Challenges for beyond 5G:ultra-densification of radio access network by Fumiyuki Adachi, Ryo Takahashi, Hidenori Matsuo

“…Ultra-densification of radio access network (RAN) is a key to efficiently support the exponentially growing mobile data traffic in 5G era.Furthermore,extremely high frequency band like mmWave band was utilized to solve the bandwidth shortage problem.However,untra-dense reusing the same radio resource produced severe interference.And the mmWave link was very harsh due to frequent blockage by obstacles.Therefore a new RAN architecture needed to be introduced to realize ultra-reliable communications in such a severe radio propagation environment.An architecture of distributed MIMO based RAN was presented.Then,enhanced interference coordination (eIC) was described.Finally,the effectiveness of distributed MIMO based RAN with eIC by computer simulation was showed.…”

3D MIMO channel modeling and simulations by Xiongwen ZHAO, Mengyuan ZHANG, Rui ZHANG, Shu LI, Leke LIN

“…The existing MIMO channel simulation models are based on two-dimensional（2D）plane and can’t match with a three-dimensional（3D）radio propagation environment.A 3D MIMO channel simulation platform based on WINNER channel model was set up.After adding the vertical dimension in the model，the array patterns should be extended from 2D to 3D and 3D MIMO channel simulations were implemented.The simulation results of 3D MIMO channel parameters were validated by comparisons with the 3D measurements for an urban micro cell，good agreements could be observed.Simulation results show that the 3D channel correlation is bigger than 2D，however， its capacity has bigger improvement compared with 2D.…”
