[0045] As an example and not a limitation, in the embodiments of the present application, wearable devices may also be referred to as wearable smart devices, which are a general term for wearable devices that are intelligently designed and developed by applying wearable technology to daily wear, such as glasses, gloves, watches, clothing, and shoes. A wearable device is a portable device that is worn directly on the body or integrated into the user's clothes or accessories. Wearable devices are not only hardware devices, but also achieve powerful functions through software support, data interaction, and cloud interaction. Broadly speaking, wearable smart devices include full-featured, large-sized, and independent of smartphones to achieve complete or partial functions, such as smart watches or smart glasses, as well as devices that only focus on a certain type of application function and need to be used in conjunction with other devices such as smartphones, such as various types of smart bracelets and smart jewelry for vital sign monitoring.

[0046] In addition, in the embodiment of the present application, the terminal device 110 can also be a terminal device in the Internet of Things (IoT) system. IoT is an important part of the future development of information technology. Its main technical feature is to connect objects to the network through communication technology, thereby realizing an intelligent network that interconnects people and machines and things.

[0047] The various terminal devices 110 introduced above, if located on a vehicle (eg placed in or installed in a vehicle), can be considered as vehicle-mounted terminal devices, which are also called on-board units (OBU).

[0048] In the embodiment of the present application, the access network device 120 is a device in a radio access network ((radio) access network, (R)AN), or in other words, a RAN node that connects a terminal device to a wireless network, or a device in a next generation radio access network (NG-RAN).

The cell may be a cell corresponding to the access network device 120 (for example, a base station). The cell may belong to a macro base station or a base station corresponding to a small cell. The small cells here may include: metro cells, micro cells, picocells, femto cells, etc. These small cells have the characteristics of small coverage and low transmission power, and are suitable for providing high-speed data transmission services.

[0051] The core network device 130 is used to manage one or more access network devices 120. For example, the core network device 130 is used to send information used by the access network device to send a paging message to the access network device 120.

[0052] It should be understood that Figure 1 A core network device 130, an access network device 120 and a terminal device 110 are shown by way of example. In some embodiments, the communication system may include other numbers of core network devices, access network devices or terminal devices, which is not limited in the embodiments of the present application.

Figure 1 Taking the communication system shown as an example, the communication equipment may include a terminal device 110 with communication functions, an access network device 120 and a core network device 130, etc., which is not limited in the embodiments of the present application.

[0054] It should be understood that the terms "system" and "network" are often used interchangeably herein.

[0057] The term "and / or" in this article is only a description of the association relationship of the associated objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0058] The terms used in the implementation mode of this application are only used to explain the specific embodiments of this application, and are not intended to limit this application. The terms "first", "second", "third" and "fourth" in the specification and claims of this application and the drawings are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions.

[0059] It should be understood that the "indication" mentioned in the embodiments of the present application can be a direct indication, an indirect indication, or an indication of an association relationship. For example, A indicates B, which can mean that A directly indicates B, for example, B can be obtained through A; it can also mean that A indirectly indicates B, for example, A indicates C, and B can be obtained through C; it can also mean that there is an association relationship between A and B.

[0060] In the description of the embodiments of the present application, the term "corresponding" may indicate a direct or indirect correspondence between two items, or an association relationship between the two items, or a relationship between indication and being indicated, configuration and being configured, and the like.

[0061] In order to better understand the embodiments of the present application, the relevant contents of the low power wake-up signal (LowPower-Wake up Signal, LP-WUS) in the existing NR system are introduced.

[0062] The 3rd Generation Partnership Project (3GPP) will start the research work of introducing LP-WUS in mobile cellular systems in Rel-18. In order to reduce the reception activity of terminal equipment in standby mode, the radio frequency (RF) and baseband (modem) modules are truly turned off, thereby greatly reducing the power consumption of communication reception. This can be achieved by introducing a near "zero" power receiver in the receiving module of the terminal equipment. This near "zero" power receiver does not require complex RF module signal detection (such as amplification, filtering, quantization, etc.) and modem signal processing, but only relies on passive matching filtering and signal processing with low power consumption. On the base station side, by triggering the wake-up signal on demand, the near "zero" power receiver can be activated to obtain the activation notification, thereby triggering a series of processes inside the terminal equipment, such as turning on the RF transceiver and baseband processing modules.

[0063] The wake-up signal may be LP-WUS, which is received by a low power receiver (Low Power-Wake up Radio, LP-WUR). Figure 2 As shown, the terminal device includes two modules, the first module is a main communication module for sending and receiving mobile communication data, and the second module is a low-power wake-up receiving module for receiving the LP-WUS sent by the sender to wake up the main communication module of the receiving end. Optionally, the second module can also receive a low-power beacon signal sent by the sender to provide time reference information and other information for receiving the low-power wake-up signal, and can also provide wake-up link management.

[0064] like Figure 2 As shown, the terminal device turns on the second module in the energy-saving state to listen to LP-WUS and turns off the first module. The first module is always in the off state when it is not awakened by the second module, and does not send or receive data. When downlink data arrives, the second module detects the LP-WUS sent by the sender, and the LP-WUS contains the information of the terminal device, then the second module triggers the first module to switch from the off state to the working state to receive and send data. The second module can be turned on continuously or discontinuously, and the second module can receive LP-WUS when it is turned on.

[0065] Figure 3 A schematic diagram of the basic format of LP-WUS is shown in FIG. Figure 3 As shown, the LP-WUS may include a preamble and data, wherein the preamble field may be used for at least one of LP-WUS detection, synchronization, and data rate determination, and the data field is used to carry data.

[0066] In some embodiments, LP-WUS may be some relatively simple on-off keying (OOK) signals, so that the receiver can obtain the wake-up notification through simple energy detection and subsequent possible sequence detection and other identification processes. Figure 4A A schematic diagram of an OOK signal is shown.

[0067] As an implementation method, an orthogonal frequency division multiplexing (OFDM) signal modulation method can be used to generate OOK signals, for example, the transmission or non-transmission of an OFDM modulated sequence represents the on / off switch in the time domain. OOK signals can be received using a receiver with lower power consumption, but such receivers have poor reception performance and poor coverage.

[0068] Optionally, different sequences can be used to carry information on the modulation-ON OFDM modulation sequence. For example, two sequences represent 0 and 1 information respectively, or four signals represent 00, 10, 10, 11 information respectively. Figure 4B As shown in the figure, part of the information is carried through OOK modulation (where the OOK bit is 1), and the other part of the information is carried through an ON level OFDM sequence (where the OFDM bit is 4). Since a receiver with OFDM signal reception capability is required to demodulate the OFDM sequence, generally speaking, such receivers have better demodulation performance, that is, better than low-power receivers that can only demodulate OOK signals.

[0069] In order to better understand the embodiments of the present application, the relevant contents of the paging early indication (PEI) in the existing NR system are introduced.

[0070] For terminal devices in the idle state, it is necessary to measure the synchronization signal block (Synchronization Signal / PBCH Block, SSB) and receive paging in each paging cycle. Paging reception includes the terminal device monitoring the paging physical downlink control channel (PDCCH) on its associated paging opportunity (Paging Occasion, PO), and further receiving the paging physical downlink shared channel (Physical Downlink Shared Channel, PDSCH) after monitoring the paging PDCCH. Among them, multiple terminal devices will be associated with one PO, so the terminal device may be mistakenly awakened to monitor the paging PDCCH and paging PDSCH because other terminal devices in the same group are paged, and the terminal device will not go to sleep until it is confirmed that the paging PDSCH does not have the terminal device identification of the terminal device. Therefore, since the terminal device monitors the paging PDCCH / PDSCH in each paging cycle, and since there are multiple associated terminal devices in a PO group, the terminal device may be mistakenly awakened, resulting in unnecessary monitoring power consumption of the terminal device.

[0071] In order to reduce the power consumption of terminal devices, the R17 standard further introduces PDCCH based PEI. Before receiving the paging PDCCH, the terminal device first receives PEI and determines whether it needs to monitor the subsequent paging PDCCH based on the content indicated in PEI. If PEI indicates that the terminal device does not receive the paging PDCCH, the terminal device does not need to detect one or more SSBs between PEI and PO, thereby saving power consumption.

