicate that the second CG transmission opportunity after the CG transmission opportunity where the UCI is located is the CG transmission opportunity for carrying the second UCI. Taking Figure 4 as an example, the first UCI is sent at the first CG transmission opportunity, and the field 2 in the first UCI indicates that the second CG transmission opportunity for carrying the second UCI is the second CG transmission opportunity after the first CG transmission opportunity, that is, the second UCI is carried at the third CG transmission opportunity.

Optionally, when the original field and/or the newly added field are used to indicate the position and/or number of the second CG transmission opportunities carrying the second UCI within the CG cycle period, the length of the original field and/or the newly added field is variable.

For example, when a new field is used to indicate the position of the second CG transmission opportunity carrying the second UCI within the CG cycle period, the number of CG transmission opportunities configured within the CG cycle period can correspond to the number of bits of the new field in the UCI. For example, if the number of CG transmission opportunities configured within a CG cycle period is 8, 3 bits of information can be used to indicate the position of the second CG transmission opportunity carrying the second UCI. This application does not limit this.

It should be understood that the more CG transmission opportunities are configured within a CG cycle period, the greater the number of bits required for the newly added field.

In this implementation, the field length can be flexibly configured according to requirements, which can save resources.

In another possible implementation manner of S510, the terminal device sends a first UCI, and correspondingly, the network device receives the first UCI, and the first UCI may be used to indicate that the second UCI is not to be sent.

It should be understood that in this implementation, S520 may be absent.

Optionally, in some embodiments, the first UCI may also indicate a CG transmission opportunity that is not used in the first CG cycle period, or indicate a CG transmission opportunity that is used in the first CG cycle period.

Taking Figure 4 as an example, for example, the first UCI is sent at the fourth CG transmission opportunity, and the first UCI indicates that the second UCI is not sent, that is, no UCI is sent in the CG cycle. By indicating that the second UCI is not sent at the first UCI sent at the fourth CG transmission opportunity, and indicating the CG transmission opportunity that is not used in the CG cycle, or the CG transmission opportunity that is used, the network device can allocate the remaining unused CG resources to other users for uplink transmission in advance, thereby improving the uplink transmission efficiency and saving signaling overhead.

Optionally, the terminal device can add tail packet information or tail packet identification to the data packet to clarify that all sub-packets have arrived within the current CG cycle period. The tail packet information may include the total number of sub-packets transmitted by the data packet, the total size of the long message and indication information, etc., which is not limited in this application. It is easy to understand that when the terminal device receives the tail packet of the data packet, it means that the data packet has been received.

Optionally, in some embodiments, when the first UCI indicates the position of a CG transmission opportunity, it may indicate that all CG transmission opportunities after the position of the CG transmission opportunity where the first UCI is located within the CG cycle period are not used.

Taking Figure 4 as an example, when the terminal device receives the tail packet information at the fourth CG transmission opportunity within the CG cycle period, it can send the first UCI at the fifth CG transmission opportunity, indicating that the second UCI will no longer be sent, that is, all CG transmission opportunities after the fifth CG transmission opportunity will not be used.

Exemplarily, the UCI may include one field 0, and the one field 0 is used to indicate that all CG transmission opportunities after the CG transmission opportunity where the UCI is located are not used, or that the UCI is no longer sent after the CG transmission opportunity where the UCI is located.

Optionally, the above information may be indicated by using original fields and/or newly added fields.

The embodiments of the present application do not specifically limit the manner in which the above information is represented. For example, different numerical values may be used to indicate the position of the second CG transmission opportunity that carries the second UCI in the first CG cycle period, or to indicate the CG transmission opportunity used in the first CG cycle period; or, a text message may be used to directly indicate a CG transmission opportunity that is not used in the first CG cycle period, or to indicate a CG transmission opportunity used in the first CG cycle period.

In a feasible implementation, the first UCI may also indicate a CG transmission opportunity that is not used in the first CG cycle period, or indicate a CG transmission opportunity that is used in the first CG cycle period.

In an embodiment of the present application, by indicating the second CG transmission opportunity carrying the second UCI and the remaining unused CG transmission opportunities within the CG cycle period, or indicating the CG transmission opportunities used within the CG cycle period, the network device can clearly identify the allocatable CG transmission opportunities, thereby improving the uplink transmission capacity.

It should be understood that when the first UCI indicates a CG transmission opportunity that is not used in the first CG cycle period, or indicates a CG transmission opportunity used in the first CG cycle period, it may include multiple implementation methods, and this application does not limit the above indication method. For example, the first UCI may indicate the location of the CG transmission opportunity, or indicate the number of CG transmission opportunities.

Taking Figure 4 as an example, for example, the first UCI is sent at the fourth CG transmission opportunity, and the first UCI indicates a CG transmission opportunity that is not used in the CG cycle period, or indicates a CG transmission opportunity that is used in the CG cycle period. When the first UCI indicates the position of the CG transmission opportunity, the CG transmission opportunity that is not used in the CG cycle period is the sixth and seventh CG transmission opportunities in the CG cycle period; the CG transmission opportunity used in the CG cycle period is the first to fifth CG transmission opportunities in the CG cycle period, or after receiving the tail packet, the first CG transmission opportunity among the remaining fifth to seventh CG transmission opportunities is used, that is, the sixth and seventh CG transmission opportunities are not used; when the first UCI indicates the number of CG transmission opportunities, different numerical values can be used to indicate the unused CG transmission opportunities, or the number of used CG transmission opportunities.

Optionally, the above information may be carried using original fields and/or newly added fields.

The embodiments of the present application do not specifically limit the manner in which the above information is represented. For example, different numerical values may be used to indicate CG transmission opportunities that are not used in the first CG cycle period, or to indicate CG transmission opportunities that are used in the first CG cycle period; or, text information may be used to directly indicate CG transmission opportunities that are not used in the first CG cycle period, or to indicate CG transmission opportunities that are used in the first CG cycle period.

It should be understood that the original fields and/or the newly added fields can be empty.

Optionally, the terminal device can add tail packet information or tail packet identification to the data packet to clarify that all sub-packets have arrived within the current CG cycle period. Taking Figure 4 as an example, at the fourth CG transmission opportunity within the CG cycle period, the terminal device can clearly All the data of the period has arrived, that is, UCI can be sent to indicate that the second UCI will no longer be sent, and to indicate the CG transmission timing that is not used in the CG period, or to indicate the CG transmission timing that is used in the CG period.

In this implementation, after the terminal device receives the tail packet information, it can send UCI to indicate that the second UCI will no longer be sent, and indicate the CG transmission opportunity that is not used in the CG cycle period, or indicate the CG transmission opportunity that is used in the CG cycle period, without sending additional UCI beyond the CG transmission opportunity occupied by the arrival of the data packet. This method enables the network equipment to have more time to allocate the remaining unused CG resources to other users for uplink transmission in advance, and has higher flexibility.

It should be noted that the configuration position of each field in the first UCI can be set as needed, for example, the original field and/or the newly added field can be configured in any field in the first UCI.

Specifically, the original field and/or the newly added field can be configured in the initial field of the first UCI, or the original field and/or the newly added field can be configured at any position in the middle of the first UCI, or the original field and/or the newly added field can be configured at the end position of the first UCI.

Optionally, when the original field and/or the newly added field are used to indicate the position and/or number of the second CG transmission opportunities carrying the second UCI within the CG cycle period, the length of the original field and/or the newly added field is variable.

Optionally, in some embodiments, the first UCI may be used to indicate the number N of CG transmission opportunities not used in the first CG cycle period, where N is greater than or equal to 0.

By implementing the above method and using the number N to indicate the CG transmission timing, the complexity of the first UCI can be reduced.

Optionally, in some embodiments, the N unused CG transmission opportunities are the last N CG transmission opportunities in the first CG cycle period.

By implementing the above method, it can be clearly stated that the allocatable CG transmission opportunities are the last N CG transmission opportunities in the first CG cycle period, which can improve resource allocation efficiency.

For example, when sending the first UCI at the first CG transmission opportunity, bit information may be used to indicate the second CG transmission opportunity carrying the second UCI indicated by the first UCI, and the number N of CG transmission opportunities not used in the first CG cycle period. For example, bit information is used to indicate the second CG transmission opportunity carrying the second UCI, wherein the position of the second CG transmission opportunity carrying the second UCI in the first CG cycle period is indicated by "000", "001", etc., and the number N of CG transmission opportunities not used in the first CG cycle period is indicated by "000", "001", etc.

