Detailed Description

In the embodiment of the application, the term "and/or" describes the association relation of the association objects, which means that three relations can exist, for example, A and/or B, and can mean that A exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the context-dependent object is an "or" relationship.

The term "plurality" in embodiments of the present application means two or more, and other adjectives are similar.

The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments, but not all embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

LTE systems may support semi-persistent scheduling. For example, the LTE system informs the terminal of information of semi-persistent scheduling through RRC signaling and then informs the terminal when to start semi-persistent scheduling through a PDCCH channel.

In The third generation partnership project (The 3rd Generation Partnership Project,3GPP) evolution standard (Release 16, r 16) protocol version, for semi-persistent scheduling, while multiple SPS configurations are supported, only one SPS can be activated at a time, and when multiple SPS configurations need to be activated, multiple DCI (Downlink Control Information ) commands need to be sent.

In the discussion of R17, the standard decides to support a function that one DCI can schedule a maximum of 8 PDSCH at the same time in high frequency (the number of PDSCH specifically scheduled is decided by the base station). How to perform one DCI to activate multiple SPS configurations based on the time domain resource allocation (Time domain resource assignment, TDRA) of RRC signaling configuration is an important issue to be solved in the industry.

For example, in the 52.6 GHz-71 GHz frequency band, control and data channels of a subcarrier spacing (Subcarrier Spacing, SCS) of 480/960KHz are supported, and one DCI is also supported to schedule a plurality of PDSCH. Wherein, one DCI may schedule 8 PDSCH at the same time at most, or may schedule PDSCH less than 8 PDSCH, which is specifically determined by RRC configuration. In R16, configuration of multiple SPS is supported, but only one SPS can be activated at a time. When multiple SPS configurations need to be activated, multiple commands need to be sent, their activation indicates (where DCI scrambled configured scheduling radio network temporary identity (Configured Scheduling-Radio Network Temporary Identifier, CS-RNTI)) as shown in table 1 below:

Table 1 shows DCI field settings (CS-RNTI scrambling DCI) to activate one SPS configuration, as shown in table 1:

TABLE 1

Where μ is used to represent the minimum SCS configuration between the SCS configuration of the PDCCH providing SPS PDSCH release and the SCS configuration of the uplink control channel (Physical Uplink Control Channel, PUCCH) carrying hybrid automatic repeat request acknowledgement character (Hybrid Automatic Repeat Request-Acknowledge character, HARQ-ACK) information in response to SPS PDSCH release.

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

Table 2 shows the parameter list for RRC configuration SPS (SPS-ConfigIndex-r 16), as shown in Table 2:

TABLE 2

The embodiment of the application provides a channel scheduling method, equipment, a device and a storage medium, wherein each SPS is transmitted corresponding to one PDSCH, a plurality of SPS configurations are activated through DCI, wherein the DCI indicates the number of activated or retransmitted SPS, and the information bits used by the HARQ process number of the DCI are used for indicating a first activated SPS or SPS activation list, so that the flexibility of PDSCH scheduling is realized, and the SPS is more conveniently configured.

The MIMO transmission may be 2D-MIMO, 3D-MIMO, FD-MIMO, or massive-MIMO, or may be diversity transmission, precoding transmission, beamforming transmission, or the like, depending on the form and number of the root antenna combinations.

Fig. 1 is a schematic flow chart of a channel scheduling method according to an embodiment of the present application, where the channel scheduling method may be used for a network device, such as a base station, and as shown in fig. 1, the channel scheduling method may include the following steps:

Step 101, determining a control signaling, wherein the control signaling is used for indicating PDSCH of N SPS, and N is an integer greater than or equal to 1.

Specifically, the control signaling for indicating PDSCH of N SPS may be DCI signaling, or may be other types of control signaling.

If the control signaling is a DCI signaling, the DCI signaling may refer to a control signaling for simultaneously scheduling PDSCH of multiple SPS, that is, one DCI signaling may simultaneously schedule PDSCH of multiple SPS. For example, one DCI signaling may schedule PDSCH of 8 SPS or PDSCH of less than 8 SPS at the same time.

And 102, transmitting the control signaling to the terminal equipment, so that the terminal equipment determines PDSCH of N SPS according to the control signaling.

Specifically, after the network device completes the configuration of the control signaling, the control signaling may be sent to the terminal device, so that after the terminal device receives the control signaling, PDSCH of N SPS may be determined according to the control signaling.

If the control signaling is DCI signaling, the network device may send the DCI signaling to the terminal device after configuring the DCI signaling, so that the terminal device may determine PDSCH of N SPS according to the DCI signaling after receiving the DCI signaling.

For example, the DCI signaling simultaneously schedules PDSCH of 8 SPS or PDSCH of less than 8 SPS, and the terminal device may determine PDSCH of 8 SPS or PDSCH of less than 8 SPS according to the DCI signaling.

