    • Embodiments of the present invention provide a pilot sending method and an apparatus, which relate to the communication field and can save network resources. The solution is: performing spreading on at least two signature sequences by using a spreading code, where each signature sequence of the at least two signature sequences corresponds to at least one user equipment (UE), and is used as a dedicated pilot of at least one data stream of the at least one UE, and the dedicated pilot is used by the UE to perform precoding matrix estimation; and performing precoding on the spread signature sequences, and sending the precoded spread signature sequences to the UE. The embodiments of the present invention are applicable to the sending of pilots in MU-MIMO.

    • A lens driving device has a stationary part including an iron shell, a movable part including a lens holder for holding a lens therein, and a driving part for moving the movable part relative to the stationary part. The driving part includes a plurality of magnets fixed to the iron shell, and at least one coil fixed to the lens holder. The magnets are divided into at least two layers stacked in the direction of the optical axis of the lens and a plurality of groups along the circumferential direction of the lens. Each magnet is polarized in the radial direction of the lens. The polarities of two adjacent stacked magnetic poles in the same group are opposite to each other so as to cooperatively form a magnetic circuit in a plane parallel to the optical axis direction. The coil includes an axis about which the coil is wound. The coil axis is perpendicular to the optical axis. The coil has an upper part facing one layer of magnets and a lower part facing the other layer of magnets.
    • 透镜驱动装置具有包括铁壳的固定部分,包括用于在其中保持透镜的透镜保持器的可动部分和用于相对于静止部分移动可动部分的驱动部分。 驱动部包括固定在铁壳上的多个磁体和固定在透镜架上的至少一个线圈。 磁体被分成在透镜的光轴方向上堆叠的至少两层,沿着透镜的圆周方向分成多个组。 每个磁体在透镜的径向上被极化。 同一组中两个相邻层叠磁极的极性彼此相反,从而在平行于光轴方向的平面中协同地形成磁路。 线圈包括卷绕线圈的轴线。 线圈轴线垂直于光轴。 线圈具有面向一层磁体的上部和面向另一层磁体的下部。
