Code division multiple access (CDMA) communication system
First Claim
1. An infrastructure node in a wireless network comprising:
- a GPS receiver;
circuitry configured to synchronize a timing of the infrastructure node in response to an output of the GPS receiver;
circuitry configured to receive a request for system parameters from a different infrastructure node; and
circuitry configured to send a response to the request to the different infrastructure node, wherein the response has system parameters comprising at least one of a forward link power control parameter and an interference level parameter, wherein the system parameters are associated with forward link communications between the infrastructure node and a subscriber unit.

Abstract
A subscriber unit for use in a multiple access spread-spectrum communication system includes a spread spectrum radio interface, responsive to a rate function signal from a base station, and first and second despreaders. The base station assigns the rate function spread-spectrum message channels and the first despreader recovers and modifies an information signal one of the spread spectrum message channels. The information channel mode is then modified for processing by the second despreader, with the second despreader supporting a different information signal rate. The subscriber unit has a capability of communicating with a dynamically changing a transmission rate of an information signal which includes multiple spread spectrum message channels. The system includes a closed loop power control system for maintaining a minimum system transmit power level for a radio carrier station and the subscriber units, and system capacity management for maintaining a maximum number of active subscriber units for improved system performance.
