Data packet transmission
First Claim
1. Method of transmitting first data packets and second data packets from a transmitting station to a receiving station, wherein the first data packets comprise first data, in particular control instructions;
- wherein the second data packets comprise second data;
wherein the first data packets and the second data packets are transmitted from the transmitting station to the receiving station in containers;
wherein a first container comprises at least one first data packet;
wherein the first container is provided with a first error coding;
wherein a second container comprises at least one second data packet and no first data packet;
wherein the second container is provided with a second error coding; and
wherein the first error coding is stronger than the second error coding.

Abstract
Using the attribute “priority” to achieve a stronger FEC for RLC Control PDUs transmitted via the 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 UMTS may be provided.
