Message repetition configurations for random access procedures

A method for wireless communication at a base station, comprising:

• transmitting an indication of a random access response (RAR) window configuration, the RAR window configuration indicating one or more first segments of a RAR window supporting a single instance of control information and indicating one or more second segments of the RAR window supporting repeated instances of the control information;
• determining whether a random access procedure is operating within the one or more first segments of the RAR window or operating within the one or more second segments based on whether a scheduled RAR communication is scheduled within the one or more first segments of the RAR window or scheduled within the one or more second segments;
• and
• transmitting, based on the determining, the single instance of the control information or the repeated instances of the control information in one or more slots of the RAR window.

An apparatus for wireless communication at a user equipment, comprising:

• a processor,
• memory in electronic communication with the processor, and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• receive, from a base station, an indication of a random access response (RAR) window configuration, the RAR window configuration indicating one or more first segments of a RAR window supporting a single instance of control information and indicating one or more second segments of the RAR window supporting repeated instances of the control information;
• determine whether a random access procedure is operating within the one or more first segments of the RAR window or operating within the one or more second segments based on whether a scheduled RAR communication is scheduled within the one or more first segments of the RAR window or scheduled within the one or more second segments;
• and
• monitor, based on the determining, one or more slots of the RAR window for the single instance of the control information or the repeated instances of the control information.
