[0025] For the purposes of this disclosure, a "transmission" is the first transmission of a particular protocol data unit (PDU) characterized by a sequence number or corresponding identifier. The term "retransmission" refers to any additional transmission related to a PDU with this sequence number. This includes the retransmission of the correct coded version (eg, with HARQ type 1) of the PDU as well as the retransmission of the new coded version of the PDU. The size of the retransmission can be the same or different than the first transmission. Also, with reference to ARQ and / or HARQ functionality, the terms ARQ, ARQ protocol, etc. will be used below in their general meaning.
[0026] figure 1 is a schematic overview of an example WCDMA communication system in which the present invention may be used. The illustrated system 100 includes a radio access network (RAN), such as a universal terrestrial radio access network (UTRAN), and a core network 130 . The RAN performs radi...
