Abstract: An integrated access and backhaul (IAB) node configuration method includes receiving, by a target IAB donor, first information from a source IAB donor. The method also includes sending, by the target IAB donor, first configuration information to the source IAB donor. The first configuration information is for handing over an IAB node from the source IAB donor to the target IAB donor. The IAB node includes a mobile terminal (MT) function and a distributed unit (DU) function. The first configuration information is based on the first information. The first configuration information indicates a transmission direction of a time domain resource configured by the target IAB donor for the MT function. The first information indicates one or more different types of information.

Abstract: A communication apparatus includes a processor coupled to a memory. The memory is configured to store non-transitory instructions. The processor is configured to execute the non-transitory instructions to thereby cause the communication apparatus to perform operations including sending first information to a target integrated access and backhaul (IAB) donor of an IAB node, and receiving second information from the target IAB donor. The first information includes request information useable for setting up a first F1 interface. The second information includes feedback information of the request information. The first F1 interface is a communication interface between a distributed unit (DU) of the IAB node and a central unit (CU) of the target IAB donor. The communication apparatus is a source IAB donor of the IAB node or included in a IAB donor.

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 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.
