具有全局反射约束的RIS辅助网络的能量效率最大化

Energy Efficiency Maximization in RIS-Aided Networks with Global Reflection Constraints

Robert K. Fotock, Alessio Zappone, Marco Di Renzo

摘要:

本文研究了具有全局反射能力的可重构智能表面(RIS)在多用户网络中的能量效率最大化问题。提出了两种优化方法来优化移动用户的功率、RIS系数和线性接收滤波器。这两种方法都是可证明收敛的,只需要凸优化问题的解决方案。数值结果表明,所提出的方法大大优于启发式资源分配方案。

英文摘要:

This work addresses the issue of energy efficiency maximization in a multi-user network aided by reconfigurable intelligent surface (RIS) with global reflection capabilities. Two optimization methods are proposed to optimize the mobile users' powers, the RIS coefficients and the linear receive filters. Both methods are provably convergent and require only the solution of convex optimization problems. The numerical results show that the proposed methods largely outperform heuristic resource allocation schemes.
