PDU Bearer Selection for Target Error Rate in XR Transmission

The patent applies local quality by differentiating PDU transmission handling based on PDU Set characteristics. Critical PDU Sets (e.g., those with strict error rate requirements or high importance) are transmitted with enhanced reliability measures such as duplication or prioritized scheduling, while non-critical PDU Sets use standard transmission. This selective approach improves overall PSER performance without uniformly increasing complexity across all transmissions.

The patent segments PDU transmission into different categories based on PDU Set attributes such as error rate requirements, importance levels, or service types. By dividing the transmission handling into multiple pathways (e.g., critical vs. non-critical streams), the system can apply appropriate reliability measures to each segment, thereby achieving target PSER for critical traffic without unnecessarily complicating the handling of all PDUs.

The patent implements dynamic bearer selection where the transmitting entity adaptively chooses appropriate bearers based on real-time PDU Set characteristics and network conditions. Instead of statically configuring multiple bearers for all traffic, the system dynamically assigns bearers with varying reliability configurations only when needed for specific PDU Sets, thereby improving transmission reliability while minimizing the operational complexity of managing multiple bearers.

The patent changes transmission parameters such as bearer selection, redundancy level, or scheduling priority based on PDU Set attributes. By adjusting these parameters dynamically according to the specific requirements of each PDU Set (e.g., using higher reliability bearers for critical traffic), the system achieves improved transmission reliability without permanently increasing device complexity, as the complexity is activated only when required.

The patent applies local quality by providing priority transmission resources specifically to critical PDU Sets that require high reliability, while allowing non-critical PDU Sets to utilize standard or alternative radio resources. This selective prioritization ensures that reliability improvements are concentrated where needed (for critical traffic) without unnecessarily consuming additional network capacity for non-critical traffic, thereby maintaining overall network productivity.

The patent implements partial prioritization where only the necessary portion of radio resources is allocated to critical PDUs to achieve the required PSER target. Instead of uniformly prioritizing all traffic or over-provisioning resources, the system applies priority handling only to the extent needed for critical PDU Sets, thus improving reliability for essential traffic while avoiding excessive resource consumption that would reduce overall network capacity and productivity.
