Abstract

The invention relates to a method for transmitting packet switched data in a mobile communications system using an ARQ protocol. In the method the receiver requests, if necessary, retrasnmissions of the originally sent transmission unit, until the quality of the combined transmission unit formed of the originally sent transmission unit and its retransmitted copies corresponds to the predetermined quality level. The signal is not detected until after this. If the packet is interleaved and encoded and it is found out that the packet is not faultless, retransmissions of the transmission units of the packet that are of the poorer quality are requested. The invention also relates to a mobile communications system implementing the method of the invention.
