Abstract:
A method for high-speed data transmission between a mobile station and a mobile communications network in a mobile communications system based on time division multiple access (TDMA), said method comprising:using for a transmitting direction a frequency different from a frequency used for a receiving direction;allocating for the data transmission at least two time slots in at least one of the transmitting and the receiving direction;employing 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;further keeping allocated ones of the time-slots that are not used for data transmission; andselecting ones of the time-slots used for the data transmission in each direction such that even at a maximum timing advance the mobile station does not have to send and receive simultaneously with one set of radio parts.
