Abstract

本发明实施例提供了一种用户设备UE和信道质量测量方法，涉及多天线技术领域，该UE包括：基带芯片、至少两根发射天线以及与至少两根发射天线电性相连的控制器；其中，控制器，用于获取信号发送策略，信号发送策略为UE与基站预先约定的策略，信号发送策略包括按照预设顺序通过至少两根发射天线中的n根发射天线发送信道探测参考信号SRS至基站；控制器，还用于按照预设顺序从至少两根发射天线中依次选择n根发射天线；基带芯片，用于通过控制器选择的n根发射天线依次发送SRS信号至基站，基站根据接收到的各个SRS信号进行信道质量测量。解决了现有技术中由于UE中的多根发射天线并行发送SRS信号，因此每根发射天线的发射功率较低的问题。
