On demand positioning in a wireless communication system

A method, performed in a location server, for obtaining position information of user equipment (UE) in a wireless communication system, the method comprising:

• receiving, from the UE, an indication comprising beam information defining beams that are suitable to be used for Positioning Reference Signals (PRS) for the UE;
• determining, by the location server, PRS scheduling information for upcoming transmission of the PRS based on the beam information that was received;
• transmitting, to the UE via a base station, the PRS scheduling information for upcoming transmission of the PRS based on the beam information that was received;
• triggering transmission of the PRS to the UE;
• and
• receiving, from the UE, measurements on the PRS that was transmitted to the UE,
• wherein the location server is remotely located from the base station.

A wireless electronic device used in a wireless communication system, the wireless electronic device comprising:

• a processor;
• and
• a memory coupled to the processor, the memory comprising computer readable program code embodied therein that, when executed by the processor, causes the processor to perform operations comprising:
• transmitting, to a location server, an indication comprising beam information defining beams that are suitable to be used for transmitting Positioning Reference Signals (PRS) to the wireless electronic device, for determination of PRS scheduling information by the location server based on the beam information from the wireless electronic device;
• receiving, from the location server, the PRS scheduling information for upcoming transmission of the PRS from a base station;
• performing measurements on the PRS based on the PRS scheduling information that was received;
• and
• providing the measurements to the location server,
• wherein the location server is remotely located from the base station.
