a first attenuation threshold dt 1 attenuation to the base station and a second attenuation threshold dt 2 attenuation to the destination terminal are defined step 81 if the attenuation between the terminal j and the base station is greater than the first threshold dt 1 arrow ko at the output of the test 82 the terminal j looks for potential relay nodes that may assist the transmission the terminal j transmits a rts on j packet containing its attenuation to the base station and control symbols step 83 the terminals of the cell which receive the rts on j packet estimate their channel gain toward the terminal j the corresponding attenuation together with their intercellular interference power received plus noise step 84 the base station transmits a cts j packet containing control symbols for each terminal j step 85 the terminals of the cell terminal j included receive the cts packet and estimate their channel gain to the base station and their intercellular interference power received plus noise step 86 for all the terminals i that have received the packet rts on j if the attenuation from a terminal i toward the terminal j is less than the second threshold dt 2 test 87 and if the attenuation of the same terminal i to the base station is lower than the attenuation of the terminal j to the base station test 88 this terminal becomes a potential relay step 89 the potential relay for the terminal j uplinks.
