More Information
Summary:The invention concerns a method for distributing data on an OFDM time-frequency grid for data transmission from and to mobile terminals in a mobile network accommodating the use of pilot subgrids suitable for channel estimation, whereby said OFDM time-frequency grid comprises different frequency patterns, subcarrier frequencies of said different frequency patterns are interleaved, in at least one interleaving interval, as many cyclic shifts of the respective part of the frequency patterns are performed, rotating the allocation of the subcarrier frequencies to the different frequency patterns, as must be performed so that the distribution of the pilot subgrids over the frequency patterns leads for each pilot subgrid to no more than a maximum defined number of pilots that lie within each frequency pattern, a base transceiver station, a base station controller and a mobile network therefor.
