Measurement Gap Sharing for L1/L2 and L3 Mobility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for techniques that enable user equipment (UE) to implement measurement gap sharing for Layer 3 (L3) based mobility and Layer 1 (L1)/Layer 2 (L2) based mobility, as existing technologies do not effectively address the sharing of measurement gaps across these different mobility types.
Innovation Solution
The UE is configured to determine a measurement gap sharing scheme for L1/L2 based mobility and L3 based mobility, determine a measurement gap pattern that includes both L1/L2 and L3 measurement occasions, and collect measurement data during the measurement gap in accordance with the sharing scheme.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the UE performs separate measurements for L3 based mobility and L1/L2 based mobility, then measurement accuracy is maintained, but measurement time and resource consumption increase
Solution Approach 1:
The patent combines L3 based mobility measurements and L1/L2 based mobility measurements into a single shared measurement gap. The UE performs both types of measurements during the same measurement occasion, merging previously separate measurement procedures into one unified process, thereby reducing measurement time while maintaining accuracy.
Solution Approach 2:
The measurement gap is designed to serve multiple functions simultaneously - it supports both L3 based mobility measurements and L1/L2 based mobility measurements. This multi-functional measurement gap allows the UE to conduct different types of mobility measurements during the same time period, improving resource utilization and reducing overall measurement time.
2Reliability
If the UE uses separate measurement gaps for L3 based mobility and L1/L2 based mobility, then measurement reliability is ensured, but device complexity and resource allocation increase
Solution Approach 1:
The patent merges the configuration of separate measurement gaps into a single shared measurement gap configuration. The network configures one measurement gap that the UE uses for both L3 based mobility and L1/L2 based mobility, simplifying the configuration process and reducing device complexity while maintaining measurement reliability through proper resource allocation within the shared gap.
3Productivity
If the UE performs measurements for multiple mobility types during the same measurement gap, then resource efficiency improves, but measurement precision may deteriorate
Solution Approach 1:
The patent applies local quality by allocating specific measurement resources within the shared measurement gap to different measurement types based on their specific requirements. Different frequencies, reference signals, or time resources within the measurement gap are optimized for specific measurement types, ensuring each measurement maintains its required precision while sharing the overall measurement gap resource.

AI summary
A user equipment (UE) is configured to perform layer 1 (L1), layer 2 (L2) and layer (3) mobility operations. The UE determines a measurement gap sharing scheme for layer 1 (L1)/layer 2 (L2) based mobility and layer 3 (L3) based mobility, determines a measurement gap pattern, wherein at least one measurement gap includes L1/L2 measurement occasions and L3 measurement occasions and collects measurement data during the at least one measurement gap in accordance with the measurement gap sharing scheme.
