Title:
APPARATUS AND METHOD FOR SPECTRUM SHARING IN WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/256896
Kind Code:
A1
Abstract:
The present disclosure relates to a 5th generation (5G) or pre-5G communication system for supporting a higher data transmission rate than a 4th generation (4G) communication system such as long term evolution (LTE). According to various embodiments of the present disclosure, an apparatus operated by a distributed unit (DU) of a base station in a wireless communication system, comprises at least one transceiver and at least one processor. The at least one processor controls the at least one transceiver to transmit, via a DU interface, a message including information related to spectrum sharing to another node supporting a second cell that shares, with a first cell of the base station, a frequency band in a specified range. The information related to the spectrum sharing may include identification information regarding the first cell and identification information regarding the second cell.
