Abstract

The present invention relates to a method of automatic reception gain control in a mobile station, and an apparatus thereof. According to an exemplary embodiment of the present invention, in controlling the reception gain in the mobile station, a method of automatic reception gain control in an asynchronous mode is used when the mobile station does not ensure the synchronization with respect to a base station, and a method of automatic reception gain control in a synchronous mode is used when the mobile station ensures the synchronization with respect to the base station. Accordingly, the method of automatic gain control can be applied in combination. In addition, according to an exemplary embodiment of the present invention, when the method of automatic gain control in the synchronous mode is used in the mobile station, it can reduce the degree of gain variation that is changed in the automatic gain control by using a signal that is always transmitted from the base station at a designated time. Accordingly, the reception gain can be efficiently controlled.
