Abstract
A master station apparatus modulates downlink digital control data that includes at least a synchronization signal and a control signal, adds resource element information to the modulated control data, and composites downlink digital frequency-domain user data that has not been modulated and data originating from the modulated control data to which the resource element information has been added. A slave station apparatus converts a received optical signal into an electrical signal, separates, from the electrical signal, the frequency-domain user data and the data originating from the modulated control data, modulates the frequency-domain user data, adds resource element information to the modulated user data, and transmits time-domain composite data including a component originating from the modulated user data and a component originating from the modulated control data by radio waves.
