Description

Technical Field

[0001] This application relates to the field of wireless communication technology, and in particular to a method and apparatus for configuring data resources. Background Technology

[0002] Using existing technology, after obtaining the CG PUSCH configuration information, the data transmitting device sends data according to the resources configured in the CG PUSCH based on its own cached data to be sent. The data receiver then blindly checks the CG PUSCH resources configured for the data transmitting device to obtain the information sent by the data transmitter.

[0003] When there are multiple data transmission methods that the data transmitting device actually uses CG PUSCH resources for, the complexity of blind detection of data transmission by the data receiving device can be very high. This is especially true for XR service transmission. If multiple data transmission opportunities can be configured within a single period P of the CG PUSCH, and the actual data transmission start time, whether the data transmission is repeated, and the number of transmission opportunities occupied by the data transmission are all uncertain, complex blind detection may affect the normal operation of the data receiving end. For example, if there are X1 transmission opportunities within a CG PUSCH period, the actual data transmission within that period may occupy resources on X2 (X2≤X1) of these transmission opportunities. Furthermore, the actual data on X3 (X3≤X2) of these transmission opportunities may be the same, representing repeated data transmission. Alternatively, the actual data on X4 (X4≤X2) of these transmission opportunities may form a transmission block with the actual data on one or more other transmission opportunities. The actual data transmission situation may differ in different CG PUSCH periods; X2, X3, and X4 may all be different. Thus, the data receiving end experiences high complexity and low efficiency in blind detection of data. Summary of the Invention

[0004] This application proposes a data resource configuration method and device to solve the problems of high complexity and low efficiency in the actual data transmission on the blind detection CG PUSCH resource of the data receiver, and to meet the resource efficiency requirements and device complexity requirements of data transmission.

[0040] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0041] The application scenario of this application is for data information between network-side devices (e.g., gNB) and terminal-side devices (e.g., UE).

[0042] Taking the data transmitting device as the UE and the data receiving device as the gNB as an example, in this application's data scheme, the UE and gNB pre-determine a combination of data transmission methods that actually occupy CG PUSCH resources. This combination includes at least one transmission method, where each method is any one of the following: the actual data transmission start time, the number of transmission times occupied by the actual data transmission, the number of repetitions of the actual data transmission, the combined number of transmission times corresponding to the actual data transmission, and the correspondence between the type of actual data transmission and the transmission time. The gNB indicates the data transmission method combination in the CG PUSCH configuration information, or the UE sends indication information carrying the data transmission method combination. Based on the data detection results and the data transmission method combination, the gNB determines the reusable resources in the CG PUSCH resources and allocates them to other UEs.

[0043] The technical solutions provided by the various embodiments of this application are described in detail below with reference to the accompanying drawings.

[0044] Figure 1 This is a flowchart illustrating an embodiment of the method of this application.

[0045] This application proposes a method for configuring data resources, comprising the following steps 110-130:

[0046] Step 110: Determine the first resource, which is an uplink data transmission resource configured according to a set period, and contains N available data transmission opportunities in any period.

[0047] For example, the period of the first resource is P, and the Qth period of the first resource contains N≥2 transmission opportunities.

[0048] The first resource is the CG PUSCH resource. CG PUSCH scheduling periodically allocates PUSCH resources to a specific UE. There are two types of CG PUSCH configuration resources: one is CG PUSCH type 1, where all transmission grant resources are provided by the RRC, and the UE stores this configuration and uses it as the grant configuration when there is uplink data transmission. The other is CG PUSCH type 2, where the RRC layer configures the CG PUSCH period, HARQ sequence number, and other information, and then the Physical Downlink Control Channel (PDCCH) indicates whether the configuration is activated or deactivated.

[0049] The first resource satisfies periodicity. Taking the period P as an example, to meet the transmission requirements of the jitter of the arrival time of service data and / or the fluctuation of the size of service data volume, within one period of the first resource, there are N≥2 transmission opportunities. Since in the case where any item such as the actual data transmission start transmission opportunity in one period P of CGPUSCH is uncertain, whether the data transmission is repeated transmission data is uncertain, and the number of transmission opportunities occupied by data transmission is uncertain, the gNB needs to detect all possibilities of data transmission on the CG PUSCH resource, and the complexity of detection is very high, which affects the complexity of the gNB and the detection efficiency.

