摘要：
A method includes transmitting reference signals to user equipment from an active antenna array system including a multiple of antennas arrayed in at least a vertical direction. The active antenna array system is configured to perform the transmitting of the reference signals using multiple vertical beams having vertical patterns designed to provide desired vertical patterns after codebook feedback from a codebook is applied on transmissions from logical ports of the antenna array. The method includes receiving codebook feedback from the user equipment in response to transmitting the reference signals. The method includes transmitting information to the user equipment at least by applying selected entries of the codebook corresponding to the codebook feedback to the logical ports of the antenna array, wherein application of the selected entries causes the active antenna array system to perform transmitting information using multiple beams having the desired vertical patterns. Apparatus and program products are disclosed.
摘要（中）：
一种方法包括从包括在至少垂直方向上排列的多个天线的有源天线阵列系统向用户设备发射参考信号。 有源天线阵列系统被配置为使用具有设计成在从码本的码本反馈之后提供期望的垂直图案的垂直图案的多个垂直波束来执行参考信号的发送，所述垂直图案被应用于来自天线阵列的逻辑端口的传输。 该方法包括响应于发送参考信号从用户设备接收码本反馈。 该方法包括至少通过将对应于码本反馈的码本的选定条目应用于天线阵列的逻辑端口来向用户设备发送信息，其中应用所选择的条目使得有源天线阵列系统使用多个 光束具有所需的垂直图案。 公开了装置和程序产品。
