Millimeter-Wave Evolution for 5G Cellular Networks
Kei Sakaguchi,Gia Khanh Tran,Hidekazu Shimodaira,Shinobu Nanba,Toshiaki Sakurai,Koji Takinami,Isabelle Siaud,Emilio Calvanese Strinati,Antonio Capone,Ingolf Karls,Reza Arefi,Thomas Haustein +11 more
TL;DR: In this article, the authors proposed a comprehensive architecture of cellular networks with mmWave access, where mm-wave small cell basestations and a conventional macro basestation are connected to Centralized-RAN to effectively operate the system by enabling power efficient seamless handover as well as centralized resource control including dynamic cell structuring.
Proceedings ArticleDOI
Cloud cooperated heterogeneous cellular networks
Kei Sakaguchi,Seiichi Sampei,Hidekazu Shimodaira,Roya E. Rezagah,Gia Khanh Tran,Kiyomichi Araki +5 more
TL;DR: Several numerical simulations show effectiveness of the proposed C-HetNet architecture, where 1,000 times system rate than that of current single band cellular network is achieved by using the proposed architecture.
Proceedings ArticleDOI
Dynamic cell activation and user association for green 5G heterogeneous cellular networks
TL;DR: A future C-RAN based cloud cooperated HetNet which enables global resource optimization among smallcells is considered which allows optimal user association for data offloading as well as dynamic ON/OFF of smallcell BSs in adaptation to daily data traffic.
Proceedings ArticleDOI
Outdoor millimeter-wave access for heterogeneous networks — Path loss and system performance
Richard J. Weiler,Michael Peter,Wilhelm Keusgen,Hidekazu Shimodaira,Khanh Tran Gia,Kei Sakaguchi +5 more
TL;DR: The millimeter-wave frequency bands, especially the license free band at 60 GHz, is a candidate for future broadband access links and a system level analysis was performed to evaluate the performance of a heterogeneous network using millimeterwave access links.
Proceedings ArticleDOI
Cell association method for multiband heterogeneous networks
Hidekazu Shimodaira,Gia Khanh Tran,Kiyomichi Araki,Shinobu Nanba,Takahiro Hayashi,Kei Sakaguchi,Satoshi Konishi +6 more
TL;DR: A novel cell association method based on the combinatorial optimization that achieves system rate gain twice as high as the conventional one for multiband HetNet.
