- Long Term Evolution (Long Term Evolution, LTE) random access and New Radio (New Radio, NR) conventional random access are divided into two types: competitive random access and non-competitive random access.
- competitive random access The process of competing for random access is as follows.
- Message 1 (Msg1): User Equipment (User Equipment, UE, also called terminal) selects random access preamble and physical random access channel (Physical Random Access Channel, PRACH) resources and uses the PRACH resource to send to the base station The selected random access preamble.
- Msg1 User Equipment (User Equipment, UE, also called terminal) selects random access preamble and physical random access channel (Physical Random Access Channel, PRACH) resources and uses the PRACH resource to send to the base station The selected random access preamble.
- PRACH Physical Random Access Channel
- Message 2 The base station receives the preamble and sends a random access response (RAR).
- the random access response consists of two parts: Medium Access Control (MAC) header and MAC RAR.
- the MAC header contains multiple subheaders, and its main content is Random Access Preamble ID (RAPID) and Backoff Indicator (BI).
- RAPID Random Access Preamble ID
- BI Backoff Indicator
- Figure 2 is a schematic diagram of the MAC subheader with RAPID.
- Figure 3 shows the MAC RAR format of the random access response, including the Time Advance Command (TAC), the uplink resource grant (UL Grant) for message three (Msg3), and the temporary cell radio network temporary identification (cell) allocated by the network side. Radio Network Temporary Identity, C-RNTI).
- TAC Time Advance Command
- UL Grant uplink resource grant
- C-RNTI Radio Network Temporary Identity
- Both the physical downlink control channel (PDCCH) carrying Msg2 scheduling information and the physical downlink shared channel (PDSCH) carrying Msg2 are scrambled with RA-RNTI, which is the only time-frequency resource for sending Msg1 within the window length of the UE receiving Msg2 correspond.
- RA-RNTI is the only time-frequency resource for sending Msg1 within the window length of the UE receiving Msg2 correspond.
- Msg3 The UE sends uplink transmission on the UL grant specified by Msg2.
- the content of Msg3 uplink transmission is different for different random access reasons. For example, for initial access, Msg3 transmits a radio resource control (RRC) connection establishment request.
- RRC radio resource control
- the connected UE is What is sent in Msg3 is the C-RNTI MAC control element (CE).
- CE C-RNTI MAC control element
- Msg4 contention resolution message.
- the UE judges whether the random access is successful according to Msg4.
- Msg4 For idle UEs or inactive UEs, Msg4 carries the CCCH MAC CE that contains the RRC signaling content of Msg3; for connected UEs, Msg4 uses the PDCCH that uniquely identifies the C-RNTI in the UE cell for scheduling , The PDCCH can achieve contention resolution.
- the temporary C-RNTI is converted to the unique UE identification C-RNTI of the UE in the cell after the contention is resolved successfully.
- a two-step random access process (2-step RA) is derived on the basis of 4-step RA for competitive random access, the process is shown in Figure 4.
- msgA is divided into preamble transmission on PRACH and data transmission on physical uplink shared channel (PUSCH), which is equivalent to Msg1 plus Msg3 of 4-step RA;
- msgB random access response and contention resolution are equivalent to 4-step random access channel ( RACH) Msg2 plus Msg4.
- RACH 4-step random access channel
- the base station may send various random access responses to the UE, such as:
- successRAR in order to further save time delay, it can be considered to carry SRB in successRAR (for example, RRC connection establishment, RRC connection reestablishment, etc.), but there is no clear plan on how to design successRAR.
