Abstract: A mobile device may be configured to perform concurrent Satellite Positioning System and communication system operation, e.g. enabling an SPS receiver to continue to receive SPS signals in frequency bands that are interfered with due to aggressor transmission signals. A controllable filter, such as a selectable and/or tunable notch or lowpass filter is used to reject the aggressor transmission signals. The controllable filter may also attenuate some, but not all, frequencies in the SPS L1 band. To avoid losing complete access to these filtered SPS signal frequencies, the controllable filter is controlled, e.g., selected or tuned to these frequencies only when the aggressor transmission signal is active, and is otherwise turned off or tuned away from the SPS signal frequencies.

Abstract: Systems, apparatuses and methods are disclosed for estimating a signal travel time, and thus distance between transceivers, in an orthogonal frequency division multiplexing (OFDM) system. The signal travel time is measured between a transmit time (tT) and a receive window time (twindow) adjusted by the phase delay (TΦ). The phase delay (TΦ) is determined as a difference between a receive time (tR) and the receive window time (twindow). The receive time (tR) may be determined based on either an amplitude of the received signal at the receive window time (twindow) or when the received signal crosses a positive-negative axis. In synchronous systems, either a one-way time (OWT) or round-trip time (RTT) may be used for estimation. In asynchronous systems, an RTT is used for estimation.

Abstract: Position information obtained from a first wireless communication point may be associated with a second wireless communication point when signals are received from both the first and second wireless communication points, e.g., at or approximately at the same time. The wireless communication points may be, e.g., wireless network base station, access points, femto cells, etc. The position information may be a position for the first wireless communication point and a position uncertainty, which may be based on distances to the first and second wireless communication points, e.g., determined using wireless signal characteristics. The position information may be an uncertainty region determined based on position information from multiple wireless communication points. The position information associated with the second wireless communication point may be used in an application, e.g., obtaining a GPS position fix.
