The UE access network side needs to perform a random access procedure first to acquire RRC connection, referring to fig. 2, fig. 2 is a flowchart of a four-step random access procedure, and includes the following steps:

1. the UE sends MSG1 to the gNB: a random access preamble (Random Access Preamble).

Specifically, the UE selects a PRACH resource, and sends selected preambles (preambles) on the PRACH resource, where there are 64 total preambles, and each Preamble corresponds to an index value (index), and the index value ranges from 0 to 63.

2. gNB sends MSG2 to UE: random access response (RAR, random Access Response).

Specifically, the gNB replies to the MSG1 to send a random access response to the UE, and the UE calculates a random access-radio network temporary identifier (RA-RNTI) for scrambling scheduling information of the MSG2 according to PRACH resources for sending the Preamble. The layer data format of the media access control (MAC, media Access Control) layer of the RAR is shown with reference to fig. 3 (a), 3 (b), 3 (c) and 3 (d), wherein fig. 3 (a) is the format of E/T/R/BI MAC subheader, fig. 3 (b) is the format of E/T/RAPID MAC subheader, fig. 3 (c) is the format of MAC PDU (including MAC RARs), and fig. 3 (d) is a schematic diagram of the MAC RAR.

3. The UE sends MSG3 to the gNB: scheduling transmission (Scheduled Transmission)

Specifically, in MSG2, the network side allocates uplink resources for transmitting MSG3 to the UE, and the UE transmits MSG3 on the uplink resources (UL grant) allocated by the network side.

4. gNB sends MSG4 to UE: competition solving (Contention Resolution)

In order to shorten the time delay of the random access process and quickly enter a network side to develop service, a two-step random access process is provided. In the two-step random access procedure, MSG1 and MSG3 are transmitted simultaneously or almost simultaneously (MSG 3 can be transmitted here without waiting for MSG 2), MSG2 and MSG4 are transmitted together (one PDSCH transmission or two PDSCH transmissions). The embodiment of the application realizes the association of MSG1 and MSG3 of one UE in a 2 step RACH.

Fig. 4 is a first flowchart of a resource association method provided in an embodiment of the present application, as shown in fig. 4, where the resource association method includes the following steps:

step 401: the terminal acquires first configuration information, wherein the first configuration information comprises configuration information of a group of lead codes and a group of PUSCH resources.

In this embodiment of the present application, the terminal may be any device capable of communicating with a network, such as a mobile phone, a tablet computer, a notebook, and a vehicle-mounted terminal.

In this embodiment of the present application, the terminal receives first configuration information sent by a network device, where the network device may be a base station, for example, a gNB in 5G, or an eNB in 4G. In one embodiment, the terminal receives first configuration information sent by the network device through a system broadcast message.

In particular, the network side configures resources of the 2 step RACH for the terminal, including a set of preambles for the 2 step RACH and a set of PUSCH resources for transmitting MSG3 in the 2 step RACH.

Referring to fig. 5, for the 2 step RACH, the network side configures 4 preambles, respectively, preamble0, preamble1, preamble2, and Preamble3, and further configures 4 PUSCH resources, respectively, PUSCH1, PUSCH2, PUSCH3, and PUSCH4, and further, the 4 PUSCH resources are associated with 1 PRACH resource. Fig. 5 is an example of a group of PUSCH resources including 4 PUSCH resources, but is not limited thereto, and a group of PUSCH resources includes n PUSCH resources, where the size of n depends on the capability of the network side.

In an embodiment, the number of preambles included in the set of preambles is the same as the number of PUSCH resources included in the set of PUSCH resources. Referring to fig. 5, the number of preambles configured by the network side is 4, and the number of PUSCH resources configured is also 4.

Step 402: the terminal determines a target PRACH resource, and selects one preamble from the group of preambles as a target preamble for transmission on the target PRACH resource.

Here, the target PRACH resource may be determined by: the terminal receives a set of synchronization signal blocks (SSBs, PSS/SSS and PBCH Block), determines its corresponding reference signal received power (RSRP, reference Signal Receiving Power) measurement value, selects an appropriate SSB according to a threshold, and then determines the time-frequency resources of the PRACH based on the association of the SSB with the PRACH.

