Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of wireless communication, and particularly relates to a paging indication method and device, a network side equipment and a terminal. BACKGROUND

[0002] In the related art, a network side can send a paging to a user equipment (UE) in an idle state, an inactive state and a connected state, and the paging process can be used to notify a certain UE to receive a paging request and / or to notify a system information update, and to notify the UE to receive information such as an Earthquake and Tsunami Warning System (ETWS) and a Commercial Mobile Alert Service (CMAS).

[0003] For each UE, one paging occasion (PO) needs to be detected in one discontinuous reception (DRX) cycle. The UE calculates its corresponding paging frame and paging occasion according to the UE_ID and the DRX cycle and the configuration information of the network about the paging. When the paging is for transmitting a paging request to a certain UE, the PO contains a paging physical downlink control channel (PDCCH), wherein the paging PDCCH contains a short message indicator, and a time-frequency resource position of a physical downlink shared channel (PDSCH) of a paging message. When the paging is for notifying a system information update or a public emergency notification, the paging PDCCH contains a short message indicator and a short message.

[0004] The UE in the idle state or the inactive state performs PDCCH detection on its corresponding PO in each DRX cycle, and if a PDCCH scrambled by a paging radio network temporary identifier (P-RNTI) is detected, it is judged that the paging is for transmitting a paging message and / or a system information update notification and / or an ETWS / CMAS notification; if it is for transmitting a paging message, the UE continues to receive a PDSCH, and judges from the received PDSCH whether its paging message is carried therein.

[0005] In the related art, when only some UEs of a high version (for example, R17 and / or a beyond version) and having a corresponding capability are paged at the network side, UEs of a low version (for example, R15 and / or R16 version) or not having the corresponding capability will also receive the paging PDCCH. If the paging is for finding the UE through a paging message, the UE of the low version will also continue to receive the PDSCH according to the scheduling information indicated by the paging PDCCH; if the paging is for indicating a system information change notification of the UE of the high version, the UE of the low version will also wake up at the next modification period to receive the updated system information. Thus, unnecessary power consumption of the UE of the low version is caused. SUMMARY

[0036] Figure 2 A flowchart of a paging indication method in the embodiments of the present application is shown. The method 200 can be performed by a network-side device. In other words, the method can be performed by software or hardware installed on the network-side device. As shown in the method can include the following steps. Figure 2

[0037] S210, sending paging indication information, wherein the paging indication information indicates paging information of a target terminal, and the target terminal includes a terminal with a specific capability.​

[0038] In the embodiments of the present application, the terminal with the specific capability can be a terminal of a specified version, for example, a terminal of R17 and / or a terminal of a higher version.

[0039] In a possible implementation manner of the embodiments of the present application, the paging indication information can include at least one of the following:

[0040] (1) Short message indication in the paging PDCCH, wherein a value of the short message indication is a first preset value.

[0041] In the embodiments of the present application, the short message indication in the paging PDCCH is a short message indicator in the downlink control information (DCI) carried on the paging PDCCH.

[0042] For example, in the related art, 2 bits are used to represent the short message indication in the downlink control information (DCI) format 1_0, wherein “00” is a reserved value, “01” indicates that only scheduling information of a paging message is in the DCI, “10” indicates that only a short message is in the DCI, and “11” indicates that both the scheduling information of the paging message and the short message are in the DCI. Therefore, “00” can be used to indicate the paging information of the target terminal. That is, the first preset value is “00”. That is, if the value of the short message indication is the first preset value, it indicates that only the paging information of the target terminal exists in the paging PDCCH.

[0043] (2) A preset bit of a short message in the paging PDCCH, wherein a value of the preset bit is a second preset value.

[0044] The preset bit can be a bit that cannot be recognized by a UE without the specific capability.

[0045] In the embodiments of the present application, the short message in the paging PDCCH is a short message in the downlink control information (DCI) carried on the paging PDCCH.

[0046] For example, in the related art, 8 bits are used to represent the short message (Short Message) in the DCI format 1_0, and the meaning of each bit is shown in Table 1.

[0047] Table 1.

[0048]

[0049] The preset bit can be any one of the reserved bits, i.e., the 4th to 8th bits, in 8 bits representing a short message in the DCI format 1_0, and the value of the preset bit is 1, indicating the paging information of the target terminal.

[0050] (3) Paging Early Indicator (PEI).

[0051] For the UE in the idle state, radio resource management (RRM) measurement and paging PDCCH reception are needed, and the paging PDCCH is a PDCCH scrambled with a P-RNTI (Paging-Radio Network Temporary Identifier). If the paging PDCCH is received, the paging PDCCH can be used to transmit CMAS and ETWS, and / or to page the UE. When the paging PDCCH indicates scheduling of a PDSCH, the PDSCH is used to page the UE. Since the probability of the existence of a paged UE in one PO is usually not high, if the UE periodically detects the paging PDCCH, the paging PDCCH cannot be detected in most cases, resulting in unnecessary power consumption. In order to reduce the power consumption of the terminal, in each DRX cycle (i.e., paging cycle) of the UE in the idle state, before the UE performs blind detection of the paging PDCCH in the PO, the base station sends a paging early indication signal to the UE. The UE determines whether to listen to the paging PDCCH in the subsequent PO according to the paging early indication. The paging early indication signal can indicate whether the UE needs to wake up to listen to the subsequent PO, thereby saving the power consumption required for synchronization channel measurement, etc. due to the need to receive one or more synchronization signals / physical broadcast channel signal blocks (or synchronization signal blocks) (Synchronization Signal and PBCH block, SSB) according to the channel quality before listening to the PO, thereby achieving terminal energy saving.

[0052] In the embodiments of the present application, the paging information of the target terminal can be indicated by the PEI.

[0053] In the embodiments of the present application, the paging information of the target terminal can also be indicated by two or three of the above three in combination.

[0054] In the embodiments of the present application, correspondingly, the specific capability includes but is not limited to at least one of the following:

[0055] (1) identifying the indication information of the short message indication in the paging PDCCH as the first preset value.

[0056] For example, if the paging indication information includes the short message indication in the paging PDCCH as the first preset value, the specific capability includes identifying the indication information of the short message indication in the paging PDCCH as the first preset value. That is, the target terminal should have the capability of identifying the short message indication as the first preset value.

[0057] (2) identifying the indication information of the value of the preset bit of the short message in the paging PDCCH as the second preset value.

[0058] For example, if the paging indication information includes the short message with the value of the preset bit as the second preset value in the paging PDCCH, the specific capability includes identifying the indication information of the value of the preset bit of the short message in the paging PDCCH as the second preset value. That is, the target terminal should have the capability of identifying the short message with the value of the preset bit as the second preset value.

[0059] (3) supporting PEI.

[0060] For example, if the paging indication information includes PEI, the specific capability includes supporting PEI. That is, the target terminal supports PEI and can detect and identify PEI.

[0061] In the embodiments of the present application, the paging indication information indicates the paging information of the target terminal to include at least one of the following (that is, the paging indication information can indicate the paging information of the target terminal through at least one of the following):

[0062] (1) indicating first specific information, wherein the first specific information is scheduling information of only the paging message of the target terminal in the paging PDCCH.

[0063] That is, the paging indication information indicates the scheduling information of only the paging message of the target terminal in the paging PDCCH, and therefore, the non-target terminal does not need to detect the PDSCH according to the scheduling information in the paging PDCCH.

[0064] (2) indicating second specific information, wherein the second specific information is a notification of only the system information change of the target terminal.

[0065] That is, the paging indication information is a system information change notification, and the system information change indicated by the notification is the system information change of the target terminal, and the non-target terminal does not need to wake up to receive the changed system information in the next change period.

[0066] In a specific application, the short message indication in the paging PDCCH can be set to a first preset value to indicate the first specific information and / or the second specific information.

[0067] For example, the bit field of the short message indication can be set to "00" to indicate the following information:

[0068] (1) only the scheduling information of the paging message of the UE with corresponding capability of R17 and / or beyond version exists in the paging PDCCH;

[0069] (2) only the system information change notification of the UE with corresponding capability of R17 and / or beyond version exists;

[0070] (3) the system information change (e.g., system information change other than SIB6, SIB7 and SIB8) notification of the UE with corresponding capability of R17 and / or beyond version and the scheduling information of the paging message exist in the paging PDCCH.

[0071] In one possible implementation, the paging information of the target terminal can also be indicated by setting the short message indication in the paging PDCCH in combination with the short message. In this possible implementation, the sending of the paging indication information can include: sending the paging PDCCH, wherein the short message indication in the paging PDCCH is set to indicate that there is no scheduling information of the paging message in the target DCI, and the preset bit of the short message in the paging PDCCH indicates the second specific information, wherein the target DCI is the DCI on the paging PDCCH. That is, in this possible implementation, the short message indication in the paging PDCCH indicates that there is no scheduling information of the paging message in the target DCI, for example, the bit field of the short message indication is set to "10" to indicate that only the short message exists in the DCI. While the preset bit of the short message is set to a second preset value to indicate the system information change of the target terminal, the target terminal can determine that the system information needs to be updated according to the indication, and therefore wakes up to receive the updated system information in the next modification period; and the non-target terminal ignores the indication of the short message and will not wake up to receive the updated system information in the next modification period.

[0072] In a specific application, the PEI can also be used in combination with the short message indication and / or the short message for indication. For example, in one possible implementation, the sending of the paging indication information can include:

[0073] Step 1, sending the PEI, wherein the PEI indicates whether the scheduling information of the paging message and / or the short message exists in the paging PDCCH at the target paging occasion corresponding to the PEI;

[0074] Step 2, sending the paging PDCCH, wherein a value of a short message in the paging PDCCH is a third preset value, the third preset value indicating that there is no scheduling information of a paging message in the paging PDCCH; the short message in the paging PDCCH is set as one of the following: preset bit positions of the short message indicating the second specific information, all bit positions of the short message being invalid to indicate the first specific information, and no short message being sent on the paging PDCCH to indicate the first specific information;

[0075] The target DCI is a DCI on the paging PDCCH.

[0076] In the above possible implementation, the target terminal can detect the PEI, determine whether there is scheduling information of a paging message and / or the short message on the paging PDCCH according to an indication of the PEI, if the PEI indicates that there is a short message on the paging PDCCH, detect the paging PDCCH on the target paging occasion, and ignore the short message indication in the paging PDCCH, if preset bit positions of the short message indicate the second specific information, wake up to receive updated system information in a next modification period; if the PEI indicates that there is scheduling information of a paging message in the paging PDCCH, and / or all bit positions of the short message in the paging PDCCH are invalid or there is no short message in the paging PDCCH, indicate that the scheduling information of the paging message in the paging PDCCH is the scheduling information of the paging message of the target terminal, detect the scheduling information of the paging message in the paging PDCCH, and perform PDSCH reception according to the scheduling information. For a non-target terminal, when the paging PDCCH is detected, since the short message indication in the paging PDCCH is set as no scheduling information of a paging message, the non-target terminal will not perform information reception according to the scheduling information of the paging message in the paging PDCCH, and since the indication of the short message of the paging PDCCH is not recognized, the indication of the short message is ignored.