[0072] In addition, PEI also has the function of further grouping and indicating multiple terminal devices of a PO. For example, PEI is associated with and indicates a PO. The PEI carries 8 bits of information for further grouping and indicating multiple terminal devices of the PO. Exemplarily, each bit can correspond to a subgroup, that is, the 8 bits can indicate whether the 8 subgroups need to monitor subsequent paging PDCCHs. Based on this, the terminal devices associated with a PO can be further divided into 8 subgroups, and PEI indication is performed for each subgroup, which can reduce the probability of false wake-up of the terminal device, thereby reducing the paging monitoring power consumption of the terminal device. Exemplarily, the indication field of PEI can be as follows: Figure 5 As shown in the figure, one PEI indicates 4 POs (index 0 to 3), and each PO can be divided into a maximum of 8 subgroups (subgroup 0 to subgroup 7).

[0073] In addition, PEI also defines two grouping methods, one is a grouping method based on terminal equipment identification (such as UE_ID), and the other is a grouping method based on CN control.

[0074] In the grouping method based on the terminal device identification, the access network device can group multiple terminal devices. This grouping method can also be called the grouping method controlled by the access network device. Optionally, the access network device can group according to the identification of each terminal device. Specifically, the access network device can calculate the group identification ID (such as the group number) corresponding to each terminal device according to the identification of each terminal device, for example, the terminal device identification can be modulo the group number. Each terminal device can also obtain its own group ID according to the same calculation method as the access network device. Optionally, the terminal device can support the grouping method based on the terminal device identification by default.

[0075] In the grouping method based on CN control, the core network device can group multiple terminal devices corresponding to one PO. The core network device can notify each terminal device of the group ID to which each terminal device belongs, and each terminal device can save the group ID assigned by the core network device to itself.

[0076] When a cell supports both the grouping method based on terminal device identification and the grouping method based on CN control, the grouping ID obtained based on the grouping method based on CN control (i.e., CN grouping ID) is in front, and the grouping ID obtained based on the grouping method based on terminal device identification (i.e., terminal device identification grouping ID) is in the back. For example, a cell has 6 terminal groups in total, the number of groups based on the grouping method based on terminal device identification is 4, and the number of groups based on the grouping method based on CN control is 2. Then the CN-based grouping ID is 0, 1, and the terminal device identification-based grouping ID is 2, 3, 4, 5. Therefore, for the terminal device identification grouping ID, the terminal device identification and the grouping number are modulo, and the grouping number based on the CN control grouping needs to be added. For example, if the terminal device identification and the grouping number are 0 after modulo, then add the grouping number 2 based on the CN control grouping method, and you can get a terminal device identification grouping ID of 2.

[0077] At present, in the related technology, the network side can configure LP-WUS to reduce the power consumption of the terminal device. In the energy-saving state, the terminal device turns on the low-power wake-up receiving module to listen to LP-WUS and turns off the main communication module. When the main communication module is not awakened, it is always in the closed state and does not send or receive data. When downlink data arrives, the low-power wake-up receiving module in the terminal device receives LP-WUS, and the low-power wake-up receiving module triggers the main communication module to switch from the closed state to the working state to receive and send data. Due to the limited load (payload) of LP-WUS, it is impossible to indicate wake-up for each terminal device separately. Therefore, when LP-WUS is used to wake up a terminal device, multiple terminal devices may be awakened, resulting in a high false awakening rate of the terminal device. Therefore, when LP-WUS is configured on the network side, how to reduce the probability of false awakening of terminal devices needs to be solved urgently.

[0078] In order to solve the above technical problems, the embodiment of the present application uses LP-WUS to indicate the terminal group where the terminal device that needs to be awakened is located, so as to realize the awakening of multiple terminal device group indications. Specifically, the terminal device can determine the group ID of the terminal group to which it belongs, and receive LP-WUS from the access network device. LP-WUS can indicate the target group ID of the target terminal group that needs to be awakened. The terminal device determines whether to be awakened based on its group ID and the target group ID to reduce the probability of terminal device being awakened by mistake. Terminal devices outside the terminal group corresponding to the target group ID may not be awakened, thereby saving power consumption of some terminal devices.

[0079] The technical solution of the present application is described in detail below through specific embodiments.

[0080] Figure 6 FIG. 2 is a schematic flow chart of a communication method 200 according to an embodiment of the present application. Figure 6 As shown, the communication method 200 may include at least part of the following steps S210 to S240:

[0081] S210, the terminal device determines a first group ID of a first terminal group to which the terminal device belongs.

[0082] Specifically, multiple terminal devices within a cell can be divided into multiple terminal groups (i.e., subgroups), and each terminal group can include at least one terminal device. Optionally, the multiple terminal devices can be multiple terminal devices associated in a PO, without limitation. Each terminal group can correspond to a group ID, and the group ID can be, for example, the group number of the terminal group, which is not limited in this application. In an embodiment of the present application, LP-WUS can indicate whether to wake up for each terminal device group to reduce the false wake-up rate of the terminal device and further reduce the power consumption of the terminal device.

[0083] In some embodiments, the terminal device may determine the first grouping ID according to a target grouping method, wherein the target grouping method includes at least one of a first grouping method based on a terminal device identifier (UE_ID) and a second grouping method controlled by a core network (CN) device.

[0084] In the first grouping mode, the access network device can group multiple terminal devices. The first grouping mode can also be called the grouping mode controlled by the access network device (RAN). Optionally, the access network device can group according to the identifier of each terminal device. Specifically, the access network device can calculate the grouping ID (such as the group number) corresponding to each terminal device according to the identifier of each terminal device, for example, the identifier of the terminal device can be modulo the number of grouping groups. Each terminal device can also obtain its own grouping ID according to the same calculation method as the access network device. Optionally, the terminal device can support the first grouping mode by default.

[0085] Optionally, the grouping obtained based on the first grouping method may also be called a RAN grouping, a terminal equipment identification grouping, a UE_ID grouping, etc., which is not limited in this application.

[0086] In the second grouping mode, the core network device can group multiple terminal devices corresponding to one PO. The core network device can notify each terminal device of the group ID to which each terminal device belongs, and each terminal device can save the group ID assigned by the core network device to itself. Optionally, the core network device can also notify the access network device of the group ID to which the terminal device belongs.

[0087] Optionally, the grouping obtained based on the second grouping method may also be referred to as a CN grouping, which is not limited in this application.

[0088] Optionally, the target grouping method may include the following three situations:

[0089] Case 1: the target grouping method only includes the first grouping method but does not include the second grouping method.

[0090] Case 2: The target grouping method includes a first grouping method and a second grouping method.

[0091] Case 3: the target grouping method only includes the second grouping method but does not include the first grouping method.

[0092] It should be noted that the target grouping method includes a first grouping method including two cases, namely, case 1 and case 2 described above; the target grouping method includes a second grouping method including two cases, namely, case 2 and case 3 described above.

[0093] Exemplarily, Case 1 and Case 2 are applicable to the scenario where the access network device supports the first grouping mode, or the access network device can provide the terminal device with the configuration information corresponding to the first grouping mode. In this scenario, the access network device may also support the second grouping mode, or may not support the second grouping mode, without limitation. Optionally, the configuration information corresponding to the first grouping mode may include at least one of the number of LP-WUS groups based on the first grouping mode, the number of LP-WUS groups, and broadcast parameters for determining the group ID of the terminal device, etc., which are not limited in this application.

[0094] Exemplarily, situation 3 is applicable to a scenario in which the access network device only supports the second grouping mode, or the access network device does not support the first grouping mode, or the access network device does not provide configuration information corresponding to the first grouping mode.

[0095] In some embodiments, when the target grouping mode includes a first grouping mode, the first grouping ID can be determined based on the first terminal device identifier and the first grouping number of the terminal device; wherein the first grouping number can be the maximum number of groups based on the first grouping mode corresponding to the LP-WUS, or the number of groups based on the first grouping mode corresponding to the LP-WUS, or the number of groups corresponding to the LP-WUS, or the number of bits corresponding to the first indication information in the LP-WUS.

