Multi-Link Beacon Frame Link Selection for Power Saving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Wi-Fi technologies lack a method to determine which link to use for beacon frame listening or Keep alive frame transmission in a power-saving state during multi-link communication, leading to potential disconnection issues.
Innovation Solution
A communication method and device that determine a first message frame with an information identification bit to identify the appropriate link for communication between a station in a power-saving state and an access point supporting multi-link communication, allowing for efficient listening or transmitting on the designated link.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If a station operates in power-saving state during multi-link communication, then energy consumption is reduced, but the station may miss beacon frames or Keep alive frames causing disconnection
Solution Approach 1:
The patent segments the multiple communication links and identifies a specific first link for power-saving station use. By dividing the multi-link system into distinct functional links, the station can operate in power-saving mode on non-first links while maintaining connection reliability through the designated first link for beacon frame listening and Keep alive frame transmission.
2Reliability
If the station listens to all links for beacon frames, then connection reliability is maintained, but signaling interaction increases and energy consumption rises
Solution Approach 1:
The patent extracts the critical function of beacon frame listening and Keep alive frame transmission from all multiple links and isolates it to a specific first link. This allows the power-saving station to only monitor the essential first link rather than all links, reducing signaling interaction and energy consumption while maintaining connection reliability.
3Device complexity
If no link identification mechanism is used, then device complexity is low, but the station cannot determine which link to use for communication in power-saving state
Solution Approach 1:
The patent introduces a link identification mechanism that assigns specific characteristics to different links. The first link is marked with specific identification information that enables power-saving stations to easily recognize and select the appropriate link for communication, simplifying the station's operation without requiring complex decision algorithms.
