Publication number: 20240063928Abstract: In some implementations, a mobile device may perform a plurality of signal strength measurements of a radio frequency (RF) signal transmitted by a satellite, wherein performing the plurality of signal strength measurements occurs over a period of time during which the mobile device is subject to a movement. The mobile device may determine, for each signal strength measurement of the plurality of signal strength measurements, a respective orientation of the mobile device corresponding to when the respective signal strength measurement was performed. The mobile device may determine a target orientation for the satellite-based communications based at least in part on a value of a particular signal strength measurement of the plurality of signal strength measurements and the respective orientation of the mobile device corresponding to the particular signal strength measurement. The mobile device may provide guidance for rotating the mobile device to the target orientation.Type: ApplicationFiled: August 19, 2022Publication date: February 22, 2024Inventors: Udayan BHAWNANI, Francesco GRILLI, Junsheng HAN, Carl HARDIN, Jonathan KIES, Victor KULIK, Vanitha Aravamudhan KUMAR, Nirupama LOCANINDI, Vinay PARADKAR, Manmeet SINGH

Patent number: 11889436Abstract: The transmission and reception group delay in a front end structure of a mobile device may be determined using closed loop calibration. The closed loop may be a near field radiated closed loop between pairs of antennas in an antenna array of the mobile device. The delay based on time of transmission and time of reception may be measured for a plurality of pairs of antennas, from which the transmit and receive group delay within a single path may be determined. The propagation delay of the signal between antennas may be included in the group delay calibration for increased accuracy. In another implementation, a conducted closed loop, e.g., in the transceiver or in a radio frequency switching network may be used to calibrate the group delay. Pre-characterization of the delay caused by components between the closed loop and antennas may be included in the group delay calibration for increased accuracy.Type: GrantFiled: August 17, 2020Date of Patent: January 30, 2024Assignee: QUALCOMM IncorporatedInventors: Jay King, Alexander Dorosenco, Muhammad Sayed Khairy Abdelghaffar, Joseph Binamira Soriaga, Carl Hardin, Alexandros Manolakos, James Krysl, Michael Allen Kongelf, Krishna Kiran Mukkavilli, Tingfang Ji, Joseph Patrick Burke

Patent number: 11856528Abstract: Methods, systems, and devices for wireless communications are described. Some wireless communications systems may support adaptation of digital pre-distortion (DPD) coefficients based on a temperature of a user equipment (UE). The UE may determine a power offset value based on a first temperature value associated with a training procedure for the UE, a second temperature value associated with the UE, and a constant value. The training procedure may be associated with multiple sets of coefficients for the UE. The UE may apply the power offset value to a transmission power level for transmission of a message. The UE may determine a set of coefficients of the multiple sets of coefficients based on the training procedure and the power offset value applied to the transmission power level. The UE may apply the coefficients to a DPD engine of the UE to generate the message for transmission at the transmission power level.Type: GrantFiled: January 10, 2022Date of Patent: December 26, 2023Assignee: QUALCOMM IncorporatedInventors: Igor Gutman, Robert Zokaim, Oren Matsrafi, Yehezkel Hadid, Ghaith Shabsigh, Rahul Malik, Carl Hardin, Damin Cao, Michael Lee McCloud

Patent number: 11711120Abstract: Various aspects of the present disclosure generally relate to wireless communication. A wireless communication device may have an apparatus that aligns the non-linearity between transmit chains of the wireless communication device that are driven by the same digital port. The apparatus may adjust an amplification power out or an amplification saturated power to adjust a ratio between the amplification saturated power and the amplification power out for one or more transmit chains of the wireless communication device. The apparatus may adjust the ratios of transmit chains to align the ratios of the transmit chains for more consistent management of non-linear characteristics of the chain components. Numerous other aspects are described.Type: GrantFiled: April 29, 2022Date of Patent: July 25, 2023Assignee: QUALCOMM IncorporatedInventors: Alexander Sverdlov, Igor Gutman, Carl Hardin, Michael Lee McCloud, Robert Zokaim

Patent number: 11622281Abstract: A user equipment (UE) includes a first communication component configured to use a first frequency band, such as ultra-wide band (UWB), and a second communication component configured to use an intermediate frequency (IF) band that overlaps with the UWB band, such as an IF millimeter wave (mmWave) band. The second communication component conducts an IF signal along an internal signal conduction line that may interfere with UWB processing. A processor of the UE is configured to detect an indication of such interference, and, in response to the indication of interference, control the second communication component to adjust a characteristic of the IF band signal to mitigate the interference, such as by reducing its signal strength. The amount by which the IF band signal strength is reduced may be controlled to achieve a desired tradeoff between various performance metrics, such as power consumption and quality of service.Type: GrantFiled: February 9, 2021Date of Patent: April 4, 2023Assignee: QUALCOMM IncorporatedInventors: Carl Hardin, Brian Clarke Banister, Shrenik Patel, Michael Kohlmann, Liang Zhao, Le Nguyen Luong, Tevfik Yucek, Roland Rick, Shriram Gurumoorthy, Francis Ngai

Patent number: 11202264Abstract: Some techniques and apparatuses described herein protect components of a user equipment (UE), such as a low noise amplifier (LNA), from internal interference. For example, the LNA may be disconnected from a receive chain during periods of high internal interference, and may be reconnected to the receive chain during periods of low internal interference. Furthermore, some techniques and apparatuses described herein improve performance by adjusting operations of the UE to account for and/or offset increased internal interference due to a receive chain that does not include a surface acoustic wave (SAW) filter to remove unwanted radio frequency signals. For example, one or more operations of a baseband processor may be modified to account for the increased internal interference. Additionally, or alternatively, reporting of channel state information may be modified to account for increased internal interference of the UE. Additional details are described herein.Type: GrantFiled: July 16, 2019Date of Patent: December 14, 2021Assignee: QUALCOMM IncorporatedInventors: Steven Charles Ciccarelli, Vikas Mahajan, Tae Min Kim, Supratik Bhattacharjee, Chitaranjan Pelur Sukumar, Ashok Mantravadi, Pooyan Amini, Alberto Rico Alvarino, Carl Hardin

Patent number: 10931498Abstract: Phase variations between a transmitter (TX) waveform and a receiver (RX) waveform produced by a TX Phase-Locked-Loop (PLL) and a RX PLL, respectively, is a source of error in processing delay calibration used, e.g., in Round Trip Time (RTT) estimation. While a TX waveform and a RX waveform have a constant phase delay while in steady state conditions, during transient times, e.g., at start up or reset, the phase delay may vary by as much as ±180°, which at baseband frequencies of 50 MHz, introduces a random delay variations of as much as ±10 nsec, which is undesirable for fine position estimation using RTT. The phase delay variation between the TX waveform and RX waveform may be reduced or eliminated using a phase correction signal generated using the output signals of the TX PLL and RX PLL.Type: GrantFiled: November 13, 2019Date of Patent: February 23, 2021Assignee: QUALCOMM IncorporatedInventors: Alexander Dorosenco, Carl Hardin, Joseph Patrick Burke, Joseph Binamira Soriaga, Jay King