[0096] Exemplarily, the first number of groups can be expressed as Y. In both cases 1 and 2 above, Y can be the number of groups based on the first grouping method corresponding to LP-WUS, or the maximum number of groups based on the first grouping method corresponding to LP-WUS, and the two can be equivalent descriptions.

[0097] It should be noted that in some embodiments of the present application, the number of groups and the maximum number of groups can represent the same or similar meanings, and in some implementations, the two can be replaced with each other. For example, the first number of groups can be replaced with the first maximum number of groups, the second number of groups can be replaced with the second maximum number of groups, the third number of groups can be replaced with the third maximum number of groups, and the fourth number of groups can be replaced with the fourth maximum number of groups, etc., and the present application does not limit this.

[0098] Optionally, in the above situation 1, the first grouping number Y is the grouping number corresponding to LP-WUS, and the grouping number based on the second grouping method corresponding to LP-WUS is 0.

[0099] Optionally, in the above situation 1, the first group number Y can be the number of bits M corresponding to the first indication information in the LP-WUS. The first indication information is used for grouping, and each of the M bits of the first indication information corresponds to a terminal group, which is used to indicate whether the terminal device in the corresponding terminal group needs to be awakened. Alternatively, each of the M bits of the first indication information corresponds to the group ID of a terminal group, which is used to indicate whether the terminal device in the terminal group corresponding to the corresponding group ID needs to be awakened. In this case, Y=M.

[0100] For example, when the number of bits corresponding to the first indication information is M=8, the first number of groups Y can be 8, and each of the 8 bits in the first indication information corresponds to a terminal group (group ID), which is used to indicate whether the terminal device in the corresponding terminal group needs to be awakened.

[0101] In some embodiments, for the above situation 1, that is, when the target grouping method only includes the first grouping method but not the second grouping method, the first grouping ID can be determined according to the first terminal device identifier and the first group number of the terminal device.

[0102] Exemplarily, the first terminal device identifier P of the terminal device may be subjected to a modulo operation on the first group number Y to obtain a group ID corresponding to the terminal device, which may be specifically expressed as the following formula:

[0103] SubgroupID=P mod Y (1)

[0104] Here, SubgroupID represents the group ID.

[0105] In some embodiments, for the above situation 2, that is, when the target grouping method includes the first grouping method and the second grouping method, the first grouping ID can be determined according to the first terminal device identifier of the terminal device, the first group number and the grouping ID starting value corresponding to the first grouping method.

[0106] Exemplarily, the first terminal device identifier P of the terminal device may be subjected to a modulo operation on the first group number Y, and the sum of the operation result and the group ID starting value S is determined as the group ID corresponding to the terminal device, which may be specifically expressed as the following formula:

[0107] SubgroupID=P mod Y + S (2)

[0108] Optionally, the group ID start value can be determined according to the number of groups based on the second grouping method corresponding to the LP-WUS. The number of groups based on the second grouping method corresponding to the LP-WUS is, for example, the number of CN groups. For example, when the number of groups in the second grouping method corresponding to the LP-WUS (i.e., the number of CN groups) is 2, S=2. In this way, the CN group ID corresponding to the LP-WUS can be placed in front of the terminal device identification group ID corresponding to the LP-WUS.

[0109] For example, multiple terminal devices in a cell are divided into 6 terminal groups, the groups corresponding to the first grouping method (RAN groups, or terminal device identification groups) occupy 4 groups, and the groups corresponding to the second grouping method (CN groups) occupy 2 groups, then the CN group IDs can be 0, 1, and the terminal device identification group IDs can be 2, 3, 4, 5. At this time, the first terminal device identification is modulo the first group number and then added to the CN group number (S=2) to obtain the terminal device identification group ID, that is, the group ID based on the first grouping method.

[0110] In one embodiment, when there is no group corresponding to the second grouping mode (ie, CN group), S=0, and formula (2) is simplified to formula (1).

[0111] It should be noted that when the group ID starts from 0, the group ID of the terminal group to which the terminal device belongs can be directly obtained according to the above formula (1) or formula (2). When the group ID starts from 1, the group ID of the terminal group to which the terminal device belongs can be obtained by adding 1 to the calculation result of the above formula (1) or formula (2).

[0112] In some embodiments, in method 200, the second terminal device identifier of the terminal device may be determined according to the mobile user identifier of the terminal device and the first parameter X; and the first terminal device identifier may be determined according to the second terminal device identifier and the second parameter.

[0113] Exemplarily, the mobile user identity can be a globally unique identifier assigned by the communication system to the terminal device, which can be used to uniquely identify the terminal device. As an example, the mobile user identity can be a 5G Global Unique Temporary UE Identity (5G-GUTI), or a 5G temporary mobile subscription identifier (Temporary Mobile Subscription Identifier, TMSI), or a 5G-S-TMSI, etc., without limitation.

[0114] Specifically, the mobile user identity of the terminal device may be modulo the first parameter X to obtain the second terminal device identity UE_ID. Taking the mobile user identity as 5G-S-TMSI as an example, the second terminal device identity UE_ID may be expressed as: 5G-S-TMSI mod X. Here, the second terminal device identity UE_ID may be the portion of the mobile user identity used by LP-WUS to determine the grouping ID based on the first grouping method.

[0115] Optionally, the number of bits of the second terminal device identifier UE_ID is log2Y, where Y is the first grouping number mentioned above.

[0116] For example, when the first group number Y is 8, the number of bits of the second terminal device identifier UE_ID is 3. That is, by performing a modulo operation on the mobile user identifier of the terminal device and the first parameter X, 3 bits of the mobile user identifier can be obtained as the second terminal device identifier UE_ID.

[0117] In some embodiments, the first parameter X may be determined according to one of the following methods 1 and 2.

[0118] Mode 1: In a non-extended discontinuous reception mode (eDRX) scenario, the first parameter X is the product of 8192 and the first number of groups; or, in an eDRX scenario, the first parameter X is the product of 32798 and the first number of groups.

[0119] Specifically, in the grouping method based on the terminal equipment identifier (UE_ID) corresponding to PEI, the partial UE_ID used for PEI to determine the grouping ID based on the terminal equipment identifier can be determined according to 5G-S-TMSI mod X'. In order to make the above-mentioned second terminal equipment identifier UE_ID different from the partial UE_ID that determines the grouping ID based on the terminal equipment identifier grouping method of PEI, the above-mentioned first parameter X can be obtained according to the product of X' and the first grouping number Y. Since it has been defined in the protocol that in non-eDRX scenarios, X'=8192, and in eDRX scenarios, X'=32768, based on this, it can be determined that in the eDRX scenario, the first parameter X is 8192*Y; in the eDRX scenario, the first parameter X is 32798*Y.

[0120] As a specific example, if the first group number is 8, then in a non-eDRX scenario, X=65536; in an eDRX scenario, X=262144.

[0121] By using the second terminal device identifier UE_ID which is different from the part of the UE_ID of the group ID determined by the grouping method based on the terminal device identifier of PEI, the terminal grouping corresponding to the LP-WUS of the terminal device can be different from the terminal grouping corresponding to the PEI, and the dependency between the terminal grouping corresponding to the LP-WUS and the terminal grouping corresponding to the PEI can be dispersed as much as possible, making the two groups independent of each other, thereby improving the diversity gain of reducing the false wake-up performance through different terminal groupings.

[0122] Mode 2: In the eDRX scenario, the first parameter X is the product of 1024 and the first group number; or, in the eDRX scenario, the first parameter X is the product of 4096 and the first group number.

[0123] Specifically, in order to make the above-mentioned second terminal device identifier UE_ID and part of the UE_ID of the group ID determined by PEI based on the grouping method of the terminal device identifier the same or partially overlap, the first parameter X can be defined as the product of 1024 and the first number of groups in a non-eDXR scenario, that is, 1024*Y; in an eDRX scenario, it can be defined as the product of 4096 and the first number of groups, that is, 4096*Y.

[0124] As a specific example, if the first group number is 8, then in a non-eDRX scenario, X = 8192; in an eDRX scenario, X = 32678. At this time, the second terminal device identifier UE_ID is completely identical to the part of UE_ID that the PEI determines the group ID based on the grouping method of the terminal device identifier.

