  • Patent number: 9800696
    Abstract: A method of operating a wireless ad hoc network includes configuring an intermediate device with a first linear network code corresponding to a first source device and a second linear network code corresponding to a second source device. The intermediate device is on communication paths from the first source device and the second source device to a plurality of destination devices. The intermediate device receives packet data from either the first source device or from the second source device, and determines whether to apply the first linear network code or the second linear network code to the packet data. The intermediate device generates outgoing packet data and sends the packet data to at least one destination device of the plurality of destination devices using either the first linear network code or the second linear network code.

  • Patent number: 9801223
    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.

  • Publication number: 20170302419
    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: 20170290034
    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.

  • Publication number: 20170289909
    Abstract: Disclosed are methods for delivering data (212) to a wireless station (102). An access point (104), or any other suitable device or system, receives a plurality of association requests (204) from a plurality of wireless stations (102) and transmits a different association identifier (208) to each of the plurality of wireless stations (102). The access point (104) buffers data (212) for a subset of the wireless stations (102). If the number of wireless stations (102) with buffered data (212) at the access point (104) is less than a threshold, then the access point (104) transmits a list of association identifiers indicating that buffered data (212) are held for each wireless station (102) identified by the list.

  • Publication number: 20170289864
    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: 9781712
    Abstract: A method and apparatus schedule user equipment uplink transmissions on an unlicensed carrier. A grant for transmitting physical uplink shared channel on a serving cell operating on an unlicensed carrier can be received in a subframe. A set of subframes can be determined for possible transmission of the physical uplink shared channel. Listen before talk can be performed on the unlicensed carrier to determine an earliest unoccupied subframe in the set of subframes. A physical uplink shared channel can be transmitted in multiple subframes within the set of subframes on the unlicensed carrier, starting with the earliest unoccupied subframe, in response to receiving the grant.

  • Publication number: 20170250958
    Abstract: The present invention provides a system and method for receiving and relaying a paging message via a paging proxy in a wide area wireless network. The system and method include detecting a proxy device for acting as a paging proxy near a present position of the mobile wireless communication device, where the proxy device includes a communication connection with a network paging controller, and is adapted to interact with the mobile wireless communication device separately from a wide area communication connection used by the mobile device to communicate with the wide area wireless network. The mobile wireless communication device is then associated with the proxy device for receiving and relaying an indication of paging messages on behalf of and to the mobile wireless communication device.

  • Publication number: 20170149484
    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.
