摘要: The degrees of freedom (DoF) the two-user multiple-input single-output (MISO) broadcast channel (BC) are studied under assumption that form, Ii, i = 1, 2, state information at transmitter (CSIT) for each user's can be either perfect (P), delayed (D) or not available (N), i.e., I1, I2 ϵ {P, N, D}, and therefore overall CSIT alternate between 9 resulting states I1I2. fraction time associated with I1I2 is denoted by parameter λI1I2 it assumed throughout λI2I1, λPN λNP, λPD λDP, λDN λND. Under this symmetry, main contribution paper a complete characterization DoF region two user MISO BC alternating CSIT. results highlight synergistic benefits tradeoffs various forms any given value.
