Aerial UE Measurement Reporting With Counter-Based Cell Triggers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aerial UEs detect a larger number of neighbor cells due to fewer obstructions, requiring enhanced measurement report triggering mechanisms to manage mobility efficiently while conserving power and processing resources.
Innovation Solution
Implement a counter-based mechanism for aerial UEs to transmit measurement reports when a pre-configured number of neighbor cells meet specific signal strength conditions, using timers and thresholds to manage inclusion and exclusion of cells in the report.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a legacy measurement report triggering mechanism is used for aerial UEs, then the UE can detect and report neighbor cells, but the number of reported cells becomes excessively large leading to increased processing capability and power consumption
Solution Approach 1:
The patent changes the triggering parameters by introducing a counter-based mechanism where measurement reports are triggered after a predetermined number of times that signal strength conditions are met, rather than triggering on every condition fulfillment. This parameter change reduces the frequency of reporting while maintaining detection accuracy.
Solution Approach 2:
The patent implements periodic reporting by requiring the signal strength condition to be met a predetermined number of times before triggering a measurement report. This periodic action filters out transient fluctuations and reduces unnecessary reporting, thereby conserving power.
2Measurement precision
If a legacy measurement report triggering mechanism is used for aerial UEs, then the UE can detect neighbor cells, but the processing capability requirement increases due to the large number of detected cells
Solution Approach 1:
The patent modifies the triggering parameters by implementing a counter mechanism that requires a predetermined number of condition fulfillments before reporting. This parameter change reduces the volume of data that needs to be processed and reported, thereby reducing processing capability requirements.
Solution Approach 2:
The patent extracts only the most significant measurement information by using a counter-based triggering mechanism that filters out transient or insignificant cell detections. This extraction approach reduces the amount of data that needs to be processed and reported.
3Use of energy by moving object
If the number of reported neighbor cells is reduced to save power, then power consumption decreases, but the network equipment cannot learn the wireless environment thoroughly
Solution Approach 1:
The patent changes the triggering parameter from immediate reporting to counter-based reporting, where a predetermined number of condition fulfillments are required. This parameter change ensures that only stable and significant cell detections are reported, maintaining information quality while reducing power consumption.
Solution Approach 2:
The patent implements a feedback mechanism through the counter, where the system continuously monitors signal strength conditions and only triggers reporting when the condition is met a predetermined number of times. This feedback approach ensures that reported information is reliable and representative of the actual wireless environment.

AI summary
Method and apparatus for measurement report triggering are disclosed. One method of UE such as aerial vehicles includes determining whether to transmit a measurement report according to a counter for a number of the neighbor cells with signal strength fulfilling a condition indicated by a network equipment; and transmitting the measurement report to the network equipment including information of the neighbor cells, in the case that the counter is larger than or equal with a threshold.
