| 摘要 |
To provide a radio base station apparatus, mobile terminal device and wireless communication method for enabling the SRS to be used efficiently in an LTE-A system, a wireless communication method of the invention is characterized in that a radio base station apparatus performs OFDM modulation on a transmission signal including transmission information on sounding reference signals for each transmission antenna, and transmits the OFDM-modulated transmission signal, and that a mobile terminal device receives the signal including the transmission information, controls a transmission aspect of the sounding reference signals for each transmission antenna based on the transmission information, and transmits the sounding reference signals in the transmission aspect for each transmission antenna.