For another example, the second CG transmission opportunity information carrying the second UCI indicated by the first UCI can be configured in a newly added field in the first UCI, and the number N of CG transmission opportunities not used in the first CG cycle period indicated by the first UCI can be configured in the original field in the first UCI.

Optionally, when the duration of the CG cycle is configured to be equal to the duration of multiple service cycles, the N unused CG transmission opportunities are the last N transmission opportunities within a period of time, and the period of time matches the duration of the service cycle.

It should be understood that the embodiments of the present application are not limited to the above-mentioned indication method.

It should be understood that when the second CG transmission opportunity carrying the second UCI is indicated by the first UCI, the terminal device may query at least one of the following information to determine the second CG transmission opportunity carrying the second UCI:

1. The capabilities of the terminal device;

2. The spread distribution of data packets in any CG period before the first CG period;

3. The type of data packet.

In one possible implementation, the transmission timing of the second CG carrying the second UCI may be determined according to the capability of the terminal device.

Specifically, the capabilities of the terminal device may include coding capabilities, coding methods, coding parameters, etc.

In another possible implementation, the second CG transmission timing carrying the second UCI may be determined based on the spread distribution of data packets in any CG cycle period before the first CG cycle period.

Taking Figure 6 as an example, the possible indication methods of indicating the CG transmission timing of the present application are explained below.

As shown in FIG. 6 , the first CG cycle period in the figure is used to transmit a data packet of the first frame, and its subpackets arrive in multiple time slots of the first CG cycle period, wherein two subpackets arrive at the first CG transmission opportunity of the first CG cycle period, no subpackets arrive at the second CG transmission opportunity, one subpacket arrives at the third CG transmission opportunity, and two subpackets arrive at the fourth CG transmission opportunity. When the terminal device transmits a data packet of the xth frame in the xth CG cycle period, at the first CG transmission opportunity of the xth CG cycle period, the CG transmission opportunity is used as the first CG transmission opportunity. The terminal device can determine that the second CG transmission opportunity is the third CG transmission opportunity in the CG cycle period according to the CG transmission opportunities at which different subpackets arrive in the above-mentioned first CG cycle period, and send the first UCI at the first CG transmission opportunity, indicating that the second CG transmission opportunity carrying the second UCI is the third CG transmission opportunity in the xth CG cycle period, that is, according to The spread distribution of data packets in the first CG cycle period determines the second CG transmission timing carrying the second UCI.

It should be understood that the above-mentioned indication method for CG transmission timing is only exemplary. In actual applications, the first CG cycle period can be any CG cycle period before the x-th CG cycle period, or any multiple CG cycle periods, or it can be the cycle period before the x-th CG cycle period. This application does not limit this.

In another possible implementation, the transmission timing of the second CG carrying the second UCI may be determined according to the type of the data packet.

Optionally, the data packet may be a data packet of a video frame, and the type of the data packet may be divided into a continuous video frame, a changing video frame, etc. according to the type of the video frame.

Specifically, continuous video frames refer to video frames that are the same or similar in color and content, such as video frames in a video in which an object does not change or changes continuously, and the content in these video frames does not change or changes partially. Therefore, the type of video frames included in the video is continuous video frames.

A changing video frame refers to a video frame in which the contents of different video frames change significantly when a shot switch or a scene switch occurs.

It should be understood that the above description of the types of video frames is only exemplary. In practical applications, video frames may also have other types, and the embodiments of the present application are not limited thereto.

In addition, in practical applications, other methods can be used to classify video frames into multiple types. For example, the types of video frames can include character video frames (e.g., video frames with character images), landscape video frames (e.g., video frames with landscapes)..., and the embodiments of the present application are not limited thereto.

Optionally, in some embodiments, the second CG transmission opportunity carrying the second UCI can be determined based on the number of subpackets arriving at the first CG transmission opportunity within the first CG cycle period.

It should be understood that the above description is only an example, and the embodiments of the present application are not limited thereto. The types of data packets can also be distinguished in other ways.

It should be understood that the terminal device can determine the transmission timing of the second CG carrying the second UCI by querying at least one of the above information, or arbitrarily combine the above information, or use the above information in any way, and this application does not limit this.

