Abstract: PURPOSE: A multi-channel/multi-interface mesh router and a method for fixed-distributed channel assignment are provided to assign channels while minimizing the interference in all mesh routers. CONSTITUTION: A neighbor information confirmation unit(112) transmits and receives hello message with neighboring mesh routers. The neighbor information confirmation unit acquires information of the mesh routers. A seed node confirmation unit(114) determines the priority of mesh routers through a neighbor information table. The seed node confirmation unit creates a PL(Parent List) and a DL(Dependent List). If the priority of the corresponding mesh router is highest one, a channel allocation unit(116) allocates the channel of the mesh routers within the cascade list.

Abstract: A method for selecting an RS(Relay Station) in a mobile communication system is provided to measure the signal quality of a signal transmitted from a UE(User Equipment) for an uplink slot time and select the RS on the basis of signal quality information included into an SS-SIG-REP message, thereby selecting the RS capable of providing the optimal service to each user out of plural RSs. A method for selecting a RS in a mobile communication system comprises the following steps of: performing network initialization when a UE enter a network initially(S100); transmitting a UL-MAP(Uplink-MAP) to the UE(S110); analyzing the UL-MAP allocated to the UE from a BS(Base Station) to recognize an uplink slot time(S120); measuring the signal quality of a signal transmitted from the UE for the uplink slot time and transmitting an SS-SIG-REP(Subscriber Station-Signal-Report) message including information about the measure signal quality to an upper RS collectively(S130); receiving the SS-SIG-REP message in the BS(S140); and selecting the RS for transceiving signals with the UE on the basis of the generated SS-SIG-REP message(S150).
