- The number of users who can simultaneously be served by a single transmitter is currently a research topic with far reaching practical significance as communication technology demands increase. This paper, published in IEEE-TIT, one of the highest-ranked communications theory journals, demonstrated an outer bound on the Degrees of Freedom (DoF) region. Significantly, it proved for the first time that in contrast to the two-user case, marginal probabilities of channel state information at the transmitter are not sufficient to characterize the DoF region. The work demonstrated the upper bound for interference-free data streams transmitter can simultaneously send to users under realistic-conditions.
