Radio resource management technique for cellular systems using wireline relay stations

Control information: (Mobile Station MS) The invention wired relay station (RS:: Relay Station) the according to radio resource allocation method in a cellular system, a base station (BS Base Station) all the mobile terminals via the RS in the cell in the according to the quality of an process of collecting received feedback, and the channel status of each MS to dynamically assign the sub-channel with respect to the first process and a MS to belong to the divisions a group channel state preferred group of classifying into two groups: the performs a third step of dynamically allocating a subchannel to the second process, and considering, made to the MS that belongs to the classification of a group are not in good channel state resource group context-RS and the sub-channel channel gains. Relay Station, RS, the resource allocation, subchannel allocation
