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.

Abstract: Various embodiments herein provide techniques for integrated access and backhaul (IAB) nodes that operate with simultaneous mobile terminal (MT) and distributed unit (DU) communication. For example, embodiments may include mechanisms for aligning the communications (e.g., slot-based alignment or symbol-based alignment). Additionally, embodiments may include mechanisms for guard symbol management for IAB MT/DU simultaneous operation. Other embodiments may be described and claimed.

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.
