[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office of the People's Republic of China on February 2, 2024, with application number 202410149852.0 and invention name "A Communication Method and Device", the entire contents of which are incorporated by reference into this application. Technical Field

[0003] The present application relates to the field of mobile communication technologies, and in particular to a communication method and device. Background Art

[0004] With the development of technology, fifth-generation mobile communication technology (5G) is becoming increasingly popular. 5G networks (also known as new radio (NR)) support larger transmission bandwidths, more transmit and receive antenna arrays, higher transmission rates, and more flexible and fine-grained scheduling mechanisms. However, these also significantly increase the power consumption burden of user equipment (UE).

[0005] To reduce UE power consumption, the 3rd Generation Partnership Project (3GPP) introduced a power saving research topic in the NR Release 18 (Rel-18) standard. One method currently proposed is to apply low-power auxiliary function modules to 5G networks. Specifically, when monitoring a low-power wake-up signal (LP-WUS), only the auxiliary function module is turned on, leaving the main function module in deep sleep or shutdown. After the auxiliary function module receives the LP-WUS, it wakes up or turns on the corresponding main function module.

[0006] Currently, there are false alarms or missed detections in the auxiliary function module, and the wake-up accuracy needs to be improved. Summary of the Invention

[0007] The present application provides a communication method and apparatus for improving the wake-up accuracy of a receiver.

[0008] In a first aspect, a communication method is provided. The method can be implemented by a first communication device. The first communication device can be a terminal device (such as a first terminal). The first communication device can also be a component in the terminal device. Among them, the components in the present application may include, for example, at least one of a chip, a chip system, a processor, a transceiver, a processing unit, or a transceiver unit. It can be understood that the method is applied to the terminal device side. Taking the execution subject as the first communication device as an example, the communication method provided in the present application may include the following steps: the first communication device monitors first wake-up information and second wake-up information, the first wake-up information is used to indicate whether to wake up a terminal in a first terminal group, the first terminal group includes the first terminal, and the second wake-up information is used to indicate whether to wake up a terminal in a second terminal group, the second terminal group includes the first terminal; the first communication device determines whether to wake up the first terminal based on the first wake-up information and the second wake-up information.

[0009] Based on the first aspect, whether to wake up the first terminal can be determined based on the first wake-up information and the second wake-up information, wherein the first terminal belongs to the first terminal group and the second terminal group. Therefore, the terminal device can determine the wake-up status of the first terminal based on the wake-up information corresponding to at least two terminal groups (including the first wake-up information and the second wake-up information), and can determine the wake-up status more accurately to avoid false alarms or missed detections.

Alternatively, when at least one of the first wake-up information and the second wake-up information indicates not wake-up, it can be determined not to wake up the first terminal.

[0061] Figure 1 is a schematic diagram of the architecture of a communication system used in an embodiment of the present application. As shown in Figure 1 , the communication system includes a radio access network 100 and a core network 200. Optionally, the communication system may also include the Internet 300. The radio access network 100 may include at least one radio access network device (such as 110a and 110b in Figure 1 ) and at least one terminal (such as 120a-120j in Figure 1 ). The terminal is wirelessly connected to the radio access network device, and the radio access network device is wirelessly or wiredly connected to the core network. The core network device and the radio access network device may be independent, distinct physical devices, or the core network device's functions and the radio access network device's logical functions may be integrated into the same physical device, or a single physical device may integrate some of the core network device's functions and some of the radio access network device's functions. Terminals and radio access network devices may be interconnected via wired or wireless connections. Figure 1 is merely a schematic diagram. The communication system may also include other network devices, such as wireless relay devices and wireless backhaul devices, which are not shown in Figure 1 .

[0062] Radio access network equipment is the access device that allows terminals to wirelessly access a communication system. Radio access network equipment can include base stations, evolved NodeBs (eNodeBs), transmission reception points (TRPs), next-generation NodeBs (gNBs) in fifth-generation (5G) mobile communication systems, next-generation base stations in sixth-generation (6G) mobile communication systems, base stations in future mobile communication systems, Wi-Fi systems, long-range radio (LoRa) systems, or access nodes in connected vehicle systems. Radio access network equipment can also be modules or units that perform some of the functions of a base station, such as centralized units (CUs), distributed units (DUs), or radio units (RUs). The CU here completes the functions of the radio resource control protocol and the packet data convergence protocol (PDCP) of the base station, and can also complete the functions of the service data adaptation protocol (SDAP); the DU completes the functions of the radio link control layer and the medium access control (MAC) layer of the base station, and can also complete the functions of part of the physical layer or all of the physical layer; the RU can be included in the radio frequency device or the radio frequency unit. For the specific description of the above-mentioned various protocol layers, please refer to the relevant technical specifications of the 3rd Generation Partnership Project (3GPP). The wireless access network device can be a macro base station (such as 110a in Figure 1), a micro base station or an indoor station (such as 110b in Figure 1), or a relay node or a donor node. The embodiments of the present application do not limit the specific technology and specific device form adopted by the wireless access network device. For the convenience of description below, the network device is referred to as the abbreviation of the wireless access network device, and the base station is taken as an example of the wireless access network device.

[0063] A terminal is a device with wireless transceiver capabilities that can send signals to a base station or receive signals from a base station. A terminal may also be referred to as a terminal device, user equipment (UE), mobile station, mobile terminal, etc. Terminals can be widely used in various scenarios, such as device-to-device (D2D), vehicle-to-everything (V2X) communication, machine-type communication (MTC), Internet of Things (IoT), virtual reality, augmented reality, industrial control, autonomous driving, telemedicine, smart grid, smart furniture, smart office, smart wearable, smart transportation, smart city, etc. A terminal can be a mobile phone, tablet computer, computer with wireless transceiver capabilities, wearable device, vehicle, airplane, ship, robot, robotic arm, smart home device, etc. The embodiments of this application do not limit the specific technology and specific device form adopted by the terminal.

[0064] Base stations and terminals can be fixed or mobile. They can be deployed on land, indoors or outdoors, handheld or vehicle-mounted; on water; or on aircraft, balloons, and satellites. The embodiments of this application do not limit the application scenarios of base stations and terminals.

[0065] The roles of base stations and terminals can be relative. For example, the helicopter or drone 120i in Figure 1 can be configured as a mobile base station. To terminals 120j accessing the wireless access network 100 via 120i, terminal 120i is a base station. However, to base station 110a, 120i is a terminal, meaning that communication between 110a and 120i occurs via a wireless air interface protocol. Of course, communication between 110a and 120i can also occur via a base station-to-base station interface protocol. In this case, 120i is also a base station relative to 110a. Therefore, base stations and terminals can be collectively referred to as communication devices. 110a and 110b in Figure 1 can be referred to as communication devices with base station functionality, while 120a-120j in Figure 1 can be referred to as communication devices with terminal functionality.

