[0001] The present disclosure relates to the field of communication technologies, and in particular, to a method and apparatus for notifying system message updates, an electronic device, and a computer-readable storage medium. Background Art

[0002] When a terminal accesses a cell, it needs to obtain the system information of the cell. In the related art, system messages can be carried in the MIB (Main Information Block) and multiple SIBs (System Information Blocks).

[0003] In wireless communication, the channels used for information transmission can be subdivided into physical channels, transport channels, and logical channels. Among them, the physical channel is the channel for actual information transmission at the physical layer, the transport channel is the channel between the physical layer and the MAC (Medium Access Control) sublayer, and the logical channel is the channel between the MAC sublayer and the RLC (Radio Link Control) sublayer.

[0004] On the logical channel, both the MIB and the SIB are carried by the BCCH (Broadcast Control Channel). On the transport channel and the physical channel, the channels carrying the MIB and the SIB are different. Among them, the MIB is carried by the BCH (Broadcast Channel) on the transport channel and mapped to the physical channel PBCH (Physical Broadcast Channel); the SIB is carried by the DL-SCH (Downlink Shared Channel) on the transport channel and mapped to the physical channel PDSCH (Physical Downlink Shared Channel).

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present disclosure with reference to the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only some embodiments of the present disclosure, rather than all embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present disclosure.

[0031] In the related art, system information may be carried in the MIB or SIB, where the SIB may include SIB1 and other SIBs.

[0032] For the SIB carried by the PDSCH, the base station schedules it through the DCI of the PDCCH. That is to say, the terminal can first receive the DCI carried by the PDCCH, and then receive the SIB carried by the PDSCH according to the indication of the DCI, and obtain the system information.

[0033] In one embodiment, in order to save the power consumption of the terminal, the system information may be carried on other channels except the above-mentioned channels. For example, a part of the system information may be directly carried in the DCI originally used to schedule the SIB. Thus, the terminal does not need to first receive the DCI and then receive the SIB according to the scheduling of the DCI, but directly receives the system information in the DCI, thereby saving the power consumption and improving the information reception efficiency.

[0034] For the system information carried by the MIB and SIB, if the system information is updated, the base station may send a DCI (Downlink Control Information) carrying a short message to the terminal to indicate the update of the logical BCCH channel. Since the BCCH channel is used to carry the MIB or SIB, the terminal can determine that the system information carried by the MIB or SIB is updated and receive the updated system information according to the actual situation.

[0035] However, for the system information carried on other channels except the BCH and DL-SCH, if the system information is updated, the terminal cannot know either, which may affect normal communication.

[0036] In view of this, the embodiments of the present disclosure propose a method and apparatus for notifying system information update to solve the above technical problems.

[0037] Figure 1 FIG. is a schematic flowchart of a method for notifying system information update according to an embodiment of the present disclosure. The method for notifying system information update shown in this embodiment may be applicable to a base station, and the base station includes but is not limited to 4G base stations, 5G base stations, and 6G base stations. The base station may communicate with a terminal serving as a user equipment, and the terminal includes but is not limited to electronic devices such as mobile phones, tablet computers, wearable devices, sensors, and Internet of Things devices. In one embodiment, the terminal may be the terminal applicable to the method for notifying system information update in any subsequent embodiment.

[0038] As Figure 1 shown, the method for notifying system information update may include the following steps:

[0039] In step S101, in response to determining an update of the first type of system message, an update notification is sent to the terminal.

[0040] Wherein, the first type of system message is a system message carried by a channel other than the broadcast channel BCH and the downlink shared channel DL-SCH.

[0041] In one embodiment, when the base station determines an update of the first type of system message, it may send an update notification to the terminal.

[0042] In one embodiment, when the terminal receives the update notification, it may determine that the system message has changed and perform a response operation. For example, the terminal may receive the updated system message and update the local configuration, etc.

[0043] In one embodiment, the first type of system message is a system message carried by a channel other than the broadcast channel BCH and the downlink shared channel DL-SCH, or, in other words, the first type of system message is a system message carried by a channel other than the PBCH and the PDSCH.

[0044] It should be noted that the system messages carried in the MIB and SIB in the related art are carried by the BCH and DL-SCH channels on the transport channel, are carried by the BCCH on the logical channel, and are carried by the PBCH and PDSCH on the physical channel.

[0045] According to the above embodiments, for the system message carried by a channel other than the BCH and DL-SCH, if the system message is updated, the base station can also timely send an update notification to the terminal, so that the terminal can timely learn of the system message update and receive the updated system message according to actual needs, ensuring normal communication.

