Description

System information transmission method, device, network equipment and terminal

The present invention belongs to the field of communication technology, and particularly relates to a method, a device, a network device, and a terminal for transmitting system information.

In the new-generation wireless communication system (5G or air interface NR system), the network bandwidth can be much larger than the terminal transmission bandwidth. Therefore, the concept of part bandwidth (BWP) is introduced, and the carrier bandwidth of a cell can be divided. For multiple BWP. The base station can configure multiple BWPs for the terminal UE through dedicated signaling, and the Rel-15 version UE can only have one activated uplink BWP and one activated downlink BWP. The startup BWP may be different from the initial BWP that can broadcast system information periodically.

About BWP:

In traditional LTE systems, the cell carrier bandwidth at the network side is less than or equal to the terminal receiving bandwidth of 20 MHz. Therefore, the network side always configures the total uplink and downlink bandwidth of the cell to the terminal, and the terminal can work on the entire cell carrier bandwidth. . In the NR system, the network-side carrier bandwidth can be as high as 400MHz, which is far greater than the receiving capability of the terminal. Therefore, the concept of BWP is introduced, that is, dividing the large bandwidth on the network side into multiple partial bandwidth BWPs, allocating one or more BWPs to the terminal, and starting the partially configured BWP for uplink and downlink transmission for the terminal, and the started downlink BWP Called active DL BWP, the activated uplink BWP is called active UL BWP. In the R15 version, for a terminal, only one DL BWP and one UL BWP can be started at a time. Non-started BWPs cannot perform uplink and downlink signaling and data transmission.

Among them, starting BWP can be changed explicitly by the base station using physical layer signaling DCI (Downlink Control Information, downlink control information), or it can be automatically changed to the default (default) BWP through the BWP-Inactivity Timer configured on the network side.

IDLE and inactive UEs obtain system information and paging (paging) messages by listening to the initial BWP, and the network side broadcasts system information on the initial BWP.

In the NR system, system information is divided into community-level system information and regional-level system information. For regional-level system information, multiple base stations gNB can share the same system information configuration. SIB1 can broadcast the system information area ID (area identifier). ) And the value tag (version tag) of each SIB version, the UE can store and manage system information according to the area ID and value tag. For the updated system information, the UE can check the corresponding area ID and value tag. If the UE has stored the version of the SIB, it can avoid re-acquiring the system information.

The system information transmission method provided by the embodiment of the present invention is further described below in combination with network equipment and both sides of the terminal.

In view of the above technical problems, an embodiment of the present invention provides a system information transmission method, including: the network side sends system information to the UE through dedicated signaling, which may be based on the UE's request, and the network side sends the corresponding system information to the UE according to the requested information. The UE may also be the network side to actively send system information to the UE at a special time or for a specific UE. For example, the network The road side decides to update the system information in the next system information modification period, and then sends the updated system information to the UE through dedicated signaling during the system information modification period. The UE stores the corresponding system information and takes the updated system information into effect in the next modification period. , Or send updated system information to the UE at the boundary of the next system information modification cycle, and the UE stores the corresponding system information when it receives the corresponding system information, and immediately takes effect on the corresponding system information or after the network-side response message is successfully sent; or the network The updated system information can be sent to the UE at any time. The UE takes effect after receiving it, or it takes effect after successfully sending a network-side response message. For the PWS-related notification information sent by the network, the UE takes effect immediately when it receives system information containing the PWS.

The following describes the two cases where the network side actively sends system information to the terminal through dedicated signaling and the network side receives a request from the terminal and then sends system information to the terminal through dedicated signaling.

Case 1: The network side decides not to send a system information-specific signaling message to the UE based on the UE request. As shown in Figure 3.

The network side sends the paging DCI to notify the connected UE system information update, ETWS (Earthquake and Tsunami Warning System) or CMAS (Commercial Mobile Alert Service) notification, and then sends the updated information through dedicated signaling. System information, ETWS or CMAS messages, or directly notify the UE to perform system information update or PWS notification through system information dedicated signaling.

