Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a communication method, device and storage medium. Background Art

[0002] In wireless communication systems, most of the power consumption of terminal devices is used for channel monitoring. In order to save power, the terminal device can be put into a dormant state, but if it is put into a dormant state for too long, it will increase the information processing or transmission delay. Therefore, the 3rd generation partnership project (3GPP) introduced a low power wake up signal (LP WUS or ).

[0003] In the case where the terminal device supports LP WUS, if LP WUS indicates to wake up the main radio (MR), after waking up the MR, the terminal device can monitor the paging occasion (PO) through the MR. If LP WUS indicates not to wake up the MR, the MR remains in the off state and the wake-up receiver (such as LP WUR) is enabled, thereby saving power consumption. Furthermore, for the scenario where one PO corresponds to multiple terminal devices, those skilled in the art have proposed that the multiple terminal devices corresponding to the PO can be grouped to avoid all terminal devices in the PO from monitoring the PO, which can further save power consumption.

[0004] At present, the terminal devices with the same paging rate can be grouped into one group. According to the simulation results, the larger the paging rate of the terminal device, the less energy benefit of using MR wakeup, or even a negative number, which may cause all the terminal devices to be divided into one paging sub-group, thereby increasing the false alarm rate of the terminal device and reducing the energy benefit. Summary of the invention

[0005] The embodiments of the present application disclose a communication method, an apparatus and a storage medium, which can report a fine-grained paging rate, so that the paging rates of terminal devices in a paging subgroup are closer, which can reduce the probability of terminal devices being mis-paged and save power consumption.

[0006] In a first aspect, the embodiment of the present application discloses a first communication method, which can be executed by a terminal device, or by a component in the terminal device (for example, a processor, a chip, or a chip system, etc.), or by a logic module or software that can implement all or part of the functions of the terminal device. The following is an example of a terminal device, and the communication method includes:

[0007] Sending first information to a network device; receiving second information from the network device. The first information includes first sub-paging information and second sub-paging information, the first sub-paging information is used to indicate a first sub-paging rate corresponding to a first granularity, the second sub-paging information is used to indicate a second sub-paging rate corresponding to a second granularity, the first granularity is greater than the second granularity, the first sub-paging rate and the second sub-paging rate are used to determine a first paging rate, the first paging rate is used to assist in determining a paging sub-group of the terminal device; the second information includes an identifier of the paging sub-group of the terminal device.

[0008] In a second aspect, the embodiment of the present application discloses a second communication method, which can be executed by a network device, or by a component in the network device (for example, a processor, a chip, or a chip system, etc.), or by a logic module or software that can implement all or part of the network device functions. The following is an example of a network device, and the communication method includes:

[0009] Receive first information of a terminal device, the first information including first sub-information and second sub-information; determine a first sub-paging rate corresponding to a first granularity based on the first sub-information, and determine a second sub-paging rate corresponding to a second granularity based on the second sub-information, the first granularity being greater than the second granularity; determine a first paging rate based on the first sub-paging rate and the second sub-paging rate, the first paging rate being used to assist in determining a paging sub-group of the terminal device; and send second information to the terminal device, the second information including an identifier of the paging sub-group of the terminal device.

[0010] It can be understood that by implementing the first communication method or the second communication method, the terminal device sends the first information to the network device. The first information includes the first sub-paging information and the second sub-paging information, the first sub-paging information and the second sub-paging information respectively use different granularities to represent the sub-paging rate, and the first granularity of the first sub-paging rate indicated by the first sub-paging information is greater than the second granularity of the second sub-paging rate indicated by the second sub-paging information. In this way, by reporting the second sub-paging rate, a paging rate with finer granularity can be reported. The first sub-paging rate and the second sub-paging rate can determine the first paging rate, and the first paging rate can be used to assist the network device in determining the paging sub-groups of the terminal device, which is beneficial to subdividing the paging sub-groups of the terminal device and can save power consumption.

[0011] In combination with the first aspect, in some feasible examples, the first paging rate is equal to the sum of the first sub-paging rate and the second sub-paging rate.

[0012] In combination with the second aspect, in some feasible examples, determining the first paging rate based on the first sub-paging rate and the second sub-paging rate includes: acquiring the sum of the first sub-paging rate and the second sub-paging rate to obtain the first paging rate.

[0013] In an embodiment of the present application, the paging rate corresponding to the sum of the first sub-paging rate and the first granularity may be referred to as the third sub-paging rate. The gear of the third sub-paging rate is one gear higher than the first sub-paging rate. In this way, when the first paging rate is equal to the sum of the first sub-paging rate and the second sub-paging rate, the first paging rate is greater than the first sub-paging rate and less than the third sub-paging rate. In other words, the first paging rate may be reported between the first sub-paging rate and the third sub-paging rate, that is, compared with reporting the paging rate of the first granularity, a paging rate of finer granularity is reported, which is conducive to subdividing the paging sub-groups of the terminal device, can reduce the probability of the terminal device being mis-paged, and saves power consumption.

[0014] In combination with the first aspect or the second aspect, in some feasible examples, the first information further includes first subtype information and second subtype information, the first subtype information is used to indicate the first granularity, and the second subtype information is used to indicate the second granularity. In this way, the first granularity can be determined by the first subtype information, and the second granularity can be determined by the second subtype information. Then, the first paging rate is determined according to the first granularity and the first sub-paging information, and the second paging rate is determined according to the second granularity and the second sub-paging information.

[0015] In combination with the first aspect or the second aspect, in some feasible examples, the first sub-paging information and the first sub-type information are indicated by different fields in the first byte, and the second sub-paging information and the second sub-type information are indicated by different fields in the second byte. In this way, signaling can be saved. And the first sub-type information and the first sub-paging information associated with the first granularity are indicated by one byte, and the second sub-type information and the second sub-paging information associated with the second granularity are indicated by another byte, which can improve the efficiency of determining the paging rate.

[0016] In combination with the first aspect, in some feasible examples, the second sub-paging information includes first-level paging information and second-level paging information; the first-level paging information is used to indicate a first-level paging rate corresponding to a first-level granularity, the second-level paging information is used to indicate a second-level paging rate corresponding to a second-level granularity, the first-level paging rate and the second-level paging rate are used to indicate the second sub-paging rate, the first-level granularity and the second-level granularity are used to determine the second granularity, and the first-level granularity is greater than the second-level granularity.

[0017] In combination with the second aspect, in some feasible examples, the second sub-paging information includes first-level paging information and second-level paging information; the communication method also includes: determining a first-level paging rate corresponding to the first-level granularity based on the first-level paging information, and determining a second-level paging rate corresponding to the second-level granularity based on the second-level paging information; wherein the first-level granularity and the second-level granularity are used to determine the second granularity; and determining the second sub-paging rate based on the first-level paging rate and the second-level paging rate.

[0018] In the embodiment of the present application, the first level granularity can be understood as coarse granularity, and the second level granularity can be understood as fine granularity. In this way, the first level paging rate determined by the coarse granularity and the second level paging rate determined by the fine granularity are reported, so that the granularity of the reported paging rate is smaller, which is conducive to subdividing the paging sub-groups of the terminal device, can reduce the probability of the terminal device being mis-paged, and save power consumption.

[0019] In combination with the first aspect, in some feasible examples, the second sub-paging rate is equal to the sum of the first-level paging rate and the second-level paging rate, and the second granularity is equal to the sum of the first-level granularity and the second-level granularity.

[0020] In combination with the second aspect, in some feasible examples, the second granularity is equal to the sum of the first-level granularity and the second-level granularity; determining the second sub-paging rate based on the first-level paging rate and the second-level paging rate includes: obtaining the sum of the first-level paging rate and the second-level paging rate to obtain the second sub-paging rate.

[0021] In an embodiment of the present application, the paging rate corresponding to the sum of the first-level paging rate and the first-level granularity can be called the third-level paging rate. The gear of the third-level paging rate is one gear higher than the first-level paging rate. In this way, when the second sub-paging rate is equal to the sum of the first-level paging rate and the second-level paging rate, the second sub-paging rate is greater than the first-level paging rate and less than the third-level paging rate. In other words, the second paging rate can be reported between the first-level paging rate and the third-level paging rate, that is, a paging rate with finer granularity is reported compared to the paging rate reported at the first-level granularity, which is conducive to subdividing the paging sub-groups of the terminal device, can further reduce the probability of the terminal device being mis-paged, and save power consumption.

[0022] In combination with the first aspect or the second aspect, in some feasible examples, the first granularity is the original granularity.

[0023] Among them, the original granularity can be understood as the granularity of the pre-configuration or original configuration of the network device, such as 5%. The second granularity can be understood as the increased granularity, that is, the newly configured granularity. It can be understood that when the first granularity is the original granularity, increasing the second granularity is equivalent to improving the original paging rate reporting mechanism. When the first granularity is greater than the second granularity, the second sub-paging rate corresponding to the reported second granularity, that is, reporting a paging rate with finer granularity, is conducive to subdividing the paging sub-groups of the terminal device, can reduce the probability of the terminal device being mis-paged, and save power consumption.

[0024] In a third aspect, the embodiment of the present application discloses a third communication method, which can be executed by a terminal device, or by a component in the terminal device (for example, a processor, a chip, or a chip system, etc.), or by a logic module or software that can implement all or part of the functions of the terminal device. The following is an example of a terminal device, and the communication method includes:

[0025] Sending first information to a network device; receiving second information from the network device. The first information is used to indicate a first paging rate or a second paging rate; the second paging rate corresponds to a first granularity, the first paging rate corresponds to a second granularity, the first granularity is greater than the second granularity, the first paging rate or the second paging rate is used to assist in determining a paging subgroup of the terminal device; and the second information includes an identifier of the paging subgroup of the terminal device.

[0026] In a fourth aspect, an embodiment of the present application discloses a fourth communication method, which can be executed by a network device, or by a component in the network device (e.g., a processor, a chip, or a chip system, etc.), or can be executed by a logic module or software that can implement all or part of the network device functions. Taking a network device as an example, the communication method includes: receiving first information of a terminal device; determining a first paging rate or a second paging rate based on the first information, the second paging rate corresponding to a first granularity, the first paging rate corresponding to a second granularity, the first granularity being greater than the second granularity, the first paging rate or the second paging rate being used to assist in determining a paging subgroup of the terminal device; sending second information to the terminal device, the second information including an identifier of a paging subgroup of the terminal device.

[0027] It can be understood that by implementing the third communication method or the fourth communication method, the terminal device sends the first information to the network device. The first information is used to indicate the first paging rate corresponding to the first granularity or the second paging rate corresponding to the second granularity, and the first granularity is greater than the second granularity. In this way, a finer granularity first paging rate can be reported. The first paging rate can be used to assist in determining the paging subgroups of the terminal device, which is beneficial to subdividing the paging subgroups of the terminal device and can save power consumption.

[0028] In combination with the third aspect or the fourth aspect, in some feasible examples, the second granularity corresponds to multiple first paging rates, the first granularity corresponds to multiple second paging rates, and the multiple second paging rates include the maximum paging rate and the minimum paging rate among the multiple first paging rates.

