In one aspect, an in-vehicle device is provided that includes a sensor configured to detect a vehicle characteristic indicative of the vehicle being in proximity to a location associated with a movable barrier operator. The in-vehicle device includes communication circuitry to communicate an open command to the movable barrier operator that causes the movable barrier operator to open a movable barrier connected to the movable barrier operator. A memory is configured to store a vehicle arrival condition indicative of whether the vehicle arrived at the location associated with the movable barrier operator. A processor is configured to determine satisfaction of the vehicle arrival condition and, upon the vehicle arrival condition not being satisfied, cause the communication circuitry to communicate a close command to the movable barrier operator that causes the movable barrier operator to close the movable barrier.

A road-side network node for operating in a cell-supported radio communications network is provided. The road-side network node comprises a processor, a memory, a radio module, and an antenna. The road-side network node is configured to: determine or receive a gap information indicating a transmission gap period on a sidelink radio channel; and transmit an energy signature via the sidelink radio channel within the transmission gap period.

A method and apparatus are disclosed. In an example from the perspective of a first device, the first device performs sidelink communication with one or more destinations. The first device receives and/or selects a sidelink grant associated with a sidelink transmission. Responsive to the sidelink grant, the first device selects a first destination of the one or more destinations based upon a report signaling. The first device performs the sidelink transmission associated with the sidelink grant to the first destination.

The present application discloses a method of issuing pseudonymous authorisation tickets to nodes of a cooperative ITS, for signing messages, comprising: receiving a ticket request from a node in an authorisation server, and sending a validation request to an enrolment server, conducting a validity check in the enrolment server, and, when the validity check is passed, incrementing a counter value of a counter assigned to an account at an account server enrolled with the enrolment server for the requesting node, sending a validation message to the authorisation server, and issuing a pseudonymous authorisation ticket from the authorisation server to the requesting node, repeating the aforementioned steps until a predetermined charging period expires, and, upon expiry, sending, from the enrolment server to the authorisation server, said counter value, and sending a charging request calculated from said counter value from the authorisation server to the account server for charging said account.

A handover method for managing WBSS vehicle network managed by a WESS-CM includes: recognizing that a vehicle enters an overlapped area between first and second WBSSs; sending, by the first WBSS, a handover recommend request to the WESS-CM; confirming with the second WBSS, by the WESS-CM, whether handover is possible; responding to the WESS-CM, by the second WBSS, the availability of the handover after allocating communication resources; sending, by the WESS-CM, a handover recommend response to the first WBSS; transmitting, by the first WBSS, a handover request message to the vehicle; performing the handover, by the vehicle, by performing reassociation with the second WBSS; and periodically broadcasting, by the vehicle, basic safety message using a T-slot in shared control channel and a T-slot in BSM channel for the second WBSS, while the vehicle is located in the overlapped area.
