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.

Abstract: A method includes: different window display schemes may be automatically switched based on different scenarios. Specifically, a plurality of windows to be displayed on a display are grouped based on at least one of refresh rates of the plurality of windows, a quantity of the windows, sizes of the windows, locations, and the like, and a lane for transmitting window data is allocated to each window group obtained after grouping, so that window data of each window group can be refreshed, drawn, rendered, and presented based on a refresh rate required by the window data, and there is no need to present all the windows at a highest refresh rate.