[0029] In combination with the third aspect, in some feasible examples, the first information includes a first number of bits or a second number of bits; the first paging rate is determined by the first number of bits and the second granularity, and the second paging rate is determined by the second number of bits, the second granularity and the first granularity.

[0030] In combination with the fourth aspect, in some feasible examples, the first information includes a first number of bits or a second number of bits; the communication method also includes: determining the first paging rate based on the first number of bits and the second granularity; determining the second paging rate based on the second number of bits, the second granularity and the first granularity.

[0031] In the case where the second granularity is smaller than the first granularity, the first paging rate may be specifically located between the first gear and the second gear in the second paging rate, so that the first paging rate may be determined based on the first number of bits and the second granularity. The number of first paging rates that are increased is related to the second granularity, and after the first paging rate is increased, the value corresponding to the second number of bits will be greater than the number of gears corresponding to the second paging rate, so that the second paging rate may be determined based on the second number of bits, the second granularity, and the first granularity.

[0032] In combination with the third aspect or the fourth aspect, in some feasible examples, the first paging rate and the second paging rate both occupy M bits, the difference between the number of paging rates corresponding to the second granularity and the number of repeated paging rates is less than or equal to a first value, the first value is equal to the difference between the total number of paging rates corresponding to M and the number of paging rates corresponding to the first granularity, and the repeated paging rate is the repeated paging rate in the paging rate corresponding to the first granularity and the paging rate corresponding to the second granularity. In this way, the number of the first paging rate of the refined granularity is increased without deleting the second paging rate and modifying the number of bits occupied by the paging rate.

[0033] In combination with the third aspect or the fourth aspect, in some feasible examples, the first information includes first type information; when the first information is used to indicate the first paging rate, the first type information is used to indicate the second granularity; when the first information is used to indicate the second paging rate, the first type information is used to indicate the first granularity. That is, the first type information is used to determine whether the report is based on the first granularity or the second granularity, and then the first paging rate or the second paging rate can be determined according to the reported first paging information.

[0034] In combination with the third aspect or the fourth aspect, in some feasible examples, the first information includes first paging information, the first paging information is used to indicate the first paging rate or the second paging rate, and the first paging information and the first type information are indicated by different fields of the third byte. In this way, signaling can be saved. And the first type information and the first paging information correspond to the same granularity, which can improve the efficiency of determining the paging rate.

[0035] In combination with the third aspect or the fourth aspect, in some feasible examples, the first granularity is the original granularity. In this way, the second paging rate is reported based on the original granularity, or the first granularity is reported based on the newly configured granularity. If the first granularity is larger than the second granularity, the original granularity is finer than the newly configured granularity, so a finer granularity paging rate is used when reporting the first paging rate, which is conducive to subdividing the paging sub-groups of the terminal device, can reduce the probability of the terminal device being mis-paged, and save power consumption.

[0037] In a sixth aspect, the present application discloses a fifth communication device, which may be a network device or a terminal device, etc., or may include devices in these devices, such as a chip, or a chip system, or a circuit, etc., or a device capable of implementing related functions. The communication device includes a processor, which is used to execute instructions stored in a memory, and when the instructions are executed, the communication method in the first aspect, the second aspect, the third aspect, or the fourth aspect and any feasible example thereof is implemented.

The wake-up receiver is used to detect paging messages or wake-up information from other devices. Compared with MR, it has lower power consumption, so it can be called a low power receiver (LPR), or a low power wake-up receiver (LPWUR), or a low power radio (LPR), or a low power wake-up radio (LPWUR).

[0069] In the embodiment of the present application, the terminal device may be a power consumption sensitive device, or in other words, the terminal device has a low power consumption requirement. Optionally, the terminal device may be a static, restricted and / or slow moving device.

[0071] The embodiments of the present application do not limit the device form of the terminal device. The device for realizing the function of the terminal device may be a terminal device; or it may be a device that can support the terminal device to realize the function, such as a chip system.

In the embodiments of the present application, the chip system may be composed of a chip, or may include a chip and other discrete devices. The following description is sometimes made with a terminal, and the UE is taken as an example. It should be understood that the terminal and the UE may be replaced with any of the above-mentioned terminal devices.

[0072] In the embodiment of the present application, the network device 110 may be an access network (AN) device or a radio access network (RAN) device, and may also be referred to as a RAN node (or device). The access network device is used to help the terminal device achieve wireless access (or access). In some scenarios, if no specific network device is described, the network device may be understood as an access network device.

[0073] Optionally, the access network equipment may include, but is not limited to: access point (AP), enhanced nodeB (eNB), home base station (e.g., home evolved NodeB, or home Node B, HNB), baseband unit (BBU), next generation base station (NR nodeB, gNB), transmission reception point (TRP), transmission point (TP) or some other access node, such as wireless relay node, wireless backhaul node, etc. The AN / RAN node may be one or more antenna panels, or may be a network node constituting a gNB or a transmission point, such as a BBU or a distributed unit (DU), etc., or may be a device that performs RAN functions in communication systems such as D2D, V2X, M2M, U2U, etc. The AN / RAN node may be a wireless controller in a cloud radio access network (CRAN) scenario, or may be an open access network (open RAN, O-RAN or ORAN) device, or may be an access network device in a communication system evolved after the 5G communication system, for example, an xNodeB in a 6G communication system, or may be an access network device in a PLMN network evolved after the 5G communication system, etc., without limitation herein.

[0074] All or part of the functions of the access network device in this application may also be implemented by software functions running on hardware, or by virtualization functions instantiated on a platform (such as a cloud platform). The access network device in this application may also be a logical node, logical module or software that can implement all or part of the functions of the access network device.

[0075] Optionally, multiple access network devices collaborate to assist the terminal device in achieving wireless access, and different access network devices respectively implement part of the functions of the base station. For example, the access network device may be a centralized unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU). The CU and DU may be separately configured, or may be included in the same network element, such as the CU and DU are included in the baseband unit (BBU). The RU may be included in a radio frequency device or a radio frequency unit, such as a remote radio unit (RRU), an active antenna unit (AAU), or a remote radio head (RRH). It is understandable that the access network device may be a device including a CU node, or may be a device including a DU node, or may be a device including a CU node and a DU node.

[0076] In different systems, CU (or CU-CP and CU-UP), DU or RU may also have different names, but those skilled in the art can understand their meanings. For example, in the ORAN system, CU may also be called O-CU (open CU), DU may also be called O-DU, CU-CP may also be called O-CU-CP, CU-UP may also be called O-CU-UP, and RU may also be called O-RU. For the convenience of description, this application takes CU, CU-CP, CU-UP, DU and RU as examples for description. Any unit of CU (or CU-CP, CU-UP), DU and RU in this application may be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

[0077] The embodiment of the present application does not limit the form of the access network device. The device for implementing the function of the access network device may be the access network device; or it may be a device that can support the access network device to implement the function, such as a chip system. The device may be installed in the access network device or used in conjunction with the access network device.

[0078] It should be stated that in Figure 1 In the network architecture shown, although access network equipment and terminal equipment are shown, the application scenario may not be limited to including access network equipment and terminal equipment. For example, it may also include equipment for carrying virtualized network functions, etc. These are obvious to technical personnel in this field and will not be elaborated here.

[0079] also, Figure 1 The number and type of network devices and terminal devices included in the network architecture shown are only examples, and the embodiments of the present application are not limited thereto. For example, more or fewer terminal devices communicating with the network devices may be included. For another example, more or fewer network devices communicating with the terminal devices may be included. For the sake of simplicity, they are not described one by one in the drawings.

[0080] Optionally, the communication system may also include Figure 1 Network devices not shown in the figure, for example, core network (CN) equipment, data network (data network) equipment, etc.

[0081] In different communication systems, core network equipment (hereinafter referred to as core network) may correspond to different equipment. For example, in 3G communication system, it may correspond to GPRS serving support node (SGSN) and / or GPRS gateway support node (GGSN); in 4G communication system, it may correspond to mobility management entity (MME) and / or serving gateway (S-GW); in 5G communication system, it may correspond to the above-mentioned policy control function (PCF) network element, unified data management (UDM) network element, application function (AF) network element, access and mobility management function (AMF) network element, session management function (SMF) network element, location management function (LMF) network element, user plane function (UPF) network element, etc. In this article, core network equipment is sometimes referred to as core network.

[0082] Among them, the UPF network element is responsible for managing the transmission of user plane data and service quality (QoS) control, traffic statistics and other functions. It can perform user data packet forwarding according to the routing rules of the session management network element, such as sending uplink data to the data network or other user plane network elements, and forwarding downlink data to other user plane network elements or (R)AN network elements.

[0083] The AMF network element is responsible for user access management, security authentication, and mobility management. The LMF network element is responsible for managing and controlling the positioning service requests of the target terminal and processing positioning-related information. The SMF network element is responsible for session management, allocating resources for sessions of terminal devices and releasing resources. The UDM network element is responsible for context management of user contracts. For example, it stores the contract information of terminal devices. The PCF network element is responsible for user policy management. Similar to the policy and charging rules function (PCRF) network element in LTE, it is mainly responsible for the generation of policy authorization, service quality, and charging rules, and sends the corresponding rules to the UPF network element through the SMF network element to complete the installation of the corresponding policies and rules. The AF network element can be a third-party application control platform, or it can be the operator's own equipment. The AF network element is responsible for implementing application management and can provide services for multiple application servers.

[0084] In the embodiment of the present application, the data network device is used to provide business services to users. Generally, the client is a terminal device and the server is a data network device. The data network provided by the data network device may include a private network, such as a local area network. The data network may include an external network that is not managed by an operator, such as the Internet. The data network may include a proprietary network jointly deployed by operators, such as a network that provides Internet protocol multimedia subsystem (IMS) services.

[0085] In some embodiments, the network device and the terminal device may also be referred to as a communication device, which may be a general device or a dedicated device, and the embodiments of the present application do not specifically limit this.

[0086] In order to facilitate the understanding of the content of this solution, some concepts or technologies involved in the embodiments of this application are explained below to facilitate understanding by those skilled in the art. This part is only for ease of understanding and cannot be regarded as a specific limitation of this application.

[0087] (1) System information is the cell-level information that network equipment periodically broadcasts on the broadcast control channel (BCCH). After the terminal device searches for a cell and completes downlink synchronization with the cell, it needs to obtain the system information of the cell in order to access the cell and work in the cell.

[0088] At present, the system information of 5G NR includes the master information block (MIB) and multiple system information blocks (SIB). Among them, SIB currently includes 14 types of system information blocks from SIB1 to SIB14, and more SIBs may be introduced in the future. MIB includes some necessary physical layer information. For example, MIB can include the system frame number (SFN), which is carried by the systemFrameNumber field and is used for synchronization between the terminal device and the network side.

[0089] It should be noted that this application only lists the information related to this application included in the MIB. In fact, the MIB may also include other information, such as subcarrier spacing, subcarrier offset, demodulation reference signal (DMRS) position information, etc. Please refer to the relevant instructions in the standard and will not be described in detail here.

