1. One or more non-transitory computer readable media having instructions thereon that, in response to execution by one or more processing devices of a user equipment (UE), cause the UE to:

  • determine a physical layer cell identity corresponding to a cell of an evolved universal mobile telecommunication system terrestrial radio access network (E-UTRAN);

    receive an indicator of a virtual cell identity via radio resource control signaling, the virtual cell identity different from a physical layer cell identity corresponding to a cell of an evolved universal mobile telecommunication system terrestrial radio access network (E-UTRAN);

    receive a cyclic shift hop initialization value different from the virtual cell identity;

    generate a demodulation reference signal (DM-RS) parameter based at least in part on the virtual cell identity, andgenerate a cyclic shift for a DM-RS by initializing a pseudo-random sequence generator with the cyclic shift hop initialization value.
