Abstract
In the hybrid automatic repeat request (H-ARQ) supporting method for cooperative transmission, a receiver selects one H-ARQ repeat method from among the chase combining method and the incremental redundancy method according to the SNR when the data packet cooperatively transmitted by transmitters generates an error. Also, the method for the receiver to select a repeat transmitter includes a method for selecting a repeat transmitter in advance, a method for removing a transmitting node from a repeat transmitter group when the SNR of the transmitting node is low, and a method for estimating the SNR of each transmitter for each predetermined time frame and selecting the transmitter having the greatest SNR as the repeat transmitter.
