Interference mitigation techniques in directional beamforming repeaters
Methods, systems, and devices for wireless communications are described that provide a repeater for beamforming a received signal at a first radio frequency via one or more scan angles or beamforming directions and then retransmitting and beamforming the transmitted signal at the first radio frequency via one or more scan angles or beamforming directions. Repeaters may perform heterodyning or downconverting on the received signal to reduce a frequency of the signal from the first frequency to an intermediate frequency (IF), and then band-pass filter the IF signal around a desired center frequency. The repeater may then heterodyne or upconvert the filtered IF signal back to the first frequency for the retransmission of the signal.
