Downlink Coordinated Multi-Point with Overhead Modeling in Heterogeneous Cellular Networks
Ping Xia, Chun-Hung Liu, Jeffrey G. Andrews
Coordinated multi-point (CoMP) communication is attractive for heterogeneous cellular networks (HCNs) for interference reduction. However, previous approaches to CoMP face two majo…
Heterogeneous Cellular Networks with Flexible Cell Association: A Comprehensive Downlink SINR Analysis
Han-Shin Jo, Young Jin Sang, Ping Xia +1
In this paper we develop a tractable framework for SINR analysis in downlink heterogeneous cellular networks (HCNs) with flexible cell association policies. The HCN is modeled as a…
Fundamentals of Inter-cell Overhead Signaling in Heterogeneous Cellular Networks
Ping Xia, Han-Shin Jo, Jeffrey G. Andrews
Heterogeneous base stations (e.g. picocells, microcells, femtocells and distributed antennas) will become increasingly essential for cellular network capacity and coverage. Up unti…
Open, Closed, and Shared Access Femtocells in the Downlink
Han-Shin Jo, Ping Xia, Jeffrey G. Andrews
A fundamental choice in femtocell deployments is the set of users which are allowed to access each femtocell. Closed access restricts the set to specifically registered users, whil…
Open vs Closed Access Femtocells in the Uplink
Ping Xia, Vikram Chandrasekhar, Jeffrey G. Andrews
Femtocells are assuming an increasingly important role in the coverage and capacity of cellular networks. In contrast to existing cellular systems, femtocells are end-user deployed…
