Abstract:
1. A re-transmission control method for conducting wireless communication between a transmitting station and a receiving station via a relay station, the method comprising: a) transmitting data including control data and a plurality of data blocks from the transmitting station to the relay station; b) detecting whether there is an error in the plural data blocks at the relay station; c) updating the control data when an error is detected in at least one of the plural data blocks at the relay station; d) preventing an error-detected data block at the relay station from being transferred to the receiving station; e) transferring the updated control data and remaining data blocks from the relay station to the receiving station; f) generating a first negative response signal corresponding to the error-detected data block at the relay station; g) storing the first negative response signal at the relay station; h) detecting whether there is an error in the remaining data blocks transferred from the relay station at the receiving station; i) returning an affirmative response signal or a second negative response signal according to the detection results from the receiving station to the transmitting station; j) combining the first negative response signal with the affirmative response signal or the second negative response signal at the relay station; k) transmitting the combined response signal from the relay station to the transmitting station; and l) re-transmitting the error-detected data blocks corresponding to the first and second negative response signals from the transmitting station.
