用于在分布式天线系统中并且通过分布式天线系统进行的性能优化的系统和方法
Abstract:
一种用于操作DAS的方法，包括：提供能够被操作用以发送和接收无线无线电信号的一组数字远程单元(远程装置)。该组远程装置中的每个远程装置与地理区域相关联。方法还包括：提供能够被操作用以与该组远程装置通信的数字接入单元(主机)；接收该组远程装置中的一个或更多个远程装置处的上行链路信号；以及监视地理区域中的火车活动。该方法还包括：响应于确定所监视的火车活动的增加而增大与该组远程装置中的一个远程装置相关联的增益系数；响应于确定所监视的火车活动的减少而减小与该组远程装置中的另一个远程装置相关联的增益系数；以及向主机传送与该组远程装置中的所述一个远程装置以及该组远程装置中的所述另一个远程装置相关联的经比例缩放的上行链路信号。
Abstract(English):

A method for operating a Distributed Antenna System (DAS) includes providing a plurality of Digital Remote Units (DRUs), each configured to send and receive wireless radio signals and providing a plurality of inter-connected Digital Access Units (DAUs), each configured to communicate with at least one of the plurality of DRUs via optical signals and each being coupled to at least one sector of a base station. The method also includes providing a plurality of sensors operable to detect activity at each of the plurality of DRUs, turning off a DRU downlink signal at one of the plurality of DRUs in response to an output from one of the plurality of sensors, and turning on a DRU downlink signal at another of the plurality of DRUs in response to an output from another of the plurality of sensors.
