Title:
DEVICE AND METHOD FOR FRONTHAUL TRANSMISSION IN WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/060191
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 embodiments of the present disclosure, a method performed by a digital unit (DU) in a wireless communication system comprises the processes for: generating a control plane message including terminal scheduling information; and transmitting the control plane message to a radio unit (RU), wherein the control plane message comprises section extension information for antenna mapping in uplink (UL) beamforming-based terminal channel information, and the section extension information may include bit masking information for indicating whether or not antennas are to be combined.
