Abstract
The present embodiments relate to a method and device for obtaining location information of a terminal by using a wireless communication system. Provided according to an embodiment is a device for acquiring the location information of a terminal, the device comprising at least one downlink signal receiver, at least one uplink signal receiver, and a controller for controlling the downlink signal receiver and uplink signal receiver, wherein the controller configures uplink resource assignment information on the basis of control information received by the downlink signal receiver and determines whether an uplink signal is received, on the basis of the uplink resource allocation information.
Claims14
A base station comprising:
- a terminal information determination unit configured to determine whether a terminal is a target terminal whose location is required to be measured;
- and a transmission configuration determination unit configured to determine uplink resource allocation information for the terminal based on a result of the determination, wherein the uplink resource allocation information that improves a reception performance at a signal measurement device for an uplink signal transmitted by the target terminal is compared with the reception performance at the signal measurement device for the uplink signal transmitted by another terminal which is not the target terminal.
A method comprising:
- determining whether a terminal is a target terminal whose location is required to be measured;
- and determining uplink resource allocation information for the terminal based on a result of the determination, wherein the uplink resource allocation information that improves reception performance at a signal measurement device for the uplink signal transmitted from the target terminal is compared with the reception performance at the signal measurement device for the uplink signal transmitted from another terminal which is not the target terminal.
A location measurement server comprising:
- a communication unit configured to receive information on transmission power of an uplink signal transmitted by a target terminal from a base station, and receive information on reception power of the uplink signal transmitted by the target terminal from a signal measurement device;
- and
- a location calculation unit configured to determine location information of the target terminal based on the information on the transmission power of the uplink signal and the information on the reception power of the uplink signal or to determine the propagation attenuation between the signal measurement device and the target terminal.
