LEISTUNGSREGELUNGSPROTOKOLL FÜR RÜCKWÄRTSVERBINDUNG MIT HOCHVERÄNDERLICHER DATENRATE IN EINEM DRAHTLOSEN KOMMUNIKATIONSSYSTEM

摘要

A technique for implementing closed loop power control in a Code Division Multiple Access (CDMA) type wireless system which dynamically assigns coded channels on a demand basis. The technique maintains a proper power level, even when no traffic channels are allocated, by determining a link quality metric based upon the reverse link power received. This determination is made in response to a heartbeat signal sent at a rate which is only sufficiently fast to maintain code phase lock, for example, depending upon the expected maximum rate at which the subscriber unit will travel.
