Base Station Antenna Uptilt Optimization for Cellular-Connected Drone Corridors
IEEE TRANSACTIONS ON AEROSPACE AND ELECTRONIC SYSTEMS, 59(4), 4729–4737.
author keywords: Drones; Antennas; Interference; Probability; Power system reliability; Communication system security; Signal to noise ratio; Antenna uptilt; drone corridor; national airspace (NAS); outage probability; unmanned aerial vehicle (UAV); unmanned aerial vehicle traffic management
TL;DR:
This article considers the use of additional uptilted antennas at each cellular BS and optimize the uptilt angle to maximize the wireless coverage probability across a given drone corridor and characterize the optimal value of the antenna uptilt angles for a given antenna pattern as well as the minimum/maximum altitudes of the drone corridor.

Channel Rank Improvement in Urban Drone Corridors Using Passive Intelligent Reflectors
2023 IEEE AEROSPACE CONFERENCE.
TL;DR:
The results at 6 GHz, 28 GHz, and 60 GHz show that the proposed approach increases the average rates for all frequency bands for a given drone corridor when compared with the environment with no IRSs present, and IRS-aided channels perform close to each other at sub-6 and mmWave bands.

A Deep Learning Based Modeling of Reconfigurable Intelligent Surface Assisted Wireless Communications for Phase Shift Configuration
IEEE Open Journal of the Communications Society, 2, 262–272.
TL;DR:
A machine learning (ML) based modeling approach that learns the interactions between the phase shifts of the RIS elements and receiver (Rx) location attributes and uses them to predict the achievable rate directly without using channel state information (CSI) or received pilots.

CHANNEL RECONSTRUCTION WITH LIMITED FEEDBACK IN INTELLIGENT SURFACE AIDED COMMUNICATIONS
2021 IEEE 94TH VEHICULAR TECHNOLOGY CONFERENCE (VTC2021-FALL).
author keywords: Low-Rank Recovery; Non-Convex; Proximal Distance Algorithm; Sparsity; Subspace
TL;DR:
This work proposes novel channel reconstruction formulations for IRS-assisted communications where the IRS panel has only passive elements and the intended receiver provides just signal strength feedback reports and designs efficient proximal distance based algorithms to reconstruct the effective channel.

Channel Reconstruction in Intelligent Surface aided Communications
2021 INTERNATIONAL CONFERENCE ON COMMUNICATION SYSTEMS & NETWORKS (COMSNETS), pp. 531–539.
TL;DR:
This work proposes novel channel reconstruction schemes which do not require any active elements on the IRS panel and proposes an algorithm for subspace estimation and also provides a recipe for designing IRS pattern vectors that can be gainfully used during the training phase.
