    Abstract: A method performed by a radio unit (RU) may comprise: receiving a control plane (C-plane) message including section extension information from a distributed unit (DU) through a fronthaul interface; receiving a user plane (U-plane) message including remote interference management (RIM)-reference signal (RS) symbols from the DU through the fronthaul interface; and performing position adjustment for a cyclic prefix (CP) for the RIM-RS symbols and phase-difference compensation for the RIM-RS symbols. The section extension information may comprise at least one of indication information for indicating at least one of the RIM-RS symbols and compensation information related to the phase-difference compensation.

    Abstract: The present disclosure relates to a 5G or pre-5G communication system for supporting a higher data transfer rate than a 4G communication system such as LTE. The method is for phase correction of an antenna in a large-capacity antenna system, the method includes grouping large-capacity antennas into a predetermined number of groups; setting a path such that ports of the grouped antennas have a feedback path; outputting a test signal to be outputted to each antenna port of each group by adding a code or sequence having orthogonality; separating signals for each antenna port in the group by using the code or sequence having orthogonality in a signal received through the feedback path; and calculating a calibration value by detecting a phase change of the separated signal.

    Abstract: In various example embodiments, a method performed by a digital unit (DU) is provided. The method may comprise providing a radio unit (RU) with one or more reference signals for phase alignment. The one or more reference signals may be associated with one or more transmission paths of the RU. The method may comprise transmitting, to the radio unit (RU), a response signal control message for a response message. The method may comprise receiving, from the RU, the response message. The response message may include, for each transmission path of the one or more transmission paths of the RU, a path identifier (ID) and a response signal for a reference signal corresponding to the path ID.
