Abstract: A wireless backhaul method, including: a wireless backhaul device generates a first F1AP message, maps the first F1AP message to a signaling-plane bearer of an LTE Uu interface, and sends the first F1AP message to a primary base station of the wireless backhaul device via the signaling-plane bearer of the LTE Uu interface. The primary base station obtains the first F1AP message via the signaling-plane bearer of the LTE Uu interface, encapsulates the first F1AP message into a first X2AP message, and sends the first X2AP message to a secondary base station of the wireless backhaul device. The secondary base station receives the first X2AP message and obtains the first F1AP message based on the first X2AP message.

Abstract: This application relates to the field of communication technologies, and provides a communication method, apparatus, and system. In the method, a source donor node receives a measurement report from an IAB node through a source parent node, and determines, based on the measurement report, to hand over the IAB node from the source parent node to a target parent node. The source donor node sends configuration information to the IAB node through the source parent node. In a process in which the IAB node is handed over from the source parent node to the target parent node, the IAB node sends uplink data to a target donor node by using the configuration information through the target parent node. The configuration information includes: a routing configuration and/or a bearer mapping configuration. The uplink data includes uplink user plane data and/or uplink control plane data.

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: This application provides a data transmission method and an apparatus. The method includes that an integrated access and backhaul (IAB) donor distributed unit receives downlink data and service attribute information of downlink data that are sent by an IAB donor centralized unit. The IAB donor distributed unit maps the downlink data to a corresponding backhaul radio link control channel (BH RLC) channel based on the service attribute information of the downlink data or based on the service attribute information of the downlink data and access IAB node address information of the downlink data, and sends the downlink data to a next-hop IAB node.
