Abstract (en)
[origin: FR2767007A1] The invention concerns a network enabling communications at different rates, with signals transmitted by successive frames each divided into elementary time intervals usable for different communications, A frequency band is allocated to communications between the base stations of a group of cells and mobile stations. Said band is subdivided into blocks of width 2<M-1>xB0, where B0 is a predetermined spectral width and M a whole number greater than 1 selected on the basis of a maximal communication rate. Each of the blocks is divided into carriers of width 2<m(i)-1>xB0, m(i) being a whole number depending on the block considered such as 1</=m(i)</=M. The distribution of blocks and carriers in the allocated frequency band is identical for all the cells of the group. In order to support a communication in one of the cells, a predetermined logic channel is selected, according to the required rate, as one or several time intervals on one of the carriers.
