    Abstract: A radio base station includes multiple antennas associated with a cell. Multiple mobile radios are selected to receive transmissions over a shared radio channel during a predetermined time interval. Information is transmitted over the shared radio channel to multiple mobile radios in the cell during the predetermined time interval using multiple antenna beams. As a result, interference from the transmission appears as white additive Gaussian noise in time and in space in the cell. A "flashlight effect" caused by a single beam transmission over the shared channel during a predetermined time interval that would normally detrimentally impact mobile channel quality detection is avoided. Other methods for avoiding the flashlight effect are described. ® KIPO & WIPO 2007

    Abstract translation: 无线电基站包括与小区相关联的多个天线。 多个移动无线电被选择以在预定的时间间隔期间通过共享无线电信道接收传输。 信息通过共享无线电信道在预定时间间隔内使用多个天线波束在小区中的多个移动无线电发射。 结果,来自传输的干扰在时间和空间中表现为白色加性高斯噪声。 避免了在通常不利地影响移动信道质量检测的预定时间间隔期间通过共享信道上的单个波束传输引起的“手电筒效应”。 描述了避免手电筒效应的其他方法。 ®KIPO&WIPO 2007
