Abstract

A wireless device may determine whether a sidelink transmission has higher priority than an uplink transmission. The determination may be based on comparing a priority value of the sidelink transmission to a first priority threshold for ultra reliable low latency (URLLC) uplink transmissions in response to the uplink transmission being URLLC, and the determination may be based on comparing the priority value of the sidelink transmission to a second priority threshold for non-URLLC uplink transmissions in response to the uplink transmission being non-URLLC. Based on the determining, the wireless device may transmit at least one of the sidelink transmission or the uplink transmission.

First claim

What is claimed is:

1. A wireless device comprising:
one or more processors; and
memory storing instructions that, when executed by the one or more processors, cause the wireless device to:
determine whether a sidelink transmission has higher priority than an uplink transmission based on comparing:
a priority value of the sidelink transmission to a first priority threshold for ultra reliable low latency (URLLC) uplink transmissions in response to the uplink transmission being URLLC; and
the priority value of the sidelink transmission to a second priority threshold for non-URLLC uplink transmissions in response to the uplink transmission being non-URLLC; and

based on the determining, transmit at least one of the sidelink transmission or the uplink transmission.

2. The wireless device of claim 1 , wherein the instructions further cause the wireless device to receive one or more radio resource control (RRC) configuration parameters comprising:
the first priority threshold; and
the second priority threshold.

3. The wireless device of claim 1 , wherein:
the first priority threshold is for prioritization of sidelink transmissions and URLLC uplink transmissions; and
the second priority threshold is for prioritization of the sidelink transmissions and non-URLLC uplink transmissions.

4. The wireless device of claim 1 , wherein the sidelink transmission overlaps with the uplink transmission in time.

5. The wireless device of claim 1 , wherein the instructions further cause the wireless device to transmit the uplink transmission and the sidelink transmission.

6. The wireless device of claim 5 , wherein the instructions further cause the wireless device to reduce a transmission power of the uplink transmission or the sidelink transmission so that a total transmission power of the uplink transmission and the sidelink transmission does not exceed a total transmission power threshold.

7. The wireless device of claim 6 , wherein:
the transmission power of the uplink transmission is reduced based on determining that the sidelink transmission has higher priority than the uplink transmission; and
the transmission power of the sidelink transmission is reduced based on determining that the uplink transmission has higher priority than the sidelink transmission.

8. A method comprising:
determining, by a wireless device, whether a sidelink transmission has higher priority than an uplink transmission based on comparing:
a priority value of the sidelink transmission to a first priority threshold for ultra reliable low latency (URLLC) uplink transmissions in response to the uplink transmission being URLLC; and
the priority value of the sidelink transmission to a second priority threshold for non-URLLC uplink transmissions in response to the uplink transmission being non-URLLC; and

based on the determining, transmitting at least one of the sidelink transmission or the uplink transmission.

9. The method of claim 8 , further comprising receiving one or more radio resource control (RRC) configuration parameters comprising:
the first priority threshold; and
the second priority threshold.

10. The method of claim 8 , wherein:
the first priority threshold is for prioritization of sidelink transmissions and URLLC uplink transmissions; and
the second priority threshold is for prioritization of the sidelink transmissions and non-URLLC uplink transmissions.

11. The method of claim 8 , wherein the sidelink transmission overlaps with the uplink transmission in time.

12. The method of claim 8 , further comprising transmitting the uplink transmission and the sidelink transmission.

13. The method of claim 12 , further comprising reducing a transmission power of the uplink transmission or the sidelink transmission so that a total transmission power of the uplink transmission and the sidelink transmission does not exceed a total transmission power threshold.

14. The method of claim 13 , wherein:
the transmission power of the uplink transmission is reduced based on determining that the sidelink transmission has higher priority than the uplink transmission; and
the transmission power of the sidelink transmission is reduced based on determining that the uplink transmission has higher priority than the sidelink transmission.

15. A non-transitory computer-readable medium comprising instructions that, when executed by one or more processors of a wireless device, cause the wireless device to:
determine whether a sidelink transmission has higher priority than an uplink transmission based on comparing:
a priority value of the sidelink transmission to a first priority threshold for ultra reliable low latency (URLLC) uplink transmissions in response to the uplink transmission being URLLC; and
the priority value of the sidelink transmission to a second priority threshold for non-URLLC uplink transmissions in response to the uplink transmission being non-URLLC; and

based on the determining, transmit at least one of the sidelink transmission or the uplink transmission.

16. The non-transitory computer-readable medium of claim 15 , wherein the instructions further cause the wireless device to receive one or more radio resource control (RRC) configuration parameters comprising:
the first priority threshold; and
the second priority threshold.

17. The non-transitory computer-readable medium of claim 15 , wherein:
the first priority threshold is for prioritization of sidelink transmissions and URLLC uplink transmissions; and
the second priority threshold is for prioritization of the sidelink transmissions and non-URLLC uplink transmissions.

18. The non-transitory computer-readable medium of claim 15 , wherein:
the sidelink transmission overlaps with the uplink transmission in time; and
the instructions further cause the wireless device to transmit the uplink transmission and the sidelink transmission.

19. The non-transitory computer-readable medium of claim 18 , wherein the instructions further cause the wireless device to reduce a transmission power of the uplink transmission or the sidelink transmission so that a total transmission power of the uplink transmission and the sidelink transmission does not exceed a total transmission power threshold.

20. The non-transitory computer-readable medium of claim 19 , wherein:
the transmission power of the uplink transmission is reduced based on determining that the sidelink transmission has higher priority than the uplink transmission; and
the transmission power of the sidelink transmission is reduced based on determining that the uplink transmission has higher priority than the sidelink transmission.
