    • The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for reporting channel state information, wherein the method comprises the steps of: receiving configuration information for a periodic report of CSI from a first transmission point; and transmitting, to said first transmission point, a CSI report for the downlink of a transmission point corresponding to a corresponding subframe among a plurality of transmission points through each subframe that is periodically set according to said configuration information, wherein: one or more subframes corresponding to a second transmission point are used to transmit a CSI report for multi-transmission point cooperative transmission, if rank information reported to said first transmission point prior to said CSI report is a critical value or less; and one or more subframes corresponding to said second transmission point are used to transmit a CSI report for single-transmission point transmission, if the rank information reported to said first transmission point prior to said CSI report is said critical value or more.
    • 本发明涉及一种无线通信系统。 更具体地,本发明涉及用于报告信道状态信息的方法和设备,其中该方法包括以下步骤:从第一传输点接收关于CSI的周期性报告的配置信息; 以及通过根据所述配置信息周期性设置的每个子帧向所述第一发送点发送针对与多个发送点之中的对应子帧相对应的发送点的下行链路的CSI报告,其中:一个或多个子帧对应于 如果在所述CSI报告之前向所述第一传输点报告的秩信息是临界值或更小,则将用于传输用于多传输点协作传输的CSI报告的第一传输点传输到第二传输点; 并且如果在所述CSI报告之前向所述第一传输点报告的秩信息是所述临界值或更多,则使用对应于所述第二传输点的一个或多个子帧来传输用于单传输点传输的CSI报告。
