Power saving for digital radar

An apparatus of an advanced wireless system, the apparatus comprises:

• a radar circuit including a set of transmit antennas and a set of receive antennas;
• and
• a controller operably connected to the radar circuit, including a medium access control (MAC) controller performing a scheduling operation and interference management and a configuration circuit, the controller configured to:
• in response to reporting a device capability including a maximum power and a power back off, identify a measurement configuration including a measurement gap, a set of parameters, and a sub-band structure;
• identify, based on the measurement configuration, a power control configuration for the radar circuit;
• and
• identify, based on a measurement report corresponding to the power control configuration, a power control mode including at least one of a normal mode, a low power mode, or an idle mode,
• wherein:
• the MAC controller is further configured to identify a set of waveform parameters, a set of blank formats, and power management based on the interference management, and a scheduling and measurement configuration using the scheduling operation;
• and
• the radar circuit is configured to:
• transmit a first signal at a transmit power that is determined based on the measurement report and the power control mode comprising a wideband power control mode and a sub-band power control mode, the first signal being transmitted, based on the transmit power, over the wideband power control mode or the sub-band power control mode;
• receive a second signal corresponding to the first signal, the second signal including in-phase and quadrature components for the first signal, the in-phase and quadrature components, for the first signal to be transmitted to an object, being generated based on a radar waveform;
• and
• receive the second signal being reflected from the object.
