For such high-frequency networks, base stations and user equipment (English: User Equipment; abbreviation: The UE needs to use beamforming to transmit data to meet the channel quality requirements in the high-frequency data transmission process. One problem of using beamforming to transmit data is how to provide system information.

The system information can be divided into a main information module (English: Master Information Block; MIB) and a plurality of system information modules (English: System Information Blocks; referred to as: SIBs). In the related art, system information of a Long Term Evolution (LTE) network is transmitted by a base station through omnidirectional broadcasting. Among them, SIB1 (core system information module) and MIB have a fixed transmission period, and scheduling information of other SIBs is broadcast in SIB1. When the system information in the LTE network changes, on the one hand, the system information value tag in the SIB1 can be changed to notify the UE that the system information has changed; on the other hand, the eNB can be in the paging.

detailed description

The present disclosure will be further described in detail with reference to the accompanying drawings, in which FIG. . All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present disclosure without departing from the inventive scope are the scope of the disclosure.

Referring to FIG. 1 , it is a schematic diagram of an implementation environment involved in a method for acquiring system information provided by an embodiment of the present disclosure. The implementation environment can include at least one base station 101 and at least one user equipment 102.

In the 5G system, the at least one base station 101 may be a next generation base station (English: generation Node B; abbreviated as: gNB). In the LTE system, the at least one base station 101 may be an evolved base station (English: evolved Node B; : eNB), the at least one user equipment 102 can be a smartphone, a computer, a multimedia player, an e-reader, a wearable device, or the like. A connection may be established between the base station 101 and the user equipment 102 over a wireless network, and the base station 101 may transmit system information to the user equipment 102.

It should be noted that in the RAN2#95 conference in August 2016, the system information in the 5G system can be divided into minimum system information (English: Minimum SI) and multiple other system information (English: Other SI), among which The definitions of minimum SI and other SI include:

"Minimum SI": Minimum SI needs to be broadcasted periodically. Content will at least include information to support cell selection, for acquiring other SI, for accessing the cell. (Chinese: Minimum system information needs to be broadcast periodically. Minimum system letter The content of the information includes at least information supporting cell selection, obtaining other system information, and information of accessing the cell. )

"Other SI": Other SI includes everything not broadcasted in minimum SI. (Chinese: Other system information includes everything except information transmitted by the minimum system information.)

FIG. 2 is a flowchart of a method for acquiring system information according to an exemplary embodiment of the present disclosure. The method is applied to a UE. As shown in FIG. 2, the method may include:

Step 201: Receive indication information sent by the base station, where the indication information includes an identifier of the first other SI, where the first other SI is any other SI in the base station.

Step 202: After determining that the indication information indicates that the first other SI has been updated, send a receiving request to the base station, where the receiving request includes: an identifier of the first other SI.

Step 203: Receive update information sent by the base station, where the update information includes the updated first other SI.

In summary, in the method for acquiring system information provided by the embodiment of the present disclosure, the UE may receive the indication information sent by the base station, and after determining the first other SI update according to the indication information, send the identifier including the first other SI to the base station. Receiving the request and receiving the updated first other SI sent by the base station, in the embodiment of the present disclosure, the UE only needs to receive the updated other system information without re-receiving all other system information, and is mitigated. The signaling burden reduces the overhead of system signaling.

FIG. 3 is a flowchart of another method for acquiring system information according to an exemplary embodiment of the present disclosure. The method is applied to a base station. As shown in FIG. 3, the method may include:

Step 301: Send indication information to the UE, where the indication information includes an identifier of the first other SI, where the first other SI is any other SI in the base station.

Step 302: Receive a receiving request sent by the UE, where the receiving request is sent by the UE after determining that the indication information indicates that the first other SI has been updated, and the receiving request includes: an identifier of the first other SI.

Step 303: Send update information to the UE according to the receiving request, where the update information includes the updated first other SI.

