Aggregated Trigger Frame for Multi-Link Communication Overhead
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In Multi-Link communication, transmitting different parameters for each link using conventional Trigger frames results in increased communication overhead, as multiple frames are required, leading to inefficiencies in frequency usage and power consumption.
Innovation Solution
A communication apparatus that transmits a Trigger frame with a Common Info field and a User Info field for each link, allowing for efficient parameter transmission and reducing the need for multiple frame transmissions by incorporating link-specific information within the frame.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If multiple Trigger frames are transmitted for each link to convey different parameters, then link-specific parameter transmission is achieved, but communication overhead increases
Solution Approach 1:
The patent combines multiple Trigger frames into a single aggregated Trigger frame that contains parameter information for multiple links. The aggregation unit consolidates Common Info fields and User Info fields from individual Trigger frames, creating one unified frame that carries all necessary parameters for multi-link operation, thereby reducing the total number of frames transmitted
Solution Approach 2:
The aggregated Trigger frame serves multiple functions simultaneously: it conveys common parameters applicable to all links in the Common Info field, and link-specific parameters in the User Info field. This multi-functional design allows a single frame to replace multiple separate frames, reducing overhead while maintaining complete parameter transmission
2Loss of information
If multiple Trigger frames are transmitted for each link, then distinct parameters for each link are conveyed, but frequency usage efficiency decreases
Solution Approach 1:
The patent merges multiple Trigger frame transmissions into a single aggregated frame transmission. By consolidating parameter information for multiple links into one frame, the system reduces the total transmission time and frequency resources consumed, while still maintaining distinct parameter values for each link through the User Info field structure
3Loss of information
If multiple Trigger frames are transmitted for each link, then complete parameter control is achieved, but power consumption increases
Solution Approach 1:
The aggregation unit combines multiple Trigger frame transmissions into a single aggregated frame. This reduction in the number of transmissions directly lowers the power consumption associated with frame generation, processing, and wireless transmission, while the aggregated frame maintains complete parameter control for all links through its structured Common Info and User Info fields

AI summary
When a communication apparatus establishes connection with a different communication apparatus via a plurality of links, the communication apparatus transmits a Trigger frame being a Trigger frame defined by an Institute of Electrical and Electronics Engineers (IEEE) 802.11 standard, which is transmitted to the different communication apparatus, and in which a set of a Common Info field and a User Info field in the Trigger frame is included for each established link.
