  • Publication number: 20210160806
    Abstract: Embodiments of this application provide a method and an apparatus for reducing co-channel interference, and a base station. The method includes: receiving, by a relay eNodeB ReNB, a propagation delay sent by a donor eNodeB DeNB, where the propagation delay is a delay of propagation between the DeNB and the ReNB; and adjusting, based on the propagation delay, timing parameters for sending uplink data and receiving downlink data by the ReNB, where the timing parameters are delays of the ReNB relative to the DeNB. The DeNB is used as a reference for the propagation delay between the DeNB and the ReNB, to delay timing of receiving the downlink data by the ReNB; and advance timing of sending the uplink data by the ReNB.

    Abstract: A three-dimensional (3D) memory device and a manufacturing method thereof are provided. The method includes the following steps. An alternating dielectric stack is formed on a substrate. An opening is formed penetrating the alternating dielectric stack in a thickness direction of the substrate. A blocking layer is formed on a sidewall of the opening. A trapping layer is formed in the opening, and the trapping layer is formed on the blocking layer. The trapping layer includes a lower portion and an upper portion disposed above the lower portion. A thickness of the upper portion in a horizontal direction is greater than a thickness of the lower portion in the horizontal direction.

  • Publication number: 20210075311
    Abstract: For grid-connected power converter control, a method estimates a d-axis grid voltage from a d-axis reference current modified with a d-axis current and a q-axis current modified with a filter inductive reactance. The method generates a q-axis current error from a direct current (DC) voltage input and a DC bus voltage. The method estimates an observer q-axis grid voltage from a q-axis voltage output. The q-axis grid voltage observer estimates the q-axis grid voltage in a direct/quadrature (dq) reference frame equivalent to an ABC to DQ reference frame transform. The method determines a d-axis voltage output as a function of a d-axis current error and a q-axis current modified with a filter inductive reactance. The method determines a q-axis voltage output as a sum of the q-axis current controller output and the observer q-axis grid voltage.
