  • Publication number: 20220015093
    Abstract: An apparatus of an Integrated Access and Backhaul (IAB) node includes processing circuitry coupled to a memory. To configure the IAB node for resource allocation within an IAB network, the processing circuitry is to decode radio resource control (RRC) signaling from a central unit (CU) function of an IAB donor node. The RRC signaling configures first time-domain resources for a parent backhaul link between a mobile termination (M) function of the IAB node and a distributed unit (DU) function of a parent IAB node, and second time-domain resources for a child backhaul link between a DU function of the IAB node and a MT function of a child IAB node. Uplink data is encoded for transmission to the parent IAB node based on the first time-domain resources. Downlink data is encoded for transmission to the child IAB node based on the second time-domain resources.

  • Publication number: 20210400660
    Abstract: An apparatus of an Integrated Access and Backhaul (IAB) node includes processing circuitry coupled to a memory. To configure the IAB node for time-domain resource management within an IAB network, the processing circuitry is to detect that a time-domain resource assigned to a child communication link of the IAB node is available. An uplink message is encoded for transmission by a mobile terminal (MT) function of the IAB node to a parent IAB node. The uplink message indicates availability of the time-domain resource for a parent backhaul link between the IAB node and the parent IAB node. A downlink message from the parent IAB node is decoded. The downlink message is received via the parent backhaul link and using the time-domain resource.

  • Publication number: 20210360534
    Abstract: To configure an IAB node for DL power control, the processing circuitry of the node is to decode at a DU function of the IAB node, an UL reference signal received via a communication channel from an MT function of a second IAB node. A path loss associated with the communication channel is determined, based on at least one measurement of the UL reference signal. DL transmission power is determined using the path loss. Data is encoded for a transmission to the MT function of the second IAB node using the DL transmission power, the transmission further using a DL BWP associated with the channel.

  • Publication number: 20210360550
    Abstract: An apparatus of an Integrated Access and Backhaul (IAB) node includes processing circuitry coupled to a memory. To configure the LAB node for inter-IAB node discovery and measurements within an IAB network, the processing circuitry is to encode a first synchronization signal block (SSB-A) for transmission to an access UE using a first frequency resource from a synchronization raster set of frequency resources. A second SSB (SSB-B) is encoded for transmission to a second IAB node using a second frequency resource from an off-raster set of frequency resources. The off-raster set is non-overlapping with the synchronization raster set of frequency resources and the SSB-B being time-division multiplexed with the SSB-A. A measurement report from the second IAB node is decoded. The measurement report is based on the SSB-B and associated with a backhaul link between the IAB node and the second IAB node.

  • Publication number: 20210345279
    Abstract: Embodiments of an integrated access and backhaul (IAB) node, a User Equipment (UE), and methods of communication are generally described herein. An IAB node may operate as a relay between an IAB donor and a UE. The IAB node may receive, from the IAB donor, first signaling that indicates a first timing advance (TA) offset between the IAB donor and the IAB node. The IAB node may determine a second TA offset between the IAB node and the UE. The second TA offset may be based on a timing difference between a transmission time of a downlink frame transmitted to the UE and a reception time of an uplink frame from the UE. The IAB node may transmit, to the UE, second signaling that indicates the first TA offset and the second TA offset.

    Abstract: To configure an IAB node for DU function and MT function resource transition within an IAB network, the processing circuitry is to decode configuration signaling from a DU function of an IAB parent node, which provides allocated resources for a parent backhaul link. A resource transition is detected in adjacent slots between transmission or reception of data on the parent backhaul link and a child link. A number of desired guard symbols is determined for insertion during the transmission or reception of the data to avoid overlapping of the allocated resources for the parent backhaul link and allocated resources for the DU function during the resource transition in the adjacent slots.

  • Publication number: 20210051768
    Abstract: To configure an IAB node for multiplexing communications within an IAB network, processing circuitry is to encode configuration signaling for transmission to a CU function of an IAB donor node. The configuration signaling indicates a multiplexing capability of the IAB node. RRC signaling from the CU function of the IAB donor node is decoded. The RRC signaling configures scheduling resources for a parent backhaul link between the MT function of the IAB node and a DU function of a parent IAB node based on the multiplexing capability of the MT and DU functions of the IAB node. Uplink data is encoded for transmission to the parent IAB node by the MT function using to the scheduling resources for the parent backhaul link. Transmission of the uplink data is multiplexed with transmission or reception of data by the DU function of the IAB node based on the multiplexing capability.

  • Patent number: 10825965
    Abstract: A two-stage singulation process is used in the fabrication of phosphor coated light emitting elements. Prior to the application of the phosphor coating, the individual light emitting elements are singulated using a laser dicing process; after application of the phosphor coating, the phosphor coated light emitting elements are singulated using a mechanical dicing process. Before laser dicing of the light emitting elements, the wafer is positioned on a piece of dicing- or die-attach-tape held by a frame; after laser dicing, the tape is stretched to provide space between the individual light emitting elements that allows for the wider kerf width of the subsequent mechanical dicing after application of the phosphor coating.
