A virtual network is created by providing antennas (14A-C) controlled by the same radio access station (8) with control signals of virtual radio access stations. Sets of physical channels comprising the control signals are dedicated to the respective antennas (14A-C), while sets of physical channels comprising only traffic channels constitute common resources for more than one antenna. Preferably, the present invention is applied in antenna systems utilising common antenna cables (17), whereby the radio access station (8) is provided as a distributed means having a central broadcast control signal injector (74) and control signal selectors (28A-C) at the antennas (14A-C). |
