Abstract: 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.

Abstract: A TDMA/CDMA 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 can be simultaneously transmitted between mobile stations and a base station 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 frequency synchronization of the mobile stations in the downward direction in which a symbol sequence is transmitted. From received signals, the mobile station to be synchronized determines estimated values for the symbol sequence and compares these estimated values with a reference sequence. It is thereby possible to calculate a phase drift in the estimated values with reference to the reference sequence wherein a frequency offset, which is used for frequency synchronization, is determined from the phase drift.

Abstract: The invention relates to a method and a base station for transmitting data in a downlink direction over a radio interface in a mobile radio communications system. The base station transmits the data in the downlink direction to a radio station in radio blocks that are organized in a time division multiplex method. Recurring training sequences are inserted between the radio blocks without decreasing the transmission power used for transmitting the data. The radio station carries out a channel estimation by means of the training sequences.

At the reception side, the multi-voice frames (MSF4) are in turn divided into voice-coded voice frames (S4) and, subsequently, the digital voice information contained in the transmitted voice frames is in turn converted into an analog voice signal.
