The invention concerns a method for performing frequency selective control channel scheduling in networks using an OFDM spectrum, whereby a base station (BS-BS) broadcasts on at least one predefined subcarrier which is known to all mobile terminals (T-T) a signaling information common to all mobile terminals (T-T) indicating the position of at least one subcarrier of at least one frequency selective shared control channel and at least one identification of at least one addressed mobile terminal, the base station (BS-BS) sends signaling information for said at least one addressed mobile terminal at the indicated position of said at least one subcarrier of said at least one frequency selective shared control channel, and at least one mobile terminal (T-T) measures at least one subcarrier of said at least one frequency selective shared control channel for channel quality estimation, a base station (BS-BS), a mobile terminal (T-T) and a network (CN) therefor.

The invention relates to a signal processing method which optimizes the bit error rate under pragmatic conditions. The signalling method is optimally matched to the radio channel, variable with time, in rapid sequence by means of linear operations. Uplink and downlink transmission sides are determined by an excess of antennae on the downlink transmission side. The estimations of the channel matrix in the one transmission direction, necessary for the matching of the transmitter, can, in the absence of common-channel distortions with the condition of channel reciprocity, be directly obtained from the estimations for the other transmission direction. By a suitable linear combination of the transmission signals and, optionally, also the received signals, an error-free bi-directional transmission of data streams can be achieved in Rayleigh and Rice channels with significantly lower transmission powers than in purely receiver-side linear signal processing.
