Configuration framework and positioning reference signal (prs) association mechanisms and triggering for reconfigurable intelligent surface (ris)-aided positioning and object sensing

A method of wireless positioning performed by a network entity, comprising:

• engaging in a positioning session or a sensing session with a user equipment (UE);
• determining reflection point object (RPO) information for at least one RPO that is capable of reflecting a waveform, the RPO information including at least location information for the at least one RPO;
• and
• transmitting the RPO information 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:
• engage in a positioning session or a sensing session;
• and
• receive, via the at least one transceiver, from a network entity, assistance data for at least one positioning reference signal (PRS) resource transmitted by a transmission point, the assistance data including a PRS resource location field indicating a geographic location of the transmission point, the assistance data further including reflection point object (RPO) information for at least one RPO that is capable of reflecting a waveform associated with the at least one PRS resource, the RPO information including at least location information for the at least one RPO.

A network entity, comprising:

• 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:

• determine reflection point object (RPO) information for at least one RPO that is capable of reflecting a waveform, the RPO information including at least location information for the at least one RPO;
• and
• cause the at least one transceiver to transmit the RPO information to the UE.