Step 403: the terminal determines second index information of a target PUSCH resource based on the first index information of the target preamble, and determines the target PUSCH resource from the group of PUSCH resources based on the second index information of the target PUSCH resource.

In this embodiment of the present application, index information of each preamble in the set of preambles has a corresponding relationship with index information of each PUSCH resource in the set of PUSCH resources. Further, the index information of different preambles corresponds to the index information of different PUSCH resources.

For example: the network side is configured with 4 preambles, namely, preamble0, preamble1, preamble2 and Preamble3, and is further configured with 4 PUSCH resources, namely, PUSCH1, PUSCH2, PUSCH3 and PUSCH4, wherein, preamble0 corresponds to PUSCH4, preamble1 corresponds to PUSCH3, preamble2 corresponds to PUSCH2, and Preamble3 corresponds to PUSCH 1.

The correspondence between the index information of the preamble and the index information of the PUSCH resource is not limited to this, and the correspondence between the index information of the preamble and the index information of the PUSCH resource may be represented by one functional relationship.

In particular, the terminal determines the second index information of the target PUSCH resource based on the following formula: index 2=index 1 mod n;

wherein index2 represents second index information of the target PUSCH resources, index1 represents first index information of the target preamble, n represents the number of PUSCH resources included in the group of PUSCH resources, and mod represents a remainder operation.

Note that in the formula index 2=index 1 mod n, the index2 corresponding to the different values of n needs to be different, so that the network side can pair the MSG1 and the MSG3 sent by one UE correctly.

Step 404: and the terminal transmits MSG3 on the target PUSCH resource.

In this embodiment, after a network side correctly pairs MSG1 and MSG3 sent by one UE, the network side correctly sends an RAR, that is, MSG2, to the UE, and then, the UE calculates a Random Access-radio network temporary identifier (RA-RNTI, random Access-Radio Network Tempory Identity) according to the selected PRACH resource, and descrambles a physical downlink control channel (PDCCH, physical Downlink Control Channel) for scheduling MSG2 by using the RA-RNTI, thereby obtaining MSG2.

Fig. 6 is a second flowchart of a resource association method provided in an embodiment of the present application, as shown in fig. 6, where the resource association method includes the following steps:

step 601: the network device sends first configuration information, wherein the first configuration information comprises configuration information of a group of preambles and a group of PUSCH resources.

In the embodiment of the present application, the network device may be a base station, for example, a gNB in 5G, or an eNB in 4G. In one embodiment, the network device transmits the first configuration information via a system broadcast message.

Step 602: the network device detects a preamble on PRACH resources and MSG3 on PUSCH resources, and determines the preamble and MSG3 belonging to a terminal according to the corresponding relation between the preamble and the PUSCH resources.

For a terminal side, the terminal determines a target PRACH resource, and selects one preamble from the group of preambles as a target preamble to transmit on the target PRACH resource. The terminal determines second index information of a target PUSCH resource based on the first index information of the target preamble, and determines the target PUSCH resource from the group of PUSCH resources based on the second index information of the target PUSCH resource. And the terminal transmits MSG3 on the target PUSCH resource. The technical implementation at the terminal side here can be understood with reference to the description of the method shown in fig. 4 described above.

In particular, the preamble and MSG3 belonging to one terminal are determined based on the following formula: index 2=index 1 mod n;

wherein index2 represents second index information of a target PUSCH resource transmitting MSG3, index1 represents first index information of a target preamble, n represents the number of PUSCH resources included in the group of PUSCH resources, and mod represents a remainder taking operation.

In the embodiment of the present application, after a network side correctly pairs an MSG1 and an MSG3 sent by a UE, the network side correctly sends an RAR, that is, an MSG2, to the UE, and then, the UE calculates an RA-RNTI according to a selected PRACH resource, and descrambles a PDCCH for scheduling the MSG2 by using the RA-RNTI, thereby obtaining the MSG2.
