Small cell base station and victim terminal device detection method

A small cell base station to be mounted in a cell of a neighboring base station that is a transmission destination of a reference signal used for measuring uplink quality transmitted by a terminal apparatus, the small cell base station comprising:

• a parameter setting section that acquires a first parameter indicated to the terminal apparatus, and that sets the first parameter as a parameter of the small cell base station, the first parameter indicating transmission timing at which the terminal apparatus is to transmit the reference signal;
• a measurement section that measures interference electric power in a received signal at timing specified by the parameter set by the parameter setting section;
• a detecting section that detects the terminal apparatus connected to the neighboring base station based on the interference electric power measured by the measurement section;
• and
• an interference restriction section that restricts interference with the terminal apparatus detected by the detecting section.
