In summary, the system information transmission method provided by the present disclosure sends a system information request to a base station by using a terminal, the system information request is used to request second system information, and the base station sends second system information to the terminal, so that the terminal can request the base station. The second system information solves the problem of signaling waste caused by the base station repeatedly using the beamforming technology to broadcast system information to the terminal, and achieves the effect of saving signaling.

FIG. 3 is a flowchart of a system information transmission method according to another exemplary embodiment. The system information transmission method is applied to the system information shown in FIG. 1 and the system information broadcast by the base station to the terminal in this embodiment. Referring to the first system information, the system information requested by the terminal to the base station is referred to as the second system information, and in this embodiment, the terminal sends a separate system information request to the base station as an example, as shown in FIG. 3, the system is shown in FIG. The information transmission method includes the following steps.

In step 301, the base station broadcasts first system information to the terminal by using a beamforming technology. The first system information includes at least system information used when the terminal establishes an RRC connection with the base station.

The first system information is the most important system information and may include at least one system information or at least one information block. In this embodiment, the first system information includes at least system information used when the terminal establishes an RRC connection with the base station. Since the RRC connection is established in the random access procedure, the first system information includes at least system information used by the base station and the terminal in the random access procedure.

For example, the first system information may include an SFN (System Frame Number). And bandwidth. Of course, the first system information may also include an MIB, may also include an SFN, a bandwidth, and an SIBm, and may further include an MIB and k SIBs, where m is a positive integer from 1 to 12, and k is a positive integer from 1 to 11. .

The terminal needs to access the base station through the random access procedure, and in the random access process, the terminal needs to send the preamble of the base station to the base station. Therefore, if the preamble of the base station is not stored in the terminal, the base station may also carry the preamble in the terminal. The first system information is sent to the terminal. At this time, the first system information further includes a preamble. If the preamble of the base station is stored in the terminal, the first system information may not include the preamble.

When the terminal accesses the base station through the contention mechanism, the first system information carries a preamble sequence, and each preamble is a preamble used for access based on a contention mechanism; when the terminal accesses the base station through a non-competitive mechanism The first system information carries a preamble allocated by the base station to the terminal, and the preamble is a preamble used for access based on a non-contention mechanism.

In step 302, the terminal receives first system information broadcast by the base station using beamforming techniques.

In step 303, after establishing an RRC connection with the base station, when the system information request includes n information indication bits, and each information indication bit corresponds to at least one system information or at least one information block, the terminal is in n pieces of information. Determining an information indication bit corresponding to the second system information, setting a value of the information indication bit to a preset value, the preset value is used to indicate that the base station sends the second system information, n is a positive integer; and sending a system information request to the base station .

After receiving the first system information, the terminal triggers a random access procedure. In the random access process, the terminal sends a preamble to the base station, and the base station listens to the preamble sent by each terminal. When the base station listens to the preamble sent by the terminal, the base station generates a random access response message and sends the message to the terminal, where the terminal receives the random access. In response to the message, the base station sends a random access message three, the base station receives the random access message three, and sends a random access message four to the terminal, the terminal receives the random access message four, and establishes an RRC connection with the base station according to the random access message four. The terminal sends a random access message to the base station. The base station receives the random access message 5. The random access message 5 is used to notify the base station that the RRC connection establishment is complete.

The terminal randomly selects a preamble from the preamble sequence and sends a preamble to the base station on the PRACH (Physical Random Access Channel).

The random access response message may be a RAR (Random Access Response). The random access response message carries the index number of the preamble monitored by the base station, the time adjustment information for the uplink synchronization, the initial uplink resource indication, and the temporary C-RNTI (Cell Radio Network Temporary Identifier) )and many more. Among them, the uplink resource indication The uplink C-RNTI indicating whether the terminal sends the random access message 3 determines whether to convert to a permanent C-RNTI in the random access message 4.

When the terminal determines that the index number of the preamble in the random access response message corresponds to the preamble transmitted by itself, the terminal sends a random access message three to the base station. The random access message 3 further includes at least the identifier of the terminal, so that the base station recognizes the terminal. The random access message three may be msg3.

When the terminal identifier carried in the random access message 4 is the identifier of the terminal that is sent by the terminal in the random access message three, the terminal determines that the RRC connection can be established with the base station, and the temporary C-RNTI is converted into a permanent C- RNTI. The random access message four can be msg4.

The random access message five may be msg5.

After the terminal establishes an RRC connection with the base station, the terminal may determine the required second system information according to the service to be processed, and then generate a system information request for requesting the second system information.

Assuming that the first information indication bit is used to indicate that the SIB2 is acquired, and the preset value is 1, the terminal sets the value of the first information indication bit to 1 when the second system information that the terminal needs to acquire is SIB2; When the SIB2 is not required to be acquired, the terminal sets the value of the first information indication bit to 0. For each information indicating bit in the n information indicating bits, the terminal can set the value of each information indicating bit in the above manner, and finally obtain a system information request.

In step 304, after establishing an RRC connection with the terminal, the base station receives the system information request sent by the terminal.

In step 305, when the system information request includes n information indication bits, and each information indication bit corresponds to at least one system information or at least one information block, the base station reads each information indication bit in the system information request. The value, n is a positive integer; when there is an information indicating bit whose value is a preset value, the second system information corresponding to the information indicating bit is acquired; and the second system information is generated.

The base station reads the value of each information indicating bit. For each information indicating the value of the preset value, the base station reads the second system information corresponding to the information indicating bit.

Still using the example in step 307, when the value of the first information indication bit read by the base station is 1, the base station determines that the terminal needs to acquire SIB2 and uses SIB2 as the second system information.

In step 306, the base station transmits second system information to the terminal.

In step 307, the terminal receives the second system information returned by the base station according to the system information request.

The steps 301, 304, 305, and 306 can separately implement a system information transmission method called a base station side, and the steps 302, 303, and 307 can separately implement a system information transmission method called a terminal side.

In step 401, the 5G NB broadcasts the first system information to the UE.

In step 402, the UE establishes an RRC connection with the 5G NB.

In step 403, the UE sends a system information request to the 5G NB.

In step 404, the 5G NB sends the second system information to the UE.

FIG. 5 is a flowchart of a system information transmission method according to another exemplary embodiment. The system information transmission method is applied to the system information shown in FIG. 1 and the system information broadcast by the base station to the terminal in this embodiment.

Assuming that the first information indication bit is used to indicate that the SIB2 is acquired, and the preset value is 1, the terminal sets the value of the first information indication bit to 1 when the second system information that the terminal needs to acquire is SIB2; When the SIB2 is not required to be acquired, the terminal sets the value of the first information indication bit to 0. For each information indicating bit in the n information indicating bits, the terminal can set the value of each information indicating bit according to the above manner, and obtain the uplink information transmission carrying the system information request.

When the uplink information transmission is generated by the terminal according to step 503, the base station also reads the value of each information indication bit. For each information indicating the value of the preset value, the base station reads the second system information corresponding to the information indication bit. .

Still using the example in step 503, when the value of the first information indication bit read by the base station is 1, the base station determines that the terminal needs to acquire SIB2 and uses SIB2 as the second system information.

In step 505, the base station transmits second system information to the terminal.
