ANTENNA PANEL SELECTION FOR UPLINK TRANSMISSION UNDER A MAXIMUM PERMISSIBLE EXPOSURE (MPE) LIMIT

Abstract:

Aspects relate to beam management reports that enable selection of best antenna panel and beam combinations for uplink transmissions from a user equipment (UE) when one or more antenna panels of the UE are subject to a maximum permissible exposure (MPE) limit. The UE receives a reference signal at a plurality of antenna panels, wherein the reference signal is received in different beams on each of the plurality of antenna panels. The UE determines N beams providing highest measured strengths of the reference signal on at least one of the plurality of antenna panels, wherein the MPE limit is to be applied to the at least one of the plurality of antenna panels for uplink transmissions. The UE transmits a beam management report including reduced highest measured strengths of the reference signal in the N beams to account for the MPE limit.
