Claim:
1. A method of reporting power headroom of a user equipment (UE), the method comprising: receiving simultaneous physical uplink control channel (PUCCH) and physical uplink shared channel (PUSCH) transmission information; generating first power headroom information and second power headroom information, wherein the second power headroom information is generated based on the simultaneous PUCCH and PUSCH transmission information; and transmitting a control message including the generated first power headroom information and the generated second power headroom information to a base station, wherein the first power headroom information is generated based on subtracting a first value associated with PUSCH transmit power from a second value associated with a maximum transmit power of the UE in a subframe, and the second power headroom information is generated based on subtracting a third value associated with the PUSCH transmit power and PUCCH transmit power from the second value associated with the maximum transmit power of the UE in the subframe.
