Abstract: The present disclosure relates to pseudo-randomization of unused resources at a medium access control layer (MAC) of a user equipment (UE). For example, the disclosure presents a method and an apparatus for determining that an uplink (UL) resource grant, associated with a first radio access technology (RAT), for the UE results in unused resources where there are a greater number of resources than available data for transmission at the UE, wherein the UE is configured to receive information associated with a second RAT, and wherein the first RAT is different from the second RAT, populating the unused resources, at a medium access control (MAC) layer, with pseudo-randomized bits, and transmitting at least a portion of the available data and the populated unused resources using the UL resource grant associated with the first RAT. As such, pseudo-randomization of unused resources at a medium access control layer (MAC) of a UE may be achieved.

Abstract: Techniques for managing power consumption of a Global Navigation Satellite System (GNSS) receiver of a mobile device are provided. These techniques include a method that includes deriving a GNSS search window for the GNSS receiver based on a position uncertainty (PUNC) and a time uncertainty (TUNC), selecting a GNSS search mode based on the GNSS search window and resources available for searching for signals from GNSS satellite vehicles (SVs), wherein an estimated power consumption associated with execution of a GNSS search associated with the GNSS search mode does not exceed a power consumption limit specified for the GNSS receiver conducting the GNSS search using the GNSS search mode, and estimating a position of the mobile device.

Abstract: A mobile device may use one or more outlier detectors to detect likelihoods that an outlier condition exists for a satellite positioning system (SPS) position fix. In some implementations, a method may comprise checking a position fix of a SPS receiver for consistency with assistance data used to generate a position fix. The method may further comprise determining whether to generate a new position fix using less than all of the assistance data based, at least in part, on results of the checking of the position fix.

Abstract: Techniques for supporting location services in a user plane location architecture such as Secure User Plane Location (SUPL) are described. In an aspect, a terminal informs a location server of service capabilities of the terminal. The location server uses the service capabilities to request only location services supported by the terminal and to avoid requesting unsupported location services. The terminal generates a message containing its service capabilities and sends the message via a user plane, e.g., SUPL. The location server receives the message, obtains the service capabilities of the terminal, and stores these service capabilities for future network-initiated location sessions with the terminal. The location server determines whether a location service is supported by the terminal based on the service capabilities of the terminal. The location server communicates with the terminal via the user plane for the location service if supported by the terminal.

Abstract: Methods, apparatuses, systems and computer-readable media for addressing the aging of oscillation (XO) crystals are presented. Some embodiments may determine a change of age of the XO crystal since last prior use of the XO crystal. Embodiments may then determine that at least one calibration parameter is not suitable for use in at least one calibration technique of the XO crystal, based on the change of age of the XO crystal. Embodiments may then determine at least one fresh calibration parameter configured to update the at least one calibration parameter for suitable use in the at least one calibration technique of the XO crystal.

Abstract: Methods and circuits can down convert at least a first RF signal on a first path in a first frequency band to provide a first IF signal. A second RF signal on second path in a second frequency band can be down converted to provide a second IF signal. The first IF signal and the second IF signal are interspersed in the frequency domain, and the first frequency band is different from the second frequency band. A combiner can combine at least part of the first IF signal and the second IF signal to provide a combined signal on an output signal path for reception by a digital processing circuit. The first IF signal or second IF signal can be a Zero IF (ZIF), very low IF (VLIF), or Low IF (LIF) signal.

Abstract: An attenuated satellite positioning system (SPS) signal is acquired using long integration over multiple navigation data bits. To produce a stable internal clock signal to perform the long integration, an external clock signal is received from a highly stable source, such as a wireless communication base station or a nearby femtocell. An internal oscillator is driven at a desired frequency that is aligned with the scaled frequency of the external clock signal to produce the stable internal clock signal. The SPS signal is received and integrated for an extended period using the internal clock signal. Predicted SPS data may be received from an external source and used to perform coherent integration. Alternatively, non-coherent integration may be performed. Additionally, a motion sensor may be used to determine if there is motion relative to the external clock source or to compensate for Doppler errors in the external clock signal due to motion.