[0090] (2) Paging: It is used to notify idle or inactive terminal devices to establish a called service, or to notify terminal devices that system information of the communication system has changed and the terminal devices need to re-read the changed system broadcast message, or to notify terminal devices to receive earthquake and tsunami warning system (ETWS) information.

[0091] The terminal device may receive paging messages periodically, and this period is called a paging cycle. Optionally, when a discontinuous reception (DRX) technology is used, the paging cycle may be a DRX cycle of the UE, for example, 1.28s or 2.56s. That is, the terminal device is awakened when the DRX cycle arrives, and is used to obtain paging messages.

[0092] The specific time when the terminal device receives the paging message is called the paging occasion PO, which is determined by the network device and configured to the terminal device. In a paging cycle, multiple paging frames (PF) may be included, and each PF includes multiple POs. Among them, each PO corresponds to an SFN, and a PO corresponds to one or more terminal devices, that is, the paging message transmitted in a PO can be effective for one or more terminal devices.

[0093] For example, please refer to Figure 3 , Figure 3 Schematic diagram of a paging cycle structure proposed in the embodiment of the present application. Figure 3 As shown, in one paging cycle, there may be 4 PFs, namely PF1, PF2, PF3 and PF4, and each PF includes 2 POs, namely PO1 and PO2. Among them, PO1 corresponds to 6 terminal devices, namely UE#1-UE#6.

[0094] Optionally, each PF may also have an offset.

[0095] Optionally, each PF corresponds to multiple synchronization signal / physical broadcast channel blocks (SSBs).

[0096] The paging message is a type of downlink control information (DCI), which can be a DCI scrambled by a paging radio network temporary identity (P-RNTI) (such as DCI1_0). The paging message is a radio resource control (RRC) message carried on the physical downlink shared channel (PDSCH), which is used to send a call request to a terminal device in the RRC idle state to notify the terminal device to enter random access.

[0097] The process of receiving a paging message by a terminal device is as follows: calculating the locations PO and PF where the paging message may be sent; detecting the paging message based on PO and PF. Currently, the method for determining PF can refer to the following formula (1), and the method for determining PO can refer to the following formula (2).

[0098] (SFN + PF_offset) mod T = (T div N)*(UE_ID mod N) (1)

[0099] i_s = floor (UE_ID / N) mod Ns (2)

[0100] Among them, "div" is integer division calculation, " / " is division calculation. "*" is multiplication calculation, and "+" is addition calculation. floor() means rounding down. "mod" means modulo operation, that is, the remainder after the two numbers before and after mod are divided. SFN is the system frame number, and its value range is 0-1023. T is the paging cycle of the terminal device (such as DRX cycle), which is a constant, such as 32, 64, 128, 256, etc., in ms. N is the number of PFs in T. Ns is the number of POs in PF, such as Figure 3 As shown, Ns of PF1 is 2. PF_offset is the offset of PF. UE_ID is the identifier of the terminal device, and i_s is used to indicate that the PO is the previous PO of the PO in the PF. That is, i_s+1 indicates the PO of the PO that sends the paging message of the terminal device in the PF.

[0101] This application does not limit the identification of the terminal device. The identification of the terminal device can be a UE-level identification, such as an international mobile subscriber identification number (IMSI), an international mobile equipment identity (IMEI), a temporary mobile station identity (S-TMSI), etc., or it can be a cell-level or group-level identification, such as a cell-radio network temporary identity (C-RNTI), etc.

[0102] Optionally, the value corresponding to the identifier of the terminal device may be a modulus between the identifier of the terminal device and a first threshold value, wherein the first threshold value may be 1024 or 4096. Exemplarily, UE_ID=IMSI mod 1024, wherein the IMSI may be an S-TMSI in a 5G system.

[0103] From the above formulas (1) and (2), it can be seen that for a certain terminal device, by calculating the PF, the SFN of the paging message received by the terminal device can be known, and by calculating i_s, it can be known that the PO of the terminal device is the i_s+1th PO in the PF. In other words, the terminal device can calculate which PO of which PF it is monitoring the DCI scrambled by the P-RNTI based on formulas (1) and (2).

[0104] (3) Low power wake-up signal LP WUS is a signal that can be monitored when the terminal device is within the coverage of LP WUS. Figure 2 As shown, LP WUS can indicate to wake up the main receiver MR or not. When the terminal device turns off MR and turns on LR, it can monitor LP WUS. If LP WUS indicates to wake up MR, after waking up MR, the terminal device can monitor PO through MR. If LP WUS indicates not to wake up MR, MR remains turned off.

[0105] In the embodiment of the present application, when the terminal device is monitoring the LP WUS, the wake-up receiver is in the on state, and the terminal device can monitor the LP WUS through the wake-up receiver. The wake-up receiver being in the on state can also be described as the wake-up receiver being in the awake state. Correspondingly, the wake-up receiver being in the off state can also be described as the wake-up receiver being in the sleep state.

[0106] When the network device needs to page the terminal device, the terminal device in the group to which the terminal device belongs can be awakened through LP WUS, or the terminal device in the group to which the terminal device belongs can be notified through LP WUS to wake up MR to listen to PO. In the embodiment of the present application, waking up MR can also be described as waking up the terminal device, and the two descriptions can be used interchangeably.

[0107] In the embodiment of the present application, the terminal device monitoring PO and the terminal device monitoring DCI scrambled by P-RNTI under PO have the same meaning and can be used interchangeably. Or it can be described as monitoring paging.

[0108] In the embodiment of the present application, when the terminal device is monitoring PO, MR is in the on state, and the terminal device can monitor PO through MR. Among them, MR in the on state can also be described as MR in the awake state. Correspondingly, MR in the off state can also be described as MR in the sleep state.

[0109] It should be noted that the terminal device will not monitor PO while monitoring LP WUS, and will not monitor LP WUS while monitoring PO. In other words, the terminal device does not monitor LP WUS and PO at the same time, but monitors one of LP WUS or PO.

[0110] It should also be noted that, in the embodiments of the present application, the following descriptions represent the same meaning and can be used interchangeably: "the terminal device listens to LP WUS", "the terminal device is in a state of listening to LP WUS", "the terminal device is in a state of listening to LP WUS", "the terminal device turns off MR and uses LR to listen to LP WUS", "the terminal device enters an ultra-deepsleep mode". LP WUS can also be described as a wake-up signal.

[0111] In the embodiments of the present application, the following descriptions represent the same meaning and can be used interchangeably: "The terminal device stops listening to LP WUS", "The terminal device exits the state of listening to LP WUS", "The terminal device exits the LP WUS listening state", "The terminal device listens to PO", "The terminal device is in the state of listening to PO", "The terminal device is in the PO listening state", "The terminal device is in the traditional PO listening state", "The terminal device turns off LR and uses MR to listen to PO", "The terminal device listens to DCI under PO", "The terminal device listens to DCI encrypted by P-RNTI under PO".

[0112] In the embodiment of the present application, the content indicated by LP WUS can be any of the following: "Stop listening to LP WUS", "Exit listening to LP WUS", "Exit the state of listening to LP WUS", "Exit the state of listening to LP WUS", "Exit the LP WUS listening state", "Listen to PO", "Enter listening to PO", "Enter the state of listening to PO", "Enter the PO listening state", "Enter the traditional PO listening state", "State transition", "Perform state transition", "Switch from listening to LP WUS to listening to PO", "Switch from the state of listening to LP WUS to the state of listening to PO", "Switch from the LP WUS listening state to the PO listening state". The above contents indicated by LP WUS can represent the same meaning and can be used interchangeably.

[0113] In the embodiment of the present application, the power consumption of the terminal device in a deep sleep state is taken as a reference, that is, the power consumption of the terminal device in the deep sleep state is taken as 1 unit. The power consumption of the terminal device in different states can be shown in Table 1.

[0114] Table 1

[0115]

[0116] When the terminal device is in the state of monitoring PO, it needs to monitor the PDCCH encrypted by P-RNTI. If the PDCCH encrypted by P-RNTI is not monitored, in this case, the power consumption of the terminal device monitoring PO is 100 units. If the terminal device monitors and receives the PDCCH, it can receive the PDSCH on the time-frequency resources indicated by the DCI in the PDCCH. In this case, the power consumption of the terminal device monitoring PO is 300 units. Among them, the PDSCH includes a paging message, and the paging message indicates whether the terminal device is paged. In an embodiment of the present application, the terminal device monitoring the PDCCH encrypted by P-RNTI can have the same meaning as the terminal device monitoring the DCI encrypted by P-RNTI, and can be used interchangeably.

[0117] The existing simulation results show that each time the terminal device performs a state transition, the power consumption is in the range of 15000 units to 40000 units. Among them, "state transition" can refer to the terminal device switching from listening to PO to listening to LP WUS, or the terminal device switching from listening to LP WUS to listening to PO. It can be seen that the power consumption of the terminal device for state transition is much greater than the power consumption of the terminal device for listening to PO.

[0118] (4) Paging probability and false alarm rate.

[0119] In the embodiment of the present application, the paging rate refers to the probability that the terminal device parses and monitors its own paging message. The false alarm rate refers to the probability that the terminal device parses and monitors a paging message that is not the paging message of the terminal device. Both the paging rate and the false alarm rate can be values ​​greater than or equal to 0 and less than or equal to 1. Usually, the paging rate and the false alarm rate are expressed in percentages. Optionally, the sum of the false alarm rate and the paging rate is 1.

[0120] For terminal devices associated with the same PO, they all need to monitor the DCI scrambled by P-RNTI under the PO, which leads to a high false alarm rate. Figure 3 As shown, UE#1-UE#6 need to monitor the DCI encrypted by P-RNTI at PO1 and receive the paging message on the time-frequency domain resources indicated by the DCI. Assuming that the network device only pages UE#1-UE#3 at PO1, UE#1-UE#3 can determine that they are paged through the paging message, but UE4-UE6 can determine that they are not paged through the paging message. In this case, the number of false alarms for UE#4-UE#6 is increased by 1. If this happens frequently, the false alarm rate will increase, which will increase the power consumption of the terminal device.

[0121] Please refer to Figure 4 , Figure 4is a schematic diagram of a mapping relationship between a paging rate and energy saving gain provided in an embodiment of the present application. Figure 4 In the figure, the solid line represents the paging rate and energy benefit when the MR performs radio resource management (RRM) during the paging cycle, and the dotted line represents the paging rate and energy benefit when the MR does not perform RRM. The energy benefit of performing RRM specifically refers to the energy benefit obtained by using LP WUS to wake up the MR. Figure 4 As shown in FIG. 1 , the greater the paging rate of the terminal device, the less energy benefit is obtained by using LP WUS to wake up the MR, and the energy benefit may even be negative.

[0122] To solve this problem, UEs associated with the same PO can be grouped. Figure 3 UE1-UE6 associated with PO1 in PF1 are divided into two groups, where group 1 includes UE#1-UE#3 and group 2 includes UE#4-UE#6.

[0123] (5) Paging early indication (PEI), which is used to indicate which groups of terminal devices need to wake up and listen to the DCI scrambled by the P-RNTI.

