Interference Analysis in Spectrum Sharing Scenarios between Fixed Services and 6G Mobile Networks
Samuel S. Silva, Igor. M. Guerreiro, Yuri. C. B. Silva +1
This study investigates the feasibility of coexistence between an incumbent fixed service (FS) and a 6G network in the same location under spectrum sharing. For coexistence to be p…
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…
Interference mitigation with block diagonalization for IRS-aided MU-MIMO communications
Wilker de O. Feitosa, Igor M. Guerreiro, Fco. Rodrigo P. Cavalcanti +5
This work investigates interference mitigation techniques in multi-user multiple input multiple output (MU-MIMO) Intelligent Reflecting Surface (IRS)-aided networks, focusing on th…
