The donor base station provides a gateway function for the first IAB node. The first IAB node receives a first BWP configuration from the donor base station, where the first BWP configuration includes a BWP configuration of a second IAB node, and the second IAB node is a candidate upper-level node of the first IAB node. The first IAB node switches to the second IAB node. According to the IAB node switching method, the IAB node, and the donor base station that are provided in this application, service availability of an IAB node is ensured when the IAB node has a plurality of upper-level nodes.

Abstract: Data transmission methods and apparatuses for wireless backhaul networks are described. A wireless backhaul node determines one or more reporting nodes for a data volume of a first-type data packet from a plurality of next-hop nodes of the wireless backhaul node on an uplink based on the data volume of the first-type data packet, a data volume of a second-type data packet, and a data volume of a third-type data packet. The wireless backhaul node sends, to the one or more reporting nodes, a buffer status report used to indicate the data volume of the first-type data packet. At least one of the first-type data packet, the second-type data packet, and the third-type data packet includes a data packet from an adaptation layer entity of the wireless backhaul node and/or a data packet from a radio link control layer entity of the wireless backhaul node.
