Optimal Content Placement for Offloading in Cache-enabled Heterogeneous Wireless Networks
Dong Liu, Chenyang Yang
Caching at base stations (BSs) is a promising way to offload traffic and eliminate backhaul bottleneck in heterogeneous networks (HetNets). In this paper, we investigate the optima…
A Survey of Energy-Efficient Techniques for 5G Networks and Challenges Ahead
Stefano Buzzi, Chih-Lin I, Thierry E. Klein +3
After about a decade of intense research, spurred by both economic and operational considerations, and by environmental concerns, energy efficiency has now become a key pillar in t…
Energy-saving Pushing Based on Personal Interest and Context Information
Chuting Yao, Binqiang Chen, Chenyang Yang +1
Pushing files to users based on predicting the personal interest of each user may provide higher throughput gain than broadcasting popular files to users based on their common inte…
Cache-enabled Heterogeneous Cellular Networks: Comparison and Tradeoffs
Dong Liu, Chenyang Yang
Caching popular contents at base stations (BSs) is a promising way to unleash the potential of cellular heterogeneous networks (HetNets), where backhaul has become a bottleneck. In…
Is Massive MIMO Energy Efficient?
Wenjia Liu, Shengqian Han, Chenyang Yang
Massive multi-input multi-output (MIMO) can support high spectral efficiency (SE) with simple linear transceivers, and is expected to provide high energy efficiency (EE). In this p…
Amplitude Space Sharing among the Macro-Cell and Small-Cell Users
Yafei Tian, Songtao Lu, Chenyang Yang
The crushing demand for wireless data services will soon exceed the capability of the current homogeneous cellular architecture. An emerging solution is to overlay small-cell netwo…
