Base Station DRX/DTX Control for Lower Power Consumption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The method of reducing power consumption of base stations has not been standardized in conventional technologies, which is crucial for achieving carbon neutrality and Sustainable Development Goals (SDGs).
Innovation Solution
A base station is equipped with a control unit for enabling and disabling transmitting and receiving units, along with a transmission and reception unit that operates only when enabled, utilizing discontinuous transmission and reception functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If base stations operate continuously to maintain communication readiness, then communication reliability is improved, but power consumption increases
Solution Approach 1:
The base station implements discontinuous reception (DRX) and discontinuous transmission (DTX) functions that enable periodic switching between active and sleep states. The receiver is enabled during active periods to maintain communication readiness, then disabled during sleep periods to reduce power consumption. This periodic operation pattern allows the system to balance reliability requirements with energy conservation goals.
2Use of energy by moving object
If base stations reduce power consumption through discontinuous operation, then energy efficiency is improved, but communication responsiveness may deteriorate
Solution Approach 1:
The base station employs dynamic control of transmission and reception units based on traffic conditions and priority levels. The control unit adjusts the timing and duration of active periods, enabling the system to respond dynamically to varying communication demands. High-priority communications can trigger immediate wake-up of the receiver, ensuring responsive service while maintaining energy-saving operation during low-activity periods.
