Abstract: A communication method and a communication device. A first donor node generates a first data packet, where the first data packet further includes first information. The first information indicates a donor node to which a destination node of the first data packet belongs, or indicates a network segment to which a destination node of the first data packet belongs, or indicates whether a network segment to which a destination node of the first data packet belongs is a network segment controlled by the first donor node. The first donor node sends the first data packet to the destination node first node.

Abstract: An integrated access and backhaul (IAB) node configuration method includes receiving, by a target IAB donor, first information from a source IAB donor. The method also includes sending, by the target IAB donor, first configuration information to the source IAB donor. The first configuration information is for handing over an IAB node from the source IAB donor to the target IAB donor. The IAB node includes a mobile terminal (MT) function and a distributed unit (DU) function. The first configuration information is based on the first information. The first configuration information indicates a transmission direction of a time domain resource configured by the target IAB donor for the MT function. The first information indicates one or more different types of information.

Abstract: Embodiments of this application provide a communication method and a related device. In the method, a first terminal device receives a first radio resource control RRC message from a second terminal device, and then sends a first message to a network device through a first radio bearer configured by using obtained first configuration information. The first message includes a first RRC message that requests to set up an RRC connection between the second terminal device and the network device, and identification information of the second terminal device. In this way, communication between the second terminal device and the network device is implemented in a user equipment-to-network relay (U2N) scenario. This increases a success rate of accessing the network device by the second terminal device, enhances a coverage capability of the network device, and improves an access capacity of the network device.

Abstract: A communication apparatus includes a processor coupled to a memory. The memory is configured to store non-transitory instructions. The processor is configured to execute the non-transitory instructions to thereby cause the communication apparatus to perform operations including sending first information to a target integrated access and backhaul (IAB) donor of an IAB node, and receiving second information from the target IAB donor. The first information includes request information useable for setting up a first F1 interface. The second information includes feedback information of the request information. The first F1 interface is a communication interface between a distributed unit (DU) of the IAB node and a central unit (CU) of the target IAB donor. The communication apparatus is a source IAB donor of the IAB node or included in a IAB donor.

Abstract: A communication method and apparatus are provided. The method includes: An IAB donor gNodeB determines first indication information, and then sends a first message to an eNB, where the first message includes a first control plane message and the first indication message; and the eNB may determine a first radio bearer based on the first indication information in the received first message, and then sends a second message including the first control plane message to an IAB node by using the first radio bearer. The first radio bearer corresponds to a type of a downlink F1AP message, so that the eNB selects different radio bearers for different types of downlink F1AP messages, thereby providing an effective QoS guarantee for a service of a terminal.

Abstract: A data packet transmission method and apparatus are provided. The method includes: An IAB donor determines first configuration information, where the first configuration information is used to indicate a first backhaul link BH RLC channel, and the first BH RLC channel is used to transmit a control protocol data unit PDU at a backhaul adaptation protocol BAP layer. The IAB donor sends the first configuration information to an IAB node. According to the foregoing procedure, the IAB donor indicates, by using the first configuration information, the IAB node to send the control PDU at the BAP layer through the first BH RLC channel, to implement bearer mapping when the IAB node needs to send the control PDU at the BAP layer.

Abstract: A communication method is provided. A first node which is a CU in a first IAB donor node, receives a first message from a second node which is a CU in a second IAB donor node, where the first message indicates to reconfigure a resource that is in a first topology and that is used to serve first traffic, the first topology is a topology controlled by a first node, and the first traffic is traffic of a third node or traffic of a downstream node of the third node; and reconfigures, based on the first message, the resource that is in the first topology and that is used to serve the first traffic. There is an RRC connection between the third node and each of the first node and the second node, there is an F1 connection between the third node and the second node.
