High-frequency wireless communication requires flexible coverage to cope with blockage and spatially varying traffic demand. This paper proposes a demand-adaptive virtual base station architecture consisting of a ground base station and UAV swarms forming distributed MIMO relays. The architecture includes two mechanism...

In this paper, we propose a physics-aware pathloss model for cooperative aerial reconfigurable intelligent surfaces (Co-ARIS) in millimeter-wave (mmWave) communications. The proposed model incorporates antenna radiation patterns, element-level scattering characteristics, line-of-sight (LoS) and non-line-of-sight (NLoS)...
