An ambiguous cell may employ a Distributed Antenna System (DAS), one or more Remote Radio Heads (RRHs), repeaters or relays, or may broadcast the same Positioning Reference Signal (PRS) as another nearby cell. In example techniques, measurements of a radio source in an ambiguous cell (e.g. a DAS antenna element or RRH) may be used to identify the measured radio source. The measurements may be for the Observed Time Difference of Arrival (OTDOA) position method or the Enhanced Cell ID (ECID) position method. The determination of the measured radio source for an ambiguous cell may be used to improve a location estimate for a user equipment (UE)."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Support of OTDOA positioning using ambiguous cells","description":"Techniques are discussed for supporting positioning with ambiguous wireless cells.
