Impact of Antenna Arrays Misalignment on the Near Field Distance in Terahertz Communications
Peng Zhang, Vitaly Petrov, Emil Björnson
The extremely short wavelength of terahertz (THz) communications leads to an extended radiative near-field region, in which some canonical far-field assumptions fail. Existing near…
Dynamic Scheduling and Power Control in Uplink Massive MIMO with Random Data Arrivals
Zheng Chen, Emil Björnson, Erik G. Larsson
In this paper, we study the joint power control and scheduling in uplink massive multiple-input multiple-output (MIMO) systems with random data arrivals. The data is generated at e…
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…
