Method and a device for determining if an information word transferred by at least a source has to be relayed

A decoding device for determining if an information word transferred by at least a source in a wireless cellular telecommunication network has to be relayed by a telecommunication device, signals transferred by the source being composed of complex symbols obtained from the information word, the decoding device for determining if the information word has to be relayed included in the telecommunication device, the decoding device comprising:

• means for receiving at least one signal composed of complex symbols transferred by at least the source;
• means for successfully decoding the information word from the at least one received signal composed of complex symbols;
• means for checking if the successful decoding of the information word is completed 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;
• means for obtaining at least one signal composed of complex symbols obtained from the information word if the successful decoding is performed prior to the expected successful decoding time of the information word;
• and
• means for transferring the at least one obtained signal if the successful decoding of the information word is completed prior to the expected successful decoding time of the information word.
