CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority to the Chinese patent application filed with the State Intellectual Property Office of China on April 7, 2023, with application number 202310398367.2 and application name “A Configuration Authorization Transmission Method and Device”, the entire contents of which are incorporated by reference in this application.

Technical Field

The present application relates to the field of communication technology, and in particular to a method and device for transmitting a configured grant (CG).

Background Art

At present, for periodic services, CG can be used for resource configuration. CG means that during the uplink transmission process, uplink scheduling resources can be allocated once through radio resource control layer (RRC) signaling or downlink control information (DCI), and then the same resources can be reused periodically for uplink transmission.

Periodic services with large data volumes and dynamic changes, such as extended reality (XR) services, require more resources to support their transmission. However, in the solution that uses CG for resource allocation, only one CG transmission opportunity is configured in a CG cycle period, which cannot meet the transmission needs of periodic services with large data volumes and dynamic changes, such as XR.

Summary of the invention

The embodiments of the present application provide a CG transmission method and device for realizing the configuration of time domain resources for a CG transmission opportunity within a CG cycle period, which can better meet the transmission requirements of periodic services with large data volumes and dynamic changes.

In the first aspect, a configuration authorization transmission method is provided, which can be applied to a terminal or a chip, chip system, or processor applied to a terminal, and can also be applied to a logical node, logic module, or software that can realize all or part of the terminal functions. Taking the application of the method to a terminal as an example, the method includes: receiving configuration information and first indication information, the first indication information is used to indicate a first value; the first value has a corresponding relationship with multiple time domain resource parameter sets, and the corresponding relationship is configured by the configuration information, one of the multiple time domain resource parameter sets includes at least one time domain resource parameter, and the time domain resource parameters in a time domain resource parameter set are used to indicate the time domain resources of at least one configuration authorization CG transmission opportunity, and at least one CG transmission opportunity is within the CG cycle period; data is sent on at least one CG transmission opportunity.

Since the first value corresponds to multiple time domain resource parameter sets, after receiving the configuration information and the first indication information, the terminal can determine multiple CG transmission opportunities for sending data within a CG cycle period, which helps to improve the uplink transmission efficiency and better meet the transmission requirements of services with large data volumes and dynamic changes (such as XR services).

In one possible design, the method also includes: receiving second indication information, the second indication information being used to indicate time domain resources for determining at least one CG transmission opportunity based on a corresponding relationship.

In this way, the second indication information can be used to instruct the terminal to adopt the corresponding relationship to determine the time domain resources of the transmission opportunities within the CG cycle period, ensuring that the network equipment and the terminal adopt the same method to determine the time domain resources of the transmission opportunities within the CG cycle period, thereby ensuring that the network equipment and the terminal coordinately transmit data within the CG cycle period, thereby improving the reliability of the solution.

In one possible design, the first indication information is also used to indicate the time domain resources for determining at least one CG transmission opportunity based on the corresponding relationship.

In this way, the first indication information can be used to instruct the terminal to use the corresponding relationship to determine the time domain resources of the transmission opportunities within the CG cycle period, ensuring that the network equipment and the terminal use the same method to determine the time domain resources of the transmission opportunities within the CG cycle period, thereby ensuring that the network equipment and the terminal cooperate to transmit data within the CG cycle period without the need for additional signaling overhead.

In one possible design, the correspondence between the first value and the plurality of first time domain resource parameter sets is configured by a first information element in the configuration information. When the first information element exists in the configuration information, the time domain resource for at least one CG transmission opportunity is determined based on the correspondence.

In this way, when the corresponding relationship is configured, it is possible to use the corresponding relationship to determine the time domain resources of at least one CG transmission opportunity, thereby ensuring that the network device and the terminal transmit data in a coordinated manner within the CG cycle period.

In one possible design, a time domain resource parameter set includes at least one time domain resource parameter among a start symbol and length indicator value (SLIV), a scheduling delay parameter (such as K2), and a mapping type (mapping type) parameter.

In one possible design, the configuration information is used to configure multiple corresponding relationships, and the corresponding relationship between the first value and multiple time domain resource parameter sets is one of the multiple corresponding relationships.

In this way, configuration efficiency can be improved.

DETAILED DESCRIPTION

FIG. 1 is a schematic diagram showing a possible, non-limiting system. As shown in FIG. 1 , the communication system 10 includes a radio access network (RAN) 100 and a core network (CN) 200. Optionally, the communication system 10 also includes the Internet 300. 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. 1 , 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.

Among them, RAN 100 can be a cellular system related to the 3rd Generation Partnership Project (3GPP), such as a 4G, 5G mobile communication system, or a future-oriented evolution system (such as a 6G mobile communication system). RAN 100 can 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 can also be a communication system that integrates two or more of the above systems.

The RAN node 110, which may also sometimes be referred to as access network equipment, RAN entity or access node, etc., constitutes a part of the communication system to help terminals 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 Figure 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 Figure 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 one possible scenario, the RAN node may be a base station, an evolved evolved NodeB (eNodeB), access point (AP), transmission reception point (TRP), next generation NodeB (gNB), next generation base station in the sixth generation (6G) mobile communication system, base station in the future mobile communication system, or access node in the WiFi system, etc. The RAN node can be a macro base station (such as 110a in Figure 1), a micro base station or an indoor station (such as 110b in Figure 1), a relay node or a donor node, or a wireless controller in the CRAN scenario. Optionally, the RAN node can also be a server, a wearable device, a vehicle or an on-board device, etc. For example, the access network device in the vehicle to everything (V2X) technology can be a road side unit (RSU). All or part of the functions of the RAN node in this application can 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 this application can also be a logical node, a logical module or software that can implement all or part of the functions of the RAN node.

