Abstract:
1. A method for determining a configuration of a wireless telecommunications network, the configuration aiming at increasing a quality of signals received by at least one destination device among plural destination devices of the wireless telecommunications network, plural flows of complex modulation symbols being transmitted on a same resource by respective source devices of the wireless telecommunications network, the source devices being associated with respective destination devices, each source device transmitting at least one flow of complex modulation symbols on the same resource to its associated destination device, the method comprising: obtaining a first set of channel matrices representing transmission channels between the source devices and each destination device and a second set of channel matrices representing transmission channels between a relay device of the wireless telecommunications network and each destination device; selecting at least one flow of complex modulation symbols for which the relay device has to apply a pre-coding; and determining a pre-coding matrix aiming at being used by the relay device for applying the pre-coding to be able to transmit pre-coded complex modulation symbols, on the same resource as the complex modulation symbols transmitted by the source devices, to increase the quality of signals received by at least one destination device, the pre-coding matrix being determined on the basis of the first and second sets of channel matrices, of the selected at least one flow of complex modulation symbols, and of a transmission power constraint applicable to the relay device.
