Abstract
A wireless access point is configured to communicate in millimeter wave frequency bands in the downlink direction and in sub-6 GHz frequency bands in the uplink direction. The wireless access point includes a signal processing circuit configured to generate different spatial streams signals and a frequency shift circuit configured to apply different frequency shifts to the different spatial streams signals. The wireless access point includes a mixer driven by a local oscillator, which up-converts the frequency shifted signals to millimeter wave frequency band signals, wherein the millimeter wave frequency band signals are transmitted by a MIMO transmit antenna array. A wireless communication device applies different frequency shifts to the different spatial streams signals after down-converting the signals received at a higher millimeter wave frequency to a lower frequency below 6 GHz. The wireless communication device applies no frequency-shifts to different spatial streams signals transmitted at lower frequency below 6 GHz.
