LOCAL COMMUNICATION BETWEEN MOBILE STATIONS VIA ONE OR MORE RELAY STATIONS
First Claim
1. A method for communicating between a first mobile station and a second mobile station in a radio communications system that includes a base station associated with a cell coverage area and one or more relay stations located in the cell, comprising:
- determining an association between each of the first and second mobile stations and one or more of the relay stations; and
based on the determined associations, selecting one or more of the relay stations to perform a radio communication between the first and second mobile stations without the radio communication passing through the base station.

Abstract
In a cellular communication system where two mobile stations are located within or near to a cell associated with a base station, one or more relay stations with good radio link quality relative to the two mobiles may be used to build a local forwarding communication link between the mobile stations using the one or more relay stations which avoids downlink/uplink transmission with the base station. The relay station(s) is(are) selected based on an association between two mobile stations and the relay station(s).

11. Apparatus for a relay station for communicating between a first mobile station and a second mobile station in a radio communications system that includes a base station associated with a cell coverage area and arranged to communicate with the relay station located in the cell, the relay station apparatus comprising:
-
radio circuitry transmitting and receiving signals over a radio interface; and a controller for determining an association between each of the first and second mobile stations and the relay station and to perform a radio communication using the radio circuitry between the first and second mobile stations without the radio communication passing through the base station. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)

20. Apparatus for a base station in a radio communications system where the base station is associated with a cell coverage area and is arranged to communicate with one or more relay stations located in the cell, the base station apparatus comprising:
-
radio circuitry transmitting and receiving signals over a radio interface; and a controller for determining an association between each of a first mobile station and a second mobile station and the one or more relay stations, determining one or more common relay station(s) based on the determined associations, and instructing the one or more common relay station(s) to perform a radio communication between the first and second mobile stations without the radio communication passing through the base station. - View Dependent Claims (21, 22, 23)
