For example, the terminal device 110 is used to receive a paging message from the access network device 120.

[0048] 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 using wearable technology for 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 just hardware devices, but also achieve powerful functions through software support, data interaction, and cloud interaction. Broadly speaking, wearable smart devices include those that are fully functional, large in size, and can achieve complete or partial functions without relying on smartphones, such as smart watches or smart glasses, as well as those 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 smart bracelets and smart jewelry for vital sign monitoring.

[0049] 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 of human-machine interconnection and object-to-object interconnection.

[0050] 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 (OBUs).

[0051] In the embodiment of the present application, the access network device 120 is a device in a 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). For example, as an example and not a limitation, the access network device 120 may include: a gNB, a transmission reception point (TRP), an evolved Node B (eNB), a radio network controller (RNC), a Node B (NB), a base station controller (BSC), a base transceiver station (BTS), a home base station (e.g., a home evolved Node B, or a home Node B, HNB), a base band unit (BBU), or a wireless fidelity (Wifi) access point (AP).

[0052] In one network structure, the access network device 120 may include a centralized unit (CU) node, a distributed unit (DU) node, or a RAN device including a CU node and a DU node, or a RAN device including a control plane CU node (CU-CP node) and a user plane CU node (CU-UP node) and a DU node.

[0053] The access network device 120 provides services for the cell, and the terminal device 110 communicates with the access network device 120 through the transmission resources used by the cell (for example, frequency domain resources, or spectrum resources). The cell can be the cell corresponding to the access network device 120 (for example, a base station). The cell can 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, pico cells, 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.

[0054] The core network device 130 is configured to manage one or more access network devices 120. For example, the core network device 130 is configured to send information for the access network device to send a paging message to the access network device 120. For example, the core network device 130 may include at least one of a core network (CN) access and mobility management function (AMF), a user plane function (UPF) network element, a session management function (SMF) network element, a data network (DN), a unified data repository (UDR), or a unified data management (UDM).

[0055] It should be understood that Figure 1 exemplarily shows a core network device 130, an access network device 120 and a terminal device 110. In some embodiments, the communication system may include other numbers of core network devices, access network devices or terminal devices, and the embodiments of the present application are not limited to this.

[0056] It should be understood that in the embodiments of the present application, a device having a communication function in a network / system may be referred to as a communication device. Taking the communication system shown in Figure 1 as an example, the communication device may include a terminal device 110 having a communication function, an access network device 120, and a core network device 130, etc., which is not limited in the embodiments of the present application.

[0064] To facilitate a better understanding of the embodiments of the present application, the relevant content of the low power wake-up signal (Low Power-Wake up Signal, LP-WUS) in the existing NR system is introduced.

[0065] The 3rd Generation Partnership Project (3GPP) will begin research on introducing LP-WUS in mobile cellular systems in Rel-18. To reduce reception activity in terminal devices while in standby mode, effectively shutting down the radio frequency (RF) and baseband (modem) modules, significantly reducing power consumption during communication reception, this can be achieved by introducing a near-zero-power receiver within the terminal's receiving module. This near-zero-power receiver eliminates the complex signal detection (such as amplification, filtering, and quantization) required by the RF module and the signal processing required by the modem, relying solely on passive matched filtering and low-power signal processing. On the base station side, an on-demand wake-up signal is triggered, activating the near-zero-power receiver. This notification triggers a series of internal processes within the terminal device, such as turning on the RF transceiver and baseband processing modules.

[0066] The wake-up signal can be an LP-WUS, which is received by a low-power receiver (LP-WUR). As shown in Figure 2, the terminal device includes two modules. The first module is a main communication module for transmitting 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 transmitter to wake up the main communication module on the receiving end. Optionally, the second module can also receive a low-power beacon signal sent by the transmitter to provide time reference information and other information for receiving the low-power wake-up signal, and can also provide wake-up link management.

[0067] As shown in Figure 2, in energy-saving mode, the terminal device activates the second module to monitor the LP-WUS and deactivates the first module. Unless activated by the second module, the first module remains deactivated and does not send or receive data. When downlink data arrives, the second module detects the LP-WUS sent by the transmitter, which contains the terminal device's information. The second module then triggers the first module to switch from the deactivated state to the active state, allowing data to be sent and received. The second module can be activated continuously or discontinuously, and can receive LP-WUS signals while activated.

[0068] Figure 3 shows a schematic diagram of the basic format of an LP-WUS. As shown in Figure 3, an LP-WUS can include a preamble and data. The preamble field can be used for at least one of LP-WUS detection, synchronization, and data rate determination; the data field is used to carry data.

[0069] In some embodiments, LP-WUS can 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 identification processes such as possible sequence detection. Figure 4A shows a schematic diagram of an OOK signal.

[0070] As an implementation method, Orthogonal Frequency Division Multiplexing (OFDM) signal modulation can be used to generate OOK signals. For example, the transmission or non-transmission of the OFDM modulated sequence represents the on / off switching in the time domain. OOK signals can be received using receivers with lower power consumption, but such receivers have poor reception performance and coverage.

