Dynamic Bandwidth Adaptation for Wireless Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication devices face challenges in reducing power consumption while maintaining network throughput and efficiency, particularly due to the increasing demand for advanced features and functionalities in cellular communication systems.
Innovation Solution
Wireless devices dynamically adapt their receiver bandwidth based on network scheduling information, selecting a narrower bandwidth when there is low likelihood of downlink traffic and full bandwidth when there is a high likelihood, thereby reducing power consumption without compromising network efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If wireless devices use full bandwidth continuously, then network throughput and communication capability are maintained, but power consumption increases
Solution Approach 1:
The patent implements dynamic bandwidth adaptation where the wireless device adjusts its receiver bandwidth based on real-time network conditions and traffic likelihood predictions. The device transitions between narrow bandwidth mode (when downlink traffic is unlikely) and full bandwidth mode (when downlink traffic is likely), making the bandwidth setting dynamic rather than fixed. This resolves the contradiction by allowing the system to optimize between power consumption and throughput capability based on actual operational needs.
Solution Approach 2:
The patent changes the bandwidth parameter dynamically based on predicted traffic patterns and network scheduling information. By monitoring factors such as scheduling requests, buffer status reports, and historical traffic data, the system adjusts the receiver bandwidth parameter to match actual communication requirements. This parameter change approach enables the device to reduce bandwidth (and power consumption) when full bandwidth is not needed while maintaining the ability to switch to full bandwidth when throughput becomes critical.
2Use of energy by moving object
If wireless devices reduce receiver bandwidth, then power consumption decreases, but the ability to receive downlink traffic may be compromised
Solution Approach 1:
The patent employs feedback mechanisms where the wireless device continuously monitors network scheduling information, traffic patterns, and communication status to adjust its bandwidth setting. The device receives feedback from the network about scheduled transmissions and uses this information to predict future traffic needs. Based on this feedback loop, the device makes informed decisions about when to operate at reduced bandwidth versus full bandwidth, ensuring reliable downlink traffic reception when needed while optimizing power consumption during low-activity periods.
Solution Approach 2:
The patent applies preliminary action by using network scheduling information and historical data to predict future downlink traffic likelihood before actual traffic occurs. The device proactively adjusts its bandwidth setting based on these predictions rather than reacting after traffic has already occurred. This predictive approach allows the device to prepare for potential communication needs while avoiding unnecessary power consumption during periods when full bandwidth is unlikely to be required.
