In this article we consider network coordination as a means to provide spectrally efficient communications in cellular downlink systems. When network coordination is employed, all base antennas act together as a single network antenna array, and each mobile may receive useful signals from nearby base stations. Furthermore, the antenna outputs are chosen in ways to minimize the out-of-cell interference, and hence to increase the downlink system capacity. When the out-of-cell interference is…

This work considers the weighted average sum throughput among K users per cell in a multi-cell network where coordination is limited to a neighborhood of M antennas, and considers two types of coordination: the capacity-achieving technique based on dirty paper coding (DPC) and a simpler techniquebased on zero-forcing beamforming with per-antenna power constraints.

Coordinating multiple antenna cellular networks to achieve enormous spectral efficiency

It is observed that CCT mutes intercell interference enough, so that enormous spectral efficiency improvement associated with using multiple antennas in isolated communication links occurs as well for the base-to-user links in a cellular network.
