Beamforming Design for Cache-enabled Integrated Access and Backhaul Networks

, 2022
In this paper, we consider a cache-enabled integrated access and backhaul (IAB) network. We first derive the sum achievable data rate. Then, we formulate the sum achievable data rate maximization problem with respect to (w.r.t.) the beamforming designs ...

Resource Allocation and Node Placement in Multi-Hop Heterogeneous Integrated-Access-and-Backhaul Networks

IEEE Access, 2020
We consider a heterogeneous MIMO-OFDMA based dense small cell (SC) system in which each macro cell base station (MBS) serves its coverage area with the help of small cell base stations (SBSs) through multi-hop wireless connections.

Two-queue polling system as a model of an integrated access and backhaul network node in half-duplex mode

Discrete and Continuous Models and Applied Computational Science
Integrated Access and Backhaul (IAB) technology facilitates the establishment of a compact network by utilizing repeater nodes rather than fully equipped base stations, which subsequently minimizes the expenses associated with the transition towards next-
