    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.

    Abstract: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for reporting CSI in a wireless communication system, the method comprising: a step for configuring a plurality of serving cells; and a step for reporting the CSI of only one serving cell in a corresponding subframe, wherein the step for reporting the CSI of only one serving cell comprises: excluding reporting the CSI of a lower priority when CSI reports of the plurality of serving cells in the corresponding subframe collide; and excluding reporting the CSI of serving cells other than the serving cell having the smallest index when the CSI reports of different serving cells having the same priority in the corresponding subframe collide.

    Abstract: A method of transmitting, by a terminal, a phase noise compensation reference signal in a wireless communication system is discussed. The method includes determining a frequency resource and a time resource of a demodulation reference signal (DM-RS); mapping the phase noise compensation reference signal to a frequency resource and a time resource based on the determined frequency resource and the time resource of the DM-RS; and transmitting, to a base station, the phase noise compensation reference signal on the mapped frequency resource and the time resource of the phase compensation reference signal. Further, a location of a phase noise compensation reference signal symbol in the time resource is determined based on a location of a DM-RS symbol in the time resource of the DM-RS.
