Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may establish a first connection of a first radio access technology (RAT) associated with a first subscription of the UE. The UE may establish a second connection of a second RAT associated with the first subscription of the UE. The UE may establish a third connection of a third RAT associated with a second subscription of the UE. The UE may tune away from the first connection to receive a communication via the third connection. The UE may tune back to the first connection from the third connection. The UE may configure a transmission power parameter of the first connection based at least in part on a time-averaged parameter. Numerous other aspects are described.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may allocate a first amount of power to one or more radios for a time window based on radio frequency (RF) exposure information and one or more other criteria. The UE may allocate a second amount of power to a selected channel or communication utilized by at least one radio of the one or more radios for one or more time frames within the time window based on the first amount of power allocated to the at least one radio for the time window. The UE may transmit the selected channel or communication based on the first amount of power or the second amount of power. Numerous other aspects are described.

Allocation of transmit power in compliance with RF exposure requirements

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.

Techniques for power control for dual subscribers

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.

Configurable radio frequency exposure compliance based on region

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.

Exception-robust time-averaged radio frequency exposure compliance continuity

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.

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.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify, while camped on a first cell associated with a first radio access technology (RAT), a power management level for a communication using a second RAT, wherein the power management level indicates an available power for the communication using the second RAT, and wherein the available power is based at least in part on an exposure rate or an absorption rate. The UE may delay a transmission of a measurement report on the first cell based at least in part on the identification of the power management level. Numerous other aspects are provided.

Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may transmit a sounding reference signal (SRS) to a base station using an SRS antenna switch (SRS-AS) or an SRS carrier switch (SRS-CS) transmission technique and the UE may feature multiple antenna groups that have separate exposure budgets due to their spatial separation. The UE may employ one or more accounting procedures for tracking energy contributions associated with the SRS across the multiple antenna groups of the UE and may employ one or more power control procedures for setting a transmit power for an uplink signal in accordance with the energy contributions associated with the SRS.
