Method and apparatus for transmitting channel state information in frame structure of short transmission time interval

Abstract:

Provided are a method and an apparatus for transmitting, by a terminal, channel state information (CSI) in a frame structure of a short transmission time interval (sTTI). The method includes: receiving type information of a short transmission time interval from a base station through an RRC signaling; determining a channel state information transmission period of a short transmission time interval on the basis of the type information of the short transmission time interval; determining channel state information to be transmitted to the base station according to a channel state information transmission period of a general transmission time interval and the channel state information transmission period of the short transmission time interval; and transmitting the channel state information to be transmitted to the base station through an uplink control channel of a short transmission time interval, wherein the general transmission time interval is set to 12 or 14 symbols, and the short transmission time interval is set to 2, 4, or 7 symbols.
