NGV STA A-MPDU Fixed Parameters Eliminate Negotiation Overhead
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication standards, such as IEEE 802.11, require negotiation of association request and response messages for data frame aggregation, leading to signal processing overhead, time delays, and consumption of transmission bandwidth, which impairs interoperability between devices, especially in fast-changing environments like Next Generation Vehicle-to-Everything (NGV) communications.
Innovation Solution
Configuring wireless communication station (STA) devices with predetermined operational parameters for Aggregate MAC Service Data Unit (A-MSDU) and Aggregate MAC Protocol Data Unit (A-MPDU), allowing direct data frame aggregation without the need for negotiation messages, thereby simplifying interoperability and enhancing data throughput efficiency in NGV applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If negotiation of association request and response messages is performed for data frame aggregation, then interoperability between devices is ensured, but signal processing overhead, time delays, and consumption of transmission bandwidth increase
Solution Approach 1:
The patent applies preliminary action by pre-configuring fixed operational parameters for A-MSDU and A-MPDU operations before actual data transmission. This eliminates the need for real-time negotiation of association request and response messages, thereby reducing time delays while ensuring interoperability through standardized predetermined parameters.
Solution Approach 2:
The patent extracts and removes the negotiation signaling overhead from the data transmission process. By using fixed predetermined parameters for frame aggregation, the complex negotiation exchange between devices is eliminated, reducing signal processing overhead and freeing up transmission bandwidth for actual data communication.
2Adaptability or versatility
If negotiation of association request and response messages is performed for data frame aggregation, then device compatibility is ensured, but transmission bandwidth is consumed
Solution Approach 1:
The patent applies universality by establishing fixed operational parameters that can be universally applied across different NGV devices. These predetermined parameters for A-MSDU and A-MPDU operations ensure device compatibility without requiring device-specific negotiation, thereby conserving transmission bandwidth for actual data transfer while maintaining broad interoperability.
3Productivity
If data frame aggregation is implemented with negotiation signaling, then data throughput is improved, but signal processing overhead increases
Solution Approach 1:
The patent applies preliminary action by pre-establishing fixed operational parameters for frame aggregation before data transmission begins. This eliminates the need for complex real-time negotiation signaling, reducing signal processing overhead at devices while maintaining the benefits of data frame aggregation for improved throughput efficiency in NGV communications.

AI summary
In an IEEE 802.11bc wireless system, aggregated data frames are communicated between first and second STA devices by configuring the first STA device to assemble and transmit an A-MPDU frame having multiple A-MPDU subframes characterized by a fixed MPDU start spacing parameter and a fixed maximal MPDU length parameter, where the first STA device is configured with the fixed MPDU start spacing parameter and the fixed maximal MPDU length parameter without negotiating association request and response messages, and by configuring the second STA device to assemble and transmit a BA message comprising a BA bitmap identifying the one or more of the multiple A-MPDU subframes which are not successfully received by the second STA device, where the BA bitmap has a size characterized by a fixed buffer size parameter which is configured at the second STA device without negotiating add BA request (ADDBA Request) request and response messages.
