HYBRID ORTHOGONAL FREQUENCY DIVISION MULTIPLEXING - A simplified explanation of the abstract
This abstract first appeared for US patent application 17643540 titled 'HYBRID ORTHOGONAL FREQUENCY DIVISION MULTIPLEXING
Simplified Explanation
The patent application describes techniques for hybrid modulation and demodulation, specifically for multiplexing and demultiplexing different waveform types.
- The method involves receiving a time-domain waveform from a transmitting entity and converting it to a frequency domain.
- It identifies specific time and frequency resources associated with different information in an orthogonal frequency domain multiplexing (OFDM) resource grid.
- The first set of resources is decoded to generate the first information, which may be precoded with an orthogonal time frequency space (OTFS) modulation.

Original Abstract Submitted
Certain aspects of the present disclosure provide techniques for hybrid modulation and demodulation, which may include multiplexing and demultiplexing different waveform types. An example method includes receiving a time-domain waveform from a transmitting entity and converting the time-domain waveform to a frequency domain. The method also includes identifying a first set of time and frequency resources associated with converted first information and a second set of time and frequency resources associated with second information in time and frequency resources of an orthogonal frequency domain multiplexing (OFDM) resource grid in a time-frequency domain. The method further includes decoding the first set of time and frequency resources to generate first information from the converted first information. For certain aspects, the first information may be precoded with an orthogonal time frequency space (OTFS) modulation.
