Abstract

The invention provides a method for localizing a mobile terminal. The method comprises the following steps that: a base station sends a reference signal to a mobile terminal periodically; a base station receives first parameter information sent by the mobile terminal and measures and calculates an NLOS zone in an area under administration according to the first parameter information; when entrance of the mobile terminal into the NLOS zone is detected, the base station obtains arrival time ToA of the mobile terminal and adjusts the obtained ToA and the base station measures and calculates arrival time AoA of the mobile terminal and adjusts the AoA obtained by measurement and calculation; and the base station localizes the mobile terminal according to the adjusted ToA and AoA. In addition, the invention also provides a base station using the method. According to the method and the base station using the same, location information of the mobile terminal can be calibrated, thereby improving the location precision of the mobile terminal by the base station.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular, the present invention relates to a method for locating a mobile terminal and a base station. Background technique [0002] Wireless communication systems have become a primary means of communication by which most people around the world are able to communicate. Wireless communication devices are becoming smaller and more powerful at the same time to meet consumer demands and to increase portability and convenience. [0003] Electromagnetic waves with wavelengths from 10 millimeters to 1 millimeter and frequencies from 30 gigahertz (GHz) to 300 gigahertz (GHz) are called millimeter waves. The method of communicating using millimeter waves is called millimeter wave communication. Millimeter wave communication is divided into two categories: millimeter wave waveguide communication and millimeter wave radio communication. The advantages of millimeter wave commun...
