Grouped Acknowledgment Frame for Wi-Fi Spectrum Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Wi-Fi technologies face inefficiencies in spectrum utilization and power saving due to the sequential acknowledgment of uplink data, which limits effective communication and increases power consumption in user equipment.
Innovation Solution
A data transmission method that generates a chunking acknowledgment message frame to simultaneously indicate the receiving states of multiple transmitters within a group, allowing for grouped acknowledgment and reduced ACK frames, thereby improving spectrum utilization and power efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sequential acknowledgment frames are sent to multiple users, then each user receives individual acknowledgment, but spectrum utilization deteriorates and power consumption increases
Solution Approach 1:
The patent combines multiple individual acknowledgment frames into a single group acknowledgment frame that serves multiple users simultaneously. The group acknowledgment frame contains acknowledgment information for multiple users, allowing the access point to acknowledge multiple uplink transmissions in one downlink frame, thereby improving spectrum utilization while maintaining reliable acknowledgment delivery.
Solution Approach 2:
The patent segments the acknowledgment information into user-specific portions within a single group acknowledgment frame. Each user can identify their own acknowledgment status through user identification fields in the frame, allowing individual acknowledgment delivery while transmitting all acknowledgments in a unified structure that improves overall spectrum efficiency.
2Reliability
If sequential acknowledgment frames are sent to multiple users, then each user receives individual acknowledgment, but power consumption deteriorates
Solution Approach 1:
The patent merges multiple acknowledgment operations into a single group acknowledgment frame transmission. Users wake up once to receive the group acknowledgment frame instead of waking up separately for each individual acknowledgment, significantly reducing their power consumption while ensuring they still receive reliable acknowledgment delivery for their uplink transmissions.
3Reliability
If individual acknowledgment frames are used for each transmitter, then transmission reliability is maintained, but communication efficiency deteriorates
Solution Approach 1:
The patent combines multiple individual acknowledgment frames into a single group acknowledgment frame that maintains transmission reliability through user-specific acknowledgment fields while improving communication efficiency by reducing the total number of frames transmitted and the time required for acknowledgment exchange.
