Title:
METHOD AND DEVICE FOR TRANSMITTING/RECEIVING SIGNALS IN WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/030823
Kind Code:
A1
Abstract:
A method and a device for transmitting/receiving signals in wireless communication system, according to one embodiment of the present invention, comprise: transmitting a physical random access channel (PRACH); and receiving a random access response (RAR) on the basis of the PRACH. The PRACH may be transmitted after a type 2 uplink channel access procedure (CAP) is performed on the basis of the reception of downlink signals.
