In aspects, a listening node determines a first time of arrival (ToA) at the listening node of a first radio frequency (RF) signal sent by a transmission-reception point (TRP) to the UE, determines a second ToA at the listening node of a second RF signal sent by the UE to the TRP, determines a time difference between the first ToA and the second ToA, and enables a positioning entity to estimate a location of the UE based on the time difference. The positioning entity calculates a distance between the listening node and the UE based on the time difference, a propagation time between the TRP and the listening node, a propagation time between the TRP and the UE, and a time difference between a ToA of the first RF signal at the UE and a transmission time of the second RF signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Round-trip-time (RTT)-based positioning with listening nodes","description":"Disclosed are techniques for positioning a user equipment (UE).