For the update of the system information, the UE stores the currently used system information. The UE only needs to obtain the updated specific system information, such as MIB (Master Information Block), SIB1 (System Information Block 1, System Message Block). 1), SIB2 (System Information Block 2, System Information Block 2) or SI that contains changes to the SIB, there is no need to obtain all System information, and the network side can determine the specific system message SI or system message block SIB that it updates (SI, SIB can be considered as the subtleness of network scheduling system information, SI can be multiple SIBs), such as the main block MIB , SIB1, SIB2, or SI with changed SIBs, or even updated specific IE (Information element, message element), so the UE can obtain updated system information through dedicated signaling as follows:

(1) The network sends the updated system information to the UE through the system information dedicated signaling, which includes one or more of the following:-system information configuration;-system information version information, such as area ID and / or value tag ;-Explicit or implicit system information update instructions; where the system information configuration can be configured based on the delta configuration (variable configuration) of the currently applied system information, that is, it contains only the updated MIB (Master Information Block, master block) ) Or the IE updated in the SIB or SI, for the IE that has not been updated, the dedicated signaling message may not be carried, and the network side and the UE preset the default IE to use the previous configuration.

It can also be a full configuration (full configuration) method, which contains all the configuration information elements of a complete system information unit. The system information unit can be SIB, MIB or SI. For the default IE, the network side and the UE consider that the IE is not configured. Then the IE is processed according to the default processing method of the IE, such as deleting the configuration or using a preset configuration.

The SIB or SI contained in it can be part of the SIB or SI, such as an updated SIB or SI; or a required SIB (some SIBs that must be used to access the network, such as UE access networks in LTE must obtain MIB, SIB1, and SIB2 ) Or SI, such as SIB1; or all SIBs or SIs.

The system information version information may be version information corresponding to all SIBs, or version information corresponding to some SIBs. The version information can contain only the value tag, or the value tag and area ID.

(2) After the UE receives the system information sent by the network side through dedicated signaling, the system information becomes effective immediately or becomes effective in the next modification cycle.

The dedicated signaling may be a newly defined dedicated message, or an already defined message, such as an RRC connection reconfiguration message.

For example: the network side sends the updated system information, ETWS or CMAS notification message to the UE through dedicated signaling within the system information modification period of the paging DCI sending notification system information update notifications and ETWS and / or CMAS notifications;-if the The dedicated signaling carries the PWS message, and the PWS message takes effect immediately;-If the dedicated signaling is sent in the same system information modification cycle after notifying the system information to update the paging DCI, and carrying the updated system information, the system information will be in the next Effective during the modification cycle.

Or, after the network side sends a notification of system information update notification to the paging DCI, the next system information modification cycle sends the updated system information to the UE through dedicated signaling. Then the UE takes effect immediately after receiving the message.

Or, the system information is sent to the UE based on the network requirements, and the UE takes effect immediately after receiving the system information. For example, the network side does not send a paging DCI to notify the system information update to the UE, and the network side decides to perform After the system information is updated, it sends dedicated signaling to carry the updated system information to the UE, or after the network sends a paging DCI notification, during the next system information modification cycle, due to scheduling and other reasons, the network sends the updated information at any time. Dedicated signaling for system information to the UE, or for UEs with special services, such as URLLC (Ultra-Reliable and Low Latency Communications), the network decides to send updated system information to the UE through dedicated signaling , The UE becomes effective immediately after receiving the system information or becomes effective after the network-side response message is successfully sent.

Or, the network sends a system information-specific signaling message, which implicitly or explicitly carries a system update indication. If the message contains a PWS message, it takes effect immediately; otherwise, the UE stores the message for the next system information modification cycle. Make it effective. For example, the network side does not send paging DCI to notify the system information update to the UE. After the network side decides to update the system information, it sends dedicated signaling to carry the updated system information to the UE, or for UEs with special services, such as URLLC (Ultra- Reliable and Low Latency Communications), the network decides to send updated system information to the UE through dedicated signaling. After receiving the system information, the UE stores the updated system information and stores it in the next system information modification cycle. Take effect.

