Zusammenfassung:Disclosed are techniques for determining a timing resolution and a range of reported timing measurements used for position estimation. For example, in various embodiments, a user equipment (UE) may receive positioning beacons from multiple network nodes (e.g., different base stations, distant transmission points belonging to one base station, etc.), measure an observed time difference of arrival (OTDOA) between the received positioning beacons, and quantize the measured OTDOA according to a timing resolution and/or a range that depend at least in part on one or more signal parameters associated with the received positioning beacons. Accordingly, the UE may then transmit a report containing the quantized OTDOA to a network entity, which may correspond to one or more of the network nodes from which the positioning beacons were received (e.g., a serving base station) or a location server.
