Short Control Frames in Wireless PHY Preambles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication systems face significant network and processing overhead due to the size of control frames, which include control information and payload data, leading to increased latency and processing burdens.
Innovation Solution
The system generates and transmits short control frames by omitting unnecessary information and encoding control frames within the Signal (SIG) field of the Physical Layer (PHY) preamble, reducing the size of control frames and minimizing additional fields, thereby reducing network overhead and processing latency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If control frames include control information and payload data, then communication functionality is improved, but network overhead and processing latency increase
Solution Approach 1:
The patent extracts and removes the payload data portion from control frames, retaining only the essential control information. This extraction principle directly reduces frame size and eliminates unnecessary processing of payload content, thereby reducing processing latency while maintaining core communication functionality.
Solution Approach 2:
The patent employs short control frames as simplified, disposable communication units that carry only essential control information without persistent payload data. These short-lived control frames reduce network overhead and processing requirements, allowing receivers to quickly process and discard them after extracting control information.

3Reliability
If control frames are transmitted with full structure, then reliability is improved, but device complexity increases
Solution Approach 1:
The patent employs short control frames as simplified, disposable communication units that carry only essential control information without persistent payload data. These short-lived control frames reduce network overhead and processing requirements, allowing receivers to quickly process and discard them after extracting control information.
Solution Approach 2:
The patent changes the parameter of frame structure by transmitting control information in a condensed format within the PHY preamble rather than using traditional MAC layer framing. This parameter change reduces the complexity of frame processing while maintaining communication reliability through the use of established PHY layer protocols.