The embodiment shows that the control signaling is used for indicating the PDSCH of N SPS by determining the control signaling, N is an integer greater than or equal to 1, and the control signaling is sent to the terminal equipment, so that the terminal equipment determines the PDSCH of N SPS according to the control signaling, one control signaling can schedule the PDSCH of a plurality of SPS at the same time, and the efficiency of channel scheduling is improved.

Optionally, the control signaling includes TDRA identification information for indicating a time domain location where PDSCH of N SPS is located, TDRA identification information is a row index pointing to TDRA table, and each row in TDRA table includes a plurality of start and length information values (START AND LENGTH Indicator Value, SLIV).

In particular, TDRA identification information may point to a row in the TDRA table that may be used to determine the plurality SLIV of SPS configurations to use if the row includes a plurality SLIV. For example, TDRA tables include three rows, each row having a row index of 0,1, 2, and 8 rows SLIV each, SLIV, SLIV2, SLIV.

And, the valid values (i.e., non-invalid values) corresponding to the plurality SLIV of SPS configurations indicate the time-domain positions where PDSCH of N SPS are located.

In addition, TDRA identification information may be located in a time domain resource allocation (Time domain resource assignment) field in DCI signaling.

It should be noted that, in an embodiment of the present application, one or more TDRA tables configured by the network device may be included, and the TDRA table pointed to by the TDRA identification information may be a specific TDRA table in the one or more TDRA tables.

As can be seen from the above embodiment, the network device configuration TDRA is capable of better searching the time domain position where the PDSCH of N SPS is located, that is, TDRA identification information points to one row in the TDRA table, the valid value (that is, the non-valid value) indicates the time domain position where the PDSCH of N SPS is located, and meanwhile, the TDRA table configured by the network device is capable of more conveniently indicating the time domain position where the PDSCH is located, so that the efficiency of determining the time domain position where the PDSCH of N SPS is located is improved.

Optionally, the channel scheduling method further includes:

Determining a first high-level signaling, wherein the first high-level signaling is used for indicating TDRA a table, and each row in the TDRA table comprises a plurality of SLIV;

and sending the first high-layer signaling to the terminal equipment so that the terminal equipment obtains TDRA tables according to the first high-layer signaling.

Specifically, the first higher layer signaling for indicating the TDRA table may be first RRC signaling, or may be a medium access Control-Control Element (MAC-CE), or may be other higher layer signaling.

For example, the first higher layer signaling is first RRC signaling, and the network device may configure TDRA the table to the terminal in advance through the first RRC signaling, so that when the terminal receives control signaling (e.g., DCI signaling) for indicating PDSCH of N SPS, the plurality of SLIV used for SPS configuration may be determined from the TDRA table indicated by the first RRC signaling according to a row index indicated by the control signaling (e.g., DCI signaling).

For another example, TDRA is shown in table 3, which includes three rows with row indices of 0, 1,2, respectively, and 8 rows SLIV, SLIV, SLIV2, SLIV, respectively.

TABLE 3 Table 3

Wherein K0 represents a slot offset value, S represents a value of a start symbol index, L represents a symbol length value, invalid represents an Invalid value, SLIV represents a start and length information value, a subsequent number K (K may be any one digit from 1 to 8) is a slot number, a slot index is determined by K0 and the slot number together, and a slot index calculation method is that n+k0+k-1 starts from a slot number n where DCI is located.

As can be seen from the above embodiments, the TDRA table is sent to the terminal device through the first high-layer signaling, so that the terminal device can obtain TDRA table through the first high-layer signaling, and further determine a plurality of SLIV used by SPS configuration according to the row index indicated by the control signaling, thereby improving accuracy of determining the time domain positions of PDSCH of N SPS.

Optionally, the control signaling further comprises first identification information for indicating a first activated SPS of the N SPS, the first identification information being an SPS index pointing to the SPS configuration parameter set.

Specifically, the first identification information may indicate a first activated SPS of the N SPS. While other SPS of the N SPS may be indirectly determined by the first identification information.

For example, the SPS for the first activated SPS is identified as1, the SPS for the second activated SPS is identified as 2, the SPS for the third activated SPS is identified as 3, and so on.

For another example, the SPS of the first activated SPS is identified as 1, the SPS of the second activated SPS is identified as 3, the SPS of the third activated SPS is identified as 5, and so on.

The SPS configuration parameter set to which the first identification information points may refer to the parameter list of the RRC configuration SPS shown in table 2 above. The SPS index of the SPS configuration parameter set may refer to the SPS configuration index (SPS-ConfigIndex-r 16) in Table 2 above.

It should be noted that, in an embodiment of the present application, one or more SPS configuration parameter sets configured by the network device may be included, and the SPS configuration parameter set pointed to by the first identification information may be a specific SPS configuration parameter set of the one or more SPS configuration parameter sets.

The network device may send the SPS configuration parameter set to the terminal device in advance through high-level signaling, for example, the network device may send the SPS configuration parameter set to the terminal device in advance through first high-level signaling for indicating TDRA a table, that is, the first high-level signaling includes the SPS configuration parameter set. For another example, the network device may send the SPS configuration parameter set to the terminal device in advance via another higher layer signaling than the first higher layer signaling, i.e., the signaling indicating the SPS configuration parameter set is a separate signaling.

The first identification information may be located in a HARQ process number field of DCI signaling, such as a HARQ process number (HARQ process ID) field shown in table 4.

TABLE 4 Table 4

As can be seen from the above embodiments, the first SPS of the N SPS is indicated by the first identification information, so that the terminal device can determine, according to the first identification information and the setting rule, the SPS identification of each SPS of the N SPS, thereby improving the efficiency of SPS configuration.

Optionally, the parameters in the SPS configuration parameter set include a hybrid automatic repeat request (Hybrid Automatic Repeat Request, HARQ) process number offset value, which is used to determine the HARQ process numbers for the N SPS.

Specifically, the SPS configuration parameter set may refer to the parameter list of the RRC configuration SPS shown in table 2 above. The HARQ process number Offset value of the SPS configuration parameter set may refer to the HARQ process number Offset value in table 2 above, i.e., HARQ-ProcID-Offset-r16, inter (0..15).

When determining the HARQ process numbers of the N SPS, the HARQ process number may be determined according to the HARQ process number offset value and the setting rule. Among these, the following two determination methods may be included, but are not limited:

firstly, distributing the HARQ process number to a first activated SPS in a plurality of SPS, and sequentially distributing the HARQ process number corresponding to the previous SPS in the plurality of SPS to the next SPS by adding 1 until each activated SPS in the plurality of SPS is distributed with the HARQ process number;

if the number of the allocated HARQ process numbers is determined to be smaller than the maximum number of the HARQ processes, the last number of the allocated HARQ process numbers is increased by 1 to be allocated to the first activated SPS in the plurality of SPS, the number of the HARQ process numbers corresponding to the previous SPS in the plurality of SPS is increased by 1 to be allocated to the next SPS in sequence, and the number of the allocated HARQ process numbers is updated until the number of the allocated HARQ process numbers after updating is equal to the maximum number of the HARQ process numbers.

For example, assuming a total of 8 HARQ process numbers, 1,2, 3, 4, 5, 6, 7, 8, 4 PDSCH, PDSCH-1, PDSCH-2, PDSCH-3, PDSCH-4, respectively, when 8 HARQ process numbers are allocated, 1, 5 may be allocated to PDSCH-1, 2, 6 may be allocated to PDSCH-2, 3, 7 may be allocated to PDSCH-3, and 4, 8 may be allocated to PDSCH-4.

The second mode is that the maximum process number of HARQ is evenly distributed to each SPS in N SPS, the process number of each SPS is Q, each HARQ process number in a first range is evenly distributed to a first activated SPS in a plurality of SPS, each HARQ process number in a second range corresponding to a previous SPS in the plurality of SPS is evenly distributed to a next SPS in sequence until each activated SPS in the plurality of SPS is evenly distributed with the HARQ process number, wherein Q is a numerical value larger than 1, the first range comprises the HARQ process number to the HARQ process number plus Q-1, and the second range comprises the last process number corresponding to the previous SPS plus 1 to the last process number plus Q.

For example, assuming a total of 8 HARQ process numbers, 1,2, 3,4, 5, 6, 7, 8, 4 PDSCH, PDSCH-1, PDSCH-2, PDSCH-3, PDSCH-4, respectively, when allocating 8 HARQ process numbers, 1,2 may be allocated to PDSCH-1, 3,4 may be allocated to PDSCH-2, 5, 6 may be allocated to PDSCH-3, and 7, 8 may be allocated to PDSCH-4.

As can be seen from the above embodiments, the HARQ process numbers of the N SPS may be determined by the HARQ process number offset value, thereby ensuring that one DCI signaling may schedule PDSCH of multiple SPS at the same time.

Optionally, the control signaling further includes second identification information for indicating all active SPS of the N SPS, the second identification information being an SPS list index pointing to an SPS active list.

In particular, the second identification information may indicate all active SPS of the N SPS.

The SPS activation list to which the second identification information points may refer to one SPS activation list configured by the network device through RRC signaling. The SPS activation list may include SPS identifications of all activated SPS of the N SPS.

For example, 3 SPS identifications are configured in the SPS activation list, which are SPS-id=2, SPS-id=3, and SPS-id=5, respectively.

It should be noted that in the embodiment of the present application, one or more SPS activation lists configured by the network device may be included, and the SPS activation list pointed to by the second identification information may be a specific SPS activation list in the one or more SPS activation lists.

The network device may send the SPS activation list to the terminal device in advance by high-level signaling, for example, the network device may send the SPS activation list to the terminal device in advance by the first high-level signaling for indicating TDRA the table, i.e., the first high-level signaling includes the SPS activation list. For another example, the network device may send the SPS activation list to the terminal device in advance via another higher layer signaling than the first higher layer signaling, i.e., the signaling indicating the SPS activation list is a separate signaling.

The second identification information may be located in a HARQ process number field of the control signaling, such as a HARQ process number (HARQ process ID) field shown in table 5.

TABLE 5

As can be seen from the above embodiments, through all the activated SPS in the N SPS of the second identification information, the terminal device can directly determine the SPS identifier of each activated SPS in the N SPS according to the SPS activation list pointed to by the second identification information, thereby improving the flexibility of SPS configuration.

Optionally, the channel scheduling method further includes:

determining a second high-level signaling, wherein the second high-level signaling is used for indicating an SPS activation list;

And sending the second high-layer signaling to the terminal equipment so that the terminal equipment acquires the SPS activation list according to the second high-layer signaling.

Specifically, the network device may send the SPS activation list to the terminal device through second higher layer signaling. The second higher layer signaling may be the same as or different from the first higher layer signaling used to indicate TDRA the table.

The second higher layer signaling for indicating the SPS activation list may be a second RRC signaling, or may be a MAC-CE, or may be other higher layer signaling.

In addition, the network device may configure a plurality of SPS activation lists, where the SPS activation list may be one of the plurality of SPS activation lists.

For each SPS activation list, a maximum of a first number (i.e., maxNrofSPS-ActivationState) of activation states may be configured, with the parameters of each activation state being configured by SPS configuration activation states (i.e., SPS-ConfigAactivationState), a maximum of PDSCH containing a second number (i.e., maxNrofSPS-Config) of SPS.

As can be seen from the above embodiments, by sending the SPS activation list to the terminal device through the second higher layer signaling, the terminal device may obtain the SPS activation list from the second higher layer signaling, and further determine the SPS identifier of each activated SPS in the N SPS, thereby improving accuracy of SPS configuration.

Optionally, the control signaling includes one or more of RV, NDI, and K1 indications;

wherein RV is all 0, NDI is all 0, and K1 indication comprises:

When activated, K1 is a slot position of an uplink control channel PUCCH calculated from a position of a last scheduled PDSCH among the N SPS PDSCHs;

in data transmission, K1 is a respective PUCCH slot position calculated from each PDSCH of the N SPS PDSCHs.

Wherein K1 is used to characterize the PDSCH-to-HARQ feedback timing indicator.

Specifically, RV may be located in a redundancy version number (Redundancy version) field shown in table 4 or table 5, and its value may be all 0.

NDI may be located in the new data indication (new data indication) field shown in table 4 or table 5, and its value may be all 0.

K1 may be located in a PDSCH-to-HARQ feedback timing indicator (PDSCH-to-harq_ feedback timing indicator) field shown in table 4 or table 5.

Wherein the K1 indication may include, but is not limited to, the following two cases:

In the first case, when a plurality of SPS are activated under the multi-PDSCH scheduling, K1 is the time slot position of an uplink control channel PUCCH calculated from the position of the last scheduled PDSCH in the PDSCH of N SPS;

In case two, K1 is a respective PUCCH slot position calculated from each PDSCH of the N SPS PDSCH data transmissions.

According to the embodiment, the RV, the NDI and the K1 are indicated through the control signaling, so that the terminal equipment can acquire the RV, the NDI and the K1 indicated by the network equipment from the control signaling, and the accuracy of channel scheduling is improved.

Fig. 2 is a second flow chart of a channel scheduling method according to an embodiment of the present application, where the channel scheduling method may be used for a terminal device, and as shown in fig. 2, the channel scheduling method may include the following steps:

step 201, receiving a control signaling sent by a network device, where the control signaling is used to indicate PDSCH of N SPS, and N is an integer greater than or equal to 1.

Specifically, the control signaling for PDSCH indicating N SPS may be DCI signaling, or may be other types of control signaling.

Step 202, determining PDSCH of N SPS according to the control signaling.

Specifically, after receiving the control signaling, the terminal device may determine PDSCH of N SPS according to the control signaling.

If the control signaling is DCI signaling, the terminal device may determine PDSCH of N SPS according to the DCI signaling after receiving the DCI signaling.

As can be seen from the above embodiments, by receiving the control signaling sent by the network device, the control signaling is used to indicate PDSCH of N SPS, where N is an integer greater than or equal to 1, so that one control signaling can schedule PDSCH of multiple SPS at the same time, and efficiency of channel scheduling is improved.

