Wherein, the access device 12 may be an evolved access device (eNB) adopted in a 4G system. Alternatively, the access device 12 may also be an access device (gNB) adopting a centralized and distributed architecture in the 5G system. When the access device 12 adopts a centralized distributed architecture, it usually includes a centralized unit (central unit, CU) and at least two distributed units (distributed unit, DU). The centralized unit is provided with a packet data convergence protocol (Packet Data Convergence Protocol, PDCP) layer, radio link layer control protocol (Radio Link Control, RLC) layer, media access control (Medium Access Control, MAC) layer protocol stack; A physical (Physical, PHY) layer protocol stack is set in the unit, and the embodiment of the present disclosure does not limit the specific implementation manner of the access device 12 .

As shown in FIG. 2 , an embodiment of the present disclosure provides a system message processing method, which is executed by a base station, and the method includes:

S210: Send first information, where the first information is used to indicate whether the MIB is updated.

The base station includes but not limited to eNB and/or gNB.

The first information may be sent by broadcast, multicast or unicast by the base station.

Exemplarily, the first information can be sent in various DCI, MAC CE or RRC signaling.

In the embodiment of the present disclosure, the paging (paging) downlink control information (Downlink Control Information, DCI) includes first information, and the first information will be used to indicate whether the MIB is updated. In this way, when the terminal receives the first information, it knows whether to monitor the MIB on the physical broadcast channel transmitting the MIB. In this way, unnecessary monitoring of the MIB by the terminal can be reduced, thereby reducing power consumption caused by unnecessary monitoring.

In one embodiment, the first information is included in paging DCI (paging DCI).

When the system message is updated, it will trigger the sending of paging message (paging). When sending a paging message, the base station will send paging DCI, which can be used for paging message scheduling and/or short message sending.

The system message may include various types of system message blocks. The system information block may include: a master information block MIB and a system information block SIBx, where x may be a positive integer, and the value of x may be various values such as 1, 2 or 3. For example, MIB and SIB1-SIB13 may be included.

In one embodiment, the first information may be one or more bits.

Exemplarily, the paging DCI may include: multiple indicators, and the remaining bit values of the multiple indicators may be used for whether the MIB is updated. For example, if the paging DCI has M bits, then there are 2 ^M bit values, some of which have been used to indicate other content, and the remaining unused bit values can be used to indicate whether the MIB has been updated.

Of course, the above is only an example of how the paging DCI specifically indicates whether the MIB is updated, and the specific implementation is not limited to the above examples.

In some embodiments, the method includes:

Send the second information, where the second information indicates whether the system information is updated.

The system information includes MIB and SIBx. If the MIB is updated, the system information must be updated. The second information and the first information can be sent in one message, or in different messages. Meanwhile, the base station may only send the first message, or only the second message, or may send the first message and the second message simultaneously or separately.

As shown in FIG. 3 , an embodiment of the present disclosure provides a system message processing method, which is executed by a base station, and the method includes:

S310: Send paging DCI, wherein the paging DCI includes: first information and/or second information; the first information is used to indicate whether the MIB has been updated; the second information is used to indicate whether the system information There are updates.

The second information is different from the first information. Exemplarily, the second information and the first information occupy different bits in the paging DCI.

The system information includes MIB and SIBx. In the embodiment of the present disclosure, the second information indicates whether the system message is updated, and the MIB belongs to one type of system message. Therefore, in an embodiment, the terminal can first determine the second information of the received paging DCI, and if the second information indicates that there is no system message update, the decoding of the first information can be skipped, thereby reducing unnecessary decoding . In another embodiment, when the second information indicates that the system message is not updated, the first information may not be sent or the first information may not indicate whether the MIB is updated. When the second information indicates that the system information has not been updated, the bit or bit value indicating whether there is an update in the MIB can be used to indicate other content, so as to achieve maximum effective use of each bit value in the paging DCI.

In some embodiments, the second information may be included in a short message indication field. The short message indication field may include one or more bits.

