    Abstract: A method includes determining a first subframe on which to transmit a first downlink control information (DCI) message and determining a second subframe on which to transmit a first information. The method also includes determining a delay between the first subframe and the second subframe and transmitting, by a communications controller to a user equipment (UE), the second subframe in accordance with the delay.

    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.

    Abstract: An efficient random access procedure is provided for reduced control overhead of connections in random access systems. A base station transmits one or more synchronization signal (SS) blocks. A UE detects and determines a preferred SS block. The UE transmits multiple random access signals (e.g., PRACH signals) in a RACH occasion. Each PRACH signal is transmitted on a different beam and includes a RACH preamble. The base station receives one or more of the PRACH signals. The RACH occasion and optionally the RACH preamble identify the preferred SS block. The base station determines a preferred PRACH signal. The base station sends a RAR to the UE using the transmit beam of the preferred SS block. The RAR indicates the preferred PRACH signal and an uplink resource allocation. The UE receives the RAR and transmits a message using the transmit beam of the preferred PRACH signal and the uplink resource allocation.

    Abstract: When at least one of device-to-device UEs in connections of a group of D2D UEs is outside of the coverage area of mobile network of an access point, an information exchange mechanism established directly between the D2D UEs without involving a third party, is provided. A Sidelink Control Information (SCI) message type comprises one or more format flags indicating the respective resource allocation format, obtaining a first SCI message, adjusting a size of the first SCI message based on the determined size, and transmitting the adjusted first SCI message by a first UE in a Physical Sidelink Control Channel (PSCCH) to one or more second UEs for establishing the D2D communication link.

    Abstract: A device is configured to perform a method of wireless communication in a wireless communication network. The method includes receiving, from a communications controller, a device-to-device (D2D) subframe configuration to communicate with one or more second wireless devices, the subframe configuration indicating one or more subframes in which to transmit a D2D signal or receive one or more D2D signals. The method also includes receiving, from the communications controller, scheduling information to transmit a first signal to the communications controller on a subframe indicated by the D2D subframe configuration. The method further includes prioritizing the transmission of the first signal over a transmission of the D2D signal or a reception of the one or more D2D signals, and transmitting the first signal.
