Abstract:
1. A method of adjusting at least transmission power or a transmission rate at a relay station for data communicated in a mobile communication system, wherein data is transmitted from a source station to a destination station over a first route and a second route, the method comprising: measuring a Signal to Noise Ratio (SNR) between the source station and relay station (SNR(S-R)); receiving, from the destination station, an SNR between the source station and the destination station (SNR(S-D)) and an SNR between the relay station and destination station (SNR(R-D)); generating an adjustment value of the at least the transmission power or the transmission rate by using the SNR(S-R), the SNR(S-D) and the SNR(R-D); and transmitting the adjustment value to the source station for adjusting the at least the transmission power or the transmission rate.
