Abstract: In an integrated access backhaul (IAB) network, a third network node sends quality of service (QOS) mapping information to a first network node to configure an internet protocol (IP) header for a packet based on a traffic type and to transmit the packet. The third network node sends a mapping configuration to a second network node to map information in the IP header for the packet received in a first routing path from the first network node to a second routing path. The first network node receives the QoS mapping information and generates a packet associated with the traffic type and including an IP header, which is configured based on the received QoS mapping information. The first network node transmits the packet for routing to the second network 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: Methods, systems, and devices for wireless communications are described. A wireless repeater may communicate with multiple base stations, and the wireless repeater may identify a first base station as a primary base station. The wireless repeater may monitor for and receive control information from the primary base station, where the control information may include control information from a second base station and used by the wireless repeater to communicate with one or more UEs connected to the second base station. The primary base station may receive an indication of the control information from the second base station via a backhaul link. In other examples, the wireless repeater may monitor for control information from the two or more base stations based on a control signaling pattern. For example, the wireless repeater may be configured with periodic time intervals for monitoring for control signaling from respective base stations.

Abstract: Methods, systems, and devices for wireless communications are described. Aspects of the present disclosure provide techniques to achieve inter-base station beam management to avoid interference during full-duplex (FD) operations, half-duplex (HD) operations, flexible time-domain duplexing (TDD), or a combination thereof, by performing interference management specific to beam configurations. For example, a first base station (e.g., an aggressor base station operating in FD) may perform one or more actions to proactively determine if inter-base station interference may occur. In some cases, the aggressor base station may request measurements from one or more victim base stations. In other examples, the victim base station may request measurements from the aggressor base station. Additionally or alternatively, the victim base station may provide reactive feedback to the aggressor base station upon detecting interference.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for leveraging a resource management protocol under an integrated access and backhaul (IAB) framework for power savings. In some aspects, a first node (such as an IAB node) may receive resource management information from a second node (such as an IAB donor). The resource management information may indicate an unavailable type of resource management configuration for the first resource associated with the first node. The first node may schedule a power save mode during the first resource having the unavailable type of resource management configuration for power savings. The first resource may be a time domain resource, a frequency domain resource, or a spatial domain resource. In some aspects, the first node may restrict both non-exempt and exempt communications during the first resource when the first node is in the power save mode.

Abstract: A network device is provided with excessive interference mitigation. In one implementation, the network device transmits a notification of the excessive interference to a network entity. In another implementation, the network device changes a receive beam or begins to acquire a new cell in response to a detection of the excessive interference. In yet another implementation, the network device alerts a user in response to a detection of the excessive interference.
