    Abstract: A D2D (Device-to-Device) discovery method is provided which enables a first terminal within a first cell to discover a second terminal within a second cell without relay of a base station. The first terminal receives, from a first base station of the first cell, information about a first resource for D2D discovery through a SIB (System Information Block) or RRC (Radio Resource Control) message. The first terminal transmits a D2D discovery signal using the first resource.

    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: Upon receiving a multicast packet from a base station, a forwarding terminal connected to the base station establishes a multicast connection with at least one direct communication terminal having a direct communication group identifier mapped to a multicast IP address of the multicast packet, and transmits the multicast packet to the at least one direct communication terminal, thereby providing multicast services to a direct communication terminal not connected to the base station.

    Abstract: A mobile relay station (RS) and a handover method thereof are provided. When it is determined that a mobile RS performs handover from a superordinate base station (BS) to a target BS, information indicating admission of handover is received from the superordinate BS. The mobile RS transmits a service unavailability section to a subordinate terminal, whereby the subordinate terminal is prevented from performing handover to a different BS or a different RS.

    Abstract translation: 提供了一种移动中继站（RS）及其切换方法。 当确定移动RS执行从上级基站（BS）到目标BS的切换时，从上级BS接收到指示接纳切换的信息。 移动RS将服务不可用部分发送到下级终端，由此防止下级终端对不同的BS或不同的RS进行切换。
