Abstract: Embodiments of an integrated access and backhaul (IAB) donor, IAB node, and methods of communication are generally described herein. An IAB network may comprise a plurality of IAB nodes to operate as relays between the IAB donor and one or more User Equipment (UE). The IAB donor may, for each of the IAB nodes, allocate a plurality of subframes to the IAB node. Each allocated subframe may have a subframe type that is one of: a downlink subframe, an uplink subframe, a flexible subframe or a not available subframe. The IAB donor may transmit, from a central unit (CU) of the IAB donor to a distributed unit (DU) an IAB node over an F1 interface, a resource coordination request message that indicates the subframe types of the plurality of subframes.

Abstract: Embodiments of a Next Generation Node-B (gNB) and methods of communication are disclosed herein. The gNB may be configured with a gNB central unit (gNB-CU) and a gNB distributed unit (gNB-DU). The gNB-CU may determine a route for delivery of a data packet to a User Equipment (UE) on an integrated access backhaul (IAB) of relays. The gNB may generate a physical layer (PHY) data packet in accordance with a split between functionality of a packet data convergence protocol (PDCP) layer at the gNB-CU and functionality of a radio link control (RLC) layer at the gNB-DU. The PHY data packet may include the data packet, a PDCP header, an adaptation layer header, an RLC header, a medium access control (MAC) header, and a PHY header. The adaptation layer header may indicate one or more relays included in the route.

Abstract: Systems, methods, and circuitries are provided for communicating DU resource configuration information of a child IAB node to a parent IAB node. An example method includes identifying distributed unit (DU) resource configuration information for an IAB node device functioning as an IAB node in the IAB network, wherein the IAB node is associated with a parent IAB node, and transmitting the DU resource configuration information to the parent IAB node.

Abstract: Some embodiments of this disclosure include apparatuses and methods for providing semi-static integrated access backhaul (IAB) resource configurations in an IAB network. For instance, a central unit (CU) of an IAB donor can provide, to a distributed unit (DU) of an IAB node, F1 application protocol (F1AP) signaling data indicative of a semi-static IAB resource configuration regarding at least one of downlink resources, uplink resources, or flexible resources. The semi-static IAB resource configuration indicates whether the at least one of downlink resources, uplink resources, or flexible resources are hard resources, soft resources, or not available resources. The CU can further provide, to a mobile termination (MT) of the IAB node, radio resource control (RRC) signaling data indicative of the semi-static IAB resource configuration.

Abstract: A device of a New Radio (NR) evolved Node B (gNodeB), a method and a machine readable medium to implement the method. The method includes: processing a first signal sent by a NR evolved NodeB (gNodeB) regarding a primary physical random access channel (PRACH) configuration to be used to encode for transmission a first communication to the gNodeB; processing a second signal sent by the gNodeB regarding a secondary PRACH configuration different from the primary PRACH configuration and to be used to encode for transmission a second communication to the gNodeB; determining the primary PRACH configuration from the first signal and the secondary PRACH from the second signal; and switching from the primary PRACH configuration to the secondary PRACH configuration and encode for transmission the second communication to the gNodeB based on the secondary PRACH configuration.

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.
