Abstract
A method performed by a distributed unit (DU) in a wireless communication system is provided. The method includes identifying a subblock in one section. The method includes generating a control plane (C-plane) message including section extension information including modulation compression information corresponding to the subblock. The method includes transmitting, to a radio unit (RU), the C-plane message through a fronthaul interface.
Claims22
A method performed by a distributed unit (DU), the method comprising;
- generating a control plane (C-plane) message including section information and section extension information for modulation compression;
