    Abstract: Disclosed embodiments include technologies for managing co-existence among multiple Vehicle-to-Everything (V2X) Radio Access Technologies (RATs) through the setting of a Network Allocation Vector (NAV). MAC layer frame headers contain a duration field that specifies a transmission interval during which a shared channel will be occupied by a particular V2X RAT. The NAV indicates the time period intended to be held for the particular V2X RAT, and acts as an indication for how long stations implementing different V2X RATs must abstain from accessing the shared medium. Stations listen on the shared medium to obtain the MAC layer frame, read the duration field, and set their NAV indicators accordingly. Other embodiments are described and/or claimed.

    Abstract: Herein is disclosed a vehicle sensor-data sharing device, comprising one or more processors configured to receive sensor information representing sensor data output from the one or more sensors of a first vehicle; determine a reliability indicator indicating the reliability of the received sensor information; determine from the received sensor information a criticality indicator indicating the criticality of the received sensor information for the first vehicle; select a data sharing level based on the criticality indicator and the reliability indicator; and generate a message comprising observation information or a request for observation information, wherein the observation information corresponds to sensor information according to the data sharing level.
