Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Designing a standard process for smart antennas to automatically select the best beam for wireless communication is challenging, as existing methods lack efficiency in managing communication quality and power amplifier saturation.
Innovation Solution
An antenna control method that scans multiple beams, compares communication quality parameters like RSRP, RSRQ, and SINR, selects the best beam, and switches to an adjacent beam when the main beam causes power amplifier saturation, using moving average calculations and threshold comparisons to determine saturation and strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the antenna device uses multiple beams for communication, then the communication quality can be improved, but the complexity of beam management and selection increases
Solution Approach 1:
The antenna device automatically performs beam scanning, quality parameter measurement, and best beam selection without external intervention. The system self-manages the beam switching process by continuously monitoring communication quality parameters and autonomously determining the optimal beam, thereby improving communication reliability while keeping the control process manageable
Solution Approach 2:
The system continuously measures communication quality parameters (RSRP, RSRQ, SINR) for each beam and uses this feedback information to determine the best beam. The feedback mechanism enables automatic beam selection and switching, allowing the system to adapt to changing communication conditions while maintaining manageable complexity through algorithmic decision-making
2Productivity
If the main communication beam is selected based on best communication quality, then communication efficiency is improved, but power amplifier saturation may occur
Solution Approach 1:
The system performs a scanning process on all candidate beams before selecting the main communication beam. During this preliminary scanning phase, the communication quality parameters of each beam are measured and compared. This preliminary action allows the system to identify potential saturation issues and select an appropriate beam in advance, preventing power amplifier saturation while maintaining communication efficiency
Solution Approach 2:
The system proactively monitors communication quality parameters to detect conditions that may lead to power amplifier saturation. By identifying these conditions in advance through parameter comparison and threshold evaluation, the system can switch to an alternative beam before saturation occurs, thereby preventing the harmful effect while maintaining efficient communication
3Reliability
If beam switching is performed frequently to maintain communication quality, then communication reliability is improved, but network disconnections increase
Solution Approach 1:
The system dynamically adjusts the beam selection based on real-time communication quality parameters. Instead of fixed beam assignment, the system continuously monitors parameters such as RSRP, RSRQ, and SINR, and switches beams only when necessary to maintain communication quality. This dynamic approach improves reliability while minimizing unnecessary switching that could cause disconnections
Solution Approach 2:
The system performs periodic beam scanning and quality parameter measurements at defined intervals. This periodic action allows the system to maintain communication reliability by regularly assessing beam performance while avoiding excessive switching. The periodic nature of the scanning process ensures that beam switching occurs only when communication quality degrades below acceptable thresholds, thereby reducing unnecessary disconnections

AI summary
An antenna control method for controlling an antenna device to switch between a plurality of beams. The antenna control method includes the steps of: (a) using the beams for communication one after another, and performing a scanning process on each of the beams, so as to retrieve a communication quality parameter; (b) comparing all of the communication quality parameters with each other, and selecting one of the beams as a main communication beam, wherein the selected beam has the best communication quality parameter; (c) performing a saturation determination process on the main communication beam; and (d) when the main communication beam causes saturation of a power amplifier, switching to another beam which is adjacent to the main communication beam as a substitute communication beam.
