Communication systems may employ transmission of feedback information and responses thereto, on a wireless connection such as a millimeter wave connection. The feedback information itself may be used to influence the beamforming or beam direction used for the transmission of the feedback information. A method can comprise determining a feedback indicator regarding reception of a transmitted waveform. The method can also comprise tailoring, for example beamforming, a signal for transmitting the feedback indicator based on a content of the feedback indicator.
