Abstract

Claims (59)

1. A method comprising:

selecting, by a first wireless device, first radio resources for a first sidelink transmission of the first wireless device;

receiving, from a second wireless device, sidelink control information (SCI) reserving second radio resources for a second sidelink transmission of the second wireless device;

determining, by the first wireless device, sidelink pre-emption of the first radio resources based on the first wireless device:

performing a comparison of a first priority of the first sidelink transmission and a second priority of the second sidelink transmission; and

determining a collision between the first radio resources and the second radio resources;

selecting, based on the sidelink pre-emption of the first radio resources, third radio resources for the first sidelink transmission; and

transmitting the first sidelink transmission via the third radio resources.

2. The method of claim 1 , further comprising determining the sidelink pre-emption of the first radio resources based on:

the first priority being higher than a priority threshold; and

the first priority being higher than the second priority.

3. The method of claim 1 , further comprising determining the sidelink pre-emption of the first radio resources based on the first priority being higher than the second priority.

4. The method of claim 1 , wherein the first priority and the second priority are associated with ProSe Per-Packet Priorities (PPPPs).

5. The method of claim 1 , wherein:

the first priority is associated with a logical channel priority (LCP) of the first sidelink transmission; and

the second priority is associated with a logical channel priority (LCP) of the second sidelink transmission.

6. The method of claim 1 , wherein the collision between the first radio resources and the second radio resources is a full or partial collision in time domain and in frequency domain.

7. The method of claim 1 , wherein the third radio resources do not overlap with at least one of:

the first radio resources; and

the second radio resources.

8. A first wireless device comprising:

one or more processors; and

memory storing instructions that, when executed by the one or more processors, cause the first wireless device to:

select first radio resources for a first sidelink transmission of the first wireless device;

receive, from a second wireless device, sidelink control information (SCI) reserving second radio resources for a second sidelink transmission of the second wireless device;

determine sidelink pre-emption of the first radio resources based on the first wireless device:

performing a comparison of a first priority of the first sidelink transmission and a second priority of the second sidelink transmission; and

determining a collision between the first radio resources and the second radio resources;

select, based on the sidelink pre-emption of the first radio resources, third radio resources for the first sidelink transmission; and

transmit the first sidelink transmission via the third radio resources.

9. The first wireless device of claim 8 , wherein the instructions further cause the first wireless device to determine the sidelink pre-emption of the first radio resources based on:

the first priority being higher than a priority threshold; and

the first priority being higher than the second priority.

10. The first wireless device of claim 8 , wherein the instructions further cause the first wireless device to determine the sidelink pre-emption of the first radio resources based on the first priority being higher than the second priority.

11. The first wireless device of claim 8 , wherein the first priority and the second priority are associated with ProSe Per-Packet Priorities (PPPPs).

12. The first wireless device of claim 8 , wherein:

the first priority is associated with a logical channel priority (LCP) of the first sidelink transmission; and

the second priority is associated with a logical channel priority (LCP) of the second sidelink transmission.

13. The first wireless device of claim 8 , wherein the collision between the first radio resources and the second radio resources is a full or partial collision in time domain and in frequency domain.

14. The first wireless device of claim 8 , wherein the third radio resources do not overlap with at least one of:

the first radio resources; and

the second radio resources.

15. A non-transitory computer-readable medium comprising instructions that, when executed by one or more processors of a first wireless device, cause the first wireless device to:

select first radio resources for a first sidelink transmission of the first wireless device;

receive, from a second wireless device, sidelink control information (SCI) reserving second radio resources for a second sidelink transmission of the second wireless device;

determine sidelink pre-emption of the first radio resources based on the first wireless device:

performing a comparison of a first priority of the first sidelink transmission and a second priority of the second sidelink transmission; and

determining a collision between the first radio resources and the second radio resources;

select, based on the sidelink pre-emption of the first radio resources, third radio resources for the first sidelink transmission; and

transmit the first sidelink transmission via the third radio resources.

16. The non-transitory computer-readable medium of claim 15 , wherein the instructions further cause the first wireless device to determine the sidelink pre-emption of the first radio resources based on:

the first priority being higher than a priority threshold; and

the first priority being higher than the second priority.

17. The non-transitory computer-readable medium of claim 15 , wherein the instructions further cause the first wireless device to determine the sidelink pre-emption of the first radio resources based on the first priority being higher than the second priority.

18. The non-transitory computer-readable medium of claim 15 , wherein the first priority and the second priority are associated with ProSe Per-Packet Priorities (PPPPs).

19. The non-transitory computer-readable medium of claim 15 wherein:

the first priority is associated with a logical channel priority (LCP) of the first sidelink transmission; and

the second priority is associated with a logical channel priority (LCP) of the second sidelink transmission.

20. The non-transitory computer-readable medium of claim 15 , wherein the collision between the first radio resources and the second radio resources is a full or partial collision in time domain and in frequency domain.
