Patent number: 10999886Abstract: Various aspects related to techniques for harmonization between common reference signal (CRS) and demodulation reference signal (DM-RS) based transmission modes (TMs) in unlicensed spectrum are described. In one aspect, a downlink/uplink (DL/UL) subframe configuration may be signaled for each subframe. Information provided by the DL/UL subframe configuration may indicate whether the respective downlink subframe is a single-frequency network (MBSFN) subframe (associated with DM-RS-based TM) or a non-MBSFN subframe (associated with CRS-based TM). In another aspect, periodic as well as aperiodic channel state information (CSI) reporting requests may be supported. In yet another aspect, discontinued reception (DRX) wake ups for unlicensed carriers may be explicitly or implicitly indicated to a user equipment (UE) via a carrier in a licensed spectrum.Type: GrantFiled: August 9, 2016Date of Patent: May 4, 2021Assignee: QUALCOMM IncorporatedInventors: Peter Gaal, Srinivas Yerramalli, Durga Prasad Malladi, Yongbin Wei, Alexei Yurievitch Gorokhov, Brian Banister, Michael Lee McCloud, Tao Luo, Supratik Bhattacharjee, Chengjin Zhang, Ravi Teja Sukhavasi

Patent number: 10728080Abstract: Methods, systems, and devices for wireless communication are described. A transmitter, such as a user equipment and/or a base station, may perform polar coding to encode bits. The polar coding may be associated with a plurality of component channels associated with a polar code length. The transmitter may interleave the encoded bits. The transmitter may map the interleaved encoded bits to a modulation symbol. The interleaving and mapping of each encoded bit may be based on an asymmetry of a polar code construction. The transmitter may transmit the interleaved encoded bits based on the mapping.Type: GrantFiled: February 9, 2017Date of Patent: July 28, 2020Assignee: QUALCOMM IncorporatedInventors: Hari Sankar, Jing Jiang, Alexei Yurievitch Gorokhov, Joseph Binamira Soriaga, Brian Banister

Publication number: 20180317045Abstract: 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.Type: ApplicationFiled: April 28, 2017Publication date: November 1, 2018Inventors: Jordan Cookman, Jie Wu, Brian Banister, Yongle Wu

Patent number: 8781426Abstract: Techniques for controlling operation of control loops in a receiver are described. The operation of at least one control loop is modified in conjunction with a change in operating state, which may correspond to a change in linearity state, gain state, operating frequency, antenna configuration, etc. A change in linearity state may occur when jammers are detected and may cause bias current of analog circuit blocks to be adjusted. The at least one control loop to be modified may include a DC loop, an AGC loop, etc. The operation of a control loop may be modified by disabling the control loop or changing its time constant prior to changing operating state, waiting a predetermined amount of time to allow the receiver to settle, and enabling the control loop or restoring its time constant after waiting the predetermined amount of time.Type: GrantFiled: November 16, 2006Date of Patent: July 15, 2014Assignee: QUALCOMM IncorporatedInventors: Steven C.
