Abstract:
A mobile communication system having a plurality of mobile stations and at least one radio base station in which bidirectional communication using a time-divided CDMA system is performed between said mobile stations and said at least one radio base station,wherein each of said mobile stations measures a time difference having a fixed period of time subtracted therefrom, between a time that a time-divided CDMA burst signal is received from said radio base station and a time that a time-divided CDMA burst signal is transmitted by that respective mobile station in response to an instruction of said radio base station so that the transmitted time-divided CDMA burst signal may arrive at said radio base station at a start time position of a time slot of said time-divided CDMA system, and transmits information of the measured time difference to said radio base station.
