Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of wireless communication, and more particularly to a system message processing method and apparatus, a communication device, and a storage medium. BACKGROUND

[0002] In a long term evolution (LTE) mobile communication system, machine type communication (MTC) and narrow band Internet of thing (NB-IoT) are proposed to support Internet of thing services. These two technologies are mainly aimed at low rate and / or high latency communication scenarios. For example, MTC devices only support a transmission rate of several M, which obviously cannot meet the communication scenarios with transmission rates of tens or even hundreds. Therefore, a reduced capability (Redcap) user equipment (UE) or terminal is proposed to meet the above communication demand of high transmission rate. SUMMARY

[0030] Reference is made to Figure 1 which shows a structural schematic diagram of a wireless communication system provided by the example embodiments. As shown in Figure 1 , the wireless communication system is a communication system based on cellular mobile communication technology, and the wireless communication system can include a plurality of UEs 11 and a plurality of access devices 12.

Alternatively, the access device 12 can also be an access device (gNB) using a centralized and distributed architecture in a 5G system. When the access device 12 uses a centralized and distributed architecture, it usually includes a central unit (CU) and at least two distributed units (DUs). The central unit is provided with a protocol stack of a packet data convergence protocol (PDCP) layer, a radio link control (RLC) layer, and a medium access control (MAC) layer; the distributed unit is provided with a physical (PHY) layer protocol stack, and the specific implementation of the access device 12 is not limited in the embodiments of the present disclosure.

[0034] The access device 12 and the UE 11 can establish a wireless connection through a wireless air interface. In different embodiments, the wireless air interface is a wireless air interface based on a fourth generation mobile communication network technology (4G) standard; or the wireless air interface is a wireless air interface based on a fifth generation mobile communication network technology (5G) standard, such as a new air interface; or the wireless air interface can also be a wireless air interface based on a more next generation mobile communication network technology standard of 5G.

Alternatively, the network management device can also be other core network devices, such as a Serving GateWay (SGW), a Public Data Network GateWay (PGW), a Policy and Charging Rules Function (PCRF), or a Home Subscriber Server (HSS), etc. The implementation form of the network management device 13 is not limited in the embodiments of the present disclosure.

[0038] As shown in FIG. 1, the embodiments of the present disclosure provide a system message processing method, wherein the method is performed by a base station, and the method comprises: Figure 2

[0039] S210: transmitting first information, wherein the first information is used to indicate whether the MIB is updated.

[0040] The base station includes but is not limited to eNB and / or gNB.

[0041] The first information can be broadcasted, multicast or unicast by the base station.

[0042] Exemplarily, the first information can be transmitted in various DCI, MAC CE or RRC signaling.

[0043] In the embodiments of the present disclosure, the paging Downlink Control Information (DCI) includes the first information, which is used to indicate whether the MIB is updated. In this way, when the terminal receives the first information, it knows whether to listen to the MIB on the physical broadcast channel where the MIB is transmitted. In this way, unnecessary listening of the terminal to the MIB can be reduced, and the power consumption caused by unnecessary listening can be reduced.

[0044] In one embodiment, the first information is contained in the paging DCI.

[0045] ​When the system information is updated, a paging message is triggered to be sent. The base station sends a paging DCI, which can be used for scheduling of the paging message and / or sending of a short message.

[0046] The system information can include various types of system information blocks. The system information blocks can include a master information block (MIB) and a system information block (SIBx), where x can be a positive integer, and x can be 1, 2, 3, etc. For example, the MIB and SIB1-SIB13 can be included.

[0047] In one embodiment, the first information can be one or more bits.

[0048] For example, the paging DCI can include a plurality of indicators, and the remaining bit values of the plurality of indicators can be used to indicate whether the MIB is updated. For example, the paging DCI has M bits, and 2 M bit values, some bit values have been used to indicate other content, and the remaining unused bit values can be used to indicate whether the MIB is updated.

[0049] 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 example.

[0050] In some embodiments, the method comprises:

[0051] The second information indicates whether the system information is updated.

[0052] The system information includes the MIB and the 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. At the same time, the base station can send only the first message, or only the second message, or send the first message and the second message at the same time or separately.

[0053] As Figure 3 shown in FIG. 10, the embodiment of the present disclosure provides a system information processing method, wherein the method is performed by a base station, and the method comprises:

[0054] S310: sending a paging DCI, wherein the paging DCI includes first information and / or second information; the first information is used to indicate whether the MIB is updated; and the second information is used to indicate whether the system information is updated.

