Embodiments herein provide techniques for indication of a system frame number (SFN) in and/or associated with a random access response (RAR) for a random access procedure. A UE may transmit a physical random access channel (PRACH) preamble in a PRACH occasion (e.g., in a Msg1 or MsgA) and monitor for a message (e.g., Msg2 or MsgB) in a RAR window. The RAR window may be greater than one frame. The Msg2 or MsgB (e.g., a downlink control information (DCI) and/or a medium access control (MAC) RAR) may indicate the SFN associated with the RACH occasion. The UE may determine whether the message is for the UE or another UE based on the SFN. Other embodiments may be described and claimed.
