Study on coexisting 6G D-MIMO and massive MIMO networks operating in TDD
Maria Clara R. Lobão, Yuri C. B. Silva, Igor M. Guerreiro +2
In this study, the coexistence between a multiple-input and multiple-output (MIMO) primary network (PN) and a distributed MIMO (D-MIMO) secondary network (SN) is analyzed when both…
Zone-Based Interference Management for Underlay Spectrum Sharing in Cell-Free Networks
Mariana M. Ferreira, Juno V. Saraiva, Yuri C. B. Silva +4
Underlay spectrum sharing enables flexible coexistence between a primary network (PN) and a secondary network (SN), but inter-network interference remains a critical limiting facto…
A Distributed Game-Theoretic Solution for Power Management in the Uplink of Cell-Free Systems
Juno V. Saraiva, Roberto P. Antonioli, Gábor Fodor +2
This paper investigates cell-free massive multiple input multiple output systems with a particular focus on uplink power allocation. In these systems, uplink power control is highl…
Efficient Battery Usage in Wireless-Powered Cell-Free Systems with Self-Energy Recycling
Iran M. Braga, Roberto P. Antonioli, Gabor Fodor +2
