Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a relay user equipment (UE) may establish a sidelink unicast link with a remote UE via a sidelink signaling interface. The relay UE may identify configuration information for an adaptation layer of the sidelink signaling interface, the configuration information including at least one of: a remote UE identifier associated with the sidelink unicast link for a relay service, bearer identifier information identifying one or more bearers between the remote UE and a network entity for the relay service, a radio link control (RLC) channel mapping between a bearer identifier and one or more RLC channels, or data routing information associated with the relay service. The relay UE may relay communications between the remote UE and the network entity based at least in part on the configuration information. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a child node of a parent node in an integrated access backhaul (IAB) network may determine communication information that includes one or more of a schedule or a configuration for a communication to be transmitted by the child node. The child node may be an IAB node, and the parent node may be an IAB donor or an intervening IAB node between the IAB node and an IAB donor. The child node may transmit the communication information to the parent node via a wireless backhaul link between the child node and the parent node. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a child node may receive a message, from a serving or neighboring cell, that includes an indication of an intended time division duplex (TDD) configuration for the serving or neighboring cell. The indication may include downlink and uplink indicators for at least one slot used within the intended TDD configuration. Accordingly, the child node may determine a symbol to use within a TDD configuration for the child node, based at least in part on receiving the message. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described that provide for mesh connectivity between integrated access and backhaul (IAB) nodes. A first node of an IAB network may determine a routing address for a second node, and communications may be transmitted to the second node based on the routing address to allow for coordination between the first and second nodes. The first node may detect a discovery signal of a second node, and may determine to communicate with the second node based on the discovery signal. The first node may obtain the routing address based on one or more of transmitting a request for the routing address to a third node, establishing a sidelink connection with the second node to obtain the routing address, receiving a mapping between routing addresses and cell IDs that are transmitted in discovery signals, or any combinations thereof.

Abstract: In certain aspects, the disclosure is directed to a user equipment (UE) configured for wireless communications with a network node. The UE may include a memory comprising instructions, and one or more processors configured to execute the instructions. In some examples, the UE may transmit, to a network node, an indication of an expected communication. In some examples, the UE may receive, from the network node, updated scheduling in response to the indication of the expected communication. For example, the UE may predict a future sidelink/uplink communication based on whether the UE expects data for a future uplink transmission. If the UE expects that it will have data for a future uplink transmission, the UE may notify the network node so that the network node can enter into a low power state until the future transmission, then provide the UE with a sidelink/uplink grant for the future uplink transmission.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an apparatus of a central or management entity of an integrated access and backhaul (IAB) network may receive a report indicating one or more of a failure associated with a communication link associated with an IAB node included in the IAB network or a quality of service (QoS) associated with the communication link. The apparatus may modify a topography of the IAB network or routing within the IAB network when the report indicates the failure associated with the communication link. The apparatus may verify a QoS associated with the IAB network when the report indicates the QoS associated with the communication link. Numerous other aspects are described.

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 an SDM operation between the child node and the parent node.

Abstract: When an integrated access backhaul (IAB) node connected to a user equipment (UE) detects a radio link failure in a communication with an IAB donor, the IAB node may perform various features to cause the UE perform one or more features accordingly without explicitly indicating the radio link failure to the UE. The IAB node may detecting a radio link failure in a communication between the IAB node and an IAB donor, and determine whether the IAB node has recovered from the radio link failure. The IAB node may refrain from broadcasting one or more synchronization signal blocks (SSBs) to one or more UEs including a UE connected to the IAB node in response to determining that the IAB node has not recovered from the radio link failure.
