    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: A method for a transmitter of a mobile communication system transmitting and receiving signals according to an embodiment of the present specification comprises the steps of transmitting to a receiver system information for transmitting a signal to the receiver including a connection between a wireless resource and a transmitting antenna; transmitting a reference signal to the receiver based on the system information; and receiving from the receiver feedback information generated based on the reference signal. According to an embodiment of the present specification, in a beamforming transmission method of a mobile communication system, a transmitter can determine whether to perform digital pre-coding without advance information from a receiver and can consequently perform a transmission, and can thereby perform lower-overhead and efficient signal transmission/reception.

    Abstract: The present disclosure relates to a 5th (5G) generation) or pre-5G communication system for supporting a higher data transmission rate beyond a 4th (4G) generation communication system such as long term evolution (LTE). An operating method of a base station in a wireless communication system according to various embodiments of the present disclosure includes generating at least one compressed symbol based on modulation compression, transmitting to another base station, control information including position indication information which indicates a position of a subcarrier at which a first subcarrier signal is transmitted in a physical resource block (PRB) to which the at least one compressed symbol is mapped, and power indication information for indicating a transmit power of the first subcarrier signal, and transmitting the at least one compressed symbol to the another base station. Thus, transmission capacity may be optimized, and efficient modulation compression is possible.
