TECHNOLOGY FOCUS

Available spectrum for mobile communication is limited and the ever-growing mobile broadband traffic demand cannot be served by enhancing existing LTE macro networks only (see course LTE Advanced). LTE small cell deployment is thus seen as an essential mean to provide high capacity for very densely populated outdoor and indoor areas. This training course provides the technology background when deploying LTE small cells. All small cell related functions defined in the very latest 3GPP releases are presented including eICIC, CoMP, Carrier Aggregation, Dual Connectivity, Dynamic TDD, License Assisted Access (LTE-Unlicensed) and LTE / WLAN Radio Level Aggregation and Integration. 

COURSE CONTENTS

After a short review of LTE and LTE-Advanced, small cell scenarios and deployment options will be discussed as well as different architectures to realize such heterogeneous networks. Advanced technologies such as Enhanced Inter-Cell Interference Coordination (eICIC), Inter-site Carrier Aggregation, Coordinated Multi-point Transmission (CoMP), Enhanced Interference Management and Traffic Adaption (eIMTA) or Dual Connectivity also depend on the architecture and the level of coordination between macro and small cells. Novel architectures include Cloud RANs with CPRI based fronthaul, networks with central Radio Resource Management and/or central Control Plane termination using Dual Connectivity. Yet another aspect of the training course are Home Base Stations (Femto-cells) and Self-Organizing Networks functions that are beneficial for small cell operation. For dense and ultra-dense small cell deployments with inherent large traffic variations, on/off switching becomes more important for energy saving and interference reduction.