[0071] Optionally, information can be further carried using different sequences within the ON OFDM modulation sequence. For example, two sequences can represent information 0 and 1, respectively, or four signals can represent information 00, 10, 10, and 11, respectively. As shown in Figure 4B, part of the information is carried via OOK modulation (where the OOK bit is 1), while the other part of the information is carried via an ON-level OFDM sequence (where the OFDM bit is 4). Because demodulating the OFDM sequence requires a receiver capable of receiving OFDM signals, such receivers generally offer better demodulation performance than low-power receivers that can only demodulate OOK signals.

[0072] To facilitate a better understanding of the embodiments of the present application, the relevant content of the paging early indication (PEI) in the existing NR system is introduced.

[0073] 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 own associated paging opportunity (PO), and further receiving the paging physical downlink shared channel (PDSCH) after monitoring the paging PDCCH. Among them, multiple terminal devices are 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. The terminal device will not go to sleep until it confirms 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.

[0074] To reduce power consumption in terminal devices, the R17 standard further introduces PDCCH-based PEI. Before receiving a paging PDCCH, the terminal device first receives the PEI and determines whether it needs to monitor subsequent paging PDCCHs based on the content indicated in the PEI. If the 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 the PEI and the PO, thereby saving power.

[0075] 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, and 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 shown in Figure 5, where 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).

[0076] 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.

[0077] In a grouping method based on terminal device identification, the access network device can group multiple terminal devices. This grouping method can also be referred to as a grouping method controlled by the access network device. Optionally, the access network device can group based on 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 based on the identification of each terminal device. For example, the terminal device identification can be modulo-operated by the number of grouping groups. Each terminal device can also obtain its own group ID using 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.

[0078] In the CN-controlled grouping method, the core network device can group multiple terminal devices corresponding to a 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.

[0079] When a cell supports both the terminal device identification-based grouping method and the CN-controlled grouping method, the group ID obtained based on the CN-controlled grouping method (i.e., CN group ID) comes first, and the group ID obtained based on the terminal device identification-based grouping method (i.e., terminal device identification group ID) comes last. For example, a cell has a total of 6 terminal groups, the number of groupings based on the terminal device identification grouping method is 4, and the number of groupings based on the CN-controlled grouping method is 2. Then, the CN-based group IDs are 0 and 1, and the terminal device identification-based group IDs are 2, 3, 4, and 5. Therefore, for the terminal device identification group ID, the terminal device identification and the group number are modulo, and the group number based on the CN-controlled grouping method needs to be added. For example, if the terminal device identification and the group number are 0 after modulo, then the group number based on the CN-controlled grouping method, 2, is added to obtain the terminal device identification group ID of 2.

[0080] At present, in the related art, 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 remains 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 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 the terminal device needs to be solved urgently.

[0081] In order to solve the above technical problems, the embodiment of the present application uses LP-WUS to indicate the terminal group to which the terminal device to be awakened belongs, thereby realizing the awakening of multiple terminal device groups. 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 to be awakened. The terminal device determines whether to be awakened based on its group ID and the target group ID, thereby reducing 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.

[0082] The technical solution of this application is described in detail below through specific embodiments.

[0083] FIG6 shows a schematic flow chart of a communication method 200 according to an embodiment of the present application. As shown in FIG6 , the communication method 200 may include at least part of the following steps S210 to S240:

[0084] S210: The terminal device determines a first group ID of a first terminal group to which the terminal device belongs.

[0085] 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, so as to reduce the false wake-up rate of the terminal device and further reduce the power consumption of the terminal device.

[0086] 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.

[0087] In the first grouping mode, the access network device can group multiple terminal devices. The first grouping mode can also be referred to as a grouping mode controlled by the access network device (RAN). Optionally, the access network device can group based on the identifiers 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 based on the identifier of each terminal device. For example, the terminal device identifier can be modulo-operated by the number of grouping groups. Each terminal device can also obtain its own group ID using the same calculation method as the access network device. Optionally, the terminal device can support the first grouping mode by default.

[0088] Optionally, the group obtained based on the first grouping method can also be called a RAN group, a terminal device identification group, a UE_ID group, etc., which is not limited in this application.

[0089] In the second grouping mode, the core network device can group multiple terminal devices corresponding to a PO. The core network device can notify each terminal device of the group ID to which each terminal device belongs. Each terminal device can save the group ID assigned by the core network device. Optionally, the core network device can also notify the access network device of the group ID to which the terminal device belongs.

[0090] Optionally, the grouping obtained based on the second grouping method can also be called a CN grouping, which is not limited in this application.

[0091] Optionally, the target grouping method can include the following three situations:

[0092] Case 1: The target grouping method includes only the first grouping method but does not include the second grouping method.

[0093] Case 2: The target grouping method includes a first grouping method and a second grouping method.

[0094] Case 3: The target grouping method only includes the second grouping method but does not include the first grouping method.

[0095] 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.

[0096] Exemplarily, Case 1 and Case 2 are applicable to scenarios where the access network device supports the first grouping mode, or the access network device can provide the terminal device with 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.

