Impact of Dual Slope Path Loss on User Association in HetNets
Nikhil Garg, Sarabjot Singh, Jeffrey Andrews
Intelligent load balancing is essential to fully realize the benefits of dense heterogeneous networks. Current techniques have largely been studied with single slope path loss mode…
Joint Rate and SINR Coverage Analysis for Decoupled Uplink-Downlink Biased Cell Associations in HetNets
Sarabjot Singh, Xinchen Zhang, Jeffrey G. Andrews
Load balancing by proactively offloading users onto small and otherwise lightly-loaded cells is critical for tapping the potential of dense heterogeneous cellular networks (HCNs).…
Tractable Model for Rate in Self-Backhauled Millimeter Wave Cellular Networks
Sarabjot Singh, Mandar N. Kulkarni, Amitava Ghosh +1
Millimeter wave (mmW) cellular systems will require high gain directional antennas and dense base station (BS) deployments to overcome high near field path loss and poor diffractio…
Analysis of Non-Coherent Joint-Transmission Cooperation in Heterogeneous Cellular Networks
Ralph Tanbourgi, Sarabjot Singh, Jeffrey G. Andrews +1
Base station (BS) cooperation is set to play a key role in managing interference in dense heterogeneous cellular networks (HCNs). Non-coherent joint transmission (JT) is particular…
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…
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…
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…
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…
Offloading in Heterogeneous Networks: Modeling, Analysis, and Design Insights
Sarabjot Singh, Harpreet S. Dhillon, Jeffrey G. Andrews
Pushing data traffic from cellular to WiFi is an example of inter radio access technology (RAT) offloading. While this clearly alleviates congestion on the over-loaded cellular net…
