  We propose a cell planning scheme to maximize the resource efficiency of a
wireless communication network while considering quality-of-service
requirements imposed by different mobile services. In dense and heterogeneous
cellular 5G networks, the available time-frequency resources are orthogonally
partitioned among different slices, which are serviced by the cells. The
proposed scheme achieves a joint optimization of the resource distribution
between network slices, the allocation of cells to operate on different slices,
and the allocation of users to cells. Since the original problem formulation is
computationally intractable, we propose a convex inner approximation.
Simulations show that the proposed approach optimizes the resource efficiency
and enables a service-centric network design paradigm.
