Center node: "dof analysis of the mimo broadcast channel with alternating hybrid csit"
  Abstract: We consider a    $K$   -user multiple-input single-output (MISO) broadcast channel (BC) where the channel state information (CSI) of user    $i(i=1,2,\ldots ,K)$    may be instantaneously perfect (P), delayed (D), or not known (N) at the transmitter with probabilities    $\lambda _{P}^{i}$   ,    $\lambda _{D}^{i}$   , and    $\lambda _{\vphantom {R_{j}}N}^{i}$   , respectively. In this setting, according to the three possible CSI at the transmitter (CSIT) for each user, knowledge of the joint CSIT of the    $K$    users could have at most    $3^{K}$    states. In this paper, given the marginal probabilities of CSIT (i.e.,    $\lambda _{P}^{i}$   ,    $\lambda _{D}^{i}$   , and    $\lambda _{\vphantom {R_{j}}N}^{\vphantom {r^{A}}i}$   ), we derive an outer bound for the degrees of freedom (DoF) region of the    $K$   -user MISO BC. Subsequently, we tighten this outer bound by considering a set of inequalities that capture some of the    $3^{K}$    states of the joint CSIT. One of the consequences of this set of inequalities is that for    $K\geq 3$   , it is shown that the DoF region is not completely characterized by the marginal probabilities in contrast to the two-user case. Afterwards, the tightness of these bounds is investigated through the discussion on the achievability. Finally, a two user multiple-input multiple-output BC having CSIT among P and N is considered in which an outer bound for the DoF region is provided, and it is shown that in some scenarios, it is tight.
