Detailed Description

In the embodiment of the present application, the term "and/or" describes an association relationship of associated objects, and indicates that three relationships may exist, for example, a and/or B, and may indicate: a exists alone, A and B exist simultaneously, and B exists alone. 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.

The LTE system may support semi-persistent scheduling. Such as: 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.

However, the information of the semi-persistent scheduling is notified to the terminal through the RRC signaling, which is inefficient and cannot meet the demand of the development of the communication technology.

In The protocol version of The 3rd Generation Partnership project (3 gpp) evolution standard (Release 16, R16), for semi-persistent scheduling, although configuration of a plurality of SPS is supported, only one SPS can be activated at a time, and when a plurality of SPS configurations need to be activated, a plurality of DCI (Downlink Control Information) commands need to be transmitted.

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). How to activate multiple SPS configurations by using a DCI based on Time Domain Resource Allocation (TDRA) configured by RRC signaling is an important issue to be solved in the industry.

Such as: in the 52.6 GHz-71 GHz frequency band, control and data channels of 480/960KHz Subcarrier Spacing (SCS) are supported, and simultaneously one DCI is also supported) to schedule a plurality of PDSCHs. One DCI may schedule at most 8 PDSCHs simultaneously, or schedule fewer than 8 PDSCHs, which is specifically determined by RRC configuration. In R16, configuration of multiple SPSs is supported, but only one SPS can be activated at a time. When a plurality of SPS configurations need to be activated, a plurality of commands need to be sent; the activation indication is shown in the following table 1 (where DCI scrambled is Configured Scheduling-Radio Network Temporary Identifier (CS-RNTI)):

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

TABLE 1

/>

Wherein μ is used to represent a minimum SCS configuration between an SCS configuration of a PDCCH providing SPS PDSCH release and an SCS configuration of an Uplink Control Channel (PUCCH) carrying Hybrid Automatic Repeat Request acknowledgement 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 (SPS-ConfigIndex-r 16) of the RRC-configured SPS, 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 corresponds to one PDSCH for transmission, a plurality of SPS configurations are activated through DCI, the DCI indicates the number of activated or retransmitted SPS, and 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 root antenna combinations.

Fig. 1 is a schematic flowchart of a channel scheduling method provided in an embodiment of the present application, where the channel scheduling method may be used in a network device, for example: a base station; as shown in fig. 1, the channel scheduling method may include the following steps:

step 101, determining a control signaling, 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 indicating the PDSCH of the N SPS may be DCI signaling or other types of control signaling.

If the control signaling is DCI signaling, the DCI signaling may refer to control signaling for scheduling PDSCH of multiple SPS simultaneously, that is, one DCI signaling may schedule PDSCH of multiple SPS simultaneously. Such as: one DCI signaling may simultaneously schedule PDSCH of 8 SPS or less than 8 SPS.

And step 102, sending the control signaling to the terminal equipment so that the terminal equipment determines the PDSCHs of the N SPS according to the control signaling.

Specifically, after the network device completes 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, the N SPS PDSCHs 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 completing the DCI signaling, so that the terminal device may determine the N SPS PDSCHs according to the DCI signaling after receiving the DCI signaling.

Such as: the DCI signaling simultaneously schedules 8 SPS PDSCH or less than 8 SPS PDSCH, and the terminal device may determine 8 SPS PDSCH or less than 8 SPS PDSCH according to the DCI signaling.

As can be seen from the above embodiments, by determining a control signaling, the control signaling is used to indicate PDSCH of N SPS, where N is an integer greater than or equal to 1; and sending the control signaling to the terminal equipment so that the terminal equipment determines the PDSCHs of the N SPS according to the control signaling, thereby realizing that one control signaling can simultaneously schedule the PDSCHs of the plurality of SPS and improving the efficiency of channel scheduling.

Optionally, the control signaling includes TDRA identification information for indicating time domain positions of the PDSCH of the N SPS, where the TDRA identification information is a row index pointing to a TDRA table, and each row in the TDRA table includes a plurality of Start and Length Indicator Values (SLIVs).

