Abstract:
A method for reporting power headroom value in a wireless access system that supports a carrier aggregation, and a user equipment (UE) for performing the method are discussed. The method according to one embodiment includes receiving a uplink transmission grant allocating uplink resources on a predetermined subframe in an anchor uplink component carrier (UL CC); obtaining power headroom value for the anchor UL CC, if the UE is configured with a simultaneous physical uplink control channel (PUCCH) and physical uplink shared channel (PUSCH) transmission; and reporting the power headroom value to a base station. The power headroom value is calculated.
