METHOD FOR COMMUNICATING WITH RELAY STATION
First Claim
1. A method for communicating with a relay station, in which a base station allocates a resource of a relay to perform communication, the method comprising:
- transmitting resource allocation information of downlink traffic and uplink traffic from the base station to the relay; and
transmitting the downlink traffic to the relay by encapsulating the downlink traffic in accordance with the resource allocation information and receiving encapsulated uplink traffic from the relay in accordance with the resource allocation information.

Abstract
A method for communicating with a relay station is disclosed. The method for communicating with a relay station comprises transmitting resource allocation information of downlink traffic and uplink traffic from a base station to the relay; and transmitting the downlink traffic to the relay by encapsulating the downlink traffic in accordance with the resource allocation information and receiving encapsulated uplink traffic from the relay in accordance with the resource allocation information. It is possible to enable efficient communication through a relay using a minimum interface without deterioration of throughput even in the case that a base station does not know detailed attributes of a relay existing in a system. Also, it is possible to coordinate collision through a master relay in case of a system supporting multi-hop relays.
