Solution Overview
Problem
Current technologies for 3GPP LTE and New Radio (NR) systems do not effectively manage Connected Discontinuous Reception (CDRX) while considering real-time power consumption of devices.
Innovation Solution
Determine the CDRX value based on analytics information that takes into account the power consumption of the device, allowing for dynamic adjustments to improve efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If CDRX value is increased to reduce power consumption, then device battery life is improved, but service responsiveness and data transmission efficiency deteriorate
Solution Approach 1:
The patent implements dynamic CDRX configuration where the base station adjusts CDRX parameters (onDurationTimer, drx-InactivityTimer, drx-LongCycleStartOffset, etc.) in real-time based on UE power consumption analytics, service type, and traffic patterns. This dynamic adjustment allows the system to optimize between power savings and service responsiveness by adapting CDRX values to current operational conditions rather than using fixed configurations.
Solution Approach 2:
The patent changes physical parameters of the CDRX configuration (timer values, cycle lengths) based on analytics information about power consumption and service requirements. By modifying these parameters dynamically, the system can shift the balance between power consumption and service responsiveness according to actual needs, resolving the contradiction between battery life and responsiveness.
2Productivity
If CDRX value is decreased to improve service responsiveness, then data transmission efficiency is improved, but device power consumption increases
Solution Approach 1:
The patent employs feedback mechanisms where the base station receives analytics information about UE power consumption status and service performance, then uses this feedback to adjust CDRX configuration. The network node continuously monitors power consumption analytics and modifies CDRX parameters accordingly, creating a closed-loop system that resolves the contradiction by adapting to real-time conditions.
Solution Approach 2:
The system transitions from static CDRX configuration to dynamic adjustment based on real-time analytics. The base station can increase or decrease CDRX aggressiveness (shorter or longer timers/cycles) depending on current power consumption levels and service requirements, allowing flexible resolution of the productivity-power consumption trade-off.
3Device complexity
If fixed CDRX configuration is used to simplify system structure, then device complexity is reduced, but adaptability to different service scenarios deteriorates
Solution Approach 1:
The patent enables the system to self-adjust CDRX configuration automatically based on analytics information without requiring complex manual configuration or user intervention. The base station autonomously determines appropriate CDRX parameters by analyzing power consumption data and service requirements, maintaining simplicity while achieving high adaptability through automated decision-making.
Solution Approach 2:
The patent transforms the static CDRX configuration into a dynamic system that automatically adapts to different service scenarios (eMBB, mMTC, URLLC) and power consumption states. This dynamic capability provides versatility across multiple service types while keeping the implementation relatively simple through standardized analytics-based adjustment mechanisms.
