Abstract
A mobile radio system conveys frames between at least one mobile station and at least one base station, each frame comprising N time slots, a burst of data being transmitted in each time slot, and each time slot being associated with a separate call between a mobile station and a base station. For each call over a transmission channel, the quality of the transmission channel is analyzed and, on the, basis thereof, a selection is made between first and second modes of transmission. In the first mode of transmission data to be transmitted is organized in first blocks obtained by a first encoding of source blocks, each of the first blocks has a size greater than the content of (P-1) bursts, where P is an even number at least equal to 2, and the data of the same first block is distributed between at least P bursts. In the second mode of transmission the data to be transmitted is organized in second blocks each having a size less than or equal to the content of P/2 bursts, the data of the same second block is distributed into at most P/2 bursts, at least P/2 bursts are available relative to the first mode of transmission, and an automatic retransmission request mechanism is used to retr…
