Wireless Communication Device Multi-Link Redundant Frame Discard
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multi-link transmission technology, data that has already been successfully transmitted over one wireless link may be redundantly transmitted over another link, leading to inefficient communication due to lack of confirmation mechanisms.
Innovation Solution
A wireless communication device is configured to generate frames based on data and management information, confirm successful transmission, and discard frames if notification is received, ensuring that data is only transmitted if confirmation is not received from a different communication device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multi-link transmission technology is used to transmit data in parallel using multiple wireless links, then communication reliability is improved, but communication efficiency deteriorates due to redundant transmissions of already successfully transmitted data
Solution Approach 1:
The patent implements a feedback mechanism where the first wireless base station receives notification information from the second wireless base station about successful data transmissions. Based on this feedback, the first wireless base station determines whether to retransmit the same data, thereby avoiding redundant transmissions while maintaining reliability through multi-link transmission.
2Reliability
If data is transmitted using multiple wireless links without confirmation mechanism, then communication reliability is improved, but communication efficiency deteriorates due to redundant transmissions
Solution Approach 1:
The notification information transmitted from the second wireless base station to the first wireless base station serves as feedback about transmission status. This feedback loop enables the first wireless base station to avoid retransmitting data that has already been successfully transmitted over the second link, thereby reducing unnecessary energy consumption while preserving reliability benefits.
Solution Approach 2:
The first wireless base station discards (does not retransmit) data packets that are marked as already successfully transmitted through notification information from the second link. This selective discarding of redundant transmissions optimizes energy usage while maintaining the reliability advantages of multi-link transmission.

AI summary
According to one embodiment, a wireless communication device includes a control unit and a wireless unit. The control unit is configured to confirm whether or not a notification that a first frame was successfully transmitted is received from a second communication device. The control unit is configured to transmit, in a case where the notification is not received, the first frame to a first communication device via the wireless unit, and transmit, in a case where a response frame with respect to the first frame is successfully received from the first communication device, the notification to the second communication device. The control unit is configured to discard, in a case where the notification is received, the first frame.
