SL-DRX Configuration for Relay Node Energy Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communications, especially in LTE-based Machine Type Communication (MTC) scenarios, relay devices face high energy consumption due to continuous data detection, which is inefficient for wearable devices with low data demands, leading to increased energy usage and costs.
Innovation Solution
Implementing discontinuous reception (DRX) on sidelinks, referred to as SL-DRX, to configure intermittent detection of control channels, reducing power consumption by determining active and sleep times for relay and remote network nodes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If relay devices continuously detect data to ensure reliable communication, then communication reliability is improved, but energy consumption increases
Solution Approach 1:
The patent implements discontinuous reception (DRX) on sidelinks, where relay and remote network nodes alternately enter active and sleep states. During active periods, nodes detect control channels and transmit/receive data; during sleep periods, nodes reduce power consumption by stopping detection. This periodic operation pattern resolves the contradiction by maintaining communication reliability during active periods while reducing energy consumption during sleep periods.
2Stability of the object's composition
If relay devices operate continuously to maintain connection, then connection stability is improved, but operational costs increase
Solution Approach 1:
The patent configures SL-DRX with specific active and sleep time periods for relay and remote network nodes. During active periods, nodes maintain stable connections through continuous monitoring and data transmission. During sleep periods, nodes reduce operational costs by minimizing power consumption while maintaining the ability to quickly resume communication. This periodic operation resolves the contradiction between connection stability and operational costs.
