1. A method for power control of a mobile station in a mobile telecommunications system, the method comprising:

  • transmitting data over a radio path between a mobile station and a base station of a fixed radio network as bursts in time slots of successive frames;

    allocating the mobile station at least two time slots in each frame for transmitting a high-speed data signal having a data rate which is higher than that supported by use of one time slot in each frame;

    splitting the high-speed data signal into a plurality of lower-speed sub-signals corresponding in number to the number of allocated time slots;

    the transmitting including transmitting the lower-speed sub-signals over the radio path as respective separate bursts in each of the allocated time slots;

    upon reception of the separate bursts transmitted over the radio path, combining the lower-speed sub-signals, thereby restoring the high-speed data signal;

    measuring, at the mobile station in each time slot allocated to the mobile station, at least one characteristic of a received signal, the characteristic selected from the group consisting of signal level and signal quality; and

    controlling the transmitting power of the mobile station on the basis of one of (a) a combination of measurement results of two or more time slots assigned to the mobile station, and (b) a measurement result of the poorest time slot in relation to the at least one characteristic.
