Patent number: 11800464Abstract: 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.Type: GrantFiled: July 24, 2020Date of Patent: October 24, 2023Assignee: QUALCOMM IncorporatedInventors: Jie Wu, Daniel Fred Filipovic, Emilija Milorad Simic, Vishal Agarwal

Patent number: 10044478Abstract: 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.Type: GrantFiled: July 9, 2015Date of Patent: August 7, 2018Assignee: QUALCOMM IncorporatedInventors: Amit Gopilal Jain, Emilija Milorad Simic, Bao Vinh Nguyen, Dominic Gerard Farmer, Arif Ehsan, Dinesh Subramani, Duong Anh Hoang, Timothy Paul Pals

Patent number: 9304209Abstract: Methods and systems for evaluating Global Navigation Satellite System (GNSS) signals are provided. Each of a first GNSS signal received by a GNSS receiver and a second GNSS signal received by the GNSS receiver is accessed. The second GNSS signal can have temporal fluctuations weaker than temporal fluctuations in the first GNSS signal. A delay between a sequence in the first GNSS signal and a corresponding sequence signal in the second GNSS signal is estimated and compared to a threshold. Upon determining that the delay exceeds the threshold, a location is estimated using both the first GNSS signal and the second GNSS signal.Type: GrantFiled: March 13, 2013Date of Patent: April 5, 2016Assignee: QUALCOMM IncorporatedInventors: Duong Anh Hoang, Emilija Milorad Simic, Timothy Paul Pals

Publication number: 20140004887Abstract: Systems and methods for temperature-calibration of an uncompensated XO in a mobile device during mobile device operation. The XO is temperature-calibrated based on assistance from wireless signals, such as from satellite source, and optionally from terrestrial sources such as WWAN, CDMA, etc. Based on one or more received wireless signals received at a receiver, corresponding frequency estimates of the XO are obtained and correlated with corresponding operating temperatures in a processor. Based on one or more samples of frequency estimates and associated temperatures, the XO is temperature-calibrated in the processor wherein a frequency-temperature (FT) model is formulated for the XO. The frequency of the temperature-calibrated XO can be determined from the FT model at any given temperature.Type: ApplicationFiled: February 22, 2013Publication date: January 2, 2014Applicant: QUALCOMM IncorporatedInventors: Dominic Gerard FARMER, Vishal AGARWAL, Emilija Milorad SIMIC, Daniel Fred FILIPOVIC, Sasidhar MOWA
