Radio Node Power Saving via Data Transmission Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radio communication systems waste power due to continuous radio wave output even when no data is being transmitted, as the terminal communication unit periodically sends beacon signals, leading to inefficiencies in power saving.
Innovation Solution
A radio node with a determination unit that checks if any communication apparatus is transmitting data and a control unit that stops the communication unit when no data is being transmitted, reducing unnecessary power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal communication unit continuously outputs radio waves to send beacon signals, then the radio terminal can be searched and connected, but power is wasted when no data transmission is needed
Solution Approach 1:
The terminal communication unit transitions from continuous periodic beacon signal transmission to on-demand operation. The unit is stopped when no data transmission is detected and restarted when data transmission is needed, converting continuous periodic action into conditional intermittent action to reduce power consumption while maintaining connection capability.
Solution Approach 2:
The terminal communication unit autonomously determines when to operate based on detecting data transmission activity. The determination unit monitors data transmission status and automatically controls the communication unit's operation state without external intervention, enabling the system to self-adjust power consumption based on actual communication needs.
2Loss of energy
If the radio base station stops inter-station communication to save power, then power consumption is reduced, but terminal communication power is not saved
Solution Approach 1:
The communication system is segmented into inter-station communication function and terminal communication function. The patent applies different power saving strategies to each segment: inter-station communication is stopped when not needed, while terminal communication unit is controlled based on data transmission detection. This segmentation allows targeted power saving without compromising overall communication reliability.
Solution Approach 2:
Different quality levels are applied to different communication functions based on actual needs. The terminal communication unit maintains high readiness (continuous monitoring capability) when data transmission is detected, while operating in low-power mode when idle. This local quality adjustment optimizes power consumption while ensuring communication reliability where needed.
3Loss of energy
If the communication unit is stopped to save power, then power consumption is reduced, but the ability to detect and connect to radio terminals is affected
Solution Approach 1:
A feedback mechanism is implemented where the determination unit continuously monitors data transmission status and provides feedback to the control unit. Based on this feedback, the communication unit's operation state is dynamically adjusted. This feedback loop ensures the system responds appropriately to communication needs while optimizing power consumption.
Solution Approach 2:
The determination unit performs preliminary detection of data transmission status before controlling the communication unit's operation. By detecting data transmission needs in advance, the system can proactively activate or deactivate the communication unit, ensuring readiness when needed while avoiding unnecessary power consumption during idle periods.
