Abstract
A time period between transmission of a synchronization signal and the next transmission thereof may become undesirably longer depending on a usage state of an unlicensed band and a terminal apparatus requires a long time to measure receive power of signals from a plurality of base station apparatuses that perform communication in the unlicensed band. A base station apparatus that communicates with a terminal apparatus in a second frequency band different from a first frequency band includes: a DL signal generator that generates a signal to be transmitted to the terminal apparatus; a radio transmitter that transmits the signal; and a connected terminal manager that receives subframe information to be transmitted to the terminal apparatus from another base station apparatus that communicates with the terminal apparatus in the first frequency band. The radio transmitter transmits the signal with at least one subframe included in the subframe information.
