Some embodiments include a processor that receive configuration information from a base station, and store based on the configuration information, a power control (PC) parameter set of a PC process that corresponds to a downlink (DL) reference signal (RS) or a beam-pair link (BPL), where the PC parameter set includes a path loss scaling factor, a command to perform a closed-loop PC process, or a path loss change parameter to be used to trigger a power headroom report (PHR). The processor can perform a PC procedure with respect to the DL RS or the BPL based on the PC parameter set, calculate a path loss estimate based on a downlink reference signal or the BPL, determine the PHR based on the path loss estimate and the path loss change parameter, calculate a power headroom value based on the PC parameter set, and transmit the PHR including the power headroom value.
