Abstract: To efficiently use uplink resources while fulfilling latency requirements of low latency services, an access node, a resource pool allocated for contention based transmissions of low latency communication services may be used for transmissions of data services, since an access node providing the resource pool, is caused to send, in response to not being able to decode terminal device identification information from a sensed scheduling request, a stop instruction to terminal devices that are using the resource pool to transmissions of the data services. Further, the terminal device that sent the scheduling request is caused to use the resource pool for transmissions of the low latency service if a response is not received within predetermined time.

Abstract: Systems, methods, and software for managing radio resources for vehicle-to-vehicle (V2V) communications. A geographic area is segmented into zones with a subset of the transmission slots allocated to each of the zones. The subset of the transmission slots allocated to each zone is partitioned into periodic transmission slots assignable to individual vehicles for periodic transmissions and special transmission slots reserved for special transmissions according to a contention-based protocol. A resource manager stores a mapping of transmission slots for each of the zones. When a vehicle enters one of the zones, the resource manager performs a slot assignment for the vehicle from the periodic transmission slots allocated to the zone, and transmits a notification to the vehicle indicating the slot assignment.

Abstract: Autonomous vehicles may communicate with each other to avoid hazards, mitigate collisions, and facilitate the flow of traffic. To enhance such cooperation, it would be highly advantageous if each vehicle were able to determine which vehicle in view corresponds to each communication message, which is generally unknown if a plurality of vehicles are in range. Systems and methods provided herein can enable autonomous vehicles to determine the spatial location of each proximate vehicle by detecting a pulsed localization signal emitted by each of the other vehicles. In addition, each vehicle can transmit a self-identifying code, synchronous with the emitted localization signal, so that other vehicles can associate the proper code with each vehicle. After such localization and identification, the vehicles can then cooperate more effectively in mitigating potential collisions.

Abstract: A method and user node for maintaining a connection with a network node when operating in a multi-carrier mode using a first filter configuration to receive multiple frequency carriers simultaneously for downlink communication. The user node applies a mode switching scheme comprising first intervals for the multi-carrier mode and second intervals for a single carrier mode using a second filter configuration to receive a single carrier for the downlink communication. In this case, the user node switches temporarily from the multi-carrier mode to operate in the single carrier mode during the second intervals according to the mode switching scheme. Thereby the user node is enabled to maintain the connection by receiving messages and/or control signalling from the network node over the single frequency carrier during the second intervals, for example when the multi-carrier mode is highly disturbed by interference.

Abstract: A data transmission acceleration method and related apparatuses are disclosed. A sanding node transmits a plurality of data packets to a receiving node at an initial transmission rate. Each data packet carries a random sequence number and a rolling sequence number. The random sequence number identifies a data part of the data packet, and the rolling sequence number indicates a transmission sequence of the data packet.

The packet loss feedback is generated after the receiving node detects a packet loss event according to a rolling sequence number of a received data packet. The sending node determines a random sequence number of a lost data packet based on the received packet loss feedback. The sending node retransmits a data packet corresponding to the determined random sequence number. The retransmitted data packet carries a new rolling sequence number.

Abstract: A method is described for managing risk messages in a distributed, vehicle-to-vehicle (V2V) safety system that limits broadcast storms during an omnidirectional rebroadcast of risk messages in a range larger than a radio range. A group of self-organized transponders, such as may be in vehicles, broadcasts, in a shared medium, real-time safety messages, using self-assigned time slots in regular, contiguous time intervals. Relative locations of up to four distinct transponders are computed and compared, along with a geographic angle formed by three transponders. Risk messages are not rebroadcast when another vehicle, farther from the originating vehicle, has already rebroadcast the same message. Risk values may be single-digit integers, created by adding sub-risk values responsive to real-time vehicle behavior, traffic, weather, road conditions, and the risk history of a road segment. Risk messages are free of fixed vehicle or transponder identification.

Upon completion of the upload, the device description file is registered, thereby allowing the communications application to display information about the device and to manage data exchange between the industrial device and the client-side application.