[0066] Communication between base stations and terminals, between base stations, and between terminals can be carried out through authorized spectrum, unauthorized spectrum, or both; communication can be carried out through spectrum below 6 gigahertz (GHz), spectrum above 6 GHz, or spectrum below 6 GHz and spectrum above 6 GHz. The embodiments of the present application do not limit the spectrum resources used for wireless communication.

[0067] In the embodiments of the present application, the functions of the base station may also be performed by a module (such as a chip) in the base station, or by a control subsystem that includes the base station functions. The control subsystem that includes the base station functions here may be a control center in the above-mentioned application scenarios such as smart grid, industrial control, smart transportation, and smart city. The functions of the terminal may also be performed by a module (such as a chip or modem) in the terminal, or by a device that includes the terminal functions.

[0068] In this application, a base station sends downlink signals or downlink information to a terminal, and the downlink information is carried on a downlink channel; the terminal sends uplink signals or uplink information to the base station, and the uplink information is carried on an uplink channel. In order to communicate with the base station, the terminal needs to establish a wireless connection with the cell controlled by the base station. The cell with which the terminal has established a wireless connection is called the serving cell of the terminal. When the terminal communicates with the serving cell, it will also be subject to interference from signals in neighboring cells.

[0069] The following is an introduction to the technical terms that may be involved in this application.

[0070] (1) Main function module and auxiliary function module

[0071] In order to reduce the power consumption of the terminal, the terminal can use a working mode of a main function module and an auxiliary function module. The main function module and the auxiliary function module can be different links contained in the same module, or the main function module and the auxiliary function module can also be links contained in different modules. The main function module and the auxiliary function module can be communicatively connected.

[0072] The following describes the functions of the main function modules and auxiliary function modules in the terminal:

[0073] The main function module is used to implement various operations and functions of the terminal (such as radio resource management measurement and transmission of paging messages, etc.), and can also be called a main circuit module, main link, main circuit or main receiver. The main function module is, for example, the main radio circuit in the terminal. The main function module is used for the terminal to receive downlink signaling and data of the normal NR. Its power consumption in normal working state is relatively high, generally in the order of several milliwatts (mW). After the terminal enters the radio resource control (RRC) idle state or the RRC inactive state, the main function module enters the shutdown state (for example, power saving mode or extremely low power consumption state). At this time, the main function module does not perform radio resource management measurement, transmission of paging messages, cell reselection and cell switching, etc., which can effectively reduce the power consumption of the terminal due to the execution of the above operations.

[0074] The RRC idle state refers to the state in which a terminal is stationed in a cell but has not yet performed a random access procedure. The cell in which the terminal is stationed is called the stationed cell. A terminal typically enters the RRC idle state after powering on or after RRC release.

[0075] Taking the reception of a paging message as an example, when in RRC Idle or RRC Inactive state, a terminal calculates a paging frame (PF) and the location of a paging occasion (PO) within the PF based on its terminal identifier (UE ID), and receives the paging message within the PO of the paging frame. The same receiving module, i.e., the main functional module, can be used to perform the paging message reception process regardless of whether the terminal is in RRC Connected, RRC Idle, or RRC Inactive state.

[0076] The auxiliary function module can be used to receive low-power signals from the base station. Low-power signals can also be called WUS or LP-WUS, or WUR signals. The auxiliary function module can also be called a wake-up link, auxiliary link, auxiliary circuit, auxiliary receiver, or low-power receiver. The auxiliary function module is, for example, a wake-up receiver (WUR) circuit in the terminal. Compared with the main function module, the auxiliary function module consumes much less power.

[0077] The auxiliary function module may, for example, use some radio frequency circuits and baseband circuits with lower power consumption. For example, the auxiliary function module may not include a ring oscillator of a phase-locked loop, and use a low noise amplifier with a higher noise figure.

[0078] In another design, the auxiliary function module can be a submodule (i.e., a partial module) of the main function module, or it can reuse some circuits and devices with the main function module. Compared with the main function module, the auxiliary function module includes fewer components during operation. For example, the auxiliary function module does not include a fast Fourier transform module, a complex channel decoding module, a low-density parity check code (LDPC) decoding module, or a polarization decoding module. It may also have fewer registers and memory units and use a lower-bandwidth bus. Therefore, its power consumption is lower than that of the main function module.

[0079] In another design, the main function module can be an auxiliary function module in a low-power operating mode. For example, when the main function module reduces the operating voltage, slows down the clock frequency, or reduces the sampling rate and bit width of analog-to-digital sampling, it becomes an auxiliary function module. The specific implementation of the main function module and the auxiliary function module is not limited in the embodiments of the present application.

[0080] Hereinafter, the low power consumption signal LP-WUS is taken as an example for description.

[0081] The power consumption of the auxiliary function module in the working state is low, generally much lower than the power consumption of the main function module in the working state, generally in the microwatt (μW), hundred microwatts or even nanowatt (nW) level. For example, the power consumption of the auxiliary function module is less than 1 milliwatt. Based on the working modes of the above-mentioned main function module and auxiliary function module, when the terminal enters the RRC idle state or the RRC inactive state, the main function module can be set to enter an unconventional working state such as the off state, ultra-low power consumption state or ultra-deep sleep state, and the auxiliary function module can be used to monitor the LP-WUS of the base station. After monitoring the WUS, the main function module can be awakened through the connection with the main function module to put the main function module into the working state, that is, trigger the main function module to enter the working state (or exit the off state) from the off state to restore its function. Optionally, the WUS may be a signal using a modulation method such as orthogonal frequency division multiplexing (OFDM), on-off keying (OOK), amplitude-shift keying (ASK), or frequency-shift keying (FSK). Optionally, after the auxiliary function module wakes up the main function module, the auxiliary function module may switch from an active state to an inactive state, or the auxiliary function module may remain in an active state, which is not limited in the embodiments of the present application.

[0082] An exemplary LP-WUR workflow is as follows: First, the terminal turns on LP-WUR by default, and the main function modules remain off. LP-WUR monitors the low-power wake-up signal LP-WUS. LP-WUS triggers the wake-up of the main function modules. The main function modules are responsible for data transmission and reception and, unless turned on, can be turned off or set to very deep sleep. Monitoring LP-WUS power consumption depends on the LP-WUS design and the hardware modules of the wake-up receiver for signal detection and processing.

[0083] In this application, LP-WUR can be applied to power-sensitive devices and / or small devices, including IoT use cases (such as industrial sensors and controllers) and wearable devices. Furthermore, LP-WUR can be applied to other devices such as XR, smart glasses, and smartphones.

[0084] In order to further reduce the power consumption of the terminal in the RRC idle state, the terminal is awakened through an early wake-up indicator (PEI). In this application, awakening the terminal refers to waking up the main functional module of the terminal. The principle of PEI is that before receiving a paging message, the terminal first attempts to receive PEI, that is, PEI is an indication that precedes the transmission of a paging message. PEI can be used to indicate whether the terminal needs to receive a paging message in the next paging opportunity. PEI can be carried on LP-WUS.

