  • Patent number: 10420101
    Abstract: Aspects of traffic aware slot assignment are described, for example, in a multi-hop wireless network comprising a plurality of nodes. In some aspects, an apparatus of a wireless device is configured to decode signaling, received from a node of the multi-hop network, to determine an indication of a change to a topology of the multi-hop network. The apparatus is further configured to, in response to a determination, from the decoded signaling, of an addition of a second node to the multi-hop network topology, increment a total of a number of descendant nodes, and allocate one or more transmission slots to a number of unused slots in one or more transmission opportunity regions of a slotframe, wherein the slotframe includes a repeating pattern of one or more transmission opportunity periods for a plurality of nodes in the network.

  • Publication number: 20190174344
    Abstract: Systems and methods of providing V2X communications are generally described. The multimode UE communicates V2X messages with an eNB. The eNB detects whether the UE is able to receive messages from a nearby DSRC RSU based on measurements received from the UE and reported to the eNB. Based on the measurements, the eNB offloads V2X traffic to the DSRC RSU and triggers the UE to start communicating the V2X services from the DSRC RSU rather than the eNB. The measurements are reported in a BSR or DSRC MAC control element or RRC measurement report. The measurement report includes DSRC presence fields, CCH measurements and SCH measurements for each DSRC RSU that the UE is able to detect.

  • Publication number: 20190150082
    Abstract: Systems and methods of providing a V2X communications are generally described. A geographically-limited, operator-independent mapping table is used that maps between groups of V2X applications each associated with a different application category and a different RAT preferred for the V2X application category. Each grouping is based on fulfillment of one or more KPIs for the associated V2X application category. Multiple RATs are prioritized if able to fulfill the KPIs. The mapping table is modified based on the RATs supported by the V2X UE. Carrier aggregation is used when simultaneous transmission on different RATs is desired.

  • Publication number: 20180184450
    Abstract: A wireless communication station, method, and related computer program product are provided for communicating over a wireless communication medium. The station comprises an allocation unit configured to allocate a dedicated time-sensitive network (TSN) contention-based-access-period (CBAP) to a first pair of stations (STAs) to allow a synchronous TSN traffic flow between the first pair of STAs. The allocation unit allocates a shared TSN CBAP to a second pair of STAs to allow an asynchronous TSN traffic flow between the second pair of STAs using contention-based rules. The allocation unit allocates a shared non-TSN CBAP to a third pair of STAs to allow a non-TSN traffic flow between the third pair of STAs. The station further transmits over the wireless communication medium, a scheduling element to schedule a dedicated TSN CBAP, a scheduling element to schedule a shared TSN CBAP, and a scheduling element to schedule a shared non-TSN CBAP.
