The random access channel procedure for new radio NR can be designed to support multiple use cases with various requirements. The NR physical layer can support the independent configuration of resources used for the random access channel (RACH) procedures that can be transparent to user equipment (UE) devices and independent from resources configured for the UE. For instance, in the case of a standalone NR the RACH configuration can be obtained by the UE by either signaling on the NR carrier or fixed within the telecommunications standard. While in the case of non-standalone NR the RACH configuration can be obtained by the UE by broadcast or dedicated signaling on a different carrier than the NR carrier (e.g. a Long Term Evolution carrier).
