ENHANCED PHYSICAL STRUCTURE FOR LTE V2V COMMUNICATIONS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18341918 titled 'ENHANCED PHYSICAL STRUCTURE FOR LTE V2V COMMUNICATIONS

Simplified Explanation

The patent application describes a method for wireless communication between vehicles using a modified LTE physical channel.

• The physical channel is created by modifying an existing LTE sidelink channel.
• The modification involves increasing the subcarrier spacing, reducing the symbol duration, and reducing the FFT size.
• These modifications enable the implementation of the vehicle-to-vehicle (V2V) physical channel without significant changes to the LTE standard.

Potential applications of this technology:

• Improved communication between vehicles on the road.
• Enhanced safety features in autonomous vehicles.
• Efficient coordination and cooperation between vehicles in traffic.

Problems solved by this technology:

• Overcoming the challenges of high mobility propagation conditions in vehicle-to-vehicle communication.
• Ensuring robust and reliable communication between vehicles in dynamic traffic scenarios.
• Minimizing the need for extensive modifications to existing LTE standards.

Benefits of this technology:

• Increased safety on the road through improved vehicle-to-vehicle communication.
• Enhanced efficiency and effectiveness of autonomous vehicles.
• Compatibility with existing LTE infrastructure, reducing implementation costs and complexity.

Original Abstract Submitted

A vehicle may wirelessly communicate with another vehicle via a physical channel (a vehicle-to-vehicle (V2V) channel) that is robust and reliable under high mobility propagation conditions. The physical channel may be created by modifying an existing long-term evolution (LTE) physical channel, such as an LTE sidelink (SL) channel. For instance, the V2V physical channel may be created by increasing, by a particular factor, the subcarrier spacing of legacy LTE channels (e.g., from 15 kilohertz (kHz) to 30 kHz). Additionally, a symbol duration and a fast Fourier transform (FFT) size for the V2V physical channel may each be reduced by the same factor. Doing so may enable the V2V physical channel to be implemented without significant modifications to other aspects of the LTE standard.
