摘要： Embodiments of the disclosure relate to reducing power consumption in a remote unit of a wireless distribution system (WDS) for intermodulation product suppression. Intermodulation products generated by a power amplifier circuit can leak from a downlink signal path into an uplink signal path to degrade sensitivity of the uplink signal path in a remote unit. In this regard, the remote unit is configured to measure a power of the leaked intermodulation products and enables a selected number of power amplifiers in the power amplifier circuit for reducing the measured power of the leaked intermodulation products to a predetermined threshold. By enabling only the selected number of power amplifiers based on the measured power of the leaked intermodulation products, it is possible to avoid enabling an excessive number of power amplifiers in the power amplifier circuit, thus helping to reduce power consumption for intermodulation product suppression.

摘要： Methods and systems for reducing leaked downlink interference signals in a remote unit uplink path(s) in a distributed antenna system (DAS) are provided. In a remote antenna unit (RAU) disclosed herein, a downlink interference signal may be leaked from a downlink path to an uplink path in the RAU. In this regard, an adjustment circuit is provided in the downlink path of the RAU to suppress the downlink interference signal. A control system is provided in the DAS to monitor the leaked downlink interference signal and control the adjustment circuit in the RAU to minimize the leaked downlink interference signal in the uplink path. By providing the adjustment circuit in the RAU and the control system in the DAS to minimize the leaked downlink interference signal in the uplink path, it is possible to reduce interferences between downlink and uplink communications signals without increasing costs of the RAU.
摘要翻译：提供了用于减少分布式天线系统（DAS）中的远程单元上行链路路径中泄漏的下行链路干扰信号的方法和系统。在本文公开的远程天线单元（RAU）中，下行链路干扰信号可以从RAU的下行链路路径泄漏到上行链路路径。在这方面，在RAU的下行链路路径中设置调整电路，以抑制下行链路干扰信号。在DAS中提供控制系统来监视泄漏的下行链路干扰信号，并控制RAU中的调整电路以最小化上行链路路径中泄漏的下行链路干扰信号。通过在RAAS中提供调整电路和DAS中的控制系统以最小化上行链路路径中泄漏的下行链路干扰信号，可以减少下行链路和上行链路通信信号之间的干扰，而不增加RAU的成本。

摘要： Monitoring non-supported wireless spectrum within a coverage area of a distributed antenna system (DAS) in which a listening module connected to a remote unit of the DAS monitors non-supported wireless frequencies (i.e., frequencies that are outside the frequency ranges supported by the downlink and uplink signals of the DAS), via one or more antennas. The listening module also transmits the wireless frequencies to a monitoring module connected to head-end equipment (HEE) of the DAS. In that manner, a monitoring module can use an existing DAS infrastructure to monitor non-supported portions of the wireless spectrum at remote locations. In addition to avoiding the need to run a parallel DAS infrastructure, the disclosed arrangements are also useful in shared spectrum environments and other environments where efficient spectrum utilization is desired.
