Time-averaged radio frequency (rf) exposure compliance across antenna grouping transitions

An apparatus for wireless communication, comprising:

• one or more memories collectively storing executable instructions;
• and
• one or more processors coupled to the one or more memories, the one or more processors being collectively configured to execute the executable instructions to cause the apparatus to:
• transition, during a run-time of the apparatus, from operating according to a first transmit scenario with a first set of antenna groups for a plurality of transmit antennas to operating according to a second transmit scenario with a second set of antenna groups, while maintaining compliance with a radio frequency (RF) exposure limit across the transition, wherein to transition to operating according to the second transmit scenario, the one or more processors are collectively configured to execute the executable instructions to cause the apparatus to determine the second set of antenna groups, such that an RF exposure history associated with the first set of antenna groups for the plurality of transmit antennas is maintained for the second set of antenna groups across the transition;
• and
• transmit, from at least one transmit antenna in the second set of antenna groups, while operating according to the second transmit scenario.
