Title:
METHOD AND APPARATUS FOR PERFORMING COMMUNICATION IN WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/231096
Kind Code:
A1
Abstract:
A method and apparatus is provided in a wireless communication system supporting a shared spectrum channel access. According to an embodiment of the present disclosure, the method performed by a base station comprising receiving, from a user equipment (UE), physical uplink shared channel (PUSCH) transmission and in case that the BS shares the channel occupancy with the UE, transmitting, a downlink transmission after a gap from the PUSCH transmission, wherein the channel occupancy is initiated at the UE.
