Building on the recent coded-caching breakthrough by Maddah-Ali and Niesen, the work here considers the K-user cache-aided wireless multi-antenna symmetric broadcast channel …
The degrees of freedom (DoFs) of the two-user multiple-input single-output (MISO) broadcast channel (BC) are studied under the assumption that the form, I_i,\;i=1,2, of the …

A conjecture made by Lapidoth et al. at Allerton 2005 (also an open problem presented at ITA 2006) states that the degrees of freedom (DoF) of a two user broadcast channel, where …

Recently, the Degrees-of-Freedom (DoFs) region of multiple-input-single-output (MISO) networks with imperfect channel state information at the transmitter (CSIT) has attracted …
Multi-antenna cache-aided wireless networks were thought to suffer from a severe feedback bottleneck, since achieving the maximal Degrees-of-Freedom (DoF) performance required …
N Lee, RW Heath - IEEE Transactions on Information Theory, 2013 - ieeexplore.ieee.org
This paper characterizes the degree-of-freedom (DoF) regions for the multiuser vector broadcast channel with periodic channel state information (CSI) feedback. As a part of the …
X Yi, D Gesbert - IEEE Transactions on Information Theory, 2015 - ieeexplore.ieee.org
Interference networks with no channel state information at the transmitter except for the knowledge of the connectivity graph have been recently studied under the topological …
