Method and arrangement for high-speed data transmission in TDMA mobile telecommunications system
First Claim
1. A method for high-speed data transmission in a mobile telecommunications system, comprising:
- splitting a high-speed data signal into at least two signals of lower speed prior to a transmission over a radio path;
allocating, for high-speed data transmission, for a mobile station at least two time slots from each frame corresponding to a number of said at least two signals of lower speed;
carrying out modulation and burst building operations separately to each of said at least two signals of lower speed; and
transmitting data over the said radio path between a mobile station and a base station as bursts in a time slot allocated to the said mobile station by successive frames, so that each of said at least two data signals of lower speed is transmitted in a different one of the said at least two time slots.

Abstract
A method and arrangement for high-speed data transmission in a TDMA mobile telecommunications system. A high-speed data signal is split into at least two signals of lower speed prior to transmission over a radio path. At least two time slots for each frame are allocated for a mobile station. The time slots from each frame correspond to a number of the signals of lower speed. Modulation and burst building operations are carried out separately for each of the signals of lower speed. Data is transmitted over the radio path between the mobile station and a base station as bursts in a time slot allocated to the mobile station by successive frames, so that each of the signals of lower speed is transmitted in a different one of the time slots.

5. An arrangement for high-speed data transmission in a mobile telecommunications system in which data is transmitted over a radio path between a mobile station and a base station as bursts in time slots allocated to said mobile station by successive frames, said arrangement comprising:
-
means for splitting a data signal, having a speed being higher than a maximum data transfer rate in a time slot, into at least two signals of lower speed prior to transmission over said radio path; means for performing burst formation and modulation operations separately to each of said at least two signals of lower speed; means for performing demodulation operation separately for each of said at least two signals of lower speed; and means for combining said at least two signals of lower speed received over said radio path, wherein said mobile station is allocated at least two time slots in each successive frame for high-speed data transmission so that each of said at least two signals of lower speed is transmitted over said radio path in a respective time slot. - View Dependent Claims (6, 7, 8, 9, 10, 11)

12. A method for high-speed data transmission over an air interface between a mobile station and a fixed mobile communication network in a digital mobile communication system, said method comprising:
-
splitting a high-speed data signal into at least two signals of lower speed in said mobile communication network at a location remote from a serving base station; transmitting said at least two signals of lower speed to said serving base station; allocating, for high-speed data transmission, for a mobile station at least two time slots from each frame, a number of said at least two time slots corresponding to a number of said at least two signals of lower speed; carrying out channel coding, interleaving and modulation operations separately to each one of said at least two signals of lower speed at a transmitting end; and transmitting each of said at least two signals of lower speed in a different one of said at least two allocated time slots over a radio path from said serving base station to said mobile station.

13. An arrangement for high-speed data transmission in a mobile telecommunications system over a radio path between a mobile station and a base station, said arrangement comprising:
-
means for splitting a high-speed data signal, having a speed higher than a maximum data transfer rate of one traffic channel, into at least two signals of lower speed in said mobile telecommunications system at a location remote from said base station; means for transmitting said at least two signals of lower speed to said base station; said mobile station being allocated at least two time slots for high-speed data transmission so that each of said at least two signals of lower speed is transmitted over said radio path in a respective one of said at least two time slots; means for performing channel coding, interleaving and modulation operations separately to each one of said at least two signals of lower speed at a transmitting end; means for transmitting each of said at least two signals of lower speed in a different one of said at least two allocated time slots over said radio path from said base station to said mobile station; and means for performing demodulating, deinterleaving and channel decoding operations separately to each one of said at least two signals of lower speed at a receiving end.