Optionally, the control signaling includes TDRA identification information for indicating a time domain location where PDSCH of N SPS is located, TDRA identification information is a row index pointing to TDRA table, and each row in TDRA table includes a plurality of SLIV.

In particular, TDRA identification information may point to a row in the TDRA table that may be used to determine the plurality SLIV of SPS configurations to use if the row includes a plurality SLIV.

For example, TDRA tables include three rows, each row having a row index of 0, 1,2, and 8 rows SLIV each, SLIV, SLIV2, SLIV.

In addition, TDRA identification information may be located in a time domain resource allocation (Time domain resource assignment) field in the control signaling.

As can be seen from the above embodiments, by using TDRA identification information, the time domain position where the PDSCH of N SPS is located can be better found, that is, TDRA identification information points to one row in the TDRA table, and the valid value (i.e., the non-valid value) indicates the time domain position where the PDSCH of N SPS is located, so that the efficiency of determining the time domain position where the PDSCH of N SPS is located is improved.

Optionally, the channel scheduling method further includes:

receiving a first high-layer signaling sent by the network equipment, wherein the first high-layer signaling is used for indicating TDRA tables;

The TDRA table is obtained from the first high-level signaling.

Specifically, the first higher layer signaling used for indicating TDRA the table may be first RRC signaling, may also be MAC-CE, or may also be other higher layer signaling.

For example, the first higher layer signaling is a first RRC signaling, and when the terminal receives control signaling (e.g., DCI signaling) for indicating PDSCH of N SPS, the plurality of SLIV used for SPS configuration may be determined from the TDRA table indicated by the first RRC signaling according to a row index indicated by the DCI signaling.

For example, TDRA is shown in table 6, which includes three rows with row indices of 0,1, 2, respectively, and 8 rows SLIV, SLIV, SLIV2, SLIV, respectively.

TABLE 6

As can be seen from the above embodiments, the first higher layer signaling obtains TDRA the table, and further determines a plurality of SLIV used for SPS configuration according to the row index indicated by the control signaling, thereby improving accuracy of determining the time domain positions of PDSCH of N SPS.

Optionally, the control signaling further comprises first identification information for indicating a first activated SPS of the N SPS, the first identification information being an SPS index pointing to the SPS configuration parameter set. Correspondingly, in executing step 202, the following implementation process may specifically include, but is not limited to:

a. Determining SLIV values corresponding to the SLIV indexes pointed by TDRA identification information according to TDRA tables, wherein the SLIV values comprise valid values or invalid values;

b. Determining N activated SPS according to the number of the effective values in each SLIV index;

c. determining an SPS identification of each activated SPS in the N SPS according to the first identification information;

d. Determining the corresponding relation between the SPS identification of each activated SPS in the N SPS and the effective value in each SLIV index according to a first setting rule;

e. And determining the HARQ process number of each activated SPS in the N SPSs according to a second set rule.

Specifically, when determining the active N SPS, as shown in table 6, SLIV1, SLIV2, & gt, SLIV are all valid values when the row index is 0, SLIV, SLIV2, and SLIV4 are invalid values when the row index is 1, the rest are valid values, SLIV2, SLIV3, and SLIV are invalid values when the row index is 2, and the rest are valid values. If the first identification information is 0, the number of the effective values is 8, which indicates that the control signaling indicates that 8 SPS are activated, and if the first identification information is 1 or 2, the number of the effective values is 5, which indicates that the control signaling indicates that 5 SPS are activated.

In determining the SPS identification of each of the N SPS's active SPS based on the first identification information, the first identification information may indicate a first one of the N SPS's active SPS, and other ones of the N SPS's may be indirectly determined by the first identification information. For example, the SPS for the first activated SPS is identified as 1, the SPS for the second activated SPS is identified as 2, the SPS for the third activated SPS is identified as 3, and so on. For another example, the SPS of the first activated SPS is identified as 1, the SPS of the second activated SPS is identified as 3, the SPS of the third activated SPS is identified as 5, and so on.

The first identification information may be located in a HARQ process number field of the control signaling, such as the HARQ process number (HARQ process ID) field shown in table 4 above.

The first setting rule and the second setting rule may be defined by a communication protocol, or may be configured to the terminal device in advance by the network device through signaling.

In addition, the SPS configuration parameter set to which the first identification information points may refer to the parameter list of the RRC configuration SPS shown in table 2 above. The SPS index of the SPS configuration parameter set may refer to the SPS configuration index (SPS-ConfigIndex-r 16) in Table 2 above.

As can be seen from the above embodiments, the SPS identifier of each activated SPS of the N SPS, the correspondence between the SPS identifier of each activated SPS and the effective value in the index of each SLIV, and the HARQ process number of each activated SPS of the N SPS may be determined by the first identifier information, the first setting rule, and the second setting rule, so that it is ensured that one control signaling may schedule PDSCH of multiple SPS at the same time, and the reliability of channel scheduling is improved.

