Abstract: A communication device mounted on a vehicle, e.g., On-Board Unit (OBU), communicates collision related information to other road entities, e.g., other vehicles or roadside units (RSUs) or a server, after a collision is detected. The OBU may temporarily store basic safety messages (BSMs) (and optionally sensor data) for a predesignated number of seconds before discarding the BSMs (and optionally sensor data) on a continuing basis. When a collision is detected, the OBU sends a report, e.g., to a server, with the stored BSMs (and optionally sensor data) to a server. After a collision detection, the OBU may send a request to other vehicles to upload relevant collision related information. Additionally, if a first vehicle detects the collision of a second vehicle, the first vehicle may communicate collision related information to other entities and a server.

Abstract: A vehicle control unit (VCU) or other vehicle device to accept a reduced number of messages from a sender for processing rather than having the sender transmit messages less often when a communication channel is crowded. The overall number of messages that need to be processed after accepting the messages stays the same, but the number of messages accepted per sender per time interval is reduced.

Abstract: Implementations disclosed describe techniques and systems that improve wireless connectivity between devices that support multiple operation modes, by monitoring a quality of the established wireless connection and performing a change of the operation mode in response to changing conditions. The disclosed techniques include obtaining metrics characterizing quality of the wireless connection, identifying a utility function that is specific to an application supported by the wireless connection, computing multiple values of the utility function for various operation modes, based on the obtained metrics, and initiating a change of the operation mode based on a comparison of the computed utility values.

Abstract: A device may receive geolocation data associated with a user device in a first cell region, and may determine a location of the user device. The device may determine whether the user device is located in an overlapping region or a non-overlapping region between the first cell region and a second cell region, and may calculate a velocity of the user device. The device may estimate a trajectory of the user device, and may calculate a first distance associated with the user device entering the overlapping region. The device may calculate a second distance associated with the user device exiting the overlapping region, and may determine a first time period to travel the first distance. The device may determine a second time period to travel the second distance, and may determine a handover time period based on the first time period and the second time period.

Abstract: Embodiments of the present disclosure are directed to systems and methods for polarization division multiple access. A polarized antenna system having a plurality of differently-polarized antennas is envisioned for wirelessly communicating with a plurality of user devices in a wireless network environment. Each polarized pair of antenna elements, using a particular frequency, will transmit signals using a polarization-frequency pair and a base station will instruct user devices which polarization-frequency pair they should tune to for processing the appropriate downlink signal. Using OFDMA with a polarized antenna system increases capacity without the need for deploying additional base stations.

Abstract: In one embodiment, a RF signal repeater switchable between SISO and MIMO comprises: a controller; a first transmitter path switchably coupled to first donor and coverage antennas; a second transmitter path switchably coupled to second donor and coverage antennas; a first receiver path switchably coupled to the first donor and coverage antennas; a second receiver path switchably coupled to the second donor and coverage antennas.

Abstract: Responsive to matching a site prefix to IPv6 network traffic from clients, the traffic as intended, and responsive to not matching the site prefix, classifying the corresponding traffic as unintended. An initial rate of packet occurrence and predict load caused by intended traffic and predicting load caused by unintended traffic is calculated, based on an initial rate of packet occurrence. The predicted traffic loads are fed back by configuring behavior of network modules according to the predictions of intended traffic load and unintended traffic load. Packet processing traffic at the network modules is based on traffic classification from the outcome of the AI-neuron.
