Figure 1Taking the communication system 100 shown as an example, the communication equipment may include a network device 110 and a terminal device 120 with communication functions.

[0043] For ease of understanding, some relevant technical knowledge involved in the embodiments of this application is first introduced. The following related technologies can be combined with the technical solutions of the embodiments of this application as optional solutions, and they all fall within the scope of protection of the embodiments of this application. The embodiments of this application include at least part of the following contents.
[0044] With the advancement of mobile communication technology, next-generation wireless evolution systems (e.g., 5G systems) are using a variety of technologies to increase data transmission rates to meet the demands of transmitting large amounts of data, such as high-definition video and virtual reality. These technologies include massive multiple-input multiple-output (MIMO), non-orthogonal multiple access (NMA), simultaneous full-duplex communication (SCHF), novel modulation techniques, novel coding techniques, and high-order modulation techniques. These technologies enable peak data rates up to Gbit / s.
[0045] For example, air interface latency needs to be around 1ms to support real-time applications such as autonomous driving and telemedicine. Ultra-large network capacity can connect hundreds of billions of devices, meeting the communication needs of the Internet of Things. For example, the spectrum efficiency of NR systems is over 10 times higher than that of LTE systems. Thanks to its continuous wide-area coverage and high mobility, users can experience data rates up to 100 Mbit / s. This significantly increases traffic density and connection density.
[0046] Furthermore, improvements in system collaboration and intelligence further enhance network flexibility. This collaboration can be manifested in collaborative networking with multiple users, multiple points, multiple antennas, and multiple sources. This collaboration and intelligence enable flexible and automatic adjustments between networks.
[0047] However, in a communication system, the power consumption of network devices (e.g., base stations) is usually relatively high. In order to save the power consumption of network devices, it is necessary to optimize the processing of system messages. For example, network devices usually periodically send SIB1 for initial access and schedule other SIBs for terminal devices in idle / inactive mode. However, even if there is no demand from the terminal device or no terminal device is resident on the cell, the network device will always transmit, resulting in a large amount of power consumption. For this reason, in order to save network energy, the 3rd Generation Partnership Project (3GPP) conducted a lot of research on on-demand SIB1 for terminal devices in idle / inactive mode in release 18 (R18) and R19, so as to achieve network energy saving by reducing unnecessary SIB1 transmission and associated physical random access channel (PRACH) monitoring.
[0048] In some communication systems, the NES function is introduced based on the need for network energy conservation. In a cell that supports NES configuration, network equipment can send SSBs with variable periods and / or send SIB1 on demand. However, the terminal devices in the cell may or may not support the NES function. Therefore, due to the emergence of NES cells, terminal devices may include traditional terminal devices and terminal devices that support NES configuration. Among them, traditional terminal devices can also be called legacy terminal devices, and terminal devices that support NES configuration can also be called NES terminal devices.
[0049] The design of the paging mechanism within NES-enabled cells requires further study. When the network needs to connect to a terminal device, it initiates a paging process to send a paging message to the terminal device. Terminal devices in idle mode, while in a discontinuous reception (DRX) cycle or an extended DRX (eDRX) cycle, can periodically wake up to detect paging messages.
[0050] In some scenarios, when SIB1 within a cell is transmitted on demand, it is necessary to consider how to transmit paging-related configurations or parameters in the SIB1. In other words, how to modify the paging mechanism to support on-demand SIB1 transmission is a research direction. Furthermore, how to adjust the relevant paging mechanism based on existing technologies to achieve better energy conservation is also a technical difficulty that needs to be studied.
[0051] In some scenarios, traditional terminal devices require the network equipment to periodically send SIBs, but terminal devices that support NES configuration do not. The paging mechanism needs to be flexibly configured based on the different types of terminal devices within the cell. When the paging mechanism considers the detection needs of both traditional and NES terminal devices, it helps save energy. Therefore, improving the paging mechanism to be compatible with traditional and NES terminal devices, thereby saving terminal device energy consumption, has become a research goal.
[0052] In some scenarios, it is also necessary to consider how cells supporting NES configuration send paging messages to increase the cell's sleep time.
[0053] In summary, in a cell supporting NES configuration, how to design a paging mechanism to save energy becomes a problem that needs to be solved.
