Pseudo-Omni-Directional Beamforming with Multiple Narrow-Band Beams
First Claim
1. A method for communication with a station on a wireless network, the method comprising:
- (a) forming a plurality of narrow-band beams, each having a different angular direction from an antenna of a base station, wherein the plurality of narrow-band beams are distributed over a beamspace to form a pseudo-omni-directional beam pattern;
(b) assigning each of the plurality of narrow-band beams to a different frequency band of the wireless network; and
(c) simultaneously broadcasting the plurality of narrow-band beams in a time varying manner such that the angular direction of each of the plurality of narrow-band beams varies with time.

Abstract
In a technique for communication with a station on a wireless network, the technique includes forming a plurality of narrow-band beams, each having a different angular direction from an antenna of a base station and collectively distributed over a beamspace to form a pseudo-omni-directional beam pattern. That beamspace may span an entire spherical region or a portion thereof, for example, when the narrow-band beams are broadcast over a sector of an entire spherical region. The technique may assign each of the plurality of narrow-band beams to a different frequency band (such as a different channel band or sub-channel) on the wireless network. The technique may simultaneously broadcast the plurality of narrow-band beams in a time-varying manner such that the angular direction of each of the plurality of narrow-band beams varies with time, where that variation may be random or ordered.
