Wireless resource selection
Wireless resources may be determined for communications between wireless devices. A wireless device may select resources based on measuring one or more channels (e.g., associated with sidelink transmission, feedback transmission, etc.). Resource selection may comprise exclusion of certain resources being used for other communications and/or exclusion or selection of resources based on one or more priorities.
1. A method comprising:
receiving, by a first wireless device from a second wireless device and via a physical sidelink feedback channel (PSFCH), feedback associated with a first resource, wherein the first resource is for a first sidelink transmission to the second wireless device;
determining, for a second sidelink transmission via a second resource and based on the feedback, that the first resource overlaps the second resource; and
transmitting the second sidelink transmission via a third resource selected from candidate resources of a candidate resource set that excludes at least a portion of the first resource that overlaps with the second resource.
2. The method of claim 1 , wherein the first sidelink transmission is from a third wireless device to the second wireless device.
3. The method of claim 1 , wherein the second sidelink transmission is to a third wireless device.
4. The method of claim 1 , wherein the determining that the first resource overlaps with the second resource comprises determining that a received power of the feedback, associated with the first resource, is greater than a threshold.
5. The method of claim 1 , further comprising receiving control information indicating assignment of the first resource for the first sidelink transmission to the second wireless device.
6. The method of claim 1 , further comprising receiving, by the first wireless device, at least one configuration parameter for selection of one or more resources for communication, wherein the at least one configuration parameter indicates a sensing time period and a selection time period, wherein:
the receiving the feedback comprises receiving the feedback in the sensing time period; and
the transmitting the second sidelink transmission via the third resource comprises transmitting the second sidelink transmission in the selection time period.
7. The method of claim 1 , further comprising:
receiving an indication of a priority associated with the first resource, wherein the transmitting the second sidelink transmission via the third resource is further based on at least one of:
the priority associated with the first resource; or
a priority associated with the second sidelink transmission.
8. The method of claim 1 , wherein the determining that the first resource overlaps the second resource comprises determining that the first resource overlaps the second resource in at least one of time domain or frequency domain.
9. 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:
receive, from a second wireless device and via a physical sidelink feedback channel (PSFCH), feedback associated with a first resource, wherein the first resource is for a first sidelink transmission to the second wireless device;
determine, for a second sidelink transmission via a second resource and based on the feedback, that the first resource overlaps the second resource; and
transmit the second sidelink transmission via a third resource selected from candidate resources of a candidate resource set that excludes at least a portion of the first resource that overlaps with the second resource.
10. The first wireless device of claim 9 , wherein the first sidelink transmission is from a third wireless device to the second wireless device.
11. The first wireless device of claim 9 , wherein the second sidelink transmission is to a third wireless device.

The first wireless device of claim 9 , wherein the instructions that, when executed by the one or more processors, cause the first wireless device to determine that the first resource overlaps with the second resource, cause the first wireless device to determine that the first resource overlaps with the second resource by determining that a received power of the feedback, associated with the first resource, is greater than a threshold.
13. The first wireless device of claim 9 , wherein the instructions, when executed by the one or more processors, further cause the first wireless device to receive control information indicating assignment of the first resource for the first sidelink transmission to the second wireless device.
14. The first wireless device of claim 9 , wherein the instructions, when executed by the one or more processors, further cause the first wireless device to receive at least one configuration parameter for selection of one or more resources for communication, wherein the at least one configuration parameter indicates a sensing time period and a selection time period; and
wherein the instructions that, when executed by the one or more processors, cause the wireless device to receive the feedback, cause the wireless device to receive the feedback in the sensing time period; and

15. The first wireless device of claim 9 , wherein the instructions, when executed by the one or more processors, further cause the first wireless device to receive an indication of a priority associated with the first resource; and
wherein the instructions that, when executed by the one or more processors, cause the wireless device to transmit the second sidelink transmission via the third resource, cause the wireless device to transmit the second sidelink transmission via the third resource based on at least one of:
the priority associated with the first resource; or
a priority associated with the second sidelink transmission.
16. The first wireless device of claim 9 , wherein the instructions that, when executed by the one or more processors, cause the first wireless device to determine that the first resource overlaps the second resource, cause the first wireless device to determine that the first resource overlaps the second resource by determining that the first resource overlaps the second resource in at least one of time domain or frequency domain.
17. A non-transitory computer readable medium storing instructions that, when executed, configure a first wireless device to:
receive, from a second wireless device and via a physical sidelink feedback channel (PSFCH), feedback associated with a first resource, wherein the first resource is for a first sidelink transmission to the second wireless device;
