| Zusammenfassung: | The invention relates to the field of mobile communications, in particular to a method for locating a mobile terminal by utilizing beam characteristics. In the method, the phased array antenna of thebase station periodically transmits beams to different directions. When the mobile terminal needs to carry out positioning, the mobile terminal searches for and receives the beams of the phased arrayantenna and carries out positioning according to the beams. Specifically, the base station calculates the actual measurement path loss between the mobile terminal and the phased array antenna. The base station calculates the distance between the mobile terminal and the phased array antenna according to the actual measured path loss; The base station calculates the position information of the mobile terminal relative to the phased array antenna according to the actual measurement of the path loss and the distance between the mobile terminal and the phased array antenna. The invention only needsone antenna array to reali |
