DEVICE AND METHOD FOR PERFORMING FULL-DUPLEX BASED COMMUNICATION IN UNLICENSED BAND IN WIRELESS COMMUNICATION SYSTEM

Title:

DEVICE AND METHOD FOR PERFORMING FULL-DUPLEX BASED COMMUNICATION IN UNLICENSED BAND IN WIRELESS COMMUNICATION SYSTEM

Document Type and Number:

WIPO Patent Application WO/2024/063604

Kind Code:

A1

Abstract:

The objective of the present disclosure is to perform full-duplex based communication in an unlicensed band in a wireless communication system. This operating method of a base station may comprise the steps of: transmitting system information including information related to a communication band; transmitting, in the communication band, configuration information related to the division of an uplink resource and a downlink resource; performing, on the basis of the system information and/or the configuration information, a first channel access procedure (CAP) for a first channel and a second channel included in the communication band; transmitting a signal on the first channel on the basis that the first CAP is successful on the first channel; and performing a second CAP on the second channel while the signal is transmitted on the first channel.
