1. A method performed by a distributed unit (DU) of a base station in a wireless communication system, the method comprising:
based on a capability of a radio unit (RU), transmitting, to the RU, a management plane message associated with a regularization factor in a section type 5 for user equipment (UE) scheduling information,
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.
