Solution Overview
Problem
In wireless communication systems that support beamforming, there is a challenge in selecting an optimal beam to prevent service disconnection due to obstacles or movement between transmitting and receiving nodes, particularly in real-time services where seamless connectivity is critical.
Innovation Solution
A method and apparatus for adaptively selecting a beam based on the type of service, using a controller to determine the optimal beam and a transceiver to transmit or receive data using the selected beam, which includes a beam cost calculation and priority system to minimize disconnections and ensure continuous service.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If beamforming is used to improve transmission performance in super-high frequency bands, then data transmission rate is improved, but service disconnection occurs when obstacles or movement are detected
Solution Approach 1:
The patent implements dynamic beam selection by switching between first and second beams based on real-time detection of obstacles or movement. The system dynamically adjusts the beam configuration from a fixed first beam to a second beam when disconnection is detected, enabling adaptive response to changing environmental conditions while maintaining high data transmission rates.
Solution Approach 2:
The patent changes the beam parameter (beam direction and configuration) based on service type and environmental conditions. For real-time services, the system uses a second beam with different characteristics than the first beam, adjusting parameters to optimize both transmission rate and continuity under different operational scenarios.
2Productivity
If a single beam is selected for data transmission, then transmission efficiency is improved, but service disconnection occurs when obstacles appear or movement is detected
Solution Approach 1:
The system dynamically switches between multiple beams based on real-time detection. When obstacles or movement are detected in the first beam path, the system transitions to using a second beam, providing dynamic adaptability that maintains both efficiency and continuity without being locked into a single fixed beam configuration.
Solution Approach 2:
The patent employs feedback mechanisms where the receiving node detects obstacles or movement and sends this information back to the transmitting node. This feedback triggers a beam switch from the first beam to the second beam, ensuring continuous service while maintaining transmission efficiency through real-time monitoring and adaptive response.
3Reliability
If beam switching is implemented to prevent disconnection, then service continuity is improved, but system complexity increases
Solution Approach 1:
The patent segments the beam management function into distinct components: a first beam for normal transmission and a second beam for obstacle avoidance. This segmentation allows the system to handle different transmission scenarios with dedicated beam configurations, reducing the complexity of managing multiple dynamic parameters by organizing them into clear functional categories.
Solution Approach 2:
The patent applies different beam qualities and characteristics to different transmission scenarios. The first beam is optimized for normal conditions with high transmission efficiency, while the second beam is optimized for obstacle avoidance with enhanced continuity. This localized optimization of beam properties for specific use cases simplifies the overall system design compared to a single complex beam management approach.
