The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.

In the embodiments of the present application, the term "plurality" means two or more, and other terms are similar thereto.

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

In the existing R16 protocol version, for semi-persistent scheduling SPS, although configuration of multiple SPS is supported, only one SPS can be activated at a time. When a plurality of SPS configurations need to be activated, a plurality of DCI commands need to be transmitted, and the activation indication is as shown in table 1 (where DCI is scrambled by CS-RNTI (Configured Scheduling-Radio Network temporary Identity)).

The parameters of the RRC configuration SPS are shown in table 2.

A single SPS is configured based on a TDRA mode configured by an existing RRC signaling, a used TDRA table is a general (shared by dynamic scheduling and SPS scheduling) TDRA table, and each row in the table only contains one valid SLIV (Start and Length Indicator Value, start and Length information Value), as shown in table 3. In the discussion of R17, the standard decides to support the function that one DCI in high frequency can schedule 8 PDSCHs at most simultaneously (the number of specifically scheduled PDSCHs is decided by the base station). On one hand, for the existing SPS scheduling mode, one DCI can not be activated or a plurality of PDSCHs can not be retransmitted; on the other hand, if one DCI is supported to schedule multiple PDSCHs for the dynamic scheduling mode, and one DCI is not supported to activate or retransmit multiple PDSCHs for the SPS scheduling mode, and the existing general TDRA table configuration mode is still used, a time domain scheduling row of "only one SLIV" needs to be reserved for the SPS in the table, that is, the table needs to simultaneously reserve configuration rows for scheduling single and multiple PDSCHs, considering the table length limitation (determined by the length of the TDRA field of the DCI, currently 4 bits), which greatly limits the flexibility in scheduling the PDSCHs. Therefore, how to support the DCI activation or retransmission of multiple PDSCHs in the SPS scheduling manner or how to support the DCI activation or retransmission of multiple PDSCHs in the SPS scheduling manner, and how to allow the base station to consider the flexibility of the PDSCH dynamic scheduling and the SPS activation retransmission when only one DCI activation or retransmission is supported in the SPS scheduling manner, is an important issue to be solved in the industry. Based on this, embodiments of the present application provide a solution, which can solve the problem by improving a TDRA manner configured by an RRC signaling, combining Time domain resource assignment Time domain information in a DCI signaling, and flexibly indicating an SPS configured SLIV in a display or implicit manner.

and searching a second TDRA table based on the column index indicated by the time domain information and the row index indicated in the RRC signaling, and determining SLIV used by single PDSCH transmission scheduled by SPS once.

and searching a second TDRA table based on the row index indicated by the time domain information, and determining the first effective SLIV in the row indicated by the row index as the SLIV used by the single PDSCH transmission scheduled by the SPS once.

Specifically, for the situation that a single PDSCH is scheduled by SPS for one time, the network device may also indicate the row index only by using the time domain information, and when the terminal searches the second TDRA table, the first valid SLIV in the row indicated by the row index is determined as the SLIV used for transmission of the single PDSCH scheduled by SPS this time by default.

and searching the SLIV set based on the element positions in the set indicated by the time domain information, and determining SLIV used by single PDSCH transmission scheduled by SPS once.

Specifically, for the case of scheduling a single PDSCH by an SPS once, when searching for the second TDRA table, the terminal may determine M (M is greater than or equal to 1) different effective SLIVs from the second TDRA table according to a certain order (for example, the order of preceding column and following column or the order of preceding column and following row), generate one SLIV set from the M effective SLIVs, search the SLIV set according to the element position in the set indicated by the time domain information, and determine the SLIV used for transmitting the single PDSCH by the SPS this time.

and if the number of the allocated HARQ processes is determined to be less than the maximum number of the HARQ processes, the number of the allocated last HARQ process is added with 1 to be allocated to the first PDSCH of the SPS scheduling once, and the allocation operation is repeated until the number of the allocated HARQ processes is equal to the maximum number of the HARQ processes.

Specifically, in this embodiment of the present application, after determining SLIVs used for transmission of multiple PDSCHs in SPS scheduling this time, the terminal may further determine HARQ process number configuration of each PDSCH in SPS scheduling this time according to the HARQ process number configured by the DCI and the determined number of SLIVs, where the process is as follows:

first, a first HARQ process number is calculated according to a HARQ process number Offset value HARQ-ProcID-Offset-r16 in DCI signaling.

Then, the first HARQ process number is allocated to the first PDSCH of the SPS scheduling (corresponding to the first SLIV of the determined multiple effective SLIVs, the first PDSCH uses the PDSCH of the first SLIV, and the same applies to the subsequent PDSCH), and the HARQ process number corresponding to the previous PDSCH is sequentially added with 1 to be allocated to the subsequent PDSCH, until the multiple PDSCHs of the SPS scheduling are all allocated with HARQ process numbers. For example, the number of SLIVs is 4, the PDSCH corresponding to SLIV1 is assigned with the first HARQ process number 1 (assuming that the calculation result of the first HARQ process number is 1), 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 SLIV4 is 4.

