Title:
UPLINK SIGNAL TRANSMISSION OR RECEPTION METHOD FOR TERMINAL SUPPORTING PLURALITY OF TRANSMISSION TIME INTERVALS, PLURALITY OF SUB-CARRIER INTERVALS, OR PLURALITY OF PROCESSING TIMES IN WIRELESS COMMUNICATION SYSTEM, AND DEVICE THEREFOR
Document Type and Number:
WIPO Patent Application WO/2018/174450
Kind Code:
A1
Abstract:
Provided is a scheduling request (SR) transmission method for a terminal supporting a plurality of transmission time interval (TTI) lengths in a wireless communication system, according to one embodiment of the present invention, the method being performed by the terminal and comprising the steps of: receiving downlink data; and transmitting hybrid automatic retransmission request-acknowledgement (HARQ-ACK) in a first physical uplink control channel (PUCCH) when transmission time points of the first PUCCH of a first TTI length for transmitting HARQ-ACK/non-acknowledgement (NACK) corresponding to the downlink data and a second PUCCH for transmitting an SR transmission overlap, wherein the first PUCCH includes a smaller number of symbols than the second PUCCH, and the SR may not be transmitted when the first PUCCH does not include a valid SR resource.
