“…This suggests the application of a time-sharing or rate-splitting [42] protocol to exploit all theoretical resources. How this can be done in such a way that no loss to the equal-power case occurs has recently been shown in [43].…”

“…, µ K ) ∈ R K + denotes the dual variables associated with the constraints in (12). The variables, {S k } and {τ k }, belong to the set denoted by G, which is specified by the remaining constrains in (14), (15) and (16). Also note that the Lagrangian is a convex function of both {S k } and {τ k }.…”

“…The polymatroid and the contra-polymatroid structures can be utilized to reduce significantly the computational complexity of finding the boundary points of the capacity region and the power region, respectively [13], [14]. However, the contra-polymatroid structure is non-existent for the power region when the channel exhibits fading [15] and/or the BS uses multiple antennas [16]. 1 As a result, characterization of the power region for the fading MIMO-MAC under SDMA is yet fully understood in literature.…”
