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.

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: The disclosure generally relates to positioning techniques that can be used in a wireless communications network. For example, assistance data that includes predicted contents associated with messages that multiple neighboring nodes are configured to transmit at a synchronized time may be encoded and correlated with a signal received at one or more receive antennas on a user device. The correlation may be used to estimate a channel response from one or more transmit antennas at a current node that transmitted the signal to the one or more receive antennas on the user device, whereby an estimated time of arrival from the current node can be computed based at least in part on the estimated channel response.
