Title:
ON-DEMAND POSITIONING REFERENCE SIGNAL SELECTION FOR DOUBLE DIFFERENCE POSITIONING SCHEMES
Document Type and Number:
WIPO Patent Application WO/2022/197909
Kind Code:
A3
Abstract:
Techniques are provided for configuring on-demand positioning reference signal (PRS) resources in double difference (DD) positioning methods. An example method for providing an on-demand positioning reference signal request includes receiving a plurality of positioning reference signal measurement values from a target user equipment and at least one reference node, determining one or more on-demand positioning reference signals based at least in part on signal identification information associated with each of the plurality of positioning reference signal measurement values, and sending an indication of the one or more on-demand positioning reference signals to either of the target user equipment, the at least one reference node, or both.
