Patent ID: 8238299

Claim:
A method for scheduling in a cellular system using a relay station (RS), the method comprising the steps of: classifying each of a plurality mobile stations (MSs) in a corresponding cell based on a base station (BS) into one of a Cooperative Transmission (CT) MSs for cooperative transmission and a Single Transmission (ST) MSs for single transmission according to each channel by signal-to-interference-plus-noise ratio (SINR) values of the MSs; mapping the CT MSs and ST MSs classified according to each channel to a channel capacity of each channel, which has been allocated to each RS, selecting a channel with a largest channel capacity, comparing the channel capacity of the selected channel with preset CT criteria, and transmitting, by a corresponding MS, a single request message or multiple request messages to the RS through a corresponding channel according to a result of the comparison; selecting an MS having a metric value of a highest priority according to a corresponding scheduling algorithm from among multiple MSs which have transmitted the request message(s), and transmitting a grant message to the selected MS; and accepting a channel of a corresponding scheduler which has transmitted the grant message.
