Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In dual connectivity scenarios, existing technologies face challenges in efficiently configuring measurement gaps for wireless devices operating across multiple frequency ranges and radio access technologies, leading to network congestion and increased power consumption due to redundant measurements.
Innovation Solution
A method for configuring measurement gaps in dual connectivity configurations, where a master node manages measurement gap configurations for both frequency ranges, allowing wireless devices to measure both FR1 and FR2, and coordinating with secondary nodes to ensure proper configuration and minimize redundant measurements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If both MN and SN independently configure measurement gaps for a UE, then measurement coverage is improved, but network congestion and power consumption increase due to redundant measurements
Solution Approach 1:
The master node acts as an intermediary that centralizes measurement gap configuration. Instead of both MN and SN independently configuring measurements, the MN manages the measurement gap configuration for the UE while coordinating with the SN, eliminating redundant measurements and reducing power consumption while maintaining comprehensive measurement coverage
Solution Approach 2:
The master node assumes a universal role in managing measurement gap configuration for both FR1 and FR2 frequency ranges. By consolidating this function at the MN level, the system avoids duplicate measurement configurations from multiple nodes, thereby reducing network congestion and UE power consumption while preserving full measurement capability
2Measurement precision
If both MN and SN independently configure measurement gaps for a UE, then measurement coverage is improved, but network congestion increases
Solution Approach 1:
The master node serves as a central coordinator that manages measurement gap configuration for the UE. By consolidating configuration authority at the MN level and coordinating with the SN, the system eliminates duplicate measurement commands in the network, reducing signaling overhead and network congestion while maintaining comprehensive measurement coverage
Solution Approach 2:
The measurement gap configuration function is merged into a single management entity (the master node) that handles both FR1 and FR2 measurements. This consolidation combines what were previously separate independent configuration processes into one unified approach, reducing the quantity of configuration signaling and eliminating redundant measurements
3Measurement precision
If separate measurement gap configurations are provided for FR1 and FR2, then measurement accuracy is improved, but device complexity increases
Solution Approach 1:
The measurement configuration is segmented by frequency range, with the master node providing separate measurement gap configurations for FR1 and FR2. This segmentation allows the UE to maintain accurate measurements for each frequency range while the network manages the complexity of coordinating these separate configurations, preventing the UE from having to independently manage multiple complex configuration sets
