Multi-Channel Data Duplication Switching for 5G Link Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing 5G CU/DU separated network architecture experiences high transmission resource consumption due to data duplication transmission, as the CU cannot determine the downlink quality of DUs in time, leading to inefficient use of resources.
Innovation Solution
A data transmission method that involves obtaining channel quality measurements across multiple channels, determining whether to activate or deactivate the data duplication transmission function based on these measurements, and performing data transmission accordingly to optimize resource use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data duplication transmission is performed on multiple channels, then reliability of data transmission is improved, but transmission resource consumption increases
Solution Approach 1:
The patent implements dynamic activation and deactivation of data duplication transmission based on real-time channel quality measurements. The network device monitors channel conditions and adaptively switches between duplication and non-duplication modes, making the transmission mode flexible rather than static. This resolves the contradiction by enabling reliability improvement only when channel conditions deteriorate, rather than continuously consuming resources.
Solution Approach 2:
The patent changes the parameter of transmission mode (from static duplication to dynamic selection between duplication and non-duplication) based on channel quality parameters. By monitoring channel quality metrics and adjusting the transmission strategy accordingly, the system optimizes the balance between reliability and resource consumption, activating duplication only when channel quality falls below thresholds.
2Reliability
If data duplication transmission is continuously activated, then data transmission reliability is maintained, but transmission resources are wasted
Solution Approach 1:
The patent implements periodic channel quality measurements and evaluation to determine whether to activate or deactivate data duplication transmission. Instead of continuous activation, the system periodically assesses channel conditions and switches modes accordingly. This periodic evaluation mechanism ensures reliability is maintained only when necessary, preventing continuous resource waste while keeping the system responsive to channel changes.
Solution Approach 2:
The network device autonomously monitors its own channel conditions and makes decisions about activating or deactivating duplication transmission without external intervention. This self-service mechanism allows the system to automatically adjust resource allocation based on actual transmission needs, preventing waste while maintaining reliability when required.
3Speed
If the CU cannot determine downlink quality of DUs in time, then response speed decreases, but system complexity is reduced
Solution Approach 1:
The patent implements preliminary channel quality measurements and pre-established thresholds for determining when to activate duplication transmission. By having measurement mechanisms and decision criteria prepared in advance, the system can quickly respond to channel changes without complex real-time analysis. The pre-configured thresholds and measurement frameworks enable fast decision-making while keeping the system structure relatively simple.
