Abstract: Methods, systems, computer-readable media, and apparatuses for determining a position of a mobile device connected to a network are presented. 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: 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: 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.
