Abstract: This application provides a data transmission method and an apparatus. The method includes that an integrated access and backhaul (IAB) donor distributed unit receives downlink data and service attribute information of downlink data that are sent by an IAB donor centralized unit. The IAB donor distributed unit maps the downlink data to a corresponding backhaul radio link control channel (BH RLC) channel based on the service attribute information of the downlink data or based on the service attribute information of the downlink data and access IAB node address information of the downlink data, and sends the downlink data to a next-hop IAB node.

Abstract: The present disclosure discloses example downlink buffer status feedback methods and apparatuses. One example method includes determining first information by a first node, where the first information indicates a downlink buffer status of a first bearer between the first node and a parent node of the first node. The first information is sent by the first node to a second node, where the first node is a relay node in a wireless relay communications system, and the second node is a parent node of the first node.

Abstract: This application provides a communication method and a communications apparatus. A first entity buffers data, so that a packet loss caused by backhaul link switching or a radio link failure can be avoided as much as possible. The communication method is applied to a relay system. The relay system includes a first node, a source node, and a target node, and the source node provides a service for the first node. The method includes: determining, by the first node, to be handed over from the source node to the target node; and storing, by the first node, data buffered in at least one first entity, where the first entity is a radio link control RLC entity or an adaptation layer entity.

Abstract: An information transmission method in which a first device receives a first message that is sent by a base station, where the first message includes first indication information and system information, and the first indication information is used to determine whether to broadcast the system information; and the first device determines, according to the first indication information, that the system information needs to be broadcast, and broadcasts the system information. In this application, the first message of the base station carries the first indication information. In this way, after receiving the first message, the first device may determine to broadcast the system information according to the first indication information, so that a target device receiving the system information accesses the base station by using the system information.
