1. A data packet transmission method, comprising:
determining, by an integrated access and backhaul (IAB) donor, configuration information indicating a backhaul link (BH) radio link control (RLC) channel for transmitting a corresponding packet, and the corresponding packet is a control protocol data unit (PDU) at a backhaul adaptation protocol (BAP) layer or comprise a data payload other than an F1 user plane (F1-U) data payload and an F1 control plane (F1-C data payload; and
sending, by the IAB donor, the configuration information to an IAB node,
wherein the configuration information comprises a channel identifier of the BH RLC channel for transmitting the corresponding packet; or
the configuration information comprises a logical channel identifier, and a logical channel indicated by the logical channel identifier corresponds to the BH RLC channel for transmitting the corresponding packet.