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).

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, CU, CU-CP, CU-UP, DU and RU are described as examples in this application. 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.

Terminal devices may also be referred to as terminals, user equipment (UE), mobile stations, mobile terminals, etc. Terminal devices can be widely used in various scenarios, such as device-to-device (D2D), vehicle-to-everything (V2X) communication, machine-type communication (MTC), Internet of Things (IOT), virtual reality, augmented reality, industrial control, autonomous driving, telemedicine, smart grid, smart furniture, smart office, smart wear, smart transportation, smart city, etc. Terminal devices may be mobile phones, tablet computers, computers with wireless transceiver functions, wearable devices, vehicles, drones, helicopters, airplanes, ships, robots, robotic arms, smart home devices, etc. The embodiments of the present application do not limit the specific technology and specific device form adopted by the terminal devices.

In the embodiment of the present application, the device for realizing the function of the terminal device may be the terminal device; or it may be a device capable of supporting the terminal device to realize the function, such as a chip system, which may be installed in the terminal device. In the technical solution provided in the embodiment of the present application, the technical solution provided in the embodiment of the present application is described by taking the device for realizing the function of the terminal device as the terminal device as an example.

The communication system shown in FIG1 above can support various radio access technologies (radio access technology, RAT). For example, the communication system shown in FIG1 can be a fourth generation (4G) communication system (also called a long term evolution (LTE) communication system), a 5G communication system (also called a new radio (NR) communication system), a 6G communication system, or a future-oriented evolution system.

In addition, the network architecture and business 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, and do not constitute a limitation on the technical solutions provided in the embodiments of the present application. Ordinary technicians in this field can know that with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of the present application are also applicable to similar technical problems.

In the embodiments of the present application, the RAN node can be expressed in different ways, such as base station, access network device, network device, etc., and in the present application, unless otherwise specified, network device is used to express it. Similarly, the terminal can be expressed in different ways, such as UE, mobile terminal, etc., and in the present application, unless otherwise specified, terminal is used to express it.

In this application, "(for example, a network device) sends information to...(for example, a terminal)" or the related illustrations in the accompanying drawings can be understood as the destination end of the information being the terminal. It can include sending information to the terminal directly or indirectly. For example, if the network device is a CU, when the CU sends information to the terminal, the CU first sends the information to the DU, and then the DU sends it to the terminal. In this application, "(for example, a network device) receives information from...(for example, a terminal)" or "(for example, a network device) receives...information from (for example, a terminal)", or the related illustrations in the accompanying drawings can be understood as the source end of the information being the terminal, which can include receiving information from the terminal directly or indirectly. For example, if the network device is a CU, when the CU receives information from the terminal, the DU receives the information from the terminal and sends the information to the CU, and the CU receives the information from the terminal through the DU. The information may be processed as necessary between the source and destination ends of the information transmission, such as format changes, but the destination end can understand the valid information from the source end. Similar expressions in this application can be understood similarly and will not be repeated here.

The terms "system" and "network" in the embodiments of the present application can be used interchangeably. "At least one" means one or more, and "plurality" means two or more. "And/or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and/or B can represent: A exists alone, A and B exist at the same time, and B exists alone, where A and B can be singular or plural. The character "/" generally indicates that the associated objects before and after are in an "or" relationship. "At least one of the following" or similar expressions refers to any combination of these items, including any combination of single items or plural items, such as at least one of a, b or c, which can represent: a, or b, or c, or a and b, or b and c, or a and c, or a and b and c.

With the continuous development of the fifth generation (5G) communication system, data transmission latency continues to decrease and transmission capacity is increasing. 5G communication systems are gradually infiltrating some multimedia services with strong real-time requirements and large data capacity requirements, such as video transmission, cloud gaming (CG) and extended reality (XR), among which XR includes virtual reality (VR) and augmented reality (AR).

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. With the continuous advancement and improvement of extended reality technology, related industries have also been booming. As a type of XR, VR technology has entered various fields closely related to people's production and life, such as education, entertainment, military, medical care, environmental protection, transportation, and public health. Compared with traditional video services, VR has the advantages of multiple perspectives and strong interactivity, providing users with a new visual experience.

In addition to smartphones, people increasingly hope to enhance their XR experience through terminals such as head mounted displays (HMD) or smart glasses (such as VR glasses and AR glasses). Therefore, as XR devices become more and more popular, how to improve transmission efficiency while ensuring user experience has become a key issue in current research.

For XR transmission services and video transmission services, their service models are usually based on frame rates and periodic arrival. As shown in Figure 2, for a video with a frame rate of 60 frames per second (FPS), ideally, one frame arrives every 16.67 milliseconds. Common frame rates for video frames are 30, 60, 90, and 120, and the corresponding frame periods are 33.33 milliseconds, 16.67 milliseconds, 11.11 milliseconds, and 8.33 milliseconds, respectively, and the frame periods are all non-integers.

