Abstract
When there is a movement or attitude change of an upper-airspace staying type communication relay apparatus, it is suppressed of an increase in control signals and disconnection of communication with a terminal apparatus in a cell configuring a service area, and it is reduced of a circuit scale and power consumption of a base-station processing section. The base-station processing section of the communication relay apparatus performs, with respect to a radio resource part for control communication by which a communication is performed with plural terminal apparatuses located in a cell via a single or plural beams for control among downlink and uplink radio resources used for service links, a footprint fixation control for performing a precoding and a postcoding so as to fix a position of a footprint corresponding to the beam for control, based on information on at least one of a position and attitude of the communication relay apparatus, and does not perform the footprint fixation control on the basis of the information on the at least one of the position and attitude, with respect to downlink and uplink radio resource parts other than the radio resource part for control communication.
