A METHOD AND SYSTEM FOR FAST SYNCHRONIZATION OF UPLINK AND A RECEIVER FOR BASE STATION'S ACCESS CHANNEL

摘要

A method for fastly synchronizing uplink in the synchronization code division multiple access(SCDMA) communication system, wherein the method comprising the steps of: (1) a mobile station selects one idle access time slot from a plurality of access time slot into which a access channel including in uplink be divided, in accordance with a base station's transmitting information; (2) the mobile transmits access code at point of time in said idle access time slot; (3) the base station detects said access code, and determines a time delay adjustment information for said mobile station; (4) the base station transmits said time delay adjustment information to the mobile station; (5) the mobile station adjusts transmission time thereof in accordance with received said time delay adjustment information, thereby making subsequently transmitting information arrive at the base station at standard access time.