Optionally, the parameters in the SPS configuration parameter set include HARQ process number offset values, where the HARQ process number offset values are used to determine HARQ process numbers for the N SPS;

(1) The first setting rule may include:

the SPS identifier of the first activated SPS of the N SPS corresponds to the first valid value in each SLIV index;

The SPS identifier of the Mth activated SPS in the N SPS corresponds to the Mth effective value in each SLIV index, M is an integer which is more than 1 and less than or equal to N, and the SPS identifier of the Mth activated SPS is the first identification information plus a set value;

If the time slot where the mth valid value is located is the uplink time slot, the mth activated SPS cannot be used for scheduling data.

Specifically, the set value may be M-1, such as the first identification information is 1, the SPS of the 2 nd activated SPS is 2, the SPS of the 3 rd activated SPS is 3, and so on, or other values, such as the first identification information is 1, the SPS of the 2 nd activated SPS is 3, the SPS of the 3 rd activated SPS is 5, and so on.

When the correspondence is determined according to the first setting rule, as shown in fig. 3:

The method 1 comprises the steps that if SLIV index value ranges are 1-4 and SLIV2 is invalid, the corresponding SPS-ID 2 is not activated, and SPS-ID 1/3/4 is activated.

Method 2. Assuming SLIV index value range is 1-4, SLIV2 is inactive, SPS-ID2 is active but time domain position corresponds to SLIV, SPS-ID3 is active but time domain position corresponds to SLIV, SPS-ID4 is inactive.

When the correspondence is determined according to the first setting rule, for the case of the uplink time slot, as shown in fig. 4:

TDRA = { row index 0:sliv-1 (s=2, l=10), SLIV-2 ((s=2, l=10), SLIV-3 (s=2, l=10), SLIV-4 (s=2, l=10) }.

Assuming that SLIV index value ranges from 1 to 4 and that SLIV-2 (i.e., SLIV indicated by numeral 5 in FIG. 4) is an uplink slot, SPS-ID=2 activates but does not schedule data.

(2) The second setting rule includes the following one or two modes:

For example, assuming a total of 8 HARQ process numbers, 1, 2,3, 4, 5, 6, 7, 8, 4 PDSCH, PDSCH-1, PDSCH-2, PDSCH-3, PDSCH-4, respectively, when allocating 8 HARQ process numbers, 1, 5 may be allocated to PDSCH-1, 2, 6 may be allocated to PDSCH-2, 3, 7 may be allocated to PDSCH-3, and 4, 8 may be allocated to PDSCH-4, as in the following scheme 1 in Table 7.

TABLE 7

For example, assuming a total of 8 HARQ process numbers, 1, 2,3, 4, 5, 6, 7, 8, 4 PDSCH, PDSCH-1, PDSCH-2, PDSCH-3, PDSCH-4, respectively, when allocating 8 HARQ process numbers, 1, 2 may be allocated to PDSCH-1, 3, 4 may be allocated to PDSCH-2, 5, 6 may be allocated to PDSCH-3, and 7, 8 may be allocated to PDSCH-4 as in the above-described method 2 in Table 7.

The above embodiment can be seen that the HARQ process numbers of the N SPS are determined by the HARQ process number offset value, so that one control signaling can schedule PDSCH of multiple SPS at the same time, and flexibility of channel scheduling is improved.

Optionally, the control signaling further includes second identification information for indicating all active SPS in the N SPS, where the second identification information is an SPS list index pointing to an SPS active list, and in response thereto, when executing step 202, the following implementation process may specifically include, but is not limited to:

b. determining each SPS identifier pointed by the second identification information according to the SPS activation list;

c. Determining N SPS to be activated according to the total number of the SPS identifiers;

d. determining an SPS identifier of each activated SPS in the N SPS according to each SPS identifier;

e. determining the corresponding relation between the SPS identification of each activated SPS in the N SPS and the effective value in each SLIV index according to a third setting rule;

f. And determining the HARQ process number of each activated SPS in the N SPSs according to a fourth set rule.

Specifically, as shown in table 6, SLIV1, SLIV2, & gt, SLIV are all valid values when the row index is 0, SLIV1, SLIV2, SLIV are invalid values when the row index is 1, and the rest are valid values, SLIV2, SLIV3, SLIV are invalid values when the row index is 2, and the rest are valid values.

The second identification information may indicate all active SPS of the N SPS.

The SPS activation list to which the second identification information points may refer to one SPS activation list configured by the network device through higher layer signaling. The SPS activation list may include SPS identifications of all activated SPS of the N SPS.

The second identification information may be located in a HARQ process number field of the control signaling, such as the HARQ process number (HARQ process ID) field shown in table 5 above.

The third setting rule and the fourth setting rule may be defined by a communication protocol, or may be configured by the network device to the terminal device in advance through signaling.

