1. One or more non-transitory computer-readable media (NTCRM) comprising instructions, wherein execution of the instructions by one or more processors is to cause a user equipment (UE) to:
determine a configuration of a Long Term Evolution (LTE) Cell-specific Reference Signal (CRS) pattern of a LTE Component Carrier (CC) that fully or partially overlaps with a Fifth Generation (5G) CC based on a 5G subframe within the 5G CC aligning with a beginning or an end of an LTE subframe in the LTE CC, wherein the LTE CC operates with a first subcarrier spacing (SCS), and the 5G CC operates with a second SCS different than the first SCS;
determine one or more 5G Demodulation Reference Signal (DMRS) symbol positions within the 5G subframe based on a Physical Downlink Shared Channel (PDSCH) mapping type B scheme that will avoid reference signal collision between 5G DMRS symbols in the 5G subframe and LTE CRS symbols in the LTE subframe, based on the alignment of the 5G subframe within the 5G CC with the beginning or the end of the LTE subframe in the LTE CC; and
demodulate and decode one or more 5G DMRSs based on the determined one or more 5G DMRS symbol positions for estimating a PDSCH associated with the one or more 5G DMRSs.