[0097] Exemplarily, situation 3 is applicable to a scenario where 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.

[0098] 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 LP-WUS, or the number of groups based on the first grouping mode corresponding to LP-WUS, or the number of groups corresponding to LP-WUS, or the number of bits corresponding to the first indication information in LP-WUS.

[0099] 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.

[0100] 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. This application does not limit this.

[0101] Optionally, in the above case 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.

[0102] Optionally, in the above-mentioned case 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, and is used to indicate whether the terminal devices in the corresponding terminal group need to be awakened. Alternatively, each of the M bits of the first indication information corresponds to the group ID of a terminal group, and is used to indicate whether the terminal devices in the terminal group corresponding to the corresponding group ID need to be awakened. In this case, Y=M.

[0103] 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. 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.

[0104] 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 group ID can be determined according to the first terminal device identifier and the first group number of the terminal device.

[0105] For example, the first terminal device identifier P of the terminal device may be modulo the first group number Y to obtain the group ID corresponding to the terminal device, which may be specifically expressed as the following formula: Subgroup ID = P mod Y (1)

[0106] Here, SubgroupID represents the group ID.

[0107] 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 based on the first terminal device identifier of the terminal device, the first group number and the group ID starting value corresponding to the first grouping method.

[0108] For example, 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 may be determined as the group ID corresponding to the terminal device, which may be specifically expressed as the following formula: SubgroupID=P mod Y + S (2)

[0109] Optionally, the group ID starting value can be determined based on 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 arranged before the terminal device identification group ID corresponding to the LP-WUS.

[0110] For example, multiple terminal devices in a cell are divided into six terminal groups. The groups corresponding to the first grouping method (RAN groups, or terminal device identification groups) account for four groups, and the groups corresponding to the second grouping method (CN groups) account for two groups. Therefore, the CN group IDs can be 0 and 1, and the terminal device identification group IDs can be 2, 3, 4, and 5. In this case, the terminal device identification group ID is obtained by performing a modulo operation on the first group number and adding the CN group number (S = 2). This is the group ID based on the first grouping method.

[0111] 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).

[0112] 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).

[0113] In some embodiments, in method 200, the second terminal device identity of the terminal device may be determined based on the mobile user identity of the terminal device and the first parameter X; and the first terminal device identity may be determined based on the second terminal device identity and the second parameter.

[0114] Exemplarily, the mobile user identity may be a globally unique identifier assigned by the communication system to the terminal device, which may be used to uniquely identify the terminal device. As an example, the mobile user identity may be a 5G Global Unique Temporary UE Identity (5G-GUTI), or a 5G Temporary Mobile Subscription Identifier (TMSI), or a 5G-S-TMSI, etc., without limitation.

[0115] Specifically, the mobile user identity of the terminal device may be modulo-operated with 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 the LP-WUS to determine the group ID based on the first grouping method.

[0116] Optionally, the number of bits of the second terminal device identifier UE_ID is log2Y, where Y is the above-mentioned first group number.

[0117] 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.

[0118] In some embodiments, the first parameter X may be determined according to one of the following methods 1 and 2.

[0119] Mode 1: In a non-extended discontinuous reception (eDRX) scenario, the first parameter X is the product of 8192 and the first group number; or, in an eDRX scenario, the first parameter X is the product of 32798 and the first group number.

[0120] Specifically, under the grouping method based on the terminal equipment identifier (UE_ID) corresponding to PEI, the part of the UE_ID used for the PEI to determine the group ID based on the grouping method of the terminal equipment identifier can be determined according to the 5G-S-TMSI mod X'. In order to make the above-mentioned second terminal equipment identifier UE_ID different from the part of the UE_ID used for the PEI to determine the group ID based on the grouping method of the terminal equipment identifier, 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 the non-eDRX scenario, X'=8192, and in the eDRX scenario, 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.

[0121] 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.

[0122] By making the second terminal device identifier UE_ID 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 group corresponding to the LP-WUS of the terminal device can be different from the terminal group corresponding to the PEI, and the dependency relationship between the terminal group corresponding to the LP-WUS and the terminal group corresponding to the PEI can be dispersed 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.

[0123] 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.

[0124] 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 the non-eDXR scenario, that is, 1024*Y; in the eDRX scenario, it can be defined as the product of 4096 and the first number of groups, that is, 4096*Y.

[0125] 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. In this case, the second terminal device identifier UE_ID is identical to the portion of UE_ID used by the PEI to determine the group ID based on the terminal device identifier grouping method.

[0126] By determining that part of the UE_ID of the group ID is identical or partially overlapped with the grouping method of the second terminal device identifier UE_ID and the PEI based on the terminal device identifier, 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 avoiding possible security problems.

[0127] 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 in the grouping method based on the terminal device identifier corresponding to the PEI, or the number of groups in the grouping method based on the terminal device identifier corresponding to the PEI, or the number of groups corresponding to the PEI, or the logarithm of the maximum number of groups in the grouping method based on the terminal device identifier corresponding to the PEI, or the logarithm of the logarithm of the number of groups in the grouping method based on the terminal device identifier corresponding to the PEI, or the logarithm of the logarithm of the number of groups corresponding to the PEI.