[0054] It should be noted that the above-mentioned problem that the paging mechanism needs to be compatible with two types of terminal devices due to the differences between traditional terminal devices and NES terminal devices is only an example. The embodiments of the present application can be applied to communication scenarios where the paging mechanism needs to be compatible with any number of types of terminal devices.
[0055] In response to the above problems, an embodiment of the present application proposes a method for wireless communication. Through this method, the terminal device can determine one or more POs that need to be detected within the first period based on the first information. When the first information is related to the type of terminal device, PO or PEI, different terminal devices can determine the PO corresponding to it. After the first information indicates that the PF is set continuously, the network device and the terminal device can perform centralized paging and detection within the continuous PF, thereby achieving effective energy saving. For ease of understanding, the following is combined with Figure 2 The method proposed in the embodiment of the present application is described in detail. Figure 2 The method shown is executed by a terminal device.
[0056] See also Figure 2 In step S210, the terminal device determines one or more POs corresponding to the terminal device within the first period according to the first information.
[0057] The terminal device may be in different states, which is not limited here. As an example, the terminal device may be in an idle state or an inactive state, and needs to detect whether there is a corresponding paging message within the first cycle. As an example, the terminal device may be in an active state or a radio resource control (RRC) connected state, and may determine the wake-up time and PF / PO before entering the idle state to facilitate timely reception of PEI or paging messages.
[0058] In some embodiments, the terminal device may be a communication device supporting NES configuration, or a communication device having NES functionality. In other words, the terminal device may be the NES terminal device described above.
[0059] In some embodiments, the terminal device may be a traditional terminal device, which may also be referred to as a legacy terminal device.
[0060] The serving cell corresponding to the terminal device is the first cell. The terminal device can connect to the network device of the first cell. In other words, the cell where the first terminal device is located is the first cell, or the network device corresponding to the first cell can provide services to the terminal device.
[0061] In some embodiments, the first cell may be a cell where energy conservation is required on the network side. The cell may be any of the cells described above. The energy conservation required on the network side may include energy conservation of network equipment or energy conservation of the core network. Optionally, the first cell may be an NES cell or a network energy conservation cell with similar functionality.
[0062] As an example, for a terminal device in idle / inactive mode, the first cell to send SIB1 on demand is the NES cell.
[0063] The network device may be any of the access network devices described above, or may be a core network device. In some embodiments, the network device may be a communication device that sends a paging message to a terminal device. The terminal device may receive the paging message sent by the network device.
[0064] In some embodiments, when a paging message corresponding to a terminal device arrives, the network device may determine the PO corresponding to the terminal device based on the terminal device's identity (ID) to send the paging message. The terminal device also needs to determine one or more corresponding POs and detect the paging message on these one or more POs to reduce unnecessary energy consumption.
[0065] For example, a paging opportunity (PO) is generally a monitoring opportunity of a physical downlink control channel (PDCCH), which is composed of multiple time slots, and therefore may also be called a paging opportunity.
[0066] For example, one PO may include S synchronization signal block (SSB) beams, where S may be determined by ssb-PositionsInBurst in the SIB1 message. The paging message sent on each SSB beam may be exactly the same.
[0067] As an example, the network device may send a paging message of the terminal device on a corresponding PO by broadcasting. The terminal device may detect on the corresponding PO to determine whether there is its own paging message.
[0068] As an example, after determining one or more POs that need to be detected, the terminal device can detect the paging message on the one or more POs. In other words, the one or more POs are used for the terminal device to perform paging detection.
[0069] The one or more POs determined by the terminal device are the POs corresponding to the terminal device. When the terminal device receives a paging message, the network device will send the paging message to the PO corresponding to the terminal device so that the terminal device can receive it. Therefore, the one or more POs corresponding to the terminal device can also be replaced with the one or more POs that the terminal device needs to detect.
[0070] In some embodiments, the terminal device determines one or more POs, which means that the terminal device determines the time domain location and / or frequency domain location of the one or more POs. As an example, the frame in which the one or more POs are located can be called a PF. The time domain location of the one or more POs can be determined by the location parameters of the PF.
[0071] As an example, a PF can be composed of multiple POs. For example, there are Ns POs in one PF.
[0072] As an example, the location of the PO may be replaced by the location of the PF. The terminal device may determine the location of the PO after determining the location of the PF.
