Provided are a positioning method, apparatus and system for a terminal device. The base station comprises: a receiving module for receiving at least one second signal, or receiving a first signal and at least one second signal, wherein the first signal is sent by a terminal device to an antenna terminal, and the at least one second signal is generated when each antenna terminal from at least one antenna terminal performs time delay processing or frequency conversion processing on the first signal; and a processing module for calculating and acquiring, according to the at least one second signal, or according to the first signal and the at least one second signal, position information about the terminal device. By performing delay or frequency conversion processing on the first signal of the terminal device, and performing calculation according to delays and frequency offsets of multiple different second signals acquired after the processing of the first signal to acquire the specific position of the terminal device, the positioning accuracy of the terminal device is effectively improved. |
