Adaptive Beamforming Scanning for Non-Uniform Network Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communications systems face challenges in efficiently receiving identification signals, particularly in non-uniform network coverage areas, leading to network outages and bottlenecks during random access procedures.
Innovation Solution
The method involves adaptive beamforming scanning, where a network device obtains a beam pattern defined by non-uniform directional coverage and scans with directional beams in spatial directions to efficiently receive identification signals from wireless devices, avoiding equal time duration in each beam and adjusting beam widths and durations based on coverage demands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If equal time duration beam scanning is used in all directions, then the scanning procedure is simple and uniform, but network coverage holes appear in directions with lower coverage demand
Solution Approach 1:
The patent applies local quality by configuring different beam scanning parameters (time duration, beam width) for different spatial directions based on their specific coverage demands. Directions with higher coverage demand receive more scanning resources, while directions with lower demand use fewer resources, optimizing overall coverage without uniform complexity
Solution Approach 2:
The patent implements dynamic beam scanning where the network device adaptively adjusts beam width and time duration for each direction based on real-time coverage requirements. This dynamic adaptation allows the system to respond to changing network conditions and coverage demands in different directions
2Reliability
If beam scanning is performed in all directions with sufficient time, then coverage holes are minimized, but bottlenecks occur in random access procedures
Solution Approach 1:
The patent changes key beam scanning parameters (time duration, beam width) based on direction-specific requirements. By adjusting these parameters dynamically, the system achieves reliable signal reception in critical directions while maintaining random access efficiency through optimized scanning durations that prevent bottlenecks
3Measurement precision
If directional beams are used to improve signal quality, then reception of identification signals is enhanced, but the system becomes more complex compared to omnidirectional scanning
Solution Approach 1:
The patent segments the scanning process into multiple directional beams, each targeting specific spatial directions. This segmentation allows the system to concentrate resources on directions requiring enhanced signal quality while using simpler scanning in other directions, balancing performance and complexity
