Solution Overview
Problem
Current wireless communication technologies, such as LTE and NR, face challenges in managing multiple antenna panels efficiently, leading to excessive power utilization and poor network performance due to static configuration and inadequate dynamic adjustment based on link quality.
Innovation Solution
A method and apparatus for dynamically managing multiple antenna panels by transmitting panel configuration messages between user equipment (UE) and base stations (BS), allowing for the activation and deactivation of antenna panels based on link quality, enabling power-saving modes and improved link quality through dynamic panel management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all antenna panels are activated continuously to improve link quality, then communication reliability is improved, but power consumption increases
Solution Approach 1:
The patent implements dynamic antenna panel management where panels are activated or deactivated based on real-time link quality conditions. The system transitions from static continuous activation to dynamic on-demand activation, adjusting the operational state of antenna panels according to communication requirements and environmental conditions.
Solution Approach 2:
The system changes the operational parameters of antenna panels by adjusting their activation state (active/inactive) based on link quality metrics. This parameter change allows the system to optimize between power consumption and link quality by selectively activating only the necessary panels under specific conditions.
2Use of energy by moving object
If antenna panels are deactivated to reduce power consumption, then power utilization is improved, but link quality deteriorates
Solution Approach 1:
The patent employs feedback mechanisms where the system continuously monitors link quality conditions and uses this information to determine whether to activate or deactivate antenna panels. This closed-loop control ensures that panels are deactivated only when link quality permits, preventing deterioration of communication reliability while achieving power savings.
Solution Approach 2:
The system performs preliminary assessment of link quality conditions before deactivating antenna panels. By evaluating current communication requirements and predicting future needs, the system can safely deactivate panels without compromising link quality, thus achieving power utilization improvement.
3Device complexity
If static configuration is used to simplify system management, then device complexity is reduced, but adaptability to changing conditions worsens
Solution Approach 1:
The patent implements self-service mechanisms where the antenna panel management system automatically adjusts its configuration based on monitored link quality conditions without requiring manual intervention. The system independently evaluates conditions and makes activation/deactivation decisions, providing adaptability while maintaining relatively simple overall system architecture.
