APPARATUS AND METHOD FOR CONTROLLING DATA RATE IN A COMMUNICATION SYSTEM USING MULTI-HOP SCHEME

摘要

A method for controlling a data rate by a Base Station (BS) in a multi-hop communication system in which a Relay Station (RS) located between the BS and a Mobile Station (MS) relays a signal exchanged between the BS and the MS. The data rate control method includes receiving, from the RS, channel information of the MS and channel information of the RS; calculating a target data rate to the RS using the channel information of the MS and the channel information of the RS; generating data to be transmitted to the RS according to the calculated target data rate; and transmitting the generated data to the RS.
