    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.

    Abstract: A method for transmitting signals by a first device of a base station transmitting and receiving signals of a wireless communication system is provided. The method includes receiving a plurality of uplink signals, identifying uplink transmission shaping information to be applied to the plurality of uplink signals, and transmitting the plurality of uplink signals to a second device by applying the uplink transmission shaping. The uplink transmission shaping information is information indicating for how many time intervals the first device is to transmit the plurality of uplink signals to the second device using a fronthaul. If the plurality of uplink signals are received by the first device for a first time, the plurality of uplink signals to which the uplink transmission shaping is applied are transmitted by the first device to the second device for the first time and a time determined based on the uplink transmission shaping information.

    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.
