Patent number: 11589314Abstract: Methods, systems, and devices for wireless communications are described. In a wireless communications system, a first user equipment (UE) may receive a message from a second UE via a set of one or more antennas, where a first symbol period and a second symbol period of the message include a duplicated signal, and the first symbol period is immediately prior to the second symbol period in a time domain. The first UE may calculate a correlation between first data included in the first symbol period and second data included in the second symbol period of the message for each antenna of the set of one or more antennas. In some cases, the first UE may power down at least one radio frequency chain based on the result of the calculated correlation satisfying a threshold value.Type: GrantFiled: July 2, 2021Date of Patent: February 21, 2023Assignee: QUALCOMM INCORPORATEDInventors: David Yunusov, Peer Berger, Lior Uziel, Shay Landis

Patent number: 11563614Abstract: Methods, systems, and devices for wireless communications are described. In one example, a transmitting device may identify first and second portions of data to include in a data transmission. The transmitting device may encode the second portion by a configuration of a first subset of resource elements. The transmitting device may transmit, via the data transmission, first signals representative of the first portion over the first subset and one or more second signals over a second subset of resource elements. A receiving device may receive the data transmission and may identify that the one or more second signals include content other than data of the data transmission. The receiving device may decode the first signals in order to identify the first portion and the configuration in order to identify the second portion. The receiving device may refrain from decoding the one or more second signals based on the identifying.Type: GrantFiled: March 2, 2021Date of Patent: January 24, 2023Assignee: QUALCOMM IncorporatedInventors: David Yunusov, Shay Landis, Ory Eger

Patent number: 11539571Abstract: IQ impairments compensation in sub-terahertz (sub-THz) communication is disclosed. According to some aspects, a user equipment (UE) determines an estimated in-phase (I) and quadrature phase (Q) impairment of the UE, the IQ impairment of the UE comprising a mismatch of phase and/or amplitude, between an I path and a Q path within an analog receiver circuitry of the UE, and reports the estimated IQ impairment of the UE to a base station (BS). The BS determines a pre-compensation to compensate for the estimated IQ impairment of the UE and uses the determined pre-compensation when transmitting to the UE.Type: GrantFiled: July 12, 2021Date of Patent: December 27, 2022Assignee: QUALCOMM IncorporatedInventors: David Yunusov, Shay Landis, Idan Michael Horn

Publication number: 20220070843Abstract: The present disclosure involves determining base station (BS) beams for communicating between a UE and the BS. The BS may use sensor data or beam management reporting history to assist with determining one or more appropriate beams. The sensor data may include camera images, radar data, or lidar data, and be used to model the cell environment served by the BS. The BS may obtain reporting data from multiple UEs over time indicating the quality of beams received by the UEs at various locations in the cell environment and model the cell environment based on the reporting data. The BS may associate beams with possible UE locations within the cell environment and use the associations to determine beams for communicating with a UE after determining the UE's location.Type: ApplicationFiled: September 1, 2020Publication date: March 3, 2022Inventors: Michael Levitsky, Guy Wolf, Assaf Touboul, Shay Landis, Sharon Levy, Noam Zach, David Yunusov, Peer Berger

Patent number: 11265815Abstract: Method and apparatus are provided for power saving by detecting empty symbols. In accordance with some implementation, a UE may determine that a data channel is not allocated to it by determining that there is no beam directed to it and there was no prior resource allocation to it. The UE upon such determination may enter sleep mode until the start of the next scheduling unit. This may result in reduction in power consumption compared to entering sleep mode after demodulating and decoding the control channel.Type: GrantFiled: April 30, 2019Date of Patent: March 1, 2022Assignee: QUALCOMM IncorporatedInventors: Shay Landis, Igor Gutman, Assaf Touboul, Gideon Shlomo Kutz, David Yunusov, Tal Oved
