NR Dual Connectivity Control to Reduce Power During Low Activity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems with NR technology experience excessive power consumption due to unnecessary SCG additions and frequent NR measurements during minimal or no data activity, Wi-Fi connectivity, or mobile data being turned off, leading to inefficient power management.
Innovation Solution
Implement a network management system within the electronic device to monitor conditions such as no/minimal data activity, Wi-Fi connectivity, or mobile data being off, and automatically release or restrict NR capabilities and measurements to prevent unnecessary SCG additions and power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If NR measurements are performed and SCG is added based on event B1-NR measurement report, then NR dual connectivity capability is improved, but power consumption increases excessively during no/minimal data activity
Solution Approach 1:
The patent implements dynamic adjustment of NR measurement and SCG addition behavior based on device conditions. The network management system monitors data activity levels and Wi-Fi connectivity status, then dynamically enables or disables NR measurement configurations and SCG additions. When no/minimal data activity is detected or Wi-Fi is connected, the system disables NR measurements and prevents SCG addition, thereby reducing power consumption while maintaining NR dual connectivity capability when needed.
2Reliability
If SCG is added based on event B1-NR measurement report during no/minimal data activity, then NR service coverage is improved, but unnecessary power consumption occurs
Solution Approach 1:
The patent employs feedback mechanisms where the network management system continuously monitors device conditions including data activity levels and Wi-Fi connectivity. Based on this feedback, the system adjusts NR measurement and SCG addition behavior. When feedback indicates no/minimal data activity or Wi-Fi connection, the system provides feedback to the base station to disable NR measurements and prevent SCG addition, eliminating unnecessary power consumption while maintaining service coverage availability when conditions change.
3Adaptability or versatility
If NR measurements are configured during VoLTE call with no/minimal data activity, then inter-RAT measurement capability is improved, but power consumption increases
Solution Approach 1:
The patent implements dynamic control of inter-RAT measurement configurations during VoLTE calls. The network management system monitors data activity levels and dynamically adjusts measurement configurations based on current conditions. When no/minimal data activity is detected during a VoLTE call, the system disables NR measurement configurations, preventing the device from performing power-consuming inter-RAT measurements while maintaining the capability to enable them when data activity increases.