For XR and video transmission services, the data volume is usually large. For example, the size of a 4K video frame is about 30 to 100KB. In addition, 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.

For different XR services, the business models for uplink and downlink are usually different. The changes in the scene content display of VR are caused by posture or position (action), so the content of uplink transmission is mainly position and posture information, with a small data volume, usually only tens of kbps. The content of downlink transmission is mainly the rendered video stream, with a relatively large data volume, up to tens to hundreds of Mbps.

Unlike VR, the changes in the scene content display of AR are caused by changes in the focus target and the changes in the spatial relationship between the position and the gaze point (action). AR uploads the visual information required for perception (including depth), so the main content of the uplink transmission is clear and stable pictures or video streams, or some extracted environmental feature information, so the data volume is large. According to industry research and evaluation, the network uplink rate required to meet the initial experience of interactive AR services is about 2Mbps, and 10 to 20Mbps is required to meet the advanced experience. Compared with VR, AR has a higher demand for uplink transmission rate, and uplink transmission is also more challenging.

Configured grant (CG) (or configured scheduling (CS)) is suitable for uplink transmission of periodic services. CG means that during the uplink transmission process, the uplink scheduling resources only need to be allocated once through the radio resource control layer (RRC) signaling or downlink control information (DCI), and then the same time-frequency resources can be reused periodically for uplink transmission. As shown in Figure 3, it is a schematic diagram of CG.

Normally, in the authorized frequency band, one uplink transmission opportunity is configured in each CG cycle period, that is, one transport block (TB) is transmitted in each CG cycle period. The CG cycle period refers to the time period in which the CG cycle is located. As shown in Figure 3, three CG cycle time periods are shown.

It can be understood that the transmission resource used for an uplink transmission can be called an uplink transmission opportunity (which can be referred to as a transmission opportunity for short). This article mainly relates to PUSCH transmission within the CG cycle period, and the uplink transmission opportunity can also be replaced by other possible descriptions, such as uplink transmission opportunity (which can be referred to as a transmission opportunity for short) or CG transmission opportunity or CG resource or PUSCH resource or PUSCH opportunity or PUSCH opportunity or PUSCH transmission resource, etc. Unless otherwise specified in this application, the CG transmission opportunity is used for expression.

For services with large data volumes and dynamic changes (such as XR services), configuring one CG transmission opportunity within a CG cycle period may not be able to complete data transmission. To address this problem, multiple CG transmission opportunities can be configured within a CG cycle period. As shown in Figure 4, it is a schematic diagram of configuring multiple CG transmission opportunities within a CG cycle period. It should be understood that Figure 4 takes the configuration of 3 CG transmission opportunities within a CG cycle period as an example, and is not limited to this.

CG includes Type 1 and Type 2. The main difference between the two types is the different ways of activating CG resources.

Type 1: Configure relevant parameters of CG transmission through RRC signaling, such as CG cycle period, CG resources (such as CG time domain resources, frequency domain resources, etc.), and activate corresponding CG resources through RRC signaling.

Exemplarily, a possible RRC signaling structure for configuring relevant parameters of CG transmission is:

In the above RRC signaling structure, the time domain allocation (timeDomainAllocation) field indicates a row in the time domain resource allocation (TDRA) table. The terminal can select the TDRA from the timeDomainAllocation field. This row of the table contains information such as mapping type, scheduling delay parameters (such as K2), and start and length indicator value (SLIV). There can be multiple TDRA tables. In type 1, the TDRA table used in CG configuration is determined according to the rules of DCI format 0_0.

For example, Table 1 shows the applicable PUSCH time domain resource allocation for common search space and DCI format 0_0 in UE specific search space, illustrating the rules for DCI format 0_0.

Table 1 Rules for DCI format 0_0

As can be seen from Table 1, the rules of DCI format 0_0 are: if both the pusch-Config field and the pusch-ConfigCommon field contain the PUSCH-time domain resource configuration table (PUSCH-TimeDomainResourceAllocationList) (i.e., TDRA table), the TDRA table defined in the pusch-Config field is used first; if only one of the pusch-Config field and the pusch-ConfigCommon field contains the PUSCH-time domain resource configuration table, the TDRA table defined in this field is used; if neither the pusch-ConfigCommon nor the pusch-Config field contains the PUSCH-time domain resource configuration table, the default TDRA table can be used.

In a specific implementation, the network device may configure PUSCH related information through RRC signaling, and the RRC signaling may carry a PUSCH configuration (pusch-Config) field and a PUSCH configuration common (pusch-ConfigCommon) field. It can be understood that the RRC signaling carrying the pusch-Config field, the RRC signaling carrying the pusch-ConfigCommon field, and the RRC signaling carrying the timeDomainAllocation field may be different RRC signaling.

For example, a possible pusch-ConfigCommon field is:

For example, a possible pusch-Config field is:

It can be seen that the two fields, pusch-ConfigCommon and pusch-Config, point to the PUSCH-TimeDomainResourceAllocationList field at the same time.

A possible structure of the PUSCH-TimeDomainResourceAllocationList field is:

It can be seen from the PUSCH-TimeDomainResourceAllocationList field that multiple rows can be configured in the TDRA table, up to 16 rows (i.e. maxNrofUL-Allocations-r16 indicates 16), each row contains a K2, a mapping type and a SLIV. The timeDomainAllocation field indicates one of the rows in the TDRA table, so that the terminal can obtain the K2, mapping type and SLIV information of the row, and then determine the time domain resources of an uplink transmission opportunity within the CG cycle period.

