Abstract
Systems, methods, and circuitries are disclosed for generating demodulation reference signals (DM-RS). In one example, a method for a user equipment (UE), includes receiving a configuration of a plurality of bandwidth parts (BWPs) configured with respective numerologies; generating a first pseudo-random sequence based at least in part on one or more of a physical cell ID, a virtual cell ID, a symbol index, a slot index, a frame index, a scrambling ID, or a UE ID for generation of a first DM-RS sequence, wherein a initialization seed for the first pseudo-random sequence is based on a scrambling ID and a slot index, wherein, for the plurality of BWPs a respective scrambling ID is associated with each BWP, and wherein the slot index is defined in accordance with the numerology of the associated BWP; and mapping, for a first BWP, the first DM-RS sequence to at least one DM-RS symbol.