[0055] The second information is different from the first information. For example, the second information and the first information occupy different bits in the paging DCI.

[0056] The system message includes the MIB and the SIBx. In the embodiments of the present disclosure, the second information indicates whether the system message is updated, and the MIB belongs to the system message. Therefore, in one embodiment, the terminal can first determine the second information of the received paging DCI, and if the second information indicates that the system message is not updated, the terminal can skip the decoding of the first information, thereby reducing unnecessary decoding. In another embodiment, if the second information indicates that the system message is not updated, the first information can not be sent or the first information can not indicate whether the MIB is updated. When the second information indicates that the system message is not updated, the bit or bit value indicating whether the MIB is updated can be used to indicate other contents, thereby achieving the maximum effective use of each bit value in the paging DCI.

[0057] In some embodiments, the second information can be included in a short message indication field. The short message indication field can include one or more bits.

[0058] Table 1 is an example of a short message indication field:

[0059]

[0060] Table 1

[0061] If the bit value of the second information is 10 or 00, it can be considered that the second information indicates that the system message is not updated. If the bit value of the second information is 01 or 11, it can be considered that the second information indicates that the system message is updated. Any element in Table 1 can be used alone, and any two or more elements in Table 1 can be used in combination.

[0062] In some embodiments, the paging DCI includes a short message indication field, and the first information can include the short message indication field. The first information can be indicated by one or more bits. For example, the short message indication field can include a bit bitmap. One bit in the bit bitmap can indicate one information, and the first information can be indicated by one or more bits in the bit bitmap.

[0063] In one embodiment, the paging DCI includes a short message field. The first information can be included in the short message field.

[0064] For example, the short message field can include at least one indicator of the following:

[0065] The first indicator indicates whether the system message other than the SIB6, the SIB7 and the SIB8 is updated;

[0066] a second indicator indicating whether at least one of a primary Earthquake and Tsunami Warning System (ETWS) notification, a secondary ETWS notification, and a Commercial Mobile Alert System (CMAS) notification is present;

[0067] a third indicator indicating whether to stop monitoring a paging occasion (PO) of a current physical downlink control channel (PDCCH);

[0068] a fourth indicator indicating whether the MIB is updated.

[0069] In all embodiments of the present disclosure, the "indicator" can be one bit or multiple bits, which is not limited herein.

[0070] If the first indicator indicates that there is an update of the system information other than SIB6, SIB7 and SIB8, after the terminal receives the paging DCI, the terminal will monitor the transmission channel of the system information other than SIB6, SIB7 and SIB8. If the first indicator indicates that there is no update of the system information other than SIB6, SIB7 and SIB8, the terminal does not need to monitor the transmission channel of the system information other than SIB6, SIB7 and SIB8.

[0071] The second indicator indicates whether the ETWS primary notification, the ETWS secondary notification and the CMDS are updated, and when updated, the base station transmits the updated ETWS primary notification, ETWS secondary notification and CMDS through SIB10 and / or SIB11. That is, the ETWS primary notification, the ETWS secondary notification and the CMDS notification can be carried in SIB10 and / or SIB11. Exemplarily, the ETWS primary notification can be carried in SIB10, and the ETWS secondary notification can be carried in SIB11.

[0072] If the second indicator indicates that the ETWS primary notification, the ETWS secondary notification and the CMDS are updated, after the terminal receives the paging DCI, the terminal will monitor the transmission channel of the ETWS primary notification, the ETWS secondary notification and the CMDS to receive the updated ETWS primary notification, ETWS secondary notification and CMDS, otherwise the terminal will not monitor the transmission channel of the ETWS primary notification, the ETWS secondary notification and the CMDS.

[0073] 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, whether there is a paging message to be transmitted. Generally, the third indicator will indicate the terminal to monitor the paging message on the PO corresponding to the PDCCH used in the current paging DCI transmission, otherwise the terminal can not continue to monitor the PO corresponding to the current PDCCH, reducing the power consumption caused by monitoring.

