Abstract: A method and apparatus are provided for nulling a radio frequency (RF) beam for a high-altitude platform (HAP). A transmitter generates an RF signal. A primary antenna system generates an RF beam based on the RF signal. One or more processors determine a result indicating whether to modify the RF beam. When the result indicates to modify the RF beam, a detachable nulling subassembly generates nulling signals based on the RF signal to modify the RF beam generated by the primary antenna system.

Abstract: The technology relates to simulating a dynamic hybrid network. A method for simulating a dynamic hybrid network includes modeling a transmission supply of a mesh network of moving stations on aerial vehicles in flight at each time step in a time series, modeling capacity demand as a function of user distribution data and user behavior data, and computing an aggregate network metric for the dynamic hybrid network including throughput. A method for optimizing throughput of a dynamic hybrid network includes modeling a dynamic hybrid network, including a transmission supply of a mesh network of moving stations, modeling capacity demand as a function of user distribution data and user behavior data, and computing an aggregate network metric; then providing feedback to a controller and causing a change to a station in the network to increase throughput.

Abstract: A base station, a communication system and a time synchronization method between base stations are provided, which are capable of performing a time synchronization with another base station using a downlink signal of the other base station cell in which the own cell is located, without stopping transmission of the own base station even during operation. A base station receives a downlink signal that includes a downlink signal including a synchronization signal transmitted from the other base station and a downlink wraparound signal transmitted from own base station, removes an interference of the wraparound signal from the downlink received signal, with respect to a predetermined subframe in which the downlink wraparound signal from own base station interferes with the synchronization signal of the base station, among subframes of the downlink signal including the synchronization signal of the base station, performs a time synchronization processing with the base station by detecting a synchronization signal timing of the base station based on the downlink received signal from which the interference of wraparound signal is removed.

Abstract: In a mobile communication system using a mobile-type radio relay apparatus that forms a plurality of cells toward the ground or the sea while moving in an upper airspace, a deterioration in communication quality, which is caused by a Doppler shift of a reception signal due to a relative movement of a radio relay apparatus with respect to a terminal apparatus of each of a plurality of cells or a feeder station on the ground or on the sea, is suppressed. The communication system comprises a mobile-type radio relay apparatus that is disposed movably by flying in an upper airspace, forms a plurality of cells from an antenna at a predetermined altitude toward the ground or the sea, and performs a radio communication with a terminal apparatus located in each of the plurality of cells. The communication system comprises an estimation section for estimating a Doppler shift in at least one of a radio communication of a service link between the terminal apparatus located in the cell and the radio relay apparatus and a radio communication of a feeder link between the radio relay apparatus and a feeder station on the ground or on the sea, and a correction section for correcting a frequency of the at least one radio communication based on an estimation result of the Doppler shift.
