Signaling minimum and maximum positioning range indications and zone identifiers for sidelink positioning

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, via the at least one transceiver, a positioning request from a target UE, the positioning request including a zone identifier (ID) identifying a zone in which the target UE is located;
• determine, based on the assisting UE being outside a minimum positioning range (Min-PR) and within a maximum positioning range (Max-PR) of the target UE, whether to transmit a positioning response to the target UE;
• and
• transmit, via the at least one transceiver, based on the assisting UE being within the Min-PR of the target UE, the positioning response to the target UE.

A target 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, a positioning request to at least one assisting UE, the positioning request including a first zone identifier (ID) of a three-dimensional zone in which the target UE is located;
• and
• receive, via the at least one transceiver, from the at least one assisting UE, a positioning response, the positioning response including a second zone ID of a second zone in which the at least one assisting UE is located.

A target 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, via the at least one transceiver, a set of zone identifiers (IDs), each zone ID in the set of zone IDs associated with one or more metrics indicating a level of sidelink positioning accuracy associated with that zone ID;
• and
• engage in a sidelink positioning session based on the set of zone IDs.

An assisting user equipment (UE), comprising:

• means for receiving a positioning request from a target UE, the positioning request including a zone identifier (ID) identifying a zone in which the target UE is located;
• means for determining, based on the assisting UE being outside a minimum positioning range (Min-PR) and within a maximum positioning range (Max-PR) of the target UE, whether to transmit a positioning response to the target UE;
• and
• means for transmitting, based on the assisting UE being within the Min-PR of the target UE, the positioning response to the target UE.

A non-transitory computer-readable medium storing computer-executable instructions that, when executed by an assisting user equipment (UE), cause the UE to:

• receive a positioning request from a target UE, the positioning request including a zone identifier (ID) identifying a zone in which the target UE is located;
• determine, based on the assisting UE being outside a minimum positioning range (Min-PR) and within a maximum positioning range (Max-PR) of the target UE, whether to transmit a positioning response to the target UE;
• and
• transmit, based on the assisting UE being within the Min-PR of the target UE, the positioning response to the target UE.
