description It is suppressed of a deterioration of a communication quality of a service link (SL), which is caused by an increase of signal attenuation in a propagation path of a feeder link (FL) between an aerial-staying type communication relay apparatus and a gateway (GW) station. A relay communication station of the communication relay apparatus comprises a FL communication section that performs a feeder-link radio communication with each of a first gateway station and a second gateway station corresponding to a first cell and a second cell which are adjacent to each other, a SL communication section that performs a radio communication with a terminal apparatus in each SL of the first cell and the second cell, and a control section that controls the SL communication section so that a shape of the second cell is changed to include a part or a whole of the first cell, when a radio communication quality in the FL propagation path with the first gateway station corresponding to the first cell is deteriorated or when the deterioration of the radio communication quality is predicted.
