Abstract

本发明实施例提供一种在室内分布系统中抑制上行底噪的方法、设备和系统，包括：增益调整设备获取共小区内远端覆盖单元的载波级上行用户功率以及所述共小区内其他远端覆盖单元的载波级上行用户功率；所述增益调整设备根据所述远端覆盖单元的载波级上行用户功率以及所述共小区内其他远端覆盖单元的载波级上行用户功率，确定所述远端覆盖单元的载波级权重因子；所述增益调整设备根据所述远端覆盖单元的载波级权重因子调整所述远端覆盖单元的载波级上行接收增益，其中，所述远端覆盖单元的载波级上行接收增益小于0。由于该载波级上行接收增益小于0，因此，可以降低合路后的上行底噪的功率，从而达到了减少合路后的上行底噪的目的。
