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 plurality of power ranges, wherein each of the power ranges is associated with a different priority for communication between wireless devices;
receiving control information indicating a priority associated with communication between the first wireless device and a second wireless device;
selecting, based on the priority, a power range, of the plurality of power ranges;
receiving a value of a power measurement of one or more feedback channel resources; and
transmitting, by the first wireless device, based on the power range and the value of the power measurement, 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 transmitting the message to the second wireless device is performed via a resource of 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 , further comprising:
based on the power range, determining a transmission power for transmission of the message, wherein the transmitting the message uses the transmission power.
5 . The method of claim 1 , further comprising:
excluding, based on the value of the power measurement exceeding the power range and from a candidate resource set, at least one resource of the one or more feedback channel resources.
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 a resource used in the transmitting the message occurs.
7 . The method of claim 1 , wherein the control information further indicates a second priority, the method further comprising:
excluding, based on comparing the priority and the second priority, at least one feedback channel resource of the one or more feedback channel resources.
8 . A first wireless device comprising:
one or more processors; and
memory storing instructions that, when executed by the one or more processors, configure the first wireless device to:
receive at least one configuration parameter indicating a plurality of power ranges, wherein each of the power ranges is associated with a different priority for communication between wireless devices;
receive control information indicating a priority associated with communication between the first wireless device and a second wireless device;
select, based on the priority, a power range, of the plurality of power ranges;
receive a value of a power measurement of one or more feedback channel resources; and
transmit, based on the power range and the value of the power measurement, a message to the second wireless device.
9 . The first wireless device of claim 8 , wherein the instructions, when executed by the one or more processors, further configure the first wireless device to:
determine a candidate resource set comprising resources occurring in a selection time period, wherein the transmitting the message to the second wireless device is performed via a resource of the candidate resource set.
10 . The first wireless device of claim 8 , wherein the one or more feedback channel resources comprise one or more physical sidelink feedback channel (PSFCH) resources.
11 . The first wireless device of claim 8 , wherein the instructions, when executed by the one or more processors, further configure the first wireless device to:
based on the power range, determine a transmission power for transmission of the message, wherein the transmitting the message uses the transmission power.
12 . The first wireless device of claim 8 , wherein the instructions, when executed by the one or more processors, further configure the first wireless device to:
exclude, based on the value of the power measurement exceeding the power range and from a candidate resource set, at least one resource of the one or more feedback channel resources.
13 . The first wireless device of claim 8 , 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 a resource used in the transmitting the message occurs.
14 . The first wireless device of claim 8 , wherein the control information further indicates a second priority, and wherein the instructions, when executed by the one or more processors, further configure the first wireless device to:
exclude, based on comparing the priority and the second priority, at least one feedback channel resource of the one or more feedback channel resources.
15 . One or more non-transitory computer readable medium storing instructions that, when executed, configure a first wireless device to:
receive at least one configuration parameter indicating a plurality of power ranges, wherein each of the power ranges is associated with a different priority for communication between wireless devices;
receive control information indicating a priority associated with communication between the first wireless device and a second wireless device;
select, based on the priority, a power range, of the plurality of power ranges;
receive a value of a power measurement of one or more feedback channel resources; and
transmit, based on the power range and the value of the power measurement, a message to the second wireless device.
16 . The one or more non-transitory computer readable medium of claim 15 , wherein the instructions, when executed, further configure the first wireless device to:
determine a candidate resource set comprising resources occurring in a selection time period, wherein the transmitting the message to the second wireless device is performed via a resource of the candidate resource set.
17 . The one or more non-transitory computer readable medium of claim 15 , wherein the one or more feedback channel resources comprise one or more physical sidelink feedback channel (PSFCH) resources.
18 . The one or more non-transitory computer readable medium of claim 15 , wherein the instructions, when executed, further configure the first wireless device to:
based on the power range, determine a transmission power for transmission of the message, wherein the transmitting the message uses the transmission power.
19 . The one or more non-transitory computer readable medium of claim 15 , wherein the instructions, when executed, further configure the first wireless device to:
exclude, based on the value of the power measurement exceeding the power range and from a candidate resource set, at least one resource of the one or more feedback channel resources.
20 . The one or more non-transitory computer readable medium of claim 15 , 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 a resource used in the transmitting the message occurs.
21 . The one or more non-transitory computer readable medium of claim 15 , wherein the control information further indicates a second priority, and wherein the instructions, when executed, further configure the first wireless device to:
exclude, based on comparing the priority and the second priority, at least one feedback channel resource of the one or more feedback channel resources.