Type 2: Configure relevant parameters of CG transmission, such as CG cycle period, through RRC signaling, and configure and activate corresponding CG resources through DCI signaling.

Among them, the TDRA table is determined by the DCI type of the DCI signaling, and different DCI types correspond to different TDRA tables. For example, the DCI types include format 0_0 and format 0_1. If the DCI signaling is DCI format 0_0, the TDRA table is determined according to the rules of DCI format 0_0 (see Table 1 above, which will not be repeated here); if the DCI signaling is DCI format 0_1, the TDRA table is determined according to the rules of DCI format0_1.

For example, Table 2 shows the rules for DCI format 0_1, which shows the applicable PUSCH time domain resource allocation for DCI format 0_1 in UE specific search space scrambled with C-RNTI, MCS-C-RNTI, CS-RNTI or SP-CSI-RNTI:

Table 2 Rules for DCI format 0_1

As can be seen from Table 2, if the pusch-Config field contains multiple PUSCH-time domain resource configuration table (PUSCH-TimeDomainResource AllocationList-ForMultiPUSCH) or multiple PUSCH-time domain resource configuration table-r17 (PUSCH-TimeDomain ResourceAllocationList-ForMultiPUSCH-r17) (that is, TDRA multiple PUSCH-time domain resource configuration table-r17table), the above-mentioned TDRA table defined in the pusch-Config field is used first; if the pusch-Config field contains PUSCH-time domain resource configuration table-DCI-0-1, the TDRA table defined in the field of PUSCH-time domain resource configuration table-DCI-0-1 is used; if the pusch-Config field is not configured with multiple PUSCH-time domain resource configuration table, multiple PUSCH-time domain resource configuration table-r17, PUSCH-time domain resource configuration table-DCI-0-1, and the pusch-Config field, pusch-Config field, If the igCommon field contains the PUSCH-TimeDomainResourceAllocationList (i.e., TDRA table), the TDRA table defined in the pusch-Config field is used first; if the pusch-Config field is not configured with multiple PUSCH-time domain resource configuration tables, multiple PUSCH-time domain resource configuration tables-r17, or PUSCH-time domain resource configuration table-DCI-0-1, and only one of the pusch-Config field and the pusch-ConfigCommon field contains the PUSCH-time domain resource configuration table, the TDRA table defined in that field is used; if the pusch-Config field is not configured with multiple PUSCH-time domain resource configuration tables, multiple PUSCH-time domain resource configuration tables-r17, or PUSCH-time domain resource configuration table-DCI-0-1, and if neither the pusch-ConfigCommon nor the pusch-Config field contains the PUSCH-time domain resource configuration table, the default TDRA table can be used.

There is a bit field in the DCI signaling that can carry the TDRA index, which indicates a row in the TDRA table, so that the K2, mapping type, SLIV and other information of a row in the TDRA table can be determined.

From the above, it can be seen that since each row in the TDRA table only contains one K2, one mapping type and one SLIV, it only supports the time domain resources for configuring one CG transmission opportunity within one CG cycle period. As a result, it is impossible for network equipment to indicate that there are multiple CG transmission opportunities within one CG cycle period, and it is unable to meet the transmission requirements of periodic services with large data volumes and dynamic changes, such as XR.

In view of this, a technical solution of an embodiment of the present application is provided. When multiple CG transmission opportunities are supported to be configured within a CG cycle period within the authorized frequency band, the network device can indicate that there are multiple CG transmission opportunities within a CG cycle period, and realize the time domain resources of configuring one CG transmission opportunity within a CG cycle period, which can better meet the transmission requirements of periodic services with large data volumes and dynamic changes such as XR.

Refer to Figure 5, which is a flowchart of a CG transmission method provided in an embodiment of the present application. The method is applied to the scenario shown in Figure 1 as an example, and the method includes S501 to S502. It can be understood that the present application uses the network device and the terminal as an example to illustrate the execution subject of the interaction diagram, but the present application does not limit the execution subject of the interaction diagram. For example, the network device in the method provided by the present application can also be a chip, a chip system, or a processor applied to the network device, and can also be a logical node, a logical module or software that can implement all or part of the network device; the terminal in the method provided by the present application can also be a chip, a chip system, or a processor applied to the terminal, and can also be a logical node, a logical module or software that can implement all or part of the terminal functions.

S501: A network device sends configuration information and first indication information, and correspondingly, a terminal receives the configuration information and the first indication information.

Among them, the first indication information is used to indicate the first value; the first value has a corresponding relationship with multiple time domain resource parameter sets, and the corresponding relationship is configured by the configuration information. A time domain resource parameter set in the multiple time domain resource parameter sets includes at least one time domain resource parameter. The time domain resource parameters in a time domain resource parameter set are used to indicate at least one time domain resource for configuring an authorized CG transmission opportunity, and at least one CG transmission opportunity is within the CG cycle period.

In the embodiment of the present application, the configuration information can be used to configure a set of corresponding relationships, that is, the first value and the plurality of time domain resource parameter sets. configuration information can also be used to configure multiple sets of corresponding relationships, including the corresponding relationship between the first value and multiple time domain resource parameter sets.

