Claim 15:
16. An apparatus to be implemented by a user equipment (UE), the apparatus comprising:
baseband circuitry coupled with memory circuitry, the baseband circuitry to:
determine a configuration that includes frequency domain allocations corresponding to respective Long Term Evolution (LTE) component carriers (CCs) that fully or partially overlap with one or more Fifth Generation (5G) CCs based on a 5G subframe within a 5G CC of the one or more 5G CCs aligning with a beginning or an end of an LTE subframe in an LTE CC of the respective LTE CCs, 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 LTE Cell-specific Reference Signal (CRS) patterns, the one or more LTE CRS patterns defining one or more Orthogonal Frequency Division Multiplexing (OFDM) symbols in which one or more LTE CRSs are to be transmitted;
determine one or more 5G Demodulation Reference Signal (DMRS) symbol positions within the 5G subframe in which one or more 5G DMRSs are to be transmitted 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;
rate match around one or more LTE CRSs of the LTE CRS patterns that are transmitted in the respective LTE CCs that are fully or partially overlapping with the one or more 5G CCs in which a PDSCH transmission is to be received; and
demodulate and decode the 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; and
radiofrequency (RF) circuitry communicatively coupled with the baseband circuitry, the RF circuitry to receive the PDSCH transmission according to the PDSCH mapping type B scheme and based on the rate matching.
