[0113] Currently, the 3GPP NR Realease-17 protocol does not support repeated transmission of PRACH (Physical Random Access Channel), according to the current protocol version, the terminal (UE) sends a preamble once at the PRACH transmission opportunity indicated by the base station. According to the time-frequency position of the PRACH transmission opportunity, the UE can calculate the corresponding RA-RNTI value, then the UE listens to the PDCCH in the random access response (RAR, Random Access Response) time window, if the UE successfully descrambles and detects DCI 1_0 with the RA-RNTI value, and can identify the RAPID number in the RAR information scheduled by the DCI, the UE considers that the PRACH transmission is successful, otherwise the UE needs to resend a new PRACH, which will bring additional transmission delay.