For ease of description, in the following text, the time domain resource parameter set corresponding to the first value is defined as the first time domain resource parameter set, that is, the correspondence between the first value and multiple time domain resource parameter sets is specifically the correspondence between the first value and multiple first time domain resource parameter sets, and the correspondence between the first value and multiple time domain resource parameter sets is defined as the first correspondence.

Optionally, there is a second correspondence between the second value and at least one second time domain resource parameter set, and the configuration information can also be used to configure the second correspondence. For example, the configuration information includes the first correspondence and the second correspondence, or the configuration information includes configuration parameters of the first correspondence and configuration parameters of the second correspondence.

Among them, multiple first time domain resource parameter sets and at least one second time domain resource parameter set may be completely different, partially overlap, or completely the same, and this application does not impose any restrictions.

In a possible implementation, the configuration information may include a correspondence between at least one value and a time domain resource parameter set (hereinafter referred to as at least one correspondence). For example, the at least one correspondence includes the first correspondence described above; optionally, at least one correspondence also includes the second correspondence described above. After receiving the configuration information, the terminal may directly determine the at least one correspondence.

In another possible implementation, the configuration information may include at least one configuration parameter of a corresponding relationship, and after receiving the configuration information, the terminal determines at least one corresponding relationship according to the configuration parameter in the configuration information. For example, the configuration information includes indication information of at least one value, indication information of a time domain resource parameter set, etc.

The embodiments of the present application do not limit the specific form of the configuration information and the specific manner of the terminal configuration correspondence.

In an embodiment of the present application, when the configuration information can be used to configure multiple corresponding relationships, after the terminal receives the configuration information and the first indication information, the terminal can configure only one corresponding relationship, such as only configuring the first corresponding relationship. The terminal can also configure multiple corresponding relationships based on the configuration information, such as configuring the first corresponding relationship, the second corresponding relationship, etc., which is not limited in the embodiment of the present application.

In an embodiment of the present application, the types of resource parameters in the time domain resource parameters in a single time domain resource parameter set include, but are not limited to, one or more of SLIV, scheduling delay parameters (such as K2), and mapping types. Among them, the types of time domain resource parameters included in different time domain resource parameter sets may be the same or different. The number of time domain resource parameters included in different time domain resource parameter sets may be the same or different, and this application does not impose any restrictions.

SLIV: used to indicate the starting symbol (S) and number of symbols (L) occupied by the CG transmission opportunity in a time unit. For example, when the time unit is a time slot, SLIV represents the starting symbol index of the scheduled data and the number of symbols of the scheduled data in the scheduled time slot.

K2: used to indicate the time interval from PDCCH (i.e. DCI) to PUSCH (i.e. CG transmission opportunity), and the time unit of the time interval is, for example, a frame. For example, the network device sends DCI to the terminal device via PDCCH in time unit n, and the time unit corresponding to the CG data scheduled by the DCI and transmitted on PUSCH is n+K2.

Mapping type: used to indicate the PDSCH mapping type, for example, candidate values of the starting symbol (S), candidate values of the number of symbols (L), etc., where the candidate values of the starting symbol (S) and/or different numbers of symbols (L) corresponding to different mapping types may be different.

For example, Figure 6 is a schematic diagram of SLIV and K2 parameters. It can be understood that K2 in Figure 6 takes 2 time slots as an example, indicating that the CG transmission opportunity is in the third time slot after the DCI, but it is not limited to this.

In a possible design, the value in the corresponding relationship may specifically be an index value. For example, at least one corresponding relationship may specifically be in the form of a table, such as a TDRA table, and the value in at least one corresponding relationship is an index value of a row in the TDRA table, and each row record in the TDRA table includes one or more time domain resource parameter sets, wherein each row in at least one row has multiple time domain resource parameter sets. For example, the first row of the TDRA table contains the above-mentioned multiple second time domain resource parameter sets, and the second row of the TDRA table contains the above-mentioned at least one second time domain resource parameter set, then the above-mentioned first value is the index value of the first row, such as "1", and the second value is the index value of the second row, such as "2".

In order to distinguish the TDRA table provided in the embodiment of the present application, in which a row can correspond to multiple CG transmission opportunities, from the TDRA table described above, in which each row corresponds to only one CG transmission opportunity, in the following embodiments, the TDRA table provided in the embodiment of the present application, in which a row can correspond to multiple CG transmission opportunities, is referred to as the "first TDRA table", and the TDRA table described above, in which each row corresponds to only one CG transmission opportunity, is referred to as the "second TDRA table". It can be understood that there can be one or more second TDRA tables.

In an embodiment of the present application, the network device may send configuration information and first indication information at the same time, or may send configuration information first and then send the first indication information, which is not limited in the embodiment of the present application.

Further, the configuration information and/or the first indication information may be carried in physical layer signaling, such as DCI signaling, or may be carried in high-layer signaling, such as RRC signaling or a media access control layer control element (Media Access Control Control Element, MAC CE). This application is not limiting.

In addition, the configuration information and the first indication information may be carried in different signaling or in the same signaling, which is not limited in the embodiments of the present application.

For example, the configuration information may be a pusch-Config field and/or a pusch-ConfigCommon field, or a part of the pusch-Config field and/or the pusch-ConfigCommon field. The first indication information may be a timeDomainAllocation field.

In one example, when multiple CG transmission opportunities are configured within a CG cycle period in the authorized frequency band, an information element (IE) can be added to pusch-Config and/or pusch-ConfigCommon to indicate the first TDRA table. For example, the newly added IE is the PUSCH-TimeDomainResource Allocation-r18 field:

Among them, "SEQUENCE" is a loop function, SEQUENCE{k2-r16...} represents multiple rows of the first TDRA table; puschAllocationList-r16 SEQUENCE(SIZE(1..maxNrofMultiplePUSCHs-r16))OF PUSCH-Allocation-r16 represents multiple PUSCHs corresponding to a row; maxNrofMultiplePUSCHs represents the maximum number of PUSCHs corresponding to a row.

In a specific implementation, multiple rows are allowed to be configured in the PUSCH-TimeDomainResource Allocation-r18 field (i.e., the first TDRA table has multiple rows), and a maximum of N rows can be configured, and the nth row of the N rows contains n_m K2s, mapping types, and SLIVs. Among them, N can be 16, 64, or other values, which are not limited by the present invention. In addition, the n_m corresponding to different rows can be different, that is, the number of K2s, mapping types, and SLIVs contained in different rows of the first TDRA table can be different.

It can be understood that the original fields of pusch-Config and/or pusch-ConfigCommon (such as PUSCH-TimeDomainResource Allocation-r17, used to indicate the second TDRA table) remain unchanged. In other words, the pusch-Config field can contain both the first TDRA table and the second TDRA table, and the pusch-ConfigCommon field can contain both the first TDRA table and the second TDRA table.

As another example, when multiple CG transmission opportunities are configured within a CG cycle period in the authorized frequency band, the original PUSCH-TimeDomainResourceAllocationList field in pusch-Config and/or pusch-ConfigCommon can be directly reused, for example, by replacing the value in the PUSCH-TimeDomainResource Allocation-r17 field to indicate the first TDRA table.

S502. The terminal sends data at at least one CG transmission opportunity, and correspondingly, the network device receives data at at least one CG transmission opportunity.

Specifically, after receiving the configuration information, the terminal can determine the correspondence between the first value and multiple time domain resource parameter sets, and determine the first value according to the first value indication information; determine the multiple time domain resource parameter sets corresponding to the first value according to the first value and the correspondence between the first value and multiple time domain resource parameter sets; determine the time domain resources of at least one CG transmission opportunity within the CG cycle period according to the time domain resource parameters of each time domain resource parameter set in the multiple time domain resource parameter sets.

Because there are multiple time domain resource parameter sets corresponding to the first value, the terminal can determine the time domain resources of at least one CG transmission opportunity within the CG cycle period according to each time domain resource parameter set. Therefore, the terminal can determine the time domain resources of multiple CG transmission opportunities within the CG cycle period according to multiple time domain resource parameter sets.

For example, the first value corresponds to three time domain resource parameter sets, and the time domain resource parameters in each time domain resource parameter set are used to indicate a If the time domain resources for the authorized CG transmission opportunities are configured, the terminal can determine the time domain resources for the three CG transmission opportunities within the CG cycle period based on the three time domain resource parameter sets.

For example, the first value corresponds to two time domain resource parameter sets, where the time domain resource parameters in one time domain resource parameter set are used to indicate a time domain resource for a configured authorized CG transmission opportunity, and the time domain resource parameters in the other time domain resource parameter set are used to indicate two time domain resources for configured authorized CG transmission opportunities. The terminal can determine the time domain resources for three CG transmission opportunities within the CG cycle period based on the two time domain resource parameter sets.

For example, the first value corresponds to two time domain resource parameter sets, where the time domain resource parameters in one time domain resource parameter set are used to indicate a time domain resource for configuring an authorized CG transmission opportunity, and the time domain resource parameters in the other time domain resource parameter set are used to indicate another time domain resource for configuring an authorized CG transmission opportunity. The terminal can determine the time domain resources of three CG transmission opportunities within the CG cycle period based on the two time domain resource parameter sets.

It should be understood that the above three examples are merely illustrative and are not limited thereto.

After the terminal determines the time domain resources of multiple CG transmission opportunities within the CG cycle period based on multiple time domain resource parameter sets corresponding to the first value, within each CG cycle period, the terminal sends data on at least one of the multiple CG transmission opportunities, and the network device receives data on the transmission opportunity.

It can be understood that although the network device indicates that there are time domain resources with multiple CG transmission opportunities within a CG cycle period, the terminal can send data on all of the multiple CG transmission opportunities or on some of the multiple CG transmission opportunities during transmission. Therefore, in each CG cycle period, the terminal sends data on at least one transmission opportunity, and the network device receives data on at least one transmission opportunity.

Through the above S501~502, when multiple CG transmission opportunities are configured within a CG cycle period in the authorized frequency band, the network device can indicate that there are multiple CG transmission opportunities within a CG cycle period, so that the terminal can have multiple CG transmission opportunities for data transmission within a CG cycle period, which helps to improve the uplink transmission efficiency and better meet the transmission requirements of services with large data volumes and dynamic changes.

It can be understood that in a specific implementation, in addition to configuring the corresponding relationships provided in S501 to S502 above, the terminal may also configure other corresponding relationships for determining the time domain resources of the CG transmission opportunities within the CG cycle period. For example, the terminal is configured with a first TDRA table (one row can correspond to multiple PUSCHs) and at least one second TDRA table (each row corresponds to only one PUSCH). Therefore, the terminal needs to determine based on which corresponding relationship to determine the time domain resources of at least one CG transmission opportunity.

