Title:
METHOD FOR TRANSMITTING AND RECEIVING DATA IN WIRELESS COMMUNICATION SYSTEM SUPPORTING SHORT TRANSMISSION TIME INTERVAL AND APPARATUS THEREFOR
Document Type and Number:
WIPO Patent Application WO/2018/030873
Kind Code:
A1
Abstract:
Disclosed are a method for transmitting and receiving data in a wireless communication system supporting a short transmission time interval (TTI) and an apparatus therefor. Specifically, the method may comprise the steps of: receiving a downlink control channel for which a first TTI is configured; and transmitting a specific uplink channel for which a second TTI is configured, on the basis of the received downlink control channel, wherein the first TTI and the second TTI are configured to have different lengths, the specific uplink channel is transmitted through a subframe after a specific processing time from the end point of a resource region allocated to the downlink control channel, and the specific processing time is set according to at least one of a first processing time for the downlink control channel and a second processing time for the specific uplink control channel.
