METHOD AND DEVICE FOR TRANSMITTING/RECEIVING CHANNEL STATE INFORMATION IN A WIRELESS COMMUNICATION SYSTEM

摘要

The present invention relates to a wireless communication system, and more particularly, to a method and device for transmitting/receiving channel state information (CSI). A method for a terminal for transmitting CSI according to one embodiment of the present invention includes: a first step of receiving a reference signal for channel measurement from a base station; a second step of generating sub-band (SB) CSI for each of a plurality of SBs using the received reference signal in the terminal and sequentially transmitting the generated SB CSI to a base station; and a third step of sequentially transmitting each SB CSI to a base station according to an order different from that of the sequential transmission.
