Abstract: The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). According to embodiments, a method performed by a distributed unit (DU), the method comprises generating a control plane (C-plane) message for multiple ports, the C-plane message including section information and a section extension; and transmitting the C-plane message to a radio unit (RU) via a specific port of the multiple ports. The section information includes information on a beam identifier (ID). The section extension includes beam group type information for indicating a type of beam grouping, and port information for indicating a total number of one or more extended antenna-carrier (eAxC) ports indicated by the section extension.

Abstract: The disclosure relates to a pre 5th generation (5G) or 5G communication system to be provided for supporting higher data rates beyond 4th generation (4G) communication system such as long term evolution (LTE). A method for operating a radio unit (RU) of a base station is provided. The method includes transmitting, to a digital unit (DU), a first message comprising a value indicating the maximum number of masks for one resource area, and receiving, from the DU, a second message generated based on the value, wherein the mask may indicate resources to which the same beam is applied within the resource area.
