Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If distributed antenna system is deployed with extensive optical fiber connections, then coverage and capacity are increased, but deployment cost and engineering complexity increase significantly
Solution Approach 1:
The patent combines multiple antenna units (macrocell antenna and auxiliary antennas) into a coordinated antenna array system that shares common baseband and radio frequency resources. This merging approach enables the system to achieve distributed antenna coverage benefits while reducing deployment complexity by eliminating the need for separate optical fiber connections to each antenna unit, as they share common resource pools.
2Productivity
If more cells are split to increase capacity, then wireless network capacity increases, but interference between split cells increases and prevents significant capacity improvement
Solution Approach 1:
The patent implements coordinated transmission with different transmission modes for different user equipment. The system adjusts local transmission characteristics (transmission mode, resource allocation) based on user equipment capabilities and channel conditions, allowing capacity optimization without causing harmful interference. This local quality adjustment resolves the contradiction by enabling capacity increase through intelligent resource management rather than simple cell splitting.
3Reliability
If manual selection of antenna locations is performed during planning, then system performance is optimized, but engineering implementation becomes troublesome and time-consuming
Solution Approach 1:
The patent implements self-service through automatic antenna resource configuration. The controller automatically determines optimal antenna units and transmission modes based on user equipment capabilities and channel conditions, eliminating the need for manual antenna location selection during planning. The system serves itself by dynamically allocating resources based on real-time conditions, thus maintaining system performance while greatly simplifying engineering implementation.
4Area of stationary object
If auxiliary antennas are distributed at remote ends connected through optical fibers, then coverage is extended, but deployment cost increases due to large-scale optical fiber requirements
Solution Approach 1:
The patent merges multiple auxiliary antennas into a coordinated array that shares common baseband and radio frequency resource pools. This approach extends coverage area through distributed antenna deployment while dramatically reducing optical fiber requirements, as all antenna units share common resource infrastructure rather than requiring dedicated connections to each antenna.