[0125] By determining that part of the UE_ID of the group ID is identical or partially overlapped with the grouping method of the terminal device identifier based on the second terminal device identifier UE_ID and the PEI, the terminal group corresponding to the LP-WUS of the terminal device can be identical or partially identical to the terminal group corresponding to the PEI, thereby avoiding exposing more UE_ID information and possible security issues.

[0126] In some embodiments, the second parameter may include a second number of groups, which may be expressed as Np, for example. The second number of groups may be the maximum number of groups of the grouping method based on the terminal device identification corresponding to the PEI, or the number of groups of the grouping method based on the terminal device identification corresponding to the PEI, or the number of groups corresponding to the PEI, or the logarithm of the maximum number of groups of the grouping method based on the terminal device identification corresponding to the PEI, or the logarithm of the log2 of the number of groups of the grouping method based on the terminal device identification corresponding to the PEI, or the logarithm of the log2 of the number of groups corresponding to the PEI.

[0127] In some embodiments, the second parameter may include a second grouping number, which may be expressed as Np, for example. The second grouping number satisfies at least one of the following:

[0128] When the network is configured with PEI or PEI grouping, or the terminal device uses PEI, the second number of groups is the maximum number of groups based on the first grouping method corresponding to PEI, or the number of groups based on the first grouping method corresponding to PEI, or the number of groups corresponding to PEI, or the logarithm of the maximum number of groups based on the first grouping method corresponding to the paging advance indication PEI, or the logarithm of the log2 of the number of groups based on the first grouping method corresponding to PEI, or the logarithm of the log2 of the number of groups corresponding to PEI;

[0129] When the network is not configured with PEI or PEI grouping, or the terminal device does not support PEI or does not use PEI, the second grouping number is 1.

[0130] Optionally, since the grouping method based on terminal device identification corresponding to PEI is the same or similar to the grouping method based on terminal device identification corresponding to LP-WUS, the grouping method based on terminal device identification corresponding to PEI can also be called the first grouping method. Optionally, since the grouping method based on CN control corresponding to PEI is the same or similar to the grouping method based on CN control corresponding to LP-WUS, the grouping method based on CN control corresponding to PEI can also be called the second grouping method. In some implementable methods, the second grouping number Np in the second parameter can be the first grouping number itself, or the logarithm of the first grouping number with base 2 (i.e., log2(first grouping number)), and this application does not limit this. For example, when the second grouping number is 8, the first grouping number Np in the second parameter can take a value of 8, or 3. In some implementable embodiments, if the network is configured with PEI or PEI grouping, or if the terminal uses PEI, the second number of groups in the second parameter may be: the first number of groups itself, or the logarithm of the first number of groups with base 2 (i.e., log2(first number of groups)), for example, when the second number of groups is 8, the first number of groups Np in the second parameter may be 8, or 3. If the network is not configured with PEI or PEI grouping, or if the terminal does not support PEI or does not use PEI, the second number of groups in the second parameter may be 1.

[0131] Since PEI does not use the second grouping number when determining the group ID based on the grouping method of the terminal device identifier, the second parameter including the second grouping number can make the terminal grouping corresponding to the LP-WUS of the terminal device different from the terminal grouping corresponding to the PEI, and disperse the dependency between the terminal grouping corresponding to the LP-WUS and the terminal grouping corresponding to the PEI as much as possible, so that the two groups are independent of each other, thereby improving the diversity gain of reducing the false wake-up performance through different terminal groupings.

[0132] In some embodiments, the second parameter may be determined according to the following solution 1 or solution 2. Solution 1 and solution 2 both correspond to two solutions for determining the group ID of the terminal group to which the terminal device belongs when the target grouping mode includes the first grouping mode.

[0133] Solution 1: The second parameter may be determined according to the total number N of paging frames within a period T and the number Ns of POs in a PF. In this case, the second parameter may include N and Ns.

[0134] Exemplarily, the first terminal device identifier P in the above formula (1) and formula (2) can be expressed as the following formula (3):

[0135] P = floor(UE_ID / (N*Ns)) (3)

[0136] Among them, UE_ID represents the above-mentioned second terminal device identifier.

[0137] It should be noted that the formula (3) in the first solution can also be used to determine the grouping ID of the PEI based on the first grouping method.

[0138] Optionally, Solution 1 may be applicable to scenarios where a network-side device (such as an access network device) only provides configuration information corresponding to the first grouping mode of LP-WUS, or a terminal device only uses LP-WUS to control whether to monitor paging messages (i.e., does not use PEI to control whether to monitor paging messages).

[0139] Solution 2: Determine the second parameter according to the total number N of paging frames in a cycle, the number Ns of POs in a PF, and the second number Np of packets. In this case, the second parameter may include N, Ns, and Np.

[0140] Exemplarily, the first terminal device identifier P in the above formula (1) and formula (2) can be expressed as the following formula (4):

[0141] P=floor(UE_ID / (N*Ns*Np)) (3)

[0142] It should be noted that formula (4) is a solution for determining the group ID of LP-WUS based on the first grouping method provided in an embodiment of the present application, and is different from the solution for determining the group ID of PEI based on the first grouping method in the related art.

[0143] Optionally, Solution 2 may be applicable to a scenario in which a network-side device (such as an access network device) provides configuration information corresponding to the first grouping mode corresponding to LP-WUS and PEI respectively, or a terminal device uses LP-WUS and PEI to jointly control whether to monitor paging messages.

[0144] In the above-mentioned solution 1 and solution 2, the parameters N and Ns may be configured by the network side device. For example, the access network device may broadcast a system message including the parameters N and Ns.

[0145] It should also be noted that in both Solution 1 and Solution 2, the above-mentioned method 1 or method 2 can be used to obtain the first parameter X and determine the terminal group (group ID) to which the terminal device belongs.

[0146] When method 1 is used in scheme 1 to determine the first parameter, since the second terminal device identifier UE_ID is different from the part of UE_ID that determines the group ID based on the grouping method of the terminal device identifier by PEI, even if the same formula (3) as PEI is used to determine the terminal group to which the terminal device belongs, the obtained group ID corresponding to LP-WUS is different from the group ID corresponding to PEI, which can achieve the dependency relationship between the terminal group corresponding to LP-WUS and the terminal group corresponding to PEI, making the two groups independent of each other, thereby improving the diversity gain of reducing false wake-up performance through different terminal groupings.

[0147] When the first parameter is determined by using method 1 or method 2 in scheme 2, since the second parameter (such as N, Ns and Np) is different from the parameter (such as N and Ns) for determining the group ID based on the first grouping method of PEI, that is, a formula (4) different from PEI is used to determine the terminal group to which the terminal device belongs, regardless of whether the second terminal device identifier UE_ID is the same as the part of UE_ID for determining the group ID based on the grouping method of the terminal device identifier by PEI, the obtained group ID corresponding to LP-WUS must be different from the group ID corresponding to PEI, thereby being able to disperse the dependency between the terminal group corresponding to LP-WUS and the terminal group corresponding to PEI, making the two groups independent of each other, thereby being able to improve the diversity gain of reducing false wake-up performance through different terminal groupings.

[0148] When the group ID corresponding to LP-WUS is different from the group ID corresponding to PEI, the terminal device may also receive PEI from the network side device, wherein PEI includes indication information of the second target group ID of the second target terminal group that needs to receive the paging message.

[0149] Since the group ID corresponding to the LP-WUS is different from the group ID corresponding to the PEI, by further receiving the PEI after being determined to be awakened to determine whether to receive the paging message, a diversity gain can be obtained in reducing false awakenings of paging.

[0150] When method 2 is used in scheme 1 to determine the first parameter, since the second terminal device identifier UE_ID is identical to or partially overlaps with a portion of the UE_ID of the group ID determined by PEI based on the first grouping method, and the same formula (3) as that of PEI is used to determine the terminal group to which the terminal device belongs, the obtained group ID corresponding to the LP-WUS is identical to or partially overlaps with the group ID corresponding to the PEI, that is, the terminal group corresponding to the LP-WUS is identical to or partially identical to the terminal group corresponding to the PEI.

