Abstract: This application provides a communication method and an apparatus. UE establishes a connection to a home access gateway by using CPE, the home access gateway sends configuration information of a first link and configuration information of a second link to the CPE, and sends the configuration information of the second link to the UE. The first link is a link between the CPE and the home access gateway, the second link is a link between the CPE and the UE, the configuration information of the first link is used to indicate quality of service QoS information of the first link, and the configuration information of the second link is used to indicate QoS information of the second link. The UE and the CPE ensure, based on respective configuration information, QoS of UE service data transmitted on the first link and the second link.

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: The present disclosure relates to integrated access and backhaul (IAB) node dual connectivity setup methods and communication apparatus. In one example method, a first IAB node sets up a first F1 interface with a primary donor node of the first IAB node. The first IAB node obtains an internet protocol (IP) address anchored at a secondary donor node connected to the first IAB node and/or configuration information of a serving cell, of the first IAB node, belonging to the secondary donor node. The first IAB node sends, to the secondary donor node, a request for setting up a second F1 interface with the secondary donor node, where the request includes the configuration information of the serving cell, of the first IAB node, belonging to the secondary donor node.
