Method and device for controlling positioning reference signal configuration in wireless communication system

A method performed by a network entity in a communication system, the method comprising:

• transmitting, to a user equipment (UE), pre-defined positioning reference signal (PRS) configuration information;
• receiving, from the UE, a request for an on-demand PRS, wherein the request for the on-demand PRS includes periodicity information associated with a subcarrier spacing (SCS) of a synchronization signal block (SSB);
• and
• as a response to the reception of the request for the on-demand PRS, determining a need for a PRS transmission or a change of an ongoing PRS transmission.

A user equipment (UE) in a communication system, the UE comprising:

• a transceiver;
• and
• a controller coupled with the transceiver, and configured to:
• receive, from a network entity performing a location management function (LMF), pre-defined positioning reference signal (PRS) configuration information;
• transmit, to the network entity performing the LMF, a request for an on-demand PRS, wherein the request for the on-demand PRS includes periodicity information associated with a subcarrier spacing (SCS) of a synchronization signal block (SSB);
• and
• as a response to the transmission of the request for the on-demand PRS, receive, from the network entity performing the LMF, PRS configuration information.
