Multi-Mode High Altitude Platform Stations (HAPS) for Next Generation Wireless Networks

no code implementations5 Oct 2022 Safwan Alfattani, Wael Jaafar, Halim Yanikomeroglu, Abbas Yongaçoglu

To tackle this issue, we envision the use of a multi-mode HAPS that can adaptively switch between different modes so as to reduce energy consumption and extend the HAPS loitering time.

Resource-Efficient HAPS-RIS Enabled Beyond-Cell Communications

no code implementations23 Jul 2022 Safwan Alfattani, Animesh Yadav, Halim Yanikomeroglu, Abbas Yongacoglu

Particularly, unsupported UEs will be connected to a dedicated control station (CS) through RIS-mounted HAPS.

Optimization of Quantized Phase Shifts for Reconfigurable Smart Surfaces Assisted Communications

no code implementations19 Nov 2021 Maximiliano Rivera, Mohammad Chegini, Wael Jaafar, Safwan Alfattani, Halim Yanikomeroglu

Reconfigurable Smart Surface (RSS) is assumed to be a key enabler for future wireless communication systems due to its ability to control the wireless propagation environment and, thus, enhance communications quality.

Link Budget Analysis for Reconfigurable Smart Surfaces in Aerial Platforms

no code implementations27 Aug 2020 Safwan Alfattani, Wael Jaafar, Yassine Hmamouche, Halim Yanikomeroglu, Abbas Yongaçoglu

Specifically, we analyze the characteristics of RSS-equipped aerial platforms and compare their communication performance with that of RSS-assisted terrestrial networks, using standardized channel models.