[0074] In the embodiments of the present disclosure, the first information is carried by a fourth indicator, which can include one or more bits and can be different from any one of the first to third indicators. The fourth indicator indicates whether the MIB is updated. If the fourth indicator indicates that the MIB is updated, the terminal needs to monitor the physical broadcast channel (PBCH) transmitting the MIB; otherwise, it is not necessary to monitor the PBCH transmitting the MIB, reducing the power consumption caused by monitoring the PBCH and prolonging the standby time of the terminal. Table 2 is an example of a short message field:

[0075]

[0076]

[0077] Table 2

[0078] 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 only an example. Those skilled in the art can understand that the setting of 0 or false in the above Table 2 can also achieve the purpose of the application. Therefore, these are only examples, and are only different expressions based on the same inventive concept.

[0079] Table 3 is an example of a short message field:

[0080]

[0081] Table 3

[0082] 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, the setting of 1 or true in Table 3 is only an example. Those skilled in the art can understand that the setting of 0 or false in the above Table 2 can also achieve the purpose of the application. Therefore, these are only examples, and are only different expressions based on the same inventive concept.

[0083] In an embodiment, the paging DCI further comprises: a reserved bit field; and the first information is contained in the reserved bit field. The reserved bit field comprises one or more reserved bits, which are bits reserved and not used for other information indication.

[0084] In some embodiments, the first information can be used to indicate to the first type of terminal whether there is an update to the MIB.

[0085] In some embodiments, the first type of terminal can be a terminal supporting a bandwidth less than a preset value, for example, a terminal supporting a bandwidth less than 20 MHz. In other embodiments, terminals can be divided into first type of terminals and second type of terminals according to their terminal capabilities (e.g., supported bandwidth). The second type of terminal supports a bandwidth greater than the bandwidth supported by the first type of terminal. Illustratively, the second type of terminal can include an enhanced mobile broadband (eMBB) terminal. The first type of terminal can be a Redcap terminal. In some embodiments, the first type of terminal can be a reduced capability terminal (RedCap UE); and the second type of terminal can be a normal terminal (non-RedCap UE or Legacy UE); wherein the terminal capability of the first type of terminal is lower than that of the second type of terminal.

[0086] The Redcap terminal can be further divided into a Redcap terminal supporting a maximum of 20 MHz and an enhanced Redcap terminal supporting a maximum bandwidth less than 20 MHz. The enhanced Redcap terminal can only support 5 MHz.

[0087] The MIB is transmitted using PBCH. If the subcarrier spacing (SCS) of the PBCH is equal to or greater than 30 KHz, the bandwidth of the PBCH is large and can exceed the maximum bandwidth supported by the first type of terminal. Therefore, the first type of terminal needs to receive multiple times to complete the complete MIB reception, which can cause the first type of terminal to consume a large amount of energy. Especially when the channel quality is not good, one MIB update requires the first type of terminal to receive the MIB more times, which makes the phenomenon more serious.

[0088] Therefore, in some embodiments, the method further comprises:

[0089] In response to the SCS of the PBCH being not less than a preset value, transmitting the first information.

[0090] That is, when the SCS is large, the bandwidth of the PBCH transmitting the MIB is large, so the first type of terminal cannot receive the entire PBCH at one time and needs to receive multiple times. Therefore, by transmitting the first information, unnecessary updates of the first type of terminal can be reduced.

[0091] In an embodiment, a system message processing method performed by a base station can include:

[0092] transmitting the first information when the SCS is greater than or equal to a preset value;

[0093] and / or,

[0094] not transmitting the first information when the SCS is less than the preset value.

[0095] For example, when the SCS is equal to 15 KHz, the short message field or the reserved bit field of the paging DCI can not be specially configured to indicate whether the MIB is updated. Of course, in other embodiments, the base station can transmit the first information to indicate whether the MIB is updated regardless of the value of the SCS. In still other embodiments, the first information is transmitted in response to the number of the first type of terminals in the cell reaching a specified value; and / or, the first information is not transmitted in response to the number of the first type of terminals in the cell not reaching the specified value.

[0096] For example, the first information is transmitted in response to the first type of terminal residing in the cell;

[0097] and / or, the first information is not transmitted in response to the first type of terminal not residing in the cell.

[0098] In some embodiments, the specified value can be determined according to the cell area and / or the cell capacity. For example, the specified value can be positively correlated with the cell area and / or the cell capacity.

[0099] In other embodiments, the specified value can be a set static value. For example, the specified value can be a value agreed by a communication protocol.

[0100] As shown in FIG. 4, an embodiment of the present disclosure provides a system message processing method, wherein the method is performed by a terminal and includes: Figure 4 S410: receiving first information. The first information is used to indicate whether a master system information block (MIB) is updated.

