Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G wireless communication systems, beam management for multi-module devices faces challenges in optimizing multiple criteria simultaneously, such as throughput, signal quality, module sweeping rate, and module switching rate, leading to conflicts and increased operational costs like power consumption and latency.
Innovation Solution
The implementation of a method and apparatus that dynamically optimize beam management parameters by determining multiple objectives and selecting appropriate parameters to achieve a balance between these criteria, using strategies like data-driven approaches, lookup tables, and machine learning models to manage antenna modules effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If beam management optimizes for high throughput, then data transmission rate is improved, but power consumption increases
Solution Approach 1:
The patent implements dynamic beam management parameters that adapt to changing conditions. The system dynamically adjusts beam sweeping rates, beam switching rates, and other parameters based on current channel conditions, device mobility, and traffic requirements. This dynamic approach allows the system to optimize throughput when conditions permit while reducing power consumption when conditions change, resolving the contradiction between maintaining high throughput and minimizing energy usage.
Solution Approach 2:
The patent changes physical and operational parameters of the beam management system based on multiple objectives. By adjusting parameters such as beam sweeping period, beam switching threshold, and antenna module activation states, the system can shift between throughput-optimized and power-efficient operating modes, effectively resolving the contradiction between these two opposing requirements.
2Reliability
If beam management performs frequent antenna module sweeping to maintain signal quality, then reliability is improved, but latency increases
Solution Approach 1:
The patent applies partial sweeping strategies where the system performs beam management operations on only some antenna modules at given times rather than sweeping all modules frequently. By selectively activating and managing subsets of antenna modules based on current needs, the system maintains adequate signal quality while reducing the overall time spent on sweeping operations, thus lowering latency.
Solution Approach 2:
The patent implements periodic beam management with variable periods. Instead of continuous or uniformly frequent sweeping, the system performs sweeping operations at optimized intervals based on channel stability, device mobility, and signal quality thresholds. This periodic approach with adaptive timing maintains reliability while minimizing unnecessary time loss.
3Productivity
If beam management uses multiple antenna modules simultaneously to increase throughput, then productivity is improved, but device complexity increases
Solution Approach 1:
The patent segments the beam management process into distinct, manageable components. Each antenna module is managed semi-independently with its own activation, deactivation, and sweeping schedule. This segmentation allows multiple modules to operate simultaneously for increased throughput while keeping the control logic for each module relatively simple and modular, reducing overall system complexity.
Solution Approach 2:
The patent creates a universal beam management framework that handles multiple antenna modules using the same core algorithms and procedures. The same beam sweeping, signal quality measurement, and parameter adjustment mechanisms are applied across all antenna modules, providing multi-functionality that increases throughput without proportionally increasing complexity.
