キャリアアグリゲーションのための移動通信システムにおける使用可能送信電力情報を構成する方法及び装置

摘要

A method and apparatus for reporting Power Headroom (PH) of a User Equipment (UE) per carrier efficiently in a mobile communication system supporting carrier aggregation are provided. The method includes calculating PHs for multiple activated carriers based on whether data channel transmission takes place on each carrier, configuring indicators indicating whether the data channel transmission takes place on the corresponding carriers, and transmitting the PHs and indicators as aggregated in an extended PH Report (PHR) on one of the carriers.
