In state-of-the-art multiuser multicell communication systems, bandwidth is a limited resource and reused in adjacent cells. A high spectral efficiency is achieved by a network-wide configuration with frequency reuse-one. In these reuse-one networks (RONs), intercell interference (ICI) emerges in the case of a unicast transmission as a critical limiting factor.
An important optimization criterion in network design is a fair distribution of the throughput among the users while maximizing the sum rate of the total network. This is a particular issue in RONs. A network-wide maximization of the signal to interference and noise ratio (SINR), which corresponds to the mitigation of intercell interference, can be achieved by the optimal assignment of the resources in the time-, frequency- and spatial domain.
