Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If data scheduling transmission aims to maximize throughput, then system productivity is improved, but XR experience deteriorates and the quantity of satisfied users decreases
Solution Approach 1:
The patent changes the scheduling parameter from throughput maximization to XR experience maximization. The network device uses network transmission quality information (indicating XR experience) and channel state information to determine scheduling policies, thereby optimizing the balance between productivity and experience quality
Solution Approach 2:
The patent introduces feedback mechanisms where terminal devices report network transmission quality information to network devices. This feedback loop enables continuous optimization of scheduling policies based on actual XR experience, allowing the system to adapt and improve user satisfaction while maintaining efficient resource utilization
2Productivity
If multi-user MIMO pairing is implemented, then system capacity is increased, but interference between users increases and XR experience deteriorates
Solution Approach 1:
The patent applies local quality by filtering terminal devices based on individual network transmission quality information before pairing. Not all terminal devices are treated equally; only those meeting quality thresholds are selected for MU-MIMO pairing, ensuring that each user receives personalized service quality appropriate to their channel conditions and XR experience requirements
Solution Approach 2:
The patent implements dynamic scheduling policies where the network device determines pairing and scheduling sequences based on real-time network transmission quality information and channel state information. This dynamic adaptation allows the system to optimize the balance between system capacity and interference management for each specific scenario
