  • Publication number: 20210219370
    Abstract: Techniques discussed herein can facilitate reduced frequency of triggering a RLF (Radio Link Failure) timer and/or a false RLF procedure via employing one or more mechanisms for associating BFR (Beam Failure Recovery) and RLF. A first mechanism that can be employed in various embodiments can perform one or more RLF-related actions (e.g., stopping a T310 timer, resetting a N310 counter) upon BFR success. A second mechanism that can be employed in various embodiments can comprise revising one or more RLF parameters (e.g., N310, N311, T310, Out-of-sync threshold, in-sync threshold, etc.) based on the presence of a strong BFR mechanism.

  • Publication number: 20210144705
    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: 20210058926
    Abstract: To configure an IAB node for DU function and MT function resource transitions within an IAB network, the processing circuitry is to detect using allocated resources, a plurality of resource transitions in adjacent slots between transmission or reception of data on a parent backhaul link. The processing circuitry determines based on sub-carrier spacing (SCS) associated with the allocated resources, a guard symbol table with a number of desired guard symbols for each of the plurality of resource transitions. The number of desired guard symbols are for insertion during the transmission or reception of the data on the parent backhaul link to avoid overlapping of the allocated resources for the parent backhaul link and allocated resources for the DU function during the plurality of resource transitions.

  • 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.

  • Publication number: 20200374735
    Abstract: Embodiments herein provide mechanisms for configuring an integrated access and backhaul (IAB) mobile termination (MT) with one or more SMTCs. In embodiments the IAB MT may receive a radio resource control (RRC) information element (IE) with configuration information for one or more synchronization signal/physical broadcast channel (PBCH) block (SSB) measurement time configurations (SMTCs). For example, in some embodiments, the RRC IE may include configuration information for multiple SMTCs (e.g., 4 SMTCs). The IAB MT may perform one or more measurements on the multiple SMTCs and/or a selected one of the SMTCs. Other embodiments may be described and claimed.

  • 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.
