Abstract: A resource management method performed by a CP in C-RAN system includes configuring M user-centric cells for M terminals with a plurality of ANs, and determining a number K of orthogonal resource sharing groups sharing a same orthogonal resource; selecting K user-centric cells as group headers for the K orthogonal resource sharing groups, and adding the selected K user-centric cells as group headers to the K orthogonal resource sharing groups; configuring the K orthogonal resource sharing groups by sequentially adding ungrouped user-centric cells to the K orthogonal resource sharing groups; and dividing total system resources into K orthogonal resources, and mapping the divided K orthogonal resources to the K orthogonal resource sharing groups, respectively.

Abstract: An operation method of a first communication node in a communication network, which supports a radio link control (RLC) function among functions of a base station, may comprise receiving a first message from a second communication node supporting a packet data convergence protocol (PDCP) function among the functions of the base station; processing the received first message by performing the RLC function; and transmitting the processed first message to a third communication node supporting a medium access control (MAC) function and physical (PHY) functions among the functions of the base station.

Abstract: An operation method of a first communication node, which controls a plurality of communication nodes included in a mobile xhaul network supporting mobility, may comprise performing an attach procedure between the first communication node and a second communication node among the plurality of communication nodes; configuring a path for communications between the second communication node and a third communication node for which attach procedure has been completed among the plurality of communication nodes; and supporting communications of the second communication node and the third communication node using the configured path.