Specifically, the TDRA identification information may point to a row in the TDRA table, which may be used to determine a plurality of SLIVs used by the SPS configuration if the row includes a plurality of SLIVs. Such as: the TDRA table includes three rows, with row indices of 0, 1, and 2, respectively; each row has 8 SLIVs, SLIV1, SLIV2, …, and SLIV8.

And, valid values (i.e. non-invalid values) corresponding to a plurality of SLIVs used by the SPS configuration indicate time domain positions where the PDSCH of the N SPS is located.

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

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

As can be seen from the foregoing embodiments, the network device configures the TDRA identifier information, so that the time domain positions of the N SPS PDSCHs can be better found, that is, the TDRA identifier information points to a row in the TDRA table, and an effective value (i.e., a non-invalid value) indicates the time domain positions of the N SPS PDSCHs; meanwhile, the TDRA table configured by the network equipment can more conveniently indicate the time domain position of the PDSCH, so that the efficiency of determining the time domain positions of the PDSCHs of the N SPS 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 a TDRA table, and each line in the TDRA table comprises a plurality of SLIVs;

and sending the first high-level signaling to the terminal equipment so that the terminal equipment can acquire the TDRA table according to the first high-level signaling.

Specifically, the first higher layer signaling for indicating the TDRA table may be the first RRC signaling, may also be a Medium Access Control-Control Element (MAC-CE), and may also be other higher layer signaling.

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

For another example: the TDRA table is shown in table 3, and includes three rows, with row indices of 0, 1, and 2; each row has 8 SLIVs, SLIV1, SLIV2, …, and SLIV8.

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 invalidity, SLIV represents a start and length information value, a subsequent number K (K may be any one number from 1 to 8) is a slot number, the slot index is determined by K0 and the slot number together, and the slot index calculation method is that n + K0+ K-1 starts from the slot number n where the 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 the TDRA table through the first high layer signaling, and further determine a plurality of SLIVs used for SPS configuration according to the row index indicated by the control signaling, thereby improving the accuracy of determining the time domain positions of the PDSCHs of the N SPS.

Optionally, the control signaling further includes 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.

In particular, the first identification information may indicate a first activated SPS of the N SPS. While other SPS's of the N SPS may be determined indirectly through the first identification information.

Such as: the SPS identifier of the first activated SPS is 1, the SPS identifier of the second activated SPS is 2, the SPS identifier of the third activated SPS is 3, and so on.

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

The SPS configuration parameter set pointed to by the first identification information may refer to the parameter list of the RRC-configured 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 the 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 higher layer signaling, such as: the network device may send the SPS configuration parameter set to the terminal device in advance through a first higher layer signaling for indicating the TDRA table, that is, the first higher layer signaling includes the SPS configuration parameter set. Another example is as follows: the network device may send the SPS configuration parameter set to the terminal device in advance through another higher layer signaling different from the first higher layer signaling, i.e., the signaling for 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

/>

As can be seen from the above embodiments, the first identifier information indicates the first activated SPS among the N SPS, so that the terminal device may determine the SPS identifier of each activated SPS among the N SPS according to the first identifier information and the setting rule, thereby improving the efficiency of SPS configuration.

Optionally, the parameters in the SPS configuration parameter set include Hybrid Automatic Repeat Request (HARQ) process number offset values, and the HARQ process number offset values are used to determine HARQ process numbers of the N SPS.

Specifically, the SPS configuration parameter set may refer to a parameter list of the RRC-configured 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, INTEREGER (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 a setting rule. The following two determination methods may be included, but not limited to:

the first method is as follows: allocating the HARQ process number to the first activated SPS in the plurality of SPS, and sequentially adding 1 to the HARQ process number corresponding to the previous SPS in the plurality of SPS to allocate to the next SPS until each activated SPS in the plurality of SPS is allocated with the HARQ process number;

and if the number of the distributed HARQ process numbers is smaller than the HARQ maximum process number, the distributed last HARQ process number plus 1 is distributed to the first activated SPS in the plurality of SPS, the HARQ process number corresponding to the previous SPS in the plurality of SPS is sequentially distributed to the next SPS plus 1, and the distributed HARQ process number is updated until the updated distributed HARQ process number is equal to the HARQ maximum process number.

