Title:
METHOD FOR UPLINK TRANSMISSION IN WIRELESS COMMUNICATION SYSTEM, AND DEVICE THEREFOR
Document Type and Number:
WIPO Patent Application WO/2018/038418
Kind Code:
A1
Abstract:
According to one embodiment of the present invention, a method by which a terminal configured to have two or more processing times transmits a hybrid automatic repeat request-acknowledgment (HARQ-ACK) in a wireless communication system comprises the steps of: receiving, from a base station, a downlink control channel for indicating a downlink data channel, and the downlink data channel in one or more downlink subframes; and transmitting, to the base station, HARQ-ACK information on the downlink data channel in an uplink subframe corresponding to the one or more downlink subframes, wherein the HARQ-ACK information transmitted in the uplink subframe includes HARQ-ACK information on a downlink data channel in accordance with only one processing time among the two or more processing times, and cannot include HARQ-ACK information on a downlink data channel in accordance with the rest processing times.
