Review of 5G C-RAN Resource Allocation

Distributed Resource Allocation in 5G Cellular Networks

The fifth generation (5G) cellular networks are expected to provide wide variety of high rate (i.e., 300 Mbps and 60 Mbps in downlink and uplink, respectively, in 95 percent of locations and time [1]) multimedia services. The 5G communication platform is seen as a global unified standard with seamless connectivity among existing standards, e.g., High Speed Packet Access (HSPA), Long Term Evolut...

Evolving to an Open C-RAN Architecture for 5G

Energy Efficient Joint Resource Allocation for Multi-cell C-RAN System

In this paper, we propose a joint resource allocation algorithm for energy efficiency (EE) of a cloud radio access network (C-RAN). To tackle the joint optimization problem, we utilize a successive convex approximation (SCA) based joint antenna selection and power allocation (JASPA) algorithm. In addition, we propose an improved multi-candidate remote radio heads (RRHs) user association (MCRUA)...

Joint Energy Minimization and Resource Allocation in C-RAN with Mobile Cloud

Cloud radio access network (C-RAN) has emerged as a potential candidate of the next generation access network technology to address the increasing mobile traffic, while mobile cloud computing (MCC) offers a prospective solution to the resource-limited mobile user in executing computation intensive tasks. Taking full advantages of above two cloud-based techniques, C-RAN with MCC systems are pres...

Joint CoMP-Cell Selection and Resource Allocation with Fronthaul-Constrained C-RAN

Cloud-based Radio Access Network (C-RAN) is a promising architecture for future cellular networks, in which Baseband Units (BBUs) are placed at a centralized location, with capacity-constrained fronthaul connected to multiple distributed Remote Radio Heads (RRHs) that are far away from the BBUs. The centralization of signal processing enables the flexibility for coordinated multi-point transmis...