Optionally, in some embodiments, UCI may also indicate at least one of hybrid automatic repeat request acknowledgment (HARQ-ACK) information, channel state information (CSI) and other possible information.

Fig. 7 is a flow chart of another information sending method according to an exemplary embodiment. The method can be applied to the communication system shown in Fig. 1, but the embodiment of the present application does not limit this.

The method 700 includes the following processing steps:

S710: The terminal device generates a third UCI.

S720, the terminal device sends a third UCI at a third CG transmission timing, and correspondingly, the network device receives the third UCI at a third CG transmission timing, and the third UCI includes the first information and the second information.

When the first information indicates a first preset value, the second information indicates a fourth CG transmission opportunity for carrying a fourth UCI, and the third CG transmission opportunity and the fourth CG transmission opportunity are within a second CG cycle period.

In the information sending method of an embodiment of the present application, the terminal device sends a third UCI at a third CG transmission timing, and the third UCI includes second information. When the first information indicates a first preset value, the second information can indicate a fourth CG transmission timing for carrying a fourth UCI, thereby reducing the sending of unnecessary UCI and saving signaling overhead.

The following describes in detail the implementation of each of the above steps.

Taking FIG. 4 as an example, possible indication modes adopted by the method for sending uplink control information of the present application are described below.

In Figure 4, taking the generation of the third UCI at the first CG transmission opportunity as an example, when the terminal device generates the third UCI at the first CG transmission opportunity, the third UCI includes first information and second information. At this time, the first information indicates a first preset value, and the second information indicates the fourth CG transmission opportunity for carrying the fourth UCI, that is, the third CG transmission opportunity within the CG cycle period.

For another example, in Figure 4, taking the generation of the third UCI at the third CG transmission opportunity as an example, when the terminal device generates the third UCI at the third CG transmission opportunity, the third UCI includes first information and second information. At this time, the first information indicates a first preset value, and the second information indicates the fourth CG transmission opportunity for carrying the fourth UCI, that is, the fourth CG transmission opportunity within the CG cycle period.

It should be understood that each CG transmission opportunity with the arrival of a sub-packet within a CG cycle period can be used as a third CG transmission opportunity for sending a third UCI, or a fourth CG transmission opportunity for carrying a fourth UCI, and this application does not limit this.

The embodiment of the present application has no particular limitation on the representation method of the first preset value. For example, bit information can be used to indicate that the first information indicates the first preset value, such as using bit information to indicate the first preset value, where "0" indicates the first preset value, or Alternatively, the first preset value may be indicated by “1”; or, different numerical values may be used to indicate the first preset value; or, different symbols may be used to indicate the first preset value, such as “+” to indicate the first preset value, or “-” to indicate the first preset value; or, the first preset value may be directly indicated by text information.

In a possible implementation manner, the first information involved in the embodiment of the present application may be a newly added field or an original field in the third UCI.

Specifically, taking the first information being a newly added field in the third UCI as an example, if the first information is a newly added field in the third UCI, the third UCI may further include other fields, and these fields may be defined as needed.

It should be noted that the configuration position of the field of the first information in the third UCI can be set as needed, for example, a newly added field can be configured in any field in the third UCI.

Specifically, the newly added field may be configured in the initial field of the third UCI, or may be configured in any position in the middle of the third UCI, or may be configured in the end position of the third UCI.

It should be understood that when the second information indicates the fourth CG transmission opportunity for carrying the fourth UCI, the present application does not limit the above indication method. For example, the second information may indicate the location of the CG transmission opportunity, or indicate the number of CG transmission opportunities. Its implementation method can refer to the first implementation method and will not be repeated.

Optionally, when the original field and/or the newly added field are used to indicate the position and/or number of the fourth CG transmission opportunities carrying the fourth UCI within the CG cycle period, the length of the original field and/or the newly added field is variable.

Optionally, in some embodiments, when the first information indicates a second preset value, the second information is used to indicate a CG transmission opportunity that is not used in the second CG cycle period, or to indicate a CG transmission opportunity that is used in the second CG cycle period.

By implementing the above method, the allocatable CG transmission timing can be clarified, thereby improving the uplink transmission capacity.

It should be understood that the second preset value and the first preset value have different meanings. Specifically, for example, different numerical values or different symbols are used to indicate the first preset value and the second preset value, such as "+" indicates the first preset value, and "-" indicates the second preset value.

