Ultra-dense networks (UDNs) are one of the key enabling techniques for implementation of 5G wireless communication systems, and inter-cell interference is a major issue in UDNs. Coordinated Multipoint Joint Transmission (CoMP-JT) helps reduce inter-cell interferences. However, due to randomly and densely distributed access entities in UDNs, many challenging issues need to be dealt with to implement CoMP-JT in UDNs. In this article, we aim to address the issues on how to achieve maximal per area spectral efficiency in UDNs based on CoMP-JT technology. The performance of UDNs with different joint transmission schemes are evaluated with the help of computer simulations to show the effective deployment schemes of small cells.
