Beam-specific mpe reporting

An apparatus for wireless communication of a user equipment (UE), comprising:

• a memory;
• and
• at least one processor coupled to the memory and configured to:
• detect at least one maximum permissible exposure (MPE) event for at least one of one or more uplink beams, one or more downlink beams, or one or more UE panels;
• configure, upon detecting the MPE event, a power headroom report (PHR) including at least one of an MPE value, at least one beam identifier (ID), or at least one panel ID, the MPE value being associated with the MPE event, the at least one beam ID corresponding to the one or more uplink beams or the one or more downlink beams and the at least one panel ID corresponding to the one or more UE panels;
• and
• transmit, to a base station, the PHR including at least one of the MPE value, the at least one beam ID, or the at least one panel ID.

An apparatus for wireless communication of a base station, comprising:

• a memory;
• and
• at least one processor coupled to the memory and configured to:
• transmit, to a user equipment (UE), one or more downlink beams or receiving, from the UE, one or more uplink beams;
• and
• receive, from the UE, a power headroom report (PHR) including at least one of a maximum permissible exposure (MPE) value, at least one beam identifier (ID), or at least one panel ID, the MPE value being associated with an MPE event, the at least one beam ID corresponding to the one or more uplink beams or the one or more downlink beams and the at least one panel ID corresponding to one or more UE panels.