Such as: assuming a total of 8 HARQ process numbers, 1, 2, 3, 4, 5, 6, 7, 8, respectively; 4 PDSCHs, namely PDSCH-1, PDSCH-2, PDSCH-3 and PDSCH-4; 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 method comprises the following steps: averagely distributing the HARQ maximum process number to each SPS in the N SPS, wherein the process number of each SPS is Q, distributing each HARQ process number in a first range to a first activated SPS in the plurality of SPS, and sequentially distributing each HARQ process number in a second range corresponding to a previous SPS in the plurality of SPS to a next SPS until each activated SPS in the plurality of SPS is distributed with the HARQ process number; wherein Q is a value greater than 1, the first range includes HARQ process number to HARQ process number plus Q-1, and the second range includes last process number corresponding to previous SPS plus 1 to plus Q.

Such as: assuming a total of 8 HARQ process numbers, 1, 2, 3, 4, 5, 6, 7, 8, respectively; 4 PDSCHs, namely PDSCH-1, PDSCH-2, PDSCH-3 and PDSCH-4; when 8 HARQ process numbers are allocated, 1, 2, 3, 4, 5, 6, and 7, 8 may be allocated to PDSCH-1, PDSCH-2, PDSCH-3, and PDSCH-4, respectively.

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

Optionally, the control signaling further includes second identification information for indicating all activated SPS of the N SPS, and the second identification information is an SPS list index pointing to the SPS activation list.

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

The SPS activation list pointed to by the second identification information may refer to one SPS activation list configured by the network device through RRC signaling. SPS identities for all activated SPS of the N SPS may be included in the SPS activation list.

Such as: 3 SPS identities 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 forward the SPS activation list to the terminal device through higher layer signaling, such as: the network device may send the SPS activation list to the terminal device in advance through the first higher layer signaling for indicating the TDRA table, that is, the SPS activation list is included in the first higher layer signaling. For another example: the network device may send the SPS activation list to the terminal device in advance through another higher layer signaling different from the first higher layer signaling, i.e., the signaling for 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, by using the second identification information, all the activated SPS in the N SPS, the terminal device may determine the SPS identifier of each activated SPS in the N SPS directly according to the SPS activation list pointed by the second identification information, thereby improving the flexibility of SPS configuration.

Optionally, the channel scheduling method further includes:

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

and sending the second high-level signaling to the terminal equipment so that the terminal equipment acquires the SPS activation list according to the second high-level 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 for indicating the TDRA table.

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

Additionally, the network device may configure multiple SPS activation lists, where an SPS activation list may be one of the multiple SPS activation lists.

For each SPS activation list: up to a first number (i.e., maxNrofSPS-activation state) of active states may be configured, with the parameters of each active state being configured by the SPS configuration active state (i.e., SPS-configaactive state) and up to a second number (i.e., maxNrofSPS-Config) of PDSCHs of the SPS.

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

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

wherein RV is all 0; NDI is all 0; the indication of K1 includes:

when the method is activated, K1 is the time slot position of an uplink control channel PUCCH calculated from the position of the last scheduled PDSCH in PDSCHs of N SPS;

at the time of data transmission, K1 is to calculate the respective PUCCH slot position from each of the N SPS PDSCH.

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

Specifically, the 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's.

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

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:

the first situation is as follows: when a plurality of SPS are activated under the scheduling of multiple PDSCHs, K1 is the time slot position of an uplink control channel PUCCH calculated from the position of the last scheduled PDSCH in the PDSCHs of the N SPS;

case two: at the time of PDSCH data transmission of N SPS, K1 is to calculate the respective PUCCH slot position from each of the N SPS PDSCH.

It can be seen from the above embodiments that, by indicating RV, NDI, and K1 through the control signaling, the terminal device can obtain RV, NDI, and K1 indicated by the network device from the control signaling, thereby improving the accuracy of channel scheduling.

Fig. 2 is a second flowchart of a channel scheduling method provided in the embodiment of the present application, where the channel scheduling method may be used for a terminal device; as shown in fig. 2, the channel scheduling method may include the steps of:

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.

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

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

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

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

It can be seen from the foregoing embodiments that, by receiving a control signaling sent by a 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 simultaneously schedule PDSCH of multiple SPS, thereby improving efficiency of channel scheduling.

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

Specifically, the TDRA identification information may point to a row in the TDRA table, which may be used to determine a plurality of SLIVs used by the SPS configuration if the row includes a plurality of SLIVs.

Such as: the TDRA table includes three rows, with row indices of 0, 1, and 2, respectively; each row has 8 SLIVs, SLIV1, SLIV2, …, and SLIV8.

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

It should be noted that in the embodiment of the present application, one or more TDRA tables configured by the network device may be included, and the TDRA table pointed 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 embodiments, the time domain positions of the N SPS PDSCHs can be better found through the TDRA identifier information, that is, the TDRA identifier information points to one row in the TDRA table, and the effective value (i.e., the non-invalid value) indicates the time domain positions of the N SPS PDSCHs, thereby improving the efficiency of determining the time domain positions of the N SPS PDSCHs.

Optionally, the channel scheduling method further includes:

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

and acquiring the TDRA table according to the first high-layer signaling.

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

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

Such as: the TDRA table is shown in table 6, and includes three rows, with row indices of 0, 1, and 2; each row has 8 SLIVs, SLIV1, SLIV2, …, and SLIV8.

TABLE 6

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

As can be seen from the foregoing embodiments, the TDRA table is obtained through the first high layer signaling, and then the multiple SLIVs used for SPS configuration are determined according to the row index indicated by the control signaling, so that the accuracy of determining the time domain positions of the PDSCHs of the N SPS is improved.

Optionally, the control signaling further includes first identification information for indicating a first activated SPS of the N SPS, and the first identification information is an SPS index pointing to the SPS configuration parameter set. Correspondingly, when step 202 is executed, the following implementation processes may be specifically included, but are not limited to:

a. determining SLIV values corresponding to all SLIV indexes pointed by the TDRA identification information according to the TDRA table, wherein the SLIV values comprise effective values or invalid values;

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

c. determining an SPS identifier for each activated SPS of the N SPS from 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 set rule;

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

Specifically, when N activated SPS are determined, as shown in table 6, and the row index is 0, SLIV1, SLIV2, …, and SLIV8 are all valid values; when the row index is 1, SLIV2 and SLIV4 are invalid values, and the rest are valid values; when the row index is 2, SLIV3, and SLIV4 are invalid values, and the remaining 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 to activate 8 SPS; if the first identification information is 1 or 2, the number of valid values is 5, which indicates that the control signaling indicates to activate 5 SPS.

In determining the SPS identity of each of the N SPS's activated SPS from the first identification information, the first identification information may indicate a first one of the N SPS's activated SPS, while other ones of the N SPS's may be indirectly determined from the first identification information. Such as: the SPS identifier of the first activated SPS is 1, the SPS identifier of the second activated SPS is 2, the SPS identifier of the third activated SPS is 3, and so on. For another example: the SPS identifier of the first activated SPS is 1, the SPS identifier of the second activated SPS is 3, the SPS identifier of the third activated SPS is 5, and so on.

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

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

In addition, the SPS configuration parameter set pointed to by the first identification information may refer to the parameter list of the RRC-configured 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 the 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 in the one or more SPS configuration parameter sets.

