Abstract
In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. In certain configurations, the apparatus may be a user equipment (UE). The apparatus may receive configuration information for UL and DL transmissions from another device such as a base station. The apparatus may determine a maximum duty cycle of the UL transmission based on the configuration information. Based on the determined UL maximum duty cycle, the apparatus may determine a transmit power limit for the UL transmission. In one aspect, the apparatus may determine the UL transmit power limit by dividing the power corresponding to a maximum permissible exposure (MPE) limit by the determined maximum UL duty cycle. The apparatus may leverage the forward knowledge of the UL duty cycle to transmit at a power level that complies with the MPE limit while avoiding the poor uplink range associated with static power back-off.