[0151] Optionally, when the terminal group corresponding to LP-WUS is identical or partially identical to the terminal group corresponding to PEI, the terminal device may also determine not to receive PEI. PEI includes indication information of a second target group ID for indicating a second target terminal group that needs to receive a paging message. Optionally, even if the network side device is configured with configuration information of a group for terminal device identification of PEI, the terminal device may determine not to receive PEI.

[0152] Since the group ID corresponding to LP-WUS is the same as the group ID corresponding to PEI, the group wake-up indication function of PEI can be realized by waking up according to the group ID indicated by LP-WUS. The terminal device does not need to detect PEI subsequently, which is beneficial to reducing the power consumption of the terminal device.

[0153] Optionally, when the terminal group corresponding to LP-WUS is identical or partially identical to the terminal group corresponding to PEI, the terminal device may also receive PEI from the network side device, wherein PEI includes indication information of the second target group ID for indicating the second target terminal group that needs to receive the paging message.

[0154] It should be noted that, when the target grouping mode includes the first grouping mode, if the network side device (such as the access network device) is only configured with the corresponding configuration information of LP-WUS, or the terminal device only uses LP-WUS to control whether to monitor the paging message (that is, does not use PEI to control whether to monitor the paging message), or the network side device is configured with the corresponding configuration information of LP-WUS and PEI, or the terminal device uses LP-WUS and PEI to jointly control whether to monitor the paging message, then the terminal device can adopt the corresponding grouping scheme in the above-mentioned scheme one or scheme two to determine the first grouping ID of the first terminal group where the terminal device is located.

[0155] In some embodiments, when the target grouping mode includes the second grouping mode, a message including the first grouping ID may be received from the core network device to determine the first grouping ID of the first terminal group in which the terminal device is located. Optionally, the message may include a non-access stratum (NAS) message.

[0156] Optionally, the terminal device may also send grouping capability information to the network side device, where the grouping capability information is used to indicate that the terminal device supports the second grouping mode, or indicates that the terminal device supports LP-WUS grouping, or indicates that the terminal device supports LP-WUS-based wake-up.

[0157] Exemplarily, the network side device includes at least one of an access network device and a core network device. Optionally, when the terminal device reports packet capability information to the access network device, the access network device may further report the packet capability information to the core network device. When the core network device determines that the terminal device supports the second packet mode, or supports LP-WUS packetization, or supports LP-WUS-based wake-up, it may send a message (such as a NAS message) to the terminal device to indicate the packet ID of the terminal device based on the second packet mode, that is, the above-mentioned first packet ID.

[0158] Optionally, when the terminal device receives the first packet ID from the core network device, the terminal device may also determine not to receive PEI, or receive PEI from the network side device, without limitation. When the terminal device determines not to receive PEI, the terminal device may monitor LP-WUS to determine whether to wake up; when the terminal device receives PEI, the terminal device may monitor LP-WUS and PEI to determine whether to wake up.

[0159] In some embodiments, the first group ID may be determined according to the group ID of the terminal group in which the terminal device corresponding to the PEI is located. Exemplarily, the first group ID is the same as the group ID of the terminal group corresponding to the PEI determined based on at least one of the first grouping mode and the second grouping mode.

[0160] As an implementable manner, when the target grouping method includes the first grouping method, the terminal device may use the terminal device identification group ID of the PEI (ie, the group ID corresponding to the first grouping method) as the first group ID.

[0161] Specifically, the group ID of the terminal group to which the terminal device belongs obtained by PEI based on the first grouping method in the related art can be used for the group ID of the terminal group to which the terminal device belongs corresponding to the first grouping method of LP-WUS.

[0162] In some embodiments, when the terminal does not support the use of PEI to control whether to monitor paging messages (and there is no corresponding configuration, such as the number of groups based on the terminal device identifier), the first group ID of the first terminal group to which the terminal device belongs can be determined according to the above-mentioned scheme one or scheme two.

[0163] Optionally, when the terminal device uses the terminal device identification group ID corresponding to PEI as the above-mentioned first group ID, the terminal device can also determine not to receive PEI. Optionally, even if the network side device is configured with configuration information corresponding to the first grouping method of PEI, the terminal device can determine not to receive PEI.

[0164] As another implementable manner, when the target grouping method includes the second grouping method, the first grouping ID may be determined according to the CN grouping ID corresponding to the PEI (ie, the grouping ID corresponding to the second grouping method).

[0165] Specifically, the group ID of the terminal group to which the terminal device belongs obtained by PEI based on the second grouping method in the related art can be used for the group ID of the terminal group to which the terminal device belongs corresponding to the second grouping method of LP-WUS.

[0166] In some embodiments, when the terminal does not support the use of PEI to control whether to monitor paging messages, but the core network device is configured with the CN group ID corresponding to the PEI, the terminal device can still determine the above-mentioned first group ID according to the CN group ID corresponding to the PEI.

[0167] Optionally, when the terminal device uses the group ID based on the second grouping method corresponding to PEI as the above-mentioned first group ID, the terminal device can also determine not to receive PEI. Optionally, even if the core network device is configured with the CN group ID corresponding to PEI, the terminal device can still determine not to receive PEI.

[0168] S220, the access network device determines a first group identification ID of a first terminal group to which the terminal device belongs.

[0169] Specifically, the access network device can determine the first group ID of the first terminal group in which each terminal device is located in the same manner as the terminal device. Here, each terminal device can be all terminal devices in the cell, or terminal devices to be awakened in the cell, or all terminal devices associated with a PO, or terminal devices to be awakened associated with a PO, and this application does not limit this.

[0170] Specifically, the process of determining the first group ID is similar to step 210, and reference may be made to the relevant description in step S210.

[0171] It should be noted that, for a terminal device, the way in which the access network device determines the group ID of the terminal group to which the terminal device belongs is the same as the way in which the terminal device itself determines the group ID of the terminal group to which it belongs. Accordingly, the group ID corresponding to the terminal device determined by the access network device is the same as the group ID of the terminal group to which the terminal device belongs determined by the terminal device itself.

[0172] For example, when the terminal device determines the first group ID according to the first grouping method, the access network device also determines the first group ID according to the first grouping method; when the terminal device determines the first group ID according to the second grouping method, the access network device also determines the first group ID according to the second grouping method; when the terminal device determines the first group ID according to the group ID of the terminal group to which the terminal device corresponding to the PEI is located, the access network device also determines the first group ID according to the group ID of the terminal group to which the terminal device corresponding to the PEI is located, thereby ensuring that the access network device and the terminal device correspond to the same terminal group.

[0173] S230, the access network device sends an LP-WUS, including first indication information, the first indication information is used to indicate the first target group ID of the first target terminal group that needs to be awakened, or the LP-WUS corresponds to the first target group ID of the first target terminal group that needs to be awakened, for example, the LPWUS can be a sequence, and the LP-WUS sequence corresponds to the first target group ID of the first target terminal group that needs to be awakened. Correspondingly, the terminal device receives the LP-WUS from the access network device.

[0174] Exemplarily, when the target grouping mode includes the first grouping mode, when the access network device wants to wake up a terminal device, the first indication information in the LP-WUS can indicate the group ID corresponding to the terminal device (i.e., the first target group ID) to wake up the terminal device. When the target grouping mode includes the second grouping mode, the access network device can receive the group ID of the terminal device to be awakened from the core network device, and the first indication information in the LP-WUS can indicate the group ID corresponding to the terminal device (i.e., the first target group ID) to wake up the terminal device. Accordingly, the terminal devices in the first target terminal group corresponding to the first target group ID must be awakened, and the terminal devices in the terminal groups corresponding to other terminal group IDs may not be awakened, so as to save power consumption of some terminal devices.

[0175] The first target terminal group may include one or more terminal groups, and the first target group ID may include one or more group IDs, which is not limited in the present application.

[0176] In some embodiments, the number of bits of the first indication information is determined according to the number of packets corresponding to the LP-WUS.

[0177] As an implementable method, the number of bits of the first indication information is the same as the number of groups corresponding to LP-WUS, so that each bit in the first indication information corresponds to a terminal group (or the group ID of the terminal group), which is used to indicate whether the terminal device in the corresponding terminal group is awakened.

[0178] For example, assuming that the group ID starts from 0, when the number of groups corresponding to LP-WUS or the maximum number of groups is 8, the first indication information may include 8 bits, wherein the first bit of the 8 bits is used to indicate whether the terminal device in the terminal group with group ID 0 is awakened, the second bit is used to indicate whether the terminal device in the terminal group with group ID 1 is awakened, and so on, the eighth bit is used to indicate whether the terminal device in the terminal group with group ID 7 is awakened.

[0179] As an example, a bit value of 1 in the first indication information may indicate that the terminal devices in the corresponding terminal group are awakened, and a bit value of 0 may indicate that the terminal devices in the corresponding terminal group are not awakened. Or conversely, a bit value of 0 may indicate that the terminal devices in the corresponding terminal group are awakened, and a bit value of 1 may indicate that the terminal devices in the corresponding terminal group are not awakened.

[0180] As another achievable manner, the number of bits of the first indication information is the logarithm of the number of groups corresponding to the LP-WUS with a base of 2. If the number of bits of the first indication information is M, and the number of groups corresponding to the LP-WUS is Y, then M=log2Y is satisfied. In this way, the first indication information can be used to indicate the group ID of the target terminal group to be awakened.

[0181] For example, assuming that the group ID starts from 0, when the number of groups corresponding to LP-WUS is 8, the first indication information may include 3 bits. When the first indication information is 000, it can be used to indicate that the terminal devices in the terminal group with group ID 0 are awakened (while the terminal devices in other terminal groups are not awakened). When the first indication information is 001, it can be used to indicate that the terminal devices in the terminal group with group ID 1 are awakened (while the terminal devices in other terminal groups are not awakened), and so on. When the first indication information is 111, it can be used to indicate that the terminal devices in the terminal group with group ID 7 are awakened (while the terminal devices in other terminal groups are not awakened), and so on.

[0182] Optionally, the number of bits M of the first indication information is a positive integer greater than or equal to 1, such as M=2, 4, 6, 8, 16, ..., etc., which is not limited in this application.

[0183] In some embodiments, the network side device may indicate the number of bits of the first indication information to the terminal device through at least one of the following messages: system information (SI), low power synchronization signal LP-SS, Preamble part of LP-WUS, radio resource control (RRC) release message, and NAS message.

[0184] Among them, when the number of bits of the first indication information is indicated to the terminal device through the Preamble part of SI, LP-SS, LP-WUS, and RRC release message, the network side device may be an access network device. When the number of bits of the first indication information is indicated to the terminal device through a NAS message, the network side device may be a core network device.

[0185] In some embodiments, the number of bits of the first indication information carried in the LP-WUS is predefined by the protocol, and this application does not limit this.

[0186] S240: The terminal device determines whether the terminal device is awakened according to the first group ID and the first indication information.

[0187] As an implementable manner, if the first target group ID includes the first group ID, it is determined that the terminal device is awakened.

[0188] Specifically, the first target group ID is the group ID of the first target terminal group that needs to be awakened. When the number of bits of the first indication information is the same as the number of groups corresponding to LP-WUS, the first target group ID is the group ID of the terminal group corresponding to the bit used to indicate the awakening of the terminal group in the first indication information, and the number of first target group IDs may be one or more. When the number of bits of the first indication information is the logarithm of the number of groups corresponding to LP-WUS with base 2, the first target group ID is the group ID of the awakening terminal group indicated by the first indication information, and the number of first target group IDs is one. When the first target group ID includes the first group ID of the first terminal group where the terminal device is located, it is determined that the terminal group where the terminal device is located is awakened, and the terminal device is awakened at this time. Optionally, a terminal device with the same group ID as the terminal device is also awakened.

[0189] On the contrary, if the first target group ID does not include the first group ID, it is determined that the terminal device is not awakened.

[0190] Specifically, when the first target group ID does not include the first group ID, the terminal group to which the terminal device belongs is not awakened, and at this time the terminal device is not awakened.

[0191] As another achievable manner, if the first target terminal group includes a terminal device, it is determined that the terminal device is awakened. Specifically, when the first target terminal group corresponding to the first target group ID indicated by the first indication information includes a terminal device, the first target group ID includes the first group ID of the terminal device, and at this time, it can be determined that the terminal device is awakened.

[0192] On the contrary, if the first target terminal group does not include the terminal device, it is determined that the terminal device is not awakened.

[0193] In some embodiments, determining whether the terminal device is awakened includes at least one of the following:

[0194] Determining whether the terminal device receives a paging message;

[0195] Determine whether the terminal device receives PEI;

[0196] Determine whether the terminal device has exited the low-power sleep mode;

[0197] Determine whether the terminal device monitors PDCCH;

[0198] determining whether the terminal device is transmitting or receiving signals through the primary receiver;

[0199] determining whether the terminal device receives system information;

[0200] Determine whether the terminal device performs random access.

[0201] That is, when the terminal device is awakened, the terminal device can perform at least one of receiving a paging message, receiving a PEI, exiting a low-power sleep mode, monitoring a PDCCH, sending and receiving signals through a main receiver, receiving a system message, and performing random access.

[0202] Optionally, the terminal device monitors the PDCCH, which means that the terminal device monitors the PDCCH through a main receiver. Exemplarily, the main receiver may be a main communication module, which is not limited.

[0203] Optionally, after being awakened, the terminal device may also receive PEI from a network side device (such as an access network device), and the PEI includes indication information of a second target group ID for indicating a second target terminal group that needs to receive a paging message. At this time, the terminal device may also determine the second group ID of the second terminal group in which it is located, and determine whether to receive the paging message based on its second group ID and the second target group ID.

[0204] If the terminal group corresponding to the LP-WUS of the terminal device is different from the terminal group corresponding to the PEI, then the second target terminal group is different from the first target terminal group, or the second target group ID is different from the first target group ID. Therefore, the embodiment of the present application can achieve the dependency relationship between the terminal group corresponding to the LP-WUS and the terminal group corresponding to the PEI, so that the two groups are independent of each other, thereby improving the diversity gain of reducing the false wake-up performance through different terminal groupings.

[0205] Therefore, the embodiment of the present application determines the group ID of the terminal group to which it belongs through the terminal device, and receives the LP-WUS from the access network device, and then determines whether to be awakened according to the group ID and the target group ID of the target terminal group that needs to be awakened indicated by the LP-WUS, thereby realizing awakening of multiple terminal device group indications to reduce the probability of terminal devices being awakened by mistake. Terminal devices outside the terminal group corresponding to the target group ID may not be awakened, thereby saving power consumption of some terminal devices.

[0206] In some embodiments, see Figure 7 , method 200 may further include step S250.

[0207] S250, the access network device sends second indication information to the terminal device, where the second indication information is used to indicate at least one of the first number of groups, the third number of groups, and the fourth number of groups. Correspondingly, the terminal device receives the second indication information.

[0208] The first number of groups includes the maximum number of groups based on the first grouping method corresponding to the LP-WUS, or the number of groups based on the first grouping method corresponding to the LP-WUS, or the logarithm of the maximum number of groups based on the first grouping method corresponding to the LP-WUS, or the logarithm of the log2 of the number of groups based on the first grouping method corresponding to the LP-WUS. Specifically, the first number of groups can refer to the relevant description above.

[0209] The third number of groups includes the maximum number of groups based on the second grouping method corresponding to the LP-WUS, or the number of groups based on the second grouping method corresponding to the LP-WUS, or the logarithm of the maximum number of groups based on the second grouping method corresponding to the LP-WUS, or the logarithm of the number of groups based on the second grouping method corresponding to the LP-WUS. The maximum number of groups based on the second grouping method corresponding to the LP-WUS and the number of groups based on the second grouping method corresponding to the LP-WUS may be equivalent descriptions.

