Abstract: The disclosure relates to technology for a base station to signal user equipment to monitor a narrowband control channel in a wideband system. The base station sends a configuration signaling to configure the user equipment including a designation of subframe(s). The base station then determines whether to signal the user equipment to monitor the subframe(s) using one of a narrowband bandwidth and a system bandwidth. In response to the base station signaling the user equipment to monitor the narrowband bandwidth, the base station communicates with the user equipment using the narrowband bandwidth. In response to the base station signaling the user equipment to monitor the system bandwidth, the base station sends a probe message within the narrowband bandwidth to the user equipment, where the probe message signals to the user equipment to begin monitoring the system bandwidth and to communicate with the user equipment using the system bandwidth.

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: Embodiments are provided to implement a time/power/frequency hopping scheme for device-to-device (D2D) discovery. The embodiments improve the UE detection of D2D discovery signals from neighboring UEs and account for large number of UEs' discovery signals. This is achieved by having neighboring UEs transmitting at different time instances and at different power levels. Further, neighboring UEs can be configured to transmit on different frequencies. This is achieved by assigning different time/power/frequency sequences to different UEs. An embodiment method includes transmitting, to a UE, parameters a hopping pattern of a first sequence of resources for transmitting a discovery signal by the UE and of a second sequence of resources for receiving a second discovery signal by the UE. The first sequence of resources comprises at least one of a sequence of time instances and a sequence of power levels. The second sequence of resources comprises time instances.
