    Abstract: The present invention relates to a channel quality information transmission method in a communication system adopting a coordinated multi-point scheme. A terminal receives signals, through the same band, from a serving base station and at least one neighbor base station, respectively, which are included in a CoMP set operating in a joint processing mode. Next, the terminal generates combined channel quality information on a single signal obtained by combining the signals received through the same band, and then transmits the information to the serving base station. The combined channel quality information is generated using information on a combined channel obtained by combining channels between the terminal and the serving base station and between the terminal and each one of the at least one neighbor base station, which are included in the CoMP set.

    Abstract: Provided are a method and apparatus for setting a frame of a relay station in a wireless communication system. A base station sets an access zone frame and a relay zone frame adjacent the access zone frame. The access zone frame comprises a downlink (DL) access zone in which the base station or the relay station transmits a signal to a terminal, and an uplink (UL) access zone in which the terminal transmits a signal to the base station or to the relay station. The relay zone frame comprises a DL relay zone in which the base station transmits a signal to the terminal or to the relay station, and a UL relay zone in which the terminal or the relay station transmits a signal to the base station.
