Estimating the term…
A radio communications system provides frequency channels which are formed both by time slots and by broadband frequency ranges, and in which information from a plurality of connections is simultaneously transmitted between mobile stations and base stations wherein it is possible to distinguish the information from different connections in accordance with a connection-specific fine structure. Frequency channels are repeatedly provided for time synchronization of the mobile stations in the downward direction in which a signal form is transmitted in addition to information from further connections. The mobile station to be synchronized determines from received signals at least one instant of the arrival of the signal form, which is subsequently used by the mobile station for time synchronization. The system is advantageously applied, for example, in TDD mode for the third mobile communications generation which combines a TDMA and CDMA subscriber separation method.
A method for time synchronization of a mobile station of a radio communications system, the method comprising the steps of:
A mobile station of a radio communications system for use in connection with a method for time synchronization of the mobile station, wherein the radio communications system provides frequency channels which are formed both by time slots and by broadband frequency ranges and in which information from one or more connections is simultaneously transmitted between mobile stations and base stations, wherein information from different connections is distinguishable by spread codes, wherein one of the frequency channels is provided for repeated time synchronization of the mobile stations in a downward direction, and wherein a plurality of different known signal forms are transmitted within the one frequency channel in addition to information from further connections, the mobile station comprising:
A base station for use in connection with a method for time synchronization of a mobile station of a radio communications system provides frequency channels which are formed both by time slots and by broadband frequency ranges and in which information from one or more connections is simultaneously transmitted between mobile stations and base stations, wherein information from different connections is distinguishable by spread codes, and wherein one of the frequency channels is provided for repeated time synchronization of the mobile stations in a downward direction, the base station comprising:
A method for time synchronization of a mobile station of a radio communications system, the method comprising the steps of:
A method for time synchronization of a mobile station of a radio communications system, the method comprising the steps of:
