Patent number: 11637723Abstract: Methods, systems, and devices for wireless communication are described. In some systems (e.g., Wi-Fi systems), a transmitting device such as an access point (AP) or mobile station (STA), may identify a number of spatial streams for a data transmission that is less than a number of transmit antennas, and may transmit a packet over a channel. In a first implementation, the packet may be formatted in a multi-user frame format, with a number of long training field (LTF) symbols equal to the number of transmit antennas. In a second implementation, the packet may be a null data packet (NDP), and the device may transmit a separate data packet. In a third implementation, the packet may be formatted in single-user frame format with a modified LTF. A receiving device may receive the packet, and may perform channel estimation and power amplifier (PA) distortion cancellation based on the received packet.Type: GrantFiled: November 13, 2020Date of Patent: April 25, 2023Assignee: QUALCOMM INCORPORATEDInventors: Lin Yang, Bin Tian, Jialing Li Chen, Louay Jalloul, Vincent Knowles Jones, IV, Ning Zhang, Chi-Lin Su, Ahmad Abdulrahman Mohammed

Publication number: 20200305124Abstract: A system and method are disclosed that may allow for enhanced gain control for two radios. In an example method, a first radio may receive a wireless signal on a first frequency band, the wireless signal including at least a header and a payload. A first gain control operation may be performed based at least in part on information in the header of the wireless signal. A second radio may be determined to initiate a transmission on a second frequency coinciding with the first frequency band before reception of the wireless signal is completed, where the second radio is co-located with the first radio. A second gain control operation may be performed based at least in part on an expected interference associated with the transmission from the second radio, and one or more gain levels may be adjusted for reception of the wireless signal, based on the second gain control operation.Type: ApplicationFiled: March 20, 2019Publication date: September 24, 2020Inventors: Shi-Cong Yang, Louay Jalloul, Olaf Josef Hirsch, Tianqi Wang, Qinfang Sun

Publication number: 20200274592Abstract: This disclosure provides methods, devices and systems for obtaining and providing channel feedback. In some implementations, a beamformee provides channel feedback to a beamformer that enables the beamformer to construct and independently precode two or more different sets of spatial streams for transmission to the beamformee. The independent precoding of the different sets of spatial streams ensures that the decodings of the different sets of spatial streams may be decoupled from one another at the beamformee. To provide the channel feedback, the beamformee partitions a channel estimate into two or more sub-estimates prior to performing a channel decomposition. In some implementations, the beamformee determines null-space-based projections of the sub-estimates before performing the channel decomposition.Type: ApplicationFiled: February 5, 2020Publication date: August 27, 2020Inventors: Yashwanth MANDULA, Gopala Krishna Murthy VEMULA, Suresh CHANDRASEKARAN, Ashutosh Deepak GORE, Swaroop VENKATESH, Louay JALLOUL, Ahmad Abdulrahman MOHAMMED, Yen-Feng LEE, Pedram PAYSARVI HOSEINI, Chi-Lin SU, Youhan KIM

Publication number: 20190379434Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for detecting motion using wireless local area network (WLAN) communications. A first WLAN device having multiple antennas (radios) may determine a metric based on differences in spatial signal processing characteristics between the multiple antennas. By comparing changes in the metric over a plurality of wireless signals over time, the first WLAN device may detect motion in the environment near the first WLAN device. The spatial signal processing characteristics may be based on received WLAN communications from a second WLAN device, based on beamforming feedback from the second WLAN device, or based on wireless signal reflections detected by the first WLAN device. Various techniques may be used to adjust or mitigate random phase differences between two antennas on some tones. Motion detection based on WLAN communications may trigger activities or notifications by the first WLAN device.Type: ApplicationFiled: June 5, 2019Publication date: December 12, 2019Inventors: Erik David Lindskog, Xiaoxin Zhang, Youhan Kim, Louay Jalloul, Kurt Erwin Landenberger, Youngsin Lee, Srinivasarao Kode, Manishekar Chandrasekaran
