1. An apparatus for wireless communication by a user equipment (UE), comprising:
one or more processors individually or collectively configured to execute instructions stored on one or more memories and to cause the UE to:
receive, from a network entity, a narrowband random access channel (RACH) configuration indicating one or more narrowband frequency resources, for a RACH procedure, that are arranged within a set of frequency resources allocated for RACH transmissions for non-narrowband UEs, wherein:
the one or more narrowband frequency resources have a bandwidth that is in compliance with a capability of the user equipment;
the capability supports a first carrier bandwidth for a first frequency range and a second carrier bandwidth for a second frequency range;
the narrowband RACH configuration includes:
a number of the one or more narrowband frequency resources; and
an offset between a starting point of the one or more narrowband frequency resources and a lowest frequency of the set of frequency resources allocated for RACH transmissions for the non-narrowband UEs; and
perform the RACH procedure based at least in part on the narrowband RACH configuration.
