Negative Acknowledgment (NACK) Design and Block Acknowledgement Modification - A simplified explanation of the abstract

This abstract first appeared for US patent application 18600572 titled 'Negative Acknowledgment (NACK) Design and Block Acknowledgement Modification

The patent application describes methods, systems, and computer-readable medium for detecting a reception opportunity of a physical layer protocol data unit (PPDU) scheduled for transmission, decoding the preamble of the PPDU, detecting failed reception of one or more media access control (MAC) PDUs (MPDUs), and preparing a Negative Acknowledgment (NACK) message in response to the detection of failed reception.

• Detection of reception opportunity of a PPDU
• Decoding the preamble of the PPDU
• Detection of failed reception of one or more MPDUs
• Preparation of a NACK message for transmission to the transmitter

Potential Applications: - Wireless communication systems - Error detection and correction mechanisms - Data transmission reliability enhancement

Problems Solved: - Improving data transmission reliability - Efficient error detection in wireless communication - Enhancing overall system performance

Benefits: - Increased data transmission accuracy - Enhanced communication reliability - Improved system efficiency

Commercial Applications: Title: "Enhancing Wireless Communication Reliability with NACK Message Preparation" This technology can be applied in various industries such as telecommunications, IoT devices, and networking equipment to improve data transmission reliability and overall system performance.

Questions about the technology: 1. How does the preparation of a NACK message improve data transmission reliability? 2. What are the potential implications of using NACK messages in wireless communication systems?

Original Abstract Submitted

Disclosed are methods, systems, and computer-readable medium to perform operations including detecting a reception opportunity of a physical layer protocol data unit (PPDU) scheduled to be transmitted by a transmitter, where the PPDU includes a preamble and one or more media access control (MAC) PDUs (MPDUs); decoding the preamble of the PPDU; detecting that reception of the one or more MPDUs has failed; and in response to the detecting, preparing a Negative Acknowledgment (NACK) message for transmission to the transmitter.
