Abstract: PURPOSE: A relay communication method in a multi-terminal relay system is provided to execute relay communication through an optimal relay node. CONSTITUTION: A destination node determines an RD(Relay-Destination) channel level by allowing a relay node to overhear a signal transmitted by a source node(S330). The relay node transmits the R-D channel level to the source node(S340). The source node selects the relay nodes based on S-R(Source-Relay) channel information between the source node and the relay node and the R-D channel levels received from a plurality relay nodes(S350). The source node communicates with the destination node through the selected relay node(S370). [Reference numerals] (AA) Start; (BB) End; (S310) Source node transmits signals to relay nodes and a target node; (S320) Target node transmits ACK/NACK to the source node; (S330) Relay nodes overhear signals transmitted by the target node and estimates an R-D channel level; (S340) Relay nodes feedback R-D channel information; (S350) Source node selects a relay based on S-D channel information and the R-D channel information; (S360) Source node provides proactive scheduling information to the selected relay; (S370) Transmit data through the selected relay
