Title:
METHOD FOR TRANSMITTING OR RECEIVING SIGNAL IN WIRELESS COMMUNICATION SYSTEM AND DEVICE THEREFOR
Document Type and Number:
WIPO Patent Application WO/2017/150855
Kind Code:
A1
Abstract:
According to one embodiment of the present invention, a method by which a terminal transmits a signal in a wireless communication system comprises the steps of: receiving timing advance (TA) information on a self-contained subframe having all of a downlink control region, a downlink data region, a guard period (GP) for transmission/reception switching, and an uplink control region; and transmitting uplink control information by advancing transmission timing corresponding to the uplink control region by the time length indicated by the TA information, wherein, when the time length indicated by the TA information is shorter than a predetermined magnitude, the terminal can first transmit a specific uplink signal, and then transmit the uplink control information in a GP remaining period remaining after completion of the transmission/reception switching.
