UE Connectivity Mode Control for Power Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems lack a method for a communication device to control the addition of a Secondary Cell Group (SCG), leading to inefficient power consumption and resource usage, especially when only small amounts of data are being transferred, as they often enter dual connectivity modes unnecessarily.
Innovation Solution
The introduction of ENDC and NRDC signaling allows a communication device to indicate preferences for using a SCG or remaining in a Master Cell Group (MCG) only, with autonomous IRAT NR measurements and reporting, enabling the device to efficiently manage connectivity based on data transfer needs, thereby optimizing power consumption and resource utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If dual connectivity mode is used to ensure high data throughput, then data transfer capability is improved, but power consumption increases
Solution Approach 1:
The patent implements dynamic connectivity mode selection that adapts between MCG-only and SCG-added configurations based on real-time data transfer requirements. The system transitions from static dual connectivity to dynamic mode switching, enabling the device to use SCG only when high throughput is needed while relying on MCG for low-volume transfers, thus optimizing power consumption across varying workload conditions
Solution Approach 2:
The patent changes the operational parameters of the communication device by introducing a configurable connectivity mode parameter that can switch between two states: MCG-only mode for power saving and SCG-added mode for high performance. This parameter change enables flexible adaptation to different data transfer scenarios, resolving the contradiction between throughput and power consumption
2Productivity
If SCG is added to increase data throughput, then productivity is improved, but device complexity increases
Solution Approach 1:
The patent segments the connectivity management into distinct operational modes (MCG-only and SCG-added) with clear transition criteria. By dividing the complex dual connectivity management into discrete, selectable states with automated mode switching, the system reduces the perceived complexity while maintaining high throughput capability when needed
3Use of energy by moving object
If MCG-only mode is used to reduce power consumption, then energy efficiency is improved, but data throughput is limited
Solution Approach 1:
The system dynamically adjusts connectivity configuration based on real-time data transfer requirements, switching from MCG-only to SCG-added mode when high throughput is detected. This dynamic adaptation ensures that the device operates in power-efficient MCG-only mode during low-volume transfers while automatically escalating to high-performance SCG-added mode when throughput demands increase, thus resolving the throughput limitation

AI summary
Performing autonomous measurements at a user equipment (UE) may include encoding a radio resource control (RRC) connection request for transmission to a first base station having a first base station type. An RRC connection setup communication received from the first base station may be decoded. Measurements associated with a set of candidate carriers of a second base station type may be autonomously performed while in an RRC connected state. Autonomously performing the measurements may including deriving the set of candidate carriers to be measured. Results from the performed measurements may be stored.
