detailed description

Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While the embodiments of the present invention have been shown in the drawings, the embodiments Rather, these embodiments are provided so that this disclosure will be more fully understood and the scope of the disclosure will be fully disclosed.

The terms "comprising" and "having", and any variations thereof, are intended to cover a non-exclusive inclusion, such as a process, method, system, The product or device is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products or devices.

As shown in FIG. 1, the system information transmission method of some embodiments of the present disclosure is applied to the terminal side, and specifically includes the

following steps

11 and 12.

Step 11: When the other system information that needs to be requested includes the first system information and the second system information, according to the preset request configuration, the corresponding request information is sent to the base station.

The first system information is at least one of the other system information other SI requested by the random access message-MSG1, and the second system information is the minimum system information indicating the other system requested by the random access message three MSG3. At least one of the information, the other system information is system information other than the minimum system information. The minimum system information may display which other SIs can be requested by the MSG1, and the other SI not indicated in the minimum system information may be requested by the MSG3, that is, the minimum system information may also indicate which other SIs can be performed by the MSG3. request. That is to say, when the other SI that the terminal needs to request includes both the other SI requested by the MSG1 and the other SI requested by the MSG3, the corresponding request information is sent to the base station (gNB) according to the preset request configuration. Further, the request information is used to request the first system information and the second system information.

Specifically, for the terminal UE in the idle/inactive state, the UE may send the request information of the other SI through the MSG1 or the MSG3, and the other SI required by the UE includes the other SI requested by the MSG1. When the other SI requested by the MSG3 method is included, the corresponding request information can be sent according to the predefined request configuration.

Step 12: Receive first system information and second system information that are sent by the base station according to the request information.

After receiving the request information sent by the terminal, the base station feeds back the corresponding system information to the terminal, and after receiving the corresponding first system information and the second system information, the terminal determines a subsequent interaction policy with the base station, such as whether to perform cell weight Elective.

Specifically, the terminal may configure, by using the following request, how to send request information requesting the first system information and the second system information to the base station.

Configuration 1 Step 11 specifically includes: sending, by the MSG1 request flow, the first request information to the base station, and sending the second request information to the base station by using the MSG3 request procedure. The first request information is used to request the first system information, and the second request information is used to request the second system information. Such request configuration means that the terminal requests the first system information through the MSG1 request flow and the second system information through the MSG3 request process. The other SI can be divided into multiple system resource blocks (other SI blocks, OSIB), OSIB1, OSIB2, etc., as shown in FIG. 2, it is assumed that the other SI configured by the base station to send the request through MSG1 is OSIB1, and The other SI that the MSG3 sends the request is OSIB2, that is, the first system information is OSIB1, and the second system information is OSIB2. When the UE needs to acquire OSIB1 and OSIB2, the UE sends a request for OSIB1 through the MSG1 to obtain the OSIB1 sent by the base station; MSG3 sends a request for OSIB2 to obtain OSIB2 sent by the base station. Among them, shown in FIG. 2 is a scenario in which a request for the other SI request by MSG1 is preferentially requested. The UE preferentially requests OSB1 through MSG1, and the base station (gNB) transmits OSIB1 requested by the UE. Then, the request procedure of the MSG3 is performed, where the request procedure of the MSG3 is specifically: the UE sends the MSG1 to the gNB, and the gNB feeds back the MSG2 to the UE after receiving the MSG1, and after receiving the MSG2, the UE sends the MSG3 request OSIB2 to the gNB, and the gNB transmits the UE. The requested OSIB2.

Further, when the terminal sends the first request information to the base station by using the MSG1 request procedure, and the second request information is sent to the base station by using the MSG3 request procedure, how to determine the request sequence of the first request information and the second request information may be as follows: Ways to determine.