Wherein (1) the third setting rule includes:

when the corresponding relation is determined according to the third setting rule, as shown in fig. 5, assuming that SLIV index value ranges are 1-5, and that sliv2 is invalid, the SPS activation list pointed by the second identification information is configured with SPS-id=2/3/5, SLIV corresponds to SPS-ID2, SLIV3 corresponds to SPS-ID3, SLIV4 corresponds to SPS-ID5.

When the correspondence is determined according to the third setting rule, for the case of the uplink time slot, as shown in fig. 4, the above is shown:

(2) The fourth setting rule includes the following one or two modes:

For example, assuming a total of 8 HARQ process numbers, 1, 2,3, 4, 5, 6, 7, 8, 4 PDSCH, PDSCH-1, PDSCH-2, PDSCH-3, PDSCH-4, respectively, when allocating 8 HARQ process numbers, 1, 5 may be allocated to PDSCH-1, 2, 6 may be allocated to PDSCH-2, 3, 7 may be allocated to PDSCH-3, and 4, 8 may be allocated to PDSCH-4, as in the above-described scheme 1 in Table 7.

The second mode is that the maximum process number of HARQ is evenly distributed to each SPS in N SPS, the process number of each SPS is Q, each HARQ process number in a third range is evenly distributed to the first activated SPS in the plurality of SPS, each HARQ process number in a fourth range corresponding to the previous SPS in the plurality of SPS is evenly distributed to the next SPS in sequence until each activated SPS in the plurality of SPS is evenly distributed with the HARQ process number, wherein Q is a numerical value larger than 1, the third range comprises the HARQ process number to the HARQ process number plus Q-1, and the fourth range comprises the last process number corresponding to the previous SPS plus 1 to the last process number plus Q.

As can be seen from the above embodiments, the SPS identifier of each activated SPS of the N SPS, the correspondence between the SPS identifier of each activated SPS and the effective value in the index of each SLIV, and the HARQ process number of each activated SPS of the N SPS may be determined by the second identifier information, the third setting rule, and the fourth setting rule, so that it is ensured that one control signaling may schedule PDSCH of multiple SPS at the same time, and the reliability of channel scheduling is improved.

Optionally, the channel scheduling method further includes:

Receiving a second high-layer signaling sent by the network equipment, wherein the second high-layer signaling is used for indicating an SPS activation list;

and acquiring an SPS activation list according to the second high-level signaling.

Specifically, the terminal device receives the second higher layer signaling sent by the network device, and may acquire the SPS activation list according to the second higher layer signaling. The second higher layer signaling may be the same as or different from the first higher layer signaling used to indicate TDRA the table.

As can be seen from the above embodiments, the SPS activation list may be obtained from the second higher layer signaling, so as to determine the SPS identifier of each activated SPS in the N SPS, thereby improving the accuracy of SPS configuration.

Optionally, the control signaling includes control signaling including one or more of RV, NDI, and K1 indications;

wherein RV is all 0, NDI is all 0, and K1 indication comprises:

when activated, K1 is a slot position of the PUCCH calculated from a position of a last scheduled PDSCH among the PDSCH of the N SPS;

Wherein it is shown in fig. 6. The K1 indication may include, but is not limited to, the following two cases:

In the first case, when a plurality of SPS are activated under the multi-PDSCH scheduling, K1 is the time slot position of the PUCCH calculated from the position of the last scheduled PDSCH in the PDSCH of N SPS;

As can be seen from the above embodiments, RV, NDI and K1 indicated by the network device may be obtained through control signaling, thereby improving accuracy of channel scheduling.

The implementation of the above-described channel scheduling method will be illustrated by way of two examples.

Example one:

the DCI signaling includes TDRA identification information and first identification information.

Wherein TDRA identification information is a row index pointing to TDRA table, each row in TDRA table includes a plurality of SLIV, and first identification information is used to indicate a first activated SPS of the N SPS and is an SPS index pointing to SPS configuration parameter set.

The specific implementation process comprises the following steps:

(1-1) the base station sets a TDRA table of SPS configurations, wherein TDRA table has a plurality of SLIV values per row.

(1-2) When DCI is scrambled using CS-RNTI, TDRA table of SPS configuration is used.

(1-3) The base station determining a plurality of SLIV for use in SPS configuration by indicating a row index through TDRA of DCI.

(1-4) The terminal device reading the DCI and determining the number of SPS activated and the corresponding SLIV value.

(1-5) The base station indicating the first activated SPS-ID by the first identification information of the DCI, corresponding to the valid value of the first SLIV. The SPS-IDs of other scheduled PDSCH are correspondingly increased by 1, which in turn corresponds to other SLIV valid values.

(1-6) The terminal device determining the plurality of SPS-IDs and associated configuration parameters to activate by reading the DCI.

