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

摘要

The present invention provides an apparatus and method of a mobile station transmitting power information in a multiple component carrier system. This specification discloses configuring a Type Indicator Field (TIF) to indicate whether a first type of a maximum transmission power and a second type of a maximum transmission power which are outputted for primary component carriers of a Primary Serving Cell (PSC) are identical with each other, configuring at least one power field on the basis of the TIF, and transmitting a Medium Access Control (MAC) message, including the TIF and the at least one power field, to a base station. According to the present invention, in a wireless system in which a component aggregation is used, a maximum transmission power report regarding a PSC within an MAC control element is not redundantly performed using a TIF. Accordingly, there is an advantage in that a waste of uplink resources can be reduced.
