Terminal device, relay device, and base station communication method

A relay device that relays data between a base station and a terminal device, the relay device comprising:

• a data-receiving unit that receives data from the base station, the data including first control information that represents a first communication mode which is a mode of communication from the base station to the relay device;
• and
• a data-transmission unit that adds second control information to the data received by the data-receiving unit, the second control information representing a second communication mode which is a mode of communication from the relay device to the terminal device, and relays the data to the terminal device.

A relay device that receives data from a base station, the relay device comprising:

• a buffer that receives first data sent from the base station to the relay device in a first communication mode which is a mode of communication from the base station to the relay device and stores the received first data;
• and
• a data signal reception-processing unit that adds a second control information representing a second communication mode, which is a mode of communication from the relay device to the terminal device, to the first data sent from the base station to the relay device to form second data, performs reception processing on second data transmitted from the relay device to the terminal device based on the second control information included in the second transmitted data, performs reception processing on the received first data stored in the buffer based on the first control information included in the second data, and combines the second transmitted data subjected to the reception processing and the first received data subjected to the reception processing.

A base station that receives data from a terminal end and a relay device, the bases station comprising:

• a buffer that receives first data sent from the terminal end to the relay device in a first communication mode which is a mode of communication from the base station to the relay device and stores the received first data;
• and
• a data signal reception-processing unit that adds a second control information representing a second communication mode, which is a mode of communication from the relay device to the base station, to the first data sent from the terminal device to the relay device, performs reception processing on second data relayed from the relay device to the base station based on the second control information included in the second data, performs reception processing on the received first data stored in the buffer based on the first control information included in the second data, and combines the second data subjected to the reception processing and the received first data subjected to the reception processing.
