Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station (BS) may attempt to receive one or more random access channel (RACH) messages from one or more user equipment (UEs); and transmit, based at least in part on the determination of a completion of processing of any received RACH messages of the one or more RACH messages, an early termination message to a UE to terminate a random access response window. In some aspects, a UE may transmit another RACH message as a response to receiving the early termination message. Numerous other aspects are provided.
