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。
