Patent number: 11757486Abstract: Systems, methods, and devices for operating in either frequency division duplexing (FDD) or time division duplexing (TDD) for wireless communications using the same electrical balance duplexer (EBD) circuitry in a transceiver device are provided. A series of switches may selectively couple components of the EBD, such as a low noise amplifier (LNA), a power amplifier (PA), and balancing impedance, to ground based on selected operation mode (e.g., FDD or TDD) while reducing insertion loss of the receiver (RX) and transmitter (TX) signals. Tuned matching network blocks for the LNA and PA may be used in addition to the series of switches to provide impedance matching for additional reduction of insertion loss.Type: GrantFiled: July 13, 2020Date of Patent: September 12, 2023Assignee: Apple Inc.Inventors: Joonhoi Hur, Rastislav Vazny, Ronald W.

Publication number: 20230007461Abstract: An electronic device may transmit a communication request to a base station having an indication of a number of its receive branches and an indication of whether the communication request is designated as an urgent service fulfillment. The base station may delay a denial of the communication request until receiving the indication of whether the communication request is designated as using the urgent service fulfillment to reduce a likelihood of prematurely rejecting the communication request. The base station may also handover the communication request to a base station that supports the urgent service fulfillment. The base station may also be barred from transferring the user equipment to a frequency layer preferred by the base station when the communication request of the user equipment is designated as an urgent service fulfillment.Type: ApplicationFiled: August 31, 2022Publication date: January 5, 2023Inventors: Anatoliy S Ioffe, Ronald W Dimpflmaier, Alexander Sayenko, Fucheng Wang

Patent number: 10666471Abstract: Systems, methods, and devices are provided for reducing and/or eliminating impact of inter-carrier interference on wireless signals transmitted and received via off-grid radio communications (e.g., Device-to-Device (D2D) communication). The method may include using circuitry to generate a plurality of subcarriers associated with a data signal, such that the plurality of subcarriers transmit the data signal along a narrowband transmission channel. The method may involve using the circuitry to remove a null subcarrier of the plurality of subcarriers that is located at a direct current (DC) frequency. The method may also involve generating an asymmetrical frequency spectrum for a portion of the plurality of subcarriers centered about the removed null subcarrier. The method may also include transmitting the plurality of subcarriers to another electronic device via D2D communication.Type: GrantFiled: September 17, 2018Date of Patent: May 26, 2020Assignee: Apple Inc.Inventors: Lydi Smaini, Tarik Tabet, Ronald W.
