  • Step 201 The UE sends msg1 to the base station.
  • the UE sending msg1 to the base station can be specifically implemented through the following process:
  • the UE determines the relationship between the synchronization signal block (Synchronization Signal Block, SSB) and the physical random access channel (Physical Random Access Channel, PRACH) resources (configured by higher layers);

  • PRACH Physical Random Access Channel
  • the UE receives a set of SSBs and determines its Reference Signal Received Power (RSRP) value, and selects the appropriate SSB according to the threshold;
  • RSRP Reference Signal Received Power
  • the UE determines the PRACH resource based on the selected SSB and the corresponding relationship between the SSB and the PRACH resource;
  • the UE sends the preamble on the PRACH time-frequency domain resources.
  • Step 202 The UE receives msg2 sent by the base station.
  • the UE receiving the msg2 sent by the base station can be specifically implemented through the following process:
  • the UE After the UE sends msg1, it opens a RAR window and monitors the PDCCH during the operation of the window.
  • the PDCCH is a PDCCH scrambled with RA-RNTI.
  • RA-RNTI is related to the PRACH time-frequency resource selected by the UE. The calculation of RA-RNTI is as follows:
  • RA-RNTI 1+s_id+14 ⁇ t_id+14 ⁇ 80 ⁇ f_id+14 ⁇ 80 ⁇ 8 ⁇ ul_carrier_id

  • Uplink Grant used to indicate resources for uplink transmission of Msg3.
  • TC-RNTI Temporary cell RNTI (Temporary C-RNTI), used for the terminal to subsequently scramble the sent Msg3 message.
  • Step 203 The UE sends msg3 to the base station.
  • msg3 is mainly used to send UE ID to the network to resolve contention conflicts. For example, if it is an initial access random process, msg3 will carry an RRC layer message, that is, CCCH SDU, which contains the UE ID and a connection establishment request (RRCSetupRequest); if it is an RRC reestablishment, it will carry a reestablishment request (RRCRestablishmentRequest). ).
  • Step 204 The UE receives msg4 sent by the base station.
  • msg4 has two functions. The first is to resolve contention conflicts; the second is to transmit RRC configuration messages to the terminal. Whether to transmit the RRC configuration message depends on the triggering condition of the random access process and the scheduling strategy of the network side, and has nothing to do with the conflict resolution itself.
  • competition conflicts there are two ways to resolve competition conflicts:
  • Method 2 If the UE does not carry C-RNTI in msg3, such as initial access, msg4 uses TC-RNTI scrambled PDCCH scheduling; the conflict resolution is to receive the PDSCH of msg4 through the UE, and match the CCCH SDU in the PDSCH .

  • msg1 and msg3 will have multiple additional transmission opportunities.
  • the UE will perform LBT on these transmission opportunities respectively.
  • the UE can use one of the successful transmission opportunities of LBT to transmit msg1 or msg3.
  • the first method Regardless of whether the UE performs LBT successfully, the UE must start ra-contentionResolutionTimer, the purpose of which is to allow the UE to receive the msg3 retransmission schedule sent by the network to the UE, thereby increasing the transmission opportunity;
  • the second method scheduling multiple available msg3 transmission opportunities for the UE through RAR, or configuring multiple msg3 repeated transmission opportunities in the time domain, the UE fails to perform LBT on all msg3 transmission opportunities, and the UE restarts immediately Random access resource selection, and then send msg1.
