Terminal Device SCG Failure Reporting for Power Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the Dual Connectivity architecture of the New Radio (NR) system, terminal devices experience high power consumption and short battery life due to the need to maintain connections with both LTE and NR networks simultaneously.
Innovation Solution
A measurement reporting method where the terminal device transmits Secondary Cell Group (SCG) failure information with no measurement result for the NR network, allowing it to establish a connection only through the LTE network without reporting NR network measurements, thereby conserving power and prolonging battery life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the terminal device establishes a connection with both LTE and NR networks in Dual Connectivity mode, then the network coverage and data transmission capability are improved, but the power consumption increases and battery life decreases
Solution Approach 1:
The patent applies dynamics by enabling the terminal device to dynamically switch between different connection modes (single network mode and dual connectivity mode) based on real-time network conditions and user needs. The terminal can transition from maintaining both LTE and NR connections to establishing connections with only one network, thereby dynamically adjusting power consumption levels while preserving network coverage adaptability.
Solution Approach 2:
The patent changes the connection mode parameter from dual connectivity to single network mode by utilizing measurement reports and network conditions. When the terminal determines that dual connectivity is not necessary (e.g., when measurement reports indicate no need for SCG addition), it changes the connection configuration to reduce power consumption while maintaining adequate network coverage through the remaining network connection.
2Productivity
If the terminal device maintains Dual Connectivity with both LTE and NR networks, then the data transmission capability is improved, but the battery life is reduced
Solution Approach 1:
The patent implements dynamics by allowing the terminal to dynamically adjust its connection state between LTE and NR networks based on real-time conditions. When the terminal detects that dual connectivity is not necessary (through measurement reports and network condition assessment), it dynamically transitions to single network mode, thereby extending battery life while maintaining sufficient data transmission capability through the active network connection.
Solution Approach 2:
The patent changes the connection configuration parameter from dual connectivity to single network mode when conditions permit. This parameter change reduces the energy required for maintaining multiple network connections, thereby extending battery life, while the terminal continues to provide data transmission services through the remaining network connection.
3Reliability
If the terminal device reports measurement results for the second network, then the network can optimize connection configuration, but the power consumption increases
Solution Approach 1:
The patent applies the extraction principle by selectively reporting only the necessary measurement information to the network. Instead of reporting all measurement results for both LTE and NR networks, the terminal extracts and reports only the essential measurement data needed for connection optimization decisions, thereby reducing the energy consumption associated with comprehensive measurement and reporting while maintaining connection configuration reliability.
Solution Approach 2:
The patent implements partial action by performing measurements and reporting only when necessary for connection optimization. The terminal conducts measurement reports selectively based on network conditions and connection state, rather than continuously reporting all network measurements, thereby reducing power consumption while maintaining sufficient connection configuration optimization.
