    Abstract: Technology for an integrated access and backhaul (IAB) donor operable to communicate synchronization signal block (SSB) transmission coordination information is disclosed. The IAB donor in a Fifth Generation New Radio (5G-NR) IAB network can determine SSB transmission coordination information for the IAB donor and a plurality of IAB nodes. The IAB donor can encode the SSB transmission coordination information for transmission from a central unit (CU) of the IAB donor to a distributed unit (DU) of an IAB node in the plurality of IAB nodes. The SSB transmission coordination information can enable the plurality of IAB nodes to send and receive SSBs to one or more of the IAB donor or other IAB nodes of the plurality of IAB nodes in the 5G-NR IAB network in accordance with a half-duplex constraint.

    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.

    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.

    Abstract: Embodiments of a system and method for dual connectivity for device to vehicle or vehicle to vehicle communication in a Wireless Network are generally described herein. In some embodiments, processing circuitry may determine a quality of service (QoS) level for data to be transmitted over a first radio access technology (RAT) connection and determine a QoS indicator from the QoS level, the QoS indicator identifying a dual connectivity backup transmission, the dual connectivity backup transmission including a hot, warm, or cold backup. In some embodiments, transceiver circuitry may attempt to transmit the data using a first transmission mode, the first transmission mode using the first RAT connection and the data including the QoS indicator and retransmit, in response to the attempt failing, the data using a second transmission mode.

    Abstract: An apparatus and system are described to provide functions and procedures in a data-centric infrastructure (DCI). The logical architecture includes an infrastructure orchestration function and controller. Interactions between the infrastructure orchestration function and controller include a function request to form or release a logical computing node, or modify the logical computing node through addition or removal of at least one of a function-dedicated computing (FDC) function, a data plane (DP) function, or a function-dedicated network (FDN) function to the logical computing node. The controller configures the FDC/DP/FDN functions and sends a response indicating completion of operations performed by the controller that are related to the function request.

    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.
