TERMINAL DEVICE FOR TRANSMITTING A POWER HEADROOM REPORT IN A MULTI-CARRIER COMMUNICATION SYSTEM, AND METHOD FOR SAME

摘要

Disclosed is a terminal device for transmitting a power headroom report (PHR) in a multi-carrier communication system, and a method for same. The terminal device for transmitting a power headroom report (PHR) in a multi-carrier communication system comprises a transmitter and a processor. The transmitter transmits, to a base station, a power headroom report for one or more active component carriers allocated to user equipment from among multiple carriers. The processor controls the transmitter such that the transmitter transmits the power headroom report including a first type of power headroom information calculated using the power value of a physical uplink shared channel (PUSCH) of the main component carrier among the active component carriers, and a second type of power headroom information calculated using the power value of the PUSCH and the power value of a physical uplink control channel (PUCCH) of the main component carrier.
