A method, a system and a device for sending a random access preamble are provided. The method includes: a base station determines an uplink component carrier to be utilized by a terminal for sending a random access preamble, and sends identification information of the uplink component carrier to the terminal (30); and the terminal selects a component carrier corresponding to the uplink component carrier identification from multiple uplink component carriers which are supported by the terminal, and sends a random access preamble to the base station utilizing the component carrier (31). With the invention, a terminal in a Long Term Evolution Advanced (LTE-A) system can select a component carrier for sending a random access preamble based on indication of a base station.
