ASYNCHRONOUS BIDIRECTIONAL COMMUNICATIONS IN CELL FREE NETWORKS
This abstract first appeared for US patent application 20250133511 titled 'ASYNCHRONOUS BIDIRECTIONAL COMMUNICATIONS IN CELL FREE NETWORKS
Original Abstract Submitted
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.
