APPARATUS AND METHOD FOR REPORTING POWER HEADROOM IN MULTIPLE COMPONENT CARRIER SYSTEM

摘要

Provided are an apparatus and a method for reporting power headroom by a mobile station in a multiple component carrier system. A method for reporting power headroom by a mobile station in a multiple component carrier system is disclosed. The method includes calculating power headroom values for at least one component carrier configured in the mobile station, receiving information regarding a recommended component carrier selected by a base station among the at least one component carrier configured in the mobile station, selecting at least one report component carrier used to report the calculated power headroom values based on the information regarding the recommended component carrier, and transmitting the calculated power headroom values to the base station through the at least one report component carrier.
