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, at least one configuration parameter indicating a set of received power ranges associated with a first priority and a second priority, wherein the first priority is associated with communication between the first wireless device and a second wireless device;
receiving, via a first resource, control information indicating:
the second priority; and
a reservation of a second resource;
determining a received power range, from the set of received power ranges, comprising a value of a received power measurement of one or more feedback channel resources associated with the first resource;
based on the received power range and at least one of the first priority or the second priority, determining a third resource for communication between the first wireless device and the second wireless device; and
transmitting, by the first wireless device via the third resource, a message to the second wireless device.
2. The method of claim 1 , further comprising:
determining a candidate resource set comprising resources occurring in a selection time period, wherein the determining the third resource comprises selecting the third resource from the candidate resource set.
3. The method of claim 1 , wherein the one or more feedback channel resources comprise one or more physical sidelink feedback channel (PSFCH) resources.
4. The method of claim 1 , wherein the determining the third resource comprises excluding, from selection as the third resource, each resource, of the one or more feedback channel resources, corresponding to a received power range satisfying a threshold.
5. The method of claim 1 , further comprising:
based on the received power range, determining a transmission power for transmission of the message, wherein the transmitting the message uses the transmission power.
6. The method of claim 1 , wherein the at least one configuration parameter further indicates:
a sensing time period for the receiving the control information; and
a selection time period during which the second resource occurs and during which the third resource occurs.
7. The method of claim 1 , wherein the second priority is higher than the first priority, and wherein the determining the third resource for communication with the second wireless device comprises excluding, from among a candidate resource set comprising the third resource, one or more resources associated with the second priority.
8. A method comprising:
receiving, by a first wireless device, at least one configuration parameter for selection of one or more resources to communicate with a second wireless device, wherein the at least one configuration parameter indicates a set of received power ranges;
receiving, via a first resource occurring in a sensing time period, control information indicating:
a reservation of a second resource; and
a priority associated with the second resource;
determining a received power range, from the set of received power ranges, comprising a value of a received power measurement of one or more feedback channel resources associated with the first resource;
based on the received power range and the priority, determining a third resource; and
transmitting, by the first wireless device via the third resource, a message to the second wireless device.
9. The method of claim 8 , further comprising:
determining a candidate resource set comprising resources occurring in a selection time period, wherein the determining the third resource comprises selecting the third resource from the candidate resource set.
10. The method of claim 8 , further comprising:
determining a received power of one or more feedback channel resources associated with the second resource, wherein the determining the third resource is further based on the received power of the one or more feedback channel resources associated with the second resource.
11. The method of claim 8 , wherein the one or more feedback channel resources comprises one or more physical sidelink feedback channel (PSFCH) resources.
12. The method of claim 8 , wherein the determining the third resource comprises excluding, from selection as the third resource, each resource, of the one or more feedback channel resources, corresponding to a received power range satisfying a threshold.
13. The method of claim 8 , further comprising:
based on the received power range, determining a transmission power for transmission of the message, wherein the transmitting the message uses the transmission power.
14. The method of claim 8 , wherein the priority associated with the second resource comprises a first priority that is higher than a second priority associated with communication between the first wireless device and the second wireless device, and wherein the determining the third resource comprises excluding, from among a candidate resource set comprising the third resource, one or more resources associated with the first priority.
15. A method comprising:
receiving, by a first wireless device, an indication of a set of received power ranges;
receiving, by the first wireless device via a first resource, control information indicating:
a reservation of a second resource; and
a first priority associated with the second resource;
determining a received power range, from the set of received power ranges, comprising a value of a received power measurement of one or more feedback channel resources associated with the first resource;
determining, based on the received power range and based on at least one of the first priority or a second priority associated with a communication between the first wireless device and a second wireless device, a third resource; and
transmitting, by the first wireless device via the third resource, a message to the second wireless device.
16. The method of claim 15 , further comprising:
determining a candidate resource set comprising resources occurring in a selection time period, wherein the determining the third resource comprises selecting the third resource from the candidate resource set.
17. The method of claim 15 , further comprising:
determining a received power of one or more feedback channel resources associated with the second resource, wherein the determining the third resource is further based on the received power of the one or more feedback channel resources associated with the second resource.
18. The method of claim 15 , wherein the one or more feedback channel resources comprises one or more physical sidelink feedback channel (PSFCH) resources.
19. The method of claim 15 , further comprising:
based on the received power range, determining a transmission power for transmission of the message, wherein the transmitting the message uses the transmission power.
20. The method of claim 15 , further comprising:
receiving at least one configuration parameter for selection of one or more resources to communicate with the second wireless device, wherein: the at least one configuration parameter indicates the first priority;
the first priority is higher than the second priority; and
the determining the third resource comprises excluding, from among a candidate resource set comprising the third resource, one or more resources associated with the first priority.
