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…
Deconstructing the Composite Channel for Beyond Diagonal RIS: Channel Estimation and Beamforming Design
Fazal-E Asim, André L. F. de Almeida, Bruno Sokal +2
As beyond-diagonal reconfigurable intelligent surfaces (BD-RISs) gain increasing attention in high-frequency wireless communications, accurate and scalable channel-estimation metho…
Decoupled Delay-Doppler and Angle Estimation in BD-RIS Sensing via Nested Tucker Decomposition
Kenneth Benício, André L. F. de Almeida, Fazal-E-Asim +4
We study single-target localization in a group-connected beyond-diagonal reconfigurable intelligent surface (BD-RIS)-assisted monostatic network with K element groups. We propose a…
PARAFAC-Based Time-Varying Channel Estimation for IRS-Aided Communications
Kenneth B. A. Benício, André L. F. de Almeida, Bruno Sokal +3
This paper proposes a tensor-based parametric channel estimation technique for IRS-assisted communication systems with time-varying channel parameters. We exploit the multidimensio…
