Dynamic Antenna Sampling Rate Adjustment for Handover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies for obtaining signal measurements at user devices in mobile communications environments lack efficiency in determining when and how to adjust sampling rates based on handover conditions, leading to potential inaccuracies in handover decisions and increased power consumption.
Innovation Solution
An apparatus and method that dynamically adjust the sampling rates of antenna panels in user devices based on conditions related to the probability of an inbound handover. This involves determining whether specific conditions are met, such as differences in signal measurements between serving and target cells, and adjusting the sampling rates accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If high sampling rates are used for all antenna panels, then measurement precision is improved, but power consumption increases
Solution Approach 1:
The patent applies dynamics by making the sampling rate adjustable rather than fixed. The sampling rate is dynamically changed based on handover conditions - using high sampling rates when handover is likely and low sampling rates when handover is unlikely, thereby adapting the measurement precision to the actual operational needs and reducing unnecessary power consumption.
Solution Approach 2:
The patent changes the sampling rate parameter based on detected handover conditions. By monitoring signal measurements and determining handover likelihood, the system adjusts the sampling rate parameter between high and low values, optimizing the balance between measurement precision and power consumption according to real-time operational context.
2Use of energy by moving object
If low sampling rates are used for all antenna panels, then power consumption is reduced, but measurement precision deteriorates
Solution Approach 1:
The system dynamically adjusts sampling rates based on handover conditions rather than using a fixed low sampling rate. When handover conditions are detected, the sampling rate is increased to maintain measurement precision, while during normal operation, lower sampling rates are used to conserve power.
Solution Approach 2:
The sampling rate parameter is changed based on operational conditions. The system transitions between low sampling rates (for power saving) and high sampling rates (for measurement accuracy) by detecting handover-related signal conditions, ensuring precision is maintained only when necessary.
3Measurement precision
If high sampling rates are used for all antenna panels, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent applies local quality by differentiating the sampling rate treatment for different antenna panels based on their specific handover conditions. Instead of uniformly applying high sampling rates to all panels, the system identifies which panels are relevant to handover decisions and adjusts their sampling rates individually, reducing overall device complexity while maintaining necessary measurement precision.
Solution Approach 2:
The sampling rate parameter is selectively changed for specific antenna panels based on handover conditions rather than uniformly across all panels. This conditional parameter adjustment reduces the complexity of controlling all panels at high sampling rates while maintaining measurement precision where needed.
4Device complexity
If low sampling rates are used for all antenna panels, then device complexity is reduced, but measurement precision deteriorates
Solution Approach 1:
The system dynamically adjusts sampling rates based on detected handover conditions. When handover conditions are present, the sampling rate is increased for relevant antenna panels to maintain measurement precision, while avoiding the complexity of continuously operating all panels at high sampling rates.
5Use of energy by moving object
If sampling rates are adjusted based on handover conditions, then power consumption is reduced, but handover decision accuracy may deteriorate
Solution Approach 1:
The patent applies preliminary action by proactively increasing sampling rates when handover conditions are detected, ensuring measurement precision is maintained at the critical moment of handover decision-making. The system anticipates the need for accurate measurements by adjusting sampling rates in advance of the actual handover execution.
Solution Approach 2:
The system uses feedback from signal measurement analysis to determine handover likelihood and adjust sampling rates accordingly. By continuously monitoring signal conditions and using this feedback to control sampling rate adjustments, the system ensures that measurement accuracy is maintained when needed while reducing power consumption during normal operation.
