Trigger Frame Identifier Segmentation for WLAN Power Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless local area networks (WLANs), multiple access points (APs) struggle to configure sending and receiving addresses for data, leading to unnecessary power consumption in non-receiver nodes as they parse trigger frames intended for other nodes.
Innovation Solution
A method and apparatus that enable a first communication node to send a wireless signal with a trigger frame to multiple second communication nodes, using identifier information to specify the sender, receiver, and purpose of the trigger frame, allowing non-receiver nodes to filter out irrelevant data and conserve power.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple APs send trigger frames to multiple STAs, then network communication capability is improved, but power consumption of non-receiver nodes increases due to inability to filter irrelevant data
Solution Approach 1:
The trigger frame is segmented to include distinct identifier fields (first identifier for sender, second identifier for receiver, third identifier for trigger type). This segmentation allows receiving nodes to quickly parse and filter frames based on their role, enabling non-receiver nodes to discard irrelevant frames without full processing, thus reducing power consumption while maintaining multi-AP communication capability
Solution Approach 2:
Different identifier fields are assigned specific local qualities or characteristics within the trigger frame structure. The first identifier specifically marks the sender, the second identifies the intended receiver, and the third indicates the trigger type. This local quality differentiation enables efficient filtering by non-receiver nodes, allowing them to identify and discard frames not intended for them, thereby reducing overall power consumption in the network
2Productivity
If trigger frames are sent to multiple nodes, then transmission coordination is improved, but data processing overhead increases for non-receiver nodes
Solution Approach 1:
The trigger frame is prepared in advance with all necessary identifier information (sender ID, receiver ID, trigger type) embedded in its structure. This preliminary action of pre-configuring the frame with filtering capabilities allows receiving nodes to make quick decisions about frame relevance without requiring complex real-time analysis, thus reducing processing overhead while maintaining coordination efficiency
Solution Approach 2:
The essential filtering information (identifier fields) is extracted and placed in the trigger frame structure. By taking out the critical identification data and making it readily accessible in the frame, non-receiver nodes can efficiently extract and act on this information to discard irrelevant frames, reducing overall data processing overhead while maintaining transmission coordination

AI summary
Provided are a data sending and receiving method and apparatus and a storage medium. The methods include sending a wireless signal that includes a trigger frame to one or more second communication nodes. The trigger frame is configured to trigger one or more second communication nodes to start transmission. The wireless signal carries at least one of first identifier information, second identifier information or third identifier information. The first identifier information is used to identify the sender of the trigger frame. The second identifier information is used to identify the receiver of the trigger frame. The third identifier information is used to identify that the trigger frame is configured to trigger the second communication node to start transmission.
