Reusing waveform types for contention-free random access procedures

A first network entity for wireless communication, comprising:

• a processing system configured to:
• perform a contention-free random access procedure, wherein, to perform the contention-free random access procedure, the processing system is configured to:
• receive, from a second network entity, a first uplink message via a first resource associated with a first resource index and via a first waveform type;
• transmit, to the second network entity and in response to the first uplink message, a random access response message;
• and
• receive, from the second network entity and in response to the random access response message, a second uplink message via a second resource associated with the first resource index and via the first waveform type.

A first network entity for wireless communication, comprising:

• a processing system configured to:
• perform a contention-free random access procedure, wherein, to perform the contention-free random access procedure, the processing system is configured to:
• receive, from a second network entity, configuration information for the contention-free random access procedure, wherein the configuration information comprises one or more resources available for transmission of a first uplink message and of a second uplink message, wherein the one or more resources are each associated with a first waveform type, and wherein the second uplink message is configured to be responsive to a random access response message triggered by the first uplink message;
• transmit, to the second network entity, the first uplink message via the one or more resources and via a first waveform that is of the first waveform type associated with the one or more resources;
• monitor, responsive to the first uplink message, for the random access response message;
• and
• refrain from transmitting, to the second network entity, the second uplink message based on failure to receive the random access response message.

• transmit, to a second network entity, configuration information for the contention-free random access procedure, wherein the configuration information comprises one or more resources available for transmission by the second network entity of a first uplink message and of a second uplink message, wherein the one or more resources are each associated with a first waveform type, and wherein the second uplink message is configured to be responsive to a random access response message triggered by the first uplink message;
• receive, from the second network entity, the first uplink message via the one or more resources and via a first waveform that is of the first waveform type associated with the one or more resources;
• transmit, to the second network entity and responsive to the first uplink message, the random access response message;
• monitor, responsive to the random access response message, for the second uplink message;
• and
• determine that absence of a reception of the second uplink message is indicative of a failure of the second network entity to receive the random access response message.
