In an aspect, the UE measures a positioning reference signal (PRS) from a first evolved NodeB (eNB) for a first secondary cell (Scell) and a second PRS from a second eNB for a second Scell. The UE reports the first and second PRS measurements and the first and second PRS measurement times to a location server. In an aspect, the first and second PRS are configured according to a common PRS configuration. The location server also receives transmission times of the PRS signals from the first and second eNBs. Using the measurement and transmission times, the location server can associate the first PRS measurement to the first eNB and the second PRS measurement to the second eNB, thereby assisting the location server to obtain a location for the UE."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Optimized observed time difference of arrival (OTDOA) in licensed-assisted access (LAA)","description":"Disclosed are techniques for determining a location of a user equipment (UE) communicating over a shared communication medium in unlicensed spectrum.