It can be seen from the above embodiments that the SPS identifier of each activated SPS in the N SPS, the corresponding relationship between the SPS identifier of each activated SPS and the effective value in each SLIV index, and the HARQ process number of each activated SPS in the N SPS can be respectively determined by the first identifier information, the first setting rule, and the second setting rule, thereby ensuring that one control signaling can simultaneously schedule the PDSCHs of multiple SPS, and improving the reliability of channel scheduling.

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 of the N SPS;

(1) The first setting rule may include:

the SPS identification 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 larger than 1 and smaller than or equal to N, and the SPS identification of the Mth activated SPS is the sum of the first identification information and a set numerical value;

if the time slot where the Mth effective value is located is an uplink time slot, the Mth activated SPS can not be used for scheduling data.

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

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

the method comprises the following steps: if SLIV index value ranges from 1 to 4 and SLIV2 is invalid, the corresponding SPS-ID2 is not activated and SPS-ID 1/3/4 is activated.

The method 2 comprises the following steps: if the SLIV index value range is 1-4 and SLIV2 is invalid, the SPS-ID2 is activated but the time domain position corresponds to SLIV3; SPS-ID3 is active, but the time domain position corresponds to SLIV4, and SPS-ID4 is inactive.

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

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 the SLIV index value ranges from 1 to 4, SLIV-2 (i.e., the SLIV indicated by numeral 5 in fig. 4) is an uplink slot, SPS-ID =2 is active but data is not scheduled.

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

Such as: assuming a total of 8 HARQ process numbers, 1, 2, 3, 4, 5, 6, 7, 8, respectively; 4 PDSCHs, namely PDSCH-1, PDSCH-2, PDSCH-3 and PDSCH-4; 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, as described in scheme 1 in table 7 below.

TABLE 7

The second method comprises the following steps: averagely distributing the HARQ maximum process number to each SPS in the N SPS, wherein the process number of each SPS is Q, distributing each HARQ process number in a first range to a first activated SPS in the plurality of SPS, and sequentially distributing each HARQ process number in a second range corresponding to a previous SPS in the plurality of SPS to a next SPS until each activated SPS in the plurality of SPS is distributed with the HARQ process number; wherein Q is a value greater than 1, the first range includes HARQ process number to HARQ process number plus Q-1, and the second range includes last process number corresponding to the previous SPS plus 1 to plus Q.

Such as: assuming a total of 8 HARQ process numbers, 1, 2, 3, 4, 5, 6, 7, 8, respectively; 4 PDSCHs, namely PDSCH-1, PDSCH-2, PDSCH-3 and PDSCH-4; when 8 HARQ process numbers are allocated, mode 2 in table 7 may be used as described above in which 1 and 2 are allocated to PDSCH-1, 3 and 4 are allocated to PDSCH-2, 5 and 6 are allocated to PDSCH-3, and 7 and 8 are allocated to PDSCH-4.

It can be seen from the above embodiments that the HARQ process numbers of the N SPS are determined by the HARQ process number offset value, thereby ensuring that one control signaling can simultaneously schedule the PDSCH of multiple SPS, and improving the flexibility of channel scheduling.

Optionally, the control signaling further includes second identification information for indicating all activated SPS in the N SPS, where the second identification information is an SPS list index pointing to an SPS activation list; correspondingly, when step 202 is executed, the following implementation processes may be specifically included, but are not limited to:

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

c. determining N activated SPS according to the total number of the SPS identifications;

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

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 set rule;

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

Specifically, as shown in table 6, when the row index is 0, SLIV1, SLIV2, …, and SLIV8 are all valid values; when the row index is 1, SLIV2 and SLIV4 are invalid values, and the rest are valid values; when the row index is 2, SLIV3, and SLIV4 are invalid values, and the remaining are valid values.

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

The SPS activation list pointed to by the second identification information may refer to one SPS activation list configured by the network device through higher layer signaling. SPS identities for all activated SPS of the N SPS may be included in the SPS activation list.

Such as: the SPS activation list has 3 SPS identities, which are SPS-ID =2, SPS-ID =3, and SPS-ID =5.

