RELAY DEVICE AND WIRELESS RELAY METHOD
First Claim
1. A relay device for relaying wireless communication between a transmission device and a reception device, comprising:
- a buffer configured to temporarily store first data that is a relay object so that the first data is retransmitted to the reception device;
a buffer control unit configured to restrict the first data from being stored in the buffer when, based on information acquired using a signal fed back from the reception device, it is determined that a chance of retransmitting the first data is low; and
a retransmission request unit configured to request the transmission device to retransmit the first data when the first data is not stored in the buffer and the first data is to be retransmitted to the reception device.

4. A wireless relay method performed in a relay device for relaying wireless communication between a transmission device and a reception device, the wireless relay method comprising:
-
referring information acquired using a signal fed back from the reception device and determining a chance of retransmitting the first data, before first data that is a relay object is transmitted; transmitting the first data without storing the first data, when it is determined that a chance of retransmitting the first data is low; and requesting the transmission device to retransmit the first data when the first data is not stored and the first data is to be retransmitted to the reception device. - View Dependent Claims (5)
