Abstract:
Methods, systems, and devices for wireless communications are described. A user equipment (UE) may use information received as part of a two-step random access channel (RACH) procedure to indicate that the two-step RACH procedure has been completed. For example, a UE may perform a two-step RACH procedure that includes the UE transmitting a first message to a base station and, in response, receiving a second message from a base station. The second message may include feedback information the UE uses to signal that the RACH procedure has been completed. In some examples, the feedback information may indicate a physical channel or grant, or both, and a third message may be transmitted by the UE based on the feedback information included in the second message. As such, the third message may serve as an indication that the second message was received, and the UE completed the RACH procedure.
