Abstract:
The invention relates to a data packet transmission process in a communication system comprising at least one terminal (UE) communicating with a base station (BS), the process comprising at least one transmission (S4) of the data packet with a given power, from the terminal to the base station based on a HARQ scheme to obtain a residual packet error rate PERres after a number of transmissions Trn, the process being characterized in that it comprises a step (S) for the joint selection of the following parameters: the number of transmissions Trn; the target packet error rate PERtg(i) of each transmission i, where i=1, . . . , Trn, to arrive at the residual packet error rate PERres; and the modulation and coding scheme m corresponding to each target packet error rate PERtg(i) so as to minimize the data packet transmission power.
