Open loop timing control for synchronous cdma systems |
摘要 |
Method and apparatus for maintaining synchronization in a CDMA communication system by operating closed loop timing control between a radio base unit and subscriber units, operating open loop timing control between the radio base unit and the subscriber units, and using timing information derived from the open loop to correct the closed loop. Generally the open loop is faster in response than the closed loop. The open loop timing control may be generated by using GPS data. A radio base station and a subscriber unit operating in accordance with these principles. |