[0128] In some embodiments, the second parameter may include a second group number, which may be expressed as Np, for example. The second group number satisfies at least one of the following:

[0129] 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 logarithm of the number of groups based on the first grouping method corresponding to PEI, or the logarithm of the logarithm of the number of groups corresponding to PEI;

[0130] 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.

[0131] 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 referred to as 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 referred to as 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 implementations, 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.

[0132] 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 includes the second grouping number, so that the terminal group corresponding to the LP-WUS of the terminal device is different from the terminal group corresponding to the PEI, and the dependency relationship between the terminal group corresponding to the LP-WUS and the terminal group corresponding to the PEI is dispersed 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.

[0133] 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.

[0134] 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.

[0135] For example, the first terminal device identifier P in the above formula (1) and formula (2) can be expressed as the following formula (3): 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 group ID of the PEI based on the first grouping method.

[0138] Optionally, Solution 1 may be applicable to scenarios where the network side device (such as access network device) only provides configuration information corresponding to the first grouping mode of LP-WUS, or the 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 based on the total number N of paging frames in a period, 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] For example, the first terminal device identifier P in the above formula (1) and formula (2) can be expressed as the following formula (4): P = floor (UE_ID / (N * Ns * Np)) (3)

[0141] 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.

[0142] Optionally, Solution 2 may be applicable to scenarios where network-side equipment (such as access network equipment) provides configuration information corresponding to the first grouping mode corresponding to LP-WUS and PEI respectively, or where the terminal equipment uses LP-WUS and PEI to jointly control whether to monitor paging messages.

[0143] In the above-mentioned solutions 1 and 2, the parameters N and Ns can be configured by the network-side device. For example, the access network device can broadcast a system message including the parameters N and Ns.

[0144] 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.

[0145] When method 1 is used to determine the first parameter in scheme 1, since the second terminal device identifier UE_ID is different from the part of the UE_ID used by PEI to determine the group ID based on the grouping method of the terminal device identifier, even if 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 different from the group ID corresponding to the PEI. This can achieve the goal of dispersing the dependency between the terminal group corresponding to the LP-WUS and the terminal group corresponding to the PEI, making the two groups independent of each other, thereby improving the diversity gain of reducing false wake-up performance through different terminal groupings.

[0146] 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 parameters (such as N and Ns) used by PEI to determine the group ID based on the first grouping method, that is, a formula (4) different from PEI is used to determine the terminal group to which the terminal device belongs. Therefore, regardless of whether the second terminal device identifier UE_ID is the same as the part of UE_ID used by PEI to determine the group ID based on the grouping method of the terminal device identifier, the obtained group ID corresponding to LP-WUS and the group ID corresponding to PEI must be different, thereby achieving the goal of dispersing 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 improving the diversity gain of reducing false wake-up performance through different terminal groupings.

[0147] When the group ID corresponding to LP-WUS is different from the group ID corresponding to PEI, the terminal device can also receive PEI from the network side device, where the PEI includes indication information of the second target group ID of the second target terminal group that needs to receive the paging message.

[0148] 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 caused by paging.

[0149] When method 2 is used to determine the first parameter in solution 1, since the second terminal device identifier UE_ID is identical to or partially overlaps with the portion of the UE_ID used by the PEI to determine the group ID based on the first grouping method, and the same formula (3) as that of the 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.

[0150] Optionally, if the terminal group corresponding to the LP-WUS is identical or partially identical to the terminal group corresponding to the PEI, the terminal device may also determine not to receive the PEI. The PEI includes indication information for a second target group ID of a second target terminal group that needs to receive a paging message. Optionally, even if the network-side device is configured with configuration information for the PEI group used to identify the terminal device, the terminal device may determine not to receive the PEI.

[0151] 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.

[0152] Optionally, when the terminal group corresponding to LP-WUS is identical or partially identical to the terminal group corresponding to PEI, the terminal device can also receive PEI from the network side device, wherein the PEI includes indication information of the second target group ID for indicating the second target terminal group that needs to receive the paging message.

[0153] 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 paging messages (that is, PEI is not used to control whether to monitor paging messages), 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 paging messages, then the terminal device can adopt the corresponding grouping scheme in the above-mentioned scheme one or scheme two to determine the first group ID of the first terminal group in which the terminal device is located.

[0154] In some embodiments, when the target grouping mode includes the second grouping mode, a message including a first group ID may be received from a core network device to determine the first group ID of a first terminal group in which the terminal device is located. Optionally, the message may include a non-access stratum (NAS) message.

[0155] 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.

[0156] 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.

[0157] Optionally, when the terminal device receives the first packet ID from the core network device, the terminal device may also determine not to receive the PEI, or receive the PEI from the network-side device, without limitation. When the terminal device determines not to receive the PEI, the terminal device may monitor the LP-WUS to determine whether to wake up; when the terminal device receives the PEI, the terminal device may monitor the LP-WUS and the PEI to determine whether to wake up.