The method can be applied to a UE that cannot receive broadcast system information, such as a connected UE in a BWP that cannot broadcast system information, or a BWP that can broadcast system information is not configured with paging control resources corresponding to obtaining system information or system information notifications, or A connected UE in the search space, or a connected UE in paging DCI that does not send notification of system information modification in the BWP that can broadcast system information, or a UE with special services, such as URLLC service, or special system information messages, such as PWS notification Or MIB message, the network sends the message for the connected UE on the BWP through dedicated signaling. But it is not limited to the above scenarios.

Case two, based on the method requested by the UE, the network side sends a system information-specific signaling message, as shown in FIG. 4.

Since the UE can store different versions of the system information, when the system information version stored by the UE includes a system information version that is about to be updated, the UE can read the updated SI or SIB (updated SIB) without re-reading. Uses the version of the system information that has been stored. Based on the UE request, the overhead of the air interface can be saved. The system information request message sent by the UE to the network side may carry the stored SI or SIB version number. After receiving the request message, the network side may selectively send the system information to the UE according to the system information version stored by the UE. The stored system information of the version to be updated is sent to the UE. For the system information of the stored version to be updated, the network side notifies the UE of the version to be updated.

(1) The UE side sends a system information acquisition request message to the network side. The request message may carry one or more of the following:-Version information of the currently stored system information, such as area ID and / or value tag. The version information may be Contains version information of all SIBs or version information of some SIBs, such as version information of SIBs requested by the UE. The version information contained therein may be all stored version information of the SIB requested by the UE, or storage information of other versions excluding the currently used version;-the requested SIB ID. Among them, MIB and SIB1 can explicitly request the network side to send the corresponding system message through the request message carrying the corresponding ID, or it can be implicitly requested, that is, always request MIB and / or SIB1;-explicit or implicit system information request indication .

(2) The network side sends system information to the UE through dedicated signaling, where the dedicated signaling may include one or more of the following:-system information configuration;-system information version information, such as area ID and / or value tag; where The system information configuration can be configured in a delta configuration mode based on the currently applied system information, that is, it includes only the updated MIB or SIB or the updated IE in the SI. For the default IE network side and the UE, the IE maintains the original configuration.

It can also be a full configuration, that is, all IEs that include a complete MIB or SIB or SI configuration.

The SIB or SI contained therein may be a partial SIB or SI, such as an updated SIB or SI; or a required SIB or SI, such as SIB1; or all SIBs or SIs. After receiving the system information request message, the network side may send MIB and / or SIB1 according to the request message, or decide whether to send MIB or SIB1 based on whether the MIB or SIB1 changes, or always send MIB and / or SIB1.

The system information version information may be version information corresponding to all SIBs stored by the UE, or version information corresponding to some SIBs. The version information can contain only the value tag, or the value tag and area ID.

(3) The UE can initiate a request after receiving the system information update paging DCI, or when the system information is not successfully received, or when the system information is not stored (for example, the UE's initial access only acquired the access network). Necessary system information, but other information such as the configuration information of the neighboring cell is not obtained. If the subsequent UE wants to obtain these system information, Network request), or UEs that include special services, such as URLLC, request from the network side, or other scenarios that require system information, are not limited to the above scenarios.

(4) After the UE receives the system information sent by the network side through dedicated signaling, the system information becomes effective immediately or becomes effective in the next modification cycle.

For example, for a PWS message, the UE should take effect immediately after receiving it. For other system messages, the effective time can be determined based on the time when the paging DCI is sent (for example, the system information and paging DCI sent from the network will be modified in the next cycle, and if it is not the same cycle, it will take effect immediately), or Choose to take effect immediately according to the scenario requested by the UE. For example, the UE requests a lack of SIB messages, or the network does not send a paging DCI. The UE takes effect immediately after receiving.

