Abstract

The present invention is designed to make effective use of radio resources in VSEC to output a plurality of beams of varying tilt angles for sectorization in vertical directions. A radio communication method for a radio base station that outputs a plurality of beams of varying tilt angles and forms a plurality of cells that are sectorized vertically, and a user terminal that establishes wireless connection with the radio base station, provides the steps in which the radio base station acquires information about the communication capacity of each of the plurality of cells, and controls the vertical plane beam width and/or transmission power of each cell and sets the coverage area of each cell so that differences in communication capacity between the plurality of cells are reduced.
