A METHOD FOR ALIGNMENT OF MULTI-BEAM ANTENNAS IN A NON LINE-OF-SIGHT SCENARIO

摘要

The present invention relates to a method for alignment of a first node with at least one secondary node in a wireless communication network. The first node includes first node antenna beams with corresponding designated pointing angles. For each such beam, the method comprises the steps of, for each secondary node: directing a first node antenna beam in its designated pointing angle; using a secondary node antenna beam where objects can generate signal reflections/diffractions; and detecting at least one signal property of reflected/diffracted signals. The method further comprises the steps: exchanging information between the nodes, regarding beam angles resulting in said signal property exceeding a corresponding threshold level; and selecting a first node beam angle and a secondary node beam angle from the beam angles for communication between the first node and each secondary node.

1. A method for alignment of a first node with at least one secondary node in a wireless communication network, the first node being adapted to direct a plurality of first node antenna beams at corresponding designated first node antenna beam pointing direction angles, wherein for each desired first node antenna beam, the method comprises, for each secondary node:
directing a first node antenna beam in its designated pointing direction; using a secondary node antenna beam for scanning a volume with at least one object, said object being able to generate signal reflections and/or signal diffractions; and detecting at least one signal property of reflected signals and/or diffracted signals;wherein the method further comprises:
exchanging information between the nodes, said information comprising first node antenna beam pointing direction angles and secondary node antenna beam pointing direction angles resulting in said signal property exceeding a corresponding threshold level; and selecting a first node antenna beam pointing direction angle and selecting a secondary node antenna beam pointing direction angle from the antenna beam pointing direction angles comprised in said exchanged information for communication between the first node and each secondary node.
