Description

Technical Field

[0001] The present application relates to the field of wireless communication technology, and in particular to a method and device for data transmission in a wireless communication system. Background Art

[0002] SPS (Semi-Persistent Scheduling) scheduling and configured grant (CG) PUSCH scheduling allow PDSCH / PUSCH resources to be periodically allocated to a specific UE through a physical downlink control channel scheduling.

[0003] The HARQ process ID of the SPS PDSCH / configured PUSCH is determined based on the pre-configured resource location of the data transmission. Although there are multiple data transmission opportunities in a configuration period, the HARQ ID obtained by the actual transmission block is the same regardless of which transmission opportunity it occupies in a configuration period.

[0004] The arrival of XR service packets is periodic, but the actual arrival time of the packets may experience jitter, causing them to arrive randomly within the jitter time window. Therefore, unlike the prior art where the SPS configuration / CG PUSCH only includes one data transmission opportunity in one cycle, in order to meet the characteristics of XR service arrival time jitter, multiple data transmission opportunities can be configured in one cycle of the SPS configuration / configuration authorization PUSCH to meet the requirement that the service packets can be sent in time after arrival.

[0005] In addition, the data packet size for XR services may vary over time, sometimes the data packet is large, and sometimes the data packet is small. Based on the SPS configuration / CG PUSCH including multiple SPS PDSCH / PUSCH transmission opportunities in one cycle, the number of PDSCH / PUSCH occupied by the data packet is determined by the size of the data packet.

[0006] If the HARQ process ID is determined according to the prior art method, the HARQ process ID corresponding to multiple SPS PDSCH / PUSCH transmission opportunities within an SPS / CG PUSCH cycle is the same. If the multiple SPS PDSCH / PUSCH are used to transmit different transport blocks, the HARQ process management will be disordered. For example, the PUSCH at time t1 and time t2 uses the same HARQ process ID, but transmits different transport blocks. Then, the data storage space of the HARQ process ID will be replaced by data block TB2 at time t2 instead of data block TB1 at time t1, resulting in TB1 being unable to realize retransmission data merging. Summary of the invention

[0007] The present application proposes a method and device for data transmission in a wireless communication system.

[0046] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in combination with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0047] The technical solutions provided by various embodiments of the present application are described in detail below in conjunction with the accompanying drawings.

[0048] Figure 1 An example of the periodic configuration of resources in the prior art is given.

[0049] SPS (Semi-Persistent Scheduling) scheduling and configured grant (CG) PUSCH scheduling allow PDSCH / PUSCH resources to be periodically allocated to a specific UE through a physical downlink control channel scheduling. The specific process of SPS scheduling is that the base station uses the PDCCH scrambled by CS-RNTI to specify the wireless resources used by the UE (here it is called SPS PDSCH resources). After each period, the UE uses the SPS PDSCH resources to receive or send data, and the base station does not need to send PDCCH to specify the allocated resources. There are two ways to transmit CG PUSCH configuration: one is CGPUSCH type 1, and the resources for transmission authorization are all provided by RRC. The UE stores the configuration and uses it as a grant configuration when there is uplink data transmission. The other is CG PUSCH type 2, and the RRC layer configures the CG PUSCH period, HARQ sequence number and other information, and then the physical downlink control channel PDCCH activates or deactivates the configuration. The PDCCH for activating or deactivating the CG PUSCH contains the resources occupied by the PUSCH in time and frequency, as well as the time position of the first CG PUSCH. After obtaining the activation information, the UE can use the CG PUSCH resources.

[0050] For example, Figure 1 This is a schematic diagram of 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. Similar to CG PUSCH type 2, the SPS PDSCH is also configured by the base station through RRC, including the period, HARQ sequence number, and other information of the SPS PDSCH, and then the PDCCH activates or deactivates the configuration.

