Power headroom report procedure for a wireless network

Abstract:

Aspects of the disclosure relate to communication of power headroom reports in wireless communication networks. A user equipment (UE) may measure a path loss based on a triggering path loss reference signal (PL-RS) and trigger generation of a power headroom report (PHR) based on the path loss. The UE may identify uplink resources for communication of the PHR to a base station and determine whether the uplink resources are quasi-co-located with the triggering PL-RS. When the uplink resources are quasi-co-located with the triggering PL-RS, the user equipment may transmit the PHR utilizing the uplink resources. Otherwise, the UE may generate the PHR such that it includes information identifying the triggering PL-RS.