The first step is: sending the first request information to the base station by using the MSG1 request procedure, and sending the second request information to the base station by using the MSG3 request procedure, including: sequentially performing the MSG1 request flow to the base station according to the order of priority from high to low The MSG1 is sent, and the MSG3 is sent to the base station through the MSG3 request procedure. The priority of the MSG1 request process is higher than the priority of the MSG3 request process, or the priority of the MSG3 request process is higher than the priority of the MSG1 request process; the priority is pre-configured by the base station and sent to the terminal, or pre-configured for the terminal. of. This mode is a predefined request sequence, such as preferentially requesting the other SI requested by the MSG1 mode, or preferentially requesting the other SI requested by the MSG3 mode. The predefined request sequence may be configured by the base station to the UE, or may be pre-configured in Among the terminals. Specifically, the method determines the request order of the first request information and the second request information according to the priority of the MSG1 request process and the MSG3 request process, and when the priority of the MSG1 request process is higher than the priority of the MSG3 request process, the terminal The MSG1 is sent to the base station through the MSG1 request procedure, and then the MSG3 is sent to the base station through the MSG3 request procedure. When the priority of the MSG3 request procedure is higher than the priority of the MSG1 request procedure, the terminal preferentially sends the MSG3 to the base station through the MSG3 request procedure, and then sends the MSG1 to the base station through the MSG1 request procedure. It is worth noting that the priority of the MSG1 request process and the MSG3 request process can be delivered to the terminal by the base station configuration, or can be pre-configured before the terminal leaves the factory.

Manner 2: The first request information is sent to the base station by using the MSG1 request procedure, and the second request information is sent to the base station by using the MSG3 request procedure, where the request sequence of the first system information and the second system information is randomly determined; or Determining, according to the priority of the first system information and the second system information, a request sequence of the first system information and the second system information; sending, according to the request sequence, the MSG1 to the base station through the MSG1 request flow, and requesting the flow to the base station through the MSG3 Send MSG3. In this manner, the terminal randomly determines the request sequence of the first request information and the second request information, or the terminal determines the request sequence of the corresponding first request information and the second request information according to the priority of the other SI, and determines the request sequence. After that, the request of the other SI is performed in accordance with the request order. In this way, the UE determines the order of requests of the other SI. Specifically, the method randomly determines the request sequence of the other SI, or determines the request sequence according to the other SI priority, regardless of the manner of request.

Configuration 1 Step 11 may further include: sending, by using an MSG3 request procedure, corresponding request information to the base station. Such request configuration means that the terminal simultaneously requests the first system information and the second system information to the base station through one MSG3 request procedure.

Further, how to request the first system information and the second system information simultaneously through the MSG3 request process can be implemented in the following two manners.

Manner 3: The step of sending the corresponding request information to the base station by using the MSG3 request procedure includes: sending the MSG3 to the base station by using the MSG3 request procedure. The MSG3 is configured to request the first system information and the second system information. This way is to request the first system information and the second system information simultaneously in the MSG3. As shown in FIG. 3, it is assumed that the other SI configured by the base station to send the request by the MSG1 is OSIB1, and the other SI that sends the request through the MSG3 is OSIB2, that is, the first system information is OSIB1, and the second system information is OSIB2, and the UE needs to acquire OSIB1 and OSIB2, then the UE can request OSIB1 and OSIB2 simultaneously in MSG3. Specifically, the MSG3 request procedure is specifically as follows: the UE sends the MSG1 to the gNB, and the gNB feeds back the MSG2 to the UE after receiving the MSG1, and after receiving the MSG2, the UE sends the MSG3 request OSIB1 and OSIB2 to the gNB, and the gNB transmits the OSIB1 and the OSIB2 requested by the UE. .