[0051] The HARQ process ID of the SPS PDSCH / configured authorized PUSCH is determined based on the pre-configured resource position of the data transmission. Still taking the configured authorized PUSCH as an example, the configuration information includes the configured authorization period, the number of HARQ processes used by the configured authorized PUSCH, etc. The HARQ process ID used for a PUSCH transmission is determined by the first symbol position of the PUSCH, specifically:

[0052] HARQ process ID = [floor (X / cycle)] modulo Y, where:

[0053] X = (system frame number × number of consecutive time slots per frame × number of consecutive symbols per time slot + time slot index in the current frame × number of consecutive symbols per time slot + symbol index in the current time slot);

[0054] Y is the number of HARQ processes configured to be used by the authorized PUSCH;

[0055] Floor is the rounding operation, and modulo is the modulo operation.

[0056] If the configuration information indicates that the transmission block is sent repeatedly on the PUSCH of the configuration authorization, the same HARQ process ID is used for the multiple repeated transmissions. The above "symbol index in the current time slot" refers to the first symbol index of the first PUSCH transmission opportunity. That is, the HARQ process ID is mainly determined based on the time of the transmission opportunity configured for the UE for uplink data transmission.

[0057] Likewise, when the SPS PDSCH is transmitted, the HARQ process ID is determined by the time of the transmission opportunity of the downlink data transmission.

[0058] Figure 2 (a) to (b) are schematic diagrams of the mapping relationship between XR service packets and transmission opportunities, where (a) multiple data transmission opportunities are configured under jitter conditions, and (b) the size of the data packet changes;

[0059] The arrival of packets for XR services is periodic, but the actual arrival time of the packets may experience jitter, causing their arrival time to arrive randomly within the jitter time window. Figure 2(a) is an example, in which the first jitter time window starts at time t0, where an XR data packet can arrive within this time window between t0 and t4, and the XR data packet in the figure arrives at time t1. The next XR data packet arrives after time P, and the next XR data packet can arrive at any time within the jitter time window between t5 and t9. In the figure, the next XR data packet arrives at time t7. Therefore, unlike the prior art in which the SPS configuration / CG PUSCH only includes one data transmission opportunity in one cycle, in order to meet the characteristics of the XR service arrival time jitter, multiple data transmission opportunities can be configured within one cycle of the SPS configuration / configuration authorization PUSCH to meet the requirement that the service packet can be sent in time after arrival.

[0060] In addition, the data packet size for XR services may vary over time, sometimes the data packet is large, and sometimes the data packet is small. Based on the SPS configuration / CG PUSCH including multiple SPS PDSCH / PUSCH transmission opportunities in one cycle, the number of PDSCH / PUSCH occupied by the data packet is determined by the size of the data packet. As shown in Figure 2(b), in the first cycle of CG PUSCH, the XR data packet occupies 3 PUSCHs to transmit TB1, TB2, and TB3 respectively. In the next cycle of CGPUSCH, the XR data packet occupies 1 PUSCH to transmit TB4. It can also be said that the XR service meets the quasi-periodic characteristics. Quasi-periodic data refers to the burst window of the data that meets the periodicity. For example, a jitter window length is L, the burst window is composed of multiple jitter windows with a period of P, and the data burst occupies part or all of the data transmission opportunities of the jitter window.

[0061] Figure 3 This is a flow chart of an embodiment of the method of this application;

[0062] In an embodiment of the first aspect, the present application provides a wireless communication system data transmission method, comprising the following steps 110-140:

[0063] Step 110: Determine periodic configuration resources, where each period includes N data transmission opportunities, and each data transmission opportunity is used for one transmission block.

[0064] Preferably, the configuration information includes a maximum value of M.

[0065] Step 120: In the i-th cycle, determine M actual data transmissions corresponding to the M data transmission opportunities occupied by the data.

[0066] Preferably, resources of the M actual data transmission opportunities are sequentially adjacent in time.

[0067] Step 130: Determine the HARQ process ID of the M actual data transmissions, where the process ID of the jth actual data transmission is j It has a one-to-one correspondence with j, j=1~M, M>1.

