1. A first type node in a wireless communication system, the first type node is being configured to:
communicate with at least one other first type node in the wireless communication system over a corresponding channel by means of one of at least one type of signal relaying that employs decoding and encoding;
receive a plurality of signals, each signal being associated with a corresponding decoding error probability, from the other first type node;
estimate the decoding error probability for each signal;
sort the signals in a decoding order according to the estimated decoding error probability;
decode the signals one at the time from the lowest estimated decoding error probability to the highest estimated decoding error probability until decoding for a certain signal is determined to have failed;
request re-transmission of the signal for which decoding has been determined to have failed; and
request re-transmission of all signals having higher decoding error probability than the signal for which decoding has been determined to have failed.