In summary, the method for acquiring system information provided by the embodiment of the present disclosure, after the first other SI is updated, the base station may send indication information to the UE, to prompt the UE that the first other SI has been updated, and then receive the reception sent by the UE. Requesting, and according to the identifier of the first other SI carried in the receiving request, to the UE The update information including the updated first other SI is sent, and the base station only needs to transmit the updated other system information to the UE without resending all other system information, which reduces the signaling burden and reduces the overhead of system signaling.

FIG. 4-1 is a flowchart of still another method for acquiring system information according to an exemplary embodiment of the present disclosure, which may be applied to the implementation environment shown in FIG. 1 , as shown in FIG. 4-1 , the method may be include:

Step 401: When the first other SI is updated, the base station generates indication information, where the indication information includes an identifier of the first other SI, where the first other SI is any other SI in the base station.

Optionally, the indication information may be a minimum SI or a paging instruction.

In one aspect, when the indication information is the minimum SI, the minimum SI may include the identifiers of all other SIs in the base station and the latest indication values of all other SIs. It should be noted that the identifier value is used to indicate to the UE whether other SIs are updated. After a certain other SI update, the identifier values corresponding to the other SIs are also updated, and are used to prompt the UE that the other SIs have been updated. Each of the other SIs may be assigned an initial flag value, which may be zero.

The indication value of the first other SI is the first indication value, and the indication value of the first other SI is updated after the first other SI update, and the updated indication value is different from the pre-update indication value of the first other SI.

Correspondingly, the process of generating indication information by the base station may include:

After the first other SI update, the base station updates the indication value of the first other SI to obtain the first indication value, so that the first indication value is different from the pre-update indication value of the first other SI, and then the base station generates a minimum SI, the minimum SI. The identifier of all other SIs in the base station and the latest indication values of all other SIs are included, wherein the indication value of the first other SI is the first indication value.

In an actual application, when the base station updates the identifier value of the first other SI after the first other SI update, the base station may ensure that the updated first flag value is different from the second flag value of the previous time. All the values of the labels before the other SIs are different, and the embodiments of the present disclosure do not limit this.

Optionally, the update rule of the first other SI may be: the first other SI is updated at the current moment, after the first other SI update, the base station adds n to the second indicator value to obtain the first indicator value, where n is greater than or Equal to 1. It should be noted that the identifier values of other SIs are all integers.

For example, the identifiers of other SIs may be SI1, SI2, SI3, etc., respectively, and the identifier of the first other SI is SI1, and the second identifier value of the first other SI at the previous moment is 5, when n is equal to 1, the first The marked value is 6.

On the other hand, when the indication information is paging signaling, correspondingly, the base station generates the indication information. Can include:

The base station generates paging signaling, where the paging signaling carries the identifier of the updated other SI, where the updated other SI includes the first other SI.

For example, after the first other SI update, when the base station sends the paging signaling to the UE, the base station may carry the identifier of the first other SI, for example, SI1.

It should be noted that the core network may send a paging instruction to a UE that is in an idle state, a connected state, or an inactive state. Therefore, the UE may receive in different states. The paging command sent to the base station, so the base station can indicate the first other SI update by the paging instruction.

Optionally, the paging signaling may be used to send a call request to the UE in the idle state, and notify the UE to start receiving the earthquake tsunami warning information, in addition to notifying the UE of the system information update (English: Earthquake and tsunami warning information) Abbreviation: ETWS) Notifies and informs the UE to start receiving commercial mobile early warning service (CMAS) notifications, etc. This embodiment of the present disclosure does not limit this.

Step 402: The base station sends indication information to the UE.

Optionally, when the indication information is the minimum SI, the base station needs to periodically send the minimum SI to perform data transmission with the UE, and may send the minimum SI to indicate the first other SI update of the UE, without additionally sending the indication information; When the information is a paging command, the base station may send the paging command carrying the identifier of the first other SI to the UE after the first other SI update, and may immediately prompt the UE that the first other SI has been updated, and the real-time performance is high.

Step 403: When the UE needs to use the first other SI, the UE determines, according to the indication information, whether the first other SI has been updated.

