Multi-Link Communication Awake State Switching Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current multi-band aggregation and collaboration technologies in Wi-Fi lack an effective awake mechanism for stations in power save mode to engage in multi-link communication, which is essential for low-latency and efficient spectrum utilization.
Innovation Solution
A communication method under multiple links is introduced, where a first message frame is determined and sent to switch at least one link to an awake state for multi-link communication. This message frame includes information such as power management identifiers, link identifiers, and delay identifiers to manage the transition effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If stations remain in power save mode to reduce energy consumption, then energy efficiency is improved, but multi-link communication capability deteriorates
Solution Approach 1:
The system performs preliminary actions by sending a first message frame in advance to notify the station to switch from power save mode to awake state before multi-link communication is needed. This allows the station to prepare its communication interfaces ahead of time, ensuring ready-to-go multi-link capability when required while maintaining power save mode during non-communication periods.
Solution Approach 2:
The station dynamically transitions between power save mode and awake state based on communication requirements. The system enables flexible switching of the first station from a low-power state to an active communication state through the message frame mechanism, allowing adaptive adjustment of power consumption levels according to real-time multi-link communication needs.
2Adaptability or versatility
If stations switch to awake state for multi-link communication, then communication capability is improved, but energy consumption increases
Solution Approach 1:
The system implements periodic action by having stations alternate between power save mode and awake state. Stations remain in power save mode during periods when multi-link communication is not required, then switch to awake state periodically when communication is needed. This rhythmic switching pattern minimizes overall energy consumption while ensuring communication capability is available when required.
Solution Approach 2:
The notification mechanism performs preliminary action by alerting the station in advance before multi-link communication begins. This allows the station to switch to awake state only when necessary, avoiding prolonged periods of high energy consumption. The preliminary notification enables precise timing of the state transition, ensuring the station wakes up just in time for communication tasks.
3Manufacturing precision
If message frames include detailed link switching information, then communication control precision is improved, but signaling overhead increases
Solution Approach 1:
The message frame structure is segmented into distinct functional fields: a first field indicating the need for station switching, a second field identifying the target station, and a third field specifying the link identifier. This segmentation allows precise communication control through targeted information in each field while avoiding redundant data, thereby reducing overall signaling overhead compared to a monolithic message structure.
Solution Approach 2:
The invention extracts only the essential information needed for link switching from the full set of possible communication parameters. By taking out only the critical elements (switching indication, station identity, and link identifier) and omitting unnecessary details, the message frame achieves sufficient communication control precision with minimal signaling overhead.
