Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine, for a radio associated with the UE, an energy usage in a past transmit interval. The UE may determine, for the radio, a requested usage-aware energy reservation based at least in part on the energy usage in the past transmit interval. The UE may assign, for a next transmit interval, an energy budget limit for the radio based at least in part on the requested usage-aware energy reservation. The UE may transmit, via the radio, an uplink transmission based at least in part on the energy budget limit. Numerous other aspects are described.

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 transmission during a particular time interval within a time window, 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 signal using the selected beam during the particular time interval.

Abstract: Methods, systems, and devices for wireless communications are described that support techniques for transmission power determination for radio frequency (RF) exposure compliance. 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. The device may transmit one or more uplink transmissions during the time window using the determined uplink transmit power.