Here are several possible implementations:

Method 1: The network device indicates the corresponding relationship used by the terminal through signaling.

Exemplarily, the network device may send second indication information to the terminal (the second indication information is different from the first indication information), and the second indication information is used to indicate the determination of the time domain resources of at least one CG transmission opportunity based on a corresponding relationship (the corresponding relationship here may simply refer to the corresponding relationship between the first value and multiple first time domain resource parameter sets, or may refer to the corresponding relationship between the value and the time domain resource parameter set (such as the first TDRA table exemplified above)), or in other words, the second indication information is used to indicate that the determination of the time domain resources of at least one CG transmission opportunity is based on the corresponding relationship; the terminal receives the second indication information, determines the time domain resources of at least one CG transmission opportunity based on the corresponding relationship according to the second indication information, and then sends data at the determined CG transmission opportunity.

Optionally, the second indication information may be carried in RRC signaling or DCI signaling or MAC CE. The second indication information and the configuration information may be carried in the same signaling or in different signaling, and this application does not impose any restrictions. In a possible example, the network device first sends configuration information to the terminal, then sends the second indication information to the terminal, and finally sends the first indication information to the terminal, and then the terminal can sequentially obtain the corresponding relationship based on the configuration information (such as the first TDRA table), determine the time domain resources of at least one CG transmission opportunity based on the corresponding relationship (such as the first TDRA table) based on the second indication information, and determine the first corresponding relationship based on the first indication information (such as a row in the first TDRA table).

In one implementation, as long as the terminal receives the second indication information, it determines the time domain resources of at least one CG transmission opportunity based on the corresponding relationship (such as the first TDRA table). For example, the first indication information is the first field in the RRC signaling, DCI signaling, or MAC CE. As long as the RRC signaling, DCI signaling, or MAC CE carries the first field, the terminal determines the time domain resources of at least one CG transmission opportunity based on the corresponding relationship (such as the first TDRA table).

Optionally, when the terminal does not receive the second indication information, the terminal can determine the time domain resources of at least one CG transmission opportunity based on the second TDRA table.

In another implementation, when the value of the second indication information is a preset value, the terminal determines the time domain resource of at least one CG transmission opportunity based on the corresponding relationship (such as the first TDRA table exemplified above). For example, RRC signaling or DCI signaling or MAC CE carries The second field, when the value of the second field is 0, the terminal determines the time domain resources for at least one CG transmission opportunity based on the corresponding relationship; when the value of the second field is 1, the terminal does not determine the time domain resources for at least one CG transmission opportunity based on the corresponding relationship; or when the value of the second field is 1, the terminal determines the time domain resources for at least one CG transmission opportunity based on the corresponding relationship; when the value of the second field is 0, the terminal does not determine the time domain resources for at least one CG transmission opportunity based on the corresponding relationship.

Optionally, when the value of the second indication information is not a preset value, the terminal can determine the time domain resources of at least one CG transmission opportunity based on the second TDRA table.

In this way, the network device can instruct the terminal to use the corresponding relationship described in S501~S502 to determine the time domain resources of the transmission opportunities within the CG cycle period, ensuring that the network device and the terminal use the same method to determine the time domain resources of the transmission opportunities within the CG cycle period, and then ensuring that the network device and the terminal cooperate to transmit data within the CG cycle period, thereby improving the reliability of the solution.

Method 2, the corresponding relationship (the corresponding relationship here may refer to the corresponding relationship between the value and the time domain resource parameter set (such as the first TDRA table), or may simply refer to the corresponding relationship between the first value and multiple first time domain resource parameter sets (such as a row in the first TDRA table)) is configured by the first information element in the configuration information. When the first information element exists in the configuration information, the terminal determines the time domain resources for at least one CG transmission opportunity based on the corresponding relationship. In other words, as long as the terminal configures the corresponding relationship, the terminal determines the time domain resources for at least one CG transmission opportunity based on the corresponding relationship.

Continuing with the example of type 1 in S501 above, if there is a newly added PUSCH-TimeDomainResource Allocation-r18 field in the pusch-Config and/or pusch-ConfigCommon fields, the terminal determines to use the TDRA table (i.e., the first TDRA table) defined by the PUSCH-TimeDomainResource Allocation-r18 word to determine the time domain resources for at least one CG transmission opportunity.

Taking CG type 1 as an example, the network device configures the relevant parameters of CG transmission through RRC signaling and activates CG resources through RRC signaling. Table 3 provides a rule for DCI format 0_0 for an embodiment of the present application:

Table 3 Rules for DCI format 0_0

It can be seen from Table 3 that if the pusch-Config field contains pusch-TimeDomainAllocationList-R18 (equivalent to the first TDRA table in this article), the first TDRA table is used first.

It can be understood that Table 3 includes the first TDRA Table in the present application in the pusch-Config field, but is not limited to this. The first TDRA Table in the present application can also be included in the pusch-ConfigCommon field.

