Transmitting power headroom reports about avaialble power levels in a node in an E-UMTS or LTE system

摘要

Disclosed is system for effectively transmitting a power headroom report (PHR) from the terminal to the base station in an evolved universal mobile telecommunications system (E-UMTS) evolved from universal mobile telecommunications system (UMTS) or a long term evolution (LTE) system. In particular, a method is disclosed of providing the power headroom report after determinations of whether the power headroom reporting is triggered and whether allocated uplink resource(s) accommodate a medium access control (MAC) control element.
