Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify a first transmit power limit based at least in part on at least one of a specific absorption rate limit, a maximum permissible exposure limit, or a power density limit.

A transmitting device, such as a user equipment (UE) may determine an uplink transmit power limit for a time window based on an RF limit and a duration of the time window. The device may use the power limit to determine an uplink transmit power based on a computed uplink transmission period for the time window that accounts for a time period during which the device is expected to actually transmit. The computed uplink transmission period may be based on one or more actual uplink transmission periods during one or more prior time windows, a predictive model, network signaling, or any combinations thereof.
