Abstract

A physical sidelink feedback information determining method and a communication device are provided. The method includes: determining target physical sidelink feedback information according to a target sidelink channel transmission resource associated with a target uplink channel, where the target sidelink channel transmission resource is determined according to a first time interval, and the first time interval is a time interval between the target sidelink channel transmission resource and the target uplink channel.

Claims (32)

1. A physical sidelink feedback information determining method, wherein the method is performed by a communication device and comprises:

determining target physical sidelink feedback information according to a target sidelink channel transmission resource associated with a target uplink channel, wherein the target sidelink channel transmission resource is determined according to a first time interval, and the first time interval is a time interval between the target sidelink channel transmission resource and the target uplink channel, a target sidelink channel of the target sidelink channel transmission resource comprises a Physical Sidelink Shared CHannel (PSSCH) or a Physical Sidelink Control CHannel (PSCCH),

wherein the first time interval is determined according to a second time interval, and the second time interval is a time interval between a target Physical Sidelink Feedback CHannel (PSFCH) and the target uplink channel.

2. The method according to claim 1 , wherein the determining the target physical sidelink feedback information comprises:

determining the target sidelink feedback information according to feedback information corresponding to the target sidelink channel transmission resource.

3. The method according to claim 1 , wherein the determining the first time interval according to the second time interval comprises:

determining the first time interval according to the second time interval and a third time interval between a target sidelink channel and the PSFCH.

4. The method according to claim 3 , wherein the third time interval is determined according to at least one of a minimum time interval between the target sidelink channel and the PSFCH, or a period of the PSFCH.

5. The method according to claim 3 , wherein the determining the first time interval according to the second time interval and a third time interval between a target sidelink channel and the PSFCH comprises: determining a sum of the third time interval and the second time interval which is scaled up or scaled down as the first time interval.

6. The method according to claim 1 , wherein when there is no PSFCH at a position corresponding to the second time interval, a target sidelink channel transmission resource corresponding to the second time interval does not belong to the target sidelink channel transmission resource.

7. A communication device, comprising:

a memory storing computer-readable instructions; and

a processor coupled to the memory and configured to execute the computer-readable instructions, wherein the computer-readable instructions, when executed by the processor, cause the processor to perform operations comprising:

determining target physical sidelink feedback information according to a target sidelink channel transmission resource associated with a target uplink channel, wherein the target sidelink channel transmission resource is determined according to a first time interval, and the first time interval is a time interval between the target sidelink channel transmission resource and the target uplink channel, a target sidelink channel of the target sidelink channel transmission resource comprises a Physical Sidelink Shared CHannel (PSSCH) or a Physical Sidelink Control CHannel (PSCCH),

wherein the first time interval is determined according to a second time interval, and the second time interval is a time interval between a target Physical Sidelink Feedback CHannel PSFCH) and the target uplink channel.

8. The communication device according to claim 7 , wherein the determining the target physical sidelink feedback information comprises:

determining the target sidelink feedback information according to feedback information corresponding to the target sidelink channel transmission resource.

9. The communication device according to claim 7 , wherein when there is no PSFCH at a position corresponding to the second time interval, a target sidelink channel transmission resource corresponding to the second time interval does not belong to the target sidelink channel transmission resource.

10. The communication device according to claim 7 , wherein the determining the first time interval according to the second time interval comprises:

determining the first time interval according to the second time interval and a third time interval between a target sidelink channel and the PSFCH.

11. The communication device according to claim 10 , wherein the third time interval is determined according to at least one of a minimum time interval between the target sidelink channel, or the PSFCH and a period of the PSFCH.

12. The communication device according to claim 10 , wherein the determining the first time interval according to the second time interval and a third time interval between a target sidelink channel and the PSFCH comprises:

determining a sum of the third time interval and the second time interval which is scaled up or scaled down as the first time interval.

13. A non-transient computer-readable storage medium, wherein the non-transient computer-readable storage medium stores a computer program, and when the computer program is executed by a processor, cause the processor to perform operations comprising:

determining target physical sidelink feedback information according to a target sidelink channel transmission resource associated with a target uplink channel, wherein the target sidelink channel transmission resource is determined according to a first time interval, and the first time interval is a time interval between the target sidelink channel transmission resource and the target uplink channel, a target sidelink channel of the target sidelink channel transmission resource comprises a Physical Sidelink Shared CHannel (PSSCH) or a Physical Sidelink Control CHannel (PSCCH),

wherein the first time interval is determined according to a second time interval, and the second time interval is a time interval between a target Physical Sidelink Feedback CHannel (PSFCH) and the target uplink channel.

14. The non-transient computer-readable storage medium according to claim 13 , wherein the determining the first time interval according to the second time interval comprises:

determining the first time interval according to the second time interval and a third time interval between a target sidelink channel and the PSFCH.

15. The non-transient computer-readable storage medium according to claim 14 , wherein the third time interval is determined according to at least one of a minimum time interval between the target sidelink channel and the PSFCH or a period of the PSFCH.

16. The non-transient computer-readable storage medium according to claim 14 , wherein the determining the first time interval according to the second time interval and a third time interval between a target sidelink channel and the PSFCH comprises:

determining a sum of the third time interval and the second time interval which is scaled up or scaled down as the first time interval.

17. The non-transient computer-readable storage medium according to claim 13 , wherein when there is no PSFCH at a position corresponding to the second time interval, a target sidelink channel transmission resource corresponding to the second time interval does not belong to the target sidelink channel transmission resource.
