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: Example configuration methods and apparatus are described. An example communications system includes a master node and a secondary node that jointly provide a service for a terminal. One example method includes generating configuration information for a signaling radio bearer (SRB) by the secondary node, where the SRB is used to transmit a radio resource control (RRC) message between the secondary node and the terminal. The secondary node sends the configuration information for the SRB to the master node, so that the configuration information for the SRB is sent to the terminal through the master node. The secondary node receives a result of configuring the SRB by the terminal by using the configuration information for the SRB. In this way, the SRB can be established on the secondary node, and used for RRC message transmission between the secondary node and the terminal.
