METHOD AND APPARATUS FOR TRANSMITTING CHANNEL STATE INFORMATION IN FRAME STRUCTURE OF SHORT TRANSMISSION TIME INTERVAL

WIPO Patent Application WO/2018/056760

A1

The present disclosure relates to an operation of a terminal and a base station for transmission and reception of channel state information in a frame structure of a short transmission time interval of a 3GPP LTE/LTE-Advanced system. In an embodiment, 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 comprising the steps of: 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.
