1. A method for wireless communication by a user equipment (UE), comprising:
receiving, from a base station, a configuration message that indicates configuration information for a random access procedure, wherein the configuration information includes an indication of a repetition pattern associated with a first message of the random access procedure, and wherein the repetition pattern indicates a quantity of consecutive transmissions of a physical random access channel;
performing, based at least in part on the repetition pattern indicated in the configuration information, the quantity of consecutive transmissions of the physical random access channel;
following a last transmission of the quantity of consecutive transmissions of the physical random access channel, performing, based at least in part on the repetition pattern indicated in the configuration information, repeated transmissions of a physical uplink shared channel associated with the first message;
monitoring, based at least in part on performing a first repeated transmission of the physical uplink shared channel and based at least in part on the repetition pattern, for a second message of the random access procedure from the base station;
detecting, based at least in part on the monitoring, the second message of the random access procedure from the base station prior to transmitting a last transmission of the repeated transmissions of the physical uplink shared channel; and
ceasing remaining transmissions of the repeated transmissions of the physical uplink shared channel based at least in part on detecting the second message.
