Abstract

This specification provides a resource determining method and an apparatus, to optimize sidelink transmission performance. In this specification, a first communication apparatus may receive preferred resource information and/or non-preferred resource information, determine a transmission resource based on received resource information and a type of the first communication apparatus, and perform sidelink transmission by using the transmission resource. First resource information can indicate a high-interference or high-usage resource and/or a low-interference or low-usage resource. The first communication apparatus can select, based on the type of the first communication apparatus, a resource with relatively low interference to perform sidelink transmission. This improves sidelink transmission performance.

First claim

What is claimed is:

1. A resource determining method comprising:
obtaining first resource information, wherein the first resource information is used to indicate at least one of a first-type resource or a second-type resource;
determining a transmission resource based on a type of a first communication apparatus and the first resource information; and
transmitting sidelink transmission data based on the transmission resource;
wherein the type of the first communication apparatus comprises a no-sensing type, a partial-sensing type, or a full-sensing type;
wherein a signal strength of the first-type resource is not less than a first threshold; and
wherein a signal strength of the second-type resource is not greater than a third threshold.

2. The method according to claim 1 , wherein the obtaining first resource information comprises:
receiving the first resource information from a second communication apparatus; and
wherein the transmitting sidelink transmission data based on the transmission resource comprises:
sending the sidelink transmission data to the second communication apparatus based on the transmission resource.

3. The method according to claim 1 , wherein the determining the transmission resource based on the type of the first communication apparatus and the first resource information comprises:
determining that the first communication apparatus is of the no-sensing type; and
determining the second-type resource, or a resource other than the first-type resource, as the transmission resource.

4. The method according to claim 1 , wherein the determining the transmission resource based on the type of the first communication apparatus and the first resource information comprises:
determining that the type of the first communication apparatus is the partial-sensing type or the full-sensing type;
obtaining resources in a resource pool of the first communication apparatus; and
determining, from the resources in the resource pool of the first communication apparatus, the second resource, or a resource other than the first resource, as the transmission resource;
wherein the first communication apparatus transmits the sidelink transmission data based on a resource comprised in the resource pool.

5. The method according to claim 1 , wherein the first-type resource is a non-recommended resource, and the second-type resource is a recommended resource.

6. The method according to claim 1 , wherein the determining the transmission resource based on the type of the first communication apparatus and the first resource information comprises determining a resource other than the first-type resource or the second-type resource as the transmission resource.

7. The method according to claim 1 , wherein there are a plurality of second-type resources, and the determining the transmission resource comprises:
selecting a transmission resource from the plurality of second-type resources in a random selection manner.

8. The method according to claim 1 , wherein the first resource information is related to a location of the first communication apparatus.

9. A first communication apparatus comprising:
a processor; and
a non-transitory computer-readable storage medium storing a program to be executed by the processor, the program including instructions for:
obtaining first resource information, wherein the first resource information indicates a first-type resource or a second-type resource;
determining a transmission resource based on a type of the first communication apparatus and the first resource information; and
transmitting sidelink transmission data based on the transmission resource;
wherein the type of the first communication apparatus comprises a no-sensing type, a partial-sensing type, or a full-sensing type;
wherein a signal strength of the first-type resource is not less than a first threshold; and
wherein a signal strength of the second-type resource is not greater than a third threshold.

10. The first communication apparatus according to claim 9 , wherein the obtaining first resource information comprises:
receiving the first resource information from a second communication apparatus; and
wherein the transmitting sidelink transmission data based on the transmission resource comprises:
sending the sidelink transmission data to the second communication apparatus based on the transmission resource.

11. The communication apparatus according to claim 9 , wherein the determining the transmission resource based on the type of the first communication apparatus and the first resource information comprises:
determining that the first communication apparatus is of the no-sensing type; and
determining the second-type resource, or a resource other than the first-type resource, as the transmission resource.

12. The communication apparatus according to claim 9 , wherein the determining the transmission resource based on the type of the first communication apparatus and the first resource information comprises:
determining that the type of the first communication apparatus is the partial-sensing type or the full-sensing type;
obtaining resources in a resource pool of the first communication apparatus; and
determining, from the resources in the resource pool of the first communication apparatus, the second resource, or a resource other than the first resource, as the transmission resource;
wherein the first communication apparatus transmits the sidelink transmission data based on a resource comprised in the resource pool.

13. The communication apparatus according to claim 9 , wherein the first-type resource is a non-recommended resource, and the second-type is a recommended resource.

14. The communication apparatus according to claim 9 , wherein the determining the transmission resource comprises:
determining a resource other than the first-type resource or the second-type resource as the transmission resource.

15. The communication apparatus according to claim 9 , wherein there are a plurality of second-type resources, and the determining the transmission resource comprises:
selecting a transmission resource from the plurality of second-type resources in a random selection manner.

16. The communication apparatus according to claim 9 , wherein the first resource information is related to a location of the first communication apparatus.

17. A non-transitory computer-readable storage medium storing a program to be executed by a processor, the program including instructions for:
obtaining first resource information, wherein the first resource information indicates at least one of a first-type resource or a second-type resource;
determining a transmission resource based on a type of a first communication apparatus and the first resource information; and
transmitting sidelink transmission data based on the transmission resource;
wherein the type of the first communication apparatus comprises a no-sensing type, a partial-sensing type, or a full-sensing type;
wherein a signal strength of the first-type resource is not less than a first threshold; and
wherein a signal strength of the second-type resource is not greater than a third threshold.

18. The non-transitory computer-readable medium according to claim 17 , wherein the instructions for obtaining first resource information comprise instructions for:
receiving the first resource information from a second communication apparatus; and
wherein the instructions for transmitting sidelink transmission data based on the transmission resource comprise instructions for:
