摘要： The present invention relates to a wireless communication system, and more specifically, disclosed are a method and an apparatus for transmitting channel state information in a cooperative multipoint communication system. A method for a terminal transmitting the channel state information (CSI) with respect to multiple base stations in a wireless communication system, according to one embodiment of the present invention, comprises the steps of: receiving information on a periodic report setting of CSI including a rank indicator (RI) with respect to a first base station and a first type of precoding matrix indicator (PMI), and information on a periodic report setting of CSI including an RI with respect to a second base station and the first type of precoding matrix; and a step of transmitting the CSI to the first base station and the second base station on the basis of CSI report setting with respect to the first base station and the second base station, wherein a report on one of the first type of PMI with respect to the first base station, the first type of PMI with respect to the second base station, and the RI with respect to the second base station is omitted, and additional CSI can be transmitted when the report is omitted.
