Abstract: A device is configured to perform a method of device-to-device (D2D) communication in a wireless communication network in accordance with a Long Term Evolution (LTE) standard. The method includes entering an RRC-Idle state or an RRC-Connected state. The method also includes transmitting, in the RRC-Idle state or RRC-Connected state, a D2D discovery signal for receipt by at least one second device in the network. The method further includes receiving, in the RRC-Idle state or RRC-Connected state, at least one D2D discovery signal from the at least one second device in the network.

Abstract: A method for operating a mobile device adapted for device-to-device (D2D) communications includes determining a utilization measure for discovery resources (DRs) allocated for D2D discovery in a communications system, and sending a utilization measure report to an evolved NodeB (eNB) when a reporting criterion is satisfied, wherein the utilization measure report is configured to prompt an adjustment to a number of DRs allocated for D2D discovery when an adjustment condition is met.

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: System and method embodiments for auxiliary content delivery are disclosed. In an embodiment, a method in a transmission point (TP) for auxiliary content delivery includes determining a mobile wireless device capable of auxiliary content delivery to an end device according to predicted movement of the mobile wireless device with respect to the end device. The method also includes encoding content data into a plurality of content data packets such that the content data is recoverable by the end device from a subset of the plurality of content data packets. The method also includes transmitting control data and one or more of the plurality of content data packets to the mobile wireless device when the mobile wireless device is within a first proximity of the TP. The control data provides to the wireless device scheduling information for the retransmission of the content data packets to the end device.

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: A method and system provide determining whether to pursue grant free transmission in accordance with a size of at least one packet in a first buffer of at least one buffer and determining a size of a grant free transport block (GFTB) in accordance with a configuration of radio resources available for grant free transmission in instances where grant free transmission is to be utilized. The method also includes populating the GFTB with first data from at least one of the buffers to produce a populated GFTB and transferring the GFTB from a media access control (MAC) layer to a physical layer (PHY).