[0077] In another possible implementation, the PEI can also indicate whether system information is changed. In this possible implementation, the step of sending the paging indication information can include:

[0078] Step 1, sending the PEI, wherein the PEI indicates whether there is scheduling information of a paging message on the paging PDCCH in the target paging occasion, and / or the paging early indication information indicates whether system information is changed;

[0079] In step 2, the paging PDCCH is sent, wherein a value of a short message indication in the paging PDCCH is a third preset value, the third preset value indicates that there is no scheduling information of a paging message in the paging PDCCH, all bit positions of the short message in the paging PDCCH are invalid to indicate the first specific information and / or the second specific information, or the short message is not sent on the paging PDCCH to indicate the first specific information and / or the second specific information.

[0080] In the above possible implementation manners, the target terminal can detect the PEI, determine whether there is scheduling information of a paging message on the paging PDCCH and / or whether system information is changed according to an indication of the PEI, if the PEI indicates that there is scheduling information of a paging message, detect the paging PDCCH at a target paging occasion, and ignore a short message indication and a short message in the paging PDCCH. In the following cases, the scheduling information of the paging message in the paging PDCCH is detected, and reception of a PDSCH is performed according to the scheduling information: (1) the PEI indicates that there is scheduling information of a paging message on the paging PDCCH (2) the PEI indicates that there is scheduling information of a paging message on the paging PDCCH and system information is changed. If the PEI indicates that system information is changed, wake up at a next modification period to receive updated system information. For a non-target terminal, when the paging PDCCH is detected, because the short message indication in the paging PDCCH is set to indicate that there is no scheduling information of a paging message in the target DCI, the non-target terminal will not perform information reception according to the scheduling information of the paging message in the paging PDCCH, and because the indication of the short message in the paging PDCCH is not recognized, the indication of the short message is ignored.

[0081] It should be noted that although the implementation manners above take the PEI jointly indicating the paging information of the target terminal with the short message indication and / or the short message as an example for description, but are not limited thereto, in actual application, the PEI can also be used for separate indication. For example, the PEI is used to indicate whether system information is changed, only the terminal supporting the PEI can detect the PEI, so as to determine whether to wake up at a next modification period to update the system information according to the indication of the PEI.

[0082] By using the technical scheme provided in the embodiments of the present application, the scheduling information of the paging message of the target terminal with specific capability indicated by at least one of the PEI, the short message indication, and the short message, and / or the indication that only the target UE with specific capability is changed, so that the influence on the non-target terminal can be reduced, and unnecessary power consumption of the non-target terminal can be avoided.

[0083] Figure 3Another flowchart for illustrating the paging indication method in the embodiments of the present application is shown, the method 300 can be executed by the first terminal. In other words, the method can be executed by the software or hardware installed on the first terminal. As shown in the figure, the method can include the following steps. Figure 3

[0084] S310, receiving the paging indication information sent by the network side device, wherein the paging indication information indicates the paging information of the target terminal, and the target terminal includes a terminal with specific capability.

[0085] The network side device can send the paging indication information in the manner described in method 200, the paging indication information is the same as the paging indication information in method 200, and the network side device can indicate the paging information of the target terminal in the implementation manner described in method 200. For details, please refer to the description in method 200, which will not be repeated here.

[0086] S312, in the case that the first terminal is the target terminal, performing information reception according to the indication of the paging indication information.

[0087] In the embodiments of the present application, as described in method 200, the paging indication information can include at least one of the following:

[0088] (1) short message indication in paging PDCCH, wherein the value of the short message indication is a first preset value;

[0089] (2) preset bit of short message in paging PDCCH, wherein the value of the preset bit is a second preset value;

[0090] (3) PEI.

[0091] Optionally, as described in method 200, the specific capability can include at least one of the following:

[0092] (1) identifying the indication information that the short message indication in the paging PDCCH is the first preset value;

[0093] (2) identifying the indication information that the preset bit of the short message in the paging PDCCH is the second preset value;

[0094] (3) supporting paging early indication signal.

[0095] Optionally, as described in method 200, the paging indication information indicating the paging information of the target terminal can include at least one of the following:

[0096] (1) indicating the first specific information, wherein the first specific information is the scheduling information of the paging message of the target terminal in the paging PDCCH;​

[0097] (2) indicates the second specific information, wherein the second specific information is a notification of system information change of the target terminal only.

[0098] In a specific application, according to the different indication manners of the network side device, the first terminal performs information receiving according to the indication of the paging indication information.

[0099] The receiving can have different implementation manners. For example, in one possible implementation manner, the information receiving according to the indication of the paging indication information can include at least one of the following:

[0100] (1) If the short message indication in the paging PDCCH indicates the first specific information, the first terminal receives the corresponding paging message according to the scheduling information of the paging message in the paging PDCCH.

[0101] For example, in a specific application, when the value of the short message indication is the first preset value, the protocol can specify that the indication indicates the scheduling information of the paging message in the paging PDCCH, and then the first terminal can receive the corresponding paging message according to the scheduling information of the paging message in the paging PDCCH. For example, the scheduling information of the paging message indicates the time-frequency resource of the PDSCH, and then the first terminal can receive the PDSCH on the time-frequency resource.

[0102] (2) If the short message indication in the paging PDCCH indicates the second specific information, the first terminal acquires the updated system information in the next modification period.

[0103] For example, in a specific application, when the value of the short message indication is the first preset value, the protocol can specify that the indication indicates the system information change of the target terminal, and then the first terminal can acquire the updated system information in the next modification period according to the indication of the short message indication in the paging PDCCH.

[0104] Alternatively, when the value of the short message indication is the first preset value, the indication can indicate the system information change of the target terminal and the scheduling information of the paging message in the paging PDCCH at the same time, and then the first terminal can receive the corresponding paging message according to the scheduling information of the paging message in the paging PDCCH and acquire the updated system information in the next modification period.

[0105] In the above possible implementation manner, if the first terminal is a non-target terminal, since the first terminal cannot identify the indication information when the value of the short message indication is the first preset value, the first terminal ignores the indication of the short message indication, so that the influence on the non-target terminal can be avoided and unnecessary power consumption of the non-target terminal can be avoided.

[0106] Or, in another possible implementation, the receiving information according to the indication of the paging indication information comprises: if the preset bit of the short message in the paging PDCCH indicates the second specific information, the first terminal acquires the updated system information in the next modification period.

[0107] The value of the preset bit of the short message in the paging PDCCH can be a second preset value, for example, 1. The first terminal can determine the system information change according to the indication of the preset bit, and thus wake up in the next modification period to acquire the updated system information from the network side.

[0108] Or, in another possible implementation, the receiving information according to the indication of the paging indication information comprises:

[0109] Step 1, the first terminal detects a PEI, wherein the PEI indicates the following information: the scheduling information of the paging message in the paging PDCCH in a target paging occasion; the target paging occasion corresponds to the paging advance indication signal;

[0110] Step 2, the first terminal listens to the paging PDCCH in the target paging occasion;

[0111] Step 3, the first terminal detects a short message in the paging PDCCH according to the indication of the short message in the paging PDCCH, if the preset bit of the short message is set to the second preset value, receives the corresponding paging message according to the scheduling information of the paging message in the paging PDCCH, and acquires the updated system information in the next modification period; if the preset bit of the short message does not indicate the second specific information and the remaining bits of the short message are invalid, or no short message is detected in the paging PDCCH, the first terminal receives the corresponding paging message according to the scheduling information of the paging message in the paging PDCCH.

[0112] For example, the short message indication in the paging PDCCH indicates that there is only a short message in the paging PDCCH, the first terminal detects the short message in the paging PDCCH according to the indication of the short message indication, if the short message is detected and a preset bit of the short message is set to a second preset value, it is determined that the system information is changed, the first terminal acquires the scheduling information of the paging message in the paging PDCCH according to the indication of the PEI, and acquires the updated system information in the next modification period according to the indication of the short message.

[0113] In the above possible implementation, if the first terminal is a non-target terminal, the non-target terminal cannot detect the PEI, after detecting the target PDCCH, if it is found that the preset bit of the short message in the paging PDCCH is set to the second preset value, it cannot recognize the indication information of the value, therefore, the indication information is ignored. If it is found that all bits of the short message in the paging PDCCH are invalid or the short message is not detected, the indication of the short message is ignored.

[0114] Alternatively, in still another possible implementation, the receiving of the information according to the indication of the paging indication information can include:

[0115] Step 1, the first terminal detects the PEI, wherein the PEI can indicate at least the following information: the scheduling information of the paging message on the paging PDCCH, and the short message on the paging PDCCH;

[0116] Step 2, the first terminal detects the paging PDCCH on the target paging occasion, wherein the target paging occasion corresponds to the paging advance indication signal;

[0117] Step 3, after detecting the paging PDCCH, the first terminal ignores the short message indication in the paging PDCCH, and performs the receiving of the information according to the scheduling information of the short message and / or the paging message in the paging PDCCH; wherein the receiving of the information includes the receiving of the paging message and / or the receiving of the updated system information.

[0118] For example, if the PEI indicates that there is a short message in the paging PDCCH, the first terminal performs information reception according to the short message in the paging PDCCH, for example, if the value of a preset bit of the short message is a second preset value, the first terminal receives updated system information in the next modification period. If the PEI indicates that there is scheduling information of a paging message in the paging PDCCH, the first terminal detects the scheduling information of the paging message in the paging PDCCH, and receives the paging message according to the scheduling information.

[0119] Alternatively, in yet another possible implementation, performing information reception according to the indication of the paging indication information can include:

[0120] Step 1, the first terminal detects a PEI, the PEI indicating information of at least one of: scheduling information of a paging message on a paging PDCCH at a target paging occasion, a notification of system information change, wherein the target paging occasion corresponds to the paging early indication signal;

[0121] Step 2, if the PEI indicates that the scheduling information is on the paging PDCCH at the target paging occasion, the first terminal detects the paging PDCCH at the target paging occasion, and after detecting the paging PDCCH, ignores a short message indication and / or a short message in the paging PDCCH, and receives a paging message according to the scheduling information in the paging PDCCH; if the PEI indicates the notification of system information change, the first terminal continues to sleep at the target paging occasion, and acquires updated system information in the next modification period; if the PEI indicates the notification of system information change and indicates that the scheduling information of the paging message is on the paging PDCCH at the target paging occasion, the first terminal detects the paging PDCCH at the target paging occasion, and after detecting the paging PDCCH, ignores the short message indication and / or the short message in the paging PDCCH, receives the paging message according to the scheduling information in the paging PDCCH, and acquires updated system information in the next modification period.

[0122] According to the paging indication method provided by the embodiments of the present application, the first terminal receives scheduling information of a paging message of only a UE with a specific capability and / or system information change of only a UE with a specific capability indicated by at least one of a PEI, a short message indication and a short message used by a network side device, the first terminal with the specific capability determines the receiving behavior of the next information according to different indication manners and indication information, and a terminal without the specific capability ignores the corresponding indication information because it cannot recognize the corresponding indication information, thereby avoiding the impact on the terminal without the specific capability and unnecessary power consumption of the terminal without the specific capability.

[0123] Figure 4 Another flowchart of the paging indication method in the embodiment of the application is shown. The method 400 can be performed by the network side device and the terminal. In other words, the method can be performed by software or hardware installed on the network side device and the terminal. As shown in the method can include the following steps. Figure 4

[0124] S410, the network side device sends a paging PDCCH, wherein the bit field of the short message indication in the paging PDCCH is set to a first preset value, for example, "00", indicating that only the scheduling information of the paging message of the target terminal in the paging PDCCH.

[0125] The target terminal is a terminal with specific capabilities, for example, a terminal with corresponding capabilities of R17 and / or beyond version. The specific capabilities can be referred to in the above method 200, which will not be described here.

[0126] In this embodiment, the protocol can agree that the indication content of the bit field of the short Message indicator with the first preset value (for example, "00") is the scheduling information of the paging message of the UE with specific capabilities in the paging PDCCH.

[0127] In step S410, only the short Message indicator and the scheduling information of the paging can be set in the paging PDCCH, and the bit field of the short message is reserved.

[0128] S420, the UE listens to the PDCCH scrambled by the P-RNTI on the corresponding PO.

[0129] The corresponding PO of the UE can be preceded by a paging early indication signal (PEI), and the PEI indicates that the UE listens to the corresponding PO. Or the corresponding PO of the UE is not preceded by a paging early indication signal (PEI).

[0130] S430, the UE detects the PDCCH scrambled by the P-RNTI on the PO, and detects that the bit field of the short message indication is "00". If the UE is a UE with corresponding specific capabilities, the corresponding paging message is received according to the PDSCH scheduling information in the paging PDCCH; if the UE is a UE without corresponding specific capabilities, the indication of the bit field of the short Message indicator with the first preset value is ignored, that is, the PDSCH will not be received.

[0131] ​In an embodiment of the present application, at least one of PEI, short message indicator, short message can be used to indicate paging of only R17 and / or beyond release UEs with specific capability.

[0132] In this embodiment, an indication method is provided for indicating specific information, the indication method comprising at least one of:

[0133] using bit field of short message indicator as "00" to indicate;

[0134] using reserve bit of short message to indicate;

[0135] using PEI and / or short message indicator and / or short message to jointly indicate.

[0136] wherein the specific capability comprises at least one of:

[0137] the indication information of short message indicator "00" in paging PDCCH can be recognized to support PEI

[0138] the indication information in reserved bits in short message in paging PDCCH can be recognized to support Release 16 UEs.

[0139] the indication specific information comprises:

[0140] only the scheduling information of paging of R17 and / or beyond release UEs with corresponding capability exists in paging PDCCH;

[0141] only the system information change notification (except SIB6, SIB7 and SIB8) of R17 and / or beyond release UEs with corresponding capability exists in paging PDCCH;

[0142] the scheduling information of paging message of R17 and / or beyond release UEs with corresponding capability and the system information change notification (except SIB6, SIB7 and SIB8) exist in paging PDCCH.

[0143] the UE determines how to perform the reception of the following information according to the indication mode and the indication information.

[0144] The information that can be indicated includes:

[0145] Only the scheduling information of the paging message of the R17 and / or beyond version UE with corresponding capability in the paging PDCCH exists;

[0146] Only the system information change notification of the R17 and / or beyond version UE with corresponding capability (except SIB6, SIB7 and SIB8);

[0147] The scheduling information of the paging message of the R17 and / or beyond version UE with corresponding capability and the system information change notification (except SIB6, SIB7 and SIB8) exist in the paging PDCCH.

[0148] The information that can be indicated includes: only the system information change notification of the R17 and / or beyond version UE with corresponding capability

[0149] The specific message is jointly indicated by using the PEI and / or short message indicator and / or short message, and the UE performs the reception of the next information according to the indication method and indication content. The specific indication method is:

[0150] (1) When the indication information of the PEI is: whether the scheduling information of the paging message exists in the paging PDCCH on the PO corresponding to the PEI (that is, the paging message exists on the PO corresponding to the PEI), the indication method is: jointly indicated by using the PEI+short message indicator "10"+short message reserve bit (relative to release 16).

[0151] After detecting the PEI, the UE detects the P-RNTI scrambled PDCCH on the PO corresponding to the PEI, and performs the reception of the next information according to the short message indicator and the short message and the scheduling information of the paging.

[0152] (2) When the indication information of PEI includes: whether the paging PDCCH on the PO corresponding to the PEI has scheduling information of paging message (i.e. there is paging message on the PO corresponding to the PEI) and / or short message; the indication method is: jointly indicated by PEI+reserve bit (relative to release 16).

[0153] The UE detects the PEI and detects the P-RNTI scrambled PDCCH on the PO corresponding to the PEI, at this time the UE ignores the short message indicator in the paging PDCCH, and performs the reception of the following information according to the short message and / or the scheduling information of paging.

[0154] (3) When the indication information of PEI includes: whether the paging PDCCH on the PO corresponding to the PEI has scheduling information of paging message (i.e. there is paging message on the PO corresponding to the PEI) and / or whether there is system information change notification (except SIB6, SIB7 and SIB8).

[0155] The indication method is: jointly indicated by PEI+reserve bit (relative to release 16).

[0156] Among them, when the PEI indication information content is that the paging PDCCH on the PO corresponding to the PEI only has scheduling information of R17 and / or beyond version paging message, the UE detects the PDCCH on the PO corresponding to the PEI and UE_ID, ignores the short message indicator and short message in the paging PDCCH, and receives the paging message according to the scheduling information in the paging PDCCH.

[0157] When the PEI indication information content is the system information (except SIB6, SIB7 and SIB8) change notification, the UE does not wake up to detect the PDCCH on the PO corresponding to the PEI and UE_ID, and the UE reads the updated system information in the next modification period.

[0158] When the PEI indicates that the content of the information is a system information (except SIB6, SIB7 and SIB8) change notification and the paging PDCCH on the PO corresponding to the PEI schedules a paging message, the UE detects the PDCCH on the PO corresponding to the PEI and the UE_ID, the UE ignores the short message indicator and the short message in the paging PDCCH, and receives the paging message according to the scheduling information in the paging PDCCH; and reads the updated system information in the next modification period.

[0159] In this embodiment, the indication mode and the content of the indication information can be agreed by a protocol.

[0160] Figure 5 Another flowchart of a paging indication method in the embodiment of the application is shown, the method 500 can be executed by a network side device and a terminal. In other words, the method can be executed by software or hardware installed on the network side device and the terminal. As shown in the figure, the method can include the following steps. Figure 5

[0161] S510, the network side device sends a paging PDCCH, wherein the bit field of the short message indication in the paging PDCCH is set to a first preset value, for example, "00", indicating that only the system information of the target terminal is changed.

[0162] Wherein, the target terminal is the same as the target terminal in the method 200, and the specific description can be referred to the description in the method 200, which will not be repeated here.

[0163] In this embodiment, the protocol can agree that when the bit field of the short message indication is the first preset value, it indicates that only the system information of the target terminal is changed.

[0164] In S510, only the short message indication can be set in the paging PDCCH, and the bit field of the short message and the bit field corresponding to the scheduling information of the paging are reserved.

[0165] S520, the UE listens to the P-RNTI scrambled PDCCH on the corresponding PO.

[0166] Wherein, S520 is the same as S420, and the specific description can be referred to S520.

[0167] ​S530, if the terminal is a terminal with the corresponding specific capability, the terminal acquires the updated system information in the next modification period, if the terminal is a terminal without the corresponding specific capability, the terminal ignores the indication of the short message indication, that is, will not wake up to acquire the updated system information in the next modification period.

[0168] In another implementation, the indication information of the short message indication with the first preset value can also be: only the short message of the target terminal in the paging DCI of the paging PDCCH, and only the short message indication and the short message are set in the paging PDCCH; and the bit field corresponding to the scheduling information of the paging message is reserved.

[0169] The preset bit of the short message can have a second preset value, for example, any bit in the reserved bit in the bit field of the short message in the DCI format 0_1, for example, the 4th bit in the bit field of the short message. If the value of the bit is the second preset value, for example, 1, it indicates that only the system information of the target terminal is changed, and in S530, if the terminal is a terminal with the corresponding specific capability, the terminal acquires the updated system information in the next modification period according to the indication of the short message, if the terminal is a terminal without the corresponding specific capability, the terminal ignores the indication of the short message, that is, will not wake up to acquire the updated system information in the next modification period.

[0170] Figure 6 Another flowchart of the paging indication method in the embodiment of the application is shown, which can be executed by the network side device and the terminal. In other words, the method can be executed by the software or hardware installed on the network side device and the terminal. As shown in the figure, the method can include the following steps. Figure 6

[0171] S610, the network side device sends a paging PDCCH, wherein the bit field of the short message indication in the paging PDCCH is set to a first preset value, for example, "00", indicating the notification of the system information change (for example, the system information change except SIB6, SIB7 and SIB8) of only the target terminal and the scheduling information of the paging message of only the target terminal in the paging PDCCH.

[0172] In this embodiment, only the short message indicator and the scheduling information of the paging are set in the paging PDCCH, and the bit field of the short message is reserved.

[0173] S620, same as S420.

[0174] ​S630, if the terminal is a UE with the specific capability, receiving the corresponding paging message according to the scheduling information indicated by the paging PDCCH and acquiring the updated system information in the next modification period; if the terminal is not a UE with the corresponding capability, ignoring the indication of the short message indication, i.e., not receiving the corresponding paging message according to the scheduling information indicated by the paging PDCCH and not acquiring the updated system information in the next modification period.

[0175] Alternatively, in another implementation, the bit field of the short message indication in the paging PDCCH is set to a first preset value, e.g., "00", indicating that only the scheduling information of the paging message of the target terminal and the short message in the paging PDCCH. The paging PDCCH sets the short message indication, the short message, and the scheduling information of the paging message. The value of the preset bit of the short message can be a second preset value, e.g., any bit in the reserved bit of the bit field of the short message in the DCI format 0_1, e.g., the 4th bit in the bit field of the short message. If the value of the bit is the second preset value, e.g., 1, it indicates that only the system information of the target terminal is changed. In S630, if the terminal is a terminal with the corresponding specific capability, the corresponding paging message is received according to the scheduling information indicated by the paging PDCCH, and the updated system information is acquired in the next modification period according to the indication of the short message. If the terminal is not a terminal with the corresponding specific capability, the terminal ignores the indication of the short message indication and the short message, i.e., does not receive the corresponding paging message according to the scheduling information indicated by the paging PDCCH, and does not acquire the updated system information in the next modification period.

