At least one channel impulse response in the time domain for at least one connection (CH13-CH24) between an antenna (A1, A2) of a transmitter (BS) and an antenna of a receiver (MS) is determined. Only the at least one complex coefficient related to one or more time intervals of the at least one channel impulse response with a power higher than a predefined threshold is fed back. Parameters for radio transmission are allocated to the at least one connection (CH13-CH24) based on the at least one channel impulse response which is fed back. Network elements and a wireless communication network associated with the method are also provided.
