APPARATUS AND METHOD FOR TRANSMITTING POWER INFORMATION IN MULTIPLE COMPONENT CARRIER SYSTEM

摘要

An apparatus and a method for transmitting power information by a mobile station in a multiple component carrier system includes: obtaining power headroom that is a difference between maximum transmit power of a mobile station for each component carrier and power estimated for actual uplink transmission; configuring an identification field that identifies a component carrier that the power headroom is for; configuring power headroom fields that indicates a level of power headroom; and generating a medium access control protocol data unit (MAC PDU) including the identification field and the power headroom field and transmitting the generated MAC PDU to a base station.
