In the current R16 protocol version, for the semi-persistent scheduling SPS, although multiple SPS configurations are supported, only one SPS can be activated at a time. When multiple SPS configurations need to be activated, multiple DCI commands need to be sent, and the activation instructions are shown in Table 1 (the DCI scrambled is the Configured Scheduling-Radio Network Tempory Identity (CS-RNTI)) .

Table 1 Activates the DCI field settings of an SPS configuration (CS-RNTI scrambled DCI)

The parameters of RRC configuring SPS are shown in Table 2.

A single SPS configuration is performed based on the TDRA mode of the existing RRC signaling configuration. The TDRA table used is a general (dynamic scheduling and SPS scheduling shared) TDRA table. In the table, each row only contains an effective start and length indication value ( Start and Length Indicator Value, SLIV), as shown in Table 3. In the discussion of R17, the standard decided to support the function that one DCI can schedule up to 8 PDSCHs at the same time in the high frequency (the number of PDSCHs to be scheduled is determined by the base station). On the one hand, for the existing method of SPS scheduling, it is impossible to activate or retransmit multiple PDSCHs with one DCI; on the other hand, if the dynamic scheduling method supports one DCI to schedule multiple PDSCHs, the SPS scheduling method does not support one DCI activation or retransmission Multiple PDSCHs, and still use the existing common TDRA table configuration method, you need to reserve "only one SLIV" time-domain scheduling row for SPS in the table, that is, the table should reserve configuration rows for single and multiple PDSCH scheduling at the same time , considering the limitation of the table length (determined by the length of the TDRA field of DCI, currently 4 bits), this greatly limits the flexibility of PDSCH scheduling. Therefore, how to support one DCI to activate or retransmit multiple PDSCHs under the SPS scheduling method, or how to take into account the PDSCH dynamics when the dynamic scheduling supports one DCI to schedule multiple PDSCHs but only supports one DCI to activate or retransmit one PDSCH under the SPS scheduling method The flexibility of scheduling and SPS activated retransmission is an important issue that the industry needs to solve urgently. Based on this, various embodiments of the present disclosure provide a solution, by improving the TDRA mode of RRC signaling configuration, combined with the Time domain resource assignment time domain information in DCI signaling, and flexibly through explicit or implicit methods This problem can be solved by directly instructing the SLIV of the SPS configuration.

Then, the first HARQ process number is assigned to the first one of the multiple PDSCHs scheduled by one SPS (corresponding to the first SLIV among the multiple effective SLIVs determined, the first PDSCH uses the first SLIV PDSCH, follow-up PDSCH is the same), and the HARQ process number corresponding to the previous PDSCH plus 1 is allocated to the next PDSCH in turn, until multiple PDSCHs scheduled by one SPS are all allocated with HARQ process numbers. For example, there are 4 SLIVs in total, and the PDSCH corresponding to SLIV 1 is assigned the first HARQ process number 1 (assuming that the calculation result of the first HARQ process number is 1), then the HARQ process number assigned to the PDSCH corresponding to SLIV 2 is 2, The HARQ process number assigned to the PDSCH corresponding to SLIV 3 is 3, and the HARQ process number assigned to the PDSCH corresponding to SLIV 4 is 4.

Finally, if it is determined that the number of allocated HARQ processes is less than the maximum number of HARQ processes nrofHARQ-Processes, for example, the maximum number of HARQ processes is 8, and the number of HARQ processes allocated for one round is 4, then the last allocated HARQ process needs to be allocated The process number plus 1 is allocated to the first of multiple PDSCHs scheduled by SPS, that is, a HARQ process number 5 is allocated to the PDSCH corresponding to SLIV 1, and the above allocation operation is repeated until the number of allocated HARQ processes is equal to the maximum number of HARQ The number of processes is to allocate a HARQ process number 6 for the PDSCH corresponding to SLIV 2, a HARQ process number 7 for the PDSCH corresponding to SLIV 3, and a HARQ process number 8 for the PDSCH corresponding to SLIV 4.

Among them, the preset rules include:

If it is determined that a dedicated TDRA table for SPS scheduling is configured, select the dedicated TDRA table for SPS scheduling as the TDRA table for the time domain information index; or,

If it is determined that the dedicated TDRA table for SPS scheduling is not configured, the general TDRA table is selected as the TDRA table for the time domain information index, and the general TDRA table is the second TDRA table.

Specifically, before searching the TDRA table based on the time domain information, the terminal may determine whether to use the SPS scheduling dedicated TDRA table or the general TDRA table as the TDRA table for the time domain information index based on preset rules. According to the preset rules, the terminal preferentially uses the TDRA table dedicated for SPS scheduling as the TDRA table for time domain information index, that is, if it is determined that the TDRA table dedicated for SPS scheduling is configured, then select the TDRA table dedicated for SPS scheduling as the TDRA table for time domain information index, SPS The scheduling-specific TDRA table can be the first TDRA table with only one valid SLIV configured for each row, or the second TDRA table with at least one row configured with two or more valid SLIVs; if it is determined that no SPS scheduling-specific TDRA table is configured, Then select the general TDRA table as the TDRA table of the time domain information index. In the embodiment of the present disclosure, the general TDRA table as the time domain information index is a TDRA table with at least one row configured with two or more effective SLIVs, that is, the second TDRA surface.

See Table 9 below (Yes means configured, No means not configured).

See Table 11 below (Yes means configured, No means not configured).

Embodiment 2A: Each DCI activates or retransmits an SPS configuration (including multiple PDSCHs)

In this embodiment, when the configured SPS is activated or scheduled for retransmission, the time domain information index indicated by its scheduling signaling DCI is a TDRA table with at least one row configured with two or more valid SLIVs, No matter whether the base station configures the single PDSCH scheduling TDRA table or not.

Then, when the UE receives the SPS activation or retransmission scheduling signaling (using CS-RNTI as DCI scrambling), the UE considers that the pdsch-TimeDomainAllocationList_forMultiPDSCH type table is always used as the TDRA table of the time domain information index. The TDRA table can be specially configured for SPS, or can be shared with dynamic scheduling, and the TDRA table dedicated for SPS scheduling is preferentially used. For details, see Table 13 below (Yes means configured, No means not configured).

Embodiment 3: Each DCI activates or retransmits a HARQ process ID (process number) configuration method of an SPS configuration (including multiple PDSCHs)

Step 1. Configure the maximum number of HARQ processes nrofHARQ-Processe in DCI.

Step 2, configure the HARQ process ID offset value harq-ProcID-Offset-r16 of the PDSCH in the DCI.

Step 3. The UE calculates the HARQ process number of the first PDSCH (corresponding to SLIV1) according to the offset value of the HARQ process number.

Step 4. The HARQ process number of each PDSCH is obtained by adding 1 to the HARQ process number of the PDSCH of the previous SLIV.

When the last effective SLIV is calculated, if the number of HARQ processes does not reach the maximum number of HARQ processes nrofHARQ-Processes, the HARQ process number will be added sequentially from the PDSCH of the first SLIV until the maximum number of HARQ processes is reached.

For example, suppose a total of 4 PDSCHs are configured for SPS scheduling, corresponding to SLIV1~SLIV4 respectively, the HARQ process number calculated according to harq-ProcID-Offset-r16 (that is, the first HARQ process number) is 1, and the maximum number of processes nrofHARQ-Processes is 8 , the configuration of the HARQ process number is shown in Table 15 below.
