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.

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.

Abstract: Certain aspects of the present disclosure provide techniques and apparatus for exceptions to region-specific radio frequency parameters. An example method of wireless communication includes identifying a region in which the wireless device is located. The method further includes identifying an indication, associated with the identified region, of whether to apply one or more exception values or one or more default values, associated with one or more parameters for radio frequency (RF) exposure compliance. The method also includes selecting the one or more exception values based on the indication and transmitting a signal at a transmit power based at least in part on the selected one or more exception values.
