Abstract: Certain aspects of the present disclosure provide techniques for operating a wireless communication device pursuant to radio frequency (RF) exposure with antenna grouping. An example method of wireless communication by a user equipment generally includes accessing a stored backoff factor associated with an antenna group among a plurality of antenna groups. The method also includes transmitting, from at least one transmit antenna in the antenna group, a signal at a transmission power level based on the backoff factor in compliance with an RF exposure requirement.

Abstract: Techniques and apparatus for configurable radio frequency (RF) exposure compliance based on region. An example method of wireless communication by a user equipment (UE) generally includes identifying a region in which the UE is located, selecting at least one of a mode or one or more parameters for RF exposure compliance based on the identified region, and transmitting a signal at a transmission power level based at least in part on the at least one of the selected mode or the selected one or more parameters.

Abstract: Certain aspects of the present disclosure provide techniques and apparatus for a mobile satellite communications application that is aware of radio frequency (RF) exposure. An example method of wireless communication by a wireless device includes determining an RF exposure budget for one or more future transmissions in compliance with an RF exposure limit. The method further includes obtaining a size of a payload for a potential transmission. The method further includes determining transmission information based at least in part on the RF exposure budget and the size of the payload. The method further includes outputting the transmission information for a user of the wireless device.

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: Various aspects of the present disclosure generally relate to wireless communication. A user equipment (UE) may configure a first initial set of maximum transmit powers for a first subscriber module. The UE may configure a second initial set of maximum transmit powers for a second subscriber module. The UE may configure a first maximum transmit power associated with a first connection for the first subscriber module. The UE may configure, independently of the configuration of the first maximum transmit power, a second maximum transmit power associated with the second connection. The UE may transmit based at least in part on at least one of the first maximum transmit power or the second maximum transmit power. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an apparatus may determine a time-averaged power limit of a set of antennas. The apparatus may modify an antenna switching configuration based at least in part on the time-averaged power limit. The apparatus may transmit a signal using an antenna, from the set of antennas, associated with the modified antenna switching configuration, wherein the antenna is associated with a higher power limit than one or more other antennas. Numerous other aspects are described.

Abstract: Techniques and apparatus for operating a wireless device pursuant to RF exposure compliance are provided. An example method generally includes: when an RFECS1 of the wireless device is in an online state, controlling, via the RFECS1, at least one of one or more first radios associated with a first RAT or one or more second radios associated with a second RAT, in compliance with an RF exposure limit and based on at least one of first RF exposure information associated with the one or more first radios or second RF exposure information associated with the one or more second radios; and when the RFECS1 is unavailable, controlling, via a second RF exposure control scheme, the one or more second radios associated with the second RAT in compliance with the RF exposure limit and based on third RF exposure information associated with the one or more second radios.
