1. A method for performing a transmission of data between a base station and a terminal, the terminal being included in a multi-hop network, the base station is able to communicate with entry points of the multi-hop network using beamforming, characterized in that the method includes:
obtaining, from the multi-hop network, for each entry point of the multi-hop network, a value of a first figure of merit representative of routing performance throughout the multi-hop network between said entry point of the multi-hop network and said terminal;
computing, independently of the values of the first figure of merit, a value of a second figure of merit representative of transmission performance between the base station and the multi-hop network, one value of the second figure of merit being computed for each candidate configuration among predefined candidate configurations of transmission between the base station and the entry points of the multi-hop network;
computing values of a third figure of merit combining values of the first figure of merit and of the second figure of merit, the third figure of merit being representative of a trade-off between routing performance throughout the multi-hop network and transmission performance between the base station and the multi-hop network;
selecting, for performing the transmission of data, a candidate configuration which shows the best value of the third figure of merit according to transmission performance between the base station and the terminal; and
performing the transmission of data via the selected entry point of the multi-hop network and by applying the selected candidate configuration.
