Abstract
An aspect is directed to signaling, to a target UE, a required reference signal for positioning (RS-P) measurement set and an optional RS-P measurement set (e.g., for a positioning session associated with a DDT procedure or a non-DDT procedure). In another aspect, a double differential timing (DDT) procedure is triggered based at least upon a trajectory of a target user equipment (UE). Another aspect is directed to a joint DDT (J-DDT) procedure involving multiple reference wireless nodes.
Claims17
A method of operating a position estimation entity, comprising:
- determining to trigger a joint double differential timing (J-DDT) procedure, the J-DDT procedure comprising a first differential timing (DT) procedure based on timing measurements between a target user equipment (UE) and each wireless node among a first set of wireless nodes, a second DT procedure based on timing measurements between a first reference wireless node and each wireless node among a second set of wireless nodes, and a third DT procedure based on timing measurements between a second reference wireless node and each wireless node among a third set of wireless nodes;
- and
- transmitting, to at least the target UE, the first reference wireless node and the second reference wireless node, requests to perform the J-DDT procedure based on the determination to trigger the J-DDT procedure.
A position estimation entity, 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:
- obtain first trajectory information associated with a target user equipment (UE);
- determine to trigger a double differential timing (DDT) procedure based on the first trajectory information, the DDT procedure comprising a first differential timing (DT) procedure based on timing measurements between the target UE and first and second wireless nodes, and a second DT procedure based on timing measurements between a reference wireless node and the first and second wireless nodes;
- and
- transmit, via the at least one transceiver, to at least the target UE and the reference wireless node, requests to perform the DDT procedure based on the determination to trigger the DDT procedure.
A position estimation entity, comprising:
- means for determining to trigger a joint double differential timing (J-DDT) procedure, the J-DDT procedure comprising a first differential timing (DT) procedure based on timing measurements between a target user equipment (UE) and each wireless node among a first set of wireless nodes, a second DT procedure based on timing measurements between a first reference wireless node and each wireless node among a second set of wireless nodes, and a third DT procedure based on timing measurements between a second reference wireless node and each wireless node among a third set of wireless nodes;
- and
- means for transmitting, to at least the target UE, the first reference wireless node and the second reference wireless node, requests to perform the J-DDT procedure based on the determination to trigger the J-DDT procedure.
