Data packet transmission
First Claim
1. A data transmitting method comprising:
- transmitting first data packets and second data packets from a transmitting station to a receiving station in containers;
wherein the first data packets comprise first data, in particular control instructions;
wherein the second data packets comprise second data;
wherein a first container comprises at least one first data packet;
providing the first container with a first error coding;
wherein a second container comprises at least one second data packet and no first data packet; and
providing the second container with a second error coding;
wherein the first error coding is stronger than the second error coding;
wherein the number of first and second data packets in the first container is smaller than the number of second data packets in the second container such that a first data payload transmitted in the first container is lower than a second data payload transmitted in the second container.

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.
