We study two time division duplex (TDD) based schemes to enable the coexistence and integrate the benefits of a non-cooperative cellular network overlaid with small cells (SCs).
To improve the cellular energy efficiency, without sacrificing quality-of-service (QoS) at the users, the network topology must be densified to enable higher spatial reuse.
Massive multiple-input multiple-output (MIMO) is a key technology to meet the user demands in performance and quality of services (QoS) for next generation communication systems.
To apply Cyber-Physical System (CPS) technique in industrial internet, a wireless technology that is able to robustly maintain hyper connectivity between a data center and distributed UE's (User En
The large bandwidths available at the millimeter wave (mmWave) carrier frequencies (e.g., 30-100 GHz) have sparked significant interest in developing cellular systems in those bands to meet the eve

Multi-user MIMO offers big advantages over conventional point-to-point MIMO: it works with cheap single-antenna terminals, a rich scattering environment is not required, and resource allocation is
The spectral efficiency (SE) of cellular networks can be improved by the unprecedented array gain and spatial multiplexing offered by Massive MIMO.
By calculating the effective max-min SINR (signal-to-interference-plus-noise ratio) and the corresponding power controls explicitly, and selectively dropping a small number of mobiles based on a si
We consider the uplink (UL) and downlink (DL) of non-cooperative multi-cellular time-division duplexing (TDD) systems, assuming that the number N of antennas per base station (BS) and the number K
