Abstract

A reference signal specific to each base station device and a reference signal specific to each mobile station device are not mixed within one OFDM symbol of a resource block, and OFDM symbols including the reference signal specific to each mobile station device are arranged at regular intervals on a time axis. By using such a signal arrangement pattern, it is possible to overcome the problems in Non-Patent Document 1 mentioned above caused by mixing a reference signal specific to each base station device and a reference signal specific to each mobile station device in one OFDM symbol. Thus, it becomes possible to prevent the reference signal specific to each base station device and the reference signal specific to each mobile station device from being mixed within one OFDM symbol of a resource block.
