 Topic: The Path Beyond 5G: Challenges and A Glimpse from a Multiple Access Perspective!


Agenda

Is 10-year still a feasible gap between G's? Did 5G fulfill what was promised? What are the 5G lessons learned? While 5G is still under implementation in many countries of the world, the scientific community (i.e., International Telecommunications Union) started to work on beyond 5G standardization even though there are some unconnected dots which still need to be connected. One of the unaddressed issues is related to massive connectivity (one of the pillars of 5G), especially on how to deal with multi-user interference. Since the fundamental limits of multi-user multi-antenna communications with imperfect channel state information (CSI) are still an open problem, 5G design relied on a kind of "robustification" instead of being designed from scratch to be truly robust to imperfect CSI.

 This talk will first discuss the journey and challenges beyond 5G. After a brief summary on the road ahead, the need of a flexible and robust multiple access framework to tackle multi-user interference in a general system setup will be emphasized, in which rate-splitting multiple access (RSMA) will be proposed as a potential candidate to cope with that. Three dual-polarized downlink transmission approaches for a massive multiple-input multiple-output (MIMO) rate-splitting multiple access (RSMA) network under the effects of polarization interference and residual errors of imperfect successive interference cancellation (SIC). In addition, the potential synergy between intelligent reflecting surface (IRS) and RSMA will be discussed, in which it will be exploited the advanced capabilities of dual-polarized IRS for unleashing an enhanced RSMA polarization multiplexing. Finally, it will be presented a general idea on how to implement a space-efficient method for realizing enhanced and adaptive integrated communication and powering. In a nutshell, the talk aims to provide a big picture on the path beyond 5G, focusing on some unaddressed points and showing a glimpse from a multiple access perspective.
