Dynamic TWT Interval Adjustment for Wi-Fi Power Savings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for determining Target Wake Time (TWT) parameters in wireless local area networks (WLANs) do not adaptively account for traffic characteristics, leading to inefficiencies in power savings and potential increases in latency.
Innovation Solution
The proposed solution involves an electronic device with a transceiver and processor that adjusts the TWT interval based on the device's idle or active state, determined by traffic statistics or application identifiers, to enhance power savings while maintaining acceptable latency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the TWT interval is extended to increase power savings, then energy consumption is reduced, but latency increases and user experience deteriorates
Solution Approach 1:
The TWT interval is made dynamic rather than fixed. The system continuously monitors traffic characteristics and adjusts the TWT interval in real-time based on current network conditions and application requirements, allowing optimization of both power savings and latency according to actual usage patterns
Solution Approach 2:
The patent changes the parameter values of TWT interval based on traffic characteristics. By analyzing application identifiers and traffic statistics, the system selects appropriate TWT interval values from a range, extending the interval for power-intensive applications with tolerant latency and reducing it for latency-sensitive applications
2Device complexity
If fixed TWT parameters are used to simplify configuration, then device complexity is reduced, but adaptability to different traffic characteristics is lost
Solution Approach 1:
The system performs self-configuration by automatically analyzing traffic characteristics and selecting appropriate TWT parameters without requiring manual intervention. The device monitors its own traffic patterns and autonomously adjusts TWT intervals, eliminating the need for complex manual configuration while maintaining high adaptability
Solution Approach 2:
The system implements feedback mechanisms by continuously monitoring traffic statistics and application identifiers, then using this information to dynamically adjust TWT parameters. This closed-loop approach enables automatic adaptation to different traffic characteristics without increasing configuration complexity for the user

AI summary
Embodiments of the present disclosure provide methods and apparatuses for adjusting target wake time (TWT) parameters, and in particular a TWT interval. An apparatus comprises a transceiver and a processor operably coupled to the transceiver. The transceiver is configured to receive WI-FI traffic for an application in a target wake time (TWT) operation. The processor is configured to identify whether a state of the electronic device is idle or active based on at least one of a traffic statistic related to the WI-FI traffic or an application identifier of the application and adjust a TWT interval of the TWT operation based on the state.