[0210] The fourth number of groups includes the number of groups corresponding to the LP-WUS, or the number of bits corresponding to the first indication information in the LP-WUS, or the number of bits used to indicate the first target terminal group in the LP-WUS, or the logarithm of log2 of the number of groups corresponding to the LP-WUS, or a value corresponding to a base of 2 with the number of bits corresponding to the first indication information in the LP-WUS as an exponent, or a value corresponding to a base of 2 with the number of bits used to indicate the first target terminal group in the LP-WUS as an exponent.

[0211] Optionally, when each bit of the first indication information in the LP-WUS corresponds to a terminal group (or group ID), the number of bits of the first indication information is the same as the number of groups corresponding to the LP-WUS. Optionally, the bits used for the first target terminal group in the LP-WUS are the bits of the first indication information, so the number of bits used for the first target terminal group in the LP-WUS is equal to the number of bits of the first indication information.

[0212] In some embodiments, the second indication information may be carried in at least one of the following messages:

[0213] System information (SI), low power synchronization signal LP-SS, Preamble part of LP-WUS, and radio resource control (RRC) release message.

[0214] Optionally, the configuration information of the LP-WUS provided by the access network device to the terminal device may include the second indication information. Accordingly, the terminal device may determine the group ID of the terminal device according to the second indication information.

[0215] Optionally, method 200 may further include step S260.

[0216] S260: The terminal device determines the target grouping method according to the second indication information.

[0217] Specifically, the terminal device may determine the target grouping method according to at least one of the first grouping number, the third grouping number, and the fourth grouping number configured in the second indication information.

[0218] As an implementable manner, if the second indication information includes the third grouping number, the target grouping method includes the second grouping method.

[0219] That is, if the access network device is configured with the number of packets (or the maximum number of packets) based on the second grouping method corresponding to LP-WUS, the terminal device can determine that the packets corresponding to LP_WUS include packets based on the second grouping method (ie, CN packets).

[0220] As another possible implementation, if the second indication information includes the first grouping number, the target grouping method includes the first grouping method.

[0221] That is to say, if the access network device is configured with the number of packets (maximum number of packets) based on the first grouping method corresponding to LP-WUS, the terminal device can determine that the packets corresponding to LP_WUS include packets based on the first grouping method (ie, packets based on the terminal device identifier).

[0222] As another possible implementation, if the second indication information does not include the first grouping number or the first grouping number is 0, the target grouping method includes the second grouping method.

[0223] That is to say, if the access network device is not configured with the number of packets based on the first grouping method (maximum number of packets) corresponding to LP-WUS, or the number of packets based on the first grouping method (maximum number of packets) corresponding to the configured LP-WUS is 0, then the terminal device can determine that the packets corresponding to LP_WUS include packets based on the second grouping method (i.e., CN packets).

[0224] As another achievable manner, if the second indication information does not include the third grouping number or the third grouping number is 0, the target grouping method includes the first grouping method.

[0225] That is to say, if the access network device is not configured with the number of packets based on the second grouping method (maximum number of packets) corresponding to LP-WUS, or the configured number of packets based on the second grouping method (maximum number of packets) corresponding to LP-WUS is 0, the terminal device can determine that the packets corresponding to LP_WUS include packets based on the first grouping method (i.e., packets based on the terminal device identifier).

[0226] As another possible implementation, if the fourth grouping number in the second indication information is the same as the first grouping number, the target grouping method includes the first grouping method.

[0227] That is to say, if the number of packets corresponding to the LP-WUS configured by the access network device (maximum number of packets) is the same as the number of packets based on the first grouping method corresponding to the LP-WUS (maximum number of packets), the third number of packets is 0. At this time, the terminal device determines that the packets corresponding to the LP_WUS include packets based on the first grouping method (i.e., packets based on the terminal device identifier).

[0228] As another possible implementation, if the fourth grouping number in the second indication information is the same as the third grouping number, the target grouping method includes the second grouping method.

[0229] That is to say, if the number of packets corresponding to the LP-WUS configured by the access network device (maximum number of packets) is the same as the number of packets based on the second grouping method corresponding to the LP-WUS (maximum number of packets), the first number of packets is 0. At this time, the terminal device determines that the packets corresponding to the LP_WUS include packets based on the second grouping method (ie, CN packets).

[0230] As another possible implementation, if the fourth grouping number in the second indication information is greater than the third grouping number, the target grouping method includes the first grouping method and the second grouping method.

[0231] That is to say, if the number of packets corresponding to the LP-WUS configured by the access network device (the maximum number of packets) is greater than the number of packets based on the second grouping method corresponding to the LP-WUS (the maximum number of packets), the first number of packets is not 0. At this time, the terminal device determines that the packets corresponding to the LP_WUS include packets based on the first grouping method (i.e., packets based on the terminal device identifier) ​​and packets based on the second grouping method (i.e., CN packets).

[0232] As another possible implementation, if the fourth grouping number in the second indication information is greater than the first grouping number, the target grouping method includes the first grouping method and the second grouping method.

[0233] That is to say, if the number of packets corresponding to the LP-WUS configured by the access network device (the maximum number of packets) is greater than the number of packets based on the first grouping method corresponding to the LP-WUS (the maximum number of packets), the third number of packets is not 0. At this time, the terminal device determines that the packets corresponding to the LP_WUS include packets based on the first grouping method (i.e., packets based on the terminal device identifier) ​​and packets based on the second grouping method (i.e., CN packets).

[0234] In some other embodiments, the terminal device may also determine, based on the second indication information, whether the LP-WUS instructs the terminal device to wake up in a grouped manner (ie, whether the LP-WUS is grouped).

[0235] When it is determined that LP-WUS instructs the terminal device to wake up in a grouping manner, the terminal device executes the above step S210. When LP-WUS determines that it does not instruct the terminal device to wake up in a grouping manner, the terminal device may not execute the above step S210.

[0236] As an implementable manner, if the second indication information does not include the fourth group number or the fourth group number is 0, the LP-WUS does not use a grouping method to instruct the terminal device to wake up.

[0237] That is to say, if the access network device is not configured with the number of groups corresponding to LP-WUS (maximum number of groups), or the number of groups corresponding to LP-WUS (maximum number of groups) is 0, then the first number of groups and the third number of groups are both 0. At this time, multiple terminal devices are not grouped, so the terminal device determines that LP_WUS does not use a grouping method to instruct the terminal device to wake up.

[0238] As an implementable manner, if the second indication information does not include the first grouping number and does not include the third grouping number, or the first grouping number is 0 and the third grouping number is 0, LP-WUS does not use a grouping method to instruct the terminal device to wake up.

[0239] That is, if the first grouping number and the third grouping number configured by the access network device are both 0, multiple terminal devices are not grouped at this time, so the terminal device determines that LP_WUS does not use the grouping method to instruct the terminal device to wake up.

[0240] In some embodiments, see Figure 7 , method 200 may further include step S270.

[0241] S270, determining a target grouping method according to the grouping method corresponding to the PEI.

[0242] Exemplarily, the target grouping method may be the same as or partially the same as the grouping method corresponding to the PEI, or the target grouping method may be different from the grouping method corresponding to the PEI, which is not limited in the present application.

[0243] As an implementable manner, if the grouping method corresponding to the PEI includes the first grouping method, the target grouping method is the first grouping method.

[0244] Specifically, the grouping method corresponding to PEI includes a first grouping method, which may mean that the grouping method corresponding to PEI may be the first grouping method, or may mean that the grouping method corresponding to PEI is the first grouping method and the second grouping method. Exemplarily, when the grouping method corresponding to PEI is the first grouping method, the network side may provide the configuration information corresponding to the first grouping method of PEI; when the grouping method corresponding to PEI is the first grouping method and the second grouping method, the network side may provide the configuration information corresponding to the first grouping method of PEI and the configuration information based on the second grouping method. At this point, it means that the network side device supports the first grouping method, so the target grouping method corresponding to LP-WUS may be (i.e., use) the first grouping method.

[0245] As another implementable manner, if the grouping method corresponding to the PEI includes the second grouping method, the target grouping method is the second grouping method.

