Abstract

本发明提供了进行下行信道质量监测的方法以及装置。第一网络设备具有第一多个天线。该方法包括：在一个第一无线子帧内的第一多个时频资源上，第一网络设备分别经由第一多个天线发送第一多个信道状态信息参考信号，其中，第一多个时频资源共享第一无线子帧内的一个时间段。由于用于传输信道状态信息参考信号的多个时频资源共享该时间段，即多个信道状态信息参考信号共享一个时间段，例如共享一个正交频分复用符号，因此，即使基站从多天线发送信道状态信息参考信号变为单天线发送信道状态信息参考信号，各OFDM符号的功率都不会发生变化，从而使得基站侧的发射功率最大化，进而提高用户终端设备接收信道状态信息参考信号的性能。
