Systems and Methods of Inter-Device Coordination for Sidelink Positioning

A method for wireless communications, the method comprising:

• receiving, by a first device, first information identifying a resource pool for sidelink (SL) positioning communications;
• receiving, by the first device, from a second device via a first inter-user-equipment-coordination (IUC) SL communication using one or more resources from the identified resource pool, an indication comprising second information about one or more sidelink positioning reference signal (SL-PRS) resources;
• selecting, by the first device, at least one of the one or more SL-PRS resources based at least on the received second information;
• and
• transmitting, by the first device, an SL-PRS using the selected at least one of the one or more SL-PRS resources.

An apparatus comprising memory and a processor, the processor coupled to the memory and configured to:

• receive first information identifying a resource pool for sidelink (SL) positioning communications;
• receive an indication comprising second information about one or more sidelink positioning reference signal (SL-PRS) resources, wherein the indication is received from a second device via a first inter-user-equipment-coordination (IUC) SL communication using one or more resources from the identified resource pool;
• select at least one of the one or more SL-PRS resources based at least on the received second information;
• and
• generate an SL-PRS for transmission using the selected at least one of the one or more SL-PRS resources.

A user equipment (UE) comprising:

• radio circuitry configured to enable wireless communications of the UE;
• and
• an apparatus communicatively coupled to the radio circuitry and configured to cooperate with the radio circuitry to cause the UE to:
• receive first information identifying a resource pool for sidelink (SL) positioning communications;
• receive, from a second device via a first inter-user-equipment-coordination (IUC) SL communication using one or more resources from the identified resource pool, an indication comprising second information about one or more sidelink positioning reference signal (SL-PRS) resources;
• select at least one of the one or more SL-PRS resources based at least on the received second information;
• and
• transmit an SL-PRS using the selected at least one of the one or more SL-PRS resources.
