Embodiment Construction

[0025] A mobile network according to the invention comprises a mobile terminal, at least one base transceiver station according to the invention and at least one base station controller according to the invention.

[0026] Each of said mobile terminals is connected to one of said at least one base transceiver station, and each of said at least one base transceiver station is in turn connected to said at least one base transceiver station A base station controller in the device.

[0027] Said mobile terminals comprise the functionality of a mobile terminal for OFDM transmission in a mobile network, ie these mobile terminals can be connected to the mobile network via a base transceiver station.

[0028] In a preferred embodiment, said mobile terminal comprises means for receiving information about a pseudo-random position of a pilot subgrid and means for evaluating said information in order to determine said position.

[0029] The base transceiver station according to the inven...