Table 1 is an example of a short message indication field:

Table 1

If the bit value of the second information is: 10 or 00, it may be considered that: the second information indicates that there is no update of the system message. If the bit value of the second information is: 01 or 11, it may be considered that: the second information indicates that there is an update of the system message. Any one element in Table 1 can be used alone, and any two or more elements in Table 1 can be used in combination.

In some embodiments, the paging DCI includes a short message indication field, and the first information may include: a short message indication field. The first information may be indicated by one or more bits. Exemplarily, the short message indication field may include a bitmap. One bit in the bitmap may indicate one kind of information, and the first information may be indicated by one or more bits in the bitmap.

In one embodiment, the paging DCI includes: a short message field. The first information may be included in a short message field.

Exemplarily, the short message domain may include at least one of the following indicators:

The first indicator indicates whether the system information other than SIB6, SIB7 and SIB8 has been updated;

The second indicator indicates whether there is at least one of the Earthquake and Tsunami Warning System (Earthquake and Tsunami Warning System, ETWS) primary notification, ETWS secondary notification, and Commercial Mobile Alert System (Commercial Mobile Alert System, CMDS) notification;

The third indicator indicates whether to stop monitoring the paging occasion PO of the current physical downlink control channel PDCCH;

The fourth indicator indicates whether the MIB has been updated.

The "indicator" described in all the embodiments of the present disclosure may be one bit or multiple bits, which is not limited here.

If the first indicator still has system information other than SIB6, SIB7 and SIB8 being updated, after receiving the paging DCI, the terminal will monitor the system information on the transmission channel of system information other than SIB6, SIB7 and SIB8. If the first indicator indicates that there is no update of system information other than SIB6, SIB7 and SIB8, the terminal does not need to monitor the transmission channel of system information other than IB6, SIB7 and SIB8.

The second indicator indicates whether the ETWS main notification, ETWS secondary notification and CMDS are updated, and when there is an update, the base station will send the updated ETWS main notification, ETWS secondary notification and CMDS through SIB10 and/or SIB11. That is, the ETWS main notification, the ETWS secondary notification and the CMDS notification can be carried in SIB10 and/or SIB11. Exemplarily, the ETWS main notification can be carried in SIB10, and the ETWS secondary notification can be carried in SIB11.

If the second indicator indicates that the ETWS main notification, ETWS secondary notification and CMDS are updated, the terminal will monitor the transmission channels of the ETWS main notification, ETWS secondary notification and CMDS after receiving the paging DCI to receive the updated ETWS main notification , ETWS Secondary Notification and CMDS, otherwise the transmission channel of ETWS Main Notification, ETWS Secondary Notification and CMDS will not be monitored.

In some embodiments, the third indicator can be used to indicate whether the terminal continues to monitor the PO corresponding to the current PDCCH. For example, if there is a paging message to be sent, usually the third indicator will indicate the PDCCH used by the terminal for the current paging DCI transmission. The corresponding PO monitors the paging message, otherwise, it is unnecessary to continue monitoring the PO corresponding to the current PDCCH, so as to reduce the power consumption generated by monitoring.

In the embodiment of the present disclosure, the first information is carried by a fourth indicator, and the fourth indicator may include one or more bits, and may be different from any one of the foregoing first to third indicators. The fourth indicator indicates whether the MIB has been updated. If the fourth indicator indicates that the MIB is updated, the terminal needs to monitor the Physical Broadcast Channel (PBCH) that transmits the MIB; otherwise, there is no need to monitor the PBCH that transmits the MIB, reducing the power consumption caused by monitoring the PBCH and extending the standby time of the terminal . Table 2 is an example of a short message domain:

Table 2

Any one element in Table 2 can be used alone, and any two or more elements in Table 2 can be used in combination. Meanwhile, the setting of 1 or true in Table 2 is just an example. Those skilled in the art can understand that setting 0 or false in the above Table 2 can also achieve the purpose of the invention. Therefore, these are just examples, and are just different expressions based on the same inventive concept.

