论文摘要
我们得出了一种快速，最佳的算法，用于解决无细胞大型MIMO网络中实用的加权最大sinr问题。优化问题首次共同涵盖了不完善的合作下的长期功率控制和分布式波束形成设计。特别是，我们考虑基于可能有限的渠道状态信息共享，以用户为中心的访问点群集。我们的最佳算法将基于干扰微积分的强大功率控制工具与最近开发的用于分布式波束形成设计的团队理论框架合并。此外，我们提出了一种变异，该变化在实践中显示出更快的收敛性。
We derive a fast and optimal algorithm for solving practical weighted max-min SINR problems in cell-free massive MIMO networks. For the first time, the optimization problem jointly covers long-term power control and distributed beamforming design under imperfect cooperation. In particular, we consider user-centric clusters of access points cooperating on the basis of possibly limited channel state information sharing. Our optimal algorithm merges powerful power control tools based on interference calculus with the recently developed team theoretic framework for distributed beamforming design. In addition, we propose a variation that shows faster convergence in practice.
