Abstract
A mobile station includes: a baseband processor; and an RF front-end module connected to the baseband processor and including a plurality of antenna modules and a controller. The plurality of antenna modules each include an antenna element and a variable phase shifter connected to the antenna element. The baseband processor is configured to output a beam control signal indicating a direction of an antenna beam formed by the plurality of antenna elements. The controller is configured to receive the beam control signal from the baseband processor, determine a phase control amount for each variable phase shifter on the basis of the beam control signal, and control each variable phase shifter on the basis of the determined phase control amount.
