Title:
METHOD AND APPARATUS FOR TRANSMITTING UPLINK CHANNEL IN WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/031152
Kind Code:
A1
Abstract:
The present invention relates to a method for transmitting an uplink channel in a wireless communication system. The method performed by a terminal comprises the steps of: receiving resource information related to transmission of an uplink channel from a base station; detecting a downlink channel transmitted from the base station; and transmitting the uplink channel to the base station on the basis of the resource information according to the result of detecting the downlink channel, wherein the uplink channel is transmitted within a channel-occupancy time (COT) initiated by the base station or transmitted within a COT initiated by the terminal.
