ABSTRACT:
The invention concerns a method for OFDM data transmission in a single-frequency multi-cell mobile network from and to mobile terminals (MT) with channel estimation by means of pilots (PILOT) of a pilot subgrid in an OFDM time-frequency grid, whereby the positions of the pilot subgrids of different cells of the mobile network are randomly or pseudo-randomly distributed, a base transceiver station, a base station controller, a mobile terminal and a mobile network therefor.
