    Abstract: A method performed by a vehicle to everything application enabler (VAE) client of a wireless device for using a service in a wireless communication network for vehicle to anything (V2X) wireless devices. The VAE client receives, from a V2X application specific client, a V2X message of a service with a service ID; and determines a network node for receiving an uplink V2X message based on the service ID. The VAE client further transmits the uplink V2X message to the determined network node with the service ID.

  • Publication number: 20210360721
    Abstract: A wireless device (100) is configured for dual mode V2X communications over multiple short range radio interfaces. The wireless device (100) is configured to transmit ITS messages over a first short range radio interface configured to operate according to a first communication standard (e.g. PC5 or IEEE 802.11p), and to receive ITS messages over both the first short range radio interface and a second short radio interface configured to operate according to a second communication standard. Implementing the transmitter chain of only one technology, either PC5 or IEEE 802.11p, at each wireless device (100) reduces complexity and mitigates co-channel and adjacent channel interference that is caused by uncoordinated and concurrent transmissions of different technologies from the same wireless device. Implementing receiver chains for both PC5 and 802.11p allows the wireless device (100) to receive signals in the ITS frequency band regardless of which technology the transmitting device is using.

  • Patent number: 8942188
    Abstract: The present invention relates to a method of reducing beacon collision probability in a communication network supporting control channels comprising beacon periods divided into beacon slots, each beacon period being followed by a contention period. In the method a communication device (101) operating in the communication network first chooses (503) an available beacon slot for transmission of a first type of beacon for exchanging network topology information with other communication devices operating in the communication network. Then the communication device transmits (515) a beacon of a second type comprising an identifier of the communication device and the chosen beacon slot for the transmission of the beacon of the first type, the beacon of the second type being transmitted in the contention period.

  • Patent number: 8625546
    Abstract: This invention defines a medium access protocol for the support of mesh networking in wireless communications. It defines a phase for intra-cell and a phase for inter-cell traffic. During the inter-cell traffic a beacon phase is used for the reservation of transmissions. In this phase also information about the mesh topology is included and parallel transmission are supported. Even though this medium access protocol is intended to be proposed in standardization of IEEE 802.11 mesh networks (802.11) it could be used in any wireless mesh network.

  • Patent number: 8570868
    Abstract: A congestion control method for a communication system supporting layered radio channel structure for communication between at least a first communication device and a second communication device that offers a first and second types of service with corresponding first and second priority orders. The messages between devices include a preamble and a payload with each message being separated by at least a minimum allowable period. The first communication device generates a physical layer message pertaining to the first type of service, senses the radio channel idle for at least a period corresponding to the minimum allowable period between two messages, and transmits the physical layer message including a preamble indicative of the type of service the message pertains. The content of the preamble is detected by the second communication device within a communication range irrespective of the decoding state of the payload of the transmitted message.
