Title: METHOD FOR TRANSMITTING CHANNEL STATE INFORMATION IN WIRELESS COMMUNICATION SYSTEM, AND APPARATUS THEREFOR
Abstract:
The present invention provides a method for transmitting channel state information in a wireless communication system, and an apparatus therefor. Specifically, a method for transmitting, by a terminal, channel state information (CSI) in a wireless communication system supporting a short transmission time interval (TTI) may comprise the steps of: transmitting first CSI associated with a downlink channel received from a base station, to the base station in a first TTI; and transmitting second CSI associated with the received downlink channel, to the base station in a second TTI, wherein the first CSI includes information indicating a specific region including one or more indices associated with the CSI, and the second CSI includes information indicating a specific index which corresponds to a channel state associated with the received downlink channel among the one or more indices.
