Abstract
A relay device for relaying wireless communication between a transmission device and a reception device includes 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.
Claims5
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 transmitter 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.
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, by the relay device, to 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, by the relay device, the first data without storing the first data, when it is determined that a chance of retransmitting the first data is low;
- and
- requesting, by the relay device, 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.
