Document Type and Number:
Japanese Patent JP6545259
Kind Code:
B2
Abstract:
The present invention provides a terminal device positioning method and system, and an apparatus. A base station includes: a receiving module, configured to: receive at least one second signal, or receive a first signal and at least one second signal, where the first signal is sent by a terminal device to an antenna terminal, and the at least one second signal is generated after each antenna terminal in at least one antenna terminal performs delay processing or frequency conversion processing on the first signal; and a processing module, configured to obtain location information of the terminal device by means of calculation according to the at least one second signal or according to the first signal and the at least one second signal. Delay processing or frequency conversion processing is performed on the first signal of the terminal device, and calculation is performed according to delays and frequency offsets of multiple different second signals obtained by processing the first signal, so as to obtain a specific location of the terminal device. Therefore, terminal device positioning accuracy is effectively improved.
