Determination of positioning reference signal resources in out-of-coverage sidelink-assisted cooperative positioning

A method for wireless communication performed at a target user equipment (UE), comprising:

• transmitting a request to perform a positioning procedure to at least one assisting UE over a sidelink between the at least one assisting UE and the target UE, wherein the target UE and the at least one assisting UE are both out of network coverage;
• determining, based at least on the request, a set of time resources, frequency resources, or both on which to transmit one or more positioning reference signals to the at least one assisting UE for the positioning procedure, wherein the set of time resources, frequency resources, or both is determined based on a deterministic function of one or more parameters;
• and
• transmitting the one or more positioning reference signals to the at least one assisting UE via the set of time resources, frequency resources, or both.

An assisting 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:
• receive a request to perform a positioning procedure from a target UE over a sidelink between the assisting UE and the target UE, wherein the assisting UE and the target UE are both out of network coverage;
• determine, based at least on the request, a set of time resources, frequency resources, or both on which to transmit one or more positioning reference signals for the positioning procedure, wherein the set of time resources, frequency resources, or both is determined based on a deterministic function of one or more parameters;
• and
• cause the at least one transceiver to transmit the one or more positioning reference signals to the target UE via the set of time resources, frequency resources, or both.
