Method and Apparatus for Transmitting PLCP Frame in Wireless Local Area Network System - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240137255 titled 'Method and Apparatus for Transmitting PLCP Frame in Wireless Local Area Network System

Simplified Explanation

The patent application describes a method for transmitting a physical layer convergence procedure (PLCP) frame in a very high throughput (VHT) wireless local area network (WLAN) system. Here are the key points of the innovation:

  • Generating a MAC Protocol Data Unit (MPDU) for transmission to a destination station (STA).
  • Creating a PLCP Protocol Data Unit (PPDU) by adding a PLCP header, including an L-SIG field for legacy STAs and a VHT-SIG field for VHT STAs, to the MPDU.
  • Transmitting the PPDU to the destination STA.
  • Obtaining a constellation applied to some OFDM symbols of the VHT-SIG field by rotating a constellation applied to an OFDM symbol of the L-SIG field.
      1. Potential Applications

- High-speed wireless communication systems - Next-generation WLAN technologies

      1. Problems Solved

      1. Potential Commercial Applications
        1. Optimizing VHT WLAN Systems for High-Speed Data Transmission
      1. Possible Prior Art

No prior art is known at this time.

        1. Unanswered Questions
        1. How does the rotation of the constellation in the VHT-SIG field improve signal transmission efficiency?

The rotation of the constellation in the VHT-SIG field allows for better differentiation and decoding of signals, leading to improved overall transmission efficiency.

        1. What impact does the inclusion of control information for both legacy and VHT STAs have on network performance?

By including control information for both legacy and VHT STAs in the PLCP header, the system can effectively manage and optimize communication with different types of stations, leading to improved network performance and reliability.


Original Abstract Submitted

a method of transmitting a physical layer convergence procedure (plcp) frame in a very high throughput (vht) wireless local area network (wlan) system includes generating a mac protocol data unit (mpdu) to be transmitted to a destination station (sta), generating a plcp protocol data unit (ppdu) by adding a plcp header, including an l-sig field containing control information for a legacy sta and a vht-sig field containing control information for a vht sta, to the mpdu, and transmitting the ppdu to the destination sta. a constellation applied to some of orthogonal frequency division multiplex (ofdm) symbols of the vht-sig field is obtained by rotating a constellation applied to an ofdm symbol of the l-sigfield.
