Abstract
A method to minimize a total transmit power in a bidirectional asynchronous cell free network where at least two transceivers, TRs, exchange their information using a number of amplify and forward, AF, based access points, APs, the total transmit power subject to quality of service, QoS constraints on TR data-rates, where the method includes estimating channels between the at least two TRs and the AF-based Aps. The method includes calculating a total power consumption for each channel tap. The method includes determining a single non-zero channel tap which results in a lowest total power consumption. The method includes, based on the single non-zero channel tap determined: calculating beamforming matrices for the APs; calculating a total power transmission of each transceiver of the at least two transceivers; calculating precoding matrices at each transceiver of the at least two transceivers; and calculating post-channel equalizers at the at least two transceivers.
