Abstract
A method of positioning a terminal includes: receiving a first radio signal generated through beamforming from a base station; obtaining a cell ID and a beam ID from the first radio signal; obtaining a received signal intensity of the first radio signal; and estimating a first position of the terminal by comparing a fingerprint in which a cell ID, a beam ID, and a received signal intensity are mapped to each point on a map with the cell ID, the beam ID, and the received signal intensity obtained from the first radio signal.

A method of positioning a terminal, comprising:
- receiving a first radio signal generated through beamforming from a base station;
- obtaining a cell ID and a beam ID from the first radio signal;
- obtaining a received signal intensity of the first radio signal;
- and
- estimating a first position of the terminal by comparing a fingerprint in which a cell ID, a beam ID, and a received signal intensity are mapped to each point on a map with the cell ID, the beam ID, and the received signal intensity obtained from the first radio signal.
A positioning system comprising:
- a transceiver configured to receive a first radio signal generated through beamforming from a base station;
- and
- a first positioning device configured to estimate a first position of a terminal by comparing a fingerprint in which a cell ID, a beam ID, and a received signal intensity are mapped to each point on a map with a cell ID, a beam ID, and a received signal intensity obtained from the first radio signal.
A positioning system comprising:
- an inertial sensor;
- a transceiver configured to receive a first radio signal generated through beamforming from a base station or a second radio signal from at least one access point;
- a first positioning device configured to estimate a position of a terminal by comparing a fingerprint in which a cell ID, a beam ID, and a received signal intensity are mapped to each point on a map with a cell ID, a beam ID, and a received signal intensity obtained from the first radio signal;
- a second positioning device that estimates the position of the terminal through a received signal intensity or a round trip time obtained from the second radio signal;
- a third positioning device configured to obtain relative movement information of the terminal with respect to a reference position based on sensing information obtained through the inertial sensor and to obtain the position of the terminal based on the relative movement information of the terminal with respect to the reference position;
- and
- a combining portion configured to combine positioning results of at least one of the first positioning device, the second positioning device, and the third positioning device depending on whether each positioning device is available to obtain a final position of the terminal.
