Patent ID: 8355357

Claim:
A method for operating a relay station in a wireless communication system using a multi-hop relay scheme, the method comprising receiving a request message requesting an admission control decision for a service flow from an upper node; determining whether a requested QoS parameter set included in the request message is supportable; if the requested QoS parameter set is supportable, forwarding the request message to a subordinate relay station corresponding to a next hop in a data transmission path without transmitting a response message to a base station; and if the requested QoS parameter set is unsupportable, transmitting a response message indicating the unsupportability of the requested QoS parameter set to the base station without forwarding the request message to the subordinate relay station corresponding to the next hop in the data transmission path, wherein the response message includes at least one of a Confirmation Code (CC) indicating the unsupportability of the requested QoS parameter set and a QoS parameter set which the relay station can support.