[0085] Among them, PEI uses a grouping method to reduce the monitoring probability of paging occasions, further achieving the effect of energy saving. As an example, when the maximum number of paging subgroups is 8, PEI can include a bitmap, and can indicate whether the 8 paging subgroups are awakened through the bitmap, wherein any paging subgroup contains one or more terminals. For example, for a paging occasion, 8 paging subgroups can correspond to 8 bits, wherein any bit corresponds to 1 paging subgroup, and the bit value of any bit is 0, indicating that the paging subgroup corresponding to the bit is not awakened at the paging occasion, and the bit value of any bit is 1, indicating that the paging subgroup corresponding to the bit is not awakened at the paging occasion; or, the bit value of any bit is 1, indicating that the paging subgroup corresponding to the bit is not awakened at the paging occasion, and the bit value of any bit is 0, indicating that the paging subgroup corresponding to the bit is not awakened at the paging occasion. As shown in Figure 2, the paging occasions for UE#1, UE#2, UE#3, and UE#4 are all PO0. UE#1 and UE#2 belong to subgroup#0, while UE#3 and UE#4 belong to subgroup#1. The PEI uses a bitmap to indicate the wakeup status of all paging subgroups at any paging occasion, where each bit represents the wakeup status of a subgroup.

[0086] Taking PO0 as an example, if the bit value corresponding to subgroup#0 is 1, it means that all terminals belonging to subgroup#0 are awakened, that is, UE#0 and UE#1 are awakened at the position of PO0 and monitor paging messages at PO0; if the bit value corresponding to subgroup#1 is 0, it means that none of the terminals belonging to subgroup#1 are awakened, that is, UE#3 and UE#4 do not need to be awakened at the position of PO0.

[0087] In addition, the PEI can correspond to multiple paging occasions and / or paging frames. As shown in Figure 2, the PEI corresponds to paging frames PF0 and PF1, and paging frames PF0 and PF1 each contain two paging occasions (i.e., PO0 and PO1). When the maximum number of paging subgroups is 8, the PEI can contain up to 32 bits. Each PO corresponds to M bits in the PEI, and each bit corresponds to one paging subgroup. M is a positive integer, which is the number of paging subgroups corresponding to that bit.

[0088] For example, when M=8, the 8 bits correspond to paging subgroups subgroup #0 to subgroup #7. The terminal only needs to monitor the bit corresponding to the paging subgroup to which it belongs, and decide whether to wake up the main function module based on the bit, and then receive the paging message through the main function module.

[0089] It is understood that the number of paging subgroups can be preconfigured or predefined. In the present application, preconfiguration can refer to the configuration of the network device through signaling, and the relevant signaling can be, for example, RRC messages, MAC control information (control element, CE), downlink control information (downlink control information, DCI) or broadcast messages (such as system information block (SIB)), etc., without specific limitation. Predefinition can mean that the relevant information is defined through the local configuration or protocol of the communication device.

[0090] Currently, the wake-up mechanism of the main functional module is subject to false alarms or missed detections, and the wake-up accuracy needs to be improved. For example, the LP-WUR receives a bit indicating a "do not wake up" as a "do wake up" bit, which may cause the terminal to wake up incorrectly, increasing terminal power consumption. Alternatively, the LP-WUR receives a bit indicating a "do not wake up" as a "do not wake up" bit, which may cause missed detections and result in the terminal not receiving a paging message, requiring another paging request at a later paging opportunity, increasing transmission latency.

[0091] In order to improve the wake-up accuracy of a receiver, the present application provides a communication method.

[0092] It is understandable that the method is described below with the terminal and the network device as the execution subject, and the network device can also be replaced by an access network device, a base station or a network device in the network device as required. In addition, the terminal can be replaced by a UE, a terminal device, a terminal device, etc. The terminal and the network device can also be replaced by a chip or a chip system. When the method is implemented by a chip or a chip system, the receiving and sending steps therein can be understood as the chip or chip system communicating with other components in the device, for example, the communication between the baseband chip and the radio frequency circuit, etc. The processing performed by a single execution subject in the embodiment of the present application can also be divided into executions by multiple execution subjects, and these execution subjects can be logically and / or physically separated. For example, the processing performed by the network device can be divided into executions by at least one of the CU, DU and RU.

[0093] As shown in FIG3 , the communication method provided in the embodiment of the present application may include the following steps:

[0094] S101: A network device sends a first wake-up message and a second wake-up message. Correspondingly, a first terminal monitors the first wake-up message and the second wake-up message.

[0095] The first wake-up information indicates whether to wake up terminals in a first terminal group, where the terminals in the first terminal group include the first terminal. The second wake-up information indicates whether to wake up terminals in a second terminal group, where the terminals in the second terminal group include the first terminal. In other words, the first wake-up information and the second wake-up information each correspond to a terminal group, where the first terminal group corresponding to the first wake-up information and the second terminal group corresponding to the second wake-up information both include the first terminal.

[0096] In this application, monitoring can be understood as blind detection, detection or reception. In S101, the first terminal can monitor the first wake-up information and the second wake-up information through the auxiliary function module (such as LP-WUR).

[0097] The first terminal may determine the first wake-up information and the second wake-up information based on the identifier of the terminal group. In the present application, the identifier of the terminal group may be the group identifier of the terminal group. For example, if the terminal group is a paging subgroup, the group identifier of the terminal group may be a subgroup identifier (subgroup ID). The group identifier of the terminal group may be an integer greater than 0. For example, when the number of terminal groups is 8, the group identifiers of the terminal groups are numbers 0 to 7, respectively.

[0098] In this application, a terminal group can be a paging subgroup or a collection of terminals defined in a manner other than a paging subgroup, which is not specifically limited in this application. It can be understood that a terminal group can include one or more terminals. For example, the first terminal group can be understood as one or more terminals including the first terminal, and the first wake-up information can be understood as being used to wake up one or more terminals including the first terminal; similarly, the second terminal group can be understood as one or more terminals including the first terminal, and the second wake-up information can be understood as being used to wake up one or more terminals including the first terminal. This application does not exclude that both the first terminal group and the second terminal group include only the first terminal, in which case both the first wake-up information and the second wake-up information can be used to indicate whether to wake up the first terminal.

[0099] In one possible implementation, the first terminal group and the second terminal group may be the same terminal group, to which the first terminal belongs. In this case, the first wake-up message and the second wake-up message may be two repeatedly sent wake-up messages, each indicating the same content, i.e., both indicating that the terminal group to which the first terminal belongs should be woken up, or both indicating that the terminal group to which the first terminal belongs should not be woken up.

[0100] For example, the network device may repeatedly send the wake-up information of the first terminal (e.g., including the first wake-up information and the second wake-up information) within one LP-WUS period, so that the first terminal determines whether to wake up based on the repeatedly sent wake-up information, thereby reducing the risk of wake-up errors. In addition, the network device may repeatedly send the wake-up information of the first terminal (e.g., including the first wake-up information and the second wake-up information) through different beams, thereby repeatedly sending the wake-up information of the first terminal in multiple areas, antenna directions, or spatial directions through different beams.

