The following information is transmitted by means of the RA-RNTI scrambled DCI Format 1_0: Field The RA-RNTI scrambled DCI message signals the frequency and time resources assigned for the transmission of the Transport Block containing The UE looks for message during a configured window The RA-RNTI corresponding to the RACH transmission. In response to a PRACH transmission, a UE attempts to detect a DCI Format 1_0 with PDCCH CRC scrambled by Uplink carrier used for Msg1 transmission (0 for NUL carrier, and 1 for SUL carrier)ĭCI Format 1_0 is used to assign downlink resources.

Index of the specified PRACH in the frequency domain (0 ≤ f_id < 8) Index of the first slot of the specified PRACH in a system frame (0 ≤ t_id < 80) Index of the first OFDM symbol of the specified PRACH (0 ≤ s_id < 14) The RA-RNTI associated with the PRACH in which the Random Access Preamble is transmitted, is computed as: The preamble transmission is a Zadoff-Chu sequence.Įach preamble transmission is associated with an RA-RNTI. The preamble is referenced with the Random Access Preamble Id (RAPID).
