Semantic-Effectiveness Filtering and Control for Post-5G Wireless Connectivity
Petar Popovski, Osvaldo Simeone, Federico Boccardi +2
The traditional role of a communication engineer is to address the technical problem of transporting bits reliably over a noisy channel. With the emergence of 5G, and the availabil…
Hybrid Spectrum Sharing in mmWave Cellular Networks
Mattia Rebato, Federico Boccardi, Marco Mezzavilla +2
While spectrum at millimeter wave (mmWave) frequencies is less scarce than at traditional frequencies below 6 GHz, still it is not unlimited, in particular if we consider the requi…
Hybrid Spectrum Access for mmWave Networks
Mattia Rebato, Federico Boccardi, Marco Mezzavilla +2
While spectrum at millimeter wave (mmWave) frequencies is less scarce than at traditional frequencies below 6 GHz, still it is not unlimited, in particular if we consider the requi…
Understanding Noise and Interference Regimes in 5G Millimeter-Wave Cellular Networks
Mattia Rebato, Marco Mezzavilla, Sundeep Rangan +2
With the severe spectrum shortage in conventional cellular bands, millimeter-wave (mmWave) frequencies have been attracting growing attention for next-generation micro- and picocel…
Spectrum Pooling in MmWave Networks: Opportunities, Challenges, and Enablers
Federico Boccardi, Hossein Shokri-Ghadikolaei, Gabor Fodor +5
Motivated by the intrinsic characteristics of mmWave technologies, we discuss the possibility of an authorization regime that allows spectrum sharing between multiple operators, al…
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…
CoMPflex: CoMP for In-Band Wireless Full Duplex
Henning Thomsen, Petar Popovski, Elisabeth de Carvalho +3
In this letter we consider emulation of a Full Duplex (FD) cellular base station (BS) by using two spatially separated and coordinated half duplex (HD) BSs. The proposed system is…
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…
Capacity Analysis of Decoupled Downlink and Uplink Access in 5G Heterogeneous Systems
Katerina Smiljkovikj, Hisham Elshaer, Petar Popovski +4
Our traditional notion of a cell is changing dramatically given the increasing degree of heterogeneity in 4G and emerging 5G systems. Rather than belonging to a specific cell, a de…
Load & Backhaul Aware Decoupled Downlink/Uplink Access in 5G Systems
Hisham Elshaer, Federico Boccardi, Mischa Dohler +1
Until the 4th Generation (4G) cellular 3GPP systems, a user equipment's (UE) cell association has been based on the downlink received power from the strongest base station. Recent…
Downlink and Uplink Decoupling: a Disruptive Architectural Design for 5G Networks
Hisham Elshaer, Federico Boccardi, Mischa Dohler +1
Cell association in cellular networks has traditionally been based on the downlink received signal power only, despite the fact that up and downlink transmission powers and interfe…
Five Disruptive Technology Directions for 5G
Federico Boccardi, Robert W. Heath, Angel Lozano +2
New research directions will lead to fundamental changes in the design of future 5th generation (5G) cellular networks. This paper describes five technologies that could lead to bo…
A Dynamic Clustering and Resource Allocation Algorithm for Downlink CoMP Systems with Multiple Antenna UEs
Paolo Baracca, Federico Boccardi, Nevio Benvenuto
Coordinated multi-point (CoMP) schemes have been widely studied in the recent years to tackle the inter-cell interference. In practice, latency and throughput constraints on the ba…
