<p>In a wireless relay system, a relay station RN compares the priority of data (first data) received from a base transceiver station BTS (transmitting device) with the priority of data (second data) stored in a buffer of the relay station RN. Based on the comparison result of the priorities of the data, the relay station RN removes the second data from the buffer and stores the first data in the buffer or does not store the first data in the buffer and transmits the first data to a mobile station UE (receiving device). Thus, the capacity of the buffer that temporarily stores relay target data can be reduced and communication delay of data with high priority scarcely occurs.</p> |
