    • An antenna apparatus that can increase capacity in a wireless communication system is disclosed. The antenna operates in conjunction with a station and comprises a plurality of antenna elements, each coupled to a respective weight control component to provide a weight to the signal transmitted from (or received by) each element. The weight for each antenna element is adjusted to achieve optimum reception during, for example, an idle mode when a pilot signal is received. The antenna array creates a beam former for signals to be transmitted from the mobile station, and a directional receiving array to more optimally detect and receive signals transmitted from the base station. By directionally receiving and transmitting signals, multipath fading and intercell interference are greatly reduced. The weights are adjusted in a coarse and a fine mode. In the coarse mode all the weight control components are jointly adjusted or changed so that the antenna beam scans through a predetermined sector of a circle until a signal quality metric of the received signal is optimized. The coarse adjustment mode is followed by a fine adjustment mode during which the weights of are independently adjusted to further optimize the signal quality metric.
    • 公开了一种可以增加无线通信系统中的容量的天线装置。 天线与站一起工作,并且包括多个天线元件,每个天线元件耦合到相应的加权控制部件,以向从每个元件(或由每个元件接收)发送的信号提供权重。 当接收到导频信号时,调整每个天线元件的权重以在例如空闲模式期间实现最佳接收。 天线阵列产生用于要从移动台发送的信号的波束形成器,以及用于更好地检测和接收从基站发送的信号的定向接收阵列。 通过定向接收和发送信号,大大减少了多径衰落和小区间干扰。 重量在粗调和精细模式下进行调整。 在粗略模式中,所有的权重控制分量被共同调整或改变,使得天线波束扫过预定的圆圈,直到接收信号的信号质量度量被优化。 粗调模式之后是精细调整模式,其中独立调整权重以进一步优化信号质量度量。
