Zusammenfassung:An apparatus of user equipment (UE) includes processing circuitry coupled to a memory, where to configure the UE for DMRS processing in an NR network, the processing circuitry is to generate a plurality of binary sequences of length L, the binary sequences being arranged according to a signal quality metric. A set of CGSs is generated using the binary sequences, based on minimizing cross-correlation between subsets of binary sequences of different lengths selected from the plurality of binary sequences. A CGS is selected from the set of CGSs as a DMRS, based on uplink PRB resource allocation. The DMRS is encoded for transmission, where the encoding includes BPSK modulation and discrete Fourier transformation (DFT) spreading of the DMRS.
