Dynamic Uplink Power Control for Cell-Free Massive MIMO

Eng
Dynamic uplink power allocation is a critical challenge in cell-free massive MIMO (CF-mMIMO) networks, where distributed access points (APs) jointly serve multiple user equipment (UEs) under mobility, time-varying propagation conditions, and strong inter-

Performance and Architectural Tradeoffs in Scalable Cell-Free Massive MIMO

IEEE Access
The massive number of APs is often perceived as a complexity bottleneck for the scalable deployment of Cell-free (CF) systems. In this context, we propose various system-level results and valuable insights on some of the multidimensional design ...