[0068] Preferably, the method described in any embodiment of the present application determines the basic HARQ process number corresponding to the i-th cycle, and the process number ID of the j-th actual data transmission is j It is jointly generated by the basic HARQ process number and j.

[0069] For example, the basic HARQ process number of the i-th period is determined by the time position of the first data transmission opportunity of the N data transmission opportunities.

[0070] For another example, the HARQ process number of the j-th actual data transmission is the sum of the basic HARQ process number and j.

[0071] It should be noted that the "one-to-one correspondence" relationship in this application refers to the unique correspondence between the elements of two sets, which is generally one-to-one, that is, one-to-one mapping. As two sets A and B, each element in B has an original image, and different elements in set A have different images in set B, then a one-to-one correspondence relationship between sets A and B is established, that is, a one-to-one mapping.

[0072] Step 140: Identify the M actual data transmissions in the i-th cycle according to the determined HARQ process number.

[0073] Preferably, the j-th opportunity data transmission includes control information, and the control information is used to determine the value of j.

[0074] In the present application, the transmission channel for realizing the actual data transmission may be SPS PUSCH, SPS PDSCH or CGPUSCH.

[0075] It should be noted that the above steps are used for network entities of a wireless communication system, including terminal-side devices, network-side devices, intermediate devices or other high-level service devices; the above steps can also be used for service devices that provide information processing for the network entity devices; 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-side devices or network-side devices.

[0076] The method of the present application can be used for data information between a first device (gNB) and a second device (UE).

[0077] FIG4 (a) to (b) are schematic diagrams of HARQ identification of timing data transmission for carrying XR data packets implemented in the present application, wherein (a) non-actual data transmission participates in HARQ ID numbering, and (b) non-actual data transmission does not participate in HARQ ID numbering;

[0078] Taking N (N≥2) PUSCH transmission opportunities within a CG PUSCH period as an example, using the prior art, the floor(X / period) corresponding to these N PUSCHs is the same. Correspondingly, the N PUSCH transmission opportunities correspond to the same HARQ process ID. Assuming that there is always only one actual PUSCH transmission among the N PUSCH transmission opportunities, the prior art can be used to determine its HARQ process ID. However, under the dual influences of the jitter in the arrival time of data packets for XR services and the variable amount of information in data packets, the possible number of actual PUSCH transmissions among the N PUSCH transmission opportunities is M, where 1≤M<N. If different HARQ process IDs are always assigned to the N PUSCH transmission opportunities respectively, it will result in high complexity and low efficiency in HARQ process management. As shown in Fig. 4(a), N = 4. If the HARQ process IDs corresponding to the 4 PUSCH transmission opportunities at t0, t1, t2, and t3 are 0, 1, 2, and 3 respectively, and the actual PUSCH transmissions only occur at t1, t2, and t3, but in order to avoid the possibility of data packets arriving at t0 and using HARQ process #0, the base station needs to ensure the release of the use of HARQ process #0 before t0. Similarly, the base station needs to ensure the release of the use of HARQ processes #1, #2, #3, #0, #1, #2, and #3 before t1, t2, t3, t4, t5, t6, and t7 respectively, which will affect both the flexibility and efficiency of scheduling. Similarly, if a HARQ process number is assigned to each PUSCH transmission opportunity regardless of whether there is an actual PUSCH transmission, it takes a certain period of time after the semi-statically configured transmission opportunity to ensure that the assigned HARQ process number is released and can be used for dynamic scheduling.

[0079] The inventive concept of this application is that when configuring CG PUSCH resources, there are N (N≥2) PUSCH transmission opportunities within a CG PUSCH period, corresponding to 1≤M≤N actual PUSCH transmissions. The HARQ process ID corresponding to the j-th actual PUSCH within the CG PUSCH period is determined by j. As shown in Fig. 4(b), in the first period, the 1st, 2nd, and 3rd actual PUSCH transmissions at t1, t2, and t3 correspond to TB1, TB2, and TB3, and the HARQ process IDs are #x, #x + 1, and #x + 2 respectively.