[0101] The terminal can be various types of terminals. For example, the terminal can be the first type of terminal and / or the second type of terminal.

[0102] In some embodiments, the first information can be information broadcasted, groupcasted or unicasted by a base station.

[0103]

[0104] ​The terminal receives first information indicating whether the MIB is updated. Thus, after receiving the paging DCI, the terminal can know whether the MIB needs to be received according to the analysis of the first information, and thus does not need to listen to the PBCH transmitting the MIB when the MIB does not need to be received, thereby reducing unnecessary MIB listening and power consumption caused by unnecessary MIB listening.

[0105] Exemplarily, the first information can be included in the paging DCI.

[0106] The terminal receives the paging DCI carrying the first information indicating whether the MIB is updated. Thus, after receiving the paging DCI, the terminal can know whether the MIB needs to be received according to the analysis of the first information, and thus does not need to listen to the PBCH transmitting the MIB when the MIB does not need to be received, thereby reducing unnecessary MIB listening and power consumption caused by unnecessary MIB listening.

[0107] In some embodiments, the method further includes:

[0108] Receiving second information indicating whether the system message is updated.

[0109] The second information and the first information can be in the same message or in different messages.

[0110] In some embodiments, the paging DCI further includes second information.

[0111] The second information indicates whether the system message is updated.

[0112] The system message herein can be any system message including the aforementioned MIB.

[0113] When the second information indicates that the system message is updated and the first information indicates that the MIB is updated, the terminal needs to listen to the PBCH transmitting the MIB, thereby reducing listening power consumption.

[0114] In some embodiments, when the second information indicates that there is no system message update, the paging DCI can not carry the first information, and thus the bit indicating whether the MIB is updated is released and can be used for indicating other information content.

[0115] In one embodiment, the paging DCI can include a short message indication field. The second information is included in the short message indication field.

[0116] In another embodiment, the paging DCI can include a short message field and / or a reserved bit field.

[0117] The first information can be included in the short message field or the reserved bit field.

[0118] As shown in Figure 5 , the embodiment of the present disclosure provides a system message processing method, wherein the method is executed by a terminal, and the method comprises the following steps:

[0119] S510: receiving a paging DCI, wherein the paging DCI comprises first information and / or second information; wherein the second information indicates whether there is an update of a system message; and the first information indicates whether there is an update of the MIB.

[0120] S520: in response to the second information indicating that there is no update of the system message, ignoring the first information.

[0121] If the second information of the paging DCI received by the terminal indicates that there is no update of the system message, in order to reduce the power consumption caused by the decoding of the terminal, the terminal can directly ignore the first information, thereby reducing unnecessary decoding of the first information.

[0122] When the second information indicates that there is no system update, the terminal does not need to receive the updated system message.

[0123] As shown in Figure 6 , the embodiment of the present disclosure provides a system message processing method, wherein the method is executed by a terminal, and the method further comprises the following steps:

[0124] S610: receiving a paging DCI, wherein the paging DCI comprises first information and / or second information; wherein the second information indicates whether there is an update of a system message; and the first information indicates whether there is an update of the MIB.

[0125] S620: in response to the second information indicating that there is an update of the system message, determining whether there is an update of the MIB according to the first information.

[0126] When the second information indicates that there is an update of the system message, the MIB is likely to be updated, so it is necessary to check the first information to further determine whether the MIB is updated.

[0127] When the second information indicates that there is no update of the system message, the MIB is definitely not updated, so it is not necessary to further determine whether there is an update of the MIB according to the first information. That is, only when the second information indicates that there is an update of the system message, it is necessary to perform the determining operation of determining whether the MIB is updated according to the first information.

[0128] If it is determined that there is no update of the MIB according to the first information, the MIB does not need to be received.

[0129] If it is determined that there is an update of the MIB according to the first information, the MIB needs to be received.

[0130] In some embodiments, the method further comprises:

[0131] S630: receiving the MIB in response to the second information indicating that the system message is updated and the first information indicating that the MIB is updated.

[0132] If the second information indicates that the system message is updated and the first information indicates that the MIB is updated, the UE monitors a PBCH transmitting the MIB, so that the MIB can be received.

[0133] If the second information indicates that the system message is updated and the first information indicates that the MIB is not updated, the UE monitors a SIB on a broadcast channel of a SIB indicated by the first information according to whether the SIB is updated.