[0246] Specifically, the grouping method corresponding to PEI includes the second grouping method, which may mean that the grouping method corresponding to PEI may be the second grouping method, or that the grouping method corresponding to PEI is the first grouping method and the second grouping method. Exemplarily, when the grouping method corresponding to PEI is the second grouping method, the network side may provide the configuration information corresponding to the second grouping method of PEI; when the grouping method corresponding to PEI is the first grouping method and the second grouping method, the network side may provide the configuration information corresponding to the first grouping method of PEI and the configuration information based on the second grouping method. At this time, it means that the network side device supports the second grouping method, so the target grouping method corresponding to LP-WUS may be (i.e., use) the second grouping method.

[0247] As another implementable manner, if the grouping method corresponding to PEI is the first grouping method, the target grouping method is the first grouping method.

[0248] Specifically, when the grouping mode corresponding to PEI is the first grouping mode (i.e., the grouping mode corresponding to PEI only includes the first grouping mode), the network side can provide the configuration information corresponding to the first grouping mode of PEI. At this time, it means that the network side device supports the first grouping mode, so the target grouping mode corresponding to LP-WUS can be (i.e., use) the first grouping mode.

[0249] As another implementable manner, if the grouping method corresponding to PEI is the second grouping method, the target grouping method is the second grouping method.

[0250] Specifically, when the grouping mode corresponding to PEI is the second grouping mode (i.e., the grouping mode corresponding to PEI only includes the second grouping mode), the network side can provide the configuration information corresponding to the second grouping mode of PEI. At this time, it means that the network side device supports the second grouping mode, so the target grouping mode corresponding to LP-WUS can be (i.e., use) the second grouping mode.

[0251] As another implementable manner, if the grouping method corresponding to the PEI includes a first grouping method and a second grouping method, the target grouping method is the first grouping method and the second grouping method.

[0252] Specifically, when the grouping mode corresponding to PEI includes the first grouping mode and the second grouping mode, the network side can provide the configuration information corresponding to the first grouping mode and the configuration information based on the second grouping mode of PEI. At this time, it means that the network side device supports the first grouping mode and the second grouping mode, so the target grouping mode corresponding to LP-WUS can be (i.e., use) the first grouping mode and the second grouping mode.

[0253] As another achievable manner, if the grouping method corresponding to the PEI is the first grouping method, the target grouping method is the second grouping method.

[0254] As another implementable manner, if the grouping method corresponding to PEI is the second grouping method, the target grouping method is the first grouping method.

[0255] Specifically, by configuring the target grouping method to be different from the grouping method corresponding to PEI, it is beneficial to make the terminal grouping corresponding to LP-WUS different from the terminal grouping corresponding to PEI, thereby dispersing the dependency between the terminal grouping corresponding to LP-WUS and the terminal grouping corresponding to PEI as much as possible, making the two groups independent of each other, thereby improving the diversity gain of reducing false wake-up performance through different terminal groupings.

[0256] It should be noted that in method 200, one of steps S260 and S270 may be performed to determine the target grouping mode. The specific step to determine the target grouping mode may be configured by the network side or defined (or agreed) by the protocol, and this application does not limit this.

[0257] In some embodiments, the target grouping method adopted by LP-WUS may be defined (or agreed upon) by the protocol, and the embodiments of the present application do not limit this. For example, the protocol may agree to adopt a first grouping method to determine the group ID of the terminal device, or agree to adopt a second grouping method to determine the group ID of the terminal device, or agree to adopt a first grouping method and a second grouping method to determine the group ID of the terminal device, and the embodiments of the present application do not limit this.

[0258] In some embodiments, signaling interaction can be performed between nodes (such as between access network devices and core network devices) to notify LP-WUS of the corresponding grouping configuration. Through signaling interaction between nodes, the limited payload in LP-WUS can be better and more accurately utilized to achieve the respective grouping requirements between nodes, avoiding the problem of wasted groups causing insufficient groups or insufficient groups causing the terminal to be falsely awakened too high, thereby increasing power consumption.

[0259] Figure 8 A schematic diagram showing a signaling interaction process 300 between an access network device and a core network device is shown as follows Figure 8 As shown, the signaling interaction process 300 may include at least one of steps S310 and S320:

[0260] S310, the access network device sends a first notification message to the core network device,

[0261] Specifically, in step 310, the access network device can determine the fourth number of groups, that is, the number of groups corresponding to the LP-WUS, the number of bits corresponding to the first indication information in the LP-WUS message, or the number of bits in the LP-WUS used to indicate the first target terminal group, etc.

[0262] As an implementable manner, the first notification message may include the fourth grouping number. This implementation manner is applicable when the target grouping method only includes the second grouping method. When the target grouping method only includes the second grouping method, the terminal grouping only includes the CN grouping.

[0263] As another achievable method, the first notification message may include the third grouping number. This implementation method is applicable when the target grouping method only includes the second grouping method, or the target grouping method includes the first grouping method and the second grouping method. When the target grouping method includes the first grouping method and the second grouping method, the terminal grouping includes the terminal device identification group (or UE_ID grouping) and the CN grouping. Optionally, in this method, the core network device may not need to know the first grouping number.

[0264] As another achievable manner, the first notification message may include the first grouping number. This implementation manner is applicable to the target grouping mode including the first grouping mode and the second grouping mode.

[0265] Optionally, the core network device may learn the fourth number of groups in advance, for example, the core network device learns from the access network device, without limitation. When the core network device obtains the fourth number of groups and the first number of groups, the core network device may calculate the third number of groups according to the fourth number of groups and the first number of groups, that is, the number of groups (maximum number of groups) based on the second grouping method corresponding to the LP-WUS.

[0266] S320, the core network device sends a second notification message to the access network device.

[0267] Specifically, in step 320, the core network device can determine the fourth number of packets, that is, the number of packets corresponding to the LP-WUS, the number of bits corresponding to the first indication information in the LP-WUS message, or the number of bits in the LP-WUS used to indicate the first target terminal packet, etc.

[0268] As an implementable manner, the second notification message may include a fourth grouping number. This implementation manner is applicable when the target grouping method includes only the first grouping method, or the target grouping method includes the first grouping method and the second grouping method. When the target grouping method includes only the first grouping method, the terminal grouping includes only the terminal device identification group (UE_ID grouping).

[0269] Optionally, the access network device may learn the first number of groups in advance, for example, the access network device itself makes a decision without limitation.

[0270] As another achievable manner, the second notification message may include the third grouping number. This implementation manner is applicable when the target grouping mode includes only the second grouping mode, or the target grouping mode includes the first grouping mode and the second grouping mode.

[0271] Optionally, in the case where the target grouping includes the first grouping mode and the second grouping mode, the access network device may know the fourth grouping number in advance, for example, the access network device obtains it from the core network device, without limitation. When the access network device obtains the fourth grouping number and the third grouping number, the access core network device may calculate the first grouping number based on the fourth grouping number and the third grouping number, that is, the grouping number (maximum grouping number) corresponding to the LP-WUS based on the first grouping mode.

[0272] As another achievable manner, the first notification message may include the first grouping number. This implementation manner is applicable when the target grouping mode includes only the first grouping mode, or the target grouping mode includes the first grouping mode and the second grouping mode.

[0273] Optionally, the access network device may know the fourth grouping number in advance, for example, the access network device makes its own decision or obtains it from the core network device, without limitation. When the core network device obtains the fourth grouping number and the first grouping number, the core network device may calculate the third grouping number based on the fourth grouping number and the first grouping number, that is, the grouping number (maximum grouping number) corresponding to the LP-WUS based on the second grouping method.

[0274] The specific implementation modes of the present application are described in detail above in conjunction with the accompanying drawings. However, the present application is not limited to the specific details in the above implementation modes. Within the technical concept of the present application, the technical solution of the present application can be subjected to a variety of simple modifications, and these simple modifications all belong to the protection scope of the present application. For example, the various specific technical features described in the above specific implementation modes can be combined in any suitable manner without contradiction.

For another example, the various different implementation modes of the present application can also be arbitrarily combined, and as long as they do not violate the ideas of the present application, they should also be regarded as the contents disclosed in the present application.

[0275] It should also be understood that in the various method embodiments of the present application, the size of the sequence number of the above-mentioned processes does not mean the order of execution, and the execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.
