  • Publication number: 20200228261
    Abstract: A method for a base station can create a subframe structure used in communication between the base station and a UE. The subframe structure can include a plurality of subframes each having a subframe duration. The method can include operating a serving cell on a carrier frequency. The method can include performing a LBT on the carrier frequency for a time duration that at least partially overlaps a terminal portion of a subframe duration of a first subframe of the plurality of subframes. The method can include determining a position of a starting OFDM symbol for transmitting a control channel in a second subframe of the plurality of subframes based on the time duration of the LBT. The subframe duration of the second subframe can occur immediately after the subframe duration of the first subframe.

  • Patent number: 10693610
    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.

  • Patent number: 10581566
    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.

  • Patent number: 10542464
    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.

  • 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.
