This paper considers the downlink of a wireless multicell Orthogonal Frequency Division Multiple-Access (OFDMA) system where neighboring Base-Stations (BSs) can jointly encode and transmit data signals to their users using Zero-Forcing (ZF) precoding in each frequency tone, but only limited backhaul capacity is available for each BS to share its users' data streams with the neighboring BSs. A numerical algorithm is proposed to maximize the network-wide utility of this system subject to backhaul-capacity constraints.