[0050] Step 120: Determine the target transmission mode, where the target transmission mode is one of the set transmission modes, and each set transmission mode includes a distribution of actual data transmission opportunities within any period.

[0051] For example, the gNB and / or the UE determine a combination of data transmission modes, where the combination of data transmission modes includes at least one transmission mode, and the transmission mode includes the start transmission opportunity of actual data transmission on the first resource, the number of transmission opportunities occupied by actual data transmission, the number of repetitions of actual data transmission, the combined number of transmission opportunities corresponding to actual data transmission, and the distribution of actual data transmission opportunities described by any item parameter in the actual data transmission format.

[0052] In this embodiment, by restricting the usage mode of resources on each transmission opportunity when transmitting actual data on the CG PUSCH resource, the complexity of the gNB detecting data on the CG PUSCH and the usage efficiency of the CG PUSCH resource can be controlled. Specifically, as Figures 10-14 shown are examples of data transmission modes A1 - A4, B1 - B4, C1 - C4, D1 - D4, E1 - E4 (for detailed description, see below).

[0053] Step 130: Determine M transmission opportunities among the N transmission opportunities within any period as the second resource for transmitting target data, where the M transmission opportunities satisfy the target transmission mode.

[0054] After determining one of the combinations of data transmission modes as the target transmission mode, determine the second resource according to the target transmission mode. The second resource is M transmission opportunities of the first resource within the Qth period time, M < N; the second resource is used to transmit target data.

[0055] Determine one of the combinations of data transmission modes as the target transmission mode, and determine the second resource according to the target transmission mode. The second resource is M transmission opportunities of the first resource within the Qth period time, M < N. This second resource is used to transmit target data.

[0056] For example, on the UE side, the second resource is determined according to the target transmission mode, and the target data is sent on the second resource. The resources on N≥2 transmission opportunities within the Qth cycle time of the CG PUSCH are configured to meet the arrival time jitter of service data and the floating change of the packet size of service data. Actually, the data sent by occupying the CG PUSCH resource within the Qth cycle time occupies M transmission opportunities, where M < N. In the case where the gNB predicts in advance the way in which the UE actually occupies the transmission opportunity for data transmission on the CG PUSCH resource, the gNB does not need to always detect these N transmission opportunities, which can improve the detection efficiency of the gNB.

[0057] Preferably, the UE determines the above data transmission mode combination and / or the target transmission mode, and sends the relevant information to the gNB to achieve the purpose of presetting this information by both parties. For some services, the UE can predict future data parameters better than the gNB. As the determiner of the data transmission mode combination and / or the target transmission mode, the UE can obtain more efficient data resource utilization efficiency and gNB data detection efficiency.

[0058] For another example, on the gNB side, the target transmission mode is selected according to the determined second resource, and a notification is sent to the terminal device. Therefore, it is also possible for the gNB to determine the above data transmission mode combination and / or the target transmission mode, and send the relevant indication information to the UE.

[0059] Preferably, after the gNB obtains the information of the UE's data transmission mode combination and / or obtains the information carrying the target transmission mode, the third resource on the CG PUSCH can be allocated to other UEs. Taking the UE currently configured with the CG PUSCH resource as the first terminal device as an example, if the first device determines to send data using the second resource in the first resource according to the information of the data transmission mode combination and / or the information of the target transmission mode, the gNB can allocate the third resource to the second terminal device. The third resource belongs to the first resource and does not belong to the second resource. Thus, the utilization efficiency of the CG PUSCH resource is improved, and the network capacity can be further enhanced.

[0060] It should be noted that the above steps are applicable to network entities in a wireless communication system, including terminal devices, network devices or other intermediate devices. The above steps can also be used for a service device that provides information processing for the network entity device. The above steps can also be used for any device, system, subsystem, circuit, chip or software entity that provides information reception, transmission, identification, and processing for terminal devices or network devices.

