Non-AP MLD Link State Management for Multi-Link Power Saving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multi-link wireless communication scenarios, non-access point multi-link devices (Non-AP MLDs) waste power due to maintaining multiple activated links during frame interactions, leading to unnecessary power consumption.
Innovation Solution
A method and apparatus for Non-AP MLDs to determine a target link based on a target radio frame and configure stations corresponding to that link in a power-saving state, reducing power consumption by keeping other links in a power-saving state during frame interactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If Non-AP MLD maintains multiple activated links during frame interactions, then communication reliability is improved, but power consumption increases
Solution Approach 1:
The patent implements dynamic link state management where links can transition between activated and power-saving states based on communication needs. The Non-AP MLD selectively activates only the link required for current frame interactions while placing other links in power-saving state, making the system adaptable to varying communication demands rather than maintaining all links in a fixed activated state
Solution Approach 2:
The patent segments the multi-link system into independent controllable units where each link can be independently managed. By identifying a target link for frame interactions and separating it from other non-target links, the system can apply different power states to different segments (links) based on their specific communication requirements, reducing overall power consumption while maintaining necessary communication functionality
2Speed
If Non-AP MLD keeps all links activated for frame interactions, then communication speed is improved, but power consumption increases
Solution Approach 1:
The system dynamically adjusts link activation status based on real-time communication requirements. During frame interactions, only the target link remains activated to ensure communication speed, while other links transition to power-saving state. This dynamic adjustment allows the system to maintain high communication speed when needed while minimizing power consumption during idle periods on non-target links
Solution Approach 2:
The patent applies different operational qualities to different links based on their specific roles. The target link maintains full activation and communication capability (high quality) during frame interactions, while non-target links are placed in power-saving state (reduced quality). This localized quality differentiation ensures that communication speed is maintained on the active link while reducing overall power consumption