[0046] In one embodiment, the other channel is the physical downlink control channel PDCCH. Wherein, in one example, the PDCCH may be the control signaling for scheduling the SIB, and the SIB may be SIB1 or other SIBs.

[0047] Based on this, in one embodiment, the terminal may receive the first type of system message on the PDCCH, without receiving it in the PDSCH according to the indication of the DCI, improving the information reception efficiency and being beneficial to energy consumption saving.

[0048] In one embodiment, the first type of system message is carried in the downlink control information DCI carried by the PDCCH for scheduling the system information block SIB.

[0049] Based on this, in one embodiment, for the DCI of this scheduled SIB, the terminal generally also needs to receive it. Therefore, the base station does not need to give the terminal an additional indication, but carries the first type of system message based on the original information, which helps to simplify the process and save signaling overhead. In addition, if the DCI carries both the first type of system message and the scheduling message of the SIB, the terminal can obtain multiple messages through one reception, thereby further improving the information reception efficiency.

[0050] In one embodiment, for the above-mentioned first type of system message, the updated first type of system message is generally also transmitted through other channels. For example, for the first type of system message carried by the PDCCH, if there is an update, after the base station sends an update notification to the terminal, it can also send the updated first type of system message to the terminal through the PDCCH; for the first type of system message carried in the DCI used to schedule the SIB carried by the PDCCH, if there is an update, the updated first type of system message can still be carried by the DCI. Thus, the terminal can also receive the updated first type of system message efficiently and with low energy consumption.

[0051] In one embodiment, the base station can send the first type of system message for all terminals in a manner carried by other channels other than the above-mentioned broadcast channel BCH and downlink shared channel DL-SCH, that is, part of the system message is carried by the MIB or SIB in the related technology, and part of the system message is carried as the first type of system message through other channels.

[0052] In one embodiment, the base station can also only target specific terminals. For example, it can be for Redcap (Reduced capability) terminals, or it can also be for 1RX single-reception terminals among Redcap terminals, and adopt the above-mentioned manner carried by other channels other than the broadcast channel BCH and downlink shared channel DL-SCH to carry part of the system message; while for other terminals, only adopt the manner of carrying all system messages by the MIB or SIB in the related technology. Thus, the energy consumption of this specific terminal can be saved in a targeted manner.

[0053] In one embodiment, the base station may also use a method other than the above-mentioned broadcast channel BCH and downlink shared channel DL-SCH to carry specific system messages. For example, for the information on whether a terminal is barred in a cell, the base station may use it as a type-1 system message and carry it through a channel other than the broadcast channel BCH and the downlink shared channel DL-SCH; for example, for the information on whether a terminal is allowed to reselect a co-frequency cell after being barred in a cell, the base station may use it as a type-1 system message and carry it through a channel other than the broadcast channel BCH and the downlink shared channel DL-SCH. For other system messages, as type-2 system messages, they are carried by using MIB or SIB in related technologies.

[0054] In one embodiment, the type-1 system message is used to indicate the information on the access restriction of a specific terminal in the cell, that is, the base station may also carry a specific system message for a specific terminal through a channel other than the broadcast channel BCH and the downlink shared channel DL-SCH.

[0055] It should be noted that the above terminal types and system message types are only illustrative and not specific limitations. In actual applications, the base station may also determine how to send system messages to the terminal according to the actual situation, and this embodiment does not make any limitations.

[0056] In one embodiment, the base station sends an update notification to the terminal, including: sending a short message to the terminal, and the short message is used to indicate the DCI update.

[0057] Wherein, the DCI may be a DCI for scheduling SIB. In one embodiment, since the type-1 system message is carried in the DCI for scheduling SIB, if the short message indicates the update of the DCI, the terminal can determine the update of the type-1 system message.

[0058] It should be noted that in related technologies, short messages are only used to indicate BCCH updates and cannot be used to indicate DCI updates. According to the above embodiment, short messages have a new function of indicating the update of the DCI for scheduling SIB. Thus, after receiving the short message, the terminal can determine the update of the type-1 system message.

[0059] For example, if a bit in the short message is set to 1, it can indicate a BCCH or DCI scheduling SIB modification other than SIB6, SIB7, and SIB8 (indication of a BCCH or DCI scheduling SIB modification other than SIB6, SIB7 and SIB8).

[0060] In one embodiment, the first type of system message is carried on a logical channel by a broadcast control channel BCCH; the BCCH is mapped to a DCI carried by a PDCCH for scheduling a DL-SCH.

