Selective Cell Measurement via Type Parameter
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, particularly in LTE, the existing protocols require the same neighbor cell and blacklist cell information to be used for all measurements at the same frequency point, leading to unnecessary interference and complexity, which hinders quick and accurate cell measurement and reporting by UE.
Innovation Solution
Incorporating a measurement object type parameter in measurement control information to allow selective measurement and reporting of neighbor cell and blacklist cell information, enabling UE to distinguish and report only the necessary information based on the measurement object type parameter, thereby reducing unnecessary measurements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the same measurement object is used for all measurements at the same frequency point, then the protocol constraint is satisfied and implementation is simplified, but unnecessary measurements interfere with normal measurements and reduce accuracy
Solution Approach 1:
The patent segments the measurement object into distinct components: neighbor cell information and blacklist cell information. By introducing a measurement object type parameter that can independently control measurement and reporting for each component, the patent enables selective measurement without requiring separate measurement objects for each cell type, thus improving measurement accuracy while maintaining protocol simplicity.
2Productivity
If the same neighbor cell information and blacklist cell information are used for all measurements, then the measurement object constraint is satisfied, but unnecessary measurements increase processing overhead and reduce reporting speed
Solution Approach 1:
The patent applies partial action by allowing the network to selectively enable measurement and reporting for neighbor cells, blacklist cells, both, or neither based on the measurement object type parameter. This enables the UE to perform only the necessary measurements rather than all possible measurements, reducing measurement data volume and improving reporting speed while maintaining protocol compatibility.
3Reliability
If unnecessary measurements are performed, then all possible cell information is collected, but measurement interference increases and measurement quality deteriorates
Solution Approach 1:
The patent extracts the harmful element by introducing a mechanism to selectively exclude unnecessary measurements. The measurement object type parameter enables the network to extract only the relevant cell information (neighbor cells, blacklist cells, both, or neither) needed for specific measurement purposes, thereby eliminating measurement interference from unnecessary cells while maintaining measurement reliability for the required cells.