[0101] In another possible implementation, the first terminal group and the second terminal group may be different terminal groups. For example, at least one terminal in the first terminal group does not belong to the second terminal group, and / or at least one terminal in the second terminal group does not belong to the first terminal group.

[0102] It is understood that in S101, the first terminal needs to monitor the first wake-up information and the second wake-up information, and the first terminal can receive at least one of the first wake-up information and the second wake-up information through monitoring. For example, after monitoring the first wake-up information and the second wake-up information, one or more of the first wake-up information and the second wake-up information may not be successfully received due to reasons such as a poor channel.

[0103] S102: The first terminal determines whether to wake up the first terminal according to the first wake-up information and the second wake-up information.

[0104] In S102, the first terminal may determine whether to wake up the main function module, such as waking up the main receiver, based on the first wake-up information and the second wake-up information, so that the terminal can receive information or messages such as paging messages through the main receiver.

[0105] Based on the insertion process shown in Figure 3, it can be determined whether to wake up the first terminal based on the first wake-up information and the second wake-up information, wherein the first terminal belongs to the first terminal group and the second terminal group. Therefore, the terminal can determine the wake-up status of the first terminal based on the wake-up information corresponding to at least two terminal groups, and can determine the wake-up status more accurately to avoid false alarms or missed detections.

[0106] In this application, the first terminal can determine the terminal group to which the first terminal belongs based on the group identifier. The terminal group to which the first terminal belongs may include the first terminal group and the second terminal group, that is, this application does not limit the first terminal to include other terminal groups in addition to the first terminal group and the second terminal group.

[0107] The following describes how the first terminal determines the terminal group identifier.

[0108] In one method of determining a group identifier, a first terminal may receive information from a network device, where the information may be used to indicate the group identifier of the terminal group to which the first terminal belongs. In this case, the identifier of the terminal group to which the first terminal belongs may be configured by the network device. The terminal group to which the first terminal belongs may include a first terminal group and / or a second terminal group. The network device may be an access network device (such as a base station) and / or a core network device (such as an access and mobility management function (AMF)), without specific limitation.

[0109] As an example, the information indicating the group identifier of the terminal group to which the first terminal belongs may include the group identifier of the first terminal group and the group identifier of the second terminal group. Therefore, the first terminal can obtain the group identifier of the first terminal group and the group identifier of the second terminal group from the configuration. In this case, this information can be referred to as first information. Alternatively, the first information may include, carry, or indicate the group identifier of the first terminal group and the group identifier of the second terminal group.

[0110] The group identifier of the first terminal group and the group identifier of the second terminal group may come from a core network device (such as an AMF) and an access network device, respectively. For example, the group identifier of the first terminal group of the first terminal is allocated by the AMF, and the group identifier of the second terminal group of the first terminal is allocated by the base station.

[0111] As another example, the information indicating the group identifier of the terminal group to which the first terminal belongs may include one of the group identifier of the first terminal group and the group identifier of the second terminal group. In this case, this information may be referred to as second information. Alternatively, the second information may include, carry, or indicate one of the group identifier of the first terminal group and the group identifier of the second terminal group.

[0112] For example, if the second information includes the group identifier of the first terminal group, the first terminal can determine the group identifier of the second terminal group based on the group identifier of the first terminal group. For example, the group identifier of the first terminal group and the group identifier of the second terminal group are associated with each other. This association may be, for example, that the group identifier of the first terminal group and the group identifier of the second terminal group are consecutive integers, or that the group identifier of the first terminal group and the group identifier of the second terminal group are integers with a specific value greater than 1 between them.

[0113] Optionally, the information used to indicate the group identifier of the terminal group to which the first terminal belongs may come from a core network device or an access network device. For example, the second information may be carried in a non-access stratum (NAS) message sent by the AMF to the first terminal via the base station.

[0114] In another manner of determining the group identifier, the first terminal may determine the identifier of the terminal group to which the first terminal belongs based on the number of terminal groups to which the first terminal belongs. That is, the first terminal may determine the identifier of the first terminal group and / or the identifier of the second terminal group based on the number of terminal groups to which the first terminal belongs.

[0115] The number of terminal groups to which the first terminal belongs may be configured by the network device, or the number of terminal groups to which the first terminal belongs may be a predefined number, such as 2.

[0116] If the number of terminal groups to which the first terminal belongs is configured by a network device, the terminal may receive third information, which may include, carry, or be used to indicate the number of terminal groups to which the first terminal belongs. The third information may come from a core network element or an access network device. The third information may be carried in the LP-WUS. For example, the LP-WUS header may include a field that may be used to carry the third information indicating the number of terminal groups to which the first terminal belongs. For example, the field may carry a numerical value of the number, or an index corresponding to the number, which may correspond to the number or be used to calculate the number.

[0117] As an example, the identifier of the terminal group to which the first terminal belongs can be determined based on the number of terminal groups to which the first terminal belongs, and based on at least one of the following: the identifier of the first terminal, the number of all paging frames within T, where T is the cycle length of discontinuous reception (DRX) used in the RRC idle state, the number of paging opportunities within a paging frame, the number of terminal groups included in a paging opportunity, and the total number of terminal groups. Among them, the use of DRX in the RRC idle state can be referred to as iDRX, which refers to the length of a DRX in the RRC idle state.

[0118] Taking the terminal group as a paging subgroup as an example, the identifier SubgroupID of the terminal group to which the first terminal belongs may satisfy:

[0119] SubgroupID=(floor(UE_ID / (N*Ns))mod subgroupsNumForUEID)+(subgroupsNumPerPO-subgroupsNumForUEID)+{0,k*x} (Formula 1);

[0120] In Formula 1, UE_ID can be determined based on the identifier of the first terminal. Here, the identifier of the first terminal can be a temporary mobile subscription identifier (TMSI) of the first terminal, such as a 5G S-TMSI. For example, UE_ID can satisfy: UE_ID = 5G-S-TMSI mod X. If the first terminal supports extended discontinuous reception (eDRX), X is equal to 32768, otherwise, X is equal to 8192. mod represents a modulo operation.

[0121] In addition, in Formula 1, floor means rounding down, and * means multiplication. N represents the number of all paging frames within T. Ns represents the number of paging occasions within a paging frame. subgroupsNumForUEID represents the number of paging occasions within a paging frame. subgroupsNumPerPO represents the total number of terminal groups, which includes the number of terminal groups configured by the network and the number of terminal groups determined by the terminal based on the number of terminal groups to which the terminal belongs. Among them, subgroupsNumPerPO can be indicated by SIB. k represents the interval between the group identifiers of multiple terminal groups of the same terminal, for example, the interval is a positive integer. x is the number of terminal groups to which the first terminal belongs.

