Simultaneous reception of vehicle-to-everything (V2X) messages over multiple channels in multi-channel V2X networks
First Claim
1. A method comprising:
- detecting a presence of an interference signal on a channel of a Vehicle-to-Everything (V2X) radio which obscures payload data that is included in a V2X message received via the channel;
determining that a source of the interference signal present on the channel is both on-board the V2X radio and off-board the V2X radio and that a type of the interference signal is combination interference;
canceling out the interference signal from the V2X message to generate a modified version of the V2X message including the payload data which is substantially unobscured by the interference signal by;
applying a self-interference cancellation technique to cancel out any self-interference from the V2X message;
applying an adjacent-channel interference cancellation technique to cancel out any adjacent channel interference from the V2X message; and
determining an execution order to cancel out the self-interference and the adjacent channel interference from the V2X message based on one or more order determination factors; and
providing the modified version of the V2X message to a vehicle component so that the vehicle component provides its functionality based on the payload data and not the interference signal.

Abstract
The disclosure describes embodiments for reducing interference for wireless vehicular messages. In some embodiments, a method includes detecting a presence of an interference signal on a channel of a Vehicle-to-Everything (V2X) radio which obscures payload data that is included in a V2X message received via the channel. The method includes determining a source of the interference signal present on the channel. The method includes canceling out the interference signal from the V2X message using a cancellation sequence selected based on the source to generate a modified version of the V2X message including the payload data which is substantially unobscured by the interference signal. The method includes providing the modified version of the V2X message to a vehicle component so that the vehicle component provides its functionality based on the payload data and not the interference signal.

11. A system comprising:
a processor communicatively coupled to a Vehicle-to-Everything (V2X) radio and a non-transitory memory, wherein the V2X radio is operable to receive a V2X message on a channel of the V2X radio and the non-transitory memory stores computer code that is operable, when executed by the processor, to cause the processor to; detect a presence of an interference signal on the channel of the V2X radio which obscures payload data that is included in the V2X message received via the channel; determine that a source of the interference signal present on the channel is both on-board the V2X radio and off-board the V2X radio and that a type of the interference signal is combination interference; cancel out the interference signal from the V2X message to generate a modified version of the V2X message including the payload data which is substantially unobscured by the interference signal by; applying a self-interference cancellation technique to cancel out any self-interference from the V2X message; applying an adjacent-channel interference cancellation technique to cancel out any adjacent channel interference from the V2X message; and determining an execution order to cancel out the self-interference and the adjacent channel interference from the V2X message based on one or more order determination factors; and provide the modified version of the V2X message to a vehicle component so that the vehicle component provides its functionality based on the payload data and not the interference signal. - View Dependent Claims (12, 13, 14, 15)

16. A computer program product embodied on a non-transitory computer readable medium comprising instructions that, when executed by a processor, causes the processor to perform operations comprising:
-
detecting a presence of an interference signal on a channel of a Vehicle-to-Everything (V2X) radio which obscures payload data that is included in a V2X message received via the channel; determining that a source of the interference signal present on the channel is both on-board the V2X radio and off-board the V2X radio and that a type of the interference signal is combination interference; canceling out the interference signal from the V2X message to generate a modified version of the V2X message including the payload data which is substantially unobscured by the interference signal by; applying a self-interference cancellation technique to cancel out any self-interference from the V2X message; applying an adjacent-channel interference cancellation technique to cancel out any adjacent channel interference from the V2X message; and determining an execution order to cancel out the self-interference and the adjacent channel interference from the V2X message based on one or more order determination factors; and providing the modified version of the V2X message to a vehicle component so that the vehicle component provides its functionality based on the payload data and not the interference signal. - View Dependent Claims (17, 18, 19, 20)
