Abstract: A method and system include a symbol processing block to generate log likelihood ratios (LLRs) associated with one or more data symbols. The method and system include a channel estimation (CE) module to receive the LLRs from the symbol processing block, and to process iterative CE (ItCE) for new radio (NR) based at least on reference signals and the LLRs. The CE module can process the ItCE with a granularity of one or more resource blocks (RBs) based at least on pilot resource elements (REs) and virtual pilot REs obtained from the LLRs. The CE module can process the ItCE based at least on a frequency domain orthogonal cover codes (FD-OCC) structure of the reference signals. The reference signals can be demodulation reference signals (DMRS) configured in 5G NR. The CE module can process the ItCE by updating a CE result by adding a quantity that represents a contribution obtained from virtual pilot REs.

Abstract: An apparatus may include a receiver configured to receive a signal using a channel, a transmitter configured to transmit a representation of channel information relating to the channel, and at least one processor configured to determine a condition of the channel based on the signal, and generate the representation of the channel information based on the condition of the channel using a machine learning model. A method may include determining, at a wireless apparatus, physical layer information for the wireless apparatus, generating a representation of the physical layer information using a machine learning model, and transmitting, from the wireless apparatus, the representation of the physical layer information.