[0124] For example, PEI uses a bitmap to indicate which group of terminal devices need to wake up and listen to the DCI scrambled by P-RNTI, see Figure 5A , Figure 5A 1 is a schematic diagram of a scenario in which a terminal device is awakened by PEI provided in an embodiment of the present application. Figure 5A As shown, if the bitmap value in PEI is 0 and 1, where the bit with a value of 1 corresponds to group 1, and the bit with a value of 0 corresponds to group 2, in this case, PEI indicates that the terminal devices belonging to group 1 need to wake up and listen to the DCI encrypted by P-RNTI, and the terminal devices belonging to group 2 do not need to wake up and listen to the DCI encrypted by P-RNTI. In other words, UE#1-UE#3 need to listen to the DCI encrypted by P-RNTI under their corresponding PO (i.e. PO1 in PF1), and UE#4-UE#6 do not need to listen to the DCI under their corresponding PO (i.e. PO1 in PF1), which can reduce the false alarm rate.

[0125] In some feasible examples, PEI can be indicated by LP WUS. For example, LP WUS carries 8 bits of information, and each bit corresponds to whether a terminal device's packet is awakened and listens to the DCI scrambled by P-RNTI. If LP WUS carries 10000001, it means awakening the packet of the first terminal device and the packet of the eighth terminal device, and listening to the DCI scrambled by P-RNTI.

[0126] See also Figure 5B , Figure 5B This is a schematic diagram of a scenario in which a terminal device is awakened by LP WUS provided in an embodiment of the present application. In addition to LP WUS, Figure 5B For information such as grouping, the number of PFs in the DRX cycle, and the number of POs in the PF, please refer to Figure 3 , Figure 4 The relevant description in will not be repeated here. Figure 5B UE#1-UE#6 associated with PO1 in PF1 are divided into two groups, where group 1 includes UE#1-UE#3 and group 2 includes UE#4-UE#6. Assume that LP WUS indicates which grouped terminal devices need to be awakened through bitmap, such as Figure 5B As shown, if the values ​​of the bitmap in LP WUS are 0 and 1. Among them, the bit with a value of 1 corresponds to group 1, and the bit with a value of 0 corresponds to group 2. In this case, LP WUS indicates that the terminal devices belonging to group 1 need to be awakened, and the terminal devices belonging to group 2 do not need to be awakened. In other words, UE#1-UE#3 need to be awakened, and then monitor the DCI encrypted by P-RNTI under their corresponding PO (i.e. PO1 in PF1), and UE#4-UE#6 do not need to monitor the DCI under their corresponding PO (i.e. PO1 in PF1), which can reduce the false alarm rate.

[0127] The current terminal device grouping methods include the terminal device identification (UE_ID based) grouping method and the core network configuration (CN assigned) grouping method. Among them, the UE_ID based grouping method is calculated by substituting the UE_ID value into the formula. The CN assigned grouping method can be specifically grouped by the AMF network element in the core network based on the paging rate of the terminal device. Figure 6 As shown, the method for configuring the paging sub-group of the terminal device on the network side may include step S601 and step S603.

[0128] S601. The AMF network element receives a registration request from a terminal device, where the registration request includes a paging rate of the terminal device.

[0129] Correspondingly, the terminal device sends a registration request to the network device. Specifically, the terminal device sends a registration request to the AMF network element.

[0130] S602. The AMF network element determines the paging sub-group of the terminal device.

[0131] Optionally, AMF groups terminal devices with similar paging rates into a group, which may be called a paging subgroup.

[0132] The AMF network element can group the terminal devices based on the paging rate reported by the terminal devices, or can group the terminal devices based on the paging rate of the terminal devices determined by itself. In other words, the paging rate reported by the terminal devices assists the network side in determining the paging sub-group of the terminal devices, and the network side can determine the paging sub-group of the terminal devices based on the paging rate reported by the terminal devices, or not based on the paging rate reported by the terminal devices. It can be understood that grouping terminal devices with similar paging rates into a paging sub-group can avoid grouping terminal devices with very different paging rates into a group, which can reduce the false alarm rate.

[0133] S603. The AMF network element sends a registration response to the terminal device, where the registration response includes an identifier of the paging sub-group of the terminal device.

[0134] Accordingly, the terminal device receives the registration response from AMF.

[0135] The identification of the paging subgroup can be represented by the identification number (ID) of the paging subgroup, and the identification of the paging subgroup can also be called the number of the paging subgroup. The present application does not limit the identification of the paging subgroup and its determination method, which can be related to the size of the paging rate, or can be related to one or more of the identification of the terminal device, the number of paging subgroups, the number of POs in the PF, the number of terminal devices corresponding to the PO, the number of PFs in a DRX cycle, etc.

[0136] Currently, the terminal device reports the paging rate at a granularity of 5%, and the paging rate can be represented by the number of bits corresponding to 5 bits. For example, please refer to Table 2, which is used to describe a corresponding relationship between the paging rate and the number of bits corresponding to the paging rate.

[0137] Table 2

[0138]

[0139] In Table 2, a gear is added for every 5% probability. For example, the paging rate corresponding to gear 0 is 0, the paging rate corresponding to gear 1 is 5%, the paging rate corresponding to gear 2 is 10%, and so on. In this example, the gears are counted from 0, and in some examples, the gears can be counted from 1. That is, the paging rate corresponding to gear 1 is 0, the paging rate corresponding to gear 2 is 5%, the paging rate corresponding to gear 3 is 10%, and so on. The description of different gears is not limited in this application, and the above different gears can also be described as the first gear, the second gear, and so on.

[0140] For the structure of paging rate, please refer to Figure 7 Schematic diagram of the Figure 7 In the example, each row represents 1 byte, and 1 byte can include 8 bits. Figure 7 As shown in the figure, the first line is used to indicate that the information is the information element identity (IEI) of LP WUS assistance information (LP WUS assistance information IEI). The second line is used to indicate the length of the paging rate (Length), which is 1, that is, 1 byte is used to represent the paging rate. The third line is used to indicate the type of the paging rate (Type) and the value corresponding to the number of bits (value).

[0141] The type of paging rate can be used to indicate the granularity of the paging rate. For example, as shown in Table 2, the granularity of the paging rate is 5%. The number of bits corresponding to the paging rate is used to indicate the number of gears of the paging rate. In this way, the paging rate can be determined based on the number of gears determined by the number of bits corresponding to the paging rate and the granularity determined by the type of the paging rate. For example, Figure 7 When the value shown is 00001, the value corresponding to 00001 is 1, and the paging rate can be equal to 1*5%, that is, 5%.

[0142] However, if Figure 4 In the mapping relationship between paging rate and energy benefit shown in FIG. 1 , when the paging rate of the terminal device is greater than 3%, the energy benefit of using LP WUS to wake up the MR is almost gone. In other words, the paging rate of the terminal device using LP WUS is likely to be no higher than 3% or a relatively low value. Reporting the paging rate of the terminal device at a granularity of 5% may cause all the terminal devices to be divided into one paging sub-group, thereby increasing the false alarm rate of the terminal device and reducing the energy benefit.

[0143] Based on this, an embodiment of the present application provides a communication method that can report a paging rate with finer granularity, which is conducive to subdividing the paging sub-groups of terminal devices and can save power consumption.

[0144] The following is based on Figure 1The system architecture shown elaborates on the communication method provided in the embodiment of the present application. Through this communication method, it is helpful to avoid unnecessary or frequent state transitions and save power consumption of terminal devices.

[0145] The following embodiments (as described below) Figure 8 or Fig.11 The terminal device in the corresponding embodiment) may be Figure 1 or Figure 2 The terminal device in the network architecture shown in the figure, the functions performed by the terminal device in this embodiment can also be performed by a device (for example, a chip, or a chip system, or a circuit) in the terminal device. The network device in the following embodiments can be Figure 1 The access network device or core network device in the network architecture shown, the function performed by the network device in this embodiment can also be performed by a device (for example, a chip, or a chip system, or a circuit) in the network device. The embodiments of this application are uniformly described here and will not be repeated later.

[0146] Optionally, the network device includes an AMF network element. Figure 8 or Fig.11 The steps performed by the network device can be performed by the AMF network element.

[0147] The following describes the communication method provided by the embodiment of the present application. Figure 8 , Figure 8 is an interactive schematic diagram of a communication method provided in an embodiment of the present application. The communication device involved in the communication method can refer to Figure 1 and Figure 2 Description of Figure 8 As shown, the communication method includes the following steps:

[0148] S101. A terminal device sends first information to a network device, where the first information includes first sub-paging information and second sub-paging information.

[0149] Correspondingly, the network device receives the first information of the terminal device.

[0150] In an embodiment of the present application, the first information may be carried in a registration request, or may be in any uplink signaling, such as uplink control information (UCI), reference signal (RS), etc. The present application does not limit the type of the first information.

[0151] S102: The network device determines a first sub-paging rate corresponding to a first granularity based on the first sub-paging information. The second sub-paging information is used to indicate a second sub-paging rate corresponding to a second granularity. The first granularity is greater than the second granularity.

[0152] In an embodiment of the present application, the first sub-paging information is used to indicate the first sub-paging rate corresponding to the first granularity, and the second sub-paging information is used to indicate the second sub-paging rate corresponding to the second granularity. The first sub-paging rate can be understood as the paging rate of the first type, and the second sub-paging rate can be understood as the paging rate of the second type. The first granularity may include the reporting granularity of the first type of paging rate, and the second granularity may include the reporting granularity of the second type of paging rate. That is, the paging rate reported according to the first type (first granularity) is the first sub-paging rate, and the paging rate reported according to the second type (second granularity) is the second sub-paging rate. When both the first sub-paging rate and the second sub-paging rate are not 0, the first sub-paging rate is an integer multiple of the first granularity, and the second sub-paging rate is an integer multiple of the second granularity.

[0153] The present application does not limit the size of the first granularity and the second granularity. For example, the first granularity is 5% and the second granularity is 0.2%. In an embodiment of the present application, the first sub-paging rate corresponding to the first granularity can also be referred to as the first sub-paging rate based on the first granularity, which can be understood as the first sub-paging rate being an integer multiple of the first granularity or 0. The second sub-paging rate corresponding to the second granularity can also be referred to as the second sub-paging rate based on the second granularity, which can be understood as the second sub-paging rate being an integer multiple of the second granularity or 0. When both the first sub-paging rate and the second sub-paging rate are not 0, A times the first granularity can be referred to as the first sub-paging rate, and B times the second granularity can be referred to as the second sub-paging rate. In other words, the first sub-paging rate is A times the first granularity, and the second sub-paging rate is B times the second granularity.

[0154] This application does not limit the size of A and B. For example, when the first granularity is 5%, A can be any integer from 1 to 20, that is, the first sub-paging rate reported by the terminal device can be 5%, 50%, 75%, 1, etc. When the second granularity is 0.2%, B can be any integer from 1 to 500, that is, the second sub-paging rate reported by the terminal device can be 0, 0.2%, 1.6%, 4.4%, 1, etc.

