Title:
ANTENNA CONNECTION DETECTION METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2020/010915
Kind Code:
A1
Abstract:
An antenna connection detection method and apparatus, for use in detecting whether an error occurs to the connection order between communication interfaces and antenna arrays of a network side device. The method comprises: the network side device receives reference signals sent by N terminal devices by means of antenna arrays connected to multiple communication interfaces, determines N channel correlation matrixes on the basis of the reference signals sent by the N terminal devices, and then detects, on the basis of the N channel correlation matrixes and a preset channel correlation matrix, whether an error occurs to the connection order between the multiple communication interfaces and the antenna arrays, N being an integer greater than 0; and one channel correlation matrix being used for representing the correlation among transmission channels between the network side device and one terminal device.
