Optimal DoF of the K-User Broadcast Channel with Delayed and Imperfect Current CSIT

Abstract

This work1 studies the optimal Degrees-of-Freedom (DoF) of the K-User MISO Broadcast Channel (BC) with delayed Channel-State Information at the Transmitter (CSIT) and with additional current noisy CSIT where the current channel estimation error scales in P−α for α ∈ [0, 1]. This papers establishes for the first time the optimal DoF in this setting thanks to… (More)
