1. A method for wireless communication by a user equipment (UE), comprising:
receiving a machine-type communication (MTC) system information block (SIB) message from a network entity;
determining a random access channel (RACH) sequence indicating a coverage limitation of the UE to be sent in a transmission time interval (TTI) bundle based on the MTC SIB message; and
transmitting the RACH sequence as a narrowband transmission within one resource block (RB) in each of a plurality of TTIs of the TTI bundle based at least in part on the determining.