[0073] In some embodiments, one or more POs corresponding to the terminal device may be located in one PF or multiple PFs. The multiple PFs may be multiple PFs within one cycle or multiple PFs within multiple cycles, which is not limited here.
[0074] As an example, the PF where one or more POs corresponding to the terminal device are located will also be paged and detected by the terminal device. Therefore, the one or more POs corresponding to the terminal device can be replaced by one or more PFs corresponding to the terminal device.
[0075] The terminal device needs to determine one or more POs corresponding to it within the first cycle. In some embodiments, the first cycle can be any one or more cycles related to energy saving. If there are no POs to be detected within the first cycle, the terminal device can remain in a dormant state to save energy. For example, the first cycle can be one or more DRX cycles of the terminal device. For another example, the first cycle can be one or more eDRX cycles. In some embodiments, the first cycle can be one or more paging cycles to facilitate the terminal device to periodically detect paging messages.
[0076] As an example, the first cycle may be a DRX cycle. After determining one or more POs corresponding to the DXR cycle, the terminal device may wake up before the PO to detect the paging message in the PO.
[0077] As an example, the first cycle may be multiple DRX cycles. The terminal device may better detect the paging message in an idle state or inactive mode according to one or more POs corresponding to the multiple DRX cycles.
[0078] As an example, the first cycle may be a paging cycle. The paging cycle may be a default paging cycle configured by a higher layer, or a specific DRX cycle of the terminal device. For example, the paging cycle T = min (default paging cycle, UE-specific DRX cycle).
[0079] As an example, the first cycle may be multiple default paging cycles.
[0080] As an example, the first period may include one PF or a specified number of multiple PFs.
[0081] As an example, the first period may be a specified time period, which may be a time period based on NES function configuration or similar function configuration.
[0082] As an example, the first period may be any time period configured by a higher layer, which is not limited here.
[0083] In some embodiments, the position of one or more POs corresponding to the terminal device in the first period can be determined based on the configuration parameters of the first period and the ID of the terminal device (UE ID ) is determined. For example, the position of the PO corresponding to any UE in the PF can be i s =floor(UE ID / N)mod N s .
[0084] As an example, for an NES terminal device, the position of the corresponding PO in the first cycle or any PF within the first cycle can be represented as is,NES .
[0085] As an example, the position of the PO in the first cycle can be represented as the position of the PO in the PF. The position can be represented by an index value.
[0086] As an example, the position i of PO in the first cycle s,NES It can indicate the starting position of a set of PDCCH monitoring opportunities. The NES terminal device can start from the i s,NES Each PO starts to receive paging messages continuously.
[0087] The terminal device may determine one or more POs corresponding to it within the first period based on the first information. In some embodiments, the terminal device may determine the first information in a variety of ways. For example, the first information may come from the network device. In another example, the first information may be information of the terminal device itself. In another example, the first information may be determined based on the PEI or other similar indication information received by the network device. In another example, the first information may be determined based on higher-layer configuration information.
[0088] In some embodiments, the first information may be carried in one or more of the following information: SIB, RRC, and downlink control information (DCI).
[0089] In some embodiments, the first information may include one or more of the following: the type of PO within the first period; the type of terminal device; the type of PEI received by the terminal device / the type of PEI sent by the network device to the terminal device; and whether the PF within the first period is continuous. In other words, the terminal device may determine one or more corresponding POs based on any one or a combination of any two or more of these information.
[0090] It should be noted that the terminal device can determine one or more POs corresponding to it based on a combination of the first information and any other information, and the any information is not limited.
[0091] The following is an illustrative description of a method for a terminal device to determine a corresponding PO based on the first information in conjunction with multiple embodiments.
[0092] Example 1
[0093] The first information may include the type of PO within the first period and / or the type of terminal device. The PO within the first period may include at least two types of PO. The at least two types of PO may be used to send at least two types of paging messages or perform paging actions on at least two types of terminal devices, respectively. That is, the time-frequency resources (PO) used by the network side to send paging messages may be divided into at least two groups.
[0094] In some embodiments, the at least two types of POs may include traditional POs, POs supporting NES configurations, and POs related to other energy-saving configurations, which are not limited here.
