Multi-band Authentication Frame for Wireless Latency Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing complexity of multi-band devices in wireless communications, such as those supporting IEEE 802.11 standards across multiple frequency bands, poses a challenge in improving authentication and association efficiency, leading to higher latency and resource overheads.
Innovation Solution
A multi-band communication method that utilizes a single frame to request authentication, association, or reassociation across multiple bands, allowing devices to perform these operations through one-time information exchange, reducing latency and improving efficiency by using request bits corresponding to each band within multi-band elements or neighbor report elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional separate authentication and association procedures are used for each band, then authentication and association can be performed reliably, but authentication and association latency increases and efficiency decreases
Solution Approach 1:
The patent combines multiple authentication and association requests for different bands into a single frame (first frame), allowing the first device to process all requests simultaneously through one information exchange, thereby reducing latency while maintaining reliability
Solution Approach 2:
The first frame is designed with multi-functionality to carry authentication, association, and reassociation requests for multiple bands simultaneously, enabling a single frame to perform what traditionally required multiple separate frames
2Adaptability or versatility
If multiple separate frames are used for authentication and association in different bands, then each band can be handled independently, but information exchange overhead and system resource overhead increase
Solution Approach 1:
Multiple band-specific requests are merged into a single first frame, reducing the quantity of information exchanged while preserving the ability to handle each band independently through request bits
Solution Approach 2:
The first frame contains segmented request bits for different bands, allowing independent handling of each band's authentication and association while transmitting everything in one consolidated frame

AI summary
This application provides an example multi-band communication method and an example apparatus. One example method includes a first device receives a first frame sent by a second device, where the first frame carries request information used to request to perform authentication, association in at least two bands, or reassociation in the at least two bands. The example method also includes based on the request information carried in the first frame, the first device authenticates, the first device is associated with the second device in the at least two bands, or the first device is reassociated with the second device in the at least two bands.
