Abstract: Disclosed is a method and apparatus for exploiting Radio Access Technology (RAT) system information blocks for global navigation satellite system (GNSS) positioning. The method may include processing, by a mobile device with carrier aggregation, a voice call via a first RAT, the processing of the voice call causing second RAT capabilities of the mobile device to go out of service. The method may also include accessing a communications network using the second RAT with an available receiver of the mobile device during the voice call via the first RAT. The method may also include obtaining, with the available receiver, timing information from one or more broadcast system information blocks of the second RAT, and determining a time based, at least in part, on the obtained timing information.

Abstract: Disclosed is a method and apparatus for performing a positioning process utilizing wireless communication network reference signals. The method may include processing, by a mobile device with carrier aggregation, a voice call via a first Radio Access Technology (RAT), the processing of the call causing second RAT capabilities of the mobile device to go out of service. The method may also include obtaining assistance data that includes information for capturing reference signals of a wireless communications network suitable for performing a positioning process with the mobile device during the voice call over the first RAT. Furthermore, based on the obtained assistance data, the method may include searching for the reference signals using an available receiver of the mobile device to access the wireless communications network. The method may also include providing signal measurements generated from captured reference signals to a position determining entity.
