FRONT-END CIRCUITRY FOR CELLULAR VEHICLE-TO-EVERYTHING (C-V2X) STATIONARY OBJECT DETECTION - A simplified explanation of the abstract

This abstract first appeared for US patent application 17816602 titled 'FRONT-END CIRCUITRY FOR CELLULAR VEHICLE-TO-EVERYTHING (C-V2X) STATIONARY OBJECT DETECTION

Simplified Explanation

The present disclosure relates to apparatus and methods for detecting stationary objects using cellular vehicle-to-everything (C-V2X) technology. One example of the invention is a radio frequency (RF) front-end circuit that includes a directional coupler and a delta switch. The directional coupler has a first port for connecting to an antenna and a second port. The delta switch is connected to the second port of the directional coupler and has a first port connected to the second port, a second port, and a third port for connecting to a receive path for detecting a stationary object. The RF front-end circuit and methods provided allow for simultaneous detection of stationary objects and reception or transmission of C-V2X signals.

• The invention is an RF front-end circuit for C-V2X stationary object detection.
• The circuit includes a directional coupler and a delta switch.
• The directional coupler connects to an antenna and has a second port.
• The delta switch is connected to the second port of the directional coupler.
• The delta switch has a first port connected to the second port, a second port, and a third port for connecting to a receive path.
• The circuit allows for concurrent detection of stationary objects and C-V2X signal reception or transmission.

Potential applications of this technology:

• Enhancing the safety of autonomous vehicles by detecting stationary objects in their vicinity.
• Improving traffic management systems by providing real-time information about stationary objects on the road.
• Enabling communication between vehicles and infrastructure for better coordination and efficiency.

• Improved efficiency of traffic management systems through real-time information sharing.
• Enhanced communication capabilities between vehicles and infrastructure for better coordination and decision-making.

Original Abstract Submitted

Certain aspects of the present disclosure provide apparatus and methods for cellular vehicle-to-everything (C-V2X) stationary object detection. One example radio frequency (RF) front-end circuit generally includes a directional coupler having a first port for coupling to an antenna and having a second port; and a delta switch having a first port coupled to the second port of the directional coupler, having a second port, and having a third port for coupling to a receive path for detection of a stationary object. The RF front-end circuit and methods for C-V2X stationary object detection may allow for concurrent (i) stationary object detection and (ii) C-V2X signal reception or transmission.
