Abstract: An integrated access and backhaul (IAB) node may transition between use of a mobile termination (MT) function at the wireless device and use of a distributed unit (DU) function. The IAB node may schedule communication using the DU function of the wireless device based on whether one or more guard symbols are provided for an allocation from a parent node for the MT function.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer storage media, for performing separate channel sensing procedures for transmissions via a mobile termination (MT) role and for transmissions via a distributed unit (DU) role of an integrated access and backhaul (IAB) node. In one aspect, the IAB node may obtain channel access for transmissions via the MT role by performing a first channel sensing procedure and may obtain channel access for transmissions via the DU role by performing a second channel sensing procedure. The IAB node may determine a first timing of a first sensing slot for performing the first channel sensing procedure and a second timing of a second sensing slot for performing the second channel sensing procedure in accordance with a capability of the IAB node and a transmission timing of the transmissions via the MT role and the DU role.

Abstract: Aspects relate to technologies and techniques for migrating a radio access network (RAN) node associated with a first donor node in a communications network. The first donor node may receive, via a first communications interface, such as an F1-C or resource control (RRC) interface, cell configuration data associated with one or more cells of the RAN node activated by the first donor node. The first donor node may process the cell configuration data and transit the cell configuration data, using a second communications interface, such as an Xn or X2 interface, to a second donor node for use in migrating the RAN node from the first donor node to the second donor node.

Abstract: Techniques for using simultaneous connectivity for mobility of integrated access and backhaul nodes may include an IAB node establishing a first connection with a first parent node (e.g., second IAB node) associated with a first IAB donor device (e.g., first base station) and establishing a second connection with a second parent node (third IAB node), wherein the second connection is simultaneous with the first connection. The IAB node may also switch the first connection from the first parent node to the second parent node. In doing so, the IAB node may have dual connectivity with the second parent node, where one connection is a master connection and the other connection is a secondary connection.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a node in a wireless network may transmit an indication of a capability of the node for simultaneous communication with respect to at least one of: multiple parent nodes of the node, multiple mobile termination components of the node, multiple transmit receive points of the node, multiple cells of the node, or a combination thereof; and communicate with another node in the wireless network based at least in part on the capability. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. For example, a first wireless node (e.g., an integrated access and backhaul (IAB) node) may receive, from a parent base station, system information that is indicative of two random access procedure configurations. The first random access procedure configuration may be for a two-step random access procedure and the second random access procedure configuration may be different from the first random access procedure configuration (for example, an IAB-specific, a user equipment (UE)-specific, or a four-step random access procedure). The first wireless node may determine to use the first random access procedure configuration (e.g., for establishing a wireless backhaul connection with the parent base station) and may perform the two-step random access procedure with the parent base station accordingly.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may transmit, to first central unit (CU) that corresponds to an integrated access and backhaul (IAB) donor, an indication of a first resource configuration for communications corresponding to a cell served by the network node and associated with a second CU that corresponds to a base station. The network node may receive, from the first CU, a second resource configuration comprising a distributed unit (DU) cell resource configuration for the cell. Numerous other aspects are described.

Abstract: Aspects described herein relate to quasi co-location (QCL) indications in an integrated access and backhaul (IAB) system. In an example, an IAB node may determine a spatial relation between a first communication of a DU entity and a second communication of one of the DU entity or a co-located MT entity. The IAB node may further configure a beam of at least one of the MT or the DU based on the determined spatial relation. The IAB node may further communicate using the beam with at least one entity.

Abstract: An integrated access and backhaul (IAB) node may receive a parent knowledge message, the parent knowledge message indicating whether a parent IAB node of the child IAB node has received an optional signaling message, determining to transition between first resources and second resources at a transition time, the first resources being associated with use of a mobile termination of the child IAB node, the second resources being associated with use of the distributed unit of the child IAB node, and determine a number of guard symbols provided by the parent IAB node at the transition time based on whether the parent knowledge message indicates that the parent IAB node has received the optional signaling message.

Abstract: A first control node may communicate with a user equipment (UE) using an integrated access and backhaul (IAB) network, and a second control node may manage a configuration of the IAB network. The second control node may not have the information needed to configure the IAB network, such as quality of service (QoS) information associated with a data radio bearer (DRB) used for communications between the first control node and the UE, and thus may not be able to configure a user plane interface tunnel and/or a radio link control (RLC) channel to assist with satisfying the QoS level. Some techniques and apparatuses described herein enable the second control node to receive QoS information associated with setting up a user plane interface tunnel between the first control node and an IAB node that serves a UE for which the user plane interface tunnel is being set up.