[0155] In the embodiment of the present application, the first sub-paging information may include the first sub-paging rate or a value associated with the first sub-paging rate, and the second sub-paging information may include the second sub-paging rate or a value associated with the second sub-paging information. The number of gears of the paging rate may be associated with the paging rate, and the value associated with the first sub-paging rate may be the number of gears of the paging rate to which the first sub-paging rate belongs or a number corresponding to the gear number, and the value associated with the second sub-paging rate may be the number of gears of the paging rate to which the second sub-paging rate belongs or a number corresponding to the gear number.

[0156] The base number may be a binary number, an octal number, a decimal number, a hexadecimal number, etc. The decimal number may be understood as the value itself. By representing the value in octal or hexadecimal, the character length is shorter than the value, which can save signaling. The bit number described in the embodiments of the present application is generally a binary number.

[0157] Optionally, the first sub-paging rate is determined by the first granularity and the number of gears of the first sub-paging rate, and the second sub-paging rate is determined by the second granularity and the number of gears of the second sub-paging rate.

[0158] The number of levels of the first sub-paging rate may be A mentioned above, and the number of levels of the second sub-paging rate may be B mentioned above.

[0159] For example, the first granularity is 5% and the second granularity is 0.2%. When the gear number A of the first sub-paging rate is 1 and the corresponding bit number is 00001 (1), the first sub-paging rate is equal to 1*5%. When the gear number B of the second sub-paging rate is 2 and the corresponding bit number is 00010 (2), the second sub-paging rate is equal to 2*0.2%.

[0160] It should be noted that in the above examples, the number of bits corresponding to the paging rate is equal to the number of gears of the paging rate. In some feasible examples, the number of bits corresponding to the paging rate may be greater than or less than the number of gears of the paging rate. For example, the number of bits corresponding to the paging rate is equal to the difference between the number of gears of the paging rate and 1, that is, the number of bits corresponding to the paging rate is less than the number of gears of the paging rate. For another example, the number of bits corresponding to the paging rate is equal to the sum of the number of gears of the paging rate and N, where N is the number of paging rates increased by the second granularity, so that the number of bits corresponding to the paging rate is greater than the number of gears of the paging rate.

[0161] In some feasible examples, the first granularity is an original granularity.

[0162] The original granularity can be understood as the granularity of the pre-configuration or original configuration of the network device, such as the aforementioned 5%. The second granularity can be understood as the increased granularity, that is, the newly configured granularity.

[0163] Exemplarily, the second granularity is 0.2%. Please refer to Table 3, which is used to describe another corresponding relationship between the paging rate and the number of bits corresponding to the paging rate.

[0164] Table 3

[0165]

[0166] In Table 3, a gear is added for every 0.2% probability. For example, the paging rate corresponding to gear 0 is 0, the paging rate corresponding to gear 1 is 0.2%, the paging rate corresponding to gear 2 is 0.4%, the paging rate corresponding to gear 24 is 4.8%, etc. In this example, the gears are counted from 0, and in some examples, the gears can be counted from 1. That is, the paging rate corresponding to gear 1 is 0, the paging rate corresponding to gear 2 is 0.2%, the paging rate corresponding to gear 3 is 0.4%, the paging rate corresponding to gear 25 is 4.8%, etc.

[0167] It should be noted that the maximum paging rate corresponding to the second granularity in Table 3 is 4.8%, which is less than the first granularity (5%). In some feasible examples, the maximum paging rate corresponding to the second granularity may be greater than the first granularity, and may even be 1.

[0168] It can be understood that when the first granularity is the original granularity, adding the second granularity is equivalent to improving the original paging rate reporting mechanism. When the first granularity is greater than the second granularity, the second sub-paging rate corresponding to the reported second granularity, that is, reporting a paging rate with finer granularity, is conducive to subdividing the paging sub-groups of the terminal device, which can reduce the probability of the terminal device being mis-paged and save power consumption.

[0169] In the embodiment of the present application, the first granularity can be understood as a coarse granularity, and the second granularity can be understood as a fine granularity. In this way, the first sub-paging rate determined by the coarse granularity and the second sub-paging rate determined by the fine granularity are reported, so that the granularity of the reported paging rate is smaller, which is conducive to subdividing the paging sub-groups of the terminal device, can reduce the probability of the terminal device being mis-paged, and save power consumption.

[0170] S103: The network device determines a first paging rate based on the first sub-paging rate and the second sub-paging rate, where the first paging rate is used to assist in determining a paging sub-group of the terminal device.

[0171] In the embodiment of the present application, the first sub-paging rate and the second sub-paging rate are used to determine the first paging rate. The present application does not limit the method for determining the first paging rate, for example, the following three determination methods.

[0172] Determination method 1: the first paging rate may be equal to the sum of the first sub-paging rate and the second sub-paging rate.

[0173] For example, the first granularity is 5% and the second granularity is 0.2%. The first sub-paging rate may be 5% and the second sub-paging rate may be 0.2%, then the first paging rate is equal to 5%+0.2%, i.e., 5.2%. The first paging rate reported by the terminal device may be at least one of 0, 0.2%, 0.4%, 0.6%, ..., 99.8% and 1, and the first paging rate may increase by one level with a probability of every 0.2%.

[0174] In an embodiment of the present application, the paging rate corresponding to the sum of the first sub-paging rate and the first granularity may be referred to as the third sub-paging rate. The gear of the third sub-paging rate is one gear higher than the first sub-paging rate. In this way, when the first paging rate is equal to the sum of the first sub-paging rate and the second sub-paging rate, the first paging rate is greater than the first sub-paging rate and less than the third sub-paging rate. In other words, the first paging rate may be reported between the first sub-paging rate and the third sub-paging rate, that is, compared with reporting the paging rate of the first granularity, a paging rate of finer granularity is reported, which is conducive to subdividing the paging sub-groups of the terminal device, can reduce the probability of the terminal device being mis-paged, and saves power consumption.

[0175] Determination method 2: when the difference between the first sub-paging rate and the second sub-paging rate is greater than 0, the first paging rate is equal to the difference; when the difference between the first sub-paging rate and the second sub-paging rate is less than 0, the first paging rate is equal to 0.

[0176] Take the first granularity of 5% and the second granularity of 1% as an example. For example, the first sub-paging rate can be 5%, and the second sub-paging rate can be 2%. Then the difference between the first sub-paging rate and the second sub-paging rate is equal to 5%-2%, that is, 3%, which is greater than 0, and the first paging rate is equal to 3%. For another example, the first sub-paging rate can be 5%, and the second sub-paging rate can be 20%. Then the difference between the first sub-paging rate and the second sub-paging rate is equal to 5%-20%, which is less than 0, and the first paging rate is equal to 0. The first paging rate reported by the terminal device can be at least one of 0, 1%, 2%, ..., 99% and 1, and the first paging rate can increase by one gear with a probability of every 1%.

[0177] It can be understood that the first paging rate is less than the first sub-paging rate when the first paging rate is equal to the difference between the first sub-paging rate and the second sub-paging rate or 0. In other words, reporting a smaller paging rate is conducive to subdividing the paging sub-groups of the terminal device, which can reduce the probability of the terminal device being mis-paged and save power consumption.

[0178] Determination method three: the first paging rate is equal to the product of the first sub-paging rate and the second sub-paging rate.

[0179] For example, the first granularity is 5% and the second granularity is 2%. The first sub-paging rate may be 5% and the second sub-paging rate may be 2%, and the first paging rate may be 5%*2%, i.e., 0.1%. The first paging rate reported by the terminal device may be at least one of 0, 0.01%, 0.02%, ..., 99.9% and 1, and the first paging rate may increase by one level with a probability of every 0.01%.

[0180] It can be understood that the second sub-paging rate is a number greater than or equal to 0 and less than or equal to 1. The value obtained by multiplying the first sub-paging rate and the second sub-paging rate must be less than or equal to the first sub-paging rate. In other words, a smaller paging rate can be reported, which is conducive to subdividing the paging sub-groups of the terminal device, can reduce the probability of the terminal device being mis-paged, and save power consumption.

[0181] It should be noted that the above three determination methods are only examples. In fact, other methods may be used to determine the first paging rate. For example, the first paging rate is equal to the product of the overall paging rate and the number of gears of the first sub-paging rate. The overall paging rate is equal to the difference between the first granularity and the second granularity.

[0182] Exemplarily, the first granularity is 5%, the second granularity is 1%, and the overall granularity is 5%-1%, that is, 4%. The first paging rate reported by the terminal device can be at least one of 0, 4%, 8%, ..., 95% and 1, and the first paging rate can increase by one gear every 4% probability. In this way, the gear of the paging rate can be reduced, so as to report a paging rate with finer granularity, which is conducive to subdividing the paging subgroups of the terminal device, can reduce the probability of the terminal device being mis-paged, and save power consumption.

[0183] For another example, the above-mentioned determination method three is adopted, but it is not limited whether the first granularity is greater than the second granularity. That is to say, the first granularity can be less than or equal to the second granularity. Exemplarily, the first granularity is 5%, and the second granularity is 10%. The first sub-paging rate can be 5%, and the second sub-paging rate can be 10%, then the first paging rate can be 5%*10%, that is, 0.5%. The first paging rate reported by the terminal device can be at least one of 0, 0.5%, 1%, ..., 99.5% and 1, and the first paging rate can increase by one gear with a probability of every 0.5%. In this way, a more fine-grained paging rate can be reported, which is conducive to the subdivision of the paging sub-groups of the terminal device, can reduce the probability of the terminal device being mis-paged, and save power consumption.

[0184] In some feasible examples, the first information also includes first subtype information and second subtype information, the first subtype information is used to indicate the first granularity, and the second subtype information is used to indicate the second granularity.

[0185] Among them, the first subtype information can be the above-mentioned first type or first granularity, or the numerical value corresponding to the first type or the numerical value corresponding to the first granularity, and the second subtype information can be the above-mentioned second type or second granularity, or the numerical value corresponding to the second type or the numerical value corresponding to the second granularity, etc. This application does not limit this.

[0186] For example, the first subtype information is a value corresponding to the first type. For example, when the first type is type1, the first subtype information may be 1 or a value corresponding to 1 (such as a binary number 001). The second subtype information is a value corresponding to the second type. For example, when the second type is type2, the first subtype information may be 2 or a value corresponding to 2 (such as a binary number 010).

[0187] For another example, the first subtype information is a value corresponding to the first granularity. For example, when the first granularity is 5%, the first subtype information may be 5 or a value corresponding to 5 (such as a binary number 101). The second subtype information is a value corresponding to the second granularity. For example, when the second granularity is 2%, the second subtype information may be 2 or a value corresponding to 2 (such as a binary number 010).

[0188] Thus, the first granularity can be determined by the first subtype information, and the second granularity can be determined by the second subtype information. Then, the first paging rate is determined according to the first granularity and the first sub-paging information, and the second paging rate is determined according to the second granularity and the second sub-paging information.

