Abstract: A wireless relay device relays data from a transmitting device to a receiving device by wireless communication. The wireless relay device includes a buffer and a buffer control unit. The buffer temporarily stores relay target data. The buffer control unit controls the buffer, based on comparison of priority of first data received from the transmitting device with priority of second data stored in the buffer, (i) to remove the second data from the buffer and to store the first data in the buffer or (ii) not to store the first data in the buffer.

Abstract: A mobile communication system includes a base station and a mobile station. The base station receives a report on a channel state from the mobile station. The base station includes a receiving unit and a sending unit. The receiving unit receives a trigger for the report on the channel state sent from the mobile station. The sending unit sends allocation information on the radio resource used for the report on the channel state. The mobile station reports the channel state to the base station. The mobile station includes a sending unit and a receiving unit. The sending unit sends a trigger for a report on the channel state. The receiving unit receives the allocation information. The sending unit sends information on the channel state based on the allocation information.
