    Abstract: Disclosed are techniques for positioning. In an aspect, a positioning entity obtains a plurality of pairs of timing measurements based on a plurality of pairs of ranging messages exchanged on a plurality of bandwidths, determines a plurality of range measurements based on the plurality of pairs of timing measurements, each range measurement of the plurality of range measurements based on one pair of the plurality of pairs of timing measurements, determines a weight for each range measurement of the plurality of range measurements based at least on a bandwidth of the plurality of bandwidths of a pair of timing measurements of the plurality of pairs of timing measurements used to determine the range measurement, and determines a weighted mean of the plurality of range measurements based at least on the plurality of range measurements and weights of the plurality of range measurements.

    Abstract: During positioning of a user equipment (UE), for example, during an emergency call, a civic location of the UE may be determined. For example, during a location session in a wireless network, a UE may detect a WiFi access point (AP) and obtain the civic location of the WiFi AP from the AP. The UE may provide the civic location to a location server in the wireless network, which may treat the civic location as the civic location of the UE. The location server may validate the civic location using a geodetic location, e.g., obtained based on measurements from a satellite positioning system and/or base stations in the wireless network. The location server may further verify that the UE is proximate to the WiFi AP using WiFi positioning measurements performed by the UE. The validated civic location can be provided to an external client, e.g. a PSAP.
