标题： Massive MIMO: Instantaneous versus Statistical CSI-Based Power Allocation

摘要： 基于瞬时CSI的功率控制方案的部署需要计算密集型的信号处理操作，需要大量的资源来处理实时CSI更新和相关的开销。相反，基于统计CSI的方案能够在大规模的大规模多输入多输出（mMIMO）系统中高效地实现先进的功率分配算法，在这些系统中算法更新频率低得多。然而，在某些实际的mMIMO配置中，这些方案可能会偏离最优结果，从而需要采用基于瞬时CSI的方案。此外，在广泛采用基于瞬时CSI的资源分配和管理方案的实际应用中，它们可能会受到限制。本讲座从性能、复杂性和实际实施方面全面比较了mMIMO系统中基于统计CSI的功率分配和基于瞬时CSI的功率分配设计。 显示英文摘要

摘要： The deployment of instantaneous CSI-based power control schemes necessitates computationally intensive signal processing operations, requiring substantial resources to handle real-time CSI updates and the associated overhead. Conversely, statistical CSIbased schemes enable efficient implementation of advanced power allocation algorithms within large-scale massive MIMO (mMIMO) systems, where the algorithms are updated much less frequently. Nevertheless, these schemes may deviate from optimal results in certain practical mMIMO configurations, necessitating the adoption of instantaneous CSI-based schemes. In addition, they may be limited in practical implementation where instantaneous CSI-based resource allocation and management schemes are widely adopted. This lecture provides a comprehensive comparison between the statistical CSI-based power allocation and instantaneous CSI-based power allocation designs for mMIMO systems from performance, complexity, and practical implementation aspects.
