We introduce a novel HetNet architecture employing fiber-connected distributed antenna systems, named broadband wireless access with fiber-connected massively distributed antennas (BWA-FMDA), which facilitates coordination of resource allocation and interference management. Among various opportunities realized by the proposed approach, our focus in this article is on CoMP for UMTS LTE femto- and picocells, to which we refer as femto-CoMP. Through extensive simulation results we demonstrate the superior performance gain of a femto-CoMP HetNet over independent femto- and picocell operation in traditional HetNet scenarios. We analyze both link- and system-level feasible throughput as well as scheduling delay for round-robin and proportional fair schedulers.
