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.

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: 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: A permutated channel structure based on a block structure in talk-around direct communication is provided. A dedicated subchannel interferes with only one adjacent dedicated subchannel, even with a large synchronization error, by permutating the dedicated subchannels by cyclic shifts, whereby diversity gain can be maintained and interference between adjacent channels can be minimized.

Abstract translation: 提供了一种基于交谈直接通信中的块结构的排列通道结构。 即使具有大的同步误差，专用子信道也仅干扰一个相邻的专用子信道，通过循环移位排列专用子信道，从而可以保持分集增益，并且可以最小化相邻信道之间的干扰。
