<p>The present invention relates to a method for alignment of a first node (1) with at least one secondary node (2, 3) in a wireless communication network (4). The first node (1) is have first node antenna beams (5, 6, 7, 8, 9, 10) with corresponding designated pointing angles (11, 12, 13, 14, 15, 16). For each such beam, (5, 6, 7, 8, 9, 10) the method comprises the steps of, for each secondary node (2, 3): (29) directing a first node antenna beam (5, 6, 7, 8, 9, 10) in its designated pointing angle; (30) using a secondary node antenna beam (17a, 17b, 17c) where objects (18, 19, 20) can generate signal reflections/diffractions (21, 22, 23); and (31) detecting at least one signal property of reflected/diffracted signals (21, 22, 23). The method further comprises the steps: (32) exchanging information between the nodes (1, 2, 3), regarding beam angles (11, 12, 13, 14, 15, 16; 24, 25, 26) resulting in said signal property exceeding a corresponding threshold level; and (33) selecting a first node beam angle (11, 12, 13, 14, 15, 16) and a secondary node beam angle (24, 25, 26) from the these beam angles (11, 12, 13, 14, 15, 16, 24, 25, 26) for communication between the first node (1) and each secondary node (2, 3).</p> |
