Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-link devices experience high power consumption due to simultaneous activation of multiple links, which is particularly problematic for battery-powered devices, and there is a need for efficient power management in multi-link associations.
Innovation Solution
A method and device for establishing a multi-link association that includes determining the required device and setting appropriate association modes, such as active or sleep modes, to optimize power usage, using higher and lower layer management entities to manage link associations effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple links are simultaneously activated for data transmission in multi-link devices, then data transmission capability and throughput are improved, but power consumption increases significantly
Solution Approach 1:
The patent implements dynamic link management where links can be activated or deactivated based on real-time data transmission requirements. The access point and station maintain multiple potential links but only activate the necessary number for current traffic needs, allowing the system to adapt between high throughput modes (multiple active links) and low power modes (fewer active links) dynamically
Solution Approach 2:
The patent applies partial action by activating only the minimum necessary number of links required for current data transmission needs rather than maintaining all possible links in active state. This allows the system to achieve sufficient throughput with fewer active links, thereby reducing power consumption while maintaining adequate productivity
2Reliability
If all links are kept in active mode to ensure data transmission, then transmission reliability is improved, but battery life deteriorates
Solution Approach 1:
The system dynamically adjusts link activation states based on real-time assessment of transmission reliability requirements. When reliability is critically needed, additional links are activated; when reliability requirements are met with fewer links, other links are deactivated to conserve battery power, creating a dynamic balance between reliability and battery life
3Productivity
If multiple links are activated simultaneously, then throughput is improved, but device complexity increases
Solution Approach 1:
The patent segments link management into distinct functional components: link establishment phase (where multiple links are configured), link activation phase (where necessary links are enabled based on traffic needs), and link monitoring phase (where active links are assessed for continued necessity). This segmentation simplifies the overall management complexity by breaking down the complex multi-link coordination into manageable, sequential stages

AI summary
The embodiments of the disclosure disclose a method for establishing an association of a multi-link device, a electronic device, and a storage medium. The method includes: a higher layer management entity of a first multi-link device determines that a device required to be associated is a second multi-link device, and sends a multi-link association request primitive to a lower layer management entity, the primitive includes an address of the second multi-link device, and information of at least two groups of links requesting to establish an association, the information of the links requesting to establish an association includes identifiers of the links requesting to establish an association, and association modes corresponding to the links, and association modes corresponding to links requesting to establish an association are set as active modes, which the links requesting to establish an association are included in information of at least one group of links requesting to establish an association; and the lower layer management entity establishes an association with the second multi-link device according to the multi-link association request primitive.
