Abstract
A method and system of communicating between a base station and a mobile station is disclosed. The base station may be the core of a cell site, which is defined by radio frequency radiation patterns. The cell site may be divided into a number of sectors, each defined respectively by radiation patterns. The mobile station, while within any of the sectors of the cell site, may communicate with the base station on a reverse link by encoding signals using a spreading sequence offset by a common time delay. On the forward link, each sector is assigned a respective time delay that is within the common time delay. While within a respective sector of the cell site, the mobile station may receive signals from the base station on the forward link that have been encoded with the spreading sequence offset by the sector's respective time delay.
