Abstract

Signal processing and communication communities have witnessed the rise of many exciting communication technologies in recent years. Notable examples include alternative waveforms, massive multiple-input multiple-output (MIMO) signaling, non-orthogonal multiple access (NOMA), joint communications and sensing, sparse vector coding, index modulation, and so on. It is inevitable that 6G wireless networks will require a rethinking of wireless communication systems and technologies, particularly at the physical layer (PHY) since the cellular industry reached another important milestone with the development of 5G wireless networks with diverse applications. Within this perspective, this talk aims to shed light on the recent developments in reconfigurable intelligent surface (RIS)-empowered communications towards 6G wireless networks by putting forward promising candidates for future research and development. Specifically, we put our emphasis on active, transmitter-type, transmissive-reflective, and standalone RISs, by discussing their advantages and disadvantages compared to reflective RIS designs. We will also discuss recent developments in the field of next-generation RIS-assisted NOMA systems. Finally, we envision an ultimate RIS architecture, which can adjust its operation modes dynamically, and introduce the new concept of PHY slicing over RISs towards 6G wireless networks.

Abstract

Federated learning (FL) is a distributed machine learning setting where a centralized server trains a learning model by using remote devices. FL algorithms cannot be employed in wireless networks unless the unreliable and resource-constrained nature of the wireless medium is taken into account. In this talk, I shall present an FL algorithm that is suitable for cellular wireless networks in a real-world scenario. I shall discuss its convergence properties and the effects of local computation steps and communication steps on its convergence. Through experiments on real and synthetic datasets, I shall demonstrate the performance of the proposed algorithm. Also, I will present several applications of FL in 6G communications scenarios.
