Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless network technologies face challenges in efficiently managing carrier-specific scaling factors (CSSFs) for user equipment (UE) measurements across different frequency ranges and connectivity modes, particularly in dual connectivity scenarios, leading to suboptimal resource allocation and measurement delays.
Innovation Solution
The implementation of updated CSSF definitions and calculation methods that account for channel state information-reference signal (CSI-RS) and synchronization signal block (SSB) measurements, allowing for dynamic scaling of measurement delays based on specific connectivity modes and frequency bands, enabling efficient resource sharing and measurement reporting across multiple component carriers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If carrier-specific scaling factors are applied to measurements on secondary component carriers in dual connectivity scenarios, then measurement precision is improved, but device complexity increases due to the need to calculate and apply different CSSFs for different frequency ranges and connectivity modes
Solution Approach 1:
The patent segments the measurement process by introducing carrier-specific scaling factors for different frequency ranges (FR1, FR2, FR3) and connectivity modes (SA, NR-DC, E-UTRA-NR DC). Each measurement object is assigned a specific CSSF based on its frequency range and the UE's connectivity mode, allowing precise control over measurement timing without requiring complex global adjustments.
Solution Approach 2:
The patent applies local quality by making the scaling factor specific to each carrier and measurement object rather than applying a uniform scaling factor across all carriers. The CSSF is determined based on the specific frequency range and connectivity mode of each carrier, enabling optimized measurement timing for each local context.
2Adaptability or versatility
If multiple measurement objects are configured across different frequency ranges, then adaptability is improved, but loss of time occurs due to measurement delays in dual connectivity scenarios
Solution Approach 1:
The patent introduces dynamic scaling factors that adjust measurement timing based on the UE's connectivity mode and frequency range. The CSSF can be dynamically determined as 1, 2, or 4 based on whether the UE is in SA mode, NR-DC mode, or E-UTRA-NR DC mode, and on the frequency range of the measurement object, allowing flexible adaptation without fixed delays.
Solution Approach 2:
The patent changes the timing parameter of measurements by applying carrier-specific scaling factors to the measurement period. This allows the measurement timing to be adjusted based on the frequency range and connectivity mode, reducing measurement delays while maintaining adaptability across different scenarios.
3Measurement precision
If carrier-specific scaling factors are calculated for each measurement object, then measurement precision is improved, but productivity decreases due to increased processing overhead
Solution Approach 1:
The patent performs preliminary action by determining the CSSF in advance based on the UE's connectivity mode and the frequency range of the measurement object. The network can pre-configure the appropriate CSSF values, and the UE can determine the CSSF based on predefined rules, avoiding complex real-time calculations and reducing processing overhead.
