TLDR
System simulations results for an FTP traffic model indicate that, for a pico cell deployment with density of 4 picos per macro cell, 40% or more performance gain can be achieved when techniques enabling cell range expansion are deployed.Abstract:
This paper discusses the need and enabling mechanisms for a heterogeneous deployment model in LTE networks, where lower power nodes are deployed in a macro network. Cell range expansion, enabled through cell biasing and adaptive resource partitioning, is seen as an effective method to balance the load among the nodes in the network and to improve overall trunking efficiency. Interference cancellation receiver plays a crucial role to ensure acquisition of weak cells and reliability of control and data reception in the presence of legacy signal. System simulations results for an FTP traffic model indicate that, for a pico cell deployment with density of 4 picos per macro cell, 40% or more performance gain can be achieved when techniques enabling cell range expansion are deployed.read more

Cell Association and Interference Coordination in Heterogeneous LTE-A Cellular Networks
TL;DR: New paradigms for design and operation of heterogeneous cellular networks, focusing on cell splitting, range expansion, semi-static resource negotiation on third-party backhaul connections, and fast dynamic interference management for QoS via over-the-air signaling are described.
