Dual-Branch MRC Receivers under Spatial Interference Correlation and Nakagami Fading
Ralph Tanbourgi, Harpreet S. Dhillon, Jeffrey G. Andrews +1
Despite being ubiquitous in practice, the performance of maximal-ratio combining (MRC) in the presence of interference is not well understood. Because the interference received at…
On Association Cells in Random Heterogeneous Networks
Sarabjot Singh, Francois Baccelli, Jeffrey G. Andrews
Characterizing user to access point (AP) association strategies in heterogeneous cellular networks (HetNets) is critical for their performance analysis, as it directly influences t…
Downlink Multi-Antenna Heterogeneous Cellular Network with Load Balancing
Abhishek K. Gupta, Harpreet S. Dhillon, Sriram Vishwanath +1
We model and analyze heterogeneous cellular networks with multiple antenna BSs (multi-antenna HetNets) with K classes or tiers of base stations (BSs), which may differ in terms of…
Modeling, Analysis and Optimization of Multicast Device-to-Device Transmission
Xingqin Lin, Rapeepat Ratasuk, Amitava Ghosh +1
Multicast device-to-device (D2D) transmission is important for applications like local file transfer in commercial networks and is also a required feature in public safety networks…
Resource Optimization in Device-to-Device Cellular Systems Using Time-Frequency Hopping
Qiaoyang Ye, Mazin Al-Shalash, Constantine Caramanis +1
We develop a flexible and accurate framework for device-to-device (D2D) communication in the context of a conventional cellular network, which allows for time-frequency resources t…
A Tractable Model for Non-Coherent Joint-Transmission Base Station Cooperation
Ralph Tanbourgi, Sarabjot Singh, Jeffrey G. Andrews +1
This paper presents a tractable model for analyzing non-coherent joint transmission base station (BS) cooperation, taking into account the irregular BS deployment typically encount…
An Overview of Load Balancing in HetNets: Old Myths and Open Problems
Jeffrey G. Andrews, Sarabjot Singh, Qiaoyang Ye +2
Matching the demand for resources ("load") with the supply of resources ("capacity") is a basic problem occurring across many fields of engineering, logistics, and economics, and h…
Physical Layer Security in Downlink Multi-Antenna Cellular Networks
Giovanni Geraci, Harpreet S. Dhillon, Jeffrey G. Andrews +2
In this paper, we study physical layer security for the downlink of cellular networks, where the confidential messages transmitted to each mobile user can be eavesdropped by both (…
Fundamentals of Heterogeneous Cellular Networks with Energy Harvesting
Harpreet S. Dhillon, Ying Li, Pavan Nuggehalli +2
We develop a new tractable model for K-tier heterogeneous cellular networks (HetNets), where each base station (BS) is powered solely by a self-contained energy harvesting module.…
Effect of Spatial Interference Correlation on the Performance of Maximum Ratio Combining
Ralph Tanbourgi, Harpreet S. Dhillon, Jeffrey G. Andrews +1
While the performance of maximum ratio combining (MRC) is well understood for a single isolated link, the same is not true in the presence of interference, which is typically corre…
Downlink Rate Distribution in Heterogeneous Cellular Networks under Generalized Cell Selection
Harpreet S. Dhillon, Jeffrey G. Andrews
Considering both small-scale fading and long-term shadowing, we characterize the downlink rate distribution at a typical user equipment (UE) in a heterogeneous cellular network (He…
Secrecy Rates in the Broadcast Channel with Confidential Messages and External Eavesdroppers
Giovanni Geraci, Sarabjot Singh, Jeffrey G. Andrews +2
In this paper, we consider the broadcast channel with confidential messages and external eavesdroppers (BCCE), where a multi-antenna base station simultaneously communicates to mul…
On/Off Macrocells and Load Balancing in Heterogeneous Cellular Networks
Qiaoyang Ye, Mazin Al-Shalash, Constantine Caramanis +1
The rate distribution in heterogeneous networks (HetNets) greatly benefits from load balancing, by which mobile users are pushed onto lightly-loaded small cells despite the resulti…
Power Control for D2D Underlaid Cellular Networks: Modeling, Algorithms and Analysis
Namyoon Lee, Xingqin Lin, Jeffrey G. Andrews +1
This paper considers a device-to-device (D2D) underlaid cellular network where an uplink cellular user communicates with the base station while multiple direct D2D links share the…
Spectrum Sharing for Device-to-Device Communication in Cellular Networks
Xingqin Lin, Jeffrey G. Andrews, Amitava Ghosh
This paper addresses two fundamental and interrelated issues in device-to-device (D2D) enhanced cellular networks. The first issue is how D2D users should access spectrum, and we c…
Joint Resource Partitioning and Offloading in Heterogeneous Cellular Networks
Sarabjot Singh, Jeffrey G. Andrews
In heterogeneous cellular networks (HCNs), it is desirable to offload mobile users to small cells, which are typically significantly less congested than the macrocells. To achieve…