[0095] In some embodiments, at least two types of POs may correspond to at least two types of terminal devices, or may correspond to at least two types of application scenarios. The terminal device may perform paging detection on the corresponding type of PO based on its own type or the application scenario in which it is located. For the sake of simplicity, the following description is based on an example in which the POs in the first cycle include two types of POs.
[0096] As an example, the POs within the first cycle may include first-category POs and second-category POs. First-category POs correspond to first-category terminal devices without NES functionality, while second-category POs correspond to second-category terminal devices with NES functionality. For example, first-category POs are used to send paging messages to traditional terminal devices, while second-category POs are used to send paging messages to NES terminal devices. In other words, when a terminal device is a traditional terminal device, the corresponding one or more POs are POs in the first category; when a terminal device has NES functionality, the corresponding one or more POs are POs in the second category.
[0097] As an example, the first type of PO is a traditional PO, and the second type of PO is an NES PO. When the terminal device is a traditional terminal device, paging detection can be performed on the traditional PO. When the terminal device is an NES terminal device, paging detection can be performed on the NES PO.
[0098] In some embodiments, the positions of the first and second category POs within the first period can be determined separately. For example, the positions of the first category POs can be determined based on a relevant calculation formula, while the positions of the second category POs are specified by the system through network devices or higher layers.
[0099] As an example, the system may identify a specific system frame number (SFN) for a specific type of terminal device. For example, the system may identify a specific SFN for an NES terminal device and allocate multiple PFs for the NES terminal device consecutively or at regular intervals.
[0100] As an example, the system may consider configuring / indicating the starting offset of each second type PO for each PF independently. For example, the system may indicate the starting offset of each NES PO for each PF.
[0101] In some embodiments, the position of the second type of PO within the first period can be determined based on the position of the first type of PO. In this scenario, the paging behaviors of different types of terminal devices will not affect each other. For example, when the first type of PO is a traditional PO and the second type of PO is an NES PO, the NES PO can be allocated based on the time / frequency offset of the traditional PO.
[0102] As an example, any PO in the second category of POs may be determined based on the location of any PO in the first category of POs.
[0103] As an example, any second-category PO may be determined by the locations of one or more first-category POs adjacent to the second-category PO.
[0104] As an example, in a DRX cycle, the total number of POs provided by the system to NES terminal devices may be the same as the total number of POs provided to traditional terminal devices, so as to ensure the same paging delay level for traditional terminal devices and NES terminal devices.
[0105] As an example, in a DRX cycle, the total number of POs provided by the system for NES terminal devices may be different from the total number of POs provided for traditional terminal devices to ensure paging requirements of different types of terminal devices.
[0106] As an example, the NES PO can be stored in each PF. For example, the NES PO can use the same paging frame as the traditional PO, and the index position of the NES PO in each PF can be set according to the same rules.
[0107] As an example, the position of the second type PO in the first period is determined according to the position of the first type PO and the first offset value. Optionally, the first offset value can be configured by the network device or a higher layer.
[0108] As an implementation manner, the first offset value may be provided through SIB or DCI.
[0109] As an example, the IDs of the first and second terminal devices are determined in the same manner, so that the first and second POs are assigned by offset values. The following uses a traditional PO as the first PO and an NES PO as the second PO as an example to illustrate the location determination methods for the first and second POs, respectively.
[0110] The first type of PO is located in any PF in the first period i s For: i s =floor(UE ID / N)mod N s ;
[0111] The second type of PO is located in any PF in the first period.s,NES for:
[0112] i S,NES =PO offset +floor(UE ID / N)mod N s ;
[0113] Among them, PO offset Indicates the first offset value, UE ID Indicates the ID of the terminal device, N indicates the number of PFs in a cycle, N s The first offset value is the PO offset of the NES terminal device compared with the traditional terminal device in receiving paging.
[0114] Optionally, UE ID It can be determined based on the international mobile subscriber identity (IMSI) or the 5G S-temporary mobile subscription identifier (5G-S-TMSI).
[0115] As an example, UE ID It can be IMSI mod 1024.
[0116] As an example, if the terminal device is in the eDRX cycle, the UE ID It can be 5G-S-TMSI mod 4096; otherwise, UE ID It can be 5G-S-TMSI mod 1024.
