Abstract
Abstract A configuration of base stations and sectors within cells of a CDMA wireless communication network provide greater call handling capacity. By optimally configuring sectors of a cell controlled by multiple base stations, fewer channel elements are required to implement the desired service and a resultant system has improved signal demodulation, lower power requirements, improved performance, and lower cost for a service provider. The base stations are configured to support "N" sectored cells to ensure that each cell has a maximum amount of capacity for all mobile users therein. This method involves configuring the sectors serviced by a same base station adjacent to one another. By configuring the sectors associated with base stations in this manner, there are fewer instances of soft handoff and more instances of softer handoff. Furthermore, configuring the sectors to be adjacent to one another ensures optimal power collection by each of the sectors during the communication process.
