Abstract:
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.

Claim (Index 1):
A remote unit in a wireless communications system, comprising:\n a coupling device coupled to a downlink path and an uplink path, the coupling device configured to:\n receive a downlink signal from the downlink path and provide the downlink signal to an antenna, wherein the downlink signal comprises at least one downlink communications signal and at least one downlink interference signal; and \n provide an uplink signal to the uplink path, wherein the uplink signal comprises an uplink communications signal received from the antenna and the at least one downlink interference signal leaked from the downlink path to the uplink path; \n an adjustment circuit comprising a local controller communicatively coupled to a process controller in an interference reduction control system, the local controller configured to suppress the at least one downlink interference signal in the downlink signal based on an adjustment control signal received from the interference reduction control system that is communicatively coupled to the adjustment circuit; and a first downlink signal amplifier and a second downlink signal amplifier disposed according to a serial arrangement in the downlink path before the coupling device, wherein the adjustment circuit comprises an adjustable matching circuit disposed between the first downlink signal amplifier and the second downlink signal amplifier.
