A mobile-radio network includes radio base stations providing radio coverage to the users of the network via antenna elements, wherein the antenna elements are equipped with at least one first communication channel and at least one second communication channel. The first communication channel provides a first layer of individual microcell radio coverage for the antenna elements. The second communication channel is made common to groups of the antenna elements and provides a second layer of virtual macrocell radio coverage, wherein the coverage of each virtual macrocell aggregates the microcell radio coverages of the antenna elements included in the respective group.