[0158] In some embodiments, the first group ID may be determined based on the group ID of the terminal group that the terminal device corresponding to the PEI is in. 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 method and the second grouping method.

[0159] As an implementable manner, when the target grouping mode includes the first grouping mode, the terminal device may use the terminal device identification group ID of the PEI (ie, the group ID corresponding to the first grouping mode) as the first group ID.

[0160] 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 as the group ID of the terminal group to which the terminal device belongs corresponding to the first grouping method in LP-WUS.

[0161] 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 in which the terminal device is located can be determined according to the above-mentioned solution one or solution two.

[0162] Optionally, when the terminal device uses the terminal device identification group ID corresponding to the PEI as the above-mentioned first group ID, the terminal device can also determine not to receive the PEI. Optionally, even if the network side device is configured with configuration information corresponding to the first grouping method of the PEI, the terminal device can determine not to receive the PEI.

[0163] As another implementable manner, when the target grouping method includes the second grouping method, the first group ID may be determined according to the CN group ID corresponding to the PEI (ie, the group ID corresponding to the second grouping method).

[0164] 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 as the group ID of the terminal group to which the terminal device belongs corresponding to the second grouping method in LP-WUS.

[0165] In some embodiments, when the terminal does not support using PEI to control whether to monitor paging messages, but the core network device is configured with the CN group ID corresponding to PEI, the terminal device can still determine the above-mentioned first group ID based on the CN group ID corresponding to PEI.

[0166] Optionally, when the terminal device uses the group ID based on the second grouping method corresponding to the PEI as the above-mentioned first group ID, the terminal device can also determine not to receive the PEI. Optionally, even if the core network device is configured with the CN group ID corresponding to the PEI, the terminal device can still determine not to receive the PEI.

[0167] S220: The access network device determines a first group identifier ID of a first terminal group to which the terminal device belongs.

[0168] Specifically, the access network device may 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 may be all terminal devices in a cell, or terminal devices to be awakened in a 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.

[0169] 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 .

[0170] It should be noted that, for a terminal device, the way the access network device determines the group ID of the terminal group to which the terminal device belongs is the same as the way 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.

[0171] 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 where 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 where 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.

[0172] At step 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.

[0173] 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.

[0174] 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 this application.

[0175] 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.

[0176] 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.

[0177] 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, where 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.

[0178] 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.

[0179] As another possible implementation, the number of bits in the first indication information is the logarithm to the base 2 of the number of groups corresponding to the LP-WUS. Let M be the number of bits in the first indication information and Y be the number of groups corresponding to the LP-WUS, then M = log2Y. In this way, the first indication information can be used to indicate the group ID of the group of target terminals being awakened.

[0180] 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 device in the terminal group with group ID 0 is 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 device in the terminal group with group ID 1 is 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 device in the terminal group with group ID 7 is awakened (while the terminal devices in other terminal groups are not awakened), and so on.

[0181] 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.

[0182] 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.

[0183] When the number of bits of the first indication information is indicated to the terminal device through the Preamble part of the SI, LP-SS, LP-WUS, or 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.

[0184] 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.

[0185] S240: The terminal device determines whether the terminal device is awakened according to the first group ID and the first indication information.

[0186] As an implementable manner, if the first target group ID includes the first group ID, it is determined that the terminal device is awakened.

[0187] 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 can 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 at this time the terminal device is awakened. Optionally, a terminal device with the same group ID as the terminal device is also awakened.

[0188] 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.

[0189] Specifically, when the first target group ID does not include the first group ID, the terminal group to which the terminal device belongs has not been awakened, and the terminal device has not been awakened at this time.

[0190] As another achievable manner, if the first target terminal group includes a terminal device, then 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 then it can be determined that the terminal device is awakened.

[0191] 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.

[0192] In some embodiments, determining whether the terminal device is awake includes at least one of the following:

[0193] Determining whether the terminal device receives a paging message;

[0194] Determine whether the terminal device receives PEI;

[0195] Determine whether the terminal device has exited low-power sleep mode;

[0196] Determine whether the terminal device monitors PDCCH;

[0197] determining whether the terminal device is transmitting or receiving signals via the primary receiver;

[0198] determining whether the terminal device receives system information;

[0199] Determine whether the terminal device performs random access.

[0200] That is, when the terminal device is awakened, the terminal device can perform at least one of receiving paging messages, receiving PEI, exiting low-power sleep mode, monitoring PDCCH, sending and receiving signals through the main receiver, receiving system messages, and performing random access.

[0201] Optionally, the terminal device monitoring the PDCCH means that the terminal device monitors the PDCCH via a primary receiver. Exemplarily, the primary receiver may be a primary communication module, which is not limited.

[0202] Optionally, after being awakened, the terminal device may also receive a PEI from a network-side device (such as an access network device). The PEI includes indication information for a second target group ID of a second target terminal group that needs to receive the paging message. In this case, the terminal device may also determine the second group ID of the second terminal group and determine whether to receive the paging message based on the second group ID and the second target group ID.

