Network assisted position measurements

A reference device formed by an IOT device,

• in a radio resource control connection mode and/or
• configured to be triggered on request by a base station or by a location server with a wake-up signal or through an extended discontinuous reception mechanism for transmission operations, in order to provide an opportunity to repeat a signal and/or enhance the ability of a target device to receive the signal from the reference device,
• wherein the transmitted signal
• is configured to be triggered by the base station or by the location server or
• is configured to be a timely scheduled transmission of the reference device.

A system comprising a base station or a location server, a target device and one or more reference devices formed by an IOT device,

• in a radio resource control connection mode and/or
• configured to be triggered on request by a base station or by a location server with a wake-up signal or through an extended discontinuous reception mechanism for transmission operations, in order to provide an opportunity to repeat a signal and/or enhance the ability of a target device to receive the signal from the reference device,
• wherein the transmitted signal
• is configured to be triggered by the base station or by the location server or
• is configured to be a timely scheduled transmission of the reference device,
• wherein the system is configured to perform a method determining the position of a target device within a communication network, the method comprising:
• receiving information about a transmitting time and frequency allocation of a reference device, formed by an internet of things, IOT, device, within the communication network at the target device from a base station or a location server;
• expecting a signal transmitted by the reference device and performing a radio frequency, RF, measurement by the use of the information, so as to acquire a measurement value dependent on a distance between the target device and the reference device, wherein the target device performs the RF measurement on the expected transmitted signal;
• wherein the base station or the location server triggers the reference device to transmit the signal;
• and
• wherein the method comprises calculating the position of the target device based on the results of the RF measurements.

A non-transitory digital storage medium having a computer program stored thereon to perform the method for determining the position of a target device within a communication network, the method comprising:

• receiving information about a transmitting time and frequency allocation of a reference device, formed by an internet of things, IOT, device, within the communication network at the target device from a base station or a location server;
• expecting a signal transmitted by the reference device and performing a radio frequency, RF, measurement by the use of the information, so as to acquire a measurement value dependent on a distance between the target device and the reference device, wherein the target device performs the RF measurement on the expected transmitted signal;
• wherein the base station or the location server triggers the reference device to transmit the signal;
• and
• wherein the method comprises calculating the position of the target device based on the results of the RF measurements,
• when said computer program is run by a computer.
