1. A data transmission method, implemented by a base station and comprising:
transmitting a control instruction to a terminal, the control instruction carrying indication information and the indication information indicating multiple resource positions configured for the terminal to transmit feedback data in an unlicensed channel; and
receiving feedback data from the terminal, the feedback data being transmitted by the terminal through at least one resource position among the multiple resource positions in a case of the unlicensed channel being occupied by the terminal, and the feedback data indicating whether the terminal has correctly received communication data from the base station or not,
wherein
the indication information is an index identifier; and
the method further comprises:
transmitting an index table to the terminal, the index table comprising multiple resource positions corresponding to each index identifier and the index table being configured to query corresponding multiple resource positions based on any index identifier.