[0061] Figure 2This is a schematic diagram of CG PUSCH type 2. In step 110, for example, the first resource is a CG PUSCH resource. CGPUSCH scheduling periodically allocates PUSCH resources to a specific UE. There are two types of CG PUSCH configuration resources: one is CG PUSCH type 1, where all transmission-granted resources are provided by RRC. The UE stores this configuration and uses it as a grant configuration when there is uplink data transmission. The configuration information for CG PUSCH type 1 includes the time, frequency, and resource location of the PUSCH. The other is CG PUSCH type 2, where the RRC layer configures the CG PUSCH period, HARQ sequence number, and other information, and then the Physical Downlink Control Channel (PDCCH) indicates whether the configuration is activated or deactivated. The PDCCH that activates or deactivates the CG PUSCH contains the resources occupied by the PUSCH in terms of time and frequency, as well as the time location of the first CG PUSCH. After obtaining the activation information, the UE can determine all CG PUSCH resources based on the time, frequency, and location of the first CG PUSCH and the period configured for that CG PUSCH. Figure 2 It is CG PUSCH type 2. After the UE obtains the PDCCH that activates the CG PUSCH, it periodically occupies the CG PUSCH resources to send uplink information.

[0062] Regardless of whether it is CG PUSCH type 1 or CG PUSCH type 2, the configuration information includes parameters required for uplink transmission such as periodicity, number of HARQ processes (nrofHARQ-Processes), power control, number of repetitions (repK), and redundant version of the repetition (repK-RV).

[0063] Figure 3 This is a diagram illustrating repeated transmission of the CG PUSCH type.

[0064] CG PUSCH transmission supports repeated transmissions to improve reliability, and the number of repeated transmissions is configured via the parameter repK. When repK > 1, the UE should repeatedly transmit the same TB K times on K transmission opportunities, where the K transmission opportunities are located in K consecutive time slots within a period. Figure 3 The diagram shown is for repK=4.

[0065] Figure 4 This is a diagram illustrating the configuration of multiple data transmission opportunities within a single CG PUSCH cycle. For example, the CG PUSCH configuration related to XR services. While packet arrival for Extended Reality (XR) services is periodic, the actual arrival time of packets may experience jitter, causing them to arrive randomly within the jitter time window. Figure 4In the example, the first jitter time window begins at time t0, during which XR data packets can arrive within this time window between t0 and t3. In the diagram, the XR data packet arrives at time t1. The next XR data packet arrives after time P, and its arrival time can be any time within the jitter time window between t4 and t7. In the diagram, the next XR data packet arrives at time t7. To accommodate the jitter characteristics of XR service arrival time, multiple data transmission opportunities, i.e., the first resource, can be configured within one period P of the CG PUSCH to ensure timely transmission of service packets upon arrival.

[0066] Figure 5 This diagram illustrates the actual data transmission during multiple data transmission opportunities within one CG PUSCH cycle. The XR packet size varies over time. Taking AR / VR at 30Mbps as an example, the maximum packet size is 93,750 bytes, and the minimum packet size is 31,250 bytes. Based on the implementation of multiple PUSCH transmission opportunities within one CG PUSCH cycle, the amount of PUSCH resources occupied by a data packet is determined by the size of the data packet. As shown in the diagram, in the first CG PUSCH cycle, XR data packets occupy the resources of 3 PUSCHs. In the next CG PUSCH cycle, XR data packets occupy the resources of 1 PUSCH.

[0067] Figure 6 This is a flowchart illustrating an embodiment of the method of this application used in a network-side device.

[0068] The method described in any embodiment of the first aspect of this application, used in a network-side device, includes the following steps 211 to 214. In this embodiment, the network-side device determines a second resource of the target device and sends a target transmission method for satisfying the transmission of the second resource as third indication information to the terminal device.

[0069] Step 211: Send first indication information. The first indication information is used to determine the first resource. The first resource is an uplink data transmission resource configured according to a set period. Any period contains N available data transmission opportunities.

[0070] Step 212: Send second instruction information. The second instruction information is used to determine multiple set transmission modes. Each set transmission mode includes the distribution of actual data transmission opportunities within any period.

[0071] Step 213: Determine M transmission opportunities out of N transmission opportunities within any period as the second resource for transmitting target data. The M transmission opportunities satisfy the target transmission mode, which is one of the set transmission modes.

[0072] The network-side device determines the second resource based on the target data to be transmitted, and further selects the target transmission method from the various preset transmission methods.

[0073] After determining the second resource through steps 211 to 213, the network-side device receives the uplink target data through the second resource.

[0074] Optionally, embodiments of this application, used for network-side devices, further include the following steps:

[0075] Step 214: Send downlink third indication information, which is used to indicate the target transmission mode.

