Abstract:
1. A base station comprising: a transmission timing determining unit determining a transmission timing of a data channel based on scheduling conducted upon a data transmission request from a mobile station; a transmission timing notifying unit notifying the mobile station of the determined transmission timing; a receiving unit receiving the data channel from the mobile station in accordance with the transmission timing; and a retransmission request notifying unit transmitting a retransmission request signal for the data channel to the mobile station, wherein when the base station has failed to decode the received data channel, the receiving unit waits to receive the data channel forwarded from a non-serving base station of the mobile station for a predefined time period, the data channel transmitted to the base station and the non-serving base station at the transmission timing determined based on the scheduling conducted upon the data transmission request from the mobile station, and if the receiving unit has not received the data channel from the non-serving base station for the predefined time period, the retransmission request notifying unit transmits the retransmission request signal to the mobile station.
