Operating Massive MIMO in Unlicensed Bands for Enhanced Coexistence and Spatial Reuse
Giovanni Geraci, Adrian Garcia-Rodriguez, David López-Pérez +3
We propose to operate massive multiple-input multiple output (MIMO) cellular base stations (BSs) in unlicensed bands. We denote such system as massive MIMO unlicensed (mMIMO-U). We…
Diversity Pulse Shaped Transmission in Ultra-Dense Small Cell Networks
Amir H. Jafari, Vijay Venkateswaran, David Lopez-Perez +1
In ultra-dense small cell networks, spatial multiplexing gain is a challenge because of the different propagation conditions. The channels associated with different transmitreceive…
What Is the True Value of Dynamic TDD: A MAC Layer Perspective
Ming Ding, David Lopez Perez, Guoqiang Mao +1
Small cell networks (SCNs) are envisioned to embrace dynamic time division duplexing (TDD) in order to tailor downlink (DL)/uplink (UL) subframe resources to quick variations and b…
Please Lower Small Cell Antenna Heights in 5G
Ming Ding, David Lopez Perez
In this paper, we present a new and significant theoretical discovery. If the absolute height difference between base station (BS) antenna and user equipment (UE) antenna is larger…
Performance Impact of LOS and NLOS Transmissions in Dense Cellular Networks under Rician Fading
Amir H. Jafari, Ming Ding, David Lopez-Perez +1
In this paper, we analyse the performance of dense small cell network (SCNs). We derive analytical expressions for both their coverage probability and their area spectral efficienc…
Uplink Performance Analysis of Dense Cellular Networks with LoS and NLoS Transmissions
Tian Ding, Ming Ding, Guoqiang Mao +3
In this paper, we analyse the coverage probability and the area spectral efficiency (ASE) for the uplink (UL) of dense small cell networks (SCNs) considering a practical path loss…