Finally, if it is determined that the number of the allocated HARQ Processes is less than the number of the HARQ maximum Processes nroflharq-Processes, for example, the number of the HARQ maximum Processes is 8, and the number of the allocated HARQ Processes for one round is 4, the allocated last HARQ process number plus 1 is allocated to the first PDSCH of the SPS scheduling, that is, one HARQ process number 5 is reallocated to the PDSCH corresponding to SLIV1, the above allocation operation is repeated until the number of the allocated HARQ Processes is equal to the number of the HARQ maximum Processes, that is, one HARQ process number 6 is reallocated to the PDSCH corresponding to SLIV 2, one HARQ process number 7 is reallocated to the PDSCH corresponding to SLIV 3, one HARQ process number 8 is reallocated to the PDSCH corresponding to SLIV4, and the number of the allocated HARQ Processes is equal to the number of the HARQ maximum Processes, then the HARQ process number allocation is ended.

and if the SPS scheduling special TDRA table is determined not to be configured, selecting the general TDRA table as a TDRA table of the time domain information index, wherein the general TDRA table is a second TDRA table.

Specifically, the terminal may determine whether to use the SPS scheduling dedicated TDRA table or the general TDRA table as the TDRA table of the time domain information index based on a preset rule before looking up the TDRA table based on the time domain information. According to a preset rule, the terminal preferentially uses an SPS scheduling special TDRA table as a TDRA table of a time domain information index, namely if the SPS scheduling special TDRA table is determined to be configured, the SPS scheduling special TDRA table is selected as the TDRA table of the time domain information index, the SPS scheduling special TDRA table can be a first TDRA table only configured with one effective SLIV in each line, and can also be a second TDRA table configured with two or more effective SLIVs in at least one line; and if the special TDRA table for SPS scheduling is determined not to be configured, selecting the universal TDRA table as a TDRA table of the time domain information index.

step 200, starting;

step 201, sending a downlink control information DCI signaling to the terminal, where the DCI signaling includes time domain information used to indicate a start of SPS configuration and a length information value, SLIV, index.

Specifically, in this embodiment, when a network device (e.g., a base station) determines that SPS activation or retransmission scheduling needs to be performed, a DCI signaling (DCI scrambling is performed using a CS-RNTI) may be sent to a terminal (e.g., a UE), where the DCI signaling includes time domain information used to indicate an SLIV index used for SPS configuration, that is, the network device may indicate, through the time domain information in the DCI signaling, the SLIV index used for SPS configuration, where the SLIV index may be a row index or a column index of a TDRA table, or may be an SLIV index of any other form, which is not limited herein.

After the terminal receives the DCI signaling sent by the network device, the terminal may find a TDRA table (a first TDRA table or a second TDRA table) configured to the terminal by the network device based on time domain information included in the DCI signaling, and determine the SLIVs used for SPS configuration, which include the SLIVs used for transmitting a single PDSCH scheduled by SPS once or the SLIVs used for transmitting multiple PDSCHs scheduled by SPS once.

In the SPS configuration method provided in this embodiment, the network device sends the DCI signaling to the terminal, and indicates, through the time domain information, the SLIV index used for SPS configuration, so that the terminal may search the TDRA table based on the time domain information in the DCI signaling, and determine the SLIV used for transmitting a single or multiple PDSCH scheduled by SPS once, thereby improving the flexibility of SPS scheduling PDSCH.

Optionally, the method further comprises:

and sending radio resource management (RRC) signaling to the terminal, wherein the RRC signaling indicates a row index or a column index used by the SPS configuration.

Specifically, in this embodiment of the present application, the network device may further indicate, to the terminal through an RRC signaling, a row index or a column index used by the SPS configuration, so that when the terminal searches the second TDRA table, according to a common indication of the RRC signaling and the time domain information, the network device determines the SLIV used for transmitting the single PDSCH scheduled by the SPS once. For example, the network device may indicate a row index and a column index through time domain information and RRC signaling, respectively, or indicate a column index and a row index, respectively, so that the terminal may look up the second TDRA table according to the row index and the column index to determine the SLIV used for a single PDSCH transmission scheduled by SPS.

Specifically, for the case where multiple PDSCHs are scheduled for SPS at one time, the network device may define the meaning of the fields in the DCI signaling as shown in table 4 below.

Wherein, each 1 bit of RV field in DCI signaling corresponds to RV of PDSCH data packet scheduled by 1 SPS; each 1 bit of the NDI field in the DCI signaling corresponds to the NDI of 1 SPS scheduled PDSCH packet. When SPS retransmission is performed, NDI of all SPS scheduled PDSCH data packets is defined to be 1.