Example of case 1:

Example 1: Used in the system information update scenario, the next modification cycle takes effect.

‧Send system information update notification scene

(1) The connected UE is a UE with special services, such as URLLC, or a connected UE that cannot receive broadcast system information, such as a UE that is not configured with control resources or search space to acquire broadcast system information, or although configured to acquire a broadcast system Information-controlling UE but the network has not sent a connected state UE or a normal connected state UE notifying the system of paging DCI notification; (2) the network decides to update the system information and sends a paging DCI to notify the UE; (3) the UE receives The paging DCI sent to the network side knows that the network side is about to update the system information in the next modification cycle. Or the UE cannot receive the paging DCI; (4) the network side sends system information to the UE through dedicated information during the system modification period of the sending paging DCI; (5) After receiving the updated system information sent by the network side through dedicated signaling, the UE stores the system information and makes it effective at the next system information modification cycle boundary.

‧Do not send system information update notification scene

The network side may not send paging DCI, but directly send dedicated signaling carrying updated system information to notify the UE to update the system information in the next system information modification cycle; (1) The connected state UE is a UE with special services, such as URLLC, or cannot receive Connected UEs of broadcast system information, for example, UEs that are not configured with control resources or search space to obtain broadcast system information, or UEs that are configured with control resources to obtain broadcast system information, but the network does not send a paging DCI that notifies system information updates Connected UE, or normal connected UE; (2) the network side decides to update system information; (3) the network side sends system information to the UE through dedicated information. The dedicated signaling explicitly carries the system information modification instruction or implicitly carries the system information modification instruction. For example, the signaling can only be used in the system information update scenario; (4) The UE receives the dedicated information from the network side by carrying the system information update instruction. The updated system information sent by the signaling is stored in the system information and becomes effective in the next system information modification cycle boundary.

Example 2: The UE takes effect immediately after receiving system information through dedicated signaling.

‧PWS notification scene

(1) The connected UE works when the BWP is started, and the paging DCI is notified by the PWS, or the paging DCI is not sent; (2) The network side sends the system information dedicated signaling carrying the corresponding PWS message to the UE; (3) The UE receives The system information carrying the PWS message sent by the network takes effect immediately.

‧Non-PWS notification scenario

(1) The connected UE is a UE with special services, such as URLLC, or a connected UE that cannot receive broadcast system information, such as a UE that is not configured with control resources or search space to acquire broadcast system information, or although configured to acquire a broadcast system Information-controlling UE but the network has not sent the connected state UE or the normal connected state UE notifying the system information update of the paging DCI; (2) The network side decides to update the system information, sending the paging DCI to notify the UE or not sending the paging DCI to UE; (3) the network side sends system information to the UE through dedicated information during the corresponding system information modification cycle; (4) the UE receives the updated system information sent by the network side through dedicated signaling, and stores the system information immediately Take effect.

Example three:

Based on the currently used system information, perform delta configuration to send system information; (1) the connected UE works on the startup BWP, which stores the system information and version information used in the current system information modification cycle; (2) the network side decides to update A SIB, for example, IE1 in SIB1 is updated, SIB3 is modified from version 2 to version 1, where IE3 is updated compared to the current version; (3) The network side according to the updated IE assembly system information dedicated signaling message, where the message The corresponding IE in the updated SIB is carried in, for example, IE1 in SIB1 and IE3 in SIB3. And / or the version number of the corresponding SIB. For example, SIB3 uses version 1. The network side sends the message to the UE at the corresponding sending time; (4) The UE receives the system information message sent by the network side.

If the message carries the corresponding version number, and the current version of the SIB is not stored by the UE, the system information is stored in a delta configuration. For example, if SIB3 is updated from version 2 to version 1, the system is stored in version 2. Based on the information, update IE3 and store it as version 1. If the version number carried in the message, the UE already stores the corresponding version of the SIB, the UE may not have to read its corresponding updated IE. The UE will take the updated version of the system information into effect at the corresponding time in the above example 1 and example 2.

