Wi-Fi Data Frame Transmission Using TID-Based Priority Across Links
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Wi-Fi technologies lack a method to define different access medium priorities for data frames during aggregative and collaborative data communication across various frequency bands, leading to QoS instability and inefficient data transmission.
Innovation Solution
The method involves generating and transmitting data frames with a same traffic identifier (TID) across multiple transmission links, ensuring the same access media priority, and dynamically switching links based on traffic conditions to maintain optimal communication quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If data frames are transmitted across multiple frequency bands simultaneously, then transmission rate is improved, but QoS stability deteriorates due to lack of access medium priority definition
Solution Approach 1:
The patent segments data frames by assigning different Traffic Identifiers (TIDs) to different types of data content, enabling separate priority handling for each segment across multiple frequency bands
Solution Approach 2:
The patent applies different access medium priorities to different TIDs locally, allowing each data type to receive appropriate priority treatment on each frequency band while maintaining overall QoS stability
2Productivity
If multiple transmission links are used for data transmission, then data transmission efficiency is improved, but complexity of priority management increases
Solution Approach 1:
The patent creates a universal priority management mechanism where TID-to-priority mapping is consistently applied across all transmission links, allowing the same priority rules to function universally on every frequency band without requiring link-specific configurations
Solution Approach 2:
The patent changes the parameter structure by introducing TID as a key identifier that directly maps to access medium priority, simplifying the management complexity through parameter standardization across multiple links

AI summary
A method for transmitting data includes generating a plurality of first data frames based on the same type of data content, wherein the plurality of first data frames have the same traffic identifier (TID), and the plurality of first data frames having the same TID have the same access media priority in a plurality of transmission links; and transmitting the plurality of first data frames having the same TID using the plurality of transmission links. An apparatus for performing the method may include a terminal in a wireless communication network.
