ABSTRACT:
Using the attribute “priority” to achieve a stronger Forward Error Correction (FEC) for Radio Link Control (RLC) Control Protocol Data Units (PDUs) transmitted via the High Speed Downlinik Shared Channel (HS-DSCH) also entails prioritized handling so that an RLC Control PDU is likely to overhaul an RLC Data PDU. As a consequence the RLC protocol operation can severely be disturbed, since it relies on in-sequence delivery of control and data PDUs. According to an exemplary embodiment of the present invention, two types of containers are provided in which data packets may be transmitted, wherein the first type of container is provided with a stronger error coding than the second type of container and wherein data packets which comprise control instructions are only transmitted in the first container type with the stronger error correction. Due to this, an improved forward error correction for control PDUs of the AM RLC protocol of Universal Mobile Telecommunications System (UMTS) may be provided.
