Abstract
A mobile communications system and method for use in a high-speed data transmission between a mobile station and a mobile communications network in the mobile communications system based on time division multiple access (TDMA). The mobile communications system is arranged to use a different frequency for a transmitting direction and a receiving direction. The mobile communications system includes a time-slot allocating mechanism arranged to allocate at least two time slots in at least one of the transmitting and the receiving direction for data transmission; a time-slot employing mechanism arranged to employ time-slots asymmetrically so that in the transmitting direction and in the receiving direction a number of the time-slots corresponds to a currently required data transmission rate in each respective direction, the time-slot employing mechanism further arranged to keep allocated ones of the time-slots that are not used for data transmission; and a time-slot selecting mechanism arranged to select ones of the time-slots used for the data transmission in each direction such that even at a maximum timing advance.
