Smoothed Lp-Minimization for Green Cloud-RAN with User Admission Control
Yuanming Shi, Jinkun Cheng, Jun Zhang +3
The cloud radio access network (Cloud-RAN) has recently been proposed as one cost-effective and energy-efficient technique for 5G wireless networks. By moving the signal processing…
Robust Group Sparse Beamforming for Multicast Green Cloud-RAN with Imperfect CSI
Yuanming Shi, Jun Zhang, Khaled B. Letaief
In this paper, we investigate the network power minimization problem for the multicast cloud radio access network (Cloud-RAN) with imperfect channel state information (CSI). The ke…
A Lyapunov Optimization Approach for Green Cellular Networks with Hybrid Energy Supplies
Yuyi Mao, Jun Zhang, Khaled B. Letaief
Powering cellular networks with renewable energy sources via energy harvesting (EH) has recently been proposed as a promising solution for green networking. However, with intermitt…
Joint Channel and Queue Aware Scheduling for Wireless Links with Multiple Fading States
Juan Liu, Wei Chen, Khaled B. Letaief
In this work, we address the delay optimal scheduling problem for wireless transmission with fixed modulation over multi-state fading channels. We propose a stochastic scheduling p…
Backhaul-Aware Caching Placement for Wireless Networks
Xi Peng, Juei-Chin Shen, Jun Zhang +1
As the capacity demand of mobile applications keeps increasing, the backhaul network is becoming a bottleneck to support high quality of experience (QoE) in next-generation wireles…
Large-Scale Convex Optimization for Ultra-Dense Cloud-RAN
Yuanming Shi, Jun Zhang, Khaled B. Letaief +2
The heterogeneous cloud radio access network (Cloud-RAN) provides a revolutionary way to densify radio access networks. It enables centralized coordination and signal processing fo…