[0076] The terminal device that receives the third instruction information can determine the target transmission mode based on the third instruction information, and then determine the second resource, and send the uplink target data through the second resource.

[0077] Figure 7 This is a flowchart of another embodiment of the method of this application used in a network-side device.

[0078] The method described in any embodiment of the first aspect of this application, used in a network-side device, includes the following steps 221 to 223. In this embodiment, the network-side device determines a target transmission mode based on received second indication information and / or third indication information, and determines the second resource based on the target transmission mode.

[0079] Step 221: Send first indication information. The first indication information is used to determine the first resource. The first resource is an uplink data transmission resource configured according to a set period. Any period contains N available data transmission opportunities.

[0080] Step 222: Receive second indication information, which is used to determine multiple preset transmission modes, each preset transmission mode including a distribution of actual data transmission opportunities within any period. And / or, receive third indication information, which is used to indicate a target transmission mode, the target transmission mode being one of the preset transmission modes.

[0081] The network-side device determines the various preset transmission methods based on the second instruction information, or the network-side device contains pre-stored information on the various preset transmission methods.

[0082] Furthermore, the network-side device selects one of a variety of preset transmission methods as the target combination method, or determines the target transmission method among the variety of preset transmission methods based on the received third instruction information.

[0083] Step 223: Determine M transmission opportunities out of N transmission opportunities within any given period as the second resource for transmitting the target data. The M transmission opportunities satisfy the target transmission mode, which is one of the set transmission modes.

[0084] The network device determines M transmission opportunities for the second resource from N transmission opportunities for the first resource based on the target transmission method.

[0085] Further, after obtaining information about the data transmission mode combination from the first terminal device, and or after obtaining information carrying the target transmission mode, the third resource is allocated to the second terminal device, wherein the third resource belongs to the first resource and does not belong to the second resource.

[0086] Figure 8 This is a flowchart illustrating an embodiment of the method of this application used in a terminal-side device.

[0087] The method described in any embodiment of the first aspect of this application, used in a terminal-side device, includes the following steps 311 to 314. In this embodiment, the terminal device selects a target transmission mode from a variety of preset transmission modes based on a second resource for transmitting data, in order to satisfy the second resource.

[0088] Step 311: Receive first indication information. The first indication information is used to determine the first resource. The first resource is an uplink data transmission resource configured according to a set period, and any period contains N available data transmission opportunities.

[0089] Step 312: Receive second indication information, which is used to determine multiple preset transmission modes. Each preset transmission mode includes a distribution of actual data transmission opportunities within any period. Alternatively, the terminal device contains pre-stored information on multiple preset transmission modes.

[0090] Step 313: Determine M transmission opportunities out of N transmission opportunities within any period as the second resource for transmitting target data. The M transmission opportunities satisfy the target transmission mode, which is one of the set transmission modes.

[0091] The terminal device determines the second resource based on the target data to be transmitted, and further selects the target transmission method from the various set transmission methods.

[0092] After determining the second resource through steps 311 to 313, the terminal device sends the uplink target data through the second resource.

[0093] Optionally, embodiments of this application, used in terminal-side devices, may further include the following steps:

[0094] Step 314: Send the uplink third indication information, which is used to indicate the target transmission mode.

[0095] The network-side device that receives the third indication information can determine the target transmission mode based on the third indication information, and then determine the second resource, and receive the uplink target data through the second resource.

[0096] Figure 9 This is a flowchart of another embodiment of the method of this application used in a terminal-side device.

[0097] The method described in any embodiment of the first aspect of this application, used in a terminal-side device, includes the following steps 321 to 323. In this embodiment, a target transmission mode is determined based on received indication information, and target data is transmitted according to a second resource satisfying the target transmission mode.

[0098] Step 321: Receive first indication information. The first indication information is used to determine the first resource. The first resource is an uplink data transmission resource configured according to a set period, and any period contains N available data transmission opportunities.

[0099] Step 322: Receive second indication information, which is used to determine multiple preset transmission modes, each preset transmission mode including a distribution of actual data transmission opportunities within any period. And / or, receive third indication information, which is used to indicate a target transmission mode, the target transmission mode being one of the preset transmission modes.

