Abstract
A radio communications system comprising a plurality of cells, each containing a base station and mobile terminals. Said system is able to manage group communications between different mobile terminals, allocating during the establishment of a group communication for each cell an uplink channel contained in an uplink carrier frequency and a downlink channel contained in a downlink carrier frequency. The system is able to manage a number of downlink channels per downlink carrier frequency strictly greater than a number of uplink channels per uplink carrier frequency.
