Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a fixed LIS is used to serve user equipment, then deployment simplicity and low energy consumption are improved, but the number of users that can be served is limited
Solution Approach 1:
The system segments the LIS functionality into fixed LIS components (for stable coverage) and mobile LIS components (for user mobility support). The electronic apparatus independently controls beamforming for each LIS type, allowing simultaneous service to multiple users through differentiated beam management strategies.
Solution Approach 2:
The electronic apparatus implements a universal beam management framework that handles both fixed and mobile LIS scenarios through a single system architecture. The apparatus can dynamically switch between serving fixed LIS users and mobile LIS users, providing multi-functional capability while maintaining deployment simplicity of fixed LIS.
2Adaptability or versatility
If a mobile LIS is used to serve user equipment, then user coverage and mobility support are improved, but antenna angle adjustment complexity and energy consumption increase
Solution Approach 1:
The electronic apparatus acts as an intermediary between the mobile LIS and user equipment, performing centralized beam management and angle adjustment calculations. This mediator approach simplifies the mobile LIS implementation by offloading complex control functions to the electronic apparatus, reducing on-device complexity while maintaining comprehensive user coverage.
Solution Approach 2:
The system implements dynamic beam management where the electronic apparatus continuously adjusts beamforming parameters based on real-time channel conditions and user positions. This dynamic adaptation allows the mobile LIS to maintain optimal coverage without requiring complex mechanical antenna angle adjustments, reducing both complexity and energy consumption.
3Reliability
If multiple LIS types are jointly used to serve user equipment, then communication quality is improved, but system complexity increases
Solution Approach 1:
The electronic apparatus implements self-service beam management by autonomously measuring channel quality for multiple LIS types and independently determining optimal beam configurations. The apparatus automatically coordinates between fixed and mobile LIS resources without requiring complex external control systems, improving communication quality while managing system complexity through autonomous operation.
Solution Approach 2:
The system employs feedback mechanisms where the electronic apparatus continuously monitors channel quality metrics from user equipment served by multiple LIS types. Based on this feedback, the apparatus dynamically adjusts beamforming parameters and resource allocation for each LIS type, optimizing communication quality while adapting to changing system conditions without increasing inherent complexity.
