The apparatus transmits a PRACH to initiate a RACH procedure, the PRACH including a request for a first coverage enhancement associated with the RACH procedure. The request includes information related to at least a second coverage enhancement associated with an acknowledgement associated with the RACH procedure. The apparatus receives a random access response associated with the RACH procedure. The first coverage enhancement may correspond to a repetition request for a RRC connection request message. The second coverage enhancement may correspond to a repetition request for an RRC connection setup message. ## Claims ### Claim 1 An apparatus for wireless communication at a user equipment (UE), comprising: a memory;