It should be noted that when the UE does not need to use the first other SI, it may not be determined whether the first other SI is updated. If the UE does not need to use the first other SI, the UE does not use the information carried in the first other SI even if the first other SI is updated. Therefore, the information carried in the first other SI is for the UE. Useless information, when the UE does not need to use the first other SI, it is not necessary to determine whether the first other SI has been updated, and thus it is not necessary to obtain the updated first other SI, thereby reducing unnecessary transmission of system information between the base station and the UE, and reducing the transmission. The signaling burden reduces the overhead of system signaling.

Optionally, when the indication information is the minimum SI, the process of determining, by the UE, whether the first other SI has been updated according to the indication information, as shown in FIG. 4-2, may include:

Step 4031: Obtain a second identifier value of the first other SI in the minimum SI acquired by the UE.

For example, referring to the example in step 401, it is assumed that the second identifier of the first other SI acquired by the UE is the identifier value acquired by the UE at a time, and the second identifier value may be 5.

Step 4032a compares the first indication value with the second indication value.

For example, referring to the example in step 401, the first indication value acquired by the current time UE may be 6, and the first indication value is compared with the second indication value.

Step 4033a: When the first indication value is different from the second indication value, determining that the first other SI has been updated.

Step 4034a, when the first indication value is the same as the second indication value, determining that the first other SI is not updated.

Optionally, when the indication information is a paging instruction, the process of determining, by the UE, whether the first other SI is updated according to the indication information, as shown in FIG. 4-3, may include:

Step 4031b: Detect whether the paging signaling carries the identifier of the first other SI.

Optionally, after receiving the paging signaling, the UE may detect whether the paging signaling carries the identifier of the first other SI. For example, refer to the example in step 401, that is, the UE detects the paging signaling. Whether the identifier SI1 is carried in the middle.

Step 4032b: When the paging signaling carries the identifier of the first other SI, it is determined that the first other SI has been updated.

For example, when the identifier SI1 is carried in the paging signaling, it is determined that the first other SI has been updated.

Step 4033b: When the paging signaling does not carry the identifier of the first other SI, it is determined that the first other SI is not updated.

For example, when the identifier SI1 is not carried in the paging signaling, it is determined that the first other SI is not updated.

Step 404: When it is determined that the first other SI has been updated, the UE sends a receiving request to the base station.

Optionally, when the UE needs to use the updated first other SI, the receiving request may be sent to the base station, where the receiving request includes an identifier of the first other SI, and is used to request the updated first other SI from the base station.

It should be noted that when it is determined that the first other SI is not updated, the UE does not need to change the first other SI, so there is no need to send a receiving request to the base station.

Step 405: The base station generates update information according to the receiving request, where the update information includes the updated first other SI.

Optionally, after receiving the receiving request sent by the UE, the base station may obtain the updated first other SI according to the identifier of the first other SI in the receiving request, and generate update information.

Step 406: The base station sends update information to the UE.

It should be noted that the base station sends the update information to the UE, which may be the time when the update information is generated. The update information is carried in the minimum SI that is periodically sent, and is not limited in this embodiment of the present disclosure.

Step 407: The UE updates the first other SI according to the update information.

Optionally, after receiving the update information, the UE may update the first other SI, and after updating the first other SI, use the information carried in the first other SI.

In summary, in the method for acquiring system information provided by the embodiment of the present disclosure, the UE may receive the indication information sent by the base station, and after determining the first other SI update according to the indication information, send the identifier including the first other SI to the base station. Receiving the request and receiving the updated first other SI sent by the base station, in the embodiment of the present disclosure, the UE only needs to receive the updated other system information without re-receiving all other system information, and is mitigated. The signaling burden reduces the overhead of system signaling.

It should be noted that the sequence of the steps of the method for acquiring system information provided by the embodiment of the present invention may be appropriately adjusted, and the steps may also be correspondingly increased or decreased according to the situation, and any technical person skilled in the art may disclose the technical scope disclosed by the present invention. Within the scope of the present invention, the method of change can be easily conceived, and therefore will not be described again.
