Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G communication systems, determining the azimuth of antenna modules in base stations accurately is challenging due to errors in initial measurement and registration, affecting the normal operation and coverage area of the base stations.
Innovation Solution
A method and apparatus that receive per-terminal location and signal strength information from multiple terminals, sample terminals within the coverage area, and determine the azimuth for transmission based on this data, allowing for the identification of antenna-specific azimuths and assessment of base station operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If initial measurement and registration methods are used to determine antenna module azimuth, then the determination process is simple, but measurement precision is low due to errors affecting normal operation and coverage area
Solution Approach 1:
The system collects actual terminal location information and received signal strength from multiple terminals, compares this feedback data with the initially registered azimuth information, and adjusts the antenna module azimuth to correct measurement errors. This closed-loop feedback mechanism improves azimuth determination accuracy by using real-world operational data to validate and correct initial measurements.
Solution Approach 2:
The patent replaces traditional mechanical or manual azimuth measurement methods with a signal-based electronic determination system. By using received signal strength measurements from multiple terminals and processing this data through a controller, the system electronically determines and adjusts azimuth without relying on initial mechanical measurements, thereby improving precision.
2Reliability
If traditional azimuth determination methods are used, then the system operation is simple, but reliability is reduced due to errors in initial measurements affecting coverage area
Solution Approach 1:
The base station system performs self-diagnosis and self-correction by using its own transmitted signals and the feedback from terminals to automatically detect azimuth errors and adjust its antenna module orientation. This self-service capability improves reliability by enabling the system to correct its own measurement errors without external intervention, ensuring normal operation and coverage area maintenance.
Solution Approach 2:
The patent introduces terminal devices as intermediaries to verify and validate the base station's azimuth information. Terminals provide independent measurements of signal strength and location, serving as external validators that help the base station confirm or correct its azimuth determination, thereby improving operational reliability through third-party verification.
3Measurement precision
If detailed sampling of terminals is performed to improve azimuth accuracy, then measurement precision improves, but loss of time increases due to extensive data collection and processing
Solution Approach 1:
The system performs partial sampling by selecting a representative subset of terminals rather than collecting data from all terminals in the coverage area. By using a carefully chosen sample of terminals that adequately represents the coverage region, the system achieves sufficient azimuth determination accuracy without the time cost of exhaustive data collection from every terminal.
Solution Approach 2:
The base station performs preliminary azimuth determination using initially registered information before conducting detailed terminal sampling. This preliminary action provides a starting point that narrows the search range, allowing subsequent detailed measurements to focus on correcting specific errors rather than determining azimuth from scratch, thereby reducing overall processing time while maintaining accuracy.
