Disjoint Field Sets for Multi-Type Channel Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Communicating between devices using different communication types and bandwidths is challenging due to disparate channel bandwidths and center frequencies, making it difficult for legacy and newer devices to interoperate effectively.
Innovation Solution
The method involves receiving and identifying sets of fields indicating channel bandwidth and center frequency index at a station, allowing communication with both legacy and enhanced devices by using disjoint sets of fields, where legacy devices see only one bandwidth and center frequency, while enhanced devices recognize both legacy and enhanced channels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single set of fields is used to indicate channel bandwidth and center frequency, then the communication protocol is simple, but devices of different communication types cannot be distinguished and communicate effectively
Solution Approach 1:
The patent divides the communication protocol into separate field sets for different communication types. First communication type uses a first set of fields while second communication type uses a second set of fields, allowing each type to be optimized independently while maintaining overall system compatibility
Solution Approach 2:
The patent introduces a communication type identifier as an intermediary element that distinguishes between different communication types. This identifier enables the system to select appropriate field sets and interpretation rules, facilitating interoperability between legacy and enhanced devices without requiring a complete protocol redesign
2Adaptability or versatility
If legacy devices use existing bandwidth and frequency parameters, then backward compatibility is maintained, but enhanced devices cannot utilize newer communication capabilities
Solution Approach 1:
The patent implements dynamic field interpretation where the meaning and structure of communication fields change based on the identified communication type. Enhanced devices can dynamically switch between interpreting legacy field formats and enhanced field formats, allowing seamless adaptation to different communication capabilities while maintaining reliable interoperability
Solution Approach 2:
The patent changes the parameters and structure of communication fields based on communication type. The first set of fields uses parameters appropriate for legacy devices while the second set uses enhanced parameters, allowing each device type to operate with optimal parameters while maintaining system-wide compatibility through the type identification mechanism

AI summary
Communications may be effected in a communications environment involving a plurality channels having disparate bandwidth and channel center frequency indexes. Communications are effected using first communications type with a first channel bandwidth and first channel center frequency index. Communications are also effected via a second communications type using a separate set of fields indicating a second channel bandwidth and a second channel center frequency index, the second channel bandwidth being different than the first channel bandwidth and the second channel center frequency index being different than the first channel center frequency index. The channel center frequency index and bandwidth communicated in each communication may utilize separate subfields.
