Learning-Based Power Allocation for Per-Beam Timing Advance Enabled Asynchronous Cell-Free Massive MIMO
Asynchronous transmission in cell-free massive multiple-input multiple-output (CF-mMIMO) systems gives rise to delay-induced inter-carrier interference (ICI) and inter-symbol interference (ISI), which can significantly reduce spectral efficiency (SE). Although per-beam timing advance (PBTA) enables beam-level timing co...
