5G NR Measurement Gap Configuration for Master-Slave Coordination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 5G NR technology lacks a scheme for coordinating the configuration of measurement gaps between slave base stations and between slave and master base stations, leading to incomplete network communication, reduced reliability, and invalidity of network communication.
Innovation Solution
A measurement gap configuration method is introduced, allowing for the configuration of per-UE, per-CG, and per-CC measurement gaps, enabling coordination between master and slave nodes, and ensuring integrity and reliability of 5G NR network communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If per-UE measurement gap configuration is used, then measurement coordination between master and slave nodes is achieved, but device complexity increases due to multiple configuration levels (per-UE, per-CG, per-CC)
Solution Approach 1:
The measurement gap configuration is segmented into three hierarchical levels: per-UE (user equipment) level, per-CG (cell group) level, and per-CC (component carrier) level. This segmentation allows the system to apply measurement gap configurations at different granularities depending on the specific scenario, enabling coordinated measurement between master and slave nodes while managing complexity through structured organization.
Solution Approach 2:
The patent introduces a hierarchical dimension to the measurement gap configuration by adding the per-CG and per-CC levels above the basic per-UE level. This dimensional expansion allows the system to address coordination requirements between master and slave nodes by configuring measurement gaps at appropriate hierarchical levels, thereby improving reliability without overwhelming complexity.
2Reliability
If measurement gap coordination between master and slave nodes is implemented, then network communication integrity is improved, but the complexity of configuration management increases
Solution Approach 1:
Configuration management is segmented across three levels: per-UE for individual user equipment requirements, per-CG for cell group coordination, and per-CC for component carrier-specific settings. This segmentation enables distributed configuration management where each level handles specific aspects of measurement gap coordination, improving network communication integrity while distributing the management complexity across multiple manageable components.
Solution Approach 2:
The configuration system is designed to be dynamic, allowing the network to select and apply appropriate configuration levels (per-UE, per-CG, or per-CC) based on the specific operational scenario and requirements. This dynamic adaptability enables the system to balance between coordination needs and management complexity by activating only the necessary configuration levels for each situation.
