Distributed Proximal Policy Optimization for Contention-Based Spectrum Access
Akash Doshi, Jeffrey G. Andrews
The increasing number of wireless devices operating in unlicensed spectrum motivates the development of intelligent adaptive approaches to spectrum access that go beyond traditiona…
Deep Learning Predictive Band Switching in Wireless Networks
Faris B. Mismar, Ahmad AlAmmouri, Ahmed Alkhateeb +2
In cellular systems, the user equipment (UE) can request a change in the frequency band when its rate drops below a threshold on the current band. The UE is then instructed by the…
Why to Decouple the Uplink and Downlink in Cellular Networks and How To Do It
Federico Boccardi, Jeffrey Andrews, Hisham Elshaer +4
Ever since the inception of mobile telephony, the downlink and uplink of cellular networks have been coupled, i.e. mobile terminals have been constrained to associate with the same…
An Overview on 3GPP Device-to-Device Proximity Services
Xingqin Lin, Jeffrey G. Andrews, Amitava Ghosh +1
Device-to-device (D2D) communication will likely be added to LTE in 3GPP Release 12. In principle, exploiting direct communication between nearby mobile devices will improve spectr…
Towards Understanding the Fundamentals of Mobility in Cellular Networks
Xingqin Lin, Radha Krishna Ganti, Philip Fleming +1
Despite the central role of mobility in wireless networks, analytical study on its impact on network performance is notoriously difficult. This paper aims to address this gap by pr…
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…
Sensitive White Space Detection with Spectral Covariance Sensing
Jaeweon Kim, Jeffrey G. Andrews
This paper proposes a novel, highly effective spectrum sensing algorithm for cognitive radio and whitespace applications. The proposed spectral covariance sensing (SCS) algorithm e…
Coverage in Multi-Antenna Two-Tier Networks
Vikram Chandrasekhar, Marios Kountouris, Jeffrey G. Andrews
In two-tier networks -- comprising a conventional cellular network overlaid with shorter range hotspots (e.g. femtocells, distributed antennas, or wired relays) -- with universal f…
Power Control in Two-Tier Femtocell Networks
Vikram Chandrasekhar, Jeffrey G. Andrews, Tarik Muharemovic +2
In a two tier cellular network -- comprised of a central macrocell underlaid with shorter range femtocell hotspots -- cross-tier interference limits overall capacity with universal…
Spectrum Allocation in Two-Tier Networks
Vikram Chandrasekhar, Jeffrey G. Andrews
Two-tier networks, comprising a conventional cellular network overlaid with shorter range hotspots (e.g. femtocells, distributed antennas, or wired relays), offer an economically v…
Femtocell Networks: A Survey
Vikram Chandrasekhar, Jeffrey Andrews, Alan Gatherer
The surest way to increase the system capacity of a wireless link is by getting the transmitter and receiver closer to each other, which creates the dual benefits of higher quality…
Uplink Capacity and Interference Avoidance for Two-Tier Femtocell Networks
Vikram Chandrasekhar, Jeffrey G. Andrews
Two-tier femtocell networks-- comprising a conventional macrocellular network plus embedded femtocell hotspots-- offer an economically viable solution to achieving high cellular us…
