Adapting Active Beam Parameters for Wireless Power Saving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication technologies, such as LTE and 5G, face challenges in efficiently managing active beams, leading to increased power consumption and reduced performance due to the fixed number of active beams, which is not optimized for varying traffic conditions.
Innovation Solution
The method involves adapting the number of active beams by adjusting parameters such as the maximum number of active beams, transmitter-receiver points, and operation modes, allowing the user equipment (UE) to dynamically change these settings based on traffic demand and capability, thereby optimizing power usage and performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the number of active beams is increased to improve communication performance and reliability, then communication reliability and throughput are improved, but power consumption increases
Solution Approach 1:
The patent applies dynamics by making the number of active beams adjustable rather than fixed. The system dynamically adapts the beam configuration based on real-time traffic conditions, switching between different numbers of active beams (e.g., 1 beam for low traffic, multiple beams for high traffic) to optimize the balance between communication reliability and power consumption.
Solution Approach 2:
The patent changes the parameter of active beam number from a static configuration to a dynamic one. By modifying this key parameter based on traffic demand, the system can reduce power consumption during low-activity periods while maintaining high reliability during peak demand, thus resolving the contradiction between these two opposing requirements.
2Ease of operation
If the number of active beams is fixed to simplify device operation, then ease of operation is improved, but adaptability to varying traffic conditions deteriorates
Solution Approach 1:
The patent implements self-service by enabling the system to automatically adjust the number of active beams based on detected traffic conditions without requiring manual intervention. The UE autonomously monitors traffic patterns and configures appropriate beam numbers, maintaining ease of operation while achieving high adaptability to varying network conditions.
Solution Approach 2:
The system transitions from a static fixed configuration to a dynamic adaptive configuration. The number of active beams is continuously adjusted based on real-time traffic conditions, allowing the system to adapt to varying demands while maintaining user-friendly operation through automated management.
3Loss of energy
If the number of active beams is reduced to save power, then power consumption is reduced, but communication throughput decreases
Solution Approach 1:
The patent applies dynamics by implementing flexible, real-time adjustment of active beam numbers. The system can reduce beam count during low-traffic periods to minimize power consumption while automatically increasing it during high-traffic periods to maintain throughput, thus dynamically optimizing the trade-off between energy efficiency and communication performance.
Solution Approach 2:
The system changes the operational parameter of active beam number based on traffic conditions. By adjusting this parameter up or down as needed, the system can reduce power consumption when throughput requirements are low while ensuring sufficient throughput capacity when demand increases, resolving the contradiction between energy saving and productivity.
