Frequency-Diverse ACK Transmission for Crowded Wireless Links
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication methods suffer from errors and collisions due to the immediate return of ACK frames on a single frequency channel, leading to degraded communication quality and inefficient retransmissions, especially in crowded wireless environments.
Innovation Solution
A communicating device transmits and receives data using multiple usable frequency channels, generating request and acknowledgment signals that include channel information to confirm normal reception, allowing for reliable communication by utilizing all available channels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If an ACK frame is returned immediately on a single frequency channel, then the communication protocol is simple, but communication reliability deteriorates due to errors and collisions
Solution Approach 1:
The patent segments the ACK frame transmission by dividing it into multiple parts transmitted on different frequency channels. Instead of sending a single ACK frame on one channel, the system transmits ACK frames on multiple frequency channels simultaneously, which reduces the probability of collision and improves reliability without significantly increasing protocol complexity
Solution Approach 2:
The patent introduces a new dimension to ACK frame transmission by utilizing multiple frequency channels instead of a single channel. This dimensional expansion from one channel to multiple channels allows for more reliable delivery of acknowledgment signals while maintaining manageable protocol complexity through structured multiplexing
2Reliability
If data is transmitted on multiple frequency channels, then communication reliability improves, but device complexity increases
Solution Approach 1:
The patent applies multi-functionality by enabling the communication device to handle both data transmission and ACK frame transmission across multiple frequency channels using the same fundamental transmission mechanisms. The device uses universal transmission components to manage multiple channels, reducing the need for separate dedicated hardware for each function
Solution Approach 2:
The patent merges the data transmission and ACK frame transmission functions into a unified multi-channel communication system. By combining these functions and using the same transmission infrastructure for both purposes, the system achieves improved reliability through multiple channels without proportionally increasing device complexity
3Device complexity
If ACK frames are returned on the same frequency channel as data transmission, then the protocol is simple, but communication quality degrades due to collisions
Solution Approach 1:
The patent segments the ACK frame transmission across multiple frequency channels separate from the data transmission channel. This segmentation allows ACK frames to be delivered through different paths, avoiding collisions with data transmissions and improving communication quality while maintaining protocol simplicity through structured separation
Solution Approach 2:
The patent introduces frequency channel diversity as an intermediary mechanism between data transmission and ACK frame delivery. By using multiple frequency channels as intermediate pathways for ACK frames, the system avoids direct collisions on the data channel while maintaining a relatively simple overall protocol structure
