Abstract: Embodiments of the present invention describe a data transmission method, a related device, and a system. The method may include sending, by a terminal, uplink data to a network device. The uplink data is scrambled by using a scrambling sequence, and the scrambling sequence is generated based on information about a radio resource used by the terminal to send the uplink data. According to the embodiments of the present invention, it can be ensured that scrambling and descrambling on the uplink data are successfully implemented when the network device does not obtain an identifier of the terminal in a cell.
