Abstract
An apparatus and method for transmitting a power headroom report in a communication system supporting multi-carriers are disclosed, by which a user equipment is enabled to transmit the power headroom report. According to the present invention, a user equipment calculates a power headroom for each of at least one activated serving cell using a maximum transmission power of the user equipment for each of at least one activated serving cell and transmits the power headroom report including the power headroom for each of the at least one activated serving cell and the maximum transmission power of the user equipment for each of the at least one activated serving cell to a base station. In this case, the power headroom includes an information on power status of the user equipment for each of the at least one activated serving cell.
