Electronic Device MAC Frame Parity Encoding for Vendor Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication chips from different vendors in electronic devices often perform poorly in complex environments due to varying functions and interference, leading to suboptimal communication quality.
Innovation Solution
An electronic device generates a parity by performing a specific encoding operation on a MAC frame's duration/ID field, replacing part of its content to create a modified field, and sends this frame to another device to determine vendor compatibility, allowing improved communication quality through vendor-specific adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wireless communication chips from different vendors are used in electronic devices, then device compatibility and vendor flexibility are improved, but communication quality deteriorates in complex environments due to varying chip functions and interference
Solution Approach 1:
The patent applies preliminary action by performing encoding operations on the duration/ID field before transmission. The transmitting device encodes this field with vendor-specific information in advance, allowing the receiving device to proactively identify the vendor type and prepare appropriate communication parameters before actual data exchange, thus improving communication quality in complex environments
Solution Approach 2:
The patent implements parameter changes by modifying the duration/ID field to include vendor identification information. This parameter modification enables the receiving device to distinguish between different vendor chips and adjust communication parameters accordingly, resolving the contradiction between vendor flexibility and communication reliability
2Reliability
If vendor identification methods are implemented to improve communication quality, then communication quality is improved through vendor-specific adjustments, but device complexity increases due to additional identification and encoding operations
Solution Approach 1:
The patent applies the taking out principle by extracting vendor identification information from separate vendor-specific frames and integrating it into the existing duration/ID field. This extraction and integration approach allows vendor identification without requiring additional communication frames or complex separate identification protocols, thus improving communication quality while minimizing device complexity
Solution Approach 2:
The patent implements universality by making the duration/ID field serve multiple functions: it maintains its original role in indicating transmission duration while simultaneously encoding vendor identification information. This multi-functionality eliminates the need for separate vendor identification mechanisms, improving communication quality without significantly increasing device complexity
