Activities for diffusion of 4G mobile communication systems Start to study on “technical requirements for the 4th generation mobile

communication systems (IMT-Advanced)” by ICC in Apr. 2012, toward introduction of IMT-Advanced system in Japan. The band 3.4-3.6GHz and candidate band for IMT-Advanced in Japan are to be studied.

Plan of interference study in ICC– In 3.4 -3.6 GHz, carry out desk calculation of interference between

IMT-Advanced and other existing systems or between IMT-Advanced systems, based on the standard value.

– In 3.6 - 4.2 GHz, apply the study results in 3.4 - 3.6 GHz band and carry out additional interference study if necessary.

– In the frequency range of the existing mobile service, investigate whether interference between IMT-Advanced and other existing systems is within the scope of the past ICC report.

ICC will report of study result in June 2013.
