WIRELESS COMMUNICATION SYSTEM, BASE STATION DEVICE, MOBILE STATION DEVICE, AND COMMUNICATION METHOD

摘要

A reference signal determined for each base station device and a reference signal determined for each mobile station device are not mixed in a single OFDM symbol of a resource block.  An OFDM symbol containing reference signals determined for respective mobile station devices are arranged at an identical interval on a time axis.  By using such a signal arrangement pattern, it is possible to avoid the problem caused by mixture of the reference signal determined for each base station device and the reference signal determined for each mobile station device in a single OFDM symbol, the problem being described in the non-patent Document 1.  Thus, it is possible to prevent simultaneous presence of the reference signals determined for the respective base station devices and the reference signals determined for the respective mobile station devices in a single OFDM symbol of a resource block.
