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: Example mapping methods and apparatus are described. One example method includes determining a message type of an uplink signaling message by an integrated access and backhaul node. The integrated access and backhaul node maps the uplink signaling message to a corresponding backhaul radio link control (BH RLC) based on an uplink mapping relationship from an integrated access and backhaul donor centralized unit and the message type. The uplink signaling message is sent to a parent node of the integrated access and backhaul node.
