Abstract
This disclosure provides systems, methods and apparatus for providing transmission power limit back-off for Specific Absorption Rate (SAR) compliance. In one aspect, a method implemented in a wireless communication apparatus is provided. The method includes receiving an indication of at least one operating mode indicative of a proximity and an orientation of at least one transmitting antenna of the wireless communication apparatus. The method further includes selecting from a plurality of transformations associated with the at least one operating mode. The method further includes applying a selected transformation to adjust a relationship between a power transmission level of a first transmitter and a power transmission level of a second transmitter. The method further includes determining a target power transmission level of the first transmitter based on the adjusted relationship and a current power transmission level of the second transmitter.
