Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems in the millimeter-wave band face challenges in efficiently communicating Enhanced Directional Multi-Gigabit (EDMG) Orthogonal Frequency-Division Multiplexing (OFDM) Physical Layer Protocol Data Units (PPDUs, particularly due to issues related to spoofing errors that affect data transmission rates and reliability.
Innovation Solution
Incorporating a spoofing error length indicator field in the EDMG PPDU header to indicate whether the spoofing error is less than or greater than one OFDM symbol duration, allowing for accurate padding and transmission adjustments, thereby enhancing data transmission efficiency and reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a spoofing error length indicator field is added to the EDMG PPDU header to improve accuracy in handling spoofing errors, then the header complexity increases
Solution Approach 1:
The header is segmented into multiple fields, with the spoofing error length indicator being a distinct field that provides specific information about spoofing errors. This segmentation allows the indicator to be added without fundamentally restructuring the entire header, thereby managing complexity while improving precision.
Solution Approach 2:
The spoofing error length indicator field acts as an intermediary element between the transmitted signal and the receiver's error detection mechanism. It provides intermediate information about the spoofing error characteristics, enabling more accurate error handling without requiring complete redesign of the error detection system.
2Reliability
If padding adjustments are made based on spoofing error length indication to improve data transmission reliability, then the processing complexity increases
Solution Approach 1:
The spoofing error length indicator provides preliminary information about the nature and extent of spoofing errors before the actual data processing occurs. This allows the receiver to pre-adjust padding and processing parameters based on the indicated error length, improving reliability while managing complexity through advance preparation.
Solution Approach 2:
The system dynamically changes processing parameters such as padding length and error correction thresholds based on the spoofing error length indicator. This parameter adaptation allows the system to optimize reliability for different error conditions without requiring a completely complex processing architecture for all possible scenarios.
3Productivity
If the spoofing error length indicator field is used to adjust padding, then the data transmission rate improves, but the header size increases
Solution Approach 1:
The spoofing error length indicator provides partial information about the error characteristics rather than complete detailed information. This partial action approach improves transmission rate by providing sufficient information for error handling without the overhead of comprehensive error description, thus limiting the header size increase.

AI summary
Some demonstrative embodiments include apparatuses, devices, systems and methods of communicating an Enhanced Directional Multi-Gigabit (DMG) (EDMG) Orthogonal Frequency-Division Multiplexing (OFDM) Physical layer (PHY) Protocol Data Unit (PPDU). For example, an EDMG station (STA) may be configured to generate an EDMG OFDM PPDU including at least a non-EDMG header (L-Header), an EDMG header, and a data field, the EDMG header including a spoofing error length indicator field configured to indicate whether or not a spoofing error of the EDMG OFDM PPDU is less than one OFDM symbol duration; and to transmit the EDMG OFDM PPDU over a channel bandwidth in a frequency band above 45 Gigahertz (GHz).