In this embodiment, when the configured SPS is activated or performs scheduling retransmission, the time domain information index indicated by the scheduling signaling DCI is the SPS scheduling dedicated TDRA table in which all rows have only one effective SLIV, and no matter the general TDRA table configured by the base station is the TDRA table in which all rows have only one effective SLIV or the scheduling TDRA table of multiple PDSCHs.

For example: the base station is configured with 1 or more TDRA tables, wherein all rows of the tables of the pdsch-TimeDomainAllocationList type only have one effective SLIV; or, the base station configures 1 or more TDRA tables, wherein at least one row of the pdsch-timedomain allocation list-for-multicopdsch type table configures two or more effective SLIVs.

Then, when the UE receives the SPS activation or retransmission scheduling signaling (DCI scrambling with CS-RNTI), the UE considers that the pdsch-timedomainallclositionlist for SPS table is always adopted as the TDRA table of the time domain information index. See table 5 below (Yes for configuration and No for non-configuration).

Table 5 TDRA table usage rules in example 1A

Step 1, a dedicated TDRA table for SPS scheduling is set, and the table is characterized in that each row has only one SLIV, as shown in table 6 below.

Table 6 TDRA table for SPS in example 1A

Row index	K0	SLIV
			0	1	S＝2；L＝12
1	1	S＝2；L＝8
			2	1	S＝4；L＝7

And 2, when the DCI uses the CS-RNTI for scrambling, the UE searches the table.

Step 3, if the Row index configured by the Time domain resource assignment of the DCI is 0, the UE determines that the SPS configuration uses S =2; l =12 SLIV.

Example 1B: one SPS configuration (comprising only one PDSCH) is activated or retransmitted per DCI

In this embodiment, when the configured SPS is activated or performs scheduling retransmission, the time domain information index indicated by the scheduling signaling DCI is a specific row or a specific column of the general TDRA table pdsch-timedomainnalockationlist _ for multicopdsch, where at least one row is configured with two or more valid SLIVs. Its particular row or particular column is configured by higher layer messages, as indicated in the SPS configuration message.

For example: the base station is configured with 1 or more TDRA tables, wherein all rows of the pdsch-TimeDomainAllocationList only have one effective SLIV; or, the base station configures 1 or more TDRA tables, wherein at least one row of the pdsch-timedomainalloceationlist-for-multicopdsch is configured with two or more effective SLIVs.

Then, when the UE receives the SPS activation or retransmission scheduling signaling (DCI scrambling with CS-RNTI), the UE considers that a specific row or a specific column of the pdsch-time domain allocation list _ for the TDRA table of the time domain information index is adopted. See table 7 below (Yes for configuration and No for non-configuration).

Table 7 TDRA table usage rules in example 1B

Step 1, a TDRA table used by SPS is set, and the table is characterized in that at least one row is configured with two or more valid SLIVs, as shown in table 8 below.

Table 8 TDRA table used for SPS in example 1B

The way of the specific row:

step 2a, RRC configures the Row index used by the SPS, and the Row index is assumed to be 0.

And step 3a, during scheduling, determining a SLIV index (column index) in the Row index used by the SPS through the Time domain resource assignment of the scheduling signaling DCI, and assuming that the SLIV index is 7.

Step 4a, the UE searches SLIV7 corresponding to Row index =0 in the TDRA table, and determines that the SPS configuration uses S =2; l =2 SLIV.

Column specific approach:

step 2b, RRC configures the column index used by SPS, assuming SLIV1.

And 3b, during scheduling, determining the Row index used by the SPS through the Time domain resource assignment of the scheduling signaling DCI, and assuming that the Row index is 2.

Step 4b, the UE searches SLIV1 corresponding to Row index =2 in the TDRA table, and determines that the SPS configuration uses S =2; l =8 SLIV.

Example 1C: one SPS configuration (comprising only one PDSCH) is activated or retransmitted per DCI

In this embodiment, when the configured SPS is activated or performs scheduling retransmission, the time domain information index indicated by the scheduling signaling DCI is at least one row of pdsch-timedomainnalockationlist-for-multicopdsch tables configured with two or more effective SLIVs.

For example: the base station is configured with 1 or more TDRA tables, wherein all rows of the pdsch-TimeDomainAllocationList only have one effective SLIV; or, the base station configures 1 or more TDRA tables, where at least one row of the pdsch-timedomainnalococcentiylist-for-multicopdsch is configured with two or more effective SLIVs.

Then, when the UE receives the SPS activation or retransmission scheduling signaling (DCI scrambling using CS-RNTI), the UE considers that the pdsch-time domain allocation list _ for multi pdsch is used as the TDRA table of the time domain information index. See table 9 below (Yes for configuration and No for non-configuration).

