The present disclosure relates to systems and methods for operating a control signal to communicate signals using a first antenna and a first frequency band in response to determining that intra-device operations are occurring or are expected to occur, that a first amount of energy received by the first antenna is less than a threshold amount of energy, and that the first antenna is unaffected by the intra-device operations. The control signal may also delay communication of the signals in response to determining that intra-device operations are occurring, and that first amount of energy is greater than or equal to the threshold amount of energy.

Listen-before-talk systems, devices, and methods based on intra-device operations

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.
