Abstract: Generally, this disclosure provides systems, devices, methods and computer readable media for sharing and coordination of motion data between subsystems of a mobile device. A device with motion data capabilities may include a plurality of sub-systems, at least one of the sub-systems may further include: a motion sensor to provide motion data associated with the device and a performance indicator module to provide performance quality data associated with the motion data. The device may further include a motion data interface to provide communication between the plurality of sub-systems such that a first of the sub-systems can selectively obtain motion data from a second of the sub-systems. The selection, by the first sub-system, may be based on the performance quality data associated with the second sub-system.

Abstract: Embodiments of the present disclosure are directed towards devices and methods for measurement report Quality of Position (QoP) validation in mobile station or mobile device (MS)-Assisted GNSS position systems. In one embodiment, a QoP value is calculated at a mobile device and a requested measurement report is only sent to a network server if the calculated QoP value exceeds a threshold value. In another embodiment, the QoP threshold value is included in the request for measurement report.
