Abstract: In a specific embodiment, our method of communicating a message between a transmitting station and a receiving station may be outlined as employing a hybrid automated retransmission request (HARQ) protocol in a multihop relay network. Our method includes the steps of, upon detecting transmission errors, obtaining a signal-to- interference and noise ratio (SINR) measurement at the physical layer (PHY) of the data transport framework from a forwarding Relay Station (RS2) by a Mobile Station wherein the estimates of the mean or standard deviation of the SINR measurement may be derived and updated. The derived values to be compared against a Bit Error Rate (BER) value as a channel quality threshold parameter, wherein channel quality is deemed good if the error function value is at least a BER threshold and normal HARQ encoding follows. Channel quality is deemed bad if the error function value is less than the BER threshold. Channel quality information is reported via at least one of a Channel Quality Information Channel (CQICH) or channel measure report response (REP-RSP) messaging. Transmission power control information is then encoded into a hybrid automated retransmission request (HARQ+) then transmitted.
