Abstract

User equipment communicates with a base station apparatus, and the user equipment includes a transmitter that performs transmission to the base 5 station apparatus while performing beam forming using an antenna with directivity; and a controller that controls maximum transmission power of the transmission with the beam forming based on gain of the antenna. 10 FIG.6
