PROBLEM TO BE SOLVED: To obtain the radio communication equipment and its method in which same frequency interference power is reduced and the system capacity is improved by allowing a base station to selectively control the transmission of an omnidirectional beam or a narrow beam based on radio terminal information received from a radio terminal equipment. SOLUTION: Each of base stations 1, 2 uses a beam control section 1012 to select/control transmission of an omnidirectional beam or a narrow beam based on radio terminal information of an opposite party such as same frequency channel interference, mobile speed and in-cell traffic according to an arrived radio wave received by a plurality of antenna elements 40a-40p of an antenna array 40 prior to the transmission and uses a desired beam so as to conduct communication. Thus, Each advantage of the omnidirectional beam and the narrow beam is utilized for beam assignment, and the same frequency interference power is reduced more than the conventional communication method with the omnidirectional beam only and the radio communication equipment and the method whose system capacity is improved are obtained. |
