    Abstract: Disclosed are implementations that include a method, generally performed at a mobile device, including receiving one or more wireless signals transmitted from a wireless node, with the wireless node being configured to operate in at least a first mode of operation to transmit wireless transmissions comprising one or more subframes configured according to a pre-determined first pattern of cell-specific reference signals (CRS) for the wireless node. The method also includes deriving, based on the received one or more wireless signals, at least one resultant signal attribute indicative of an actual CRS pattern for the received one or more wireless signals, and determining whether the at least one resultant signal attribute derived based on the received one or more wireless signals deviates from a corresponding expected at least one signal attribute associated with wireless signals including cell-specific reference signals produced according to the pre-determined first pattern of CRS.

    Abstract: Methods, systems, computer-readable media, and apparatuses for crowdsourcing the synchronization status of a network are presented. In various embodiments, a server receives a synchronization status of a base station associated with the network. If the synchronization status indicates that the network is synchronous, the server collects information for computing time correction data. The server may send the time correction data to the mobile device for use in determining the position of the mobile device when the mobile device is connected to the synchronous network.

    Abstract: A method of providing pressure information from a mobile device includes: measuring a barometric pressure at the mobile device; determining a present barometric pressure based on the measured barometric pressure; and sending, from the mobile device toward a server, the present barometric pressure. The server may determine an altitude for the mobile device based on the present barometric pressure and a known reference pressure for a known altitude. The method may further include providing pressure statistics and/or calibration points by the mobile device to the server where the calibration points include pressure measurements for known or determinable locations. The calibration points may enable the server to determine a calibration value to enable an adjustment or correction to the measured barometric pressure.

    Abstract: A UE includes: at least one sensor configured to provide at least one sensor measurement; and a processor configured to: determine first and second ranges between the UE and a positioning signal source based on first and second positioning signal measurements of first and second positioning signals from the positioning signal source corresponding to first and second times; determine whether a selected range of the first range or the second range is a multipath range based on the first range, the second range, and movement of the UE between the first time and the second time indicated by the at least one sensor measurement; and discount use of the selected range in a positioning technique in response to the selected range being determined to be a multipath range.

In various embodiments, the mobile device obtains a synchronization status of the network associated with one or more base stations. If the synchronization status indicates that the network is synchronous, the mobile device determines the position of the mobile device using previously collected crowdsourced time correction data for the synchronous network.

    Abstract: Determining the early arrival path (EAP) based on a channel energy response (CER) can involve the use one or more masks to identify one or more peaks in the CER. Masks can be applied to the CER in an iterative process that can help identify the earliest peak corresponding to the EAP. Alias cancelation may also be implemented.
