A communication device, notably for motor vehicles, including a transmission system equipped with a light source designed to emit an initial light beam, the transmission system being configured for generating a first light beam polarized in a first direction starting from the initial light beam, the transmission system furthermore including a modulator of the direction of polarization of the first polarized light beam in such a manner as to transmit information, the device furthermore including a receiver system configured for detecting the first polarized light beam when it is polarized in the first direction and for transmitting the information.

Various aspects related to a platooning group in a V2V and/or V2X network are described. In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus maybe a first UE configured to transmit a first message to announce an existence of the platooning group. In one configuration, the first UE may receive, in response to the first message, a second message indicating a request to join the platooning group from a second UE. The first UE may allow or deny the second UE to join the platooning group based on the second message. In another aspect, the apparatus maybe a first UE configured to receive a first message indicating an existence of a platooning group. The first UE may be configured to decode a portion of the first message, and determine whether the platooning group is a private group based on the decoding.

A method, a system, and a computer program product may be provided for providing traffic data to a client device. The system may receive from the client device, a request for traffic data corresponding to road segments of at least one map area, said request identifying the at least one map area and determine road segment identifiers corresponding to each of the road segments of the at least one map area and determine traffic data for at least a portion of the road segment identifiers, said traffic data obtained from a traffic data source. The system may further determine a plurality of traffic ranges based on the obtained traffic data and generate a bloom filter set, each bloom filter of the bloom filter set corresponding to a traffic range of the plurality of traffic ranges, wherein each bloom filter encodes road segment identifiers corresponding to the respective traffic range.

An annunciator system annunciates a mode of a platoon operation being performed between first and second platooning vehicles travelling cooperatively in accordance with a selected mode of the platoon operation. First and second visual indicators generate first and second visual signals having different colors based on visual indicator command signals generated by an annunciator control unit that operates to generate the first and second visual indicator command signals based on a determined mode of the platoon operation being performed between the associated first and second platooning vehicles. The visual annunciator system may be installed on the rear of platooning capable commercial vehicles in an unambiguous location so that it is not confused with other vehicle lamps, and is of a low intensity that does not shine directly at following traffic. The annunciator system generates two different visual colors that may be illuminated and/or flashed to encode the platoon operating mode.

Certain aspects of the present disclosure provide techniques for sidelink communication. A method that may be performed by a user equipment (UE) includes selecting a modulating and coding scheme (MCS) and a transmission power based on a configured dependency between one or more candidate MCSs and one or more candidate transmission powers, and transmitting, via a sidelink channel, one or more frames using the selected MCS and the selected transmission power.

An example embodiment of the invention provides a beacon for providing instructions to an autonomous agent. The beacon comprises an audio or visual output arrangement which is configured to output an audio or visual machine-readable signal. The machine-readable signal is configured to provide an instruction to the autonomous agent. The audio or visual output arrangement is configured to provide the output such that the machine-readable signal is, at least partially, inaudible, invisible, or incomprehensible to humans.

Disclosed are a vehicle warning method and apparatus. The method includes: acquiring real-time information of a vehicle, and determining that an anomaly happens to the vehicle; and sending anomaly information of the vehicle to a nearby terminal by means of short-range wireless communication. In the embodiments of the present disclosure, the short-range wireless communication is adopted, which is convenient and fast, has low costs, is easy to be popularized, and does not depend on 3G/4G or GPS.

The disclosure includes embodiments for improving driving commands for vehicular end-to-end driving. In some embodiments, a method for a connected vehicle includes receiving command data describing one or more driving commands for the connected vehicle. The method includes correcting the one or more driving commands to generate modified command data that describes one or more modified driving commands. The one or more modified driving commands control an operation of the connected vehicle to satisfy a trajectory safety requirement. The method includes modifying an operation of a vehicle control system of the connected vehicle based on the modified command data so that the connected vehicle operates based on the one or more modified driving commands.

A method for operating a traffic monitoring device. A sensor signal is provided by a sensor device of the traffic monitoring device is first of all read in. An item of information is then generated using the sensor signal. Finally, the information is output to an interface to at least one vehicle.

Embodiments disclosed herein relate to methods and apparatus for determining whether a wireless device should perform validation of one or more of a pool of un-validated messages. The method, in a first wireless device, which is one of a plurality of wireless devices located in a geographical area associated with a wireless communications network, for determining whether to perform validation of one or more of a pool of un-validated messages, each addressed to one of the plurality of wireless devices; comprises obtaining respective weightings associated with each of the plurality of wireless devices; and selecting an active list of one or more wireless devices from the plurality of wireless devices, based on the respective weightings associated with each of the plurality of wireless devices. The method further comprises responsive to the active list comprising the first wireless device, performing validation of the one or more of the pool of un-validated messages.
