Energy Efficiency of Massive MIMO: Coping with Daily Load Variation
M M Aftab Hossain, Cicek Cavdar, Emil Björnson +1
Massive MIMO is a promising technique to meet the exponential growth of mobile traffic demand. However, contrary to the current systems, energy consumption of next generation netwo…
Asymptotic Analysis of Multi-Antenna Cognitive Radio Systems Using Extreme Value Theory
Ruifeng Duan, Zhong Zheng, Riku Jäntti +1
We consider a spectrum-sharing cognitive radio system with antenna selection applied at the secondary transmitter (ST). Based on the extreme value theory, we deduce a simple and ac…
Modeling the Interference Generated from Car Base Stations towards Indoor Femto-cells
Byungjin Cho, Konstantinos Koufos, Kalle Ruttik +1
In future wireless networks, a significant number of users will be vehicular. One promising solution to improve the capacity for these vehicular users is to employ moving relays or…
Coordination protocol for inter-operator spectrum sharing in co-primary 5G small cell networks
Bikramjit Singh, Sofonias Hailu, Konstantinos Koufos +4
We consider spectrum sharing between a limited set of operators having similar rights for accessing spectrum. A coordination protocol acting on the level of the Radio Access Networ…
Energy saving market for mobile operators
M. M. Aftab Hossain, Riku Jäntti, Cicek Cavdar
Ensuring seamless coverage accounts for the lion's share of the energy consumed in a mobile network. Overlapping coverage of three to five mobile network operators (MNOs) results i…
