Abstract: Disclosed are methods, systems and devices for addressing a jammer signal transmitted by a device that effects a signal received at a receiver. In a particular embodiment, an application content signal is encoded for transmission in a wireless transmission medium to provide symbol content where the symbol content comprises at least some symbols representing the application content signal. A receiver may be selectively blanked synchronized with at least a portion of the symbol content.

Abstract: Method, computer program product, and apparatus for signal tracking and decoding in GNSS are disclosed. In one exemplary implementation, a satellite receiver may be configured to receive a first sub-frame of a satellite signal. It defers a determination of validity of the first sub-frame until a preamble of a second sub-frame is received. The satellite receiver receives the preamble of the second sub-frame, and then determines whether there is a data decoding error of the first sub-frame using the first sub-frame and the preamble of the second sub-frame.

Abstract: Methods and systems for wireless communication are provided. In one example, a method comprises: receiving, by a mobile device, a radio beam, the radio beam being a directional beam that propagates along an angle of departure with respect to an antenna that transmits the radio beam; identifying, by the mobile device, at least one of: the radio beam or a base station that operates the antenna; determining, by the mobile device, a position of the mobile device based on identifying at least one of the radio beam or the antenna of the base station; and outputting, by the mobile device, the position of the mobile device.

Abstract: Disclosed are techniques for determining round-trip times (RTTs) between a user equipment (UE) and multiple base stations. In an aspect, the UE transmits an RTT measurement signal whose arrival time is measured by each of the base stations, and each of the base stations returns an RTT response signal whose arrival times are measured by the UE. In another aspect, the base stations each transmit an RTT measurement signal and the UE returns an RTT response signal. The receiver of the RTT measurement signal may include the measured arrival time in a payload of the RTT Response signal. Alternatively, the measured arrival time(s) of the RTT Measurement signal(s) and the transmission time(s) of the RTT Response signal(s) are sent in a separate message. The RTT signals can be wideband signals using low reuse resources.

Abstract: A wireless communication system includes: a first sub-system including a first radio and a second radio, each including a transceiver or a receiver; and a second sub-system coupled to the first sub-system and including: a first antenna configured to convey signals; a first tuner coupled to the first antenna; and a controller coupled to the first tuner, the controller being configured to cause the first tuner to adjust a characteristic of the first tuner; where the controller and/or the first tuner is configured to provide, to the first sub-system, an indication of an effect on operational performance of a portion of the second sub-system coupled to the second radio based on operation of the first tuner or the first antenna, or a combination thereof; where the first sub-system is configured to modify operation of the second radio based on the indication of the effect on operational performance.

Abstract: Techniques are provided which may be implemented using various methods and/or apparatuses in a mobile GNSS device to compensate for arm swing. An example of an method for compensating for arm swing according to the disclosure includes determining an arm swing signal, such that the arm swing signal is approximately sinusoidal with a period of approximately T seconds, determining a position signal measurement period, receiving a plurality of positioning signals at intervals corresponding to the position signal measurement period, and determining current position information based on the plurality of positioning signals.

Abstract: Methods and apparatuses are provided for use with mode switchable navigation radios and the like. The methods and apparatuses may be implemented to selectively switch between certain operating modes based, at least in part, one or more determinations relating to one or more satellite positioning signals and/or space vehicles.

Abstract: A reference signal may provide for enhanced bandwidth utilization to enable highly accurate position determination with relatively low bandwidth. For a given allocated bandwidth, a reference signal may use of only a portion of the allocated bandwidth by using plurality of sub-bands. In some cases, the sub-bands may be near the edges of the allocated band to maximize Gabor bandwidth.

Abstract: Disclosed are devices, systems and techniques for propagating a system time maintained at a mobile device in a lower power mode using a sleep counter advanced by an XO crystal oscillator. In one particular implementation, a mobile device obtains initial and subsequent satellite positioning system fixes while in a higher power mode. Between the initial and subsequent position fixes, the mobile device may transition to a lower power mode during which measurements of a temperature of the XO crystal oscillator may be obtained.