Table 3 is an example of a short message domain:

table 3

Any one element in Table 3 can be used alone, and any two or more elements in Table 3 can be used in combination. Meanwhile, setting 1 or true in Table 3 is just an example for illustration. Those skilled in the art can understand that setting 0 or false in the above Table 2 can also achieve the purpose of the invention. Therefore, these are just examples, and are just different expressions based on the same inventive concept.

In an embodiment, the paging DCI further includes: a reserved bit field; the first information is included in the reserved bit field. The reserved bit field includes one or more reserved bits, which are reserved bits that have not been used for other information indications.

In some embodiments, the first information may be used to indicate to the first type of terminal whether the MIB is updated.

In some embodiments, the first type of terminal may be a terminal that supports a bandwidth less than a preset value, for example, a terminal that supports a bandwidth less than 20 MHz. In some other embodiments, terminals can be classified into first-type terminals and second-type terminals according to their terminal capabilities (for example, supported bandwidth). The bandwidth supported by the second type of terminal is greater than the bandwidth supported by the first type of terminal. Exemplarily, the second type of terminal may include: an enhanced mobile broadband (enhanced Mobile Broadband, eMBB) terminal. The first type of terminal may be a Redcap terminal. In some embodiments, the first type of terminal may be a capability reduction terminal (RedCap UE); and the second type of terminal may be an ordinary terminal (non-RedCap UE or Legacy UE); wherein the terminal capability of the first type of terminal is low on the second type of terminal.

The Redcap terminal can be divided into: a Redcap terminal that supports a maximum bandwidth of 20 MHz and an enhanced Redcap terminal that supports a maximum bandwidth of less than 20 MHz. The enhanced Redcap terminal can only support 5MHz.

MIB is transmitted using PBCH. If the subcarrier space (Sub Carrier Space, SCS) of PBCH is equal to or greater than 30KHz, the bandwidth of PBCH is relatively large, which will exceed the maximum bandwidth supported by the first type of terminal. Therefore, the first type of terminal needs more The complete MIB reception can be completed only once, and multiple receptions will lead to large energy consumption of the first type of terminal. Especially when the channel quality is not good, the first type of terminal needs to receive the MIB more times for one MIB update, and this phenomenon is even more serious.

Therefore, in some embodiments, the method also includes:

The first information is sent in response to the SCS of the PBCH being not less than a preset value.

That is, when the SCS is relatively large, the bandwidth of the PBCH that transmits the MIB is large, so the first type of terminal cannot completely receive the entire PBCH at one time, so it needs to receive it multiple times. In this way, the transmission of the first information can reduce the number of second messages. Unnecessary update of a class of terminals.

In an embodiment, the system message processing method performed by the base station may include:

When the SCS is greater than or equal to a preset value, sending the first information;

and / or,

When the SCS is smaller than the preset value, the first information is not sent.

For example, when the SCS is equal to 15 KHz, the short message field or the reserved bit field of the paging DCI does not need to specifically set the first information to indicate whether the MIB is updated. Of course, in some other embodiments, regardless of the value of the SCS, the base station can send the first information that can indicate whether the MIB has been updated. In still some embodiments, the first information is sent in response to the number of the first type of terminals in the cell reaching a specified value; and/or, in response to the number of the first type of terminals in the cell not exceeding When the specified value is reached, the first information is not sent.

Exemplarily, in response to a first type of terminal camping in the cell, sending the first information;

And/or, in response to no terminal of the first type residing in the cell, the first information is not sent.

In some embodiments, the specified value may be determined according to the area of the cell and/or the capacity of the cell. For example, the specified value may be positively correlated with cell area and/or cell capacity.

In some other embodiments, the specified value may be a set static value, for example, the specified value may be: a value stipulated in a communication protocol.

