摘要： This application may be applied to the field of wireless communication technologies, and provides an RLF recovery method for an IAB network. The method includes: A first IAB node sets up an RRC connection to a target IAB donor by performing RLF recovery. After that a first IAB node sets up an RRC connection to a target IAB donor by performing RLF recovery, the first IAB node sends a first message to a second node by using an SRB 1 or an SRB 2, or the first IAB node sends a BH RLF indication to the second node. Before that a first IAB node sets up an RRC connection to a target IAB donor by performing RLF recovery, the second node is connected to a source IAB donor through the first IAB node. In this application, the second node may be triggered to set up an RRC connection to the target IAB donor based on the first message or the BH RLF indication. In this way, the connection between the second node and the target IAB donor can be recovered as soon as possible, so that network connection reliability is improved.

摘要： This application provides a resource allocation method and a communications apparatus. The method includes: A first node sends, to a radio access network device, first indication information used to indicate that the first node is a node responsible for terminal device management. The radio access network device allocates a first resource to the first node based on terminal devices that the first node is responsible for managing, and sends first resource information to indicate the first resource. In other words, the first node sends, to the radio access network device, the first indication information used to indicate that the first node is the node responsible for terminal device management, so that the radio access network device allocates different first resources based on different terminal devices that the first node is responsible for managing. In this way, the first resource can be allocated to the first node more properly, so that resource utilization is improved.
