Neural guard band interpolation for rf sensing

An apparatus, comprising:

• a memory;
• at least one transceiver;
• and
• at least one processor communicatively coupled to the memory and the at least one transceiver, the at least one processor configured to:
• collect first channel state information (CSI) across a bandwidth comprising a plurality of subcarriers over a first duration of time, the plurality of subcarriers comprising data subcarriers and guard band subcarriers, the first CSI comprising at least CSI from the data subcarriers;
• process at least a portion of the first CSI by a neural network to estimate second CSI for at least the guard band subcarriers over the first duration of time;
• and
• perform an RF sensing operation based on the first CSI and the second CSI.
