CSI-RS Mobility Measurement Scaling for Measurement-Gap Conflicts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobility measurement methods for terminals face challenges in determining scaling factors for multiple measurement objects (MOs) due to limited measurement capabilities, particularly in CSI-RS based mobility measurements, where flexibility and specificity in configuring CSI-RS resources are lacking.
Innovation Solution
A method for determining scaling factors in CSI-RS based mobility measurements by considering whether CSI-RS resources coincide with measurement gaps, allowing for flexible configuration and efficient measurement by distinguishing between CSI-RS resources that require gap contention and those that can be measured outside the gap.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple measurement objects are configured for terminal mobility measurement, then measurement coverage is improved, but measurement capability limitations cause measurement completion difficulty
Solution Approach 1:
The patent segments measurement objects into different types (intra-frequency and inter-frequency MOs) and applies different scaling factor determination methods to each type. This segmentation allows the terminal to handle multiple MOs systematically by dividing them into manageable groups with distinct measurement procedures, resolving the contradiction between comprehensive measurement coverage and reliable measurement completion.
2Adaptability or versatility
If CSI-RS resources are configured with high flexibility, then configuration adaptability is improved, but scaling factor determination becomes undeterminable
Solution Approach 1:
The patent introduces specific parameters (scaling factors) that change based on the relationship between CSI-RS resources and measurement gaps. By defining different scaling factor values (e.g., 0.5 or 1.0) based on whether CSI-RS resources coincide with measurement gaps, the patent transforms the flexible but undeterminable configuration into a structured system with clear determination rules, resolving the contradiction between configuration flexibility and measurement determinability.
3Measurement precision
If measurement is performed on all configured MOs, then measurement accuracy is improved, but measurement time and resource consumption increase
Solution Approach 1:
The patent applies partial action by determining scaling factors that allow the terminal to prioritize measurement of certain MOs over others based on their scaling factor values. Instead of uniformly measuring all MOs with equal effort, the terminal can focus measurements on MOs with higher priority (lower scaling factors), achieving acceptable measurement accuracy while reducing overall measurement time and resource consumption.

AI summary
Embodiments of this application disclose a mobility measurement method, an apparatus, and a communication device, and relate to the field of communication technologies, to determine a scaling factor in CSI-RS based mobility measurement, and implement the CSI-RS based mobility measurement. A specific solution is: receiving a first configuration message, where the first configuration message is used to configure a first MO, and the first MO includes one or more CSI-RS resources; and determining a scaling factor of the first MO depending on whether there is a CSI-RS resource in the first MO that completely coincides with a gap, to perform mobility measurement on the first MO.
