ABSTRACT:
In a transmission system having a procedure to exchange control information at least one time between a first terminal and a second terminal to transfer data from the first terminal to the second terminal, a relay station receives control information transmitted from the first terminal and detects existence of the control information from the second terminal during a preset detection time interval from a time of reception of the control information. If the control information has not been detected, the relay station exchanges the control information with said first terminal instead of the second terminal, receives data from the first terminal and transfers the data to the second terminal.
