Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems lack effective methods for event triggered measurement logging to determine radio access technology (RAT)-specific and frequency-specific coverage holes, which are crucial for optimizing network performance and user equipment (UE) connectivity.
Innovation Solution
A method and apparatus for user equipment (UE) to receive a logged measurement configuration from a network entity, defining events for event triggered measurement logging associated with RAT-specific or frequency-specific coverage holes, enabling measurement logging based on the occurrence of these events, regardless of the UE's camped radio access technology.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If event triggered measurement logging is implemented for RAT-specific and frequency-specific coverage holes, then measurement precision and network optimization capability are improved, but device complexity and processing requirements increase
Solution Approach 1:
The measurement logging function is segmented into distinct event types (RAT-specific coverage hole events and frequency-specific coverage hole events), allowing the system to handle different measurement scenarios separately. This segmentation enables precise detection of coverage holes while managing complexity through modular event handling structures.
Solution Approach 2:
The network entity pre-configures the UE with measurement logging configurations including event definitions, measurement objects, and reporting parameters before the UE enters coverage hole scenarios. This preliminary configuration reduces real-time processing complexity by establishing measurement criteria and logging parameters in advance.
2Productivity
If comprehensive measurement logging is performed for all event types, then network performance optimization is improved, but energy consumption and processing load increase
Solution Approach 1:
Measurement logging is activated periodically based on event triggers rather than continuously. The UE monitors for specific coverage hole events and activates detailed logging only when these events occur, reducing overall energy consumption while maintaining network optimization capability when needed.
Solution Approach 2:
The measurement logging applies different quality levels to different scenarios: comprehensive logging is performed only when coverage hole events are detected, while normal operation uses reduced monitoring. This local quality approach optimizes energy usage by concentrating detailed measurements where network optimization is most beneficial.
3Adaptability or versatility
If measurement logging is performed regardless of camped RAT, then adaptability and coverage hole detection capability are improved, but device complexity and configuration management difficulty increase
Solution Approach 1:
The measurement logging configuration is designed to be universally applicable across multiple RATs (LTE, NR, etc.). The same logging framework and event definitions work regardless of which RAT the UE is currently camped on, providing adaptability while the network entity manages the complexity of RAT-specific parameters centrally.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network entity, a logged measurement configuration that defines an event for event triggered measurement logging, wherein the event is associated with a radio access technology (RAT)-specific coverage hole or a frequency specific coverage hole. The UE may perform, based at least in part on the logged measurement configuration, measurement logging based at least in part on an occurrence of the event associated with the RAT-specific coverage hole or the frequency specific coverage hole. Numerous other aspects are described.