[0203] 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.

[0204] Therefore, in the embodiments of the present application, a terminal device determines the group ID of the terminal group to which it belongs, receives the LP-WUS from the access network device, and then determines whether to be awakened based on the group ID and the target group ID of the target terminal group indicated by the LP-WUS. This allows the awakening of multiple terminal device groups, thereby reducing the probability of terminal devices being mistakenly awakened. Terminal devices outside the terminal group corresponding to the target group ID do not need to be awakened, thereby saving power consumption of some terminal devices.

[0205] In some embodiments, referring to FIG. 7 , method 200 may further include step S250 .

[0206] 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.

[0207] 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 logarithm of the number of groups based on the first grouping method corresponding to the LP-WUS. Specifically, the first number of groups can be found in the relevant description above.

[0208] 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 log2 logarithm of the maximum number of groups based on the second grouping method corresponding to the LP-WUS, or the log2 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.

[0209] 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 in the LP-WUS used to indicate the first target terminal group, or the logarithm of log2 of the number of groups corresponding to the LP-WUS, or the value corresponding to the number of bits corresponding to the first indication information in the LP-WUS with 2 as the base, or the value corresponding to the number of bits used to indicate the first target terminal group in the LP-WUS with 2 as the base.

[0210] 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 in the LP-WUS used for the first target terminal group are the bits of the first indication information, and therefore the number of bits in the LP-WUS used for the first target terminal group is equal to the number of bits of the first indication information.

[0211] In some embodiments, the second indication information may be carried in at least one of the following messages:

[0212] System information (SI), low power synchronization signal LP-SS, Preamble part of LP-WUS, and radio resource control (RRC) release message.

[0213] Optionally, the LP-WUS configuration information provided by the access network device to the terminal device may include second indication information. Accordingly, the terminal device may determine the group ID of the terminal device according to the second indication information.

[0214] Optionally, method 200 may further include step S260.

[0215] S260: The terminal device determines the target grouping method according to the second indication information.

[0216] Specifically, the terminal device may determine the target grouping mode 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.

[0217] As an implementable manner, if the second indication information includes the third grouping number, the target grouping method includes the second grouping method.

[0218] 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).

[0219] As another possible implementation manner, if the second indication information includes the first grouping number, the target grouping method includes the first grouping method.

[0220] That is to say, if the access network device is configured with the number of packets based on the first grouping method corresponding to LP-WUS (maximum number of packets), 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).

[0221] 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.

[0222] 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).

[0223] As another possible implementation 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.

[0224] 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, then 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).

[0225] 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.

[0226] That is to say, if the number of groups corresponding to the LP-WUS configured by the access network device (maximum number of groups) is the same as the number of groups based on the first grouping method corresponding to the LP-WUS (maximum number of groups), then the third number of groups is 0. At this time, the terminal device determines that the groups corresponding to the LP_WUS include groups based on the first grouping method (i.e., groups based on the terminal device identifier).

[0227] 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.

[0228] 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 (i.e., CN packets).

[0229] 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.

[0230] 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 greater than 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 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).

[0231] 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.

[0232] 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 greater than 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 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).

[0233] 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).

[0234] When it is determined that LP-WUS instructs the terminal device to wake up in a grouped 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 grouped manner, the terminal device may not execute the above step S210.

[0235] 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.

[0236] 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.

[0237] As an implementable manner, if the second indication information does not include the first group number and does not include the third group number, or the first group number is 0 and the third group number is 0, the LP-WUS does not use a grouping method to instruct the terminal device to wake up.

[0238] 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 a grouping method to instruct the terminal device to wake up.

[0239] In some embodiments, referring to FIG. 7 , method 200 may further include step S270 .

[0240] S270: Determine a target grouping method according to the grouping method corresponding to the PEI.

[0241] Illustratively, 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 this application.

[0242] 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.

[0243] Specifically, the grouping mode corresponding to PEI includes a first grouping mode, which may mean that the grouping mode corresponding to PEI may be the first grouping mode, or that the grouping mode corresponding to PEI is the first grouping mode and the second grouping mode. Exemplarily, when the grouping mode corresponding to PEI is the first grouping mode, the network side may provide the configuration information corresponding to the first grouping mode of PEI; when the grouping mode corresponding to PEI is the first grouping mode and the second grouping mode, the network side may provide the configuration information corresponding to the first grouping mode of PEI and the configuration information based on the second grouping mode. At this time, it means that the network side device supports the first grouping mode, so the target grouping mode corresponding to LP-WUS may be (i.e., use) the first grouping mode.

[0244] As another possible implementation, if the grouping method corresponding to the PEI includes the second grouping method, the target grouping method is the second grouping method.

