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.
