Holographic MIMO for Next Generation Non-Terrestrial Networks: Motivation, Opportunities, and Challenges
Giovanni Iacovelli, Chandan Kumar Sheemar, Wali Ullah Khan +4
In this article, we propose the integration of the Holographic Multiple Input Multiple Output (HMIMO) as a transformative solution for next generation Non-Terrestrial Networks (NTN…
Integration of Beyond Diagonal RIS and UAVs in 6G NTNs: Enhancing Aerial Connectivity
Wali Ullah Khan, Eva Lagunas, Asad Mahmood +3
The reconfigurable intelligent surface (RIS) technology shows great potential in sixth-generation (6G) terrestrial and non-terrestrial networks (NTNs) since it can effectively chan…
CR-Enabled NOMA Integrated Non-Terrestrial IoT Networks with Transmissive RIS
Wali Ullah Khan, Zain Ali, Asad Mahmood +3
This work proposes a T-RIS-equipped LEO satellite communication in cognitive radio-enabled integrated NTNs. In the proposed system, a GEO satellite operates as a primary network, a…
