Abstract
Methods and apparatus are provided for reporting a Power Headroom (PH) of a User Equipment (UE) in a wireless communication system having a plurality of aggregated uplink carriers. The PH is calculated for a Power Headroom Report (PHR)-triggered uplink carrier. A PHR having the PH and an identifier of the PHR-triggered uplink carrier is generated, and the PHR is transmitted to a network. Also, a PHR having the PH is generated, and the PHR is transmitted to a network over one of a plurality of PHR-transmitting uplink carriers configured to correspond to the PHR-triggered uplink carrier.
