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.

1. A method for transmitting channel state information (CSI) in a terminal, the method comprising:
receiving a first reference signal for channel measurement from a base station; generating sub-band (SB) CSI for each of a plurality of SBs using the received first reference signal in the terminal, the plurality of SBs including a first SB and a second SB; transmitting the generated SB CSI to the base station sequentially according to a first SB order; and transmitting the generated SB CSI to the base station sequentially according to a second SB order different from the first SB order, wherein an average SB CSI transmission latency for the first SB according to the first SB order and the second SB order is equivalent to an average SB CSI transmission latency for the second SB according to the first SB order and the second SB order.