As shown in FIG. 4 , an embodiment of the present disclosure provides a system message processing method, which is executed by a terminal, and the method includes:

S410: Receive first information. Wherein, the first information is used to indicate whether the master system information block MIB has been updated.

The terminal may be of various types. Exemplarily, the terminal may be the foregoing first-type terminal and/or the second-type terminal.

In some embodiments, the first information may be information broadcast, multicast or unicast by the base station.

The terminal will receive first information indicating whether the MIB is updated. In this way, after the terminal receives the paging DCI, it can know whether to receive the MIB according to the analysis of the first information. If it does not need to receive the MIB, it does not need to monitor the PBCH transmitting the MIB, thereby reducing unnecessary MIB monitoring Power consumption generated by MIB monitoring.

Exemplarily, the first information may be included in paging DCI.

The terminal receives the paging DCI, where the paging DCI carries first information indicating whether the MIB is updated. In this way, after the terminal receives the paging DCI, it can know whether to receive the MIB according to the analysis of the first information. If it does not need to receive the MIB, it does not need to monitor the PBCH transmitting the MIB, thereby reducing unnecessary MIB monitoring Power consumption generated by MIB monitoring.

In some embodiments, the method also includes:

Receive second information, where the second information indicates whether the system information is updated.

The second information and the first message may be in the same message or in different messages.

In some embodiments, the paging DCI further includes: second information;

Wherein, the second information indicates whether the system information is updated.

The system message here may be any system message including the aforementioned MIB.

The second information indicates that the system information is updated, and the first information indicates that the MIB is updated, so the terminal needs to monitor the PBCH for transmitting the MIB, thereby reducing power consumption for monitoring.

In some other embodiments, when the second information indicates that there is no update of system information, the paging DCI may not carry the first information, so as to indicate whether the updated bit of the MIB is released and can be used for other information content instructions.

In an embodiment, the paging DCI may include: a short message indication field. The second information is included in the indication field of the short message.

In another embodiment, the paging DCI may include: a short message field and/or a reserved bit field.

The first information may be included in: the short message field or the reserved bit field.

As shown in FIG. 5 , an embodiment of the present disclosure provides a system message processing method, which is executed by a terminal, and the method includes:

S510: Receive paging DCI, where the paging DCI includes: first information and/or second information. Wherein, the second information indicates whether the system information is updated; the first information indicates whether the MIB is updated.

S520: Ignore the first information in response to the second information indicating that the system message is not updated.

If the terminal receives the second information of the paging DCI indicating that the system information is not updated, in order to reduce the power consumption generated by the decoding of the terminal, the terminal may directly ignore the first information, thereby reducing unnecessary decoding of the first information.

When the second information indicates that there is no system update session, the terminal does not need to receive the updated system message.

As shown in FIG. 6 , an embodiment of the present disclosure provides a method for processing a system message, which is executed by a terminal, and the method further includes:

S610: Receive paging DCI, where the paging DCI includes: first information and/or second information; where the second information indicates whether the system information is updated; the first information indicates whether the MIB There are updates.

S620: In response to the second information indicating that the system information is updated, determine whether the MIB is updated according to the first information.

When the second information indicates that there is an update of the system information, the MIB may be updated. Therefore, it is necessary to check the first information to further determine whether the MIB is updated.

When the second information indicates that no system information is updated, the MIB must not be updated, and it is not necessary to further determine whether there is an MIB update according to the first information. That is, when the second information indicates that there is an update of the system information, the determining operation of determining whether there is an update to the MIB according to the first information needs to be performed.

If it is determined according to the first information that the MIB is not updated, there is no need to receive the MIB.

If it is determined according to the first information that the MIB is updated, the MIB needs to be received.

In some embodiments, the method also includes:

S630: Receive the MIB in response to the second information indicating that the system information is updated and the first information indicating that the MIB is updated.

If the second information indicates that the system information is updated and the first information indicates that the MIB is updated, the UE monitors the PBCH for transmitting the MIB so as to receive the MIB.

