“…For instance, Figure 7a illustrates the system model for state (I 1,t , I 2,t ) T = (D, N) T . When considering an entire transmission interval spanning multiple channel uses, the transmitters are interested in knowing the fraction of the transmission time (a) β I 1 ,I 2 during which the CSIT state is given by any pair (I 1 , I 2 ) T ∈ {P, D, N} × {P, D, N} [9] and (b) β A 1 ,A 2 during which the topology state is given by any pair (A 1 , A 2 ) T ∈ {γ, 1} × {γ, 1} [62,63]. Thus, effectively, β I 1 ,I 2 and β A 1 ,A 2 correspond to two-dimensional probability mass functions that depend on the pair of random variables (I 1 , I 2 ) and (A 1 , A 2 ), respectively [64].…”