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 as shown in the above table 5.

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

Wherein (1) the third setting rule includes:

the P-th SPS identifications in each SPS identification correspond to the P-th effective value in each SLIV index, and P is an integer which is greater than or equal to 1 and less than or equal to N;

when the correspondence relationship is determined according to the third setting rule, as shown in fig. 5: assuming that the SLIV index value range is 1 to 5, SLIV2 is invalid, and SPS-ID =2/3/5 is configured in the SPS activation list pointed by the second identification information, SLIV1 corresponds to SPS-ID2, SLIV3 corresponds to SPS-ID3, and SLIV4 corresponds to SPS-ID5.

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

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

(2) The fourth setting rule includes the following first mode or second mode:

the method I comprises the following steps: allocating the HARQ process number to the first activated SPS in the plurality of SPS, and adding 1 to the HARQ process number corresponding to the former SPS in the plurality of SPS to allocate to the latter SPS in sequence until each activated SPS in the plurality of SPS is allocated with the HARQ process number;

Such as: assuming a total of 8 HARQ process numbers, 1, 2, 3, 4, 5, 6, 7, 8, respectively; 4 PDSCHs, namely PDSCH-1, PDSCH-2, PDSCH-3 and PDSCH-4; when 8 HARQ process numbers are allocated, 1 and 5 may be allocated to PDSCH-1, 2 and 6 may be allocated to PDSCH-2, 3 and 7 may be allocated to PDSCH-3, and 4 and 8 may be allocated to PDSCH-4, as in scheme 1 in table 7.

The second method comprises the following steps: averagely distributing the HARQ maximum process number to each SPS in the N SPS, wherein the process number of each SPS is Q, distributing each HARQ process number in a third range to the first activated SPS in the plurality of SPS, and sequentially distributing each HARQ process number in a fourth range corresponding to the previous SPS in the plurality of SPS to the next SPS until each activated SPS in the plurality of SPS is distributed with the HARQ process number; wherein Q is a value greater than 1, the third range includes HARQ process number to HARQ process number plus Q-1, and the fourth range includes last process number corresponding to the previous SPS plus 1 to plus Q.

Such as: assuming a total of 8 HARQ process numbers, 1, 2, 3, 4, 5, 6, 7, 8, respectively; 4 PDSCHs, namely PDSCH-1, PDSCH-2, PDSCH-3 and PDSCH-4; when 8 HARQ process numbers are allocated, 1 and 2 may be allocated to PDSCH-1, 3 and 4 may be allocated to PDSCH-2, 5 and 6 may be allocated to PDSCH-3, and 7 and 8 may be allocated to PDSCH-4 as in scheme 2 of table 7.

It can be seen from the above embodiments that the SPS identifier of each activated SPS in the N SPS, the corresponding relationship between the SPS identifier of each activated SPS and the effective value in each SLIV index, and the HARQ process number of each activated SPS in the N SPS can be respectively determined by the second identifier information, the third setting rule, and the fourth setting rule, thereby ensuring that one control signaling can simultaneously schedule the PDSCHs of multiple SPS, and improving the reliability of channel scheduling.

Optionally, the channel scheduling method further includes:

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

and acquiring an SPS activation list according to the second higher layer signaling.

Specifically, the terminal device receives a second higher layer signaling sent by the network device, and may obtain 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 for indicating the TDRA table.

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

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

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

wherein RV is all 0; NDI is all 0; the indication of K1 includes:

when activated, K1 is the time slot position of PUCCH calculated from the position of the last scheduled PDSCH in the PDSCHs of N SPS;

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

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

the first situation is as follows: when a plurality of SPS are activated under the scheduling of multiple PDSCHs, K1 is the time slot position of a PUCCH calculated from the position of the last scheduled PDSCH in the PDSCHs of the N SPS;

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

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

Example one:

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

Wherein, the TDRA identification information is a row index pointing to a TDRA table, and each row in the TDRA table comprises a plurality of SLIVs; the first identification information is used for indicating the SPS activated by the first SPS in the N SPS, and is an SPS index pointing to the SPS configuration parameter set.

