Neighbor Cell Measurement Reporting Without Layer 3 Delay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing process of user equipment (UE) measuring and reporting reference signals of neighboring cells involves a long delay due to layer 3 filtering, which is not conducive to mobility management such as cell handover.
Innovation Solution
The UE performs layer 1 measurements on target reference signals of neighboring cells and reports the results directly to the network side device, bypassing the layer 3 filtering process to reduce delay.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If layer 3 filtering is performed on measurement results, then measurement accuracy is improved, but reporting delay increases
Solution Approach 1:
The patent segments the measurement reporting process into two independent paths: layer 1 measurement results are processed and reported separately from layer 3 filtered results. This allows the system to obtain measurement data without waiting for the complete layer 3 filtering process, thereby reducing reporting delay while maintaining the option to use filtered results for accuracy-critical decisions.
Solution Approach 2:
The patent performs preliminary measurement and reporting at layer 1 before the layer 3 filtering process is completed. By reporting measurement results at an earlier stage (layer 1) rather than waiting for the final layer 3 processed results, the system reduces the overall reporting delay while still allowing layer 3 filtered results to be used when high accuracy is required.
2Stability of the object's composition
If layer 3 filtering is applied to measurement results, then short-term fluctuations are reduced, but handover responsiveness deteriorates
Solution Approach 1:
The patent divides the measurement reporting mechanism into multiple layers (layer 1 and layer 3) that can operate independently. Layer 1 provides rapid, fluctuation-prone measurements for quick responsiveness, while layer 3 provides filtered, stable measurements for confirmation. This segmentation allows the system to prioritize speed when necessary while maintaining stability options.
Solution Approach 2:
The patent applies partial filtering by allowing the system to use layer 1 measurement results (without full layer 3 filtering) for time-critical handover decisions. This partial action approach provides sufficient responsiveness for mobile scenarios while reserving the option to apply complete layer 3 filtering when stability is prioritized over speed.
3Reliability
If layer 3 measurement reporting is used, then measurement reliability is improved, but mobility management efficiency deteriorates
Solution Approach 1:
The patent segments the measurement reporting into multiple reliability levels: layer 1 reporting provides rapid but less reliable measurements, while layer 3 reporting provides more reliable but slower measurements. By having both segments available, the system can choose the appropriate reliability level based on the mobility management scenario, thereby improving overall efficiency without completely sacrificing reliability.
Solution Approach 2:
The patent performs preliminary measurement and reporting at layer 1 to enable fast mobility decisions, then optionally supplements or confirms these decisions with layer 3 filtered results. This preliminary action approach improves mobility management efficiency by not waiting for complete layer 3 processing, while still maintaining the ability to use reliable layer 3 results when needed.

AI summary
This application discloses a measurement reporting method and apparatus, and a device. The method includes: performing, by UE, measurement on a target reference signal of a target neighboring cell of a first cell at a layer 1 to obtain a first measurement result; and reporting, by the UE, a target measurement report to a network side device through the layer 1. The target measurement report includes the first measurement result.