[0189] In an embodiment of the present application, the first sub-paging information and the first sub-type information may be indicated by different bytes, and the second sub-paging information and the second sub-type information may be indicated by different bytes. Or in some feasible examples, the first sub-paging information and the first sub-type information are indicated by different fields in the first byte, and the second sub-paging information and the second sub-type information are indicated by different fields in the second byte. That is, the first byte is the same byte occupied by the first sub-paging information and the first sub-type information, and the second byte is the same byte occupied by the second sub-paging information and the second sub-type information.

[0190] This application does not limit the number of fields (number of bits) occupied by the first sub-paging information and the first sub-type information, the second sub-paging information, and the second sub-type information. For example, the first sub-paging information and the second sub-paging information can occupy 5 bits, and the first sub-type information and the second sub-type information can occupy 3 bits. The number of bits corresponding to these bits is a binary number, then 5 bits can represent 32 paging rates, and 3 bits can represent 8 types of paging rates. In this way, the first sub-paging information and the first sub-type information can occupy the 8 bits of the first byte, and the second sub-paging information and the second sub-type information can occupy the 8 bits of the second byte.

[0191] For example, please refer to Fig. 9 , Fig. 9 Schematic diagram of the structure of the first paging rate provided in the embodiment of the present application. Fig. 9 In the example, each row represents 1 byte, and 1 byte can include 8 bits. Fig. 9 The first and second rows in can be referred to Figure 7 The description of Figure 7 The second line is different. Fig. 9 The length of the paging rate in the byte is 2, that is, 2 bytes are used to represent the paging rate. The third line is used to indicate the type of the first sub-paging rate and the number of bits corresponding to the first sub-paging rate, and the fourth line is used to indicate the type of the second sub-paging rate and the number of bits corresponding to the second sub-paging rate. When the first type is the type corresponding to the original granularity, the number of bits corresponding to the first sub-paging rate can be determined according to Table 2, and the number of bits corresponding to the second sub-paging rate can be determined according to Table 3. Fig. 9 As shown, the number of bits corresponding to the first sub-paging rate is 00001 (1), that is, when the first granularity is 5%, the first sub-paging rate can be 5%. The number of bits corresponding to the second sub-paging rate is 00001, that is, when the second granularity is 0.2%, the second sub-paging rate can be 0.2%.

[0192] It can be understood that the first sub-paging information and the first sub-type information are indicated by different fields of the same byte, and the second sub-paging information and the second sub-type information are indicated by different fields of another same byte, which can save signaling. And the first sub-type information and the first sub-paging information associated with the first granularity are indicated by one byte, and the second sub-type information and the second sub-paging information associated with the second granularity are indicated by another byte, which can improve the efficiency of determining the paging rate.

[0193] In some possible examples, the first byte and the second byte may be the same byte.

[0194] For example, the first sub-paging information and the second sub-paging information may occupy 2 bits, and the first sub-type information and the second sub-type information may occupy 1 bit. The number of bits corresponding to these 2 bits is an octal number, which can represent 64 paging rates. The number of bits corresponding to 1 bit is a binary number, which can represent 2 types of paging rates.

[0195] It can be understood that the first sub-paging information, the first sub-type information, the second sub-paging information and the second sub-type information are indicated by different fields of the same byte, which can further save signaling.

[0196] It should be noted that in the above example, the number of fields (bits) occupied by the first sub-paging information and the second sub-paging information are equal. In fact, the number of fields (bits) occupied by the first sub-paging information can be greater than the number of fields (bits) occupied by the second sub-paging information. For example, the first sub-paging information occupies 3 bits and the second sub-paging information occupies 2 bits.

[0197] In the embodiment of the present application, the first sub-paging information and the second sub-paging information may be indicated by different bytes. Or in other feasible examples, the first sub-paging information and the second sub-paging information are indicated by different fields in the same byte, which can save signaling.

[0198] In some other feasible examples, the first information may also include other information, which may be indicated by the first byte or the second byte. The type of information and the number of fields (bits) occupied are not limited here.

[0199] S104: The network device sends second information to the terminal device, where the second information includes an identifier of a paging sub-group of the terminal device.

[0200] Correspondingly, the terminal device receives the second information from the network device.

[0201] The second information is used to indicate the paging subgroup of the terminal device. It can be understood that the identifier of the paging subgroup of the terminal device can determine the paging subgroup of the terminal device. Optionally, before step S104, it also includes: the network device determines the identifier of the paging subgroup of the terminal device. For details, please refer to the description of step S602, which will not be repeated here.

[0202] The present application does not limit the type of the second information, and the second information may include system information, such as MIB or SIB. The second information may also be configuration information. Exemplarily, the second information includes high-layer signaling, such as RRC signaling, medium access control-control element (MAC CE) signaling, etc. The second information may also include physical layer signaling, such as DCI, etc. Optionally, the second information may be a registration response.

[0203] exist Figure 8 In the communication method shown, the terminal device sends a first message to the network device. The first message includes a first sub-paging message and a second sub-paging message, and the first sub-paging message and the second sub-paging message respectively use different granularities to represent the sub-paging rate, and the first granularity of the first sub-paging rate indicated by the first sub-paging message is greater than the second granularity of the second sub-paging rate indicated by the second sub-paging message. In this way, by reporting the second sub-paging rate, a paging rate with finer granularity can be reported. The first sub-paging rate and the second sub-paging rate can determine the first paging rate, and the first paging rate can be used to assist the network device in determining the paging sub-groups of the terminal device, which is beneficial to subdividing the paging sub-groups of the terminal device and can save power consumption.

[0204] In some feasible examples, the second sub-paging information includes first-level paging information and second-level paging information, the first-level paging information is used to indicate a first-level paging rate corresponding to the first-level granularity, and the second-level paging information is used to indicate a second-level paging rate corresponding to the second-level granularity. The first-level paging rate and the second-level paging rate are used to indicate the second sub-paging rate. The second granularity is determined by the first-level granularity and the second-level granularity, and the first-level granularity is greater than the second-level granularity.

[0205] In an embodiment of the present application, the first type may include a first subtype corresponding to the first level granularity and a second subtype corresponding to the second level granularity. The first level paging rate may be understood as the paging rate of the first subtype, and the second level paging rate may be understood as the paging rate of the second subtype. The first level granularity refers to the reporting granularity of the paging rate of the first subtype, and the second level granularity refers to the reporting granularity of the paging rate of the second subtype. That is, the paging rate reported according to the first subtype (first level granularity) is the first level paging rate, and the paging rate reported according to the second subtype (second level granularity) is the second level paging rate. When the first level paging rate and the second level paging rate are not 0, the first level paging rate is an integer multiple of the first level granularity, and the second level paging rate is an integer multiple of the second level granularity.

[0206] The present application does not limit the size of the first-level granularity and the second-level granularity, and the first-level granularity is larger than the second-level granularity. Exemplarily, the first-level granularity is 1, and the second-level granularity is 0.5%. Please refer to Table 4 and Table 5, respectively, which are used to describe another correspondence between the paging rate and the number of bits corresponding to the paging rate. The paging rate in Table 4 is the first-level paging rate, and the paging rate in Table 5 is the second-level paging rate.

[0207] Table 4

[0208]

[0209] In Table 4, a gear is added for every 1% probability. For example, the paging rate corresponding to gear 0 is 0, the paging rate corresponding to gear 1 is 1%, the paging rate corresponding to gear 3 is 3%, and the paging rate corresponding to gear 4 is 4%. In this example, the gears are counted from 0, and in some examples, the gears can be counted from 1. That is, the paging rate corresponding to gear 1 is 0, the paging rate corresponding to gear 2 is 1%, the paging rate corresponding to gear 3 is 2%, the paging rate corresponding to gear 4 is 3%, and the paging rate corresponding to gear 5 is 4%.

[0210] It should be noted that the maximum paging rate corresponding to the first level granularity in Table 4 is 4%, which is less than the first granularity (5%). In some feasible examples, the maximum paging rate corresponding to the first level granularity may be greater than the first granularity, and may even be 1. When the first level granularity is indicated by 3 bits, the first level granularity may be at most 8 times the first level granularity.

[0211] Table 5

[0212]

[0213] In Table 5, a gear is added for every 0.5% probability. For example, the paging rate corresponding to gear 0 is 0, and the paging rate corresponding to gear 1 is 0.5%. In this example, the gears are counted from 0, and in some examples, the gears can be counted from 1. That is, the paging rate corresponding to gear 1 is 0, and the paging rate corresponding to gear 2 is 0.5%.

[0214] It should be noted that the maximum paging rate corresponding to the second level granularity in Table 5 is 0.5%. In practice, it can be other values ​​less than 1.

[0215] In the embodiment of the present application, when the first-level paging rate and the second-level paging rate are not 0, C times the first-level granularity can be called the first-level paging rate, and D times the second-level granularity can be called the second-level paging rate. That is, the first-level paging rate is C times the first-level granularity, and the second-level paging rate is D times the second-level granularity.

[0216] This application does not limit the size of C and D. For example, when the first-level granularity is 1%, C can be any integer from 1 to 100, that is, the first-level paging rate reported by the terminal device can be 1%, 5%, 70%, 1, etc. When the second-level granularity is 0.5%, D can be any integer from 1 to 200, that is, the second-level paging rate reported by the terminal device can be 0.5%, 1%, 1.5%, 1, etc.

[0217] In the embodiment of the present application, the first-level paging information may be the first-level paging rate or a value associated with the first-level paging rate, and the second-level paging information may be the second-level paging rate or a value associated with the second-level paging information. The number of paging rate gears may be associated with the paging rate, and the value associated with the first-level paging rate may be the number of first-level paging rate gears or a number corresponding to the number of gears, and the value associated with the second-level paging rate may be the number of second-level paging rate gears or a number corresponding to the number of gears.

[0218] Optionally, the first-level paging rate is determined by the first-level granularity and the number of gears of the first-level paging rate, and the second-level paging rate is determined by the second-level granularity and the number of gears of the second-level paging rate.

[0219] The number of levels of the first-level paging rate may be C as mentioned above, and the number of levels of the second-level paging rate may be D as mentioned above.

[0220] For example, the first level granularity is 1%, and the second level granularity is 0.5%. The gear number C of the first level paging rate is 1, and the corresponding number of bits is 001. When the gear number D of the second sub-paging rate is 1, and the corresponding number of bits is 01, the first level paging rate is equal to 1*1%, and the second sub-paging rate is equal to 1*0.5%.

[0221] In the embodiment of the present application, the first level granularity can be understood as coarse granularity, and the second level granularity can be understood as fine granularity. In this way, the first level paging rate determined by the coarse granularity and the second level paging rate determined by the fine granularity are reported, so that the granularity of the reported paging rate is smaller, which is conducive to subdividing the paging sub-groups of the terminal device, can reduce the probability of the terminal device being mis-paged, and save power consumption.

[0222] It should be noted that the second granularity is determined by the first granularity and the second granularity, which are two levels of granularity, for example. In fact, more levels of granularity can be used to determine the second granularity, so that the terminal device can report a paging rate with finer granularity.

[0223] The present application does not limit the method for determining the second sub-paging rate, for example, the following three determination methods.

