Hemispherical Antenna Array Architecture for High-Altitude Platform Stations (HAPS) for Uniform Capacity Provision
Omid Abbasi, Halim Yanikomeroglu, Georges Kaddoum
In this paper, we present a novel hemispherical antenna array (HAA) designed for high-altitude platform stations (HAPS). A significant limitation of traditional rectangular antenna…
Power Allocation for a HAPS-Enabled MIMO-NOMA System with Spatially Correlated Channels
Rozita Shafie, Mohammad Javad Omidi, Omid Abbasi +1
High-altitude platform station (HAPS) systems are considered to have great promise in the multi-tier architecture of the sixth generation (6G) and beyond wireless networks. A HAPS…
UxNB-Enabled Cell-Free Massive MIMO with HAPS-Assisted Sub-THz Backhauling
Omid Abbasi, Halim Yanikomeroglu
In this paper, we propose a cell-free scheme for unmanned aerial vehicle (UAV) base stations (BSs) to manage the severe intercell interference between terrestrial users and UAV-BSs…
Transmission Scheme, Detection and Power Allocation for Uplink User Cooperation with NOMA and RSMA
Omid Abbasi, Halim Yanikomeroglu
In this paper, we propose two novel cooperative-non-orthogonal-multiple-access (C-NOMA) and cooperative-rate-splitting-multiple-access (C-RSMA) schemes for uplink user cooperation.…
An Application-Driven Non-Orthogonal Multiple Access Enabled Computation Offloading Scheme
Qiqi Ren, Jian Chen, Omid Abbasi +3
To cope with the unprecedented surge in demand for data computing for the applications, the promising concept of multi-access edge computing (MEC) has been proposed to enable the n…
Trajectory Design and Power Allocation for Drone-Assisted NR-V2X Network with Dynamic NOMA/OMA
Omid Abbasi, Halim Yanikomeroglu, Afshin Ebrahimi +1
In this paper, we find trajectory planning and power allocation for a vehicular network in which an unmanned-aerial-vehicle (UAV) is considered as a relay to extend coverage for tw…
