摘要

PROBLEM TO BE SOLVED: To provide a base station device, a mobile station device, a communication system and a communication method which can efficiently reduce or suppress interference between cells in a wireless communication system constituting a heterogeneous network.

SOLUTION: In a wireless communication system, a first base station device and a mobile station device perform intercommunication. The first base station device notifies the mobile station device of the cancellation of a reference signal which is transmitted from a second base station device different from the first base station device and is unique to the second base station device.