[0080] Similarly, the HARQ process IDs corresponding to multiple PDSCH transmissions within an SPS period are determined by the numbers of actual PDSCH transmissions within the SPS period.

[0081] Figure 5 Flowchart of the method of this application for the embodiment of the network-side device.

[0082] The method described in any embodiment of the first aspect of this application, which is used for a network-side device, includes the following steps 210 to 240:

[0083] Step 210: Send configuration information, where the configuration information is used to determine periodic configuration resources. Each period contains N data transmission opportunities, and each data transmission opportunity is used for 1 transport block.

[0084] Step 220: In the i-th period, determine M actual data transmissions corresponding to the M data transmission opportunities occupied by the data.

[0085] For the N transmission opportunities, there are 1 ≤ M ≤ N actual data transmissions. Or, there are at least one period in the periodic configuration resources with M transmission opportunities, 1 < M ≤ N. Or, there are at least one period in the periodic configuration resources with M transmission opportunities, 1 < M < N.

[0086] Step 230: Determine the HARQ process numbers of the M actual data transmissions, where the process number ID of the j-th actual data transmission j has a one-to-one correspondence with j, j = 1 to M, M > 1.

[0087] Preferably, determine the base HARQ process number corresponding to the i-th period. The HARQ process number of the first actual data transmission is the base HARQ process number, and the HARQ process number of the j-th (1 ≤ j ≤ M) actual data transmission is determined by j and the base HARQ process number.

[0088] Step 240: Identify the M actual data transmissions in the i-th period according to the determined HARQ process numbers.

[0089] Figure 6 Flowchart of the embodiment of the method of this application for a terminal-side device.

[0090] The method described in any embodiment of the first aspect of this application, which is used for a terminal-side device, includes the following steps 310 to 340:

[0091] Step 310: Obtain configuration information, where the configuration information is used to determine periodic configuration resources. Each period contains N data transmission opportunities, and each data transmission opportunity is used for 1 transport block.

[0092] Optionally, the periodic configuration resources are SPS resources or configured grant PUSCH.

[0093] Optionally, the configuration information includes the maximum value of M.

[0094] Step 320: In the i-th period, determine M actual data transmissions corresponding to the M data transmission opportunities occupied by the data.

[0095] The N transmission opportunities have 1≤M≤N actual data transmissions,

[0096] Optionally, resources of transmission opportunities of the M actual data transmissions are adjacent to each other in time.

[0097] Step 330: Determine the HARQ process ID of the M actual data transmissions, where the process ID of the jth actual data transmission is j It has a one-to-one correspondence with j, j=1~M, M>1.

[0098] Determine the basic HARQ process number corresponding to the i-th cycle;

[0099] The HARQ process number of the first actual data transmission is the basic HARQ process number, and the HARQ process number of the j-th (1≤j≤M) actual data transmission is determined by j and the basic HARQ process number;

[0100] Optionally, the basic HARQ process number of the i-th period is determined by the time position of the first transmission opportunity of the N transmission opportunities, for example but not limited to using formula (1).

[0101] Optionally, the HARQ process number of the j-th actual data transmission is equal to the sum of the basic HARQ process number and j.

[0102] Step 340: Identify the M actual data transmissions in the i-th cycle according to the determined HARQ process number.

[0103] The M actual data in the ith period are transmitted correspondingly according to the determined HARQ process number. Optionally, the jth actual data transmission includes control information, and the control information is used to determine the value of j.

[0104] In this embodiment, the configuration information is used to determine the periodic configuration resources. For example, the configuration information includes an SPS configuration message and scheduling information for activating the SPS configuration. Alternatively, the configuration information is an RRC message corresponding to CG PUSCH type 1. Alternatively, the configuration information is an RRC message corresponding to CG PUSCH type 2 and a message for activating CG PUSCH type 2. In this embodiment, the periodic configuration resources refer to a number of resources with a period of P. Each period includes N data transmission opportunities. Accordingly, each data transmission opportunity has a corresponding transmission resource.

