<p>Provided are a base station, a terminal deice, and a communication system provided with same, by which, when communication areas of base station devices overlap, interference to a terminal device located in the overlapped area can be reduced, and a system having superior frequency use efficiency can be configured. Femto terminals (21 to 23) or HeNBs (11 to 13) select, from among predetermined precoding vector candidates, the top several vectors in which usage in a MeNB (10) would result in the Femto terminals (21 to 23) or HeNBs (11 to 13) receiving higher interference, and notify the MeNB (10) of information regarding the selected vectors. The MeNB notified of such vectors determines that transmission using the notified vectors has a large influence (interference strength) on the Femto cells, and performs transmission using other precoding vectors.</p> |
