Abstract: 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.

Abstract: 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.

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: 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: An apparatus including a housing; sensors configured to sense one or more locations upon which a user is gripping the housing; sensors including antenna modules configured to transmit a signal based on the one or more locations upon which the user is gripping the housing. Another aspect relates to an apparatus including a housing; a set of antenna modules situated proximate at different surface locations along the housing; and a controller configured to operate the set of antenna modules to determine at least one or more electromagnetic leakage coupling between at least one pair of antenna modules of the set. In this aspect, the controller may be configured to select one or more of the set of antenna modules for transmitting a signal based on the one or more electromagnetic leakage coupling associated with one or more of the different locations where a user grips the housing, respectively.

Abstract: Certain aspects of the present disclosure propose methods for determining power level of one or more transmitters based on a power level of a primary transmitter when the transmitters are located in close proximity of each other. The power levels may be determined such that a combined power of all the transmitters is compliant with regulatory radio frequency (RF) safety requirements. For certain aspects, power level of the lower priority transmitters may be determined utilizing one or more look-up tables. For another aspect, power level of the lower priority transmitters may be calculated using an algorithm based on the power level of the priority transmitter. In aspects, the power level of lower priority transmitters and the time duration for which the transmitters are active may be selected dynamically so that the time averaged power of the transmitters for a defined period of time falls below the RF exposure limit.