In this way, when the corresponding relationship described in S501 to S502 (i.e., the first TDRA table) is configured, the corresponding relationship is used preferentially to determine the time domain resources of at least one CG transmission opportunity; when the corresponding relationship is not configured, other corresponding relationships (such as the second TDRA table) are used to determine the time domain resources of at least one CG transmission opportunity, thereby ensuring that the network device and the terminal transmit data collaboratively within the CG cycle period.

Method 3: The first indication information is also used to indicate that the time domain resources of at least one CG transmission opportunity are determined based on the corresponding relationship, or in other words, the first indication information is also used to indicate that the time domain resources of at least one CG transmission opportunity are determined based on the corresponding relationship.

Taking type 2 as an example, the network device configures the relevant parameters of CG transmission through RRC signaling, and configures and activates CG resources through DCI signaling. For example, the first indication information is a DCI instruction or is carried in a DCI instruction. The time domain resources for at least one CG transmission opportunity can be determined based on the corresponding relationship according to the DCI type.

The TDRA table is determined by the DCI signaling, which can be specifically determined according to the DCI type of the DCI signaling. Different DCI types correspond to different TDRA tables. For example, the DCI types include format 0_0 and format 0_1. When multiple CG transmission opportunities are configured within a CG cycle period in the authorized frequency band, if the DCI signaling is DCI format 0_0, the TDRA table is determined in accordance with the rules of DCI format 0_0 provided in the embodiment of the present application (refer to the rules of DCI format 0_0 shown in Table 3); if the DCI signaling is DCI format 0_1, the TDRA table is determined in accordance with the rules of DCI format 0_1 provided in the embodiment of the present application.

The rules for format 0_0 when supporting multiple CG transmission opportunities within a CG cycle period in the authorized frequency band are shown in Table 3 and are not repeated here.

The rules of format 0_1 when multiple CG transmission opportunities are configured within a CG cycle period in the licensed frequency band are as follows:

Table 4

If the pusch-Config field contains a multi-PUSCH-time domain resource configuration table (PUSCH-TimeDomainResource AllocationList-ForMultiPUSCH) or a multi-PUSCH-time domain resource configuration table-r17 (PUSCH-TimeDomain ResourceAllocationList-ForMultiPUSCH-r17) or a multi-PUSCH-time domain resource configuration table-r18 (PUSCH-TimeDomainResourceAllocationList-ForMultiPUSCH-r18, equivalent to the first TDRA table in this article), the above-mentioned TDRA table defined in the pusch-Config field is used first; if the pusch-Config field contains PUSCH-time domain resource configuration table-DCI-0-1, the TDRA defined in the PUSCH-time domain resource configuration table-DCI-0-1 in this field is used. table; if the pusch-Config field is not configured with multiple PUSCH-time domain resource configuration tables, multiple PUSCH-time domain resource configuration tables-r17, multiple PUSCH-time domain resource configuration tables-r18, PUSCH-time domain resource configuration table-DCI-0-1, and the pusch-Config field and the pusch-ConfigCommon field both contain the PUSCH-time domain resource configuration table (PUSCH-TimeDomainResourceAllocationList) (i.e., TDRA table), the TDRA table defined in the pusch-Config field is used first; if the pusch-Config field is not configured with multiple PUSCH-time domain resource configuration tables, multiple PUSCH-time domain resource configuration tables-r17, multiple PUSCH-time domain resource configuration tables-r18, PUSCH-time domain resource configuration table-DCI-0-1, and the pusch-Config word If only one of the segments and pusch-ConfigCommon fields contains the PUSCH-time domain resource configuration table, the TDRA table defined in this field is used; if the pusch-Config field is not configured with multiple PUSCH-time domain resource configuration tables, multiple PUSCH-time domain resource configuration tables-r17, or PUSCH-time domain resource configuration table-DCI-0-1, and if neither the pusch-ConfigCommon nor the pusch-Config fields contain the PUSCH-time domain resource configuration table, the default TDRA table can be used.

It can be understood that the rules of format 0_0 when multiple CG transmission opportunities are supported in one CG cycle period in the authorized frequency band (such as Table 3) and the rules of format 0_0 when multiple CG transmission opportunities are not supported in one CG cycle period in the authorized frequency band (such as Table 1) may be different; the rules of format 0_1 when multiple CG transmission opportunities are supported in one CG cycle period in the authorized frequency band (such as Table 4) and the rules of format 0_1 when multiple CG transmission opportunities are not supported in one CG cycle period in the authorized frequency band (such as Table 2) may be different. Different TDRA tables can be determined based on different rules of format 0_0 or rules of format 0_1. For example, when multiple CG transmission opportunities are supported in one CG cycle period in the authorized frequency band, the TDRA table to be used can be determined based on the rules of format 0_0 provided in Table 3; when multiple CG transmission opportunities are not supported in one CG cycle period in the authorized frequency band, the TDRA table to be used can be determined based on the rules of format 0_0 provided in Table 1.

In this way, when the corresponding relationship described in S501 to S502 (i.e., the first TDRA table) is configured, the corresponding relationship can be used to determine the time domain resources of at least one CG transmission opportunity; when the corresponding relationship is not configured, other corresponding relationships (such as the second TDRA table) can be used to determine the time domain resources of at least one CG transmission opportunity, thereby ensuring that the network equipment and the terminal coordinately transmit data within the CG cycle period without adding additional signaling overhead.

It can be understood that the above implementation modes can be implemented separately or in combination with each other, and this application does not limit them.
