Abstract: Disclosed in the present invention are a data transmission method, a feedback information transmission method, and a related device, used for providing a solution for transmitting data on an unlicensed frequency band in an LTE system. The method comprises: a terminal device, on the basis of a signal/information sent by a network device, determines a starting time of a system wireless sub-frame; the terminal device, on the basis of a system wireless sub-frame n+1 starting time, receives downlink control information, wherein n is the serial number of the system wireless sub-frame; the terminal device, on the basis of the downlink control information, determines in the system wireless sub-frame n the starting time of a service sub-frame m, wherein m is the serial number of the service sub-frame, the starting time of the service sub-frame m being different to the starting time of the system wireless sub-frame n, and the length of the service sub-frame being different to the length of the system wireless sub-frame; and the terminal device receives service data during the service sub-frame m.