If the message does not carry a version number, the UE will update the corresponding IE based on the SIB of the currently used version, for example, update the IE1 of the current version of SIB1 to the value carried in the message, and update the IE3 in SIB3 to the message. The carried value, and the updated system information will take effect at the corresponding times in Example 1 and Example 2 above.

Example 4: Send system information based on full configuration;

(1) The connected UE works on the startup BWP, which stores the system information and version information used in the current system modification cycle;

(2) The network side decides to update a certain SIB, for example, IE1 in SIB1 is updated, SIB3 is changed from version 2 to version 1, and IE3 is updated;

(3.1) The network side assembles the system-specific dedicated signaling message according to the updated SIB or SI, where the message carries the updated SIB or SI, such as SIB1 and SIB3, or the SI existing in SIB1 and SIB3. The message may also carry the version number of the corresponding SIB. For example, SIB3 uses version 1. The network side sends the message to the UE at the corresponding sending times in Example 1 and Example 2. (3.2) The network side assembles the system information-specific signaling message according to the updated SIB or SI, where the message carries all system information (i.e. MIB, SIB1, and other SI), and / or the version number of the corresponding SIB, such as the version numbers of all SIBs. The network side corresponds to the above example 1 and example 2. Send the message to the UE at the time of sending; (3.3) The network side assembles the system-specific dedicated signaling message according to the updated SIB or SI, where the message carries part of the SIB or set (such as MIB, SIB1, and some other SI). The part of the SIB or set may also be an updated SIB or SI in a preset system information set, where the preset set may be a set of system information set according to a service or a system information set according to whether it is necessary to access a network , Or the default system information collection contains all system information. The message can also carry the version number of the corresponding SIB. For example, SIB3 uses version 1 and other SIB version numbers. The network side sends the message to the UE at the corresponding sending moments in the above Example 1 and Example 2.

Operations (3.1), (3.2), and (3.3) are side by side.

(4) The UE receives the system information message sent by the network side: If the message carries the corresponding version number, and the UE does not currently store the version of the SIB, the system information is stored. If the version number carried in the message, the UE already stores the corresponding version of the SIB, the UE may not have to read its corresponding SIB. The UE will take the updated version of the system information into effect at the corresponding time in Example 1 and Example 2 above; if the message does not carry a version number, the UE will store the system information carried in the message, and the corresponding information in Example 1 and Example 2 above The updated system information will be effective at all times.

Example of case two:

Example 1: The UE sends a system information request notification to request the network side to send system information;

(1) The UE decides to request updated system information from the network side; (2) The UE assembles a system information request notification message, where the message can explicitly carry the system information request indication or implicitly carry the indication, for example, the message is only used for requesting The network sends updated system information. The UE sends the message to the network side at the corresponding time. The message can be RRC Layer signaling messages can also be low-level messages; (3) The network side receives the system information request message sent by the UE, assembles the corresponding system information and sends it to the UE through dedicated signaling. The message may carry a corresponding message and / or corresponding version information in a full configuration manner or a delta configuration manner. As described in Example 3 and Example 4 in case 1 above; (4) After receiving the dedicated signaling carrying system information sent by the network side, the UE stores the system information in the delta configuration mode or the full configuration mode, and stores the system information in the corresponding Always take system information into effect. As described in Example 1 and Example 2 in Case 1 above.

