We analyze Coordinated Multi-Point (CoMP) transmission and reception over heterogeneous wireless networks (HetNets). Our focus is on the design of a practical algorithm for joint resource allocation (joint scheduling) in each HetNet cluster. We present one such algorithm together with its detailed analysis and evaluation under two different approaches for obtaining and utilizing channel feedback from the users.

The considered approaches as well as the evaluation methodology are fully compliant with the 3GPP LTE standard. Our evaluations reveal several important insights that are essential to achieve significant CoMP gains over HetNets.
