Center hyperedge (induced by source paper "optimal sum dof of the k user miso bc with current and delayed feedback"):
  Abstract: This work identifies the optimal sum degrees-of-freedom (DoF) of the $K$-user MISO Broadcast Channel (BC), in the presence of delayed channel-state information at the transmitter (CSIT) and additional current CSIT of imperfect precision. In a setting where the current channel estimation error scales - in the high SNR regime - as $\text{SNR}^{-\alpha}$ for $\alpha\in[0,1]$, the optimal sum-DoF takes the simple form $(1-\alpha) K/(\sum_{k=1}^K \frac{1}{k})+\alpha K$, and is the result of a novel scheme which deviates from existing efforts as it i) digitally combines interference, ii) uses MAT-type alignment where all symbols are decoded irrespective of order, and iii) utilizes a hierarchical quantizer whose output is distributed across rounds in a way that minimizes unwanted interference. These jointly deliver, for the first time, the elusive simultaneous scaling of both MAT-type delayed-CSI gains as well as ZF-type imperfect-CSI gains.
