    Abstract: Embodiments are provided to support device-to-device (D2D) communications in a time-division duplexing (TDD) communications system, and ensure that D2D discovery signals are transmitted by user devices on an uplink subframe when there is a TDD frame configuration change. In an embodiment, a user device receives form the network a TDD frame configuration selected from a set of available TDD frame configurations according to the TDD configuration. The device further receives a D2D discovery configuration for a discovery time interval. The user device then allocates a transmission resource a D2D discovery signal within the discovery time interval according to the D2D discovery configuration. The user device is also configured to receive from another device a second D2D discovery signal during the discovery time interval in accordance with the TDD configuration and the D2D discovery configuration.

    Abstract: According to one aspect of the present disclosure, there is provided a method, by a virtual network function, that includes: receiving a first request from a user equipment (UE), the first request including first parameters and a first token, the first token being a vector value corresponding to a session state for the UE; determining the session state for the UE according to the first token; programming network resources according to the session state, the programming updating states of the network resources, wherein the session state for the UE is updated when the states of the network resources are updated; producing a second token corresponding to the updated session state for the UE; storing the updated session state and the second token; and transmitting the second token to the UE.

    Abstract: Embodiments are provided herein for determining a synchronizing master for device-to-device (D2D) communication in a cellular network environment. In an embodiment, a user equipment (UE) receives a discovery signal comprising a timing reference, and determines a transmitter of the discovery signal. In accordance with the determination of the transmitter of the discovery signal, the UE performs one of synchronizing to the timing reference in the discovery signal and transmitting a second discovery signal. The UE performs the synchronizing to the timing reference if the transmitter of the discovery is a cellular network. Alternatively, the UE transmits the second discovery signal upon determining that the transmitter of the discovery signal is a second UE that is out of coverage of a cellular network.

    Abstract: It is possible to reduce latency and/or overhead when performing a platoon handover by using the leading vehicle in the platoon to communicate handover requests and/or initial resource requests (e.g., random access transmissions) on behalf of trailing vehicles in the platoon. In one example, a leading vehicle in a platoon communicates a handover request to a source AP to request handover of the entire platoon from the source AP to a target AP. In such an example, the source AP then communicates handover commands to each vehicle in the platoon without receiving separate handover requests from the trailing vehicles, thereby reducing overhead in the access network. The handover commands notify the trailing vehicles of the handover, and may be sequentially communicated to the trailing vehicles based on their order in the platoon.
