    Abstract: Disclosed are a method and an apparatus for configuring a path in a communication system including an Xhaul network. A method for changing a path, performed by a first XDU, may comprise receiving from the XCU a path setup request message requesting to change a first path between the second XDU and the third XDU to a second path between the first XDU and the third XDU; receiving an SN status transfer message including an SN of data for the third XDU from the second XDU belonging to the first path, when the path setup request message is received; receiving from the second XDU the data corresponding to the SN indicated by the SN status transfer message; configuring the second path with the third XDU; and transmitting the data received from the second XDU to the third XDU through the second path.

    Abstract: Provided is a maritime communication system and method. A ship station of the maritime communication system may receive, from a maritime broadcast base station, maritime configuration information that includes setting information of shore base stations and setting information of maritime ship stations, may establish a radio link when a radio link configurable shore base station is present, may set the radio link through a radio link configurable neighbor ship station when the radio link configurable shore base station is absent, and may establish the radio link with an internal maritime satellite (INMARSAT) or a maritime very small aperture terminal (MVSAT) when the radio link configurable shore base station is absent and when the radio link configurable neighbor ship station is absent.

    Abstract: An operation method of a terminal may comprise receiving, from a base station, information of target transmission points targeted for a report of first channel state information (CSI) among the plurality of transmission points; receiving a first CSI-reference signal (CSI-RS) from the target transmission points; transmitting the first CSI determined based on the first CSI-RS to the base station; receiving, from the base station, information on a first transmission point determined based on the first CSI; receiving, from the first transmission point indicated by the information on the first transmission point, a second CSI-RS; receiving, from the base station, information on a requirement; and transmitting, to the base station, a second CSI including a transmission parameter for achieving the requirement.
