Title:
METHOD FOR TRANSMITTING/RECEIVING SPECIAL SUBFRAME IN WIRELESS COMMUNICATION SYSTEM AND DEVICE THEREFOR
Document Type and Number:
WIPO Patent Application WO/2018/143752
Kind Code:
A1
Abstract:
A method in which a terminal transmits/receives a special subframe in a wireless communication system supporting time division duplex (TDD) according to an embodiment of the present invention includes: a step for receiving information about a special subframe configuration; a step for receiving a downlink signal from a base station during a time corresponding to a downlink pilot time slot (DwPTS) allocated according to the special subframe configuration; and a step for transmitting an uplink signal to the base station during a time corresponding to an uplink pilot time slot (UpPTS) allocated according to the special subframe configuration, wherein the special subframe consists of the DwPTS, a guard period (GP), and the UpPTS, and is received or transmitted through an sTTI structure pattern including a plurality of short transmission time interval (sTTI) transmission blocks, wherein the sTTI structure patterns can be determined according to the special subframe configuration.
