Wireless Frame Transmission Spatial Reuse Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems with increasing Internet of Things devices, the network load becomes heavier, leading to decreased communication efficiency, and some frame sequences require protection from reuse by other stations to ensure successful transmission.
Innovation Solution
A method and apparatus that determine if a radio frame is of a specified type or carries indication information disallowing reuse by third parties, maintaining a physical carrier channel detection state as busy until the frame ends, ensuring transmission success and improving network efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If spatial reuse technology is enabled to allow stations in different BSSs to reuse the same channel at the same time, then network throughput is improved, but transmission reliability of protected frame sequences deteriorates
Solution Approach 1:
The patent applies local quality by differentiating treatment of different frame types. Protected frame sequences (beacon frames, CTS-to-self frames, etc.) are identified and granted special protection status, while other frames continue to allow spatial reuse. This selective approach ensures that critical frames maintain high reliability while non-critical frames can benefit from spatial reuse to improve overall throughput.
Solution Approach 2:
The patent implements preliminary anti-action by pre-identifying protected frame sequences before transmission and pre-configuring protection mechanisms. When a protected frame is detected, the system proactively prevents spatial reuse by other stations during the transmission duration, thereby preventing potential interference before it occurs. This is achieved through frame type identification and setting protection flags in advance.

If spatial reuse is allowed for all frames, then channel utilization is improved, but transmission success rate of specified frame types deteriorates

3Productivity
If third-party stations are allowed to reuse channels during ongoing transmissions, then network efficiency is improved, but interference to subsequent transmissions increases
Solution Approach 1:
The patent implements preliminary anti-action by pre-identifying protected frame sequences before transmission and pre-configuring protection mechanisms. When a protected frame is detected, the system proactively prevents spatial reuse by other stations during the transmission duration, thereby preventing potential interference before it occurs. This is achieved through frame type identification and setting protection flags in advance.
Solution Approach 2:
The patent applies feedback by monitoring received frames and their types, then dynamically adjusting spatial reuse permissions based on the frame content. When a protected frame type is detected, the system provides feedback to prevent further reuse attempts during the transmission duration, ensuring that interference is avoided while maintaining efficient reuse for non-protected frames.
