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

Effects of range expansion and interference coordination on capacity and fairness in heterogeneous networks
Sayandev Mukherjee,Ismail Guvenc +1 more
TL;DR: Analytical models for base station and user locations in a macro network with pico-cell overlay are considered and closed-form expressions for the distribution of the signal to interference plus noise ratio (SINR) and spectral efficiencies (SEs) of UEs associated with macro- and pICO-cells are derived.

Abdel-karim Ajami,Hassan Artail +1 more
TL;DR: This analysis quantifies both single-user and multi-user operation modes of the IEEE802.11ax Wi-Fi standard and shows that LTE-U or LAA can be a good neighbor for IEEE 802.11AX for different traffic types.

Multichannel Analysis of Cell Range Expansion and Resource Partitioning in Two-Tier Heterogeneous Cellular Networks
TL;DR: An analytical framework is developed to evaluate the performance gain due to CRE further supported by resource partitioning in two-tier (macro-pico) networks with multichannel downlinks, e.g., those based on orthogonal frequency division multiple access (OFDMA).

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.
