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.

Signaling for multicast broadcast services

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.

Inter-donor topology adaptation in integrated access and backhaul networks

A method of wireless communication is described. The method includes sending, from a first central unit (CU) configured to communicate with an integrated access and backhaul (IAB) node, to a second CU, a first message; and receiving, by the first CU, a second message that includes configuration information, wherein the first message includes at least one of an identification of the IAB node, an identification of a user device in communication with the IAB node.

Signaling exchange schemes in wireless communications

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.

Methods and devices for routing and bearer mapping configuration

Provided are an initiation method and apparatus, a reselection method and apparatus, a device, and a storage medium. The initiation method is applied to a first communication node, where the first communication node is in a connected state, an idle state or an inactive state, and includes: receiving relay function configuration information sent by a second communication node; and initiating, according to a comparison result of the relay function configuration information and a first current parameter value, a relay function corresponding to the comparison result, where the first current parameter value includes a measurement value and a traffic priority.