[0105] In each cycle, the transmission resources corresponding to the N data transmission opportunities may or may not have actual data transmission. According to the prior art, the HARQ process number is determined as follows:

[0106] HARQ process ID = [floor (X / cycle)] modulo Y (1)

[0107] The HARQ process numbers corresponding to the N data transmission opportunities are the same. In this embodiment, the basic HARQ process numbers corresponding to the configured resource periods in which the multiple data transmission opportunities are located are first determined. The HARQ process number of the actual data transmission is determined based on the basic HARQ process number. As an implementation method, the basic process number corresponding to the i-th period can be determined by the time position of the K-th (K≤N) transmission time in the N data transmission opportunities. K is preset. Preferably K=1. For example, the basic HARQ process number can be determined using formula (1) and the time position of the K-th data transmission opportunity. For example, the basic HARQ process number corresponding to the i-th period is determined to be x.

[0108] The basic HARQ process number corresponding to the i-th cycle is x, which is used to determine the HARQ process number corresponding to the actual data transmission in the i-th cycle. In the N transmission opportunities of the i-th cycle, there are M (1≤M≤N) actual data transmissions. Among them, the HARQ process number of the first actual data transmission is the basic HARQ process number, and the HARQ process number of the j-th (1≤j≤M) actual data transmission is determined by j and x. The process number ID of the j-th actual data transmission is j The basic HARQ process number and j can be used to jointly generate a unique process number ID for the jth actual data transmission. j For example, the HARQ process number of the jth actual data transmission is j+x. When the M actual data are transmitted in the i-th cycle, the HARQ process numbers corresponding to each other may be used.

[0109] Since the network adopts a stop-and-wait mode in which multiple HARQ processes are parallel, each HARQ process number corresponds to its own storage space for multiple retransmissions and merging. A HARQ process number can be used for data transmission on periodically configured resources and for dynamically scheduled data transmission. In order to avoid data transmissions with the same HARQ process number from overlapping each other, the data that first uses the HARQ process number should complete the predetermined retransmission and merging before the HARQ process number is used for subsequent data transmission. This embodiment breaks the conventional practice that the HARQ process number for data transmission on periodically configured resources is determined by the time position of the resource. In the case where there are N data transmission opportunities for a periodically configured resource, there are M (1≤M≤N) actual data transmissions, and the actual occupied HARQ process numbers are also M. Compared with occupying N HARQ process numbers, the HARQ process number multiplexing complexity for data transmission on periodically configured resources and dynamically scheduled data transmission is lower and more efficient.

[0110] Preferably, the configuration information includes a maximum value of M. In this way, the maximum number of HARQ processes and HARQ process numbers used in one cycle of the configured resources can be determined as early as possible, so as to facilitate sharing of the HARQ process number with dynamically scheduled data transmission. Optionally, the resources of the transmission opportunities of the M actual data transmissions are adjacent to each other in time.

[0111] In this embodiment, the HARQ process number of the jth (1≤j≤M) actual data transmission is determined by j and the basic HARQ process number. In order to avoid the sender and receiver of the data transmission having different determination results for the value of j for one data transmission, the jth actual data transmission may include control information, and the control information is used to determine the value of j. The data receiver can determine the value of j corresponding to the actual data transmission according to the control information, and then determine the HARQ process number of this data transmission.

[0113] An embodiment of the present application also proposes a network side device, using the method of any one of the embodiments of the present application, at least one module in the network side device is used for at least one of the following functions: determining the periodic configuration resources, determining the M data transmission opportunities in the i-th period; determining the HARQ process number of the M actual data transmissions; sending the configuration information; receiving the CG PUSCH identified by the HARQ process number; and sending the SPSPDSCH identified by the HARQ process number.
