Abstract

本发明公开了一种探测参考信号的发送方法、基站和用户设备。该方法包括：基站生成用于上行传输的下行控制信息，该下行控制信息包括指示用户设备是否发送非周期的探测周期信号、以及在发送该非周期的探测参考信号时，所使用的资源的指示信息；并且利用该下行控制信息中新数据指示器的比特和非周期的探测参考信号请求的比特来承载该指示信息；向用户设备发送该下行控制信息，以使该用户设备根据该下行控制信息中包含的指示信息进行非周期的探测参考信号的发送。通过本发明实施例，基站可有效地利用用于上行传输的下行控制信息，如DCI format0或DCI format4中的新数据指示器（NDI）的比特，又可增加供选择的资源，减少非周期的探测参考信号（SRS）发生碰撞的可能性。
