Abstract(in English) | The IRS (Intelligent Reflecting Surface), which enables control of propagation characteristics, is attracting attention as a technology that greatly improves energy utilization efficiency in 6th generation mobile communication systems. In addition, cell-free networks are being actively researched as a new network architecture that solves the problem of inter-cell interference in conventional cellular networks. In this report, we consider a cell-free network that includes the IRS. We propose a QUBO formulation to optimize the IRS reflection coefficients when multiple BSs communicate with a user in a shadowing environment via the IRS at the same time by quantum computing. The simulation results show the effectiveness of the proposed QUBO formulation and clarifies that efficient communication can be realized by multiple access by TDMA. |
