Abstract
A user equipment (UE) configured to perform self-calibration. The UE includes a first radio configured to perform implicit beamforming and further configured to transmit and receive signals during the calibration procedure. The UE further includes a first plurality of antennas communicatively coupled to the first radio, a second radio configured to transmit and receive signals during the calibration procedure and at least one second antenna communicatively coupled to the second radio. The calibration procedure includes the second radio transmitting a tone signal over the calibration frequency and a first antenna of the first radio receiving the tone signal and a second antenna of the first radio receiving the tone signal.