[0061] In one embodiment, an SIB is carried on a transport channel by a DL-SCH, and the DCI for scheduling the DL-SCH can also be referred to as the DCI for scheduling the SIB.

[0062] It should be noted that in the related art, a BCCH can be mapped to a BCH for carrying an MIB and a DL-SCH for carrying an SIB, but cannot be mapped to a PDCCH. According to the above embodiment, the BCCH is extended to be able to be mapped to a DCI carried by a PDCCH for scheduling a DL-SCH.

[0063] That is to say, the first type of system message carried by the PDCCH channel also belongs to the BCCH on the logical channel. Thus, the short message used to indicate a BCCH update in the related art can also indicate an update of the first type of system message. According to the above embodiment, there is no need to update the definition of the short message, and the short message in the related art can still be used to indicate an update of the first type of system message, enabling the terminal to timely learn of the update of the first type of system message and ensuring normal communication.

[0064] In one embodiment, mapping the BCCH to a DCI for scheduling a DL-SCH (BCCH can be mapped to DCI scheduling DL-SCH) can add an RRC message on the BCCH logical channel, and the RRC message is carried in the DCI on the physical channel.

[0065] For example, an RRC message BCCH-DCI-Message can be defined, and the BCCH-DCI-Message is an RRC message sent from the network to the UE through the DCI on the BCCH logical channel. For example, the format of the BCCH-DCI-Message can be as follows:

[0066]

[0067] In one embodiment, the RRC message passes through the PDCP (Packet Data Convergence Protocol) layer, the MAC layer, and reaches the physical layer PHY, so that the bits in the RRC message can be mapped to the DCI.

[0068] As described above, the BCCH is mapped to the DCI carried by the PDCCH for scheduling the DL-SCH, and the format of the DCI can also have various forms.

[0069] In one embodiment, the DCI can be a format 1_0 with cyclic redundancy check CRC scrambled by the system information radio network temporary identity SI-RNTI (i.e., DCI format 1_0 with CRC scrambled by SI-RNTI). Based on this, in one embodiment, the first type of system message can be carried in the reserved bit positions of the DCI.

[0070] For example, the following information is transmitted through DCI format 1_0 with CRC scrambled by SI-RNTI:

[0071] – Frequency domain resource allocation where is the size of the initial downlink bandwidth part

[0072] – Time domain resource assignment – 4-bit defined in Subclause 5.1.2.1 of [6, TS38.214]

[0073] [- VRB-to-PRB mapping – 1-bit defined according to Table 7.3.1.1.2-33]

[0074] – Modulation and coding scheme – 5-bit defined in Subclause 5.1.3 of [6, TS38.214], using Table 5.1.3.1-1

[0075] – Redundancy version – 2-bit defined in Table 7.3.1.1.1-2

[0076] – Reserved bits –

[16] -bit

[0077] Among them, the above reserved bits can be used to carry the first type of system message.

[0078] Thus, without affecting the original scheduling information, the DCI can also be used to transmit the first type of system message, thereby improving the information transmission efficiency and reducing the signaling overhead.

[0079] In one embodiment, the DCI can be a specified format with cyclic redundancy check (CRC) scrambled by the system message radio network temporary identifier (SI-RNTI) (i.e., DCI format 1_0' with CRC scrambled by SI-RNTI), where the specified format 1_0' is dedicated to carrying the first type of system message.

[0080] Thus, after receiving the DCI of the specified format, the terminal can determine that the DCI is used to carry the first type of system message, ensuring the reliability of information transmission.

[0081] In one embodiment, the DCI can be a specified format with cyclic redundancy check (CRC) scrambled by a specified radio network temporary identifier (RNTI) (i.e., DCI format 1_0 with CRC scrambled by SI-RNTI’), where the specified radio network temporary identifier SI-RNTI’ is dedicated to scrambling the DCI.

[0082] The above specified DCI format and specified radio network temporary identifier SI-RNTI can be combined and applied, that is, both the specified DCI format and the specified radio network temporary identifier SI-RNT are introduced to carry the first type of system message.

[0083] In one embodiment, for the system message carried by the BCH or DL-SCH, that is, the system message carried in the MIB or SIB, if there is an update, the base station can also send an update notification to the terminal. The following is combined with Figure 2 for illustration.

[0084] Figure 2 is a schematic flowchart of another method for notifying system message update according to an embodiment of the present disclosure. As Figure 2 shown, the method further includes:

[0085] In step S201, in response to determining that the second type of system message is updated, send the update notification to the terminal.

