Dual-Condition Measurement Reporting for Early Sync and Cell Switch
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing event triggered measurement reporting procedures in 5G NR do not effectively manage early synchronization and cell switch decisions, leading to inefficient radio resource utilization and increased complexity in LTM operations.
Innovation Solution
Implement a dual-condition event triggered measurement reporting procedure, where separate conditions are configured for early synchronization and cell switch, allowing timely early synchronization without unnecessary reporting and optimizing resource use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single event triggered measurement reporting procedure is used for both early synchronization and cell switch, then the procedure is simple to implement, but it leads to inefficient radio resource utilization and increased complexity in LTM operations
Solution Approach 1:
The patent divides the single measurement reporting procedure into two separate conditional procedures: one for early synchronization (when beam quality improves above a threshold) and one for cell switch (when cell quality improves above a threshold). This segmentation allows each procedure to be optimized independently, reducing overall system complexity while maintaining ease of implementation through clear, distinct triggering conditions.
2Ease of manufacture
If event triggered measurement reporting is performed without separate conditions for early synchronization and cell switch, then the implementation is straightforward, but radio resource occupancy increases due to unnecessary reporting
Solution Approach 1:
The patent applies different quality thresholds and evaluation criteria locally to different scenarios: early synchronization uses beam-quality thresholds for triggering, while cell switch uses cell-quality thresholds. This local differentiation ensures that measurement reporting is triggered only when appropriate for each specific scenario, preventing unnecessary reporting and optimizing radio resource utilization while keeping the implementation straightforward.
3Productivity
If separate conditions are configured for early synchronization and cell switch measurement reporting, then radio resource utilization is optimized, but the configuration complexity increases
Solution Approach 1:
The patent creates a universal measurement reporting framework that handles both early synchronization and cell switch scenarios through a common configuration structure. The base station configures measurement objects, reporting configurations, and event thresholds that can be applied to both purposes, reducing configuration complexity while maintaining optimized resource utilization through scenario-specific triggering conditions.

AI summary
The present disclosure relates to a user equipment, UE, comprising the following. A transceiver of the UE, in operation, receives from a base station, a configuration for event triggered measurement reporting. A processing circuitry of the UE, in operation, obtains, from the event triggered measurement reporting configuration, a first condition for triggering early synchronization measurement reporting, which is performed in preparation of an early synchronization with a target candidate beam, and a second condition, which differs from the first condition, for triggering cell switch measurement reporting which is performed in preparation of a cell switch with a target candidate cell, and (is configured to) performs, for one or more beams, an evaluation as to whether measurements on the one or more beams fulfil at least one of the first condition and of the second condition. Further, there are provided a base station and methods performed by the UE or the base station.
