Publisher: | Institute of Electrical and Electronics Engineers Inc. | Abstract: | In this work, we consider the deployment of reconfigurable intelligent surfaces (RISs) to extend the coverage of a millimeter-wave (mmWave) network in indoor dense spaces. We first integrate RIS into ray-tracing simulations to realistically capture the propagation characteristics, then formulate a non-convex optimization problem that minimizes the number of RISs under rate constraints. We propose a feasible point pursuit and successive convex approximation-based algorithm, which solves the problem by jointly selecting the RIS locations, optimizing the RIS phase-shifts, and allocating time resources to user equipments (UEs). The numerical results demonstrate substantial coverage extension by using at least four RISs, and a data rate of 130 Mbit/s is guaranteed for UEs in the considered area of an airplane cabin. © 2023 IEEE. | Description: | 2023 IEEE International Conference on Communications, ICC 2023 -- 28 May 2023 through 1 June 2023 -- 193943 | URI: | https://doi.org/10.1109/ICC45041.2023.10279515 https://hdl.handle.net/20.500.11851/10877 |
