Layer 1 Measurement Sharing for Overlapping FR2 Reference Signals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication technologies face challenges in efficiently managing beam and link management operations in high-frequency ranges like FR2 due to overlapping measurement occasions of reference signals, leading to inefficiencies in determining measurement periods and potential radio-link failures.
Innovation Solution
A method to determine sharing factors for measurement occasions between different reference signals, such as SSBs and MGs, using periodicity relationships and overlapping conditions to optimize L1-RSRP measurement periods, thereby enhancing beam management and reducing the likelihood of radio-link failures.

Engineering Contradiction Analysis
1Measurement precision
If measurement occasions for different reference signals are managed separately, then measurement precision can be maintained, but device complexity and resource overhead increase
Solution Approach 1:
The patent combines the management of measurement occasions for different reference signals (SSB and CSI-RS) by determining whether they overlap in time. When measurement occasions overlap, the patent applies a unified sharing factor calculation that considers both reference signals together rather than managing them separately, thereby reducing device complexity while maintaining measurement precision through coordinated resource allocation.
2Measurement precision
If measurement periods are extended to capture more measurement opportunities, then measurement precision improves, but loss of time for other operations increases
Solution Approach 1:
The patent dynamically adjusts the measurement period and sharing factor based on the periodicity relationship between different reference signals. By calculating the sharing factor as a function of the least common multiple of periodicities and the number of overlapping occasions, the system optimizes measurement precision while minimizing time loss through parameter adaptation rather than fixed extended periods.
3Productivity
If sharing factors are calculated using complex periodicity relationships, then productivity of resource allocation improves, but device complexity increases
Solution Approach 1:
The patent segments the sharing factor calculation into distinct cases based on the periodicity relationship between reference signals. It identifies specific scenarios (e.g., when periodicities are equal, when one is a multiple of the other, when they are unrelated) and applies simplified calculation rules for each segment, thereby improving resource allocation productivity while keeping device complexity manageable through case-based simplification.
