Abstract: The present disclosure relates to methods applied to an integrated access and backhaul (IAB) node. An example method includes receiving configuration information for setup of a distributed unit (DU) part of the IAB node and determining, based on a manner of receiving the configuration information, that a master node of the IAB node or a secondary node of the IAB node is a donor node of the IAB node.

Abstract: A method includes: a first IAB node sets up a first RRC connection to a target IAB donor by performing RLF recovery. The first IAB node sends a first message to a second node by using an SRB 1 or an SRB 2 or the first IAB node sends a BH RLF indication to the second node. t The first IAB node sets up an RRC connection to a target IAB donor by performing RLF recovery and the second node is connected to a source IAB donor through the first IAB node. The second node may be triggered to set up an second RRC connection to the target IAB donor based on the first message or the BH RLF indication.

Abstract: A method for releasing an F1 connection is used for an IAB node. The method includes: receiving a first message from a source IAB donor node, where the first message indicates that a central unit CU of an IAB donor node connected to the IAB node changes; and releasing an F1 connection to a CU of the source IAB donor node according to the first message. Therefore, the IAB node can release the F1 connection in time based on an indication of the source IAB donor.

Abstract: Embodiments of this application provide communication method and related devices. In an example method, a first IAB-donor-central unit (CU) determines a quality of service (QoS) attribute corresponding to an F1 application protocol (F1AP) message, where an F1 interface is a communication interface between the first IAB-donor-CU and a distributed unit (DU) of an IAB-node. Then, the first IAB-donor-CU sends the F1AP message and the QoS attribute corresponding to the F1AP message to a second IAB-donor-DU.

Abstract: A communication method and a related device include in response to a first node determining that an RLF occurs on a radio link between the first node and a second node, and there is no other available path between the first node and a destination node, the first node sends first indication information to a third node. The first indication information indicates the RLF or indicates that a link recovery attempt is being made. The second node is a parent node of the first node, and the third node is a child node of the first node; or the second node is a child node of the first node, and the third node is a parent node of the first node, or a donor node connected to the first node.

Abstract: A data transmission method and apparatus. The method is applied to a first integrated access and backhaul (IAB) donor, and includes: receiving a first message from a core network element, where the first message carries an identifier of a first protocol data unit (PDU) session and a first data network name (DNN) associated with the identifier of the first PDU session, and the first DNN indicates a local data network corresponding to a first IAB node; the first IAB node includes a first IAB central unit-user plane (CU-UP), a first IAB-distributed unit (DU), and a first IAB-mobile terminal (MT); and the first IAB CU-UP is connected to the local data network; and notifying the first IAB CU-UP to establish the first PDU session.

Abstract: Embodiments of this disclosure provide a communication method, and an associated communication apparatus, medium, and chip. In a communication method, a target access network device receives first information, where the first information indicates a relationship between a first network slice in a first network and a second network slice in a second network, and the first network is different from the second network. The target access network device performs access control from a terminal device to the target access network device based on at least the first information. In this manner, in embodiments of this disclosure, the target access network device can perform access control on the terminal device during cross-network access, to reduce an access latency, reduce a service interruption problem caused by session rejection of the terminal device, and ensure service continuity of the terminal device.