Manner 4: The step of sending the corresponding request information to the base station by using the MSG3 request procedure includes: sending, by the MSG3 request flow, MSG1 to the base station, receiving the MSG2 sent by the base station according to the MSG1, and after receiving the MSG2, requesting the flow to the base station by using the MSG3 Send MSG3. The MSG1 is used to request the first system information, and indicates that the terminal needs to send the MSG3, or instructs the base station to send the random access message 2, the MSG2, and the MSG3 is used to request the second system information. In this way, although the first system information and the second system information are simultaneously requested through one MSG3 request process, since the MSG1 is sent in the MSG3 request process, the UE still requests the first system information through the MSG1, and requests the second system through the MSG3. information. As shown in FIG. 4, it is assumed that the other SI configured by the base station to send the request by the MSG1 is OSIB1, and the other SI that sends the request through the MSG3 is OSIB2, that is, the first system information is OSIB1, and the second system information is OSIB2, and the UE needs to acquire OSIB1 and OSIB2, the UE requests OSIB1 through the MSG1 in the MSG3 request process, and carries indication information in the MSG1, the indication information indicates that the UE also needs to send the MSG3, that is, the base station is instructed to send the MSG2, and the UE sends the OSIB2 in the MSG3 in the MSG3 request procedure. Request. Specifically, the request procedure of the MSG3 is specifically: the UE sends the MSG1 request OSIB1 to the gNB and carries the indication information to indicate that the UE needs to send the MSG3, or requests the gNB to send the MSG2. After receiving the MSG1, the gNB feeds back the MSG2 to the UE, and the UE receives the message. After MSG2, the MSG3 is requested to send OSIB2 to the gNB, and the gNB transmits the OSIB2 requested by the UE.

In the system information transmission method of the embodiment of the present disclosure, when the other system information other SI required by the terminal includes both the first system information requested by the MSG1 and the second system information requested by the MSG3, the request is requested from the base station according to the preset request configuration. The first system information and the second system information solve the problem that the system information request cannot be determined in this scenario, so that the terminal can normally acquire the other SI, thereby ensuring the normal interaction between the terminal and the base station. .

The above embodiment introduces the system information transmission method of the present disclosure from the terminal side. The following embodiment will further introduce the system information transmission method on the base station side with reference to the accompanying drawings.

As shown in FIG. 8, the system information transmission method of the embodiment of the present disclosure is applied to the base station side, and specifically includes the following

steps

81 and 82.

Step 81: The receiving terminal configures the sent request information according to the preset request.

The request information is used to request the first system information and the second system information. The first system information is that the minimum system information indicates that the request is requested by the random access message - MSG1, and the second system information is that the minimum system information is indicated by the random access message three MSG3. That is to say, when the other SI that the terminal needs to request includes both the other SI requested by the MSG1 and the other SI requested by the MSG3, the corresponding request information is sent to the base station (gNB) according to the preset request configuration. Further, the request information is used to request the first system information and the second system information.

Step 82: Send the first system information and the second system information to the terminal according to the request information.

After receiving the request information sent by the terminal, the base station feeds back the corresponding system information to the terminal, so that the terminal acquires the required first system information and the second system information, thereby determining a subsequent interaction policy between the terminal and the base station, such as access. The base station either ignores the base station or the like.

Specifically, the step 81 specifically includes: receiving, by the terminal, first request information sent by the MSG1 request process, and second request information sent by the MSG3 request process. The first request information is used to request the first system information, and the second request information is used to request the second system information.

The MSG1 is used to request the first system information, and indicates that the terminal needs to send the MSG3, or instructs the base station to send the random access message 2, the MSG2, and the MSG3 is used to request the second system information. It is assumed that the other SI configured by the base station to send the request by the MSG1 is the OSIB1, and the other SI that sends the request through the MSG3 is the OSIB2, that is, the first system information is OSIB1, and the second system information is OSIB2. As shown in FIG. 4, the UE sends the MSG1 to the gNB. The OSIB1 is requested to carry the indication information to indicate that the UE needs to send the MSG3, or the gNB is requested to send the MSG2. After receiving the MSG1, the gNB feeds back the MSG2 to the UE. After receiving the MSG2, the UE sends the MSG3 request OSIB2 to the gNB, and the gNB transmits the request of the UE. OSIB2.
