Wireless Scheduling with Increasing QoS for Inter-Dependent Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 5G NR networks struggle to efficiently communicate data sets with inter-dependent data, such as video frames, due to inadequate consideration of packet dependencies, leading to inefficiencies and high energy consumption, particularly in applications like Extended Reality (XR) where deterministic traffic patterns and high data rates are required.
Innovation Solution
The proposed solution involves configuring wireless networks to obtain a quality of service (QoS) indicator that increases reliability over time for data sets, ensuring that all data units are successfully communicated by scheduling resources accordingly, using a QoS indicator that identifies an increasing reliability level for successive data units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If legacy 5G NR scheduling is used for data sets with inter-dependent data, then general data communication is supported, but communication efficiency deteriorates and energy consumption increases due to random packet drops and retransmissions
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting QoS parameters (reliability levels, priority, resource allocation) based on the inter-dependency relationships within data sets. Different packets within the same data set are assigned different reliability requirements, allowing the system to optimize communication efficiency while maintaining necessary reliability for complete data set delivery
2Device complexity
If traditional scheduling without considering packet dependencies is used, then resource allocation is simple, but resource wastage increases when packets are dropped and retransmitted
Solution Approach 1:
The patent implements preliminary action by pre-identifying and marking packets with inter-dependency relationships before transmission. The access node analyzes data set structures in advance, assigns appropriate QoS parameters, and prepares scheduling decisions beforehand, preventing unnecessary retransmissions and reducing energy consumption without requiring complex real-time adjustments
3Ease of operation
If uniform reliability level is applied to all packets in a data set, then scheduling is straightforward, but complete data set delivery reliability deteriorates when early packets are dropped
Solution Approach 1:
The patent applies local quality by assigning different reliability levels to different packets within the same data set based on their specific importance and dependency relationships. Critical packets that must be delivered for complete data set reconstruction are assigned higher reliability levels, while less critical packets receive lower reliability levels, optimizing both scheduling feasibility and overall delivery reliability
