Uplink beam selection in millimeter wave subject to maximum permissible exposure constraints

Abstract:

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine, for a candidate UE uplink beam, a transmit power due to a maximum permissible exposure (MPE) constraint; estimate, for the candidate UE uplink beam, a receive power for a base station based at least in part on the transmit power due to the MPE constraint; determine a target receive power for the base station; and select the candidate UE uplink beam as an active UE uplink beam based at least in part on the estimated receive power for the base station and the target receive power for the base station. Numerous other aspects are provided.
