Uplink Sounding Reference Signal Coordination to Combat Pilot Contamination in 5G Massive MIMO
Lorenzo Galati Giordano, Luca Campanalonga, David Lopez-Perez +4
To guarantee the success of massive multiple-input multiple-output (MIMO), one of the main challenges to solve is the efficient management of pilot contamination. Allocation of ful…
What is the Optimal Network Deployment for a Fixed Density of Antennas?
Xuefeng Yao, Ming Ding, David Lopez Perez +2
In this paper, we answer a fundamental question: when the total number of antennas per square kilometer is fixed, what is the optimal network deployment? A denser network with a le…
On the Fundamental Characteristics of Ultra-Dense Small Cell Networks
Ming Ding, David Lopez-Perez, Holger Claussen +1
In order to cope with the forecasted 1000x increase in wireless capacity demands by 2030, network operators will aggressively densify their network infrastructure to reuse the spec…
Indoor Massive MIMO Deployments for Uniformly High Wireless Capacity
Giovanni Geraci, Adrian Garcia-Rodriguez, David Lopez-Perez +3
Providing consistently high wireless capacity is becoming increasingly important to support the applications required by future digital enterprises. In this paper, we propose Eigen…
Ultra-Dense Networks: A New Look at the Proportional Fair Scheduler
Ming Ding, David Lopez Perez, Amir H. Jafari +2
In this paper, we theoretically study the proportional fair (PF) scheduler in the context of ultra-dense networks (UDNs). Analytical results are obtained for the coverage probabili…
Resource Scheduling for Mixed Traffic Types with Scalable TTI in Dynamic TDD Systems
Qi Liao, Paolo Baracca, David Lopez-Perez +1
This paper analyses the performance benefits of a user-centric scheduling approach, exploiting the flexibility of both dynamic time division duplex (TDD) and a variable transmissio…
