Asymmetric high-speed data transmission apparatus and method in a mobile communications network
First Claim
1. 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; and
selecting 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.

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.
