Abstract: Methods, systems, apparatus for implementation in an integrated access and backhaul network (IAB) are described. One example method for wireless communication includes transmitting, by a first network node connected to one or more second network nodes by one or more first wireless links, a system information message on a second wireless link, the system information message indicating all public land mobile networks to which the one or more second network nodes provide connectivity.

Abstract: Methods, systems and apparatus for implementing multicast broadcast services in a wireless network are described. One example method includes communicating a message on an interface between a control plane (CP) function of a network node and a user plane (UP) function of the network node that provides data connectivity to one or more wireless devices in a wireless network, and configuring, based on the message, the network node to provide a service carrying a multicast or broadcast data for a session for the one or more wireless devices.

Abstract: This disclosure relates to methods and devices for routing and bearer mapping configuration in an integrated access and backhaul (IAB) network. In one implementation, the method may include detecting, by an IAB entity, a failure in transmitting a packet via an egress link of an original routing path. The method may further include selecting, by the IAB entity, a backhaul adaption protocol routing identifier of a backup routing path for the packet. The method may further include selecting, by the IAB entity, an egress backhaul radio link control channel on an egress link of the backup routing path for transmitting the packet.

Abstract: Methods, systems, and devices for latency management in integrated access and backhaul (IAB) networks for mobile communications are described. An example method for wireless communication includes receiving, by a first network node from a second network node, a measurement configuration, performing, based on the measurement configuration, one or more latency measurements, and transmitting, to the second network node, a measurement report comprising the one or more latency measurements or an identification of the channel used for the one or more latency measurements.

Abstract: Methods, systems, and devices for inter-donor topology adaptation in integrated access and backhaul (IAB) networks are described. An example method for wireless communication includes transmitting, by a source donor, a first message comprising an indication that a migrating IAB node is configured to perform an inter-donor switching operation, and receiving a second message comprising feedback information, wherein the source donor is communicatively coupled to the migrating IAB node and a plurality of nodes that are downstream from the migrating IAB node.