[0122] Based on Formula 1, taking k=1 and x=2 as an example, the group identifier of the first terminal group of the first terminal is expressed as: (floor(UE_ID / (N*Ns))mod subgroupsNumForUEID)+(subgroupsNumPerPO-subgroupsNumForUEID). The group identifier of the second terminal group of the first terminal is expressed as: (floor(UE_ID / (N*Ns))mod subgroupsNumForUEID)+(subgroupsNumPerPO-subgroupsNumForUEID)+1. In other words, at this time, the difference between the group identifier of the first terminal group of the first terminal and the group identifier of the second terminal group is 1.

[0123] It can be understood that if the terminal group to which the first terminal belongs also includes other terminal groups besides the first terminal group and the second terminal group, the method for determining the group identifier of the other terminal groups can refer to the method for determining the group identifier of the first terminal group or the second terminal group, and no further details will be given.

[0124] The following describes how the first wake-up information indicates whether to wake up the terminals in the first terminal group.

[0125] Taking the first wake-up information as an example, the first wake-up information in this application may include a bit in a bitmap, which may be used to indicate whether to wake up a terminal in the first terminal group. The bit may be a bit corresponding to the first terminal group.

[0126] For example, the first wake-up information may include 1 bit, and when its value is 0, it may indicate that the terminals in the first terminal group are not woken up, and when its value is 1, it may indicate that the terminals in the first terminal group are woken up; or, when the value of this bit is 1, it may indicate that the terminals in the first terminal group are not woken up, and when its value is 0, it may indicate that the terminals in the first terminal group are woken up.

[0127] In addition, the first wake-up information may include, carry or indicate an identifier of a terminal group to be awakened or not awakened, or the first wake-up information may include, carry or indicate an identifier of a terminal in the terminal group to be awakened or not awakened.

[0128] For example, the first wake-up information can be used to indicate the identifier of the terminal group that needs to be awakened. If the first wake-up information indicates the identifier of the first terminal group, it means that the terminals in the first terminal group are awakened; or, the first wake-up information can be used to indicate the identifier of the terminal group that does not need to be awakened. If the first wake-up information indicates the identifier of the first terminal group, it means that the terminals in the first terminal group are not awakened.

[0129] Similarly, the second wake-up information is applicable to the above description of the first wake-up information and will not be repeated here.

[0130] In one possible implementation of S101, the first wake-up information and the second wake-up information may be carried in a wake-up signal, such as an LP-WUS. The first wake-up information and the second wake-up information may be carried in the same LP-WUS or in different LP-WUSs. If the first wake-up information and the second wake-up information are carried in different LP-WUSs, the different LP-WUSs may belong to the same wake-up cycle. This can avoid a long interval between the first wake-up information and the second wake-up information, which could lead to poor transmission performance. Furthermore, the delay in receiving a paging message after receiving all LP-WUSs can be reduced.

[0131] In a possible embodiment, when the first wake-up information and the second wake-up information can be carried in the same LP-WUS, the first wake-up information and the second wake-up information can be two different bits in the same bitmap, respectively, and the bitmap is carried in the LP-WUS, or in other words, the bitmap corresponds to the LP-WUS. For example, one LP-WUS can carry N bits, and the N bits can be used as a bitmap. The first wake-up information and the second wake-up information can be one bit in the N bits, respectively. Any bit in the N bits can correspond to a terminal group in N terminal groups (such as including a first terminal group and a second terminal group), and any bit is used to indicate whether to wake up a terminal in the corresponding terminal group, and the N terminal groups include the first terminal group and the second terminal group, and N is a positive integer greater than 1.

[0132] For example, as shown in Figure 4, paging occasion MO#0 is associated with UE#1 to UE#6, where the first terminal is UE#2. It can be seen that UE#2 belongs to two paging subgroups - subgroup#0 and subgroup#1, or in other words, the identifiers of the paging subgroups to which UE#2 belongs are 0 and 1. Among them, subgroup#0 and subgroup#1 are associated with the same LP-WUS, or in other words, the wake-up information corresponding to subgroup#0 and the wake-up information corresponding to subgroup#1 are carried on the same LP-WUS. In Figure 4, the first wake-up information and the second wake-up information are respectively one bit in the bitmap corresponding to the LP-WUS. Specifically, the first wake-up information is the bit corresponding to subgroup#0 in the bitmap, and the second wake-up information is the bit corresponding to subgroup#1 in the bitmap. It can also be said that the first wake-up information and the second wake-up information of UE#2 are associated with one LP-WUS, or in other words, the first wake-up information and the second wake-up information of UE#2 are associated with the same paging occasion.

[0133] In a possible embodiment, when the first wake-up information and the second wake-up information can be carried in two different LP-WUSs, the first wake-up information and the second wake-up information can be bits in two bitmaps respectively.

[0134] For example, as shown in Figure 5, paging occasion MO#0 is associated with UE#1 to UE#6, and paging occasion MO#1 is associated with UE#2, UE#7 to UE#12. MO#0 and MO#1 are respectively associated with different LP-WUSs, for example, MO#0 and MO#1 are respectively associated with two adjacent LP-WUSs. Among them, the first terminal is UE#2. It can be seen that UE#2 belongs to two paging subgroups - subgroup#0 corresponding to MO#0 and subgroup#0 corresponding to MO#1, or in other words, for MO#0 and MO#1, the identifier of the paging subgroup to which UE#2 belongs is 0. Among them, the first wake-up information and the second wake-up information correspond to different MOs. In Figure 5, the first wake-up information is 1 bit in the bit map corresponding to MO#0, and the second wake-up information is 1 bit in the bit map corresponding to MO#1. Specifically, the first wake-up information is the bit corresponding to subgroup#0 in the bit map corresponding to MO#0, and the second wake-up information is the bit corresponding to subgroup#0 in the bit map corresponding to MO#1. For the example shown in FIG5 , the first wake-up information and the second wake-up information of UE#2 are associated with different LP-WUSs, or in other words, the first wake-up information and the second wake-up information of UE#2 are associated with different paging occasions.

[0135] In a possible embodiment, when the first wake-up information and the second wake-up information can be carried on two different LP-WUSs, the first wake-up information can be used to indicate the identifier of the first terminal group. For example, the first wake-up information can carry the identifier of the first terminal group to indicate whether to wake up the first terminal group or not. For another example, the first wake-up information can carry the identifier of the terminal in the first terminal group to indicate whether to wake up the terminals in the first terminal group or not. In addition, the second wake-up information can be used to indicate the identifier of the second terminal group. For example, the second wake-up information can carry the identifier of the second terminal group to indicate whether to wake up the second terminal group or not. For another example, the second wake-up information can carry the identifier of the terminal in the second terminal group to indicate whether to wake up the terminals in the second terminal group or not.