[0100] The terminal device determines multiple preset transmission modes based on the second instruction information, or the terminal device contains pre-stored information on multiple preset transmission modes. The terminal device selects a target transmission mode from among the multiple preset transmission modes, or the terminal device determines the target transmission mode based on the third instruction information.

[0101] Step 323: Determine M transmission opportunities out of N transmission opportunities within any period as the second resource for transmitting target data. The M transmission opportunities satisfy the target transmission mode, which is one of the set transmission modes.

[0102] Specifically, the terminal device determines M transmission opportunities for the second resource (or the third resource) from the N transmission opportunities of the first resource according to the target transmission method.

[0103] In any embodiment of this application, preferably, the actual data transmission timing distribution includes at least one of the following parameters: the starting transmission timing of actual data transmission, the number of transmission timings occupied by actual data transmission, the number of repetitions of actual data transmission, and the combined number of transmission timings corresponding to actual data transmission.

[0104] In any embodiment of this application, preferably, the set transmission method further includes the data transmission format distribution of the actual data transmission timing.

[0105] For example, the transmission method includes the actual data start transmission timing and the number of transmission timings occupied by the actual data transmission at each start transmission timing.

[0106] For example, the transmission method includes the actual data start transmission timing and the number of times the actual data is repeated at each start transmission timing.

[0107] For example, the transmission method includes the actual data start transmission timing and the combined number of each start transmission timing.

[0108] For example, the transmission method includes the actual data initiation timing and the actual data transmission format.

[0109] The following examples illustrate different data transmission methods:

[0110] Figure 10 This diagram illustrates the distribution of actual data transmission start times on CG PUSCH configuration resources. The data transmission method that actually occupies CG PUSCH resources is either the transmission start time of the actual data transmission, or the transmission start time of the actual data transmission and the number of transmission times occupied.

[0111] The data transmission method that actually occupies CG PUSCH resources refers to the transmission timing at which the actual data transmission begins. The UE and gNB preset the transmission timing at which the actual data transmission begins. For example... Figure 10 As shown, data transmission modes A1, A2, A3, and A4 refer to the cases where the actual data transmission start time within the transmission period of CG PUSCH, and the transmission time j satisfies mod(j,m) = 0, (m = 1, 2, 3, 4). It should be noted that the preset actual data transmission start time is not limited to satisfying periodicity; it only needs to be preset by both the gNB and the UE.

[0112] By restricting the transmission timing of the actual data transmission start time, the device can only transmit actual data on the CG PUSCH resource from these preset transmission timings, thus controlling the complexity of the gNB's detection of actual data transmission on the CG PUSCH resource. If there is no data transmission at the transmission timing of an actual data transmission start time, the CG PUSCH resource will not be occupied until the next actual data transmission start time arrives. After the gNB detects actual data at the transmission timing of the actual data transmission start time and determines that the current data transmission has ended, it can choose not to detect data on the CG PUSCH configuration resource before the next actual data transmission start time. Furthermore, if the UE is limited to transmitting data only once within a cycle of the CG PUSCH configuration resource, the gNB determines that it will not detect data at other transmission timings within the same cycle after the current data transmission ends. Taking a data transmission mode combination including data transmission mode A3 as an example, transmission mode A3 refers to the actual data transmission starting at times slots 1, 5, 9, 13, 17, etc., within a cycle of the CG PUSCH resource. If the gNB does not detect actual data transmission in time slot 1, it can choose not to detect the UE's data in time slots 2 to 4. If the gNB detects actual data transmission in time slot 1 and determines the end of this data transmission in time slot 3, then it does not need to detect the UE's data in time slot 4. Similarly, if the gNB detects actual data transmission in time slot 1 and determines the end of this data transmission in time slot 7, then it does not need to detect the UE's data in time slot 8. Therefore, when the gNB's processing capacity is ample, the UE can be configured to use data transmission mode A1, which actually occupies CG PUSCH resources; when the gNB's processing capacity is limited, the UE can be configured to use data transmission mode A4, which actually occupies CG PUSCH resources. It should be noted that restricting the timing of the actual data transmission start point will affect the real-time performance of the actual data transmission. Both the gNB and the UE determine the various transmission modes and the target transmission mode based on the latency requirements of the actual data to be transmitted, the data packet size, and the gNB's processing capacity. For example, if the gNB's processing capacity can meet the data transmission latency requirements of both data transmission modes A3 and A4, but data transmission mode A3 can meet the data transmission latency requirements while data transmission mode A4 cannot, then the UE should be configured to use data transmission mode A3, which actually occupies CG PUSCH resources.

