On the flexible 5G dense deployment air interface for mobile broadband
In this paper we contemplate 5G frame structure for dense deployment. We discuss harmonized OFDM concept, in which the cyclic prefix length and subcarrier spacing are functions of carrier frequency while FFT size and base clock remain const...
Coordinated multi-antenna processing for cellular underlay device-to-device communication
We propose linear coordinated transmit-receive beamforming methods for spatial underlay direct device-to-device (D2D) communication in cellular networks where the user terminals (UTs) employ multiple antenna elements. For a D2D terminal pai...
Effect of residual of self-interference in performance of full-duplex D2D communication
This paper studies possibility of using full-duplex (FD) radios in underlay device-to-device communication (D2D) in cellular networks. We consider a cellular system with one D2D pair and one cellular user. Cellular user is sharing the radio...
A comparative study of scheduling disciplines in 5G systems for emergency communications
The hugely increasing demand for mobile broadband access to Web-based services and APPs will soon challenge even the UMTS Long Term Evolution (LTE) cellular technology and its advanced version LTE-A. For this reason the endeavor toward the ...
Prediction of channel quality after handover for mobility management in 5G
The fifth generation of wireless networks should enable the same experience to users at home, in the office or on the move thanks to seamless handover. Call admission control (CAC) provides the means to avoid call drops due to lack of resou...
Interference empowered 5G networks
In future 5G networks, in-band interference is perceived as one of the most critical performance bottlenecks. While current solutions classically treat interference as an additional source of noise, recent advances in information theory sho...
An agent-based model of the risk-based spectrum auction in the Cognitive Radio Networks
In this paper, we propose an agent-based model for spectrum trading in the shared use model of dynamic spectrum access. Spectrum trading is employed using the single-unit sealed-bid first-price auction, which takes into the account risk due...
A brief overview of 5G research activities
This paper summarizes the main initiatives toward 5G wireless communication networks. Emphasis is paid on the program and project activities as well as on the recent literature. A closer look to a wide range of European Union 5G related pro...
Evaluation of recent spectrum sharing models from the regulatory point of view
For over a decade the quest for new means to improve the efficiency of spectrum use has motivated researchers all over the world to come up with innovative concepts for spectrum sharing. During this time, several concepts have been created ...
Co-primary spectrum sharing with resource allocation in small cell network
We study co-primary spectrum sharing concept in small cell multiuser networks. Downlink transmission is considered with Rayleigh fading in interfering broadcast channel. Multiple-input-single-output (MISO) system is considered in two small ...
