Abstract
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.
