Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify an available energy for uplink transmission of a plurality of communication links of the UE. The UE may configure, from the available energy, a first set of energy allocations for the plurality of communication links. The UE may configure a second set of energy allocations for one or more communication links of the plurality of communication links, wherein the second set of energy allocations are allocated from a remainder of the available energy after the first set of energy allocations are allocated. The UE may transmit based at least in part on at least one of the first set of energy allocations or the second set of energy allocations. Numerous other aspects are described.

Abstract: Techniques and apparatus for beam selection in compliance with radio frequency (RF) exposure limits. A method that may be performed by a wireless device includes receiving, from another wireless device, a plurality of signals via a plurality of beams; measuring a received signal power for each of the beams, based on the received plurality of signals; determining a transmit power limit for each of the beams based at least in part on an RF exposure limit; determining an estimation of a signal quality at the other wireless device for each of the beams based at least in part the received signal powers and the transmit power limits; selecting one of the beams based on the estimations of the signal qualities for the beams; and transmitting a signal via the selected beam.

Abstract: In certain aspects, a method implemented in a wireless device includes determining a specific absorption rate (SAR) distribution for a first wireless communication technology, determining a power density (PD) distribution for a second wireless communication technology, and combining the SAR distribution and the PD distribution to generate a combined RF exposure distribution. The method also includes determining at least one first maximum allowable power level and at least one second maximum allowable power level for a future time slot based on the combined RF exposure distribution, setting at least one transmission power limit for a first transmitter in the future time slot based on the at least one first maximum allowable power level, and setting at least one transmission power limit for a second transmitter in the future time slot based on the at least one second maximum allowable power level.

Abstract: Certain aspects of the present disclosure provide techniques for exception-robust time-averaged radio frequency (RF) exposure compliance continuity. A method that may be performed by a user equipment (UE) generally includes transmitting a first signal at a first transmission power based on time-averaged RF exposure measurements over a time window and storing RF exposure information associated with the time window. The method may also include detecting that an exception event associated with the UE occurred and transmitting a second signal at a second transmission power based at least in part on the stored RF exposure information in response to the detection of the event.

Abstract: A device and method for determining power density measurements of electromagnetic (EM) transmissions from an antenna of a wireless electronic device are disclosed. The method can include determining one or more worst case configurations within an exposure plane based on a power density distribution of the antenna in free space. The method can also include measuring power density distribution across a first plane at a first distance from the exposure plane and across a second plane at a second distance from the exposure plane. The method can also include first back transforming power density distribution of the first plane to the second plane, second back transforming power density distribution from the first plane to the exposure plane, and third back transforming power density distribution from the second plane to the exposure plane, for the one or more worst case configurations.

Abstract: Certain aspects of the present disclosure provide techniques and apparatus for filter-based time-averaging radio frequency (RF) exposure evaluation. An example method of wireless communication includes determining an effective time-averaged transmit power associated with one or more past transmissions using a filter. The method further includes transmitting a signal in a time interval at a transmit power determined based at least in part on the effective time-averaged transmit power in compliance with an RF exposure limit.

Abstract: Techniques and apparatus for generating a compressed radio frequency (RF) exposure map and using such a compressed RF exposure map for determining a transmit power to meet RF exposure compliance limits are described. An example method generally includes obtaining a first RF exposure map associated with at least one antenna of a wireless device and converting the first RF exposure map to a second RF exposure map. The second RF exposure map is compressed compared to the first RF exposure map. Another example method includes accessing an RF exposure map associated with at least one antenna of the wireless device. The RF exposure map includes a representation of a maximum RF exposure for a region of the RF exposure map. The method also includes transmitting, from the antenna(s), a signal at a transmit power determined based on the RF exposure map in compliance with an RF exposure limit.
