ABSTRACT:
A multi-beam cellular base station is for sending a spread spectrum signal to at least one mobile station, the base station comprising: first antenna for sending a common channel by a common beam that a directional pattern is formed previously; second antenna for sending a dedicated channel by a dedicated beam that a directional pattern is formed for each mobile station; and switching means for switching a sending time section of the common beam and a sending time section of the dedicated beam so that the sending time sections do not overlap within a time slot, the common beam and the dedicated beam are sent by same frequency.