[0086] Among them, the second type of system message is the system message carried by the BCH or DL-SCH.

[0087] In one embodiment, in addition to determining the update of the first type of system message, when the base station determines the update of the second type of system message, it may also send an update notification to the terminal.

[0088] It should be noted that the second type of system message carried by the BCH or DL-SCH is the system message carried in the MIB and SIB in the related art.

[0089] In one embodiment, for the convenience of the terminal to distinguish, the base station may also send indication information to the terminal, where the indication information is used to indicate the update of at least one of the first type of system message and the second type of system message.

[0090] In one embodiment, the indication information sent by the base station may indicate the update of the first type of system message, or indicate the update of the second type of system message, or indicate the update of both the first type and the second type of system message.

[0091] For example, the indication information may be different identifiers, such as including several bits. When the indication information is the first identifier (for example, "01"), it may indicate the update of the first type of system message; when the indication information is the first identifier (for example, "10"), it may indicate the update of the second type of system message; when the indication information is the third identifier (for example, "11"), it may indicate the update of both the first type and the second type of system message.

[0092] In one embodiment, the indication information sent by the base station may be carried in various ways.

[0093] In one example, the base station may send a power saving signal to the terminal, and the indication information is carried in the power saving signal.

[0094] For example, the power saving signal may be a WUS (wake up signal). In the related art, the terminal can use the WUS to indicate that the terminal listens for paging DCI. That is, if the terminal detects the WUS, it listens for the subsequent paging DCI corresponding to the WUS; if it does not detect the WUS, it does not need to listen for the paging DCI corresponding to the WUS, so that the terminal can save energy consumption.

[0095] According to the above embodiments, the base station carries the indication information in the power saving signal without the need to add a new transmission signal, reducing the signaling overhead. At the same time, after receiving the indication information, the terminal can determine whether to listen for the subsequent DCI according to actual needs, thereby saving energy consumption.

[0096] In one example, the base station may send paging DCI to the terminal, and the indication information is carried in the paging DCI.

[0097] In one example, the updated first type of system message is also carried in the paging DCI. For example, for a paging DCI, the base station may carry indication information in the first several bit positions of the paging DCI, and carry the updated first type of system message in the subsequent several bit positions.

[0098] In one example, the updated first type of system message is also carried in the power saving signal. For example, for a power saving signal in the format of PDCCH, the base station may carry indication information in the first several bit positions of the power saving signal, and carry the updated first type of system message in the subsequent several bit positions.

[0099] According to the above embodiments, the terminal can continuously receive update notifications and the updated first type of system message without having to wake up multiple times to receive them separately, which is beneficial for saving energy consumption.

[0100] Figure 3 FIG. is a schematic flowchart of a method for notifying system message update according to an embodiment of the present disclosure. The method for notifying system message update shown in this embodiment can be applied to a terminal, and the terminal includes but is not limited to electronic devices such as mobile phones, tablet computers, wearable devices, sensors, and Internet of Things devices. The terminal can communicate with a base station as a user equipment, and the base station includes but is not limited to 4G base stations, 5G base stations, and 6G base stations. In one embodiment, the base station may be the base station applicable to the method for notifying system message update described in any of the above embodiments.

[0101] As Figure 3 shown, the method for notifying system message update may include the following steps:

[0102] In step S301, in response to receiving an update notification sent by the base station, determine that the first type of system message is updated.

[0103] Wherein, the first type of system message is a system message carried by a channel other than the broadcast channel BCH and the downlink shared channel DL-SCH.

[0104] In one embodiment, when the base station determines that the first type of system message is updated, it may send an update notification to the terminal. Based on this, when the terminal receives the update notification, it can determine that the system message has changed and perform corresponding operations. For example, the terminal can receive the updated system message and update the local configuration, etc.

[0105] According to the above embodiments, for system messages carried by channels other than BCH and DL-SCH, if the system messages are updated, the base station can also send an update notification to the terminal in a timely manner, so that the terminal can timely learn of the system message update and receive the updated system message according to actual requirements, ensuring normal communication.

[0106] In one embodiment, the update notification is indicated by a short message sent by the base station.

[0107] In one example, the base station can carry the first type of system message in the DCI for scheduling SIB. At the same time, the base station adds a function for the short message to indicate the update of the DCI for scheduling SIB. Thus, after receiving the short message, the terminal can determine that the first type of system message is updated.

