ENHANCED PHYSICAL STRUCTURE FOR LTE V2V COMMUNICATIONS - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240340204 titled 'ENHANCED PHYSICAL STRUCTURE FOR LTE V2V COMMUNICATIONS
The abstract of the patent application describes a method for vehicles to wirelessly communicate with each other using a robust and reliable physical channel, specifically for high mobility propagation conditions. This channel is created by modifying an existing LTE physical channel, such as an LTE sidelink channel, to increase subcarrier spacing and reduce symbol duration and FFT size.
- Increase subcarrier spacing of legacy LTE channels to create the V2V physical channel
- Reduce symbol duration and FFT size by the same factor for implementation
- Enable V2V physical channel without significant modifications to LTE standard
Potential Applications: - Enhanced vehicle-to-vehicle communication - Improved safety and efficiency on the road - Support for autonomous driving technologies
Problems Solved: - Ensuring reliable communication between vehicles under high mobility conditions - Adapting existing LTE technology for V2V communication
Benefits: - Increased safety on the road - Enhanced communication capabilities for connected vehicles - Seamless integration with existing LTE infrastructure
Commercial Applications: Title: "Advanced Vehicle-to-Vehicle Communication Technology for Safer Roads" This technology can be utilized in the automotive industry for developing advanced driver assistance systems, autonomous vehicles, and smart transportation solutions. It has the potential to revolutionize the way vehicles communicate with each other on the road, leading to safer and more efficient transportation systems.
Questions about the technology: 1. How does this technology improve communication between vehicles in high mobility conditions? 2. What are the key advantages of using an LTE-based physical channel for V2V communication?
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.
