Abstract
Wireless communication is established between a first station and a second station in a wireless communication system, the first station having a beamforming network configured to form a succession of beams using antenna weight vectors selected from a pre-determined plurality of antenna weight vectors. The orientations of the beams are arranged in a grid comprising a plurality of rows. The beams of each row are spaced in angular position such that at least one beam in a respective row is positioned mid-way between the positions of two beams on an adjacent row. A succession of beams is formed to send first messages using a selected first sub-set of the antenna weight vectors. If a first message in a first beam is received at the second station, a further succession of beams is formed using a second sub-set of the antenna weight vectors selected to form beams adjacent to the first beam.