[0136] For example, as shown in Figure 6, paging occasion MO#0 is associated with UE#1 to UE#6, and paging occasion MO#1 is associated with UE#2, UE#7 to UE#12. MO#0 and MO#1 are respectively associated with different LP-WUS, for example, MO#0 and MO#1 are respectively associated with two adjacent LP-WUS. Among them, the first terminal is UE#2. It can be seen that UE#2 belongs to two paging subgroups - subgroup#0 corresponding to MO#0 and subgroup#0 corresponding to MO#1, or in other words, for MO#0 and MO#1, the identifier of the paging subgroup to which UE#2 belongs is 0. In Figure 6, the first wake-up information is used to indicate the awakened or non-awakened paging subgroup in the paging subgroup corresponding to MO#0, and the second wake-up information is used to indicate the awakened or non-awakened paging subgroup in the paging subgroup corresponding to MO#1. Among them, the first wake-up information and the second wake-up information correspond to different MOs.

[0137] The following description will be made using the first wake-up information as an example, and the second wake-up information can be implemented accordingly. When the paging subgroup indicated by the wake-up information is the paging subgroup to be awakened, if the paging subgroup to be awakened in the paging subgroup corresponding to MO#0 is subgroup#0, then the first wake-up information can be an identifier of subgroup#0. For example, when the value of the first wake-up information is "0", it is used to indicate that subgroup#0 is to be awakened. Similarly, the paging subgroup indicated by the wake-up information can also be used as a paging subgroup that is not to be awakened. For example, when the value of the first wake-up information is "0", it is used to indicate that subgroup#0 is not to be awakened.

[0138] Optionally, the first terminal may determine, based on the network configuration (such as pre-configuration) or based on a pre-definition, that the paging subgroup indicated by the wake-up information is a terminal group to be awakened or a terminal group not to be awakened. Wherein, if the first terminal determines, based on the network configuration, that the paging subgroup indicated by the wake-up information is a terminal group to be awakened or a terminal group not to be awakened, the corresponding configuration may be carried in the configuration information or configuration message sent by the core network device or base station to the first terminal. If the first terminal determines, based on a pre-definition, that the paging subgroup indicated by the wake-up information is a terminal group to be awakened or a terminal group not to be awakened, the first terminal may determine, based on a local configuration (such as a factory configuration) or a definition based on a protocol, etc., that the paging subgroup indicated by the wake-up information is a terminal group to be awakened or a terminal group not to be awakened.

[0139] It can be understood that the wake-up information of any paging occasion can support indicating the wake-up status of one or more terminal groups. Among them, when the wake-up information of any paging occasion supports indicating the wake-up status of multiple terminal groups, and the terminals in the first terminal group are not exactly the same as the terminals in the second terminal group, the first wake-up information and the second wake-up information can belong to the wake-up information corresponding to the same paging occasion. For example, the first wake-up information can be part of the wake-up information corresponding to the paging occasion MO#0, and the second wake-up information can be part of the wake-up information corresponding to the paging occasion MO#1. When the wake-up information of any paging occasion only supports indicating the wake-up status of one terminal group, and the terminals in the first terminal group are not exactly the same as the terminals in the second terminal group, the first wake-up information and the second wake-up information can belong to the wake-up information corresponding to different paging occasions. For example, the first wake-up information can belong to the wake-up information corresponding to the paging occasion MO#0, and the second wake-up information can belong to the wake-up information corresponding to the paging occasion MO#1.

[0140] As an implementation of S102, when the first wake-up information indicates to wake up a terminal in the first terminal group and / or the second wake-up information indicates to wake up a terminal in the second terminal group, the first terminal may determine to wake up the first terminal. In other words, when the first terminal receives at least one of the first wake-up information and the second wake-up information indicating wake-up, it may determine to wake up the first terminal, thereby avoiding service delay or other transmission performance degradation caused by missing the wake-up information.

[0141] As an example, if at least one of the following conditions is met, the first terminal can determine to wake up the first terminal: the first wake-up information indicates to wake up the first terminal group, and the second wake-up information indicates not to wake up the second terminal group; the first wake-up information indicates not to wake up the first terminal group, and the second wake-up information indicates to wake up the second terminal group; the first wake-up information indicates to wake up the first terminal group, and the second wake-up information indicates to wake up the second terminal group.

[0142] Accordingly, if the following conditions are met, the first terminal may determine not to wake up the first terminal: the first wake-up information indicates not to wake up the first terminal group, and the second wake-up information indicates not to wake up the second terminal group.

[0143] As an implementation of S102, when the first wake-up information indicates not to wake up a terminal in the first terminal group and / or the second wake-up information indicates not to wake up a terminal in the second terminal group, the first terminal may determine not to wake up the first terminal. In other words, the first terminal may determine not to wake up the first terminal until it receives both the first wake-up information and the second wake-up information, indicating a need for wake-up, to avoid increased power consumption caused by erroneous wake-up.

[0144] As an example, if at least one of the following conditions is met, the first terminal may determine not to wake up the first terminal:

[0145] The first wake-up information instructs to wake up the first terminal group, and the second wake-up information instructs not to wake up the second terminal group;

[0146] The first wake-up information indicates not to wake up the first terminal group, and the second wake-up information indicates to wake up the second terminal group;

[0147] The first wake-up information indicates not to wake up the first terminal group, and the second wake-up information indicates not to wake up the second terminal group.

[0148] Accordingly, if the following conditions are met, the first terminal may determine to wake up the first terminal: the first wake-up information indicates to wake up the first terminal group, and the second wake-up information indicates to wake up the second terminal group.

[0149] In a possible embodiment of S102, the first terminal may determine to wake up based on one of the first wake-up information and the second wake-up information, or determine to wake up based on both the first wake-up information and the second wake-up information, based on the transmission parameters and / or transmission requirements of the first terminal. The transmission performance may include parameters such as the transmission delay, power consumption, network capacity, and performance of the first terminal, such as the current transmission delay, power consumption, and capacity of the first terminal. The transmission requirements of the first terminal may include the delay requirement, performance requirement, power consumption requirement, or network capacity requirement of the first terminal.

[0150] In one possible implementation, if the transmission performance of the first terminal is low or the first terminal requires higher transmission performance, if the current transmission delay is high or the first terminal requires lower transmission delay, or if the current network capacity is low or the first terminal requires higher network capacity, the first terminal may determine to wake up the first terminal when at least one of the first wake-up information and the second wake-up information indicates wake-up. For example, if the first terminal is a terminal that prioritizes high performance, when the actual delay of the service to be transmitted by the first terminal is greater than a preset delay threshold, the first terminal may wake up when at least one of the first wake-up information and the second wake-up information indicates wake-up.

[0151] In addition, if the current transmission power consumption is high or the first terminal requires lower transmission power consumption, the first terminal may only wake up when both the first wake-up information and the second wake-up information indicate wake-up. For example, if the first terminal prioritizes low power consumption, the first terminal will only wake up when both the first wake-up information and the second wake-up information indicate wake-up.

