RELAY DEVICE, AND WIRELESS RELAY METHOD

PROBLEM TO BE SOLVED: To provide a relay device, along with a wireless relay method, capable of reducing capacity of a buffer for temporarily storing data of a relay object for retransmission, when wireless communication from a transmission device to a receiving device is relayed. SOLUTION: In a relay station, in relaying data to the mobile station, it is determined on the basis of feedback information of the mobile station whether the chance of retransmitting the data to the mobile station is high. For example, when, by referring to the feedback information, it turns out that the wireless quality between the relay station and the mobile station is favorable, it is assumed that wireless relay to the mobile station has a high success probability, thereby it is determined that the chance of retransmitting the data to the mobile station is low. Namely, the relay station determines that data is not to be stored in the retransmission buffer (Step S16). Accordingly, data accumulation in the retransmission buffer is suppressed.
