Abstract
A base station and a radio communication system obtain a desired communication quality by suppressing an influence of interference between a cell in an upper-airspace area and a cell in a terrestrial area when a terminal apparatus is used in the upper-airspace area. The base station is provided with an antenna, a radio communication section for forming a first cell and a second cell above the first cell and performs radio communication via the antenna to and from terminal apparatuses in the different cells. A radio resource of the same frequency band is assigned to communicate with the terminal apparatus in either the first cell or the second cell in a same time period. When the radio resource is assigned to the terminal apparatus in the second cell, a transmission power control reduces transmission power that is applied to the terminal apparatus to which the radio resource is assigned.
