A New Achievable Region of the -User MAC Wiretap Channel with Confidential and Open Messages Under Strong Secrecy
Hao Xu, Kai-Kit Wong, Giuseppe Caire
This paper investigates the achievable region of a -user discrete memoryless (DM) multiple access wiretap (MAC-WT) channel, where each user transmits both secret and open messag…
A Modular Pragmatic Architecture for Multiuser MIMO with Array-Fed RIS
Krishan Kumar Tiwari, Giuseppe Caire
We propose a power- and hardware-efficient, pragmatic, modular, multiuser/multibeam array-fed RIS architecture particularly suited to operate in very high frequency bands (high mmW…
Unsourced Random Access in MIMO Quasi-Static Rayleigh Fading Channels with Finite Blocklength
Junyuan Gao, Yongpeng Wu, Giuseppe Caire +2
This paper explores the fundamental limits of unsourced random access (URA) with a random and unknown number of active users in MIMO quasi-static Rayleigh fading chann…
Adapt or Wait: Quality Adaptation for Cache-aided Channels
Eleftherios Lampiris, Giuseppe Caire
This work focuses on quality adaptation as a means to counter the effects of channel degradation in wireless, cache-aided channels. We design a delivery scheme which combines coded…
User-Centric Cell-Free Wireless Networks for 6G: Communication Theoretic Models and Research Challenges
Fabian Göttsch, Giuseppe Caire, Wen Xu +1
This paper presents a comprehensive communication theoretic model for the physical layer of a cell-free user-centric network, formed by user equipments (UEs), radio units (RUs), an…
Ultra-Dense Cell-Free Massive MIMO for 6G: Technical Overview and Open Questions
Hien Quoc Ngo, Giovanni Interdonato, Erik G. Larsson +2
Ultra-dense cell-free massive multiple-input multiple-output (CF-MMIMO) has emerged as a promising technology expected to meet the future ubiquitous connectivity requirements and e…