Example 2: The UE sends the stored system information version information to request the network side to send the system information;

(1) The UE decides to request updated system information from the network side; (2) The UE assembles a system information request notification message, where the message can carry all version information of all SIBs stored by the current UE or all versions except the currently used version Information; or the corresponding version information stored in the SIB requested by the UE or all version information except the currently used version. For example, the current SIB2 stores version 1 and version 2, the current SIB3 stores version 4 and the currently used version: SIB2 uses version 1 and SIB3 uses version 4, the UE can carry SIB2 version 2, and SIB3 does not need to carry the corresponding version or provide SIB2 storage Version 1 and version 2, SIB3 stores version 4; (3) The network side receives the system information request message sent by the UE, assembles the corresponding system information and sends it to the UE through dedicated signaling. The message carries a version information notification for updating the SIB to notify the UE to use the system information of the corresponding version and / or some system information configuration. For the version of the SIB to be updated soon, the UE does not store the configuration information of the version. The delta configuration mode or full configuration mode provides the corresponding SIB or SI configuration information, as described in Example 3 and Example 4 in Case 1 above. For example, when updating SIB2 uses version 2 and SIB3 uses version 1, the dedicated signaling message needs to carry the system information of version 1 of SIB3 without carrying the system information of SIB2. For MIB and SIB1, the network side can use the full configuration or delta configuration to assemble the corresponding system information configuration into the message to the UE. Carry the information about the new version of the SIB used to notify the UE. As in the above example, you need to carry the notification information used to notify SIB2 that version 2 is used, and SIB3 uses the version 1 notification information. For the SIB that has not changed, the network side can carry the version information of the SIB, or it can continue to use the previous version information by default; (4) After receiving the dedicated signaling carrying the system information sent by the network side, the UE performs the delta The configuration method or the full configuration method stores system information and stores corresponding version information, and the system information of the version notified in the message takes effect at the corresponding moment. As described in Example 3 and Example 4 in case 1 above.

Example 3: The UE sends the requested SIB ID to request the network side to send system information;

(1) The UE decides to request updated system information from the network side; (2) The UE assembles a system information request notification message, where the message can carry the SIB ID requested by the UE, and for MIB and SIB1, it can carry the corresponding ID or not. The ID defaults to always request MIB or SIB; or carry all version information stored by the UE corresponding to the requested SIB or all version information except the currently used version. For example, requesting SIB2 and SIB3, the current SIB2 stores version 1 and version 2, the current SIB3 stores version 4, and the currently used version: SIB2 uses version 1, SIB3 uses version 4, the UE can carry SIB2 version 2, and SIB3 need not carry the corresponding version Or, SIB2 stores version 1 and version 2, and SIB3 stores version 4; (3) The network side receives the system information request message sent by the UE, and assembles the corresponding system information. The message is sent to the UE through dedicated signaling. This message carries the requested SIB or SI configuration message. This message may also carry the version information of the corresponding SIB, or the message carries the version message used by the request message, and the SIB or SI configuration message of the SIB version not stored by the UE. . The above SIB or SI or MIB configuration message may be provided to the UE based on delta configuration or full configuration, as described in Example 3 and Example 4 in case 1 above. For example, the request message carries the version information currently requested by the UE for the SIB. For the version used by the updated SIB, the UE has not stored the configuration information of the version of the SIB. The network will provide the configuration information of the SIB. For the version used by the SIB, the UE has already stored the configuration information of the SIB in this version, so the network side does not need to provide the detailed configuration information of the SIB, and only needs to notify the UE to use the corresponding version. For example, when updating SIB2 uses version 2 and SIB3 uses version 1, the dedicated signaling message needs to carry the system information of version 1 of SIB3 without carrying the system information of SIB2. It is required to carry the notification information that the SIB2 uses version 2 and the SIB3 uses version 1 notification information. For the SIB that has not changed, the network side can carry the version information of the SIB, or it can continue to use the previous version information by default; (4) After receiving the dedicated signaling carrying the system information sent by the network side, the UE shall follow the delta The configuration mode or the full configuration mode stores the system information, and stores the corresponding version information, and the system information of the version notified in the message takes effect at the corresponding moment, as described in the above case 1, example 3 and example 4.

Example four: the moment when the UE sends a system information request;

The UE sends a system information request message to the network side to request MIB to obtain the system information. (3.3) The network side starts the BWP broadcast system information on the UE. The UE fails to receive the system information. The UE sends a system information request message to the network side. The request was unsuccessful.
