论文摘要
在本文中，我们研究了智能反射表面（IRS）辅助上行链路系统的资源分配，其中基站配备了多个天线。我们建议共同优化用户的发射功率，在基站上进行主动波束成形，并在IRS上进行无源光束形成，以最大程度地提高整个系统能源效率，同时保持用户的最低率限制。这个问题属于高度可怕的非凸双次数编程问题，为此提出了基于块坐标下降的迭代解决方案。进行了广泛的模拟，以证明拟议计划的有效性以及在IRS拥有更多要素的好处。
In this paper, we study the resource allocation for an intelligent reflecting surface (IRS)-assisted uplink system, where the base station is equipped with multiple antennas. We propose to jointly optimize the transmit power of the users, active beamforming at the base station, and passive beamforming at the IRS to maximize the overall system energy efficiency while maintaining users' minimum rate constraints. This problem belongs to a highly intractable non-convex bi-quadratic programming problem, for which an iterative solution based on block coordinate descent is proposed. Extensive simulations are conducted to demonstrate the effectiveness of the proposed scheme and the benefits of having more elements at the IRS.
