Is there any parameter that indicates CORESET with the DCI sent for the RAR message?

Hello everyone.

In the process of initial access between the gNB and the UE, the gNB needs to send a RAR message in order to complete the process.

The sending of the RAR message occurs after a PRACH message is received, the PRACH message is sent at a certain time and frequency that is marked in advance within the SIB message 1.

I want to know if there is a parameter that defines to the UE where the RAR message is going to be transmitted?

Is there any parameter that indicates CORESET with the DCI sent for the RAR message?