[0113] Figure 11 A schematic diagram illustrating the actual data transmission timings at multiple data transmission opportunities on the CG PUSCH configuration resource.

[0114] More preferably, the data transmission method that actually occupies CG PUSCH resources refers to the transmission timing at which the actual data transmission starts and the number of transmission timings occupied. In addition to pre-setting the transmission timing at which the actual data transmission starts, the UE and gNB also pre-setting the number of transmission timings occupied by the actual data transmission. For example... Figure 11 As shown, data transmission modes B1, B2, B3, and B4 refer to the preset number of transmission slots occupied by the actual data transmission, which are 1, 2, 3, and 4, respectively, based on the preset start time of the actual data transmission. By presetting the start time of the actual data transmission and the number of transmission slots occupied, the complexity of the gNB's detection of actual data transmission on the CG PUSCH resource can be controlled. The gNB detects data according to the preset start time of the actual data transmission. After detecting the end of the actual data transmission, it detects data sequentially according to the preset number of transmission slots occupied. Before the next start time of the actual data transmission, data on the CG PUSCH configuration resource can be ignored. For example, the UE and gNB preset the data transmission mode that actually occupies the CG PUSCH resource as B2. Transmission mode B2 means that the start time of the actual data transmission within a CG PUSCH resource cycle is in time slots 2, 7, 10, 15, etc., and the actual data sent at each start time occupies 2 transmission slots. If the gNB detects actual data transmission in time slot 2, it may not need to detect the UE's data in time slots 4 to 6 after detecting actual data transmission in time slot 3.

[0115] Figure 12 Configure the CG PUSCH resource to repeatedly send data at multiple data transmission times. This includes the actual data transmission start time and the number of repetitions for each start time.

[0116] Repeated transmissions can improve the reliability of actual data transmission on CG PUSCH resources. Due to varying reliability requirements for multiple actual data transmissions, and / or different channel transmission conditions at different transmission times on CG PUSCH resources, the number of repetitions of actual data transmitted at different transmission times on CG PUSCH resources varies. If the gNB does not know which transmission times are repeated and which are single transmissions, the gNB cannot merge the detected data to obtain merging gain during demodulation. Alternatively, the gNB needs to try various possibilities of repeated data transmissions to demodulate the data, resulting in extremely high detection complexity. By pre-setting the transmission time at which the actual data transmission starts, and the number of repetitions corresponding to each start time, the complexity of the gNB detecting actual data transmission on CG PUSCH resources can be controlled. Figure 7 As shown, data transmission methods C1, C2, C3, and C4 refer to the cases where the number of repeated transmissions of actual data is 2, 3, 4, and 5, respectively, based on the preset transmission timing of the actual data transmission start time. The preset transmission timing of the actual data transmission start time between the UE and gNB, and the number of repetitions used in the actual data transmission, allow the gNB to merge and receive repeated data when detecting actual data on the CG PUSCH resource, thereby improving the reliability of data transmission. Similar to (1), by preset transmission timing of the actual data transmission start time between the UE and gNB, and the number of repetitions corresponding to each start time, the complexity of gNB detecting actual data transmission on the CG PUSCH resource can be controlled. gNB detects data according to the preset transmission timing of the actual data transmission start time, and determines the transmission timing and detects data sequentially according to the number of repetitions corresponding to each start time. Before the next transmission timing of the actual data transmission start time, data on the CG PUSCH configuration resource may not be detected.

[0117] Similarly, it should be noted that the preset actual data transmission start time is not limited to satisfying periodicity; it is acceptable as long as both the gNB and the UE preset the actual data transmission start time.

[0118] Figure 13 Configure multiple data transmission opportunities on the CG PUSCH resource to actually send data together. This includes the start time of the actual data transmission within the specified transmission opportunity and the number of transmission opportunities combined.

[0119] The size of service data packets varies over time, with large packets being several times larger than small packets, requiring more resources on the CG PUSCH configuration transmission slot. Large packets can be divided into multiple data blocks for transmission, or they can be transmitted as a single large transmission block. Large transmission blocks, after encoding and modulation, require resources on multiple transmission slots to carry. The number of these multiple transmission slots is called the combined transmission slot number. For example... Figure 8 As shown, data transmission modes B1, B2, B3, and B4 refer to the cases where the number of transmission timing combinations corresponding to the actual data transmission is 2, 3, 4, and 5, respectively.

