Abstract

A method for configured grant configuration, a terminal, and a network-side device are provided. The method includes: receiving radio resource control (RRC) signalling transmitted by a network-side device, where the RRC signalling is used to configure a mapping relationship between a plurality of configured grant configuration sets and a plurality of indexes; receiving downlink control information (DCI) and determining, based on the mapping relationship, a configured grant configuration set corresponding to a target index that is indicated by the DCI; and deactivating configured grant configurations included in the configured grant configuration set that is determined.

First claim

receiving downlink control information (DCI) and determining, based on the mapping relationship, a set of configured grant configurations corresponding to a target index that is indicated by the DCI, wherein the target index is any one of the plurality of indexes; and
deactivating configured grant configurations comprised in the set of configured grant configurations that is determined;
wherein a quantity of bits N to be occupied by the target index is configured by the network-side device, and a value of N is configured by the network-side device by using the RRC signalling.

2. The method according to claim 1 , wherein the determining, based on the mapping relationship, the set of configured grant configurations corresponding to the target index that is indicated by the DCI comprises:
determining the set of configured grant configurations based on a target parameter of the DCI and the target index indicated by the DCI.

3. The method according to claim 2 , wherein the target parameter of the DCI comprises at least one of the following:
a format of the DCI;
a radio network temporary identifier (RNTI) corresponding to the DCI;
a control resource set corresponding to the DCI; or
a search space corresponding to the DCI.

4. The method according to claim 1 , wherein the method further comprises:
determining a transmission occasion start position of each configured grant configuration in the set of configured grant configurations based on first indication information indicated by the DCI and first radio resource control (RRC) configuration information, wherein the first indication information is used to indicate a transmission occasion start position of a first configured grant configuration, and the first configured grant configuration is any one configuration in the set of configured grant configurations; and
the first RRC configuration information is used to configure an offset value for transmission occasion start positions of the configured grant configurations in the set of configured grant configurations.

5. The method according to claim 1 , wherein the method further comprises:
determining a transmission occasion start position of each configured grant configuration in the set of configured grant configurations based on second RRC configuration information, first indication information indicated by the DCI, and second indication information indicated by the DCI; wherein
the second RRC configuration information is used to configure an offset value set for transmission occasion start positions of the configured grant configurations in the set of configured grant configurations, and the offset value set comprises at least two offset values;
the first indication information is used to indicate a transmission occasion start position of a first configured grant configuration, and the first configured grant configuration is any one configuration in the set of configured grant configurations; and
the second indication information is used to indicate one offset value in the offset value set.

6. The method according to claim 1 , wherein different configured grant configurations correspond to different demodulation reference signal (DMRS) parameters; and
each DMRS parameter comprises at least one of the following:
a DMRS port;
an orthogonal mask (OCC) used for a DMRS port; or
a DMRS scrambling identifier.

7. A non-transitory computer-readable storage medium, wherein a computer program is stored in the non-transitory computer-readable storage medium, the computer program is executed by a processor to implement the method for configured grant configuration according to claim 1 .

8. The non-transitory computer-readable storage medium according to claim 7 , wherein the computer program is further executed by a processor to implement:
determining a transmission occasion start position of each configured grant configuration in the set of configured grant configurations based on first indication information indicated by the DCI and first radio resource control (RRC) configuration information, wherein
the first indication information is used to indicate a transmission occasion start position of a first configured grant configuration, and the first configured grant configuration is any one configuration in the set of configured grant configurations; and
the first RRC configuration information is used to configure an offset value for transmission occasion start positions of the configured grant configurations in the set of configured grant configurations.

9. The non-transitory computer-readable storage medium according to claim 7 , wherein the computer program is further executed by a processor to implement:
determining a transmission occasion start position of each configured grant configuration in the set of configured grant configurations based on second RRC configuration information, first indication information indicated by the DCI, and second indication information indicated by the DCI; wherein
the second RRC configuration information is used to configure an offset value set for transmission occasion start positions of the configured grant configurations in the set of configured grant configurations, and the offset value set comprises at least two offset values;
the first indication information is used to indicate a transmission occasion start position of a first configured grant configuration, and the first configured grant configuration is any one configuration in the set of configured grant configurations; and
the second indication information is used to indicate one offset value in the offset value set.

10. A terminal, comprising a processor, a memory, and a computer program stored in the memory and capable of running on the processor, wherein when the computer program is executed by the processor, the processor is configured to implement following steps:
receiving radio resource control (RRC) signalling transmitted by a network-side device, wherein the RRC signalling is used to configure a mapping relationship between a plurality of sets of configured grant configurations and a plurality of indexes, wherein each index corresponds to one set of configured grant configurations, and each set of configured grant configurations comprises at least two configured grant configurations;
receiving downlink control information (DCI) and determining, based on the mapping relationship, a set of configured grant configurations corresponding to a target index that is indicated by the DCI, wherein the target index is any one of the plurality of indexes; and