[0152] To support the method described in this application, in various embodiments of this application, the first terminal may send fourth information to the network device. The fourth information may include, carry, or be used to indicate the maximum number of terminal groups to which the first terminal belongs that the first terminal supports, or the fourth information is used to indicate the number of terminal groups to which the first terminal expects the first terminal to belong. The fourth information may be terminal reporting information, capability information, or other parameters, without specific limitation. Based on the fourth information reported by the first terminal, the network device may learn whether the first terminal supports or expects to monitor multiple wake-up information, and decide whether to send the first wake-up information and the second wake-up information to the first terminal.

[0153] For convenience of explanation below, the maximum number of terminal groups to which the first terminal belongs that the first terminal supports is referred to as the first number, and the number of terminal groups to which the first terminal belongs that the first terminal expects is referred to as the second number.

[0154] The first number may be a maximum number of terminal groups to which the first terminal is allowed to belong.

[0155] The second number may be a range of numbers, for example, indicating that the first terminal desires to be in at least two terminal groups to improve transmission performance of the first terminal. The second number may also be the maximum number of terminal groups to which the first terminal desires to belong, which may be determined based on the maximum number of terminal groups to which the first terminal desires to belong that the first terminal supports.

[0156] In a possible embodiment, the first quantity and / or the second quantity may be determined based on the terminal capability or performance requirements of the first terminal. The terminal capability may be, for example, the highest transmission performance supported by the terminal, or the current transmission performance of the first terminal, such as latency performance. Performance requirements may be, for example, the transmission requirements of the service of the first terminal, such as latency requirements, etc. For example, the first quantity and / or the second quantity may be associated with one or more of the power consumption requirements, coverage requirements, and performance requirements of the first terminal, and the first terminal may determine, based on the association, the first quantity and / or the second quantity corresponding to one or more of the power consumption requirements, coverage requirements, and performance requirements that the first terminal can use to determine. The association relationship may be embodied, for example, through a corresponding relationship table, or through a functional relationship, without specific limitation.

[0157] In another possible implementation, the fourth information may include one or more of the power consumption requirement, coverage requirement, and performance requirement of the first terminal, so that the network device can determine the maximum number of terminal groups to which the first terminal belongs supported by the first terminal, or determine the number of terminal groups to which the first terminal belongs expected by the first terminal, based on one or more of the power consumption requirement, coverage requirement, and performance requirement of the first terminal. For example, the network device can determine the first number and / or second number corresponding to one or more of the power consumption requirement, coverage requirement, and performance requirement that the first terminal can use to determine, based on an association between the first number and / or the second number and one or more of the power consumption requirement, coverage requirement, and performance requirement of the first terminal.

[0158] The above fourth information may be carried in terminal assistance information (UE assistance information, UAI) of the first terminal.

[0159] Optionally, the number of terminal groups to which the first terminal belongs can be determined based on the fourth information, so that the number of terminal groups to which the first terminal belongs can meet the transmission requirements of the first terminal. For example, the number of terminal groups to which the first terminal belongs does not exceed the first number. For another example, the second number is a number range, and the number of terminal groups to which the first terminal belongs belongs to this number range. As shown in Figure 7, the first terminal can send fourth information to the network device to indicate that the maximum number of terminal groups to which the first terminal belongs that the first terminal supports is greater than 1, or to indicate that the number of terminal groups to which the first terminal belongs that the first terminal expects is greater than 1. The first terminal can also receive a first wake-up indication sent by the network device to the terminal, and the first wake-up indication can be used to instruct the first terminal to determine whether to wake up the first terminal based on the wake-up information of multiple terminal groups, wherein the wake-up information of multiple terminal groups may include first wake-up information and second wake-up information, that is, the first terminal can determine to execute the process shown in Figure 3 based on the first wake-up indication. The first wake-up indication can be determined based on the fourth information.

[0160] Optionally, the fourth information may be sent based on the second wake-up instruction. The second wake-up information may be used to instruct the terminal to determine whether to wake up the first terminal based on the wake-up information of a terminal group. As shown in Figure 7, after receiving the second wake-up instruction, the first terminal may send the fourth information to the network device and receive the first wake-up instruction from the network device.

[0161] In various embodiments of the present application, the first terminal may further send fifth information, which may include, carry, be used to indicate, or be used to indicate that the first terminal supports monitoring multiple wake-up information. Based on the above implementation, the first communication device may report the fifth information to indicate whether the first terminal supports monitoring multiple wake-up information, or in other words, to indicate whether the first terminal supports repeated grouping, so that the network can decide whether to perform repeated grouping based on whether the first terminal supports monitoring multiple wake-up information, that is, decide whether to execute the method described in the present application.

[0162] As an example, the fifth information may be the same as the fourth information, or the fourth information and the fifth information may be multiplexed. For example, when the fourth information indicates that the maximum number of terminal groups to which the first terminal belongs that is supported by the first terminal is greater than 1, or indicates that the number of terminal groups to which the first terminal expects the first terminal to belong is greater than 1, it may be indicated that the first terminal supports monitoring of multiple wake-up information.

[0163] In various embodiments of the present application, the first terminal may further receive sixth information, which may include, carry, be used to instruct, or be used to determine whether the first terminal monitors multiple wake-up messages. For example, if the first terminal is configured not to monitor multiple wake-up messages, the sixth information may be used to instruct the first terminal to monitor multiple wake-up messages.

[0164] For example, the sixth information may be used to instruct the base station to send or to send multiple wake-up information including the first wake-up information and the second wake-up information. The sixth information may be carried in an RRC message, a MAC CE, a DCI, or an SIB, etc. Based on the above implementation, the first terminal may receive the sixth information and determine to monitor multiple wake-up information based on the sixth information, that is, to decide to execute the method described in this application based on the sixth information. Therefore, the network device may explicitly instruct the first terminal to monitor multiple wake-up information through signaling.

[0165] In a possible embodiment, the sixth information can be multiplexed in the same field with an indication or configuration (hereinafter referred to as the seventh information) for instructing the first terminal to monitor one wake-up information. That is, this field can be used to instruct the first terminal to monitor one or more wake-up information. Wherein, in the case where the first terminal is configured to monitor multiple wake-up information, the seventh information can be used to instruct the first terminal to monitor one wake-up information, so the first terminal can be configured to monitor only one wake-up information. For example, this field occupies one bit, and when the value of this bit is 0, it is used to configure the first terminal to monitor only one wake-up information, and when the value of this bit is 1, it is used to configure the first terminal to monitor multiple wake-up information. For another example, this field can carry the number of wake-up information monitored by the first terminal. If its value is configured to be 1, it is used to configure the first terminal to monitor only one wake-up information. If its value is configured to be greater than 1, it is used to configure the first terminal to monitor multiple wake-up information.

[0166] Optionally, the base station may also implicitly instruct the first terminal to monitor multiple wake-up messages. For example, when the number of terminal groups to which the first terminal is configured is greater than one, the base station may instruct the first terminal to monitor multiple wake-up messages. For another example, when the base station configures identifiers of multiple terminal groups for the first terminal, the base station may instruct the first terminal to monitor multiple wake-up messages.

