Massive-MIMO Meets HetNet: Interference Coordination Through Spatial Blanking
Ansuman Adhikary, Harpreet S. Dhillon, Giuseppe Caire
In this paper, we study the downlink performance of a heterogeneous cellular network (HetNet) where both macro and small cells share the same spectrum and hence interfere with each…
On Uplink-Downlink Duality for Cellular IA
Vasilis Ntranos, Mohammad Ali Maddah-Ali, Giuseppe Caire
In our previous work we considered the uplink of a hexagonal cellular network topology and showed that linear "one-shot" interference alignment (IA) schemes are able to achieve the…
Achievable Rates of FDD Massive MIMO Systems with Spatial Channel Correlation
Zhiyuan Jiang, Andreas F. Molisch, Giuseppe Caire +1
It is well known that the performance of frequency-division-duplex (FDD) massive MIMO systems with i.i.d. channels is disappointing compared with that of time-division-duplex (TDD)…
Wireless Backhaul Networks: Capacity Bound, Scalability Analysis and Design Guidelines
Harpreet S. Dhillon, Giuseppe Caire
This paper studies the scalability of a wireless backhaul network modeled as a random extended network with multi-antenna base stations (BSs), where the number of antennas per BS i…
Optimum Power Control at Finite Blocklength
Wei Yang, Giuseppe Caire, Giuseppe Durisi +1
This paper investigates the maximal channel coding rate achievable at a given blocklength and error probability , when the codewords are subject to a long-term (i.e., averag…
Caching Eliminates the Wireless Bottleneck in Video-Aware Wireless Networks
Andreas F. Molisch, Giuseppe Caire, David Ott +3
Cellular data traffic almost doubles every year, greatly straining network capacity. The main driver for this development is wireless video. Traditional methods for capacity increa…
Fundamental Limits of Caching in Wireless D2D Networks
Mingyue Ji, Giuseppe Caire, Andreas F. Molisch
We consider a wireless Device-to-Device (D2D) network where communication is restricted to be single-hop. Users make arbitrary requests from a finite library of files and have pre-…
Demystifying the Scaling Laws of Dense Wireless Networks: No Linear Scaling in Practice
Song-Nam Hong, Giuseppe Caire
We optimize the hierarchical cooperation protocol of Ozgur, Leveque and Tse, which is supposed to yield almost linear scaling of the capacity of a dense wireless network with the n…
Cellular Interference Alignment: Omni-Directional Antennas and Asymmetric Configurations
Vasilis Ntranos, Mohammad Ali Maddah-Ali, Giuseppe Caire
Although interference alignment (IA) can theoretically achieve the optimal degrees of freedom (DoFs) in the -user Gaussian interference channel, its direct application comes at…
Cellular Interference Alignment
Vasilis Ntranos, Mohammad Ali Maddah-Ali, Giuseppe Caire
Interference alignment promises that, in Gaussian interference channels, each link can support half of a degree of freedom (DoF) per pair of transmit-receive antennas. However, in…
On the Average Performance of Caching and Coded Multicasting with Random Demands
Mingyue Ji, Antonia M. Tulino, Jaime Llorca +1
For a network with one sender, receivers (users) and possible messages (files), caching side information at the users allows to satisfy arbitrary simultaneous demands by se…
Caching and Coded Multicasting: Multiple Groupcast Index Coding
Mingyue Ji, Antonia M. Tulino, Jaime Llorca +1
The capacity of caching networks has received considerable attention in the past few years. A particularly studied setting is the case of a single server (e.g., a base station) and…
On the Performance of Optimized Dense Device-to-Device Wireless Networks
Song-Nam Hong, Giuseppe Caire
We consider a D2D wireless network where users are densely deployed in a squared planar region and communicate with each other without the help of a wired infrastructure. For t…
Adaptive Video Streaming in MU-MIMO Networks
Dilip Bethanabhotla, Giuseppe Caire, Michael J. Neely
We consider extensions and improvements on our previous work on dynamic adaptive video streaming in a multi-cell multiuser ``small cell'' wireless network. Previously, we treated t…
