APPARATUS, SYSTEM AND METHOD OF AN ORTHOGONAL FREQUENCY-DIVISION MULTIPLEXING (OFDM) TRANSMISSION OVER A WIDE BANDWIDTH - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240129058 titled 'APPARATUS, SYSTEM AND METHOD OF AN ORTHOGONAL FREQUENCY-DIVISION MULTIPLEXING (OFDM) TRANSMISSION OVER A WIDE BANDWIDTH

Simplified Explanation

The apparatus described in the abstract is designed to parse scrambled data bits of a PPDU (Physical Protocol Data Unit) into two sets of data bits, encode and modulate each set according to different OFDM MCS (Modulation and Coding Scheme), and transmit them over two different frequency bands.

  • Segment parser to parse scrambled data bits of a PPDU into a first plurality of data bits and a second plurality of data bits
  • First baseband processing block to encode and modulate the first set of data bits according to a first OFDM MCS for transmission over the first frequency band
  • Second baseband processing block to encode and modulate the second set of data bits according to a second OFDM MCS for transmission over the second frequency band

Potential Applications

This technology can be applied in wireless communication systems where data needs to be transmitted over multiple frequency bands simultaneously.

Problems Solved

This technology solves the problem of efficiently transmitting data over an aggregated bandwidth comprising multiple frequency bands.

Benefits

The benefits of this technology include increased data transmission efficiency and improved utilization of available frequency bands.

Potential Commercial Applications

One potential commercial application of this technology is in multi-band Wi-Fi routers or access points for improved data transmission performance.

Possible Prior Art

Prior art may include similar techniques used in multi-band communication systems or OFDM-based wireless technologies.

Unanswered Questions

How does this technology handle interference between the two frequency bands during transmission?

The abstract does not provide details on how the apparatus mitigates interference between the two frequency bands.

What impact does encoding and modulating data according to different OFDM MCS have on overall system performance?

The abstract does not discuss the potential impact of using different OFDM MCS for encoding and modulation on the performance of the system.


Original Abstract Submitted

for example, an apparatus may include a segment parser to parse scrambled data bits of a ppdu into a first plurality of data bits and a second plurality of data bits, the ppdu to be transmitted in an ofdm transmission over an aggregated bandwidth comprising a first channel in a first frequency band and a second channel in a second frequency band; a first baseband processing block to encode and modulate the first plurality of data bits according to a first ofdm mcs for transmission over the first channel in the first frequency band; and a second baseband block to encode and modulate the second plurality of data bits according to a second ofdm mcs for transmission over the second channel in the second frequency band.
