The first configuration information indicates that when one or more respective values of one or more first fields in a data packet correspondingly meets respective first value ranges of the first fields, the data packet is transmitted through a first channel between the donor distributed unit (DU) and a child node. The first configuration information is stored. In a second example, first configuration information is obtained indicating that when one or more respective values of one or more first fields in a data packet meet one or more respective first value ranges of the one or more first fields, the data packet is transmitted through a first channel between a donor DU and a child node, and the first configuration information is sent to the donor DU.

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: Embodiments of this application provide a communication method and apparatus, and a storage medium. The communication method includes: determining a target buffer status report (BSR) format based on a result of comparison between a first identifier and a first value, where the first identifier is a largest logical channel group (LCG) identifier in LCG identifiers of LCGs having buffered data; and generating a BSR based on the target BSR format. Uplink transmission resources can be properly used to report a BSR.
