Signalling for requesting preferred on-demand positioning reference signal (PRS) configurations or parameters from a transmitting device

A method of positioning performed by a location server, comprising:

• transmitting, to a network node, a first request requesting on-demand positioning reference signal (PRS) configurations supported by the network node;
• receiving a response from the network node, the response identifying one or more alternate PRS configurations, one or more alternate PRS parameters, or both defining one or more on-demand PRS resources the network node would prefer to transmit during a positioning session between the location server and one or more target UEs;
• and
• transmitting, to the network node, a second request requesting on-demand PRS transmission, the second request identifying at least one of the one or more alternate PRS configurations, at least one of the one or more alternate PRS parameters, or both.

A network node, comprising:

• a memory;
• at least one transceiver;
• and
• at least one processor communicatively coupled to the memory and the at least one transceiver, the at least one processor configured to:
• receive, via the at least one transceiver, from a location server, a first request requesting on-demand positioning reference signal (PRS) configurations supported by the network node;
• cause the at least one transceiver to transmit a response to the location server, the response identifying one or more alternate PRS configurations, one or more alternate PRS parameters, or both defining one or more on-demand PRS resources the network node would prefer to transmit during a positioning session between the location server and one or more target UEs;
• receive, via the at least one transceiver, from the location server, a second request requesting on-demand PRS transmission, the second request identifying at least one of the one or more alternate PRS configurations, at least one of the one or more alternate PRS parameters, or both;
• and
• cause the at least one transceiver to transmit at least one of the one or more on-demand PRS resources according to the at least one of the one or more alternate PRS configurations, the at least one of the one or more alternate PRS parameters, or both.
