Abstract: Certain aspects of the present disclosure relate to beam selection. An example method generally includes selecting, from a plurality of beams, a beam for uplink transmission during a particular time interval, the selecting being based on a transmission power and a radio frequency (RF) exposure for each of the plurality of beams and transmitting at least one uplink signal using the selected beam during the particular time interval.

Abstract: Method and apparatus are provided for generating and reporting actual UL transmission power. In accordance with some implementation, a UE sends a first indication of power headroom to a base station. The UE may, from the base station, one or more resources allocation for a UL transmission. UE then may determine actual transmission power to be used in the UL transmission. Upon determination, the UE may the UL transmission based on the determination and send an indication of the actual transmission power to the base station.

Abstract: Methods and systems for determining transmission power levels according to signal types and RF exposure limits. An example method generally includes determining a first transmission power for transmitting a first type of uplink (UL) signal, determining a second transmission power for transmitting a second type of UL signal based on the first transmission power, and transmitting at least one of the first UL signal according to the first transmission power or the second UL signal according to the second transmission power.

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.
