Design and Analysis of Initial Access in Millimeter Wave Cellular Networks
Yingzhe Li, Jeffrey G. Andrews, Francois Baccelli +2
Initial access is the process which allows a mobile user to first connect to a cellular network. It consists of two main steps: cell search (CS) on the downlink and random access (…
Spatially Correlated Content Caching for Device-to-Device Communications
Derya Malak, Mazin Al-Shalash, Jeffrey G. Andrews
We study optimal geographic content placement for device-to-device (D2D) networks in which each file's popularity follows the Zipf distribution. The locations of the D2D users (cac…
Optimizing Content Caching to Maximize the Density of Successful Receptions in Device-to-Device Networking
Derya Malak, Mazin Al-Shalash, Jeffrey G. Andrews
Device-to-device (D2D) communication is a promising approach to optimize the utilization of air interface resources in 5G networks, since it allows decentralized opportunistic shor…
Optimizing The Spatial Content Caching Distribution for Device-to-Device Communications
Derya Malak, Mazin Al-Shalash, Jeffrey G. Andrews
We study the optimal geographic content placement problem for device-to-device (D2D) networks in which the content popularity follows the Zipf law. We consider a D2D caching model…
Cell-Edge-Aware Precoding for Downlink Massive MIMO Cellular Networks
Howard H. Yang, Giovanni Geraci, Tony Q. S. Quek +1
We propose a cell-edge-aware (CEA) zero forcing (ZF) precoder that exploits the excess spatial degrees of freedom provided by a large number of base station (BS) antennas to suppre…
Guard Region Model for Pilot Reuse Analysis in Uplink Massive MIMO Systems
Yuwei Ren, Yingzhe Li, Jeffrey G. Andrews +1
Massive multiple-input multiple-output (MIMO) are expected to significantly enhance the spectrum efficiency (SE) and energy efficiency (EE) of future cellular systems. Since the pe…
Modeling and Analyzing Millimeter Wave Cellular Systems
Jeffrey G. Andrews, Tianyang Bai, Mandar Kulkarni +3
We provide a comprehensive overview of mathematical models and analytical techniques for millimeter wave (mmWave) cellular systems. The two fundamental physical differences from co…
Gains of Restricted Secondary Licensing in Millimeter Wave Cellular Systems
Abhishek K. Gupta, Ahmed Alkhateeb, Jeffrey G. Andrews +1
Sharing the spectrum among multiple operators seems promising in millimeter wave (mmWave) systems. One explanation is the highly directional transmission in mmWave, which reduces t…
A Primer on Cellular Network Analysis Using Stochastic Geometry
Jeffrey G. Andrews, Abhishek K. Gupta, Harpreet S. Dhillon
This tutorial is intended as an accessible but rigorous first reference for someone interested in learning how to model and analyze cellular network performance using stochastic ge…
Downlink and Uplink Cell Association with Traditional Macrocells and Millimeter Wave Small Cells
Hisham Elshaer, Mandar N. Kulkarni, Federico Boccardi +2
Millimeter wave (mmWave) links will offer high capacity but are poor at penetrating into or diffracting around solid objects. Thus, we consider a hybrid cellular network with tradi…
