Abstract: The present disclosure provides example line order detection methods and multi-antenna network devices. One example method includes obtaining preset antenna numbers of a target antenna group. A first uplink received signal strength sequence of each antenna channel is determined based on a first uplink reference signal sequence from a terminal. After an antenna downtilt angle of the target antenna group is adjusted from a first downtilt angle to a second downtilt angle, a second uplink received signal strength sequence of each antenna channel is determined based on a second uplink reference signal sequence from the terminal. Actual antenna numbers of the target antenna group are determined based on the first uplink received signal strength sequence and the second uplink received signal strength sequence of each antenna channel. When the preset antenna numbers are different than the actual antenna numbers, a line order is determined to be incorrect.
