TECHNIQUES OF APPLICATION OF CLUSTERS OF ACCESS NODES DURING END-TO-END BEAM FORMATION Russian patent published in 2020 - IPC H04B7/185 

FIELD: physics.

SUBSTANCE: invention relates to end-to-end beam formation in a wireless communication system using access node clusters that differ from a user's coverage area. End-to-end beam formation of direct link may include multiple access nodes in one or more clusters of access nodes transmitting signals, which when relaying by multiple signals transmission / reception channels within the end-to-end repeater, form user beams in the user's coverage area. End-to-end beam formation of reverse link includes application of beam formation weight coefficients to signals transmitted by user terminals and relayed by multiple channels of signals transmission / reception in an end-to-end repeater to access nodes for generation of back-beam signals associated with reverse user beams. Clusters of access nodes may overlap or be outside the coverage area of user, and multiple clusters of access nodes may serve one or more coverage areas of user selectively or simultaneously. Plurality of frequency bands of the feeder link may be used by the same or different clusters of access nodes.

EFFECT: technical result is equalization of delays and elimination of distortions in feeder communication line.
