Abstract
The network allows communications at various bit rates, with signals transmitted in successive frames each divided into elementary timeslots which can be used for different communications. A frequency band is allocated to communications between base stations of a group of cells and mobile stations. This band is subdivided into blocks of width 2.sup.M-1.times.B.sub.0, where B.sub.0 is a predefined spectral width and M an integer greater than 1 chosen as a function of a maximum communication bit rate. Each of the blocks is divided into carriers of width 2.sup.m(i)-1.times.B.sub.0, m(i) being an integer dependent on the relevant block such that 1.ltoreq.m(i).ltoreq.M. The partition of the blocks and of the carriers within the allocated frequency band is identical for all the cells of the group. To support a communication in one of the cells, a logic channel is selected, defined, depending on the bit rate required, as one or more timeslots on one of the carriers.
