Abstract: A handover procedure between transparent RSs(Relay Stations) in a multi-hop relay network is provided to enable a multi-hop MS(Mobile Station) to always use services by excluding a direct path between an MR-BS(Mobile Relay Base Station)/Anchor RS and an MS. An access RS transmits a MOB-RSHO-REQ message, or a handover request message, to an MR-BS/Anchor RS. In response to the MOB-RSHO-REQ message, the MR-BS/Anchor RS transmits a MOB-RSHO-RSP message to the access RS. The MR-BS/Anchor RS selects a target RS, and transmits a MOB-BSHO-ADD message, or a message which indicates service initiation for an MS, to the target RS. As the MR-BS/Anchor RS transmits a MOB-BSHO-DEL message, or a message which indicates service conclusion for the MS, to the access RS, the handover procedure is completed.

Abstract: PURPOSE: A method and an apparatus for obtaining synchronization between nodes, and a method for organizing multiple physical channels are provided to use physical channels as a common resource, thereby realizing collision avoidance and a collision solution algorithm with improved performance. CONSTITUTION: If power is applied to a type-2 node, a pulse generation unit(420) outputs a pulse at an output time of an initially effective peak waveform at each predetermined cycle in case of output of a preamble detection unit(410). A generated pulse row(403) and a self-running clock are provided as input of a PLL(Phase Locked Loop)(430). The PLL generates stable preamble transmission time. If output of the PLL is stabilized in the type-2 node, the type-2 node starts preamble transmission.
