Seamless Wireless Fragment Retransmission via Request ID
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic devices in wireless network systems experience increased power consumption and insufficient channel capacity due to repeated frame exchanges and lost frames during Generic Advertisement Service (GAS) transactions, leading to inefficient data transmission.
Innovation Solution
A method and apparatus for seamless transmission control that involves sending a request frame with a fragment ID to trigger retransmission of incomplete data portions, reducing the number of frame exchanges by utilizing response frames to carry remaining data fragments, thereby avoiding repeated transmissions and optimizing channel usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional electronic devices wait for timeout during GAS fragmentation, then the transaction can be completed, but power consumption increases and the whole transaction may need to restart
Solution Approach 1:
The patent applies preliminary action by having the electronic device send a request frame carrying fragment ID before the timeout occurs, proactively triggering the responder to retransmit only the lost fragment. This prevents the need to wait for timeout and avoids restarting the whole transaction, thereby reducing power consumption while maintaining reliable transaction completion.
2Reliability
If conventional electronic devices restart the whole transaction after timeout, then data can be retransmitted, but the number of frame exchanges increases and channel capacity becomes insufficient
Solution Approach 1:
The patent extracts only the necessary part (the lost fragment) for retransmission by using fragment ID to identify and request only the specific fragment that was lost, rather than restarting the entire transaction. This reduces the number of frame exchanges and improves channel capacity utilization while maintaining reliable data transmission.
Solution Approach 2:
The patent segments the data transmission into multiple fragments with unique IDs, allowing selective retransmission of only the lost fragment. This segmentation approach reduces the overall number of frame exchanges compared to restarting the whole transaction, thereby improving channel capacity utilization.
3Adaptability or versatility
If the number of frame exchanges is proportional to the number of devices sending GAS-related frames, then all devices can communicate, but the total channel capacity becomes insufficient when there are many users
Solution Approach 1:
The patent extracts only the necessary retransmission frames for devices that experienced losses, rather than having all devices participate in full retransmission cycles. By using fragment ID to target only affected devices and fragments, the system reduces the total number of frame exchanges while maintaining adaptability for multi-device communication.

AI summary
A method for performing seamless transmission control for an electronic device and an associated apparatus are provided, where the method includes the steps of: sending a request frame carrying a fragment identification (ID) to trigger a responder in a wireless network system to initiate retransmission corresponding to the fragment ID, wherein the fragment ID indicates beginning of a remaining portion within a plurality of fragments of data being sent from the responder to the electronic device; and receiving at least one response frame sent from the responder, for utilizing the remaining portion within the plurality of fragments of the data, wherein the remaining portion within the plurality of fragments of the data is obtained from the at least one response frame.
