Joint Uplink-Downlink Capacity and Coverage Optimization via Site-Specific Learning of Antenna Settings
Ezgi Tekgul, Thomas Novlan, Salam Akoum +1
We propose a novel framework for optimizing antenna parameter settings in a heterogeneous cellular network. We formulate an optimization problem for both coverage and capacity - in…
Spatial and Statistical Modeling of Multi-Panel Millimeter Wave Self-Interference
Ian P. Roberts, Aditya Chopra, Thomas Novlan +2
Characterizing self-interference is essential to the design and evaluation of in-band full-duplex communication systems. Until now, little has been understood about this coupling i…
STEER: Beam Selection for Full-Duplex Millimeter Wave Communication Systems
Ian P. Roberts, Aditya Chopra, Thomas Novlan +2
Modern millimeter wave (mmWave) communication systems rely on beam alignment to deliver sufficient beamforming gain to close the link between devices. We present a novel beam selec…
Beamformed Self-Interference Measurements at 28 GHz: Spatial Insights and Angular Spread
Ian P. Roberts, Aditya Chopra, Thomas Novlan +2
We present measurements and analysis of self-interference in multi-panel millimeter wave (mmWave) full-duplex communication systems at 28 GHz. In an anechoic chamber, we measure th…
28 GHz Phased Array-Based Self-Interference Measurements for Millimeter Wave Full-Duplex
Aditya Chopra, Ian P. Roberts, Thomas Novlan +1
We present measurements of the 28 GHz self-interference channel for full-duplex sectorized multi-panel millimeter wave (mmWave) systems, such as integrated access and backhaul. We…
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 (…
Licensed-Assisted Access to Unlicensed Spectrum in LTE Release 13
Hwan-Joon, Kwon, Jeongho Jeon +10
Exploiting the unlicensed spectrum is considered by 3GPP as one promising solution to meet the ever-increasing traffic growth. As a result, one major enhancement for LTE in Release…
Modeling and Analyzing the Coexistence of Wi-Fi and LTE in Unlicensed Spectrum
Yingzhe Li, Francois Baccelli, Jeffrey G. Andrews +2
We leverage stochastic geometry to characterize key performance metrics for neighboring Wi-Fi and LTE networks in unlicensed spectrum. Our analysis focuses on a single unlicensed f…
Analytical Modeling of Uplink Cellular Networks
Thomas D. Novlan, Harpreet S. Dhillon, Jeffrey G. Andrews
Cellular uplink analysis has typically been undertaken by either a simple approach that lumps all interference into a single deterministic or random parameter in a Wyner-type model…
Analytical Evaluation of Fractional Frequency Reuse for Heterogeneous Cellular Networks
Thomas D. Novlan, Radha Krishna Ganti, Arunabha Ghosh +1
Interference management techniques are critical to the performance of heterogeneous cellular networks, which will have dense and overlapping coverage areas, and experience high lev…
Analytical Evaluation of Fractional Frequency Reuse for OFDMA Cellular Networks
Thomas David Novlan, Radha Krishna Ganti, Arunabha Ghosh +1
Fractional frequency reuse (FFR) is an interference management technique well-suited to OFDMA-based cellular networks wherein the cells are partitioned into spatial regions with di…
