TRANSMITTING METHOD, BASE STATION DEVICE USING THE SAME, RECEIVING METHOD, AND TERMINAL APPARATUS USING THE SAME

摘要

PROBLEM TO BE SOLVED: To keep a waiting state in a terminal apparatus even when antenna directivity in announcing an alert signal is changed. SOLUTION: A signal processing part 18 performs a signal processing required for an exchange processing by an adaptive array antenna. An antenna 14 for a base station performs the exchange processing concerning a radio frequency signal. A changeover part 26 externally includes an interface so as to receive an indication whether an antenna pattern in announcing the alert signal is made to be directional or nondirectional. A threshold generating part 28 sets a waiting zone holding level, based on the indication received by the changeover part 26, and generates a directivity transmission flag. An information generating part 30 sets the waiting zone holding level and the directivity transmission flag, which are set by the threshold generating part 28, in the alert signal.