[0134] For example, the first indicator indicates that the system message other than SIB6-SIB8 is updated, the UE monitors a transmission channel of the system message other than SIB6-SIB8, so that the updated system message can be received.

[0135] The second information is included in a short message indication field.

[0136] The first information is included in a short message field.

[0137] In some embodiments, the short message field includes:

[0138] A first indicator indicating whether the system message other than SIB6-SIB8 is updated;

[0139] A second indicator indicating whether at least one of an earthquake and tsunami warning system (ETWS) primary notification, an ETWS secondary notification, and a commercial mobile alert service (CMDS) notification is updated;

[0140] A third indicator indicating whether to stop monitoring a paging occasion (PO) of a current physical downlink control channel (PDCCH);

[0141] A fourth indicator indicating whether the MIB is updated.

[0142] If the first indicator indicates that the system message other than SIB6-SIB8 is updated, after the terminal receives the paging DCI, the terminal monitors the transmission channel of the system message other than SIB6-SIB8.

[0143] If the first indicator indicates that the system message other than SIB6-SIB8 is not updated, the terminal does not need to monitor the transmission channel of the system message other than SIB6-SIB8.

[0144] The second indicator indicates whether the ETWS primary notification, the ETWS secondary notification, and the CMDS are updated, and when the ETWS primary notification, the ETWS secondary notification, and the CMDS are updated, the base station transmits the updated ETWS primary notification, the ETWS secondary notification, and the CMDS through the SIB10 and / or the SIB11. That is, the ETWS primary notification, the ETWS secondary notification, and the CMDS notification can be carried in the SIB10 and / or the SIB11. Exemplarily, the ETWS primary notification can be carried in the SIB10, and the ETWS secondary notification can be carried in the SIB11.

[0145] If the second indicator indicates that the ETWS primary notification, the ETWS secondary notification, and the CMDS are updated, after receiving the paging DCI, the terminal listens to a transmission channel of the ETWS primary notification, the ETWS secondary notification, and the CMDS to receive the updated ETWS primary notification, the ETWS secondary notification, and the CMDS, and otherwise will not listen to the transmission channel of the ETWS primary notification, the ETWS secondary notification, and the CMDS.

[0146] In some embodiments, the third indicator indicates whether the terminal continues to listen to the PO corresponding to the current PDCCH. For example, when there is a paging message to be transmitted, the third indicator generally indicates that the terminal listens to the paging message in the PO corresponding to the PDCCH used for the current paging DCI transmission, and otherwise, the terminal can not continue to listen to the PO corresponding to the current PDCCH, thereby reducing the power consumption caused by listening.

[0147] In the embodiments of the present disclosure, the short message field further includes a fourth indicator, which can include one or more bits and can be different from any one of the first indicator to the third indicator. The fourth indicator indicates whether the MIB is updated. If the fourth indicator indicates that the MIB is updated, the terminal needs to listen to a physical broadcast channel (PBCH) that transmits the MIB; otherwise, the terminal does not need to listen to the PBCH that transmits the MIB, thereby reducing the power consumption caused by listening to the PBCH and prolonging the standby time of the terminal.

[0148] In an embodiment, the first information is further 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.

[0149] In some embodiments, the first type of terminal is a Redcap terminal.

[0150] Redcap terminals support relatively small bandwidths, for example, less than 20MHz. Because of this limited bandwidth, if the PBCH uses an SCS greater than or equal to 30kHz, multiple receptions are required to receive a complete PBCH. Only through merging and decoding can it be correctly received and decoded into the MIB. Therefore, in this embodiment, the first information indicating whether the MIB has been updated is essential; otherwise, the Redcap terminal continuing to monitor the MIB when there is no MIB update would lead to unnecessary power consumption.

[0151] This disclosure provides a method for processing system messages, which notifies the MIB whether there are updates, thereby avoiding unnecessary MIB reads and reducing power consumption.

[0152] The paging DCI includes first information indicating whether a first-type terminal needs to update its MIB message. In response to the first information indicating an MIB message update, the terminal reads the MIB; otherwise, the terminal skips the MIB update.

[0153] Furthermore, the first type of terminal determines whether it needs to read the first information based on the second information. For example, the second information may be included in the paging DCI, indicating whether the system message has been updated. In response to the second information indicating that the system message has been updated, the first type of terminal further reads the first information to further determine whether the MIB has been updated. Alternatively, in response to the second information indicating that the system message has been updated, the first information may not be read.
