    • The present invention relates to a wireless communication system. More particularly, the present invention relates to a method and apparatus for transmitting channel quality information by a terminal. The method for transmitting channel quality information by a terminal in a wireless communication system that supports coordinated multipoint (CoMP) technology, comprises the steps of: receiving information on a plurality of transmission nodes capable of performing CoMP transmission; transmitting first channel state information on one or more preferred transmission nodes from among the plurality of transmission nodes; receiving pattern information consisting of a plurality of combinations of CoMP sets, each of which corresponds to a relevant time interval according to the pattern information; and performing an operation for transmitting second channel state information on the combination of CoMP sets corresponding to a subframe n. When the combination of CoMP sets corresponding to the subframe n is overlapped with said one or more preferred transmission nodes, the second channel state information is transmitted. When the combination of CoMP sets corresponding to the subframe n is not overlapped with said one or more preferred transmission nodes, the second channel state information is dropped.
    • 无线通信系统技术领域本发明涉及一种无线通信系统。 更具体地说,本发明涉及一种终端发送信道质量信息的方法和装置。 在支持协同多点(CoMP)技术的无线通信系统中由终端发送信道质量信息的方法包括以下步骤:在能够执行CoMP传输的多个传输节点上接收信息; 从所述多个传输节点中的一个或多个优选传输节点发送第一信道状态信息; 接收由CoMP集合的多个组合组成的模式信息,每个组合对应于根据模式信息的相关时间间隔; 并且对与子帧n对应的CoMP集的组合执行用于发送第二信道状态信息的操作。 当对应于子帧n的CoMP组的组合与所述一个或多个优选传输节点重叠时,发送第二信道状态信息。 当对应于子帧n的CoMP组合不与所述一个或多个优选传输节点重叠时,第二信道状态信息被丢弃。
