Long-term measurement for receiver-assisted channel access
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a trigger for obtaining long-term measurements associated with receiver-assisted channel access. The UE may obtain a long-term measurement for a channel after receiving the trigger. The UE may transmit an indication of the long-term measurement or a preferred beam that is selected based at least in part on the long-term measurement. Numerous other aspects are described.

a memory; and
one or more processors, coupled to the memory, configured to:
receive a trigger for obtaining long-term measurements associated with receiver-assisted channel access; obtain a long-term measurement for a channel after receiving the trigger; and
transmit an indication of a preferred beam that is selected from among configured beams of the UE based at least in part on the long-term measurement, wherein at least one of: the preferred beam accounts for interference cancellation, or the preferred beam is selected based at least in part on a UE capability for interference cancellation.
2 . The UE of claim 1 , wherein the long-term measurement includes a received signal strength indicator (RSSI) measurement for one or more configured beams of the UE.
3 . The UE of claim 2 , wherein the long-term measurement is obtained over a period of time that is greater in duration than a period of time associated with an RSSI measurement timing configuration.
4 . The UE of claim 1 , wherein the long-term measurement is obtained over a period of time that is greater in duration than a period of time associated with a channel state information reference signal measurement or a period of time associated with a synchronization signal block measurement.
5 . The UE of claim 1 , wherein the one or more processors are configured to obtain multiple long-term measurements over a period of time that is greater in duration than a channel state information reference signal measurement or a synchronization signal block measurement, and transmit the multiple long-term measurements.
6 . The UE of claim 1 , wherein the one or more processors, to obtain the long-term measurement, are configured to obtain an interference measurement associated with a physical layer measurement.
7 . The UE of claim 1 , wherein the one or more processors are configured to transmit an interference measurement for a configured beam of the UE.
8 . The UE of claim 1 , wherein the one or more processors are configured to transmit information indicating an amount of samples where the long-term measurement satisfies a measurement threshold.
9 . A base station for wireless communication, comprising:
a memory; and
one or more processors, coupled to the memory, configured to:
configure a user equipment (UE) for obtaining long-term measurements associated with received-assisted channel access; transmit a trigger for obtaining long-term measurements; and
receive an indication of a preferred beam that is selected from among configured beams of the UE based at least in part on the long-term measurement, wherein at least one of: the preferred beam accounts for interference cancellation, or the preferred beam is selected based at least in part on a UE capability for interference cancellation.
10 . The base station of claim 9 , wherein the one or more processors are configured to access a channel based at least in part on the long-term measurement or the preferred beam.
11 . The base station of claim 9 , wherein the long-term measurement includes a received signal strength indicator (RSSI) measurement for one or more configured beams of the UE.
12 . The base station of claim 11 , wherein the long-term measurement is obtained over a period of time that is greater in duration than a period of time associated with an RSSI measurement timing configuration.
13 . The base station of claim 9 , wherein the long-term measurement is obtained over a period of time that is greater in duration than a channel state information reference signal measurement or a synchronization signal block measurement.
14 . The base station of claim 9 , wherein the one or more processors are configured to receive multiple long-term measurements obtained over a period of time that is greater in duration than a channel state information reference signal measurement or a synchronization signal block measurement.
15 . The base station of claim 9 , wherein the one or more processors are configured to receive an interference measurement associated with a physical layer measurement.
16 . The base station of claim 9 , wherein the one or more processors are configured to receive an interference measurement for a configured beam of the UE.
17 . A method of wireless communication performed by a user equipment (UE), comprising:
