Abstract: PURPOSE: A communication device and a relay device are provided to select one of plural relay nodes and receive the signals of plural signal transmission nodes in the selected relay node in order to transmit coded signals after network coding to a signal reception node at one time, thereby increasing the frequency efficiency of a collaborative communication system. CONSTITUTION: A first signal reception unit(511) receives signals from plural signal transmission nodes(531-533), and a selection unit(512) selects one of relay nodes(521-523). A second signal reception unit(515) receives a network-coded signal from a selected relay node, and a decoding unit(516) detects the signals of plural signal transmission nodes after decoding based on the signal received by first and second signal reception units.

Abstract: A communication system for transmitting data with a collaborative communication relay is provided to enhance data transmission efficiency to a terminal from a relay by enabling the terminal to select the data received through a good wireless channel or combine the received data based on weight, which is assigned to the data received through the wireless channel. A receiver(210) receives a first preamble signal from a first relay, which is included in a first cluster consisting of a plurality of relays, and a second preamble signal from a second relay, which is included in a second cluster consisting of a plurality of relays. A controller(220) selects the cluster for connecting the first cluster to a base station based on the first and second preamble signal. A transmitter(230) transmits a connection request message to the first relay.
