Multi-Link Device Transmission Mode Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional multi-link communication systems face challenges in simultaneously ensuring data transmission reliability and rate, as using multiple links for communication between multi-link devices often results in compromised reliability or rate due to resource occupancy and link interference.
Innovation Solution
A communication method where a second multi-link device determines, based on a message from a first multi-link device, to send data in either duplication or non-duplication transmission modes, optimizing the use of multiple links to improve efficiency while maintaining reliability by adjusting transmission modes based on traffic identifier (TID) or traffic stream (TS) type data and link-specific thresholds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the same data is transmitted over multiple links, then reliability of data transmission is improved, but resource occupancy increases and transmission rate is reduced
Solution Approach 1:
The patent implements dynamic transmission mode selection where the system can switch between duplication transmission mode and non-duplication transmission mode based on real-time conditions. The second multi-link device determines the appropriate mode by evaluating link quality, data type, and transmission requirements, allowing the system to optimize between reliability and transmission rate dynamically rather than using a fixed approach
Solution Approach 2:
The patent applies different transmission modes to different data types and different link combinations. By categorizing data into various types (e.g., control data, user data) and assigning appropriate transmission modes to each type on specific links, the system ensures high reliability for critical data while maintaining high transmission rates for non-critical data, achieving local optimization across the communication system
2Productivity
If different data is transmitted over multiple links, then transmission rate is improved, but reliability of data transmission is reduced
Solution Approach 1:
The system dynamically adjusts transmission modes based on real-time link quality assessment and data type identification. When link conditions deteriorate or data requires high reliability, the system switches to duplication mode; when conditions are good and speed is prioritized, it uses non-duplication mode, enabling adaptive optimization of the reliability-rate tradeoff
Solution Approach 2:
Different transmission modes are applied selectively to different data types and link combinations. Critical control data receives duplication transmission for reliability, while less critical user data can use non-duplication mode for higher rates, achieving differentiated quality of service across different data streams
3Productivity
If multiple links are used for communication between multi-link devices, then data transmission capacity is improved, but effective utilization of links for both reliability and rate cannot be ensured
Solution Approach 1:
The patent implements a dynamic transmission mode determination mechanism where the second multi-link device evaluates multiple factors including link quality, data type, and transmission requirements to select the appropriate mode for each data transmission, enabling the system to fully utilize multiple links while simultaneously ensuring both reliability and rate for different data streams
Solution Approach 2:
The system changes transmission parameters (duplication mode vs. non-duplication mode) based on evaluated conditions such as link quality metrics, data type characteristics, and transmission priority levels. This parameter adjustment allows the system to optimize link utilization dynamically, ensuring that multiple links are effectively used to achieve both high capacity and high reliability

AI summary
Embodiments of this application disclose a second multi-link device that receives a first message from a first multi-link device, and determines, based on the first message, to send data to the first multi-link device in a duplication transmission mode or a non-duplication transmission mode. The first message indicates transmission modes for the second multi-link device to send different types of data, and the transmission modes include the duplication transmission mode and the non-duplication transmission mode.
