Abstract:
Methods and apparatus to provide assistance data for satellite navigation in a wireless communication device are disclosed. Processing circuitry in the wireless communication device determines whether to obtain assistance data for navigation based on a set of criteria. The set of criteria include one or more of a property of a geographic region in which the wireless communication device operates, a satellite signal quality estimate measured by the wireless communication device, and a user setting of the wireless communication device. When the set of criteria indicates that assistance data for navigation is beneficial for satellite navigation in the wireless communication device, the processing circuitry obtains one or more sets of assistance data. The processing circuitry configures operation of the wireless communication device for navigation based at least in part on the one or more sets of assistance data obtained.
