1. A primary station configured for transmitting and receiving communications comprising:
- a circuit for generating and shaping a plurality of beams in an array;
an antenna for transmitting and receiving communication signals within said beams;
a beam directing circuit for directing said beams;
whereby said beam directing circuit selectively directs at least one of the shaped beams at a plurality of directions; and
a signal identification circuit for sending an identifier to identify the shaped beam in accordance with at least a subset of said plurality of directions;
wherein said plurality of directions coincide with sectors of a cell, the cell sectors having different sizes and said shaping circuit shapes the beams to cover the cell sectors.

Abstract
A primary station for a wireless communication system transmits and receives communications within a sectorized cell with at least one secondary station. The primary station transmits and receives signals within a beam; and directs the signal transmission and reception as a shaped beam. The shaped beam is directed at a plurality of predetermined directions; either continuously or discretely.
