V2x Packet Prioritization And Control Techniques
Aspects of the disclosure relate to mechanisms for a vehicle-to-everything (V2X) device to prioritize communication from other nearby V2X devices and to selectively process packets from the other nearby V2X devices based on the assigned priorities. The V2X device may measure one or more performance factors of the V2X device, and select one or more other nearby V2X devices to receive and process packets therefrom based on the performance factors and the priorities assigned to the other V2X devices. The V2X device may then ignore any packets received from non-selected V2X devices to reduce and/or control the receive packet flow rate. The performance factors may further be utilized to control one or more transmission characteristics, such as the transmit power and transmit packet flow rate.

USPTO Full Text Publication >
- 1. A method for vehicle-to-everything (V2X) wireless communication at a first V2X device, comprising:
establishing a set of one or more nearby V2X devices capable of V2X communication with the first V2X device; assigning a respective priority to each of the one or more nearby V2X devices; identifying a subset of the set based, at least in part, on the assigned respective priorities and at least one performance factor of the first device; and limiting processing of packets received from the one or more nearby V2X devices to the packets received from the one or more nearby V2X devices in the subset.
- 16. A first vehicle-to-everything (V2X) device for V2X wireless communication, comprising:
a processor; a transceiver communicatively coupled to the processor; and a memory communicatively coupled to the processor, wherein the processor is configured to:
establish a set of one or more nearby V2X devices capable of V2X communication with the first V2X device;
assign a respective priority to each of the one or more nearby V2X devices;
identify a subset of the set based, at least in part, on the assigned respective priorities and at least one performance factor of the first device; and
limit processing of packets received from the one or more nearby V2X devices to the packets received from the one or more nearby V2X devices in the subset.
- 26. A first cellular vehicle-to-everything (V2X) device for V2X wireless communication, comprising:
means for establishing a set of one or more nearby V2X devices capable of V2X communication with the first V2X device; means for assigning a respective priority to each of the one or more nearby V2X devices; means for identifying a subset of the set based, at least in part, on the assigned respective priorities and at least one performance factor of the first device; and means for limiting processing of packets received from the one or more nearby V2X devices to the packets received from the one or more nearby V2X devices in the subset.
