ABSTRACT:
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.sub.user within a range (n-1)*R.sub.ch <R.sub.user <n*R.sub.ch, wherein R.sub.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.sub.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.sub.user -(n-1)*R.sub.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).
