Abstract: A network controller may configure one or more channel state information-reference signal (CSI-RS) configurations for transmitting RSs to user equipments (UEs) for tracking. A CSI-RS configuration may specify a set of CSI-RS resources for transmitting RSs in two consecutive slots. The set of CSI-RS resources may include a plurality of one-port CSI-RS resources configured according to the CSI-RS configuration. The CSI-RS configuration may specify a quasi co-location (QCL) configuration including a set of QCL parameters, where a demodulation reference signal (DMRS) has a QCL relationship with the RS with respect to the set of QCL parameters. The network controller may signal the one or more CSI-RS configurations to UEs.

Abstract: User Equipments (UEs) may be assigned a set of aggregated component carriers for downlink carrier aggregation and/or carrier selection. Some UEs may be incapable of transmitting uplink signals over all component carriers in their assigned set of aggregated component carriers. In such scenarios, a UE may need to perform SRS switching in order to transmit SRS symbols over all of the component carriers. Embodiments of this disclosure provide various techniques for facilitating SRS switching. For example, a radio resource control (RRC) message may be used to signal a periodic SRS configuration parameter. As another example, a downlink control indication (DCI) message may be used to signal an aperiodic SRS configuration parameter. Many other examples are also provided.

Abstract: An apparatus and method are provided for supporting vehicle-to-vehicle communication utilizing a base station. Included is a vehicular network interface configured to receive, from a first subset of a set of vehicles, first messages. The vehicular network interface is further configured to receive composite messages that are generated by a base station based on second messages transmitted by a second subset of the set of vehicles. Also included is circuitry in communication with the vehicular network interface. The circuitry is configured to re-create at least a portion of the second messages based on at least a portion of the first messages and at least a portion of the composite messages.

Abstract: The disclosure relates to technology for assisting a wireless a communication device to acquire access to a millimeter-wave access point (mmW AP). In some embodiments, an angular direction from a mobile wireless communication device to the mmW AP is determined. In some embodiments, the mobile wireless communication device receives information from a wireless network that helps the mobile wireless communication device determine the angular direction. In some embodiments, the signals between wireless network and mobile wireless communication device are below 6 GHz. In some embodiments, the wireless network provides the mobile wireless communication device with the angular direction. Therefore, the mobile wireless communication device is able to configure an antenna to receive and/or transmit a beam in a direction of the mmW AP. The mobile wireless communication may do so during a process of gaining access to the mmW AP.
