Abstract: The systems and methods described herein support efficient SDM operation in IAB networks. A first node receives a semi-static resource allocation from a CU based on at least one multiplexing capability of the first node. The first node also receives from the CU one or more resource conditions for using allocated resources of the semi-static resource allocation, and the first node communicates with a second node based on the semi-static resource allocation and the one or more resource conditions. The at least one multiplexing capability includes at least one of SDM or FDM, including full duplex or half duplex. The at least one multiplexing capability is also with respect to one or more transmission direction combinations of the first node.

Abstract: A configuration for local coordination between the child node and parent node to enable SDM communication between the parent and child node, without input or interaction from the CU. The apparatus receives, from a CU, an indication including an allocation of resources. The apparatus determines a type of communication with a second node based on the allocation of resources. The apparatus communicates with the second node based on the determined type of communication and utilizing the allocated resources. The apparatus coordinates with a parent node to utilize the allocated resources in a SDM operation between the child node and the parent node.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless node may determine a default periodicity for repetition of a reference signal period, and may monitor for one or more reference signals in the reference signal period using a plurality of configurations for a plurality of intervals of the reference signal period. Each interval may be shorter than the default periodicity. Numerous other aspects are provided.

Abstract: An integrated access and backhaul (IAB) node may establish a first connection with a first base station, establish a second connection with a second base station, and receive an indication, from the first base station or the second base station, that indicates at least one of the first base station or the second base station is to serve as an IAB donor for the IAB node. The first base station may indicate to the second base station, based on the second connection being established with the IAB node, that at least one of a first base station or the second base station is to serve as an IAB donor for the IAB node.

Abstract: A method of wireless communication by an integrated access and backhaul network (IAB) donor transmits a configuration message on a source path to a first IAB node via a first distributed unit of the IAB donor. The method also instructs the first IAB node to delay delivery of the configuration message to a second node. The method migrates at least part of communications to the first IAB node from the source path to a target path via a second distributed unit. Another method of wireless communication is executed by a first integrated access and backhaul network (IAB) node. The method receives a first configuration message over a source path to a first IAB donor via a first distributed unit of the first IAB donor. The method also delays delivery of the first configuration message to a second node until a trigger occurs.

Abstract: Method and apparatus to rewrite BAP headers in IAB networks. The apparatus receives, from a second base station, a routing configuration indicating a mapping between a first routing ID and a second routing ID. The apparatus receives a packet with a packet header indicating the first routing ID. The apparatus determines the second routing ID based on the routing configuration mapping the first routing ID in the packet header to the second routing ID. The apparatus modifies, based on a determination of the second routing ID, the packet header to replace the first routing ID with the second routing ID. The apparatus transmits the packet based on the second routing ID.

Abstract: Aspects of the present disclosure provide techniques for interference measurements based on synchronization signal blocks (SSB) in a network (e.g., an Integrated Access and Backhaul (IAB) network. In some cases, a node determines resources used for periodic SSB transmissions by at least one parent node of the network, uses the determined resources to perform SSB-based interference measurements, and communicates with at least one of the parent node, a central unit (CU), or another node of the network based on the SSB-based interference measurements.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first node of a wireless network may transmit, by a first distributed unit (DU) of the first node to a central unit (CU), a second DU of another node in the wireless network, a user equipment in the wireless network, or a child node of the first node, an indication of a suggested resource pattern for the DU. The first node may transmit or receive a communication in the wireless network based at least in part on a resource pattern that is received in connection with transmitting the indication. Numerous other aspects are described.
