Patent ID: 8824355

Claim:
A mobile communication system comprising: a base station including a transmitter that provides wireless coverage in a cell, said cell being divided into a center region and a boundary region, said center region being surrounded by said boundary region, an outer edge of said boundary region defining an outer edge of said cell, said transmitter transmitting using first wireless resources allocated to the center region and second wireless resources allocated to the boundary region; and a relay node, wherein said relay node is configured to relay signals between said base station and a mobile station, said relay node including controller circuitry configure to operate the relay node in a selected relay mode chosen from a plurality of relay modes based on position information of the mobile station and position information of the relay node relative to the boundary region and the center region, each of the plurality of relay modes specifying predetermined wireless resource assignments for communications between the base station and the relay node, and between the relay node and the mobile station, a first relay mode of the plurality of relay modes specifying combined time division and frequency division multiple wireless resource access in which each of an uplink channel and a downlink channel employ mutually exclusive frequency bands, and a second relay mode and a third relay mode of the plurality of relay modes employ mutually exclusive frequency bands.
