    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a configuration message from a base station including periodical configuration information. The UE may identify periodicities for transmitting different portions of a first message of a two-step random access channel (RACH) procedure based on the periodical configuration information, where the different portions include a preamble portion and a payload portion. The UE may transmit the preamble portion of the first message according to a first configuration periodicity and the payload portion of the first message during according to a second configuration periodicity.

    Abstract: Methods, systems, and devices for wireless communications are described to differentiate random access response types, such that a user equipment (UE) may identify a random access response for the UE. A UE may transmit a random access message that may be associated with a first type of random access response. The base station may be configured to communicate different types of random access responses, and may configure a random access response and an associated downlink control signal to correspond to the first type of random access response. The base station may transmit the downlink control signal to the UE by configuring different demodulation reference signals, different group identifiers, different search spaces or control resource sets, or different downlink control information. The UE may determine that the random access response is of the first type and may receive the random access response based on the decoded downlink control signal.