[0120] If there is no preset number of transmission timings between the gNB and the UE, the gNB cannot correctly demodulate the data transmitted by the UE on the CG PUSCH. By presetting the transmission timing at the actual data transmission start time and the number of transmission timings, the gNB can adjust the size of the data packets transmitted on the CG PUSCH resource to meet the transmission requirements.

[0121] Figure 14The distribution of actual data transmission formats for multiple data transmission times on the CG PUSCH configuration resource represents the correspondence between actual data transmission formats and transmission times.

[0122] The type of actual data transmission matches the service requirements. For example, if the arrival time of the service meets a preset distribution, then the transmission time occupied by the actual data transmission within the CG PUSCH transmission cycle corresponds to this preset distribution. Figure 9 In data transmission mode E1, the relative positions of the actual data transmission opportunities within the CG PUSCH transmission cycle are the same as those between time slots 2, 4, 5, 6, 9, 10, 13, 14, and 15. In data transmission mode E2, the relative positions of the transmission opportunities within the CG PUSCH transmission cycle are the same as those between time slots 4, 6, 7, 9, 10, 13, 14, 15, and 16. After the gNB detects the start of actual data transmission, it can determine which subsequent transmission opportunities within the current cycle to detect data based on the preset data transmission mode with the UE. This improves the efficiency of gNB data detection.

[0123] The data transmission method combination includes at least one transmission method. Any of these at least one transmission method can be any item among the following: the start time of actual data transmission on the first resource, the number of transmission time slots occupied by actual data transmission, the number of repetitions of actual data transmission, the combined number of transmission time slots corresponding to actual data transmission, and the actual data transmission format. For example, the data transmission method combination includes data transmission methods B2, C2, D2, and E2. The set transmission method can also be any combination of the start time of actual data transmission, the number of transmission time slots occupied by actual data transmission, the number of repetitions of actual data transmission, and the combined number of transmission time slots corresponding to actual data transmission. For example, the data transmission method combination includes data transmission methods Q1, Q2, Q3, and Q4. Transmission method Q1 sets the start time of actual data transmission, the number of transmission time slots occupied by actual data transmission at a portion of the start time, and the number of repetitions of actual data transmission at a portion of the start time.

[0124] In any embodiment of this application, the transmission frequency of the first indication information is lower than that of the second and third indication information. The first indication information is used to configure CG PUSCH resources, which has the characteristic of being configured once and used multiple times, and can meet the data transmission requirements of relatively stable cycles and traffic volumes. If the actual data corresponding to the service is quasi-periodic and the traffic volume fluctuates to a certain extent over time, the reliability requirements for data transmission are also relatively high. For example, XR services. If dynamic scheduling is used to allocate the transmission resources for this service, the burden of dynamic scheduling indication messages will be heavy, and the distribution characteristics of the service data will not play a role in the resource allocation process. If the existing CG PUSCH resource allocation method is used, the gNB will face the problems of high detection complexity and low utilization efficiency of CG PUSCH resources. Using the scheme of this embodiment, the first indication information is used to determine the first resource, that is, the uplink data transmission resource configured according to a set cycle, which contains N available data transmission opportunities in any cycle. The first resource can meet the transmission requirements of similar XR service types, but the gNB has high detection complexity and poor utilization efficiency of the first resource. The distribution of actual data transmission in any cycle of the periodic resource is determined by the second indication information, thereby determining the transmission opportunity of actual data transmission. The transmission frequency of the first indication information is lower than that of the second and third indication information. This leverages the advantages of the first resource-related configuration, which places less burden on configuration information during CG PUSCH resource allocation and offers better real-time resource utilization. Furthermore, determining the second resource through the set transmission method can mitigate the high complexity of gNB detection and the low efficiency of CG PUSCH resource utilization. Before the second indication information is updated, both the gNB and the UE consider the first indication information unchanged. Thus, a balance can be struck between indicators such as service data transmission latency, reliability, gNB detection complexity, and CG PUSCH resource utilization efficiency by adjusting the transmission frequency of the second indication information, the set transmission method, and the selected target transmission method.