[0245] Specifically, the grouping mode corresponding to PEI includes the second grouping mode, which may mean that the grouping mode corresponding to PEI may be the second grouping mode, or that the grouping mode corresponding to PEI is the first grouping mode and the second grouping mode. Exemplarily, when the grouping mode corresponding to PEI is the second grouping mode, the network side may provide the configuration information corresponding to the second grouping mode of PEI; when the grouping mode corresponding to PEI is the first grouping mode and the second grouping mode, the network side may provide the configuration information corresponding to the first grouping mode of PEI and the configuration information based on the second grouping mode. At this time, it means that the network side device supports the second grouping mode, so the target grouping mode corresponding to LP-WUS may be (i.e., use) the second grouping mode.

[0246] As another possible implementation, if the grouping method corresponding to the PEI is the first grouping method, the target grouping method is the first grouping method.

[0247] Specifically, when the grouping mode corresponding to the PEI is the first grouping mode (i.e., the grouping mode corresponding to the PEI only includes the first grouping mode), the network side can provide the configuration information corresponding to the PEI based on the first grouping mode. In this case, it indicates that the network side device supports the first grouping mode, and therefore the target grouping mode corresponding to the LP-WUS can be (i.e., use) the first grouping mode.

[0248] As another possible implementation, if the grouping method corresponding to the PEI is the second grouping method, the target grouping method is the second grouping method.

[0249] Specifically, when the grouping mode corresponding to the PEI is the second grouping mode (i.e., the grouping mode corresponding to the PEI only includes the second grouping mode), the network side can provide configuration information corresponding to the PEI based on the second grouping mode. In this case, it indicates that the network side device supports the second grouping mode, and therefore the target grouping mode corresponding to the LP-WUS can be (i.e., use) the second grouping mode.

[0250] As another possible implementation, if the grouping method corresponding to the PEI includes the first grouping method and the second grouping method, the target grouping method is the first grouping method and the second grouping method.

[0251] Specifically, when the grouping mode corresponding to the PEI includes a first grouping mode and a second grouping mode, the network side may provide configuration information corresponding to the PEI based on the first grouping mode and configuration information based on the second grouping mode. In this case, it indicates that the network side device supports the first grouping mode and the second grouping mode, and therefore the target grouping mode corresponding to the LP-WUS can be (i.e., use) the first grouping mode and the second grouping mode.

[0252] As another implementable manner, if the grouping method corresponding to the PEI is the first grouping method, the target grouping method is the second grouping method.

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

[0254] Specifically, by configuring the target grouping mode to be different from the grouping mode corresponding to PEI, it is possible 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.

[0255] It should be noted that in method 200, one of steps S260 and S270 may be executed to determine the target grouping mode. The specific step used 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.

[0256] In some embodiments, the target grouping method used by the LP-WUS may be defined (or agreed upon) by the protocol, and this embodiment of the present application does not limit this. For example, the protocol may agree to use a first grouping method to determine the group ID of a terminal device, or agree to use a second grouping method to determine the group ID of a terminal device, or agree to use both the first grouping method and the second grouping method to determine the group ID of a terminal device, and this embodiment of the present application does not limit this.

[0257] In some embodiments, signaling can be exchanged between nodes (e.g., between access network devices and core network devices) to notify the LP-WUS of the corresponding grouping configuration. This inter-node signaling interaction allows for better and more accurate utilization of the limited payload in the LP-WUS to meet the grouping requirements of each node, avoiding wasted packets resulting in insufficient grouping or insufficient grouping that increases the probability of false wakeups of terminals, leading to increased power consumption.

[0258] FIG8 shows a schematic diagram of a signaling interaction process 300 between an access network device and a core network device. As shown in FIG8 , the signaling interaction process 300 may include at least one of steps S310 and S320:

[0259] S310: The access network device sends a first notification message to the core network device.

[0260] 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.

[0261] As an implementation method, the first notification message may include the fourth grouping number. This implementation method 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.

[0262] 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 when 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.

[0263] 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 the first grouping mode and the second grouping mode.

[0264] Optionally, the core network device may obtain the fourth grouping number in advance, for example, from the access 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, i.e., the number of groups (maximum number of groups) corresponding to the LP-WUS based on the second grouping method.

[0265] S320: The core network device sends a second notification message to the access network device.

[0266] Specifically, in step 320, the core 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.

[0267] As an implementation method, the second notification message may include the fourth grouping number. This implementation method is applicable when the target grouping method includes only the first grouping method, or when 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 group).

[0268] Optionally, the access network device may know the first number of groups in advance, for example, the access network device may make its own decision, which is not limited.

[0269] 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 when the target grouping mode includes the first grouping mode and the second grouping mode.

[0270] Optionally, when the target grouping includes the first grouping mode and the second grouping mode, the access network device may obtain the fourth grouping number in advance, for example, by the access network device 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, i.e., the number of groups corresponding to the LP-WUS based on the first grouping mode (maximum number of groups).

[0271] 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 when the target grouping mode includes the first grouping mode and the second grouping mode.

[0272] Optionally, the access network device may learn the fourth grouping number in advance, for example, by the access network device itself or by learning 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, i.e., the number of groups (maximum number of groups) corresponding to the LP-WUS based on the second grouping method.

[0273] The specific embodiments 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 embodiments.