(1-7) If there is an invalid (invalid) case in all SLIV of the row indexes indicated in step (1-3), then:

Method 1, SPS-ID corresponding to invalid SLIV is not activated, SPS-ID and SLIV correspond in sequence.

Specifically, method 1 as shown in fig. 3:

TDRA = { row index 0:sliv-1 (s=2, l=10), SLIV-2 (invalid), SLIV-3 (s=2, l=10), SLIV-4 (s=2, l=10) }. Assuming SLIV that the index value range is 1-4 and SLIV2 is invalid, the corresponding SPS-ID 2 is not activated and SPS-ID 1/3/4 is activated.

Method 2, invalidate SLIV corresponding SPS-ID activation, corresponding SLIV is delayed back to a valid SLIV value.

Specifically, method 2 as shown in fig. 3:

Assuming SLIV index value ranges are 1-4 and SLIV2 is inactive, SPS-ID 2 is active but the time domain position corresponds to SLIV3, SPS-ID3 is active but the time domain position corresponds to SLIV and SPS-ID4 is inactive.

(1-8) If there are uplink slots in all SLIV of the Row index (Row index) indicated in step (1-3), the SPS-ID corresponding to the uplink slot is active at this time, but the scheduling is inactive at this time.

Specifically, as shown in fig. 4:

Wherein TDRA = { row index 0:sliv-1 (s=2, l=10), SLIV-2 ((s=2, l=10), SLIV-3 (s=2, l=10), SLIV-4 (s=2, l=10) }.

(1-9) HARQ process allocation.

The first mode is that the HARQ process number is allocated to the first activated SPS in a plurality of SPS, and the HARQ process number corresponding to the former SPS in the plurality of SPS is sequentially added with 1 to be allocated to the latter SPS until each activated SPS in the plurality of SPS is allocated with the HARQ process number;

(1-10) When activated, the K1 value is to calculate the slot position of the PUCCH from the position of the last PDSCH scheduled, and when data is transmitted, the K1 value calculates the respective PUCCH slot position for each PDSCH, as shown in fig. 6.

Example two:

The DCI signaling includes TDRA identification information and second identification information.

Wherein TDRA identification information is a row index pointing to TDRA table, each row in TDRA table includes a plurality of SLIV, and the second identification information is used to indicate all active SPS in the N SPS and is an SPS list index pointing to SPS active list.

The second identification information may be located in a HARQ process number field of DCI signaling, such as a HARQ process number (HARQ process ID) field shown in table 4.

The specific implementation process comprises the following steps:

(2-1) the base station sets a TDRA table of SPS configurations, wherein TDRA table has a plurality of SLIV values per row.

(2-2) When DCI is scrambled using CS-RNTI, TDRA table of SPS configuration is used.

(2-3) The base station determining a plurality of SLIV for use in SPS configuration by indicating a row index through TDRA of DCI.

(2-4) The terminal device reading the DCI and determining the SLIV value corresponding to the activated SPS.

(2-5) The base station configuring the SPS activation list through RRC.

A maximum of maxNrofSPS-ActivationState active states may be configured in the SPS configuration active state list SPS-ConfigActivationStateList, with parameters for each active state configured by SPS-ConfigAactivationState, including PDSCH of up to maxNrofSPS-Config SPS. The description is as follows:

SPS-ConfigActivationStateList-r16::＝SEQUENCE(SIZE(1..maxNrofSPS-ActivationState))OF SPS-ConfigActivationState-r16

SPS-ConfigAactivationState-r16::=SEQUENCE(SIZE(1..maxNrofSPS-Config-r16))OF SPS-ConfigIndex-r16

(2-6) the base station indicating an SPS list index of the activated SPS activation list through the second identification information of the DCI.

(2-7) The terminal device determining an SPS list index and associated configuration parameters of the activated SPS activation list by reading the DCI.

(2-8) If there is an invalid in all SLIV of the row indexes indicated in step (2-3), then:

an invalid (invalid) SLIV does not correspond to an SPS-ID, and the SPS-ID indicated by RRC and SLIV valid values correspond in sequence.

Specifically, as shown in fig. 5, assuming that SLIV index value ranges are 1-5, SLIV2 is invalid, and SPS-ID=2/3/5 is configured in SPS LIST ID, SPS-ID2 is corresponding to SLIV1, SLIV3 calls SPS-ID3, SLIV4 corresponds to SPS-ID5.

(2-9) As in example one, if there are uplink slots in all SLIV of the Row index (Row index) indicated in step (2-3), then the SPS-ID corresponding to the uplink slot is active this time, but the scheduling is inactive this time.

(2-10) HARQ process allocation the same as example one, and will not be described in detail here.

(2-11) In the same example as one, the K1 value is to calculate the slot position of the PUCCH from the position of the last PDSCH scheduled at the time of activation, and the K1 value is to calculate the respective PUCCH slot position for each PDSCH at the time of data transmission.
