ABSTRACT:
A control method of the direction of directivity of a base station antenna in a mobile communication system which uses a variable directivity antenna at the base station. The direction of directivity is controlled to continuously change such that signal reception level at each mobile station exceeds a prescribed value during the time interval from the beginning of the first slot to the end of the (n+1)th slot of any continuous n+1 (n being a natural number) slots on at least one time-division-multiplexed channel.