[0293] In some embodiments, the second parameter includes a second grouping number; wherein the second grouping number satisfies at least one of the following:

[0294] 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;

[0295] 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.

[0296] In some embodiments, the determining unit 11 is further configured to:

[0419] Figure 12 is a schematic diagram of the structure of a terminal device 40 provided in this application. This terminal device 40 can perform the actions performed by the terminal device in the above-described method embodiments. For ease of illustration, Figure 12 only illustrates the main components of the terminal device. As shown in Figure 12, the terminal device 40 includes a processor, memory, control circuitry, an antenna, and input / output devices.

[0420] The processor is primarily responsible for processing communication protocols and data, controlling the entire terminal device, executing software programs, and processing data from these programs. Memory is primarily used to store software programs and data. The control circuit is primarily responsible for converting baseband signals into radio frequency signals and processing these signals. The control circuit and antenna, together known as the transceiver, are primarily responsible for transmitting and receiving radio frequency signals in the form of electromagnetic waves. Input / output devices, such as touch screens, displays, and keyboards, are primarily responsible for receiving and outputting user input.

[0421] When the terminal device is powered on, the processor reads the software program stored in the storage unit, interprets and executes the program's instructions, and processes the program's data. When data needs to be transmitted wirelessly, the processor performs baseband processing on the data to be transmitted and outputs the baseband signal to the RF circuit. The RF circuit then performs RF processing on the baseband signal and transmits it via the antenna as electromagnetic waves. When data is sent to the terminal device, the RF circuit receives the RF signal via the antenna, converts it into a baseband signal, and outputs the baseband signal to the processor, which converts the baseband signal into data and processes it.

[0422] Those skilled in the art will appreciate that, for ease of explanation, FIG12 shows only one memory and processor. In an actual terminal device, multiple processors and memories may exist. The memory may also be referred to as a storage medium or storage device, etc., which is not limited in the present embodiment.

[0423] For example, a processor may include a baseband processor and a central processing unit (CPU). The baseband processor is primarily responsible for processing communication protocols and communication data, while the CPU is primarily responsible for controlling the entire terminal device, executing software programs, and processing data from software programs. The processor in Figure 12 integrates the functions of both the baseband processor and the CPU. Those skilled in the art will appreciate that the baseband processor and the CPU may also be independent processors interconnected via a bus or other technology. Those skilled in the art will appreciate that a terminal device may include multiple baseband processors to accommodate different network standards, multiple CPUs to enhance its processing capabilities, and that the various components of the terminal device may be connected via various buses. The baseband processor may also be referred to as a baseband processing circuit or a baseband processing chip. The CPU may also be referred to as a central processing circuit or a central processing chip. The functionality for processing communication protocols and communication data may be built into the processor or stored as a software program in a storage unit, with the processor executing the software program to implement the baseband processing functionality.

[0424] For example, in the embodiment of the present application, the antenna and control circuit with transceiver functions can be regarded as the transceiver unit 41 of the terminal device 40, and the processor with processing function can be regarded as the processing unit 42 of the terminal device 40. As shown in Figure 12, the terminal device 40 includes a transceiver unit 41 and a processing unit 42. The transceiver unit 41 can also be referred to as a transceiver, a transceiver, a transceiver device, etc. Optionally, the device used to implement the receiving function in the transceiver unit 41 can be regarded as a receiving unit, and the device used to implement the transmitting function in the transceiver unit 41 can be regarded as a transmitting unit, that is, the transceiver unit includes a receiving unit and a transmitting unit. For example, the receiving unit can also be referred to as a receiver, a receiver, a receiving circuit, etc., and the transmitting unit can be referred to as a transmitter, a transmitter, or a transmitting circuit, etc.

[0426] The BBU 52 is the control center of the base station, which can also be called a processing unit, and is mainly used to perform baseband processing functions such as channel coding, multiplexing, modulation, spread spectrum, etc. For example, the BBU (processing unit) 52 can be used to control the network device to execute the operation process of the network device in the above method embodiment.

[0427] In one example, the BBU52 can be composed of one or more single boards, and multiple single boards can jointly support a wireless access network with a single access standard (such as an LTE system or a 5G system), or can respectively support wireless access networks with different access standards. The BBU52 also includes a memory 521 and a processor 522. The memory 521 is used to store necessary instructions and data. The processor 522 is used to control the network device to perform necessary actions, such as controlling the network device to execute the operation process of the network device in the above method embodiment. The memory 521 and the processor 522 can serve one or more single boards. That is, a memory and a processor can be set separately on each single board. Alternatively, multiple single boards can share the same memory and processor. In addition, necessary circuits can also be set on each single board.

[0428] In one possible implementation, with the development of system-on-chip (SoC) technology, all or part of the functions of parts 52 and 51 can be implemented using SoC technology. For example, they can be implemented using a base station function chip that integrates a processor, memory, antenna interface, and other components. The programs for base station-related functions are stored in the memory, and the processor executes the programs to implement the base station-related functions. Optionally, the base station function chip can also read memory external to the chip to implement the base station-related functions.
