Abstract
Provided are a method and apparatus for reporting power headroom in a mobile communication system supporting carrier aggregation. A user equipment (UE) determines the maximum transmit power for each carrier and the maximum UE transmit power, and sends a power headroom report that contains power headroom for each carrier computed based on the maximum transmit power for the carrier and the maximum UE transmit power to a corresponding base station (ENB).
