Abstract
An antenna connection detection method and apparatus are provided, to detect whether a connection sequence between communications interfaces of a network side device and antenna elements is incorrect. The method includes that a network side device receives, by using antenna elements connected to a plurality of communications interfaces, reference signals sent by N terminal devices, where N is an integer greater than 0. Then, the network side device determines N channel correlation matrices based on the reference signals sent by the N terminal devices, and then determines, based on the N channel correlation matrices and a preset channel correlation matrix, whether a connection sequence between the plurality of communications interfaces and the antenna elements is incorrect, where one channel correlation matrix is used to represent correlation between transmission channels between the network side device and one terminal device.
