In this work, we aim to minimize the deployment cost of active simultaneously transmitting and reflecting RISs (STAR-RISs) with the constraints of users’ communication quality requirements. To address this problem, we decouple the optimization problem into a transmission optimization subproblem and a deployment optimization subproblem. The transmission scheme is obtained by leveraging fractional programming (FP). In addition, we propose two approaches to efficiently obtain the deployment scheme of active STAR-RIS, namely a penalty-majorization-minimization (MM) method and a heuristic binary search method. Simulation results validated the effectiveness of the proposed algorithm in terms of deployment cost.
