CPE State Management for HAPS Power and Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Customer premises equipment (CPE) for high altitude platform stations (HAPS) face issues of high power consumption and low resource utilization due to dynamic traffic patterns and interference with terrestrial cellular systems, necessitating an efficient state management system.
Innovation Solution
The CPE is equipped with a receiving unit for traffic and configuration information, allowing a control unit to dynamically switch between on and off states, including full off and semi-off states, to optimize resource utilization and power consumption based on real-time traffic loads and configuration instructions from the HAPS.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the CPE operates in an on state to handle user traffic, then communication service is provided, but power consumption increases and resource utilization decreases
Solution Approach 1:
The CPE dynamically switches between on state, semi-off state, and full off state based on traffic load conditions. The control unit determines state transitions by monitoring traffic load information and configuration information, enabling the system to adapt its operational state to current demand and minimize power consumption while maintaining service availability when needed.
Solution Approach 2:
The patent changes the operational parameters of the CPE by introducing multiple discrete states (on, semi-off, full off) with different levels of functionality. Each state corresponds to different power consumption levels and service capabilities, allowing the system to optimize the balance between power usage and service availability by selecting appropriate states based on traffic conditions.
2Speed
If the CPE operates continuously to respond to traffic changes, then service responsiveness is improved, but resource utilization rate decreases
Solution Approach 1:
In the semi-off state, the CPE periodically transmits reference signals at predetermined time intervals to detect traffic load changes. This periodic operation allows the system to maintain一定的 responsiveness to traffic changes while consuming less power and utilizing resources more efficiently compared to continuous operation. The control unit monitors these periodic signals and transitions to on state when traffic load exceeds thresholds.
3Measurement precision
If the CPE transmits reference signals frequently to detect traffic load, then traffic load detection accuracy is improved, but power consumption increases
Solution Approach 1:
The CPE transmits reference signals periodically at predetermined time intervals rather than continuously or on-demand. This periodic transmission provides sufficient traffic load detection capability while significantly reducing power consumption compared to frequent or continuous signal transmission. The period is configured to balance detection accuracy with energy savings.
4Use of energy by moving object
If the CPE operates in full off state to minimize power consumption, then power saving is maximized, but service responsiveness decreases
Solution Approach 1:
The CPE performs preliminary monitoring and evaluation of traffic load conditions even in full off state or semi-off state. When traffic load exceeds predetermined thresholds, the system is prepared to quickly transition to on state. This preliminary preparation reduces the effective service activation time while maintaining power savings during low-traffic periods.
