Deactivated SCG Measurement Configuration for MR-DC
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current multiple-radio dual connectivity (MR-DC) systems face challenges in configuring and performing measurements for a deactivated secondary cell group (SCG), leading to increased power consumption and reduced data throughput due to the inability to distinguish between activated and deactivated SCG measurement configurations.
Innovation Solution
The implementation of a method that allows user equipment (UE) to obtain and perform measurements using a specific measurement configuration subset or cycle for deactivated SCG mode, which includes a fixed or relaxed measurement configuration, reducing the number of measurements and measurement gaps, and prioritizing radio link quality for efficient power management and data throughput.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If measurement configuration is maintained for deactivated SCG to ensure radio link quality, then reliability is improved, but power consumption increases
Solution Approach 1:
The measurement configuration is segmented into two distinct subsets: one for activated SCG and another for deactivated SCG. This segmentation allows the UE to perform different measurement activities depending on the SCG state, performing comprehensive measurements when activated and reduced measurements when deactivated, thus resolving the contradiction between maintaining reliability and reducing power consumption.
Solution Approach 2:
The measurement configuration is made dynamic by adapting it to the SCG's operational state. The network can configure different measurement parameters, cycles, and gaps based on whether the SCG is activated or deactivated. This dynamic adjustment allows the system to maintain necessary radio link monitoring while minimizing unnecessary measurements that consume battery power.
2Measurement precision
If comprehensive measurement configuration is used for activated SCG, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The measurement configuration is divided into separate subsets for activated and deactivated SCG states. Each subset contains only the measurements necessary for that specific state, reducing the overall complexity the UE must manage while maintaining measurement precision when needed.
Solution Approach 2:
Different measurement configurations are applied locally to different SCG states. The activated SCG receives a comprehensive measurement configuration for high precision, while the deactivated SCG receives a simplified configuration. This local differentiation optimizes measurement quality where needed while reducing complexity overall.
