Signal reconstruction for dynamic analog-to-digital converters

A method for wireless communication at a wireless device, comprising:

• receiving a signal and reconstruction information for the signal;
• processing the received signal based at least in part on a resolution of an analog-to-digital converter resolution of the wireless device, wherein the processing results in a clipped and quantized version of the signal;
• applying the reconstruction information to the clipped and quantized version of the signal;
• and
• reconstructing the signal based at least in part on the applied reconstruction information.

An apparatus for wireless communication, comprising:

• a processor;
• memory coupled with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• apply a channel estimate to one or more samples of a time-domain signal to be transmitted to a wireless device;
• perform clipping and quantization on the one or more samples that have the channel estimate applied, wherein the clipping and quantization is based at least in part on an estimated analog-to-digital converter resolution of the wireless device;
• generate reconstruction information for the time-domain signal based at least in part on the one or more samples that have the channel estimate applied and the one or more clipped and quantized samples;
• and
• transmit the time-domain signal and the reconstruction information to the wireless device.