[0224] Determination method A, the second sub-paging rate may be equal to the sum of the first level paging rate and the second level paging rate.

[0225] Optionally, the second granularity is equal to the sum of the first granularity and the second granularity.

[0226] Exemplarily, the first level granularity is 1%, the second level granularity is 0.5%, and the second granularity is equal to 1+0.5%, i.e., 1.5%. The first level paging rate may be 1%, and the second level paging rate may be 0.5%, then the first level paging rate is equal to 1%+0.5%, i.e., 1.5%. The terminal device may report the first level paging rate with reference to Table 4, and the terminal device may report the second level paging rate with reference to Table 5. The second sub-paging rate reported by the terminal device may be at least one of 0, 0.5%, 1, ..., 99.5% and 1, and the second sub-paging rate may increase by one level with a probability of every 0.5%.

[0227] In an embodiment of the present application, the paging rate corresponding to the sum of the first-level paging rate and the first-level granularity can be called the third-level paging rate. The gear of the third-level paging rate is one gear higher than the first-level paging rate. In this way, when the second sub-paging rate is equal to the sum of the first-level paging rate and the second-level paging rate, the second sub-paging rate is greater than the first-level paging rate and less than the third-level paging rate. In other words, the second paging rate can be reported between the first-level paging rate and the third-level paging rate, that is, a paging rate with finer granularity is reported compared to the paging rate reported at the first-level granularity, which is conducive to subdividing the paging sub-groups of the terminal device, can further reduce the probability of the terminal device being mis-paged, and save power consumption.

[0228] Determination method B: when the difference between the first-level paging rate and the second-level paging rate is greater than 0, the second sub-paging rate is equal to the difference; when the difference between the first-level paging rate and the second-level paging rate is less than 0, the second sub-paging rate is equal to 0.

[0229] Optionally, the second granularity is equal to the difference between the first granularity and the second granularity or 0.

[0230] Taking the first-level granularity of 1% and the second-level granularity of 0.5% as an example, the second granularity can be equal to 1%-0.5%, that is, 0.5%. For example, the first-level paging rate can be 4%, and the second-level paging rate can be 0.5%. The difference between the first-level paging rate and the second-level paging rate is equal to 4%-0.5%, that is, 3.5%, which is greater than 0, and the second sub-paging rate is equal to 3.5%. For another example, the first-level paging rate can be 0%, and the second-level paging rate can be 0.5%. The difference between the first sub-paging rate and the second sub-paging rate is equal to 0%-0.4%, which is less than 0, and the second sub-paging rate is equal to 0. The second sub-paging rate reported by the terminal device can be at least one of 0, 0.5%, 1%, ..., 99.5% and 1, and the second sub-paging rate can increase by one level with a probability of every 0.5%.

[0231] It can be understood that when the second sub-paging rate is equal to the difference between the first-level paging rate and the second-level paging rate or 0, the second sub-paging rate is less than the first-level paging rate. In other words, reporting a smaller paging rate is conducive to subdividing the paging sub-groups of the terminal device, which can reduce the probability of the terminal device being mis-paged and save power consumption.

[0232] Determination method C: the second sub-paging rate is equal to the product of the first-level paging rate and the second-level paging rate.

[0233] Optionally, the second granularity is equal to the product of the first level granularity and the second level granularity.

[0234] For example, the first level granularity is 1%, the second level granularity is 0.5%, and the second granularity can be equal to 1%*0.5%, that is, 0.005%. The first level paging rate can be 1%, the second level paging rate can be 0.5%, and the second sub-paging rate can be 0.005%. The second sub-paging rate reported by the terminal device can be at least one of 0, 0.005%, 0.01%, ..., 99.995% and 1, and the second sub-paging rate can increase by one level with a probability of every 0.005%.

[0235] It can be understood that the second-level paging rate is a number greater than or equal to 0 and less than or equal to 1. The value obtained by multiplying the first-level paging rate and the second-level paging rate must be less than or equal to the second sub-paging rate. In other words, a smaller paging rate can be reported, which is conducive to subdividing the paging sub-groups of the terminal device, can reduce the probability of the terminal device being mis-paged, and save power consumption.

[0236] It should be noted that the above three determination methods are only examples. In fact, other methods may be used to determine the second sub-paging rate. For example, the second sub-paging rate is equal to the product of the second granularity and the number of gears of the first-level paging rate. The second granularity is equal to the difference between the first-level granularity and the second-level granularity.

[0237] Exemplarily, the first level granularity is 1%, the second level granularity is 0.5%, and the second granularity is 0.5%. The second sub-paging rate reported by the terminal device can be at least one of 0, 0.5%, 1%, ..., 99.5% and 1, and the second sub-paging rate can increase by one level with a probability of every 0.5%. In this way, the level of the paging rate can be reduced, so as to report a paging rate with finer granularity, which is conducive to subdividing the paging sub-groups of the terminal device, can reduce the probability of the terminal device being mis-paged, and save power consumption.

[0238] For another example, the above-mentioned determination method C is adopted, but it is not limited whether the first-level granularity is greater than the second-level granularity. In other words, the first-level granularity can be less than or equal to the second-level granularity. Exemplarily, the first-level granularity is 1%, and the second-level granularity is 5%. The first-level paging rate can be 5%, the second-level paging rate can be 10%, and the second sub-paging rate can be 5%*10%, that is, 0.5%. The second sub-paging rate reported by the terminal device can be at least one of 0, 0.5%, 1%, ..., 99.5% and 1, and the second sub-paging rate can increase by one gear with a probability of every 0.5%. In this way, a paging rate with finer granularity can be reported, which is conducive to the subdivision of the paging sub-groups of the terminal device, can reduce the probability of the terminal device being mis-paged, and save power consumption.

[0239] This application does not limit the number of fields (number of bits) occupied by the first-level paging information and the second-level paging information, because the first-level granularity is greater than the second-level granularity, and the number of fields occupied by the first-level paging information is greater than or equal to the number of fields occupied by the second-level paging information. Exemplarily, when the second sub-paging information occupies 5 bits, the first-level paging information can occupy 3 bits and the second-level paging information can occupy 2 bits.

[0240] Please refer to Fig.10 , Fig.10 Schematic diagram of the structure of the second paging rate provided in the embodiment of the present application. Fig.10 In the example, each row represents 1 byte, and 1 byte can include 8 bits. Fig.10 The first, second, third and fourth rows in the Fig. 9 The description of Fig. 9 The fourth line of Fig.10 The second sub-paging rate is determined by the first-level paging rate and the second-level paging rate. The number of bits corresponding to the first-level paging rate can be determined according to Table 4, and the number of bits corresponding to the second-level paging rate can be determined according to Table 5. Fig.10 As shown, the number of bits corresponding to the first-level paging rate is 001 (1), that is, when the first-level granularity is 1%, the first-level paging rate can be 1*1%. The number of bits corresponding to the second-level paging rate is 01 (1), that is, when the second-level granularity is 0.5%, the second-level paging rate can be 1*0.5%. The second granularity can be equal to 1%+0.5%, that is, 1.5%. The second sub-paging rate can also be equal to 1.5%. The number of bits corresponding to the first sub-paging rate is 00000 (0), that is, the first sub-paging rate is 0. The first paging rate can be equal to 0+1.5%, that is, 1.5%.

[0241] It can be understood that the first-level paging information and the second-level paging information are indicated by different fields of the same byte, which can save signaling.

[0242] Please refer to Fig.11 , Fig.11 is an interactive schematic diagram of another communication method provided in an embodiment of the present application. The communication device involved in the communication method can refer to Figure 1 and Figure 2 The description of is not repeated here. Fig.11 As shown, the communication method may include the following steps:

[0243] S201. The terminal device sends first information to the network device.

[0244] Correspondingly, the network device receives the first information of the terminal device.

[0245] In the embodiment of the present application, the first information is used to indicate the first paging rate or the second paging rate. The type of the first information can refer to Figure 8 The description will not be repeated here.

[0246] S202. The network device determines a first paging rate or a second paging rate based on the first information, the second paging rate corresponds to a first granularity, the first paging rate corresponds to a second granularity, the first granularity is greater than the second granularity, and the first paging rate or the second paging rate is used to assist in determining a paging subgroup of the terminal device.

[0247] The first particle size and the second particle size can refer to Figure 8 The description will not be repeated here.

[0248] In some feasible examples, the first granularity is an original granularity.

[0249] In this way, the second paging rate is reported based on the original granularity, or the first granularity is reported based on the newly configured granularity. If the first granularity is greater than the second granularity, the original granularity is finer than the newly configured granularity, so a finer granularity paging rate is used when reporting the first paging rate, which is conducive to subdividing the paging subgroups of the terminal device, can reduce the probability of the terminal device being mis-paged, and save power consumption.

[0250] In the embodiment of the present application, the second paging rate corresponds to the first granularity, and the first granularity may correspond to multiple second paging rates. The first paging rate corresponds to the second granularity, and the second granularity may correspond to multiple first paging rates. What is reported in S201 is one first paging rate or one second paging rate.

[0251] The second paging rate corresponding to the first granularity can also be called the (second) paging rate based on the first granularity, and the second paging rate can be an integer multiple of the first granularity or 0. The first paging rate corresponding to the second granularity can also be called the (first) paging rate based on the second granularity, and the first paging rate can be an integer multiple of the second granularity or 0. When the first paging rate and the second paging rate are not 0, E times the first granularity can be called the second paging rate, and F times the second granularity can be called the first paging rate. That is, the second paging rate is E times the first granularity, and the first paging rate is F times the second granularity.

[0252] This application does not limit the size of E and F. For example, when the first granularity is 5%, E can be any integer from 1 to 20, that is, the second paging rate reported by the terminal device can be 5%, 50%, 75%, 1, etc. When the second granularity is 0.5%, F can be any integer from 1 to 200, that is, the first paging rate reported by the terminal device can be 0.5%, 1.0%, 4.5%, 1, etc.

[0253] In the embodiment of the present application, the first paging rate can be understood as the third type of paging rate, and the second paging rate can be understood as the fourth type of paging rate. The fourth type can be understood as the original coarse-grained type, and the third type can be understood as the type corresponding to the first type of the first sub-paging rate and the second type of the second sub-paging rate, that is, a new type of subdivided granularity.

[0254] The first granularity may include the reporting granularity of the fourth type of paging rate, and the second granularity may include the reporting granularity of the third type of paging rate. That is, the paging rate reported according to the fourth type (first granularity) is the second paging rate, and the paging rate reported according to the third type (second granularity) is the first paging rate.

[0255] Optionally, the first paging rate belongs to a first paging rate group, and the second paging rate belongs to a second paging rate group.

[0256] Among them, any paging rate in the second paging rate group is an integer multiple of the first granularity or 0, and any paging rate in the first paging rate group is an integer multiple of the second granularity or 0. That is, the (first) paging rates corresponding to the second granularity can be grouped into a group and called the first paging rate group. The (second) paging rates corresponding to the first granularity can also be grouped into a group and called the second paging rate group.

