Abstract
A computer-implemented method and a server for device positioning. The computer-implemented method includes receiving a control message from a positioning server. The control message indicates a set of channels associated with an area and time periods for monitoring the set of channels. At least one measurement of a signal from at least one of a reference device for the area and a target device is obtained, according to the control message, with the reference device being located at a predefined position with respect to the area. The at least one measurement is reported to the positioning server for determining a position of the target device with respect to the area.

A computer-implemented method comprising:
- receiving a control message from a positioning server, the control message indicating a set of channels associated with an area and time periods for monitoring the set of channels;
- obtaining, according to the control message, at least one measurement of a signal from at least one of a reference device for the area and a target device, the reference device being located at a predefined position with respect to the area;
- and
- reporting the at least one measurement to the positioning server for determining a position of the target device with respect to the area.
A computer-implemented method comprising:
- receiving a control message from a positioning server, the control message indicating a set of channels associated with an area and time periods for monitoring the set of channels;
- obtaining, according to the control message, at least one measurement of a signal from at least one of a reference device for the area and a target device, the reference device being located at a predefined position with respect to the area;
- reporting the at least one measurement to the positioning server for determining a position of the target device with respect to the area,
- wherein obtaining the at least one measurement comprises:
- determining the set of channels and the time periods for monitoring the set of channels from the control message;
- monitoring each of the set of channels during a respective time period of the time periods;
- and
- generating the at least one measurement by measuring on the monitored channel.
