Abstract: A user equipment (UE) is provided that includes a memory and a processor. The processor is configured to determine whether to send assistance information. In response to determining to send the assistance information, the processor is also configured to transmit the assistance information either via sidelink control information (SCI) or via a medium access control (MAC) control element (CE) having one or more resource selection assistance information elements.

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.
