-Box Optimization for Green Cloud-RAN via Network Adaptation
Fan Zhang, Qiong Wu, Hao Wang +1
In this paper, we propose a reformulation for the Mixed Integer Programming (MIP) problem into an exact and continuous model through using the -box technique to recast the…
Enhanced Group Sparse Beamforming for Green Cloud-RAN: A Random Matrix Approach
Yuanming Shi, Jun Zhang, Wei Chen +1
Group sparse beamforming is a general framework to minimize the network power consumption for cloud radio access networks (Cloud-RANs), which, however, suffers high computational c…
Generalized Sparse and Low-Rank Optimization for Ultra-Dense Networks
Yuanming Shi, Jun Zhang, Wei Chen +1
Ultra-dense network (UDN) is a promising technology to further evolve wireless networks and meet the diverse performance requirements of 5G networks. With abundant access points, e…
Layered Group Sparse Beamforming for Cache-Enabled Green Wireless Networks
Xi Peng, Yuanming Shi, Jun Zhang +1
The exponential growth of mobile data traffic is driving the deployment of dense wireless networks, which will not only impose heavy backhaul burdens, but also generate considerabl…
