Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in efficiently handling multi-stream data transmission, particularly for XR services, due to the need for complex modifications in DCI formats and high operational complexity when using a single CS-RNTI to schedule multiple TBs with non-fixed packet sizes and misaligned SPS/CG adjustments.
Innovation Solution
Implement a multi-stream data transmission scheme where scheduling identification information, such as CS-RNTI, is configured specifically for each data stream based on its characteristics, allowing for enhanced SPS/CG transmission by associating multiple pieces of scheduling identification information with different data streams.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single CS-RNTI is used to schedule multiple TBs in multi-stream data transmission, then device complexity is reduced, but operational complexity increases and data transmission efficiency deteriorates
Solution Approach 1:
The patent divides the scheduling identification information into multiple CS-RNTIs, with each CS-RNTI dedicated to a specific data stream. This segmentation allows the system to handle multiple TBs across different data streams independently, reducing operational complexity while maintaining manageable device complexity through structured organization.
2Productivity
If multiple pieces of scheduling identification information are configured for different data streams, then data transmission efficiency is improved, but device complexity increases
Solution Approach 1:
The patent segments scheduling identification information into multiple CS-RNTIs, each dedicated to a specific data stream. This allows parallel processing of multiple data streams with their own scheduling parameters, improving data transmission efficiency while keeping device complexity manageable through structured organization of the multiple identifiers.
Solution Approach 2:
The patent applies local quality by assigning specific scheduling characteristics to each data stream through dedicated CS-RNTIs. Each data stream can have optimized scheduling parameters tailored to its specific requirements, improving overall data transmission efficiency while maintaining clear local management of scheduling information.
3Adaptability or versatility
If SPS/CG adjustments are made for multiple TBs with non-fixed packet sizes, then adaptability is improved, but operational complexity increases
Solution Approach 1:
The patent segments SPS/CG adjustments into separate control processes for each data stream, with each CS-RNTI managing its own SPS/CG parameters independently. This allows flexible adaptation to non-fixed packet sizes in each stream while reducing operational complexity through modular, stream-specific adjustment procedures.
Solution Approach 2:
The patent implements dynamic SPS/CG adjustments for each data stream based on real-time transmission requirements. Each CS-RNTI can independently adjust its SPS/CG parameters to adapt to varying packet sizes and traffic conditions, improving system adaptability while maintaining manageable operational complexity through decentralized control.
