10.The Steering committee meeting took place from 13:20 to 14:00 on August 4th, 2017.

11. Concluding Remarks
In the first presentation, Dr. Yamamoto explained Narrow Band - IoT which was standardized for mobile communication specifications by the 3rd Generation Partnership Project (3GPP). Next, Dr. Takeda explained non-orthogonal multiple access and grant-free access technologies which is being discussed for 5G mobile communication systems. Finally, Associate Prof. Okamoto introduced 'Low-density signature' and 'Sparse code multiple access' to realize multiple access for a large number of terminals.
A lively discussion was held with many questions about future IoT devices and technologies. We have a policy of this meeting to have enough time for discussion, the question and response time was extended by 5 minutes at each presentation.
I think it became a place of information exchange that deepened the understanding about communications technology in the IoT space, and at the same time meaningful comments from prominent professors in the mobile communication field were received.
