ABSTRACT:
The invention relates to a wireless network comprising a radio network controller and a plurality of assigned terminals, which are provided for exchanging data according to the hybrid ARQ method of type II or III and each form a receiving and/or transmitting side. A physical layer of a transmitting side is arranged forstoring coded transport blocks in a memory, which blocks contain at least a packet data unit delivered by the assigned radio link control layer and can be identified by a packet data unit sequence number,storing abbreviated sequence numbers whose length depends on the maximum number of coded transport blocks to be stored and which can be shown unambiguously shown in a packet data unit sequence number, and fortransmitting coded transport blocks having at least the assigned abbreviated sequence numbers.a physical layer of a receiving side is provided for testing the correct reception of the coded transport block and for sending a positive acknowledge command to the transmitting side over a back channel when there is correct reception and a negative acknowledge command when there is error-affected reception.
