Abstract: Disclosed are methods, systems and/or devices to calibrate a network time by acquisition of satellite positioning system (SPS) signals and different instances of time, and time-tagging SPS times according to the network time. In particular, the network time may be calibrated based, at least in part, on a first difference between first and second SPS times obtained at two SPS position fixes and a second difference between corresponding first and second time stamps.

Abstract: A method of triggering an action includes: determining that a mobile device is under water by: determining that an amplitude of a satellite positioning system (SPS) signal, or a wireless communication signal, or a combination thereof, received by the mobile device is below a threshold amplitude; or comparing data from a motion sensor of the mobile device with motion sensor data characteristic of entering water; or a combination thereof; determining that the mobile device has an action-inducing relationship to water; and taking the action in response to determining that the mobile device has the action-inducing relationship to water.

Abstract: System and method for temperature-calibration of a crystal oscillator (XO) in a mobile device. A temperature-calibration status of the XO is determined and a trigger condition related to temperature-calibration of the XO is detected. If the temperature-calibration status of the XO is not fully temperature-calibrated or if the XO has not been previously temperature-calibrated, a temperature-calibration session is initiated by an XO manager based on the condition, wherein a receiver is configured to receive signals and temperature-calibration of the XO is performed in a background mode based on the received signals. The condition based triggering ensures that the XO is temperature-calibrated prior to launch of any position based or global navigation satellite systems (GNSS) based applications on the mobile device. The trigger condition can include first use or power-on, charging, presence in an outdoor environment, variation in operating temperature, pre-specified time, and/or user input pertaining to the mobile device.

Abstract: Methods, apparatuses, and computer-readable media are described. In one example, a method, on a base station, for providing position measurements signals in a wireless communication network, comprises: determining a plurality of subcarriers for downlink transmission, wherein the plurality of subcarriers for downlink transmission comprise all subcarriers indicated in a resource block of a scheduled time of transmission within a scheduled transmission occasion, wherein the resource block comprises a plurality of symbol periods, wherein each symbol period of the plurality of symbol periods is for transmission of a symbol using one or more subcarriers of the plurality of subcarriers; and transmitting at the scheduled time of transmission, and using each subcarrier of the plurality of subcarriers, a wireless position measurement signal at the scheduled transmission occasion, the wireless position measurement signal being part of a sequence of wireless signals representing a position measurement signal bitstream.
