A METHOD OF CONTROLLING INITIAL POWER RAMP-UP IN CDMA SYSTEMS BY USING SHORT CODES |
摘要 |
A system and method for reducing the reacquisition time of a subscriber unit by a base station. The reacquisition time is reduced in that an access signal from a subscriber unit at a predetermined power transmission level is transmitted; said transmission power and a code phase delay of said access signal are varied until a confirmation signal is received from said base station; centered around a maximum code phase delay said access signal is detected at said base station when a sufficient power level and the maximum code phase delay have been achieved; a confirmation signal is transmitted from said base station when said access signal has been detected; said confirmation signal is received at said subscriber unit; and the variation in transmission power and the code phase delay are ceased at said subscriber unit when said confirmation signal is received. <IMAGE> |
