10.The Steering committee meeting took place from 11:45 to 12:45 on March 27th, 2015.

11. Concluding Remarks
We had four interesting talks about five generation (5G) mobile communication systems which have been attracting much attention as one of hot topics. Propagation characteristics using quasi-millimeter frequency bands, analog-digital hybrid beamforming method for massive MIMO, configuration of channel sounder using massive array, and calibration method for massive MIMO have been presented by four presenters.
Moreover, fruitful discussion has been held in which present and future works were provided. We had valuable discussion and obtained meaningful information about techniques on 5G systems.
