Abstract
Provided is an aerial-floating type communication relay apparatus capable of reducing a size and suppressing a movement of a cell footprint. The communication relay apparatus comprises an array antenna that has plural antenna elements forming a cell for performing a radio communication of a service link with a terminal apparatus, an information acquisition section that acquires information on at least one of a position and an attitude of the communication relay apparatus, and a control section that controls phases and amplitudes of plural transmission/reception signals transmitted/received via each of the plural antenna elements of the array antenna so as to fix the position of the cell footprint, based on the information on at least one of the position and the attitude of the communication relay apparatus.
