Abstract We consider the transmission of classical information over a quantum channel by many senders, which is a generalization of the two-sender case. The channel capacity region is shown to be a convex hull bound by the Von Neumann entropy and the conditional Von Neumann entropies. The result allows a reasonable distribution of channel capacity over the senders.
