Abstract
Methods, systems, and devices for wireless communications are described. The described techniques may enable a user equipment (UE) to reuse a same waveform type for both of a first contention-free random access (CFRA) message and an acknowledgement (ACK) message for a random access response (RAR) message from a network entity. The UE may transmit the first CFRA message using a first waveform type and via a first resource with a first resource index, and may retransmit the first waveform type via a second resource with the first resource index in response to receiving the RAR message. In some examples, the UE may not receive the RAR message. In such examples, the UE may not retransmit the waveform. That is, if the network entity does not receive the response to the RAR message, the network entity may interpret the lack of response as a negative acknowledgement (NACK).
