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.
