Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems, such as 5G and 6G, have limited coverage areas, making it difficult to provide extensive coverage in industrial settings like construction sites without wired connections, and existing solutions require proprietary directional wireless links or additional base stations with different communication technologies.
Innovation Solution
End devices are configured as additional base stations using existing mobile communication technology, enabling seamless expansion of coverage by integrating them into the wireless industrial edge cloud system, allowing them to operate autonomously and flexibly without requiring additional access credentials or authentication information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple base stations are deployed to expand network coverage and support more terminal devices, then system capacity and coverage are improved, but system complexity and interference management difficulty increase
Solution Approach 1:
The system divides the network into multiple base stations, each independently managing its own terminal devices. Each base station processes scheduling decisions and interference management locally, breaking down the complex multi-base station coordination into manageable independent units that can operate semi-autonomously.
Solution Approach 2:
The base station performs preliminary scheduling of uplink and downlink resources before actual data transmission. By pre-allocating time-frequency resources and predicting interference patterns, the system prepares coordination strategies in advance, reducing real-time complexity when multiple base stations operate simultaneously.
2Reliability
If wireless resources are allocated dynamically to support diverse QoS requirements, then service quality is improved, but scheduling complexity and resource management overhead increase
Solution Approach 1:
The scheduling mechanism applies different resource allocation strategies to different terminal devices based on their specific QoS requirements. High-priority traffic receives guaranteed resources while low-priority traffic uses remaining resources, allowing each device to receive locally optimized service quality without requiring complex global optimization.
Solution Approach 2:
The system dynamically adjusts scheduling parameters such as time-frequency resource allocation, power levels, and modulation schemes based on channel conditions and QoS requirements. By changing these parameters adaptively, the system maintains service quality while using relatively simple scheduling rules at each base station.
3Productivity
If uplink and downlink resources are shared in TDD mode to improve spectral efficiency, then resource utilization is improved, but interference management complexity and signal detection difficulty increase
Solution Approach 1:
The base station performs preliminary detection of uplink signals from multiple terminal devices before downlink transmission. By detecting and characterizing uplink channel conditions and interference patterns in advance, the base station can pre-calculate appropriate downlink beamforming weights and resource allocation to mitigate interference before it occurs.
Solution Approach 2:
The system implements feedback mechanisms where terminal devices report channel quality indicators and interference levels back to the base station. This feedback enables the base station to adjust uplink-downlink resource allocation and power control parameters to optimize spectral efficiency while maintaining acceptable signal detection performance in TDD mode.