Optionally, 1 bit of information may be used to indicate the first preset value and the second preset value, wherein, if “0” indicates the first preset value, then “1” may indicate the second preset value. This embodiment of the present application does not limit this.

As an optional embodiment, the second preset value may be expressed in the same manner as the first preset value, or may be expressed in a manner different from the first preset value. The embodiment of the present application has no particular limitation on the manner in which the second preset value is expressed.

Optionally, the terminal device can add tail packet information or tail packet identification to the data packet to clarify that all sub-packets have arrived within the current CG cycle period. The implementation method can refer to the first implementation method and will not be repeated here.

Specifically, taking Figure 4 as an example, the indication method of the embodiment of the present application is exemplarily described. In the illustrated CG cycle period, taking the generation of the third UCI at the first CG transmission opportunity as an example, at the third CG transmission opportunity, that is, the first CG transmission opportunity mentioned above, the third UCI is sent, and the third UCI includes first information and second information. At the first CG transmission opportunity, the first information indicates a first preset value, and at this time, the second information indicates a fourth CG transmission opportunity for carrying a fourth UCI, and the fourth CG transmission opportunity is the third CG transmission opportunity within the CG cycle period.

For another example, within the CG cycle period shown in Figure 4, a third UCI is generated at the fourth CG transmission opportunity; the third UCI is sent at the third CG transmission opportunity, i.e., the fourth CG transmission opportunity mentioned above, and the third UCI includes first information and second information.

S810, the network device sends indication information within the third CG cycle period, the indication information is used to indicate the fifth CG transmission opportunity carrying the fifth UCI, the fifth CG transmission opportunity is within the third CG cycle period. Correspondingly, the terminal device receives the indication information within the third CG cycle period

In the information sending method of the embodiment of the present application, the network device sends indication information. By sending the indication information used to indicate the transmission timing of the fifth CG carrying the fifth UCI, the sending of unnecessary UCI can be reduced, which is beneficial to saving signaling overhead.

The following describes in detail the implementation of each of the above steps.

Optionally, in some embodiments, the network device may send indication information based on scheduling information, resource status information, context information, etc.

Optionally, in some embodiments, indication information may be used to indicate not to send UCI.

In another possible implementation of S810, the network device sends indication information within the third CG cycle period, and the indication information can be used to indicate not to send the fifth UCI.

It should be understood that in this implementation, S820 may be absent.

Taking Figure 4 as an example, for example, the network device can send indication information in the time slot interval between the fifth and sixth CG transmission opportunities within the CG cycle period, and the indication information indicates that the fifth UCI is not sent, that is, no UCI is sent within the CG cycle.

For another example, when the network device resources are sufficient, that is, no other users need to perform uplink transmission, the network device can instruct the terminal device not to send UCI through indication information.

Optionally, in some embodiments, when the resource status of the network device is insufficient, FIG. 4 is taken as an example below to illustrate possible indication methods used by the information sending method of the present application.

In Figure 4, exemplarily, the network device can send indication information in the time slot interval between the first and second CG transmission opportunities within the CG cycle period, and the indication information is used to indicate the fifth CG transmission opportunity carrying the fifth UCI. The fifth CG transmission opportunity within the CG cycle period can be the third CG transmission opportunity or any CG transmission opportunity after the indication information, and this application does not limit this.

Optionally, in some embodiments, the network device may send indication information after receiving UCI.

Optionally, in some embodiments, the K unused CG transmission opportunities are the last K CG transmission opportunities in the third CG cycle period.

By implementing the above method, it can be clearly stated that the allocatable CG transmission opportunities are the last K CG transmission opportunities in the third CG cycle period, which can improve resource allocation efficiency.

Optionally, when the duration of the CG cycle is configured to be equal to the duration of multiple service cycles, the K unused CG transmission opportunities are the last K transmission opportunities within a period of time, and the period of time matches the duration of the service cycle.

Optionally, in some embodiments, the UCI sent by the terminal device also includes prediction information, and the prediction information is used to indicate the next time to send indication information. For example, at the first CG transmission opportunity within a CG cycle period, the prediction information of the UCI sent by the terminal device can be The first CG transmission opportunity is the CG transmission opportunity required to upload data.