The specific implementation process comprises the following steps:

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

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

And (1-3) the base station determines a plurality of SLIVs used by the SPS configuration by indicating the row index through the TDRA of the DCI.

And (1-4) the terminal equipment reads the DCI and determines the number of activated SPS and the corresponding SLIV value.

(1-5) the base station indicates the first activated SPS-ID by the first identification information of the DCI, which corresponds to the valid value of the first SLIV. And adding 1 to SPS-ID of other scheduled PDSCH correspondingly, and sequentially corresponding to other SLIV valid values.

(1-6) the terminal device determines the activated plurality of SPS-IDs and the related configuration parameters by reading the DCI.

(1-7) if there is an invalid (invalid) condition in all the SLIVs of the row index indicated by the step (1-3):

the method comprises the following steps: and (4) not activating the SPS-ID corresponding to the invalid (invalid) SLIV, wherein the SPS-ID and the SLIV correspond in sequence.

Specifically, method 1 as shown in fig. 3:

TDRA = { row index 0, SLIV-1 (S =2, l = 10), SLIV-2 (invalidid), SLIV-3 (S =2, l = 10), SLIV-4 (S =2, l = 10) }. If SLIV index value ranges from 1 to 4 and SLIV2 is invalid, the corresponding SPS-ID2 is not activated and SPS-ID 1/3/4 is activated.

The method 2 comprises the following steps: and activating the SPS-ID corresponding to the invalid SLIV, and delaying the corresponding SLIV backwards to a valid SLIV value.

Specifically, method 2 as shown in fig. 3:

if the SLIV index value range is 1-4 and SLIV2 is invalid, SPS-ID2 is activated but the time domain position corresponds to SLIV3; SPS-ID3 is active, but the time domain position corresponds to SLIV4, and SPS-ID4 is inactive.

(1-8) if there is an uplink slot in all the SLIVs of the Row index (Row index) indicated in the step (1-3), then: the SPS-ID corresponding to the uplink time slot is activated effectively at this time, but the scheduling is invalid at this time.

Specifically, as shown in fig. 4:

where 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) }.

And (1-9) HARQ process allocation.

Specifically, the first method: allocating the HARQ process number to the first activated SPS in the plurality of SPS, and sequentially adding 1 to the HARQ process number corresponding to the previous SPS in the plurality of SPS to allocate to the next SPS until each activated SPS in the plurality of SPS is allocated with the HARQ process number;

and if the number of the distributed HARQ process numbers is smaller than the number of the HARQ maximum process numbers, the distributed last HARQ process number plus 1 is distributed to the first activated SPS in the plurality of SPS, the HARQ process number plus 1 corresponding to the previous SPS in the plurality of SPS is distributed to the next SPS in sequence, and the distributed number of the HARQ processes is updated until the updated number of the distributed HARQ process numbers is equal to the number of the HARQ maximum process numbers.

(1-10) when activated, the K1 value is the slot position of PUCCH calculated 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, the TDRA identification information is a row index pointing to a TDRA table, and each row in the TDRA table comprises a plurality of SLIVs; the second identification information is used to indicate all activated SPS of the N SPS and is an SPS list index pointing to an SPS activation 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 the SPS configuration, wherein the TDRA table has a plurality of SLIV values per row.

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

And (2-3) the base station determines a plurality of SLIVs used by the SPS configuration by indicating the row index through the TDRA of the DCI.

And (2-4) the terminal equipment reads the DCI and determines an SLIV value corresponding to the activated SPS.

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

The SPS configuration activation state list SPS-ConfigActivateStateList can configure at most maxNrofSPS-ActivateStateStateList, the parameters of each activation state are configured by the SPS-ConfigAactionState, and the PDSCH of the maxNrofSPS-Config SPS is contained at most. The description is as follows:
