The reamble is referenced with the Random Access Preamble Id (RAPID). The reamble transmission is a Zadoff-Chu sequence. Each reamble transmission is associated with an RA-RNTI. 5 / 56

6 LTE RA-RNTI The RA-RNTI associated with the PRACH in which the Random Access Preamble is transmitted, is comuted as: RA-RNTI= 1 + t_id + 10 f_id Where: Identifier Descrition t_id The index of the first subframe of the secified PRACH (0 t_id <10) f_id The index of the secified PRACH within that subframe, in ascending order of frequency domain (0 f_id< 6) PDCCH DCI Format 1A N-eNB UE TS DCI Format 1_0 is used to assign downlink resources. Format 1A - CRC Scrambled with RA-RNTI In resonse to a PRACH transmission, a UE attemts to detect a DCI Format 1A with PDCCH CRC scrambled by the RA-RNTI corresonding to the RACH transmission. The UE looks for message during a configured window of length ra-resonsewindow. The RA-RNTI scrambled DCI message signals the frequency and time resources assigned for the transmission of the Transort Block containing the Random Access Resonse message. The following information is transmitted by means of the RA-RNTI scrambled DCI Format 1A: Field Bits Carrier Indicator 0 or 3 Format Discriminator 1 (should be 1 for Format 1A) Localized/Distributed VRB assignment flag Resource block assignment 1 (should be set to 0 for random access) log 2 (N RB DL (N RB DL + 1)/2) N RB DL is the system bandwidth exressed in RBs Preamble Index 6 PRACH ask Index 4 6 / 56

7 Format 1A - CRC Scrambled with C-RNTI The following information is transmitted by a DCI Format 1A with PDCCH CRC scrambled by the assigned C-RNTI: Field Bits Carrier Indicator 0 or 3 Format Discriminator 1 (should be 1 for Format 1A) Localized/Distributed VRB assignment flag 1 Resource block assignment log 2 (N RB DL (N RB DL + 1)/2) N RB DL is the system bandwidth exressed in RBs LTE Random Access Resonse N-eNB UE TS , TS The UE listens on the PDCCH addressed by the RA-RNTI. 2. nce the PDCCH with the RA-RNTI is decoded, the UE uses the RB resources in the message to receive the downlink transort block. 3. The downlink transort block contains the AC PDU. The UE AC PDU consists of one or more AC subpdus. Since multile UEs may send a Preamble in the same RACH oortunity, they will all be addressed by the same RA-RNTI. Thus, multile Random Access Resonses (RAR) may be carried in a single AC PDU (They corresond to different UEs that initiated the random access rocedure in the same RACH oortunity). Each RAR in the AC PDU is addressed to a different UE via RAPID value.

NR RA-RNTI The RA-RNTI associated with the PRACH in which the Random Access Preamble is transmitted, is comuted as: RA-RNTI= 1 + s_id + 14 t_id f_id ul_carrier_id Where: Identifier Descrition s_id Index of the first FD symbol of the secified PRACH (0 s_id < 14) t_id Index of the first slot of the secified PRACH in a system frame (0 t_id < 80) f_id Index of the secified PRACH in the frequency domain (0 f_id < 8) ul_carrier_id Ulink carrier used for sg1 transmission (0 for NUL carrier, and 1 for SUL carrier) PDCCH DCI Format 1_0 gnb UE TS DCI Format 1_0 is used to assign downlink resources.

49 In resonse to a PRACH transmission, a UE attemts to detect a DCI Format 1_0 with PDCCH CRC scrambled by the RA-RNTI corresonding to the RACH transmission. The UE looks for message during a configured window of length ra-resonsewindow. The RA-RNTI scrambled DCI message signals the frequency and time resources assigned for the transmission of the Transort Block containing the Random Access Resonse message. The following information is transmitted by means of the RA-RNTI scrambled DCI Format 1_0: Field Frequency domain resource assignment Bits log 2 (N RB DL,BWP (N RB DL,BWP + 1)/2) N RB DL,BWP is the size of CRESET 0 Time domain resource assignment 4 VRB-to-PRB maing 1 odulation and coding scheme 5 TB scaling 2 Reserved bits 16 Format 1_0 - CRC Scrambled with C-RNTI The following information is transmitted by a DCI Format 1_0 with PDCCH CRC scrambled by the assigned C- RNTI: Field Bits Identifier of DCI formats 1 log 2 (N RB DL,BWP (N RB DL,BWP + 1)/2) Frequency domain resource assignment N DL,BWP RB is the size of the active DL bandwidth art in case DCI format 1_0 is monitored in the UE secific search sace if DCH sizes <= 4 and DCI size with C-RNTI <= 3. therwise N DL,BWP RB is the size of CRESET 0 Time domain resource assignment 4 VRB-to-PRB maing 1 odulation and coding scheme 5 New data indicator 1 Redundancy version 2 49 / 56
