Techniques are provided for implementing time reversed reference signals for radio frequency (RF) sensing operations in a communication system. An example method for generating channel reciprocity information for radio frequency sensing operations includes receiving radio frequency sensing information from a sensing node, generating a channel reciprocity prediction based at least in part on the radio frequency sensing information and a channel reciprocity prediction model, and providing an indication for time reversal precoding to the sensing node based on the channel reciprocity prediction.

This application presents an adaptive data recovery (ADR) of original data symbols from intervals or parameters of tone signals derived from a received OFDM signal, conducted without compensating distortions or noise introduced to the received OFDM signal by an OFDM transmission channel. Such ADR is implemented by converting back the derived intervals or parameters into original data symbols corresponding to distinctive sets of the intervals or parameters which the derived intervals or parameters belong to.
