1. A method performed by a distributed unit (DU) of a base station in a wireless communication system, the method comprising:
transmitting, to a radio unit (RU) via a fronthaul interface, a management plane message for indicating that a regularization factor is transmitted in a section extension information,
wherein the section extension information is associated with a section type 5 for user equipment (UE) scheduling information, and is included in a control plane message, and
wherein the regularization factor is used for minimum means square error (MMSE) calculation of generating multi-user (MU) beamforming weight for UEs in a slot.
