Patent number: 11811146Abstract: Methods, systems, and devices for wireless communication are described. A wireless repeater beamforms a receive signal, at a first antenna array. The repeater retransmits, via a second antenna array, a beamformed signal. The repeater may adjust the receive and/or transmit beam in order to avoid signal interference caused by the retransmission. The repeater may monitor an output of a power amplifier (PA) in a signal processing chain and adjust a gain to a PA driver to the PA and/or a gain to one or more low noise amplifiers (LNAs) in the signal processing chain in order to improve or maintain transmission stability in the repeater.Type: GrantFiled: February 12, 2020Date of Patent: November 7, 2023Assignee: QUALCOMM IncorporatedInventors: Raju Hormis, Junyi Li, Navid Abedini, Juergen Cezanne, Ozge Koymen

Patent number: 11792833Abstract: Methods, systems, and devices for wireless communications are described. A repeater may apply a frequency translation and a phase rotation adjustment to a transmitted signal to avoid radio frequency interference. For instance, wireless repeater may receive a signal from a first device on a first carrier frequency. The wireless repeater may identify one or more interfering signals affecting the reception or transmission of the signal. The wireless repeater may then perform a frequency translation from the first carrier frequency to the second carrier frequency, and may also apply a phase rotation adjustment corresponding to the frequency translation. The wireless repeater may retransmit the signal including the phase rotation adjustment over the second carrier frequency to a second device in the wireless network.Type: GrantFiled: April 23, 2020Date of Patent: October 17, 2023Assignee: QUALCOMM IncorporatedInventors: Raju Hormis, Junyi Li, Navid Abedini, Juergen Cezanne, Ozge Koymen

Patent number: 11792063Abstract: Methods, systems, and devices for wireless communications are described. A phase rotation adjustment may be applied in cases where a transmitted signal is heterodyned. For instance, a device (e.g., a base station, a user equipment (UE), a wireless repeater) may determine that a receiving device may receive a transmitted signal at a carrier frequency that is different from a carrier frequency used by a transmitting device (e.g., such as in the case of a wireless repeater relaying the signal from the transmitting device to the receiving device). A phase rotation adjustment may be applied by the device (e.g., the base station, UE, or wireless repeater) to account for the heterodyning. The phase rotation adjustment may be based on the carrier frequency used by the receiving device to receive the signal. In some cases, a receiving device may also apply the phase rotation adjustment following the demodulation of a received signal.Type: GrantFiled: April 23, 2020Date of Patent: October 17, 2023Assignee: QUALCOMM IncorporatedInventors: Raju Hormis, Junyi Li, Navid Abedini, Juergen Cezanne, Ozge Koymen

Publication number: 20230283336Abstract: Aspects of the present disclosure relate to utilizing an intelligent reflecting surface (IRS), a tracking algorithm, or both, to receive, calibrate, and maintain orbital angular momentum (OAM) signaling between wireless devices. The present disclosure describes a first wireless device transmitting spatial-multiple input-multiple output (MIMO) beams to the IRS such that reflected waves from the IRS form a spatial mixture of OAM modes. The IRS may reflect such OAM modes to a second wireless device for subsequent reflection (e.g., a second IRS), reception, calibration, and optimization. For example, the second wireless device may perform pattern recognition of the concentric OAM modes (e.g., by estimating ellipse geometry) to determine the modes of the OAM signaling. The second wireless device may also perform decorrelation, where small perturbations to the elliptical OAM geometry allow the second wireless device to perform one or more optimization techniques related to the OAM signaling.Type: ApplicationFiled: March 2, 2022Publication date: September 7, 2023Inventors: Mehmet Izzet Gurelli, Qiang Wu, Junyi Li, Tao Luo, Ozge Koymen, Navid Abedini, Mohammad Ali Tassoudji
