Abstract:
1. A wireless relay device that relays relay signals from a transmitting device to a receiving device by wireless communication, comprising: a retransmission buffer that temporarily stores a part of the relay signals to retransmit the part of the relay signals according to a retransmission request from the receiving device; and a buffer control unit that compares priority of a first relay signal received from the transmitting device and priority of a second relay signal stored in the retransmission buffer, and controls the buffer (i) to remove the second relay signal from the retransmission buffer and to store the first relay signal in the retransmission buffer in a condition that the priority of a first relay signal is higher than the second relay signal or (ii) not to store the first relay signal in the retransmission buffer in a condition that the priority of a first relay signal is lower than the second relay signal.
