Title: ANTENNA GROUP SWITCHING METHOD AND RELATED DEVICE THEREOF
Abstract:
Disclosed in the embodiments of the present application are an antenna group switching method and related devices thereof, used for reducing the relative speed of movement in respect of a high-speed mobile station antenna group currently in an active state and a communicating party, and for improving the signal quality of the high-speed mobile station. The method in the embodiments of the present application comprises: the high-speed mobile station is equipped with a number N of antenna groups, the general arrangement of the N antenna groups being the same as the direction of forward movement of the high-speed mobile station, N being an integer greater than 1, and the high-speed mobile station only having one antenna group in an active state at one time; the high-speed mobile station acquires the speed of movement and the direction of movement of the high-speed mobile station, determines a target antenna group at a target time according to the speed of movement and the antenna group currently in an active state, the direction from the antenna group currently in an active state to the target antenna group being opposite to the direction of movement, and switches the active state of the antenna group from the antenna group currently in an active state to the target antenna group.
