Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If beamforming is used to increase signal gain in mmWave bands, then transmission distance and data rate are improved, but service outages occur in regions with insufficient beams
Solution Approach 1:
The patent implements dynamic beam adjustment by continuously monitoring terminal locations and beam coverage areas, then adapting beam configurations in real-time. The base station receives terminal location information, determines which terminals fall within which beam coverage areas, and adjusts beam parameters dynamically to ensure continuous service coverage as terminals move through different coverage zones.
Solution Approach 2:
The patent changes beam operation parameters including beam width, beam direction, and beam power based on terminal locations and coverage requirements. By adjusting these parameters dynamically, the system optimizes signal gain for active terminals while extending coverage to prevent service outages in previously underserved regions.
2Reliability
If the number of beams is increased to cover more areas, then service coverage is improved, but beamforming efficiency decreases due to excess beams
Solution Approach 1:
The patent applies different beam configurations to different spatial regions based on local requirements. Each beam coverage area is optimized independently according to the density and location of terminals within that specific region, rather than using a uniform beam configuration across the entire service area. This allows efficient resource allocation where more beams are deployed in high-density areas and fewer in low-density areas.
Solution Approach 2:
The patent activates only the necessary number of beams based on current terminal locations and service requirements, rather than maintaining all possible beams continuously. By selectively activating beams only when needed and adjusting the number of active beams dynamically, the system achieves sufficient coverage without the overhead of maintaining excessive beams, thus improving beamforming efficiency.
3Ease of operation
If beam configurations are fixed to simplify operation, then device complexity is reduced, but the system cannot adapt to environmental changes causing service outages
Solution Approach 1:
The patent implements self-service beam adjustment where the base station automatically monitors terminal locations, determines coverage requirements, and adjusts beam configurations without manual intervention. The system autonomously receives terminal location information, calculates which terminals are within which beam coverage areas, and dynamically reconfigures beams to maintain optimal service, eliminating the need for complex manual configuration management while achieving high adaptability.
Solution Approach 2:
The patent establishes a feedback loop where terminal location information is continuously fed back to the base station, which then adjusts beam configurations based on this feedback. The system monitors the relationship between terminal positions and beam coverage areas, and uses this information to dynamically optimize beam parameters, ensuring the system adapts to environmental changes while maintaining simplified operation through automated closed-loop control.
