Traffic Aware Beamformer Design for Integrated Access and Backhaul with Flexible TDD [PDF]

, 2020
Integrated access and backhaul (IAB) networks consist of IAB-donor, IAB-nodes, and user-equipments (UEs). Both IAB-donor and IAB-node provide access to UEs while IAB-donor and IAB-nodes exchange UEs data via wireless in-band backhaul using the same ...

Airborne Integrated Access and Backhaul Systems:Learning-Aided Modeling and Optimization [PDF]

, 2023
The deployment of millimeter-wave (mmWave) 5G New Radio (NR) networks is hampered by the properties of the mmWave band, such as severe signal attenuation and dynamic link blockage, which together limit the cell range.

Low Complexity Hybrid Beamforming for mmWave Full-Duplex Integrated Access and Backhaul [PDF]

, 2022
We consider an integrated access and backhaul (IAB) node operating in full-duplex (FD) mode. We analyze simultaneous transmission from the New Radio gNB to the IAB node on the backhaul uplink, IAB node to a user equipment (UE) on the access downlink, and

Beamforming Allocation and Backhaul Capacity Allocation for Integrated Access and Backhaul Networks

, 2022
In this paper, we consider beamforming vector allocation and backhaul link capacity allocation in millimeter wave (mmWave) integrated access and backhaul (IAB) networks. We consider out-of-band backhaul and each base station (BS) has a Line-of-Sight (LoS)
