    Abstract: Certain aspects of the present disclosure provide techniques and apparatus for determining a transmit power based on a pattern and/or future conditions for a transmission while maintaining radio frequency (RF) exposure compliance. An example method generally includes obtaining a pattern associated with one or more first transmissions, determining a transmit power for one or more second transmissions based at least in part on the pattern and an RF exposure limit, and transmitting the one or more second transmissions at the determined transmit power.

    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: Embodiments described herein provide a method and apparatus for determining a maximum transmitter power for a mobile device. First, a maximum specific absorption rate (SAR) value is determined. Then, a maximum transmitter power based on the maximum SAR value is determined. The maximum SAR value may be determined using any or all of the following methods: using a composite worst-case SAR map, determining a usage position of the mobile device, and a running average of transmitter power. A further embodiment provides an apparatus for managing transmitter power. The apparatus includes a modem that is in communication with a transmitter; a processor in communication with the modem; and a memory in communication with the processor.

    Abstract: A self-test prediction system predicts the impact that a host device has on an embedded wireless device's receiver performance by recording the wireless device's received power. No carrier or pilot signal is necessary to predict the impact. The wireless device's embedded receiver monitors its own received power (e.g., RSSI) from any type of radiated noise from the host device. For receivers that do not provide RSS referenced to absolute power, an external reference tone can be used in order to scale the measured receiver carrier to noise or signal to noise data to an absolute power. The increase in measured received power on the wireless device's receiver correlates to the impact the host device will have on the embedded wireless device's receiver sensitivity performance, providing a faster approach with less external equipment than current approaches that use external equipment to simulate the wireless device's forward link signal.

    Abstract: Certain aspects of the present disclosure provide techniques and apparatus for operating a wireless communication device pursuant to radio frequency (RF) exposure across tissues and/or body locations. An example method of wireless communication by a user equipment generally includes determining a time-averaged RF exposure per exposure scenario or category. The RF exposure for the exposure scenario may be determined for a given antenna or group of antennas, where a grouping of the group of antennas may be specific to the exposure scenario or category. Another example method generally includes tracking sets of RF exposures separately across a plurality of locations associated with a human body over time, and transmitting a first signal at a first transmit power determined based on a time-averaged RF exposure limit and at least one of the tracked RF exposures.
