Abstract

Various aspects of the disclosure relate to reporting power headroom of an apparatus such as a user equipment (UE). For an apparatus that uses beamforming, the power headroom associated with the beam the apparatus is using for wireless communication (e.g., with a base station) may be lower than the power headroom associated with another beam that the apparatus could use for the wireless communication. The disclosure relates in some aspects to using one beam for wireless communication and using the power headroom for another beam for a power headroom report. In this way, the apparatus may always report its full transmit power capability.