[0176] Figure 7 Another flowchart of the paging indication method in the embodiment of the present application is shown. The method 700 can be executed by the network side device and the terminal. In other words, the method can be executed by software or hardware installed on the network side device and the terminal. As shown in the figure, the method can include the following steps. Figure 7

[0177] S710, the network side device sends a paging PDCCH, wherein the short message indication of the paging PDCCH indicates that only the short message (i.e., without the scheduling information of the paging message) in the paging PDCCH, and the value of the preset bit of the short message of the paging PDCCH is set to a second preset value, indicating the notification of the system information change of the target terminal only.

[0178] ​In this embodiment, the network side device only wants to indicate the system information update notification to the target UE, and sets two parts in the paging PDCCH sent by the network device: short message indication and short message. Among them, the short message indication indicates that there is only a short message in the paging PDCCH, for example, the bit field of the short message indication can be set to "10", and the value of the preset bit of the short message is a second preset value, for example, the short message uses any one of the reserved bits (for example, the 4th bit) relative to Release 16 to indicate the system information update notification of the target UE.

[0179] S720, same as S420.

[0180] S730, the terminal detects the P-RNTI scrambled PDCCH on the PO, and detects that the bit field of the short message indication is the first preset value, and the preset bit is set in the detected short message, that is, the value of the bit other than the preset bit in the short message is an invalid value. If the terminal is a UE with corresponding capability, the updated system information is acquired in the next modification period; if the terminal is a UE without corresponding capability, the indication of the short message is ignored.

[0181] Figure 8 Another flowchart of the paging indication method in the embodiment of the application is shown, and the method 800 can be executed by the network side device and the terminal. In other words, the method can be executed by the software or hardware installed on the network side device and the terminal. As shown in the figure, the method can include the following steps. Figure 8

[0182] S810, the network side device sends a PEI, wherein the PEI indicates whether there is scheduling information of a paging message in the paging PDCCH on the PO corresponding to the PEI.

[0183] In this embodiment, when the network side device only pages the target terminal (for example, a UE with a specific capability of R17 and / or beyond version), the network side device sends a PEI to indicate that there is scheduling information of a paging message in the paging PDCCH on the PO corresponding to the PEI.

[0184] S820, the terminal listens to the PEI at the corresponding PEI occasion, and the PEI is used to indicate the detection parameter of the UE detecting paging, which is used to determine the detection manner of the UE detecting paging.

[0185] Optionally, the detection parameter can include:

[0186] a) whether the UE listens to the P-RNTI scrambled paging PDCCH on the paging occasion (PO) associated with the terminal;

[0187] ​If the PEI does not carry packet information, the UE determines whether to monitor the paging PDCCH on the PO associated with the terminal according to the PEI. If the PEI carries packet information, the UE determines whether the PEI is used to indicate the group in which the UE is located according to the packet information carried in the PEI. For example, if the PEI indicates the group in which the UE is located, the UE further determines whether to monitor the paging PDCCH on the PO associated with the terminal according to the PEI; if the PEI does not indicate the group in which the UE is located, the UE ignores the PEI.

[0188] b) whether the paging PDCCH on the PO corresponding to the PEI has scheduling information of a paging message. For example, the PEI has an additional 1 bit of indication information indicating whether the paging PDCCH has scheduling information of a paging message.

[0189] S830, the UE detects the PEI, and the PEI indicates that the paging PDCCH has scheduling information of a paging message, the UE monitors the paging PDCCH on the corresponding PO.

[0190] S840, the network side device sends the paging PDCCH on the PO corresponding to the PEI.

[0191] The paging PDCCH is provided with short message indication, a short message, and scheduling information of a paging message, wherein the short message indication indicates that only the short message (i.e., no scheduling information of a paging message) exists in the target DCI (i.e., the DCI on the paging PDCCH), for example, the bit field of the short message indication is "10". The value of a preset bit of the short message is a second preset value, for example, the value of any reserved bit in the short message is the second preset value, i.e., indicating only the notification of the system information change of the target terminal, and the values of other bits of the short message remain unchanged. Alternatively, other reserved bits in addition to the above preset bit are provided to indicate that the system information has no change, or any bit in the short message is not provided (i.e., the value is invalid).

[0192] S850, the UE monitors the paging PDCCH on the corresponding PO, and determines the reception of the short message indication and the short message on the paging PDCCH according to the detection.

[0193] If the short message indication indicates that only the short message exists in the paging PDCCH, and the preset bit of the short message is the second preset value, if the UE is a UE with a corresponding specific capability, the UE receives the corresponding paging message according to the scheduling information of the paging message indicated by the paging PDCCH, and receives the updated system information in the next modification period.

[0194] If the short message indication indicates only the short message in the paging PDCCH, but the short message does not have any bit set to 1 except the preset bit field (for example, 5-8 bits) set to 1, if the UE is a UE with a corresponding specific capability, the UE receives the corresponding paging message according to the scheduling information indicated by the paging PDCCH.

[0195] If the UE is a UE without the corresponding capability, the UE cannot identify the indication of the short message, and thus ignores the indication information of the short message.

[0196] Figure 9 Another flowchart of a paging indication method in the embodiments of the present application is shown, and the method 900 can be performed by a network side device and a terminal. In other words, the method can be performed by software or hardware installed on the network side device and the terminal. As shown in the method can include the following steps. Figure 9

[0197] S910, the network side device sends a PEI, wherein the PEI indicates whether there is scheduling information of a paging message and / or a short message in a paging PDCCH on a PO corresponding to the PEI.

[0198] S920, the terminal listens to the PEI at a corresponding PEI occasion, and the PEI is used to indicate a detection parameter of the UE for detecting paging, and the detection parameter is used to determine a detection manner of the UE for detecting paging.

[0199] The detection parameter is different from that of S820 in that the detection parameter includes indication of whether the paging PDCCH on the PO corresponding to the PEI has a short message and / or scheduling information of paging. For example, there are additional 2 bits of indication information in the PEI, respectively indicating whether the paging PDCCH has scheduling information of a paging message and whether the paging PDCCH has a short message.

[0200] S930, the UE detects the PEI, and the PEI indicates that the paging PDCCH has scheduling information of a paging message and / or a short message, and the UE listens to the paging PDCCH at a corresponding PO.

[0201] S940, the network side device sends a paging PDCCH on a PO corresponding to the PEI.

[0202] When the PEI indicates that the paging PDCCH on the PO only has a short message, the paging PDCCH has a short message indication and a short message, and a bit field related to scheduling information of a paging message is reserved; for example, the bit field of the short message indication is "10"; the preset bit of the short message has a second preset value, for example, a reserved bit relative to Release 16. ​

[0203] When the PEI indicates that there is only paging scheduling information on the PO, the short message indication, the short message and the scheduling information of the paging message are set in the paging PDCCH; wherein the bit field of the short message indication indicates that there is a short message in the paging PDCCH, for example, “10”; the short message sets the reserved bit relative to Release 16 (except for the preset bit) to indicate that there is no change in the system information, or any bit in the short message is not set.

[0204] When the PEI indicates that there is paging scheduling information and a short message on the PO, the short message indication, the short message and the scheduling information of the paging message are set in the paging PDCCH; wherein the bit field of the short message indication indicates that there is a short message in the paging PDCCH, for example, “10”; the preset bit of the short message is set to the second preset value. For example, the short message sets the reserved bit (for example, the 4th bit) relative to Release 16.

[0205] S950, the UE monitors the paging PDCCH in the corresponding PO, and determines the reception of the short message indication and the information determined according to the short message on the paging PDCCH.

[0206] If the UE has the corresponding capability, the short message indication is ignored; the information reception action determined according to the short message is: if the short message does not set any bit to the valid value (for example, 1) or the other reserved bits (for example, the 5th-8th bits) except the preset bit are set to 1, the UE determines whether to receive the corresponding paging message according to the scheduling information indicated by the paging PDCCH according to the PEI indication; if the preset bit of the short message is set to the second preset value, the updated system information is received in the next modification period.

[0207] If the UE is a UE without the corresponding capability, if the short message does not set any bit to 1 or the reserved bit of the short message is set to 1, the indication information is ignored.

[0208] In a possible implementation, the PEI can also indicate whether there is scheduling information of paging PDCCH on the PO corresponding to the PEI and / or whether there is a notification of system information change (except SIB6, SIB7 and SIB8). If the network side device only wants to indicate the notification of system information update to the target UE and / or the network side device wants to find the target UE through the paging message, at least one of the short message indication, the short message, the scheduling information of the paging message in the paging PDCCH sent by the network side device is set in S940. Among them, the bit field of the short message indication is set to "10", the short message indicates that there is no change relative to the reserved bit of Release 16, or none of the bits in the short message is set. In S950, when the PEI indicates that there is scheduling information, the target UE (for example, R17 and / or a UE with a corresponding capability of a higher release version) listens to the paging PDCCH on the PO corresponding to the PEI, ignores the short message indication and / or the short message, and receives the corresponding paging message according to the scheduling information indicated by the Paging PDCCH. When the PEI indicates system information change, the target UE does not listen to the PO corresponding to the PEI, that is, the UE does not wake up to detect the PO corresponding to the PEI and the UE_ID, and obtains the updated system information in the next modification period. When the PEI indicates that there is scheduling information of the paging message on the PO corresponding to the PEI and system information change, the target UE listens to the paging PDCCH on the PO corresponding to the PEI, ignores the short message indication and / or the short message, and receives the corresponding paging message according to the scheduling information indicated by the Paging PDCCH, and obtains the updated system information in the next modification period. For non-target UEs (that is, UEs without a corresponding capability of 4), after detecting the paging PDCCH, it is found that the short message sets the reserved bits or none of the bits is set to 1, and then the indication information of the short message indication is ignored.

[0209] It should be noted that the paging indication method provided in the embodiments of the present application can be executed by a paging indication device, or a control module in the paging indication device for executing the paging indication method. In the embodiments of the present application, the paging indication device executes the paging indication method as an example to illustrate the paging indication device provided in the embodiments of the present application.

[0210] Figure 10 A structural schematic diagram of the paging indication device according to the embodiments of the present application is shown in FIG. 1. Figure 10As shown, the apparatus 1000 can include a determining module 1001 and a sending module 1002.

[0211] In the embodiments of the present application, the determining module 1001 is configured to determine paging information of a target terminal, wherein the target terminal includes a terminal with a specific capability; and the sending module 1002 is configured to send paging indication information, wherein the paging indication information indicates the paging information of the target terminal.

[0212] In a possible implementation, the paging indication information includes at least one of the following:

[0219] support of the PEI.

[0220] In a possible implementation, the first preset value is 00; and / or the preset bit is a bit that cannot be identified by a terminal without the specific capability, and the second preset value is 1.

[0221] In a possible implementation, the paging indication information indicating the paging information of the target terminal includes at least one of the following:

[0222] indication of first specific information, wherein the first specific information is scheduling information of only a paging message of the target terminal in the paging PDCCH;

[0223] indication of second specific information, wherein the second specific information is a notification of a system information change of only the target terminal.