If the second information indicates that the system information is updated and the first information indicates that the MIB is not updated, monitor the SIBs on the broadcast channel with updated SIBs according to whether other SIBs indicated by the first information are updated.

Exemplarily, for example, when the first indicator indicates that system information other than SIB6 to SIB8 is updated, monitor a transmission channel on which system information other than SIB6 to SIB8 has an update, so as to receive the updated system information.

The second information is included in the indication field of the short message.

The first information is included in the short message field.

In some embodiments, the short message domain includes:

The second indicator indicates whether there is at least one of the earthquake and tsunami warning system ETWS main notification, ETWS secondary notification and commercial mobile warning service CMDS notification;

The fourth indicator indicates whether the MIB has been updated.

If the first indicator still has system information other than SIB6, SIB7 and SIB8 being updated, after receiving the paging DCI, the terminal will monitor the system information on the transmission channel of system information other than SIB6, SIB7 and SIB8.

If the first indicator indicates that there is no update of system information other than SIB6, SIB7 and SIB8, the terminal does not need to monitor the transmission channel of system information other than IB6, SIB7 and SIB8.

In some embodiments, the third indicator will indicate whether the terminal continues to monitor the PO corresponding to the current PDCCH. For example, if there is a paging message to be sent, usually the third indicator will indicate that the terminal is in the PO corresponding to the PDCCH used for the current paging DCI transmission. The PO monitors the paging message, otherwise, it does not need to continue to monitor the PO corresponding to the current PDCCH, so as to reduce the power consumption generated by monitoring.

In the embodiment of the present disclosure, the short message field further includes a fourth indicator, which may include one or more bits, and may be different from any one of the foregoing first to third indicators. The fourth indicator indicates whether the MIB has been updated. If the fourth indicator indicates that the MIB is updated, the terminal needs to monitor the Physical Broadcast Channel (PBCH) that transmits the MIB; otherwise, there is no need to monitor the PBCH that transmits the MIB, reducing the power consumption caused by monitoring the PBCH and extending the standby time of the terminal .

In an embodiment, the first information is also included in a reserved bit field of the paging DCI. In some embodiments, the first information indicates whether the MIB for the first type of terminal is updated.

In some embodiments, the first type of terminal is a Redcap terminal.

The bandwidth supported by the Redcap terminal is relatively small, for example, a terminal less than 20MHz. Because the supported bandwidth of the Redcap terminal is relatively small, if the SCS used by PBCH is greater than or equal to 30KHz, it needs multiple receptions to receive a complete PBCH, and only through combined decoding can it be correctly received and decoded to MIB. However, in the embodiment of the present disclosure, it is very necessary for the first information to indicate whether the MIB is updated; otherwise, the Redcap terminal still monitors the MIB when there is no MIB update, which will cause a lot of unnecessary power consumption.

The embodiment of the present disclosure provides a method for processing system messages, which will notify whether the MIB is updated, thereby avoiding unnecessary reading of the MIB. Reduce power overhead.

The paging DCI includes first information, and the first information is used to indicate whether the first type terminal needs to update the MIB message. In response to the first information indicating that the MIB message is updated, the terminal reads the MIB; otherwise, the terminal skips updating the MIB.

Further, the terminal of the first type determines whether to read the first information according to the second information. For example, the paging DCI includes the second information, and the second information is used to indicate whether the system information is updated. In response to the second information indicating that the system information is updated, the terminal of the first type further reads the first information to further determine whether the MIB is updated. Or in response to the second information indicating that the system information has been updated, the first information is not read.

As shown in FIG. 7 , an embodiment of the present disclosure provides a system message processing device, the device includes:

The sending module 710 is configured to send first information, where the first information is used to indicate whether the MIB is updated.

The system message processing device may be included in a base station.

In some embodiments, the sending module 710 may be a program module; after the program module is executed by the processor, it can realize the sending of the above-mentioned first information, and indicate whether the MIB is updated through the first information.
