METHOD FOR REPORTING CHANNEL STATE INFORMATION IN WIRELESS COMMUNICATION SYSTEM AND APPARATUS THEREFOR

摘要

The present application relates to a method for enabling a terminal to transmit channel state information in a wireless communication system. Specifically, the method for enabling the terminal to transmit the channel state information in the wireless communication system includes the steps of: receiving a reference signal from a serving cell or an adjacent cell; determining the priority of the predetermined Precoding Matrix Index (PMI) on the basis of the reference signal; and transmitting the PMI together with a stacking flag to the serving cell according to the priority, wherein the number of PMI to be transmitted to the serving cell is determined on the basis of a size of a buffer commonly set in the serving cell and the terminal, and the stacking flag indicates the storage of the PMI into the buffer or the initialization of the buffer.
