Abstract: This application provides a communication method and apparatus. The method includes: A first node receives a beam set and first indication information from a second node, where the beam set includes at least one beam. The first node determines, based on the first indication information, identification information of at least one beam that needs to be forwarded by the first node in the beam set. The first node forwards, based on the identification information of the at least one beam that needs to be forwarded by the first node in the beam set and receiving time information of the at least one beam that needs to be forwarded by the first node, the at least one beam that needs to be forwarded by the first node. The method is applied to a smart repeater, to implement smart beam forwarding by the repeater.

Abstract: Embodiments of this application disclose a communication method and apparatus, to improve stability and reliability of data transmission in an integrated access and backhaul (IAB) network. A first node is served by a first master cell group (MCG) and a first secondary cell group (SCG), and a child node of the first node is a second node. The method includes: The first node sends RLF indication information to the second node when the first SCG is for transmitting an F1 interface user plane service, no radio link failure (RLF) occurs in the first MCG, and an RLF occurs in the first SCG.

Abstract: Embodiments of this application provide a communication method and apparatus. The method includes: A first node generates node configuration information and sends the node configuration information to a second node, where the node configuration information is used for conversion of a first beam set sent by the first node into a second beam set sent by the second node. This method is applied to a smart repeater for smart beam forwarding.

Abstract: This application provides an IAB network includes a first BAP topology and a second BAP topology, the first BAP topology is managed by a first donor node, the second BAP topology is managed by a second donor node. In the IAB network, a first IAB node receives a first data packet, where the first IAB node is managed by the first donor node, at least one parent node of the first LAB node is managed by the second donor node, and the first IAB node belongs to the first BAP topology. The first IAB node processes the first data packet based on a BAP topology corresponding to an ingress link for receiving the first data packet.
