Making Cell-Free Massive MIMO Competitive With MMSE Processing and Centralized Implementation (2019, methodology): “By inserting (47) into (46), we can expand the expression as and compute each of the expectations using [22, Lemma 3] and ˆ h kl ∼ N (0 , p k τ p β 2 kl / Ψ t k l ) to obtain the ﬁnal expression in (29).”
Prospective Multiple Antenna Technologies for Beyond 5G (2019, background): “As a compromise approach, various heuristic power allocation schemes can be found in [29], [38], [39], [62], but it lies in the nature of these schemes that it is hard to evaluate how well they perform in practice.”
Foundations of User-Centric Cell-Free Massive MIMO (2020, background): “It is only in a pure TDD implementation exploiting uplink-downlink channel reciprocity that the CSI necessary for downlink precoding can be obtained at each AP without backhaul signaling [32].”
Optimal Resource Allocation in Coordinated Multi-Cell Systems (2013, methodology): “The latter is a beamforming direction that will cause zero interference to co-user i = k [23, 119].”