Table 9 rules for TDRA table usage in example 1C

Step 1, a TDRA table used by SPS is set, and the table is characterized in that at least one row is configured with two or more valid SLIVs, as shown in table 10 below.

Table 10 TDRA table for SPS in example 1C

And step 2, during scheduling, determining the Row index used by the SPS through the Time domain resource assignment of the scheduling signaling DCI, and assuming that the Row index is 0.

And 3, defaulting the first valid value SLIV1 in the Row index used by the SPS.

Step 4, the UE searches for a Row corresponding to the Row index =0 in the TDRA table, and defaults to use the first valid value SLIV1 of the Row as the SPS configuration, that is, it is determined that the SPS configuration uses S =2; l =12 SLIV.

Example 1D: one SPS configuration (comprising only one PDSCH) is activated or retransmitted per DCI

In this embodiment, when the configured SPS is activated or performs scheduling retransmission, at least one row of the common TDRA table pdsch-timedomainnalocorticlationsist _ for multicopdsch table configured with two or more active SLIVs is used as the time domain information index indicated by the scheduling signaling DCI.

Then, when the UE receives the SPS activation or retransmission scheduling signaling (DCI scrambling with CS-RNTI), the UE considers that the pdsch-time domain allocation list _ for multi pdsch is used as the TDRA table for time domain information indexing. See table 11 below (Yes for configuration, no for non-configuration).

Table 11 rules for TDRA table usage in example 1D

Step 1, a TDRA table used by SPS is set, and the table is characterized in that at least one row is configured with two or more valid SLIVs, as shown in table 12 below.

Table 12 TDRA table for SPS use in example 1D

Step 2, generating M effective SLIVs in a certain order from a configured TDRA table, where M may be 8, and sequentially finding out 8 SLIVs with different values in a column-first and row-second manner, that is, (S =2 l = 12), (S =4 l = 8), (S =2 l = 6), (S =4 l = 7), (S =2 l = 4), (S =2 l =14, and (S =0 l = 14).

Step 3, during scheduling, determining SLIV used by the SPS through the Time domain resource assignment of the scheduling signaling DCI, and assuming that the indication is the first value in the SLIV set, namely S =2; l =12.

Step 4, the UE searches a corresponding SLIV set in the TDRA table, and finds a first SLIV value in the SLIV set as SPS configuration, namely, the SPS configuration is determined to use S =2; l =12 SLIV.

Example 2A: one SPS configuration (comprising multiple PDSCHs) is activated or retransmitted per DCI

In this embodiment, when the configured SPS is activated or performs scheduling retransmission, the time domain information index indicated by the scheduling signaling DCI is a TDRA table in which at least one row is configured with two or more effective SLIVs, regardless of whether the base station is configured with a scheduling TDRA table of a single PDSCH.

Then, when the UE receives the SPS activation or retransmission scheduling signaling (DCI scrambling using CS-RNTI), the UE considers that the table of the pdsch-time domain allocation list _ for multi pdsch type is always used as the TDRA table of the time domain information index. The TDRA table may be configured specifically for SPS, or may be shared with dynamic scheduling, and preferably uses a special TDRA table for SPS scheduling. See table 13 below for case specific divisions (Yes for configured and No for unconfigured).

Step 1, a TDRA table used by SPS is set, and the table is characterized in that at least one row is configured with two or more valid SLIVs, as shown in table 14 below.

And step 2, when the DCI uses the CS-RNTI for scrambling, the UE searches the table of the table 14.

And step 3, if the Row index configured by the Time domain resource assignment of the DCI is 0, the UE determines that the SPS configuration uses the SLIV set corresponding to Row index = 0.

Table 14 TDRA table used for SPS in example 2A

Example 3: configuration method of HARQ process ID (process number) for activating or retransmitting one SPS configuration (containing multiple PDSCHs) by each DCI

Step 1, configuring HARQ maximum process number nrofHARQ-process in DCI.

And step 2, configuring HARQ process number Offset value HARQ-ProcID-Offset-r16 of PDSCH in the DCI.

And 3, the UE calculates the HARQ process number of the first PDSCH (corresponding to SLIV 1) according to the HARQ process number deviation value.

And 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 the HARQ Processes does not reach the maximum number of the HARQ Processes nroflHARQ-Processes, the number of the HARQ Processes is overlapped from the PDSCH of the first SLIV again in sequence until the number of the HARQ Processes reaches the maximum number of the HARQ Processes.

For example, assuming that a total SPS scheduling configures 4 PDSCHs corresponding to SLIV1 to SLIV4, respectively, and the HARQ process number (i.e., the first HARQ process number) calculated from the HARQ-ProcID-Offset-r16 is 1, and the maximum number of Processes nrofHARQ-Processes is 8, the HARQ process number configuration is as shown in table 15 below.
