The second aim is to propose a provincial model of human resources empowerment for managers and executives. To collect data, a qualitative research approach including semi-structured interviews an...

With the increasing adoption of millimeter-waves (mmWave) over cellular networks, outdoor-to-indoor (O2I) communication has been one challenging research problems due to high penetration loss buildings. To address this, we investigate practicability utilizing reconfigurable intelligent surfaces (RISs) for assisting such O2I communication. We propose a new notion prefabricated RIS-empowered wall...

Reconfigurable intelligent surface (RIS) is a new and revolutionary technology to achieve spectrum-, energy- cost-efficient wireless networks. This paper studies the resource allocation for RIS-empowered device-to-device (D2D) communication underlaying cellular network, in which an RIS employed enhance desired signals suppress interference between paired D2D links. We maximize overall network’s...
