1. A system, comprising:
a symbol processing block configured to generate one or more log likelihood ratios (LLRs) associated with one or more data symbols; and
a channel estimation (CE) module configured to receive the one or more LLRs from the symbol processing block, and to process iterative CE (ItCE) for new radio (NR) based at least on one or more reference signals and the one or more LLRs, wherein:
the symbol processing block is configured to provide one or more hard feedback symbols;
the one or more hard feedback symbols include one or more modulated symbols; and
based on a code block-cyclic redundancy check (CB-CRC) passing, the CE module is configured to process at least one of i) the ItCE based at least on the one or more hard feedback symbols, or ii) the ItCE based on soft feedback.
