The present invention concerns a method for determining if an information word transferred by a source has to be relayed by a telecommunication device. The signals transferred by the source are composed of complex symbols obtained from the information word. The telecommunication device: receives at least one signal composed of complex symbols transferred by at least the source, successfully decodes the information word from the at least one received signal composed of complex symbols, checks if the successful decoding is performed prior to an expected successful decoding time of the information word, the expected successful decoding time being obtained from prior successful decoding of other information words, and if the successful decoding is performed prior to the expected successful decoding time of the information word: obtains at least one signal composed of complex symbols obtained from the information word, transfers the at least one obtained signal.
