SIGNALING PARAMETERS FOR UW-OFDM WAVEFORM - A simplified explanation of the abstract

This abstract first appeared for US patent application 17456364 titled 'SIGNALING PARAMETERS FOR UW-OFDM WAVEFORM

Simplified Explanation

This patent application is about UW-OFDM waveform techniques, which involve systems and methods for transmitting and receiving signals in an underwater environment. Here is a simplified explanation of the abstract:

The patent application describes a system for underwater communication using UW-OFDM waveform techniques.
A user equipment (UE) receives parameters for the UW-OFDM waveform from a base station.
The UE then receives a downlink transmission from the base station using the UW-OFDM waveform.
The location of redundant subcarriers in the UW-OFDM waveform is determined based on the frequency resources allocated for the UE or a combination of frequency resources allocated to multiple UEs.

Potential Applications

This technology has potential applications in various underwater communication systems, including:

Underwater data transmission for scientific research and exploration.
Underwater surveillance and monitoring systems.
Underwater robotics and autonomous vehicles.
Underwater oil and gas exploration and production.
Underwater military and defense operations.

Problems Solved

The UW-OFDM waveform techniques described in this patent application address several challenges in underwater communication, including:

Limited bandwidth and high attenuation of signals in underwater environments.
Interference from other underwater devices and noise.
The need for efficient and reliable communication in harsh underwater conditions.
Optimizing the use of frequency resources for multiple users in an underwater network.

Benefits

The use of UW-OFDM waveform techniques offers several benefits for underwater communication systems:

Improved data transmission rates and reliability in underwater environments.
Efficient use of limited frequency resources for multiple users.
Enhanced resistance to interference and noise.
Compatibility with existing underwater communication systems.
Facilitation of various underwater applications, including research, surveillance, and exploration.

Original Abstract Submitted

This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for UW-OFDM waveform techniques. A UE may receive, from a base station, an indication of one or more parameters for the UW-OFDM waveform. The UE may subsequently receive, from the base station, a downlink transmission having the UW-OFDM waveform based on the one or more parameters. A location of redundant subcarriers for the UW-OFDM waveform may be based on at least one of frequency resources allocated for the UE or a combination of the frequency resources allocated to multiple UEs.