[0167] In various embodiments of the present application, the first terminal may determine to execute the method provided by the present application according to at least one of the following, that is, determine to execute the method shown in FIG3 according to at least one of the following:

[0168] (1) The number of terminal groups supported by the first terminal is greater than 1. If the number of terminal groups supported by the first terminal is greater than 1, the first terminal may execute the method disclosed in this application.

[0169] (2) The transmission parameters and / or transmission requirements of the service of the first terminal meet the conditions for using repeated grouping. As described in this application, the transmission performance may include parameters such as the transmission delay, transmission power consumption, network capacity, and transmission performance of the first terminal, such as the current transmission delay, power consumption, capacity, and other performance parameters of the first terminal. The transmission requirements of the first terminal may include the delay requirement, performance requirement, power consumption requirement, or capacity requirement of the first terminal.

[0170] Regarding transmission latency or latency requirements, since repeated grouping can reduce the risk of increased latency due to erroneous terminal wakeup, determining whether to wake up the first terminal based on repeated grouping can reduce latency and / or meet higher latency requirements. Regarding transmission power consumption or power requirements, since repeated grouping can reduce the false alarm rate, the first terminal does not need to frequently and ineffectively wake up, which is beneficial for energy conservation. Regarding network capacity or network capacity requirements, when the channel quality is poor, it can make it difficult for the terminal to connect to the base station, resulting in a small number of terminals that the base station can serve. Therefore, repeated grouping can be used to increase the probability of the terminal entering the RRC connected state through the random access process, which is beneficial for improving network capacity. Regarding transmission performance or performance requirements, when repeated grouping is used, the first terminal can combine two or more messages for processing. For example, if the first wake-up message and the second wake-up message are sent repeatedly, and the channel is poor when the first wake-up message is transmitted, the first terminal receives a poor signal for the first wake-up message, while the channel is good when the second wake-up message is transmitted, the first terminal can combine these two signals for processing. Since the wake-up messages in different terminal groups are the same during repeated transmissions, the first terminal can decide whether to wake up based on the two wake-up messages, reducing the probability of missed detection.

[0171] Taking latency requirements as an example, performance parameters that meet the conditions for using repeated grouping include, for example, that the latency required by the service to be transmitted by the first terminal is less than or equal to (or not greater than) a latency threshold. For example, when the first terminal determines that the latency required by the service is less than the latency threshold, it can determine whether to wake up the first terminal based on the method described in this application. That is, when the service transmission latency requirement is high (or the service latency requirement is low), the first terminal can determine whether to wake up the first terminal based on the first wake-up information and the second wake-up information.

[0172] The latency threshold may be configured by the network device or may be predefined. If the latency threshold is configured by the network device, the configuration information for the latency threshold may be carried in a message sent by the network device to the first terminal. For example, if the network device is a base station, the message may be, for example, an RRC message, a MAC CE, a DCI, or a SIB, without specific limitation.

[0173] (3) The channel information of the first terminal meets the conditions for using repeated grouping, such as channel state information (CSI). The channel information of the first terminal meets the conditions for using repeated grouping, for example, including that the CSI of the first terminal is less than or equal to (or not greater than) a CSI threshold. For example, the first terminal can determine whether to wake up the first terminal based on the method shown in this application when the CSI is less than or equal to (or not greater than) the CSI threshold. That is, when the channel state is poor, the first terminal can determine whether to wake up the first terminal based on the first wake-up information and the second wake-up information.

[0174] The CSI threshold may be configured by the network device or predefined. If the CSI threshold is configured by the network device, the configuration information of the CSI threshold may be carried in a message sent by the network device to the first terminal. For example, if the network device is a base station, the message may be, for example, an RRC message, a MAC CE, a DCI, or a SIB, without specific limitation.

[0175] (4) The base station instructs the first terminal to monitor multiple wake-up information. The base station may explicitly instruct the first terminal to monitor multiple wake-up information. For example, the base station instructs the first terminal to monitor multiple wake-up information through the aforementioned sixth information. In addition, the base station may also implicitly instruct the first terminal to monitor multiple wake-up information. For example, when the number of terminal groups to which the first terminal belongs configured by the base station is greater than 1, or when the base station configures identifiers of multiple terminal groups for the first terminal, the first terminal may be instructed to monitor multiple wake-up information in a mode manner.

[0176] When at least one of the above conditions (1) to (4) is met, the first terminal and the base station can use the method of the embodiment of the present application to determine whether to wake up the first terminal, so as to reasonably determine whether to execute the method shown in the present application.

[0177] In various embodiments of the present application, the first terminal may determine not to execute the method provided in the present application based on at least one of the following. Not executing the method provided in the present application may mean that the first terminal still determines whether to wake up the first terminal based only on one wake-up message. That is, determining to execute the method shown in FIG3 based on at least one of the following:

[0178] (1) A first terminal receives a wake-up instruction from a network device, where the wake-up instruction is used to instruct the first terminal to exit multiple repeated groupings, for example, indicating that the number of terminal groups to which the first terminal belongs is 1. For another example, the wake-up instruction can be used to instruct the first terminal not to use repeated groupings, that is, to indicate that the first terminal does not belong to multiple terminal groups. Alternatively, the wake-up instruction can be used to instruct one or more terminals to exit repeated groupings, or to instruct one or more terminals not to use repeated groupings, where the one or more terminals include the first terminal.

[0179] (2) The performance parameters of the service of the first terminal do not meet the conditions for using repeated grouping, or in other words, the performance parameters of the service of the first terminal meet the conditions for not using repeated grouping. For example, the first terminal may not perform the method provided in this application when the service delay is greater than or equal to (or not less than) the delay threshold. That is, when the service delay is low, the first terminal may not perform the method provided in this application. The delay threshold can be determined by referring to the method in this application and will not be described in detail.

[0180] (3) The channel information of the first terminal does not meet the conditions for using repeated grouping, or in other words, the channel information of the first terminal meets the conditions for not using repeated grouping. For example, the first terminal may not perform the method provided in this application when the CSI is greater than or equal to (or not less than) a CSI threshold. That is, when the channel state is good, the first terminal may not perform the method provided in this application. The CSI threshold can be determined by referring to the method in this application and will not be described in detail.

[0181] (4) The number of terminal groups supported or expected by the first terminal is not greater than 1. For example, if the first terminal indicates in the UAI that the number of terminal groups supported or expected is 1, the first terminal may not execute the method provided in this application.

[0182] When at least one of the above conditions (1) to (4) is met, the first terminal and the base station may not use the method of the embodiment of the present application to determine whether to wake up the first terminal. In this case, the first terminal may monitor a wake-up message to determine whether to wake up.

[0183] The above is an introduction to the communication method and related embodiments provided by this application. Based on the method shown in this application, the terminal device can determine the wake-up state of the first terminal based on the wake-up information corresponding to at least two terminal groups (including the first wake-up information and the second wake-up information), which can more accurately determine the wake-up state and avoid false alarms or missed detections.