[0108] In one example, the base station maps the BCCH that was only mapped to BCH and DL-SCH in the related art to the DCI for scheduling DL-SCH carried by the PDCCH. Thus, the short message used to indicate the BCCH update in the related art can also indicate the update of the first type of system message.

[0109] In one embodiment, the short message can indicate the update of both the first type of system message and the second type of system message. Thus, the base station can also send indication information to the terminal, so that the terminal can distinguish which type of system message update it is according to the indication information.

[0110] Based on this, in one embodiment, determining that there is an update to the first type of system message includes:

[0111] Receiving the indication information sent by the base station, where the indication information is used to indicate the update of at least one of the first type of system message and the second type of system message; where the second type of system message is the system message carried by BCH or DL-SCH;

[0112] Based on the indication information, determining that the first type of system message is updated.

[0113] Alternatively, in one example, the terminal can also determine the update of the second type of system message based on the indication information; or the terminal can also determine that both the first type and the second type of system message are updated based on the indication information.

[0114] For example, the indication information may include different identifiers. The terminal determines the meanings represented by different identifiers according to pre - negotiation with the base station or according to protocol regulations, and thus determines which specific system message is updated according to the indication information. For example: when the indication information is the first identifier (for example, "01"), it may indicate the update of the first type of system message; when the indication information is the first identifier (for example, "10"), it may indicate the update of the second type of system message; when the indication information is the third identifier (for example, "11"), it may indicate the update of both the first type and the second type of system messages.

[0115] In one embodiment, the indication information sent by the base station can be carried in multiple ways.

[0116] In one example, the base station can send a power - saving signal to the terminal, and the indication information is carried in the power - saving signal.

[0117] Based on this, in one example, the terminal can receive the power - saving signal sent by the base station; the indication information is carried in the power - saving signal.

[0118] In one example, the base station can send paging DCI to the terminal, and the indication information is carried in the paging DCI.

[0119] Based on this, in one example, receive the paging DCI sent by the base station; the indication information is carried in the paging DCI.

[0120] In one example, receive the paging DCI sent by the base station, and the updated first - type system message is also carried in the paging DCI.

[0121] In one example, receive the power - saving signal sent by the base station, and the updated first - type system message is also carried in the power - saving signal.

[0122] In one embodiment, after the terminal determines that the first - type system message is updated, it can also receive the updated first - type system message on the other channel. Thus, the terminal can perform corresponding operations according to the updated first - type system message. For example, when it is determined that access to the cell is prohibited, it can switch to other cells, etc., to ensure normal communication.

[0123] Corresponding to the foregoing embodiments of the method for notifying system message update, the present disclosure also provides embodiments of a device for notifying system message update.

[0124] Figure 4FIG. 0 is a schematic block diagram of a notification device for system message update according to an embodiment of the present disclosure. The notification device for system message update shown in this embodiment can be applied to a base station, and the base station includes but is not limited to 4G base stations, 5G base stations, and 6G base stations. The base station can communicate with a terminal serving as a user equipment, and the terminal includes but is not limited to electronic devices such as mobile phones, tablet computers, wearable devices, sensors, and Internet of Things devices. In one embodiment, the terminal can be the terminal applicable to the notification device for system message update described in any subsequent embodiment.

[0125] As Figure 4 shown, the notification device for system message update may include:

[0126] A first notification sending module 401, configured to send an update notification to a terminal in response to determining an update of a first type of system message; wherein, the first type of system message is a system message carried by a channel other than a broadcast channel BCH and a downlink shared channel DL-SCH.

[0127] In one embodiment, the other channel is a physical downlink control channel PDCCH.

[0128] In one embodiment, the first type of system message is carried in downlink control information DCI carried by the PDCCH for scheduling a system information block SIB.

[0129] In one embodiment, the notification sending module 401 is specifically configured to send a short message to the terminal, and the short message is used to indicate the DCI update.

[0130] In one embodiment, the first type of system message is carried on a logical channel by a broadcast control channel BCCH; the BCCH is mapped to DCI carried by the PDCCH for scheduling the DL-SCH.

[0131] In one embodiment, the format of the DCI is format 1_0 with cyclic redundancy check CRC scrambled by a system information radio network temporary identity SI-RNTI; the first type of system message is carried in reserved bit positions of the DCI.

[0132] In one embodiment, the format of the DCI is a specified format with cyclic redundancy check CRC scrambled by a system information radio network temporary identity SI-RNTI; the specified format is dedicated to carrying the first type of system message.