[0257] In an embodiment of the present application, the multiple second paging rates corresponding to the first granularity and the multiple first paging rates corresponding to the second granularity may include different paging rates, or may include the same paging rate. That is, the second paging rate group corresponding to the first granularity and the first paging rate group corresponding to the second granularity may include different paging rates, or may include the same paging rate. For example, in some feasible examples, the multiple second paging rates corresponding to the first granularity include the maximum paging rate and the minimum paging rate among the multiple first paging rates corresponding to the second granularity. That is, the first paging rate group includes 2 paging rates in the second paging rate group, one as the maximum paging rate of the first paging rate group, and the other as the minimum paging rate of the first paging rate group.

[0258] Exemplarily, please refer to Table 6, which is used to describe another corresponding relationship between the paging rate and the number of bits corresponding to the paging rate.

[0259] Table 6

[0260]

[0261] In Table 6, the first granularity can be 5%, and the second granularity can be 0.5%. The multiple first paging rates corresponding to the second granularity include 0, 0.5%, 1.0% to 5.0%, a total of 11 values. The multiple second paging rates corresponding to the first granularity include 0, 5.0%, 10% to 100%, a total of 21 values. The minimum paging rate 0 in the first paging rate and the maximum paging rate 5.0% in the first paging rate belong to both the first paging rate group and the second paging rate group. The first paging rate increases by one gear for every 0.5% probability, and the second paging rate increases by one gear for every 5% probability.

[0262] In some feasible examples, the first information includes first paging information, and the first paging information is used to indicate the first paging rate or the second paging rate.

[0263] When the first paging information indicates the first paging rate, the first paging rate or a numerical value associated with the first paging rate may be included. When the first paging information indicates the second paging rate, the second paging rate or a numerical value associated with the second paging rate may be included. The number of gears of the paging rate may be associated with the paging rate, and the numerical value associated with the first paging rate may be the number of gears of the first paging rate or a base number corresponding to the number of gears, and the numerical value associated with the second paging rate may be the number of gears of the second paging rate or a base number corresponding to the number of gears. The number of gears of the second paging rate may be the above-mentioned E, and the number of gears of the first paging rate may be the above-mentioned F. The base number is indicated by the bits in the byte, and may also be called the bit number.

[0264] In some feasible examples, the first information includes a first number of bits or a second number of bits; the first paging rate is determined by the first number of bits and the second granularity, and the second paging rate is determined by the second number of bits, the second granularity, and the first granularity.

[0265] The first information in this example may be the first paging information, that is, the first paging information includes the first number of bits or the second number of bits. The first number of bits may be the number of gears corresponding to the first paging rate, and the second number of bits may be the number of gears corresponding to the second paging rate. This scheme is to subdivide the paging rate, the second granularity is smaller than the first granularity, the first paging rate may be specifically located between the first gear and the second gear in the second paging rate, and the number of gears corresponding to the first paging rate may be equal to the value corresponding to the first number of bits. Due to the increase in the first paging rate, the value corresponding to the second number of bits will increase, and the number of increased paging rates (excluding the repeated paging rates in the first paging rate and the second paging rate) is related to the second granularity, and the number of gears of the second paging rate may be equal to the difference between the value corresponding to the second number of bits and the number of increased paging rates. After obtaining the number of gears of the first paging rate and the number of gears of the second paging rate, the first paging rate may be determined according to the product of the number of gears of the first paging rate and the second granularity, and the second paging rate may be determined according to the product of the number of gears of the second paging rate and the first granularity.

[0266] Exemplarily, the first granularity is 5% and the second granularity is 0.5%. Referring to Table 6, when the first bit number is 00010 (2), the number of gears of the first paging rate is 2, and the first paging rate is equal to 2*0.5%, that is, 1.0%. When the second bit number is 01011 (11), the number of first paging rates corresponding to the second granularity is 11, and the number of repeated paging rates in the first paging rate and the second paging rate is 2, that is, the number of increased paging rates is 11-2, that is, 9. The number of gears of the second paging rate is 11-9, that is, 2. The second paging rate is equal to 2*5%, that is, 10%.

[0267] It should be noted that in the above example, the first bit number is equal to the gear number of the first paging rate. In some feasible examples, when the gear number starts counting from 1, the first bit number may be equal to the difference between the gear number of the first paging rate and 1. The second bit number is equal to the sum of the number of increased paging rates and the gear number of the second paging rate. In some feasible examples, when the gear number starts counting from 1, the second bit number may be equal to the difference between the sum of the number of increased paging rates and the gear number of the second paging rate and 1.

[0268] In some feasible examples, the first information includes first type information; when the first information is used to indicate the first paging rate, the first type information is used to indicate the second granularity; when the first information is used to indicate the second paging rate, the first type information is used to indicate the first granularity.

[0269] That is, the first type of information determines whether the report is based on the first granularity or the second granularity, and then the first paging rate or the second paging rate can be determined according to the reported first paging information. The method for determining the first paging rate or the second paging rate can refer to the description of the previous example, which will not be repeated here.

[0270] For example, please refer to Fig. 12A , Fig. 12A Schematic diagram of the structure of the third paging rate provided in the embodiment of the present application. Fig. 12A In the example, each row represents 1 byte, and 1 byte can include 8 bits. Fig. 12A The first, second, and third rows in Figure 7 The description of Figure 7 The third line of Fig. 12A The type of paging rate in the medium may indicate the first granularity or the second granularity. The number of bits corresponding to the second paging rate corresponding to the first granularity and the number of bits corresponding to the first paging rate corresponding to the second granularity may refer to Table 6. Fig. 12A As shown, when the first type information is used to indicate the first paging rate, the first type information indicates the second granularity through 010, and the number of bits corresponding to the first paging rate is 00101 (5). When the second granularity is 0.5%, the first paging rate can be 5*0.5%, that is, 2.5%.

[0271] Alternatively, in some other feasible examples, the first information includes first type information, and the first type information is used to indicate the fourth type. The fourth type is the original type as mentioned above, and can refer to Figure 7 The type of the paging rate is shown. In this way, the type of the original structure description is not modified.

[0272] For example, please refer to Fig. 12B , Fig. 12BSchematic diagram of the structure of the fourth paging rate provided in the embodiment of the present application. Fig. 12B In the example, each row represents 1 byte, and 1 byte can include 8 bits. Fig. 12B The first, second, and third rows in Figure 7 The description of Figure 7 and Fig. 12A The third line of Fig. 12B The type of the paging rate in is the original type, that is, it indicates the first granularity. Fig. 12B As shown, the first type of information is indicated by 001, and the first paging information is indicated by the number of bits 00101 (5). According to Table 6, the first paging rate may be 2.5%.

[0273] In some feasible examples, the first paging rate and the second paging rate each occupy M bits, the difference between the number of paging rates corresponding to the second granularity and the number of repeated paging rates is less than or equal to a first value, and the first value is equal to the difference between the total number of paging rates corresponding to M and the number of paging rates corresponding to the first granularity.

[0274] Among them, the repeated paging rate is the paging rate repeated in the paging rate corresponding to the first granularity and the paging rate corresponding to the second granularity. The difference between the number of paging rates corresponding to the second granularity and the number of repeated paging rates can be understood as the number of refined paging rates. In the case where the first granularity is the original granularity, the difference between the number of paging rates corresponding to the second granularity and the number of repeated paging rates can be understood as the number of newly added paging rates. The total number of paging rates corresponding to M refers to the maximum value of the paging rate that can be represented by M bits. For example, when M is 5, the total number of paging rates corresponding to M can be 2 to the power of 5, that is, 32.

[0275] Take M as 5, and the total number of paging rates corresponding to M as 32 for example. Referring to Table 6, when the first granularity is 5% and the second granularity is 0.5%, the number of paging rates corresponding to the first granularity is 21, the number of paging rates corresponding to the second granularity is 11, and the number of repeated paging rates is 2. The first value is equal to 32-21, that is, 11. The difference between the number of paging rates corresponding to the second granularity and the number of repeated paging rates is equal to 11-2, that is, 9<11. In this way, the number of the first paging rate of the refined granularity is increased without deleting the second paging rate, and without modifying the number of bits occupied by the paging rate.

[0276] In an embodiment of the present application, the first paging information and the first type of information may be indicated by different bytes. Or in some feasible examples, the first paging information and the first type of information are indicated by different fields of the third byte. That is, the third byte is the same byte occupied by the first paging information and the first type of information. It can be understood that the first paging information and the first type of information are indicated by different fields of the same byte, which can save signaling. And the first type of information and the first paging information correspond to the same granularity, which can improve the efficiency of determining the paging rate.

[0277] This application does not limit the number of fields (bits) occupied by the first paging information and the first type of information. Fig. 12A and Fig. 12B As shown, the first paging information can occupy 5 bits, and the first type information can occupy 3 bits. The bit numbers corresponding to these bits are binary numbers, so 5 bits can represent 32 paging rates, and 3 bits can represent 8 types of paging rates. In this way, the first paging information and the first type information can occupy the 8 bits of the first byte.

[0278] Alternatively, in some other feasible examples, the first information does not include the first type of information. When the terminal device does not directly report the first paging rate or the second paging rate, the first paging rate or the second paging rate is determined according to the base number (byte number or bit number) reported by the terminal device and a preset table (such as Table 6).

[0279] S203: The network device sends second information to the terminal device, where the second information includes an identifier of a paging sub-group of the terminal device.

[0280] Correspondingly, the terminal device receives the second information from the network device.

[0281] The second information can refer to Figure 8 The description will not be repeated here.

[0282] exist Fig.11 In the communication method shown, the terminal device sends first information to the network device. The first information is used to indicate a first paging rate corresponding to a first granularity or a second paging rate corresponding to a second granularity, and the first granularity is greater than the second granularity. In this way, a first paging rate with finer granularity can be reported. The first paging rate can be used to assist in determining the paging subgroups of the terminal device, which is beneficial for subdividing the paging subgroups of the terminal device and can save power consumption.

[0283] It should be noted that, in the above examples, the first granularity and the second granularity can be used as a numerical value or a numerical value of a level. In fact, the second granularity can be determined by the numerical values ​​of the first level granularity and the second level granularity, which are two levels of granularity, as described above, or the first granularity and the second granularity can be determined by numerical values ​​of more granularity levels, so that the terminal device can report a paging rate with finer granularity.

[0284] The method of the embodiment of the present application is described in detail above, and the device of the embodiment of the present application is described below.

[0285] See also Fig.13 , Fig.13 It is a structural diagram of a communication device provided in an embodiment of the present application. The communication device may include a transceiver unit 101 and a processing unit 102. Among them, the transceiver unit 101 may be a device with a signal input (receiving) or output (sending), used to transmit signals with other devices or other devices in the device. The processing unit 102 may be a device with a processing function, and may include one or more processors for executing instructions (or codes or programs), for example, processing communication protocols and communication data. The communication device may be a terminal device, or a device in a terminal device (for example, a chip, or a chip system, or a circuit, etc.), or a device that can be used in combination with a terminal device. The communication device may be a network device, or a device in a network device (for example, a chip, or a chip system, or a circuit, etc.), or a device that can be used in combination with a network device.
