  • Patent number: 10313070
    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.

  • Patent number: 10292198
    Abstract: A method of setting up a wireless ad hoc network includes constructing an initial network graph by a source device. The network graph represents the source device, at least one intermediate device, and at least one communication path between the source device and the intermediate device. The initial network graph is sent from the source device to the intermediate device along with an update request. The source device receives a second network graph from the intermediate device in response to sending the initial network graph, and determines an updated network graph by performing a union of the initial network graph and the second network graph. The process is performed by each intermediate device required to reach a destination device.

  • Patent number: 10270570
    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.

  • Publication number: 20190052443
    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.

  • Publication number: 20180368189
    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.

  • Patent number: 10142072
    Abstract: A UE can receive Zero Power Channel State Information Reference Signal (ZP-CSI-RS) configuration information for an aperiodic ZP-CSI-RS of a serving cell. The UE can receive Downlink Control Information (DCI) on a physical control channel in a subframe of the serving cell. The DCI can indicate whether a Physical Downlink Shared Channel (PDSCH) of the UE in the subframe of the serving cell is rate-matched around resource elements indicated by the ZP-CSI-RS configuration information. The UE can decode the PDSCH in the subframe of the serving cell based on rate-matching around the resource elements indicated by the ZP-CSI-RS configuration when the DCI indicates the PDSCH of the UE is rate-matched around the resource elements indicated by the ZP-CSI-RS configuration.
