Title: High-speed data transmission in mobile communication networks
Inventor: RASANEN JUHA
IPC: H04W92/18
Filed: 1996-03-06
Granted: 2005-02-22
Abstract: The invention relates to a digital mobile system and a method for high-speed data transmission in a digital mobile system. The mobile network allocates n parallel rate-adapted traffic channels to a high-speed user data signal which requires a data transfer rate R user within a range (n-1)*R ch<R user<n*R ch, wherein R ch is the maximum transmission rate of a single traffic channel. The user data signal is divided in the transmitter into transmission frames (L, L+1, L+2) for transmission via the parallel traffic channels (ch1-chn) in such a way that all the information bits in the transmission frames of n-1 traffic channels carry user data bits (DATA), and the user data transfer rate of each of the n-1 traffic channels is R ch. In the frames of the nth traffic channel (chn) the number of the information bits carrying user data bits (DATA) is selected to correspond to the user data rate R user-(n-1)*R ch exceeding the capacity of the other n-1 traffic channels.  The remaining information bits in the frames of the nth traffic channel carry stuff bits (FILL).
