Beam Scanning With Obstacle Information for Target UE Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity of beam scanning processes increases with smaller beam angles due to the need for more beams, especially in high-frequency communication systems, making it inefficient.
Innovation Solution
Determine an optimal beam by acquiring obstacle information and position information of a target UE, allowing for beam selection without full-angle scanning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If more beams are used for beam scanning to cover high-frequency bands, then coverage and communication reliability are improved, but system complexity and scanning overhead increase
Solution Approach 1:
The base station performs preliminary actions by acquiring obstacle information in advance and using it to pre-determine the optimal beam for the target UE. This preliminary preparation eliminates the need for exhaustive beam scanning, directly resolving the contradiction by maintaining reliable communication through informed beam selection while reducing system complexity and scanning overhead
Solution Approach 2:
The patent replaces the mechanical beam scanning process with an information-based determination approach. Instead of physically scanning through multiple beams to find the optimal one, the system uses obstacle information and UE position data to directly calculate and determine the optimal beam, substituting a complex mechanical search process with a more efficient computational method
2Measurement precision
If full-angle beam scanning is performed to determine optimal beam, then beam accuracy is improved, but time consumption and scanning overhead increase
Solution Approach 1:
The base station acquires obstacle information in advance as a preliminary action, which enables direct determination of the optimal beam without performing time-consuming full-angle scanning. This preliminary information gathering maintains beam accuracy while significantly reducing the time required for beam determination
Solution Approach 2:
The patent extracts only the necessary information (obstacle information and UE position) needed to determine the optimal beam, rather than performing comprehensive full-angle scanning. This extraction approach maintains measurement precision by focusing on critical factors while reducing time consumption by eliminating unnecessary scanning operations
