Abstract

本发明实施例提供一种天线校准方法、装置及基站，所述方法包括：基站确定静默时隙的位置和时长，其中，所述静默时隙内所述基站和终端均不收发信号；所述基站在所述静默时隙内进行天线校准。采用本发明实施例提供的天线校准方法、装置及基站，可以防止基站在进行天线校准的过程中接收通道中的校准序列受到外部信号的干扰，保证天线校准的精度。

Embodiments of the present invention provide an antenna calibration method, device, and base station. The method includes: the base station determines the location and duration of a silent time slot, wherein neither the base station nor the terminal sends and receives signals in the silent time slot; the The base station performs antenna calibration during the silent time slot. By using the antenna calibration method, device and base station provided by the embodiments of the present invention, the calibration sequence in the receiving channel of the base station can be prevented from being interfered by external signals during the antenna calibration process, and the accuracy of the antenna calibration can be ensured.
