Beamforming repeaters with digitally assisted interference mitigation
Methods, systems, and devices for wireless communications are described that provide a repeater for beamforming a received signal at a millimeter wave (mmW) radio frequency via one or more scan angles or beamforming directions and then retransmitting and beamforming the signal at the mmW radio frequency. Repeaters may include analog and digital components for downconverting on the received signal to reduce a frequency of the signal from the mmW frequency to an intermediate frequency (IF) or baseband frequency, and then filtering the downconverted signal to reduce interference. The filtering may include digital filtering or a combination of analog and digital filtering, in which a set of filter coefficients for the digital filtering is selected based on beamforming parameters used to receive the signal, retransmit the signal, or both. The repeater may then upconvert the filtered signal back to the mmW frequency for the retransmission of the signal.
