Parallel Channel Detection for Low-Interruption Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing channel detection methods in LAA systems introduce service degradation due to prolonged and frequent power measurements, leading to increased transmission interruptions and system overload, especially when switching operational channels based on DCS operations.
Innovation Solution
A fast scheme for channel detection before transmission is implemented, where all supported channels are assessed simultaneously or in parallel, using existing communication protocols to minimize interruptions and reduce latency, with results delivered efficiently via existing message types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional sequential channel detection method is used, then measurement accuracy is improved, but transmission interruptions increase and service degradation occurs
Solution Approach 1:
The patent performs channel detection for all supported channels before transmission is actually needed. The base station assesses multiple channels in advance and stores the detection results, so when transmission is required, the channel is already validated and ready for immediate use, eliminating transmission interruptions.
Solution Approach 2:
The patent divides the channel detection process into separate parallel operations for each supported channel. Instead of sequentially detecting one channel at a time, the base station segments the detection task and executes multiple channel assessments simultaneously, reducing total detection time while maintaining accuracy.
2Productivity
If frequent power measurements are performed for DCS operations, then channel selection performance is improved, but system overhead increases and service degradation occurs
Solution Approach 1:
The patent maintains continuous channel detection capability by periodically assessing all supported channels and updating the channel status information. This continuous monitoring provides up-to-date channel conditions for DCS operations without requiring frequent interruptive measurements, reducing system overhead while maintaining performance.
3Reliability
If channel detection is performed for all supported channels, then transmission reliability is improved, but detection time and processing load increase
Solution Approach 1:
The patent performs comprehensive channel detection for all supported channels in advance, before transmission is actually needed. By detecting all channels beforehand and storing the results, the system ensures transmission reliability through thorough assessment while avoiding time loss during actual transmission operations.
Solution Approach 2:
The patent implements periodic channel detection where all supported channels are assessed at regular intervals. This periodic approach balances thorough detection for reliability with time management, as channels are detected comprehensively but not continuously, reducing overall processing load while maintaining transmission reliability.
