Method and system for improved beacon acquisition performance with time slot and antenna sector reuse
First Claim
1. A method implemented in a wireless multi-cell communication system including a plurality of cells and a plurality of base stations, wherein each cell has at least three cell sectors, the method comprising:
- (a) each base station broadcasting a beacon signal into two of the at least three cell sectors in a first time slot; and
(b) each base station broadcasting a beacon signal into the remaining cell sector(s) in a second time slot different from the first time slot.

Abstract
A wireless multi-cell communication system, such as a time division duplex (TDD) system, includes at least one wireless transmit/receive unit (WTRU) and a plurality of base stations which broadcast beacon signals into a plurality of sectors of a cell of the system. Beacon channel acquisition performance is enhanced by reducing beacon channel mutual interference. Each of the base stations broadcast a beacon signal into at least one of the cell sectors in a first time slot at least another one of the cell sectors in a second time slot different from the first time slot. The WTRU determines, at a particular position, which one of the beacon signals has the best signal quality, acquires the one beacon signal and establishes communications via the base station that generated the one beacon signal having the best signal quality.
