Request for on-demand positioning reference signal positioning session at a future time

A method of operating a position estimation entity, comprising:

• receiving a request to schedule an on-demand positioning reference signal (PRS) positioning session of a user equipment (UE) at a future time, wherein the request is configured to request a first set of parameters for the scheduled on-demand PRS positioning session, with an availability of one or more parameters of the first set of parameters at the future time being indeterminable when the request is received;
• determining, in response to the request and in advance of the future time, the availability of the one or more parameters at the future time;
• determining a PRS configuration for the scheduled on-demand PRS positioning session, wherein the PRS configuration includes a second set of parameters that is based at least in part on the determination of the availability of the one or more parameters at the future time;
• and
• transmitting, in response to the request and in advance of the future time, the PRS configuration to the UE.

A user equipment (UE), 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:
• transmit, via the at least one transceiver, to a position estimation entity, a request to schedule an on-demand positioning reference signal (PRS) positioning session of the UE at a future time, wherein the request is configured to request a first set of parameters for the scheduled on-demand PRS positioning session, with an availability of one or more parameters of the first set of parameters at the future time being indeterminable when the request is transmitted;
• and
• receive, via the at least one transceiver, in response to the request and in advance of the future time, a PRS configuration for the scheduled on-demand PRS positioning session, wherein the PRS configuration includes a second set of parameters that is based at least in part on the availability of the one or more parameters at the future time.

A position estimation entity, comprising:

• means for receiving a request to schedule an on-demand positioning reference signal (PRS) positioning session of a user equipment (UE) at a future time, wherein the request is configured to request a first set of parameters for the scheduled on-demand PRS positioning session, with an availability of one or more parameters of the first set of parameters at the future time being indeterminable when the request is received;

• and
• means for transmitting, in response to the request and in advance of the future time, the PRS configuration to the UE.
