1. A method of a distributed unit (DU) of a base station, the method comprising:
determining scheduling-related parameters for users by identifying one or more user equipment identifiers (ueIDs) corresponding to each of the users and a number of ueIDs corresponding to each of the users; and
transmitting, to a radio unit (RU), scheduling information including the scheduling-related parameters,
wherein the scheduling information comprises:
a first section extension field comprising information relating to the one or more ueIDs corresponding to each of the users, and
a second section extension field comprising information relating to the number of ueIDs corresponding to each of the users, and
wherein, for each of the users, the first section extension field comprises same ueID repeated as many times as the number of layers of each of the users.