Taking Figure 4 as an example, the terminal device sends UCI at the first CG transmission opportunity of the illustrated CG cycle. The first CG transmission opportunity needs to upload 2 sub-packets, that is, it needs to occupy 2 CG transmission opportunities. In this case, the terminal device can indicate in the UCI prediction information sent that the network device can send indication information after 2 CG transmission opportunities. The prediction information can be used as a reference for the network device to send indication information.

Optionally, in some embodiments, the network device may send indication information based on prediction information, scheduling information, resource status information, context information, etc.

For example, the terminal device may query at least one of the following information to determine the prediction information used to indicate the indication information:

1. The capabilities of the terminal device;

2. Distribution of data packets in any CG period before the first CG period;

3. The type of data packet.

The implementation method thereof can refer to the first implementation method and will not be described in detail.

Optionally, in some embodiments, the terminal device can add tail packet information or tail packet identification to the data packet to clarify that all sub-packets have arrived within the current CG cycle period. Taking Figure 4 as an example, at the fourth CG transmission opportunity within the CG cycle period, the terminal device can clarify that all data of the current CG cycle has arrived, that is, send UCI to indicate that the second UCI will no longer be sent, and indicate the CG transmission opportunity that is not used within the CG cycle period, or indicate the CG transmission opportunity used within the CG cycle period.

Optionally, in some embodiments, the tail packet information may be indicated by UCI. For example, after receiving the tail packet information in the data packet, the terminal device may notify the network device of receiving the tail packet information by using UCI.

Optionally, in some embodiments, the tail packet information may be indicated by a medium access control-control element (MAC-CE). For example, after receiving the tail packet information in the data packet, the terminal device may notify the network device of receiving the tail packet information through MAC-CE.

Optionally, in some embodiments, when indicating the receipt of the tail packet information, multiple implementation methods may be included, and this application does not limit the above indication method. For example, the position of the CG transmission opportunity where the tail packet information is located, or the number of CG transmission opportunities where it is located, may be indicated, or it may be directly indicated by the characters in the UCI information. The implementation method can refer to the first implementation method and will not be repeated here.

Optionally, in some embodiments, the indication information may be downlink control information (DCI).

It should be understood that the DCI format may include, such as DCI format 0-0, DCI format 0-1, etc., and this application does not limit this.

Optionally, in some embodiments, sending indication information within the third CG cycle period also includes: within the third CG cycle period, after receiving the tail packet information indicated by UCI, sending second indication information, wherein the second indication information is used to indicate that UCI is not sent.

Specifically, taking Figure 4 as an example, illustratively, the terminal device can receive the tail packet information of the data packet at the fourth CG transmission opportunity. After the terminal device receives the tail packet information at the fourth CG transmission opportunity, when the UCI is sent at any CG transmission opportunity after the fourth CG transmission opportunity, the UCI is also used to indicate that the tail packet information has been received. After the network device receives the UCI, it sends a second indication information, and the second indication information is used to indicate that the UCI is not sent within the CG period.

Optionally, in some embodiments, when the indication information is used to indicate the transmission timing of the fifth CG carrying the fifth UCI, it may include multiple implementation methods, and this application does not limit the above indication methods.

For example, the indication information may indicate the position of the CG transmission opportunity, or indicate the number of CG transmission opportunities. The implementation method thereof may refer to the first implementation method, which will not be described in detail.

Optionally, the above indication information can be carried by using the original field and/or the newly added field. For example, when the indication information is configured by configuring the newly added field, all bits or part of the bits of the newly added field can be used to indicate the fifth CG transmission timing carrying the fifth UCI, and/or all values or part of the values of the newly added field can be used to indicate the fifth CG transmission timing carrying the fifth UCI.

Optionally, when the original field and/or the newly added field are used to indicate the position and/or number of the fifth CG transmission opportunity carrying the fifth UCI within the CG cycle period, the length of the original field and/or the newly added field is variable.

It should be understood that the configuration method of the newly added field increases the length of the existing indication information, and uses the newly added field to indicate the transmission timing of the fifth CG carrying the fifth UCI, and since the original field of the existing indication information is not reused or otherwise processed, the original field of the existing indication information will not cause any functional restrictions. Its implementation method can refer to the first implementation method and will not be repeated.