[0117] Optionally, the SFN corresponding to any PF in the first period needs to satisfy the formula: (SFN+PF offset )mod T=(TdivN)×(UE ID modN), where T represents the paging cycle, PF offset PF frame offset.
[0118] As an example, after the terminal device calculates the PF where the PO is located, it calculates the position of the NES PO on the PF. s,NES The terminal device can perform paging detection based on the calculated location, and so on, until the DCI corresponding to the terminal device is detected within the paging cycle. The above formula can be used to determine the exact location of the PF / PO corresponding to the traditional terminal device and the terminal device supporting the NES cell, respectively, to avoid any terminal device from detecting unnecessary multiple PF / POs.
[0119] For ease of understanding, combined Figure 3 , a paging method in which traditional PO and NES PO coexist is exemplified. Figure 3 Two DRX cycles are shown. In the two DRX cycles, paging frames (PF) appear periodically. Each PF contains two traditional POs and one NES PO. Figure 3 As shown, in each PF, after the traditional PO is determined, the NES PO can be determined based on the position of the adjacent PO and the corresponding offset value, or based on the position of the starting PO in the PF and the corresponding offset value.
[0120] In some embodiments, the first type of PO and the second type of PO can be located in different PFs within the first period. That is, the system can indicate different PFs for different scenarios or different terminal devices to determine the corresponding PO. For example, the first type of PO is located in the first PF, and the second type of PO is located in the second PF.
[0121] As an example, the first PF and the second PF may be one or more PFs respectively.
[0122] As an example, the first PF is a legacy PF, and the second PF is an NES PF. The PO located in the first PF can be used for legacy devices, while the PO located in the second PF can be used for NES devices. Legacy PFs are evenly distributed throughout the DRX cycle, while NES PFs can be different from legacy PFs. In an NES cell, both legacy and NES devices can be supported. Because NES devices can support different SSB cycles and on-demand SIBs, separate PFs and corresponding POs can be configured for NES devices.
[0123] As an example, the system can set a PF that is exclusive to the NES, or a specific PF number for use by the NES.
[0124] As an example, the system can be NES Configure one or more NES PFs in a paging cycle. For example, since multiple PFs are evenly distributed in a paging cycle, the simplest method is to configure only one PF in a paging cycle, that is, enable NES. NES = 1. This may require changes to the RRC configuration to allow more values to be configured for nAndPagingFrameOffset, that is, to allow more frequent paging cycles.
[0125] As an implementation method, N NES It can be extended from T / 16 to T / 32, T / 64, T / 128, and T / 256. So for the paging cycle T = 1280ms, if N NES=T / 128, we will have only one NES PF in this period. Therefore, in order to adapt to the increase in the number of terminal devices that need to be paged in a PF, it is necessary to increase the number of subframes used for PO and also increase the value range of Ns.
[0126] As an example, the system can designate odd-numbered PFs as the PF for traditional terminal devices (the first PF) and even-numbered PFs as the PF for NES terminal devices (the second PF). Each PF has its own PO. In other words, any PO in the PF corresponding to a traditional terminal device belongs to the PO of the traditional terminal device, and any PO in the PF corresponding to an NES terminal device belongs to the PO of the NES terminal device.
[0127] As an example, the DCI may be configured individually for each NES PF and indicate the starting offset of the PO.
[0128] As an implementation method, the first PF includes a first type of PO located at a first position, and the second PF includes a second type of PO located at a second position. The position of the first position in the first PF is the same as the position of the second position in the second PF, so that the system can indicate it.
[0129] As an implementation, the first PF includes a first type of PO located at a first position, and the second PF includes a second type of PO located at a second position. The position of the first position in the first PF is different from the position of the second position in the second PF, so as to distinguish different PFs.
[0130] As an example, the second PF can be determined based on the first PF and the second offset value. For example, the system can allocate NES PFs based on the time / frequency offset of the legacy PFs. Since the legacy PFs are evenly distributed across the DRX cycle, the NES PFs will also be evenly distributed across the DRX cycle, without affecting the paging behavior for legacy terminal devices.
[0131] As an example, the first PF and the second PF may coexist in the same cycle, or may not coexist in the same cycle.
[0132] As an example, the first cycle includes a first PF and a second PF. The second PF may be one or more PFs other than the first PF in the first cycle. For example, a traditional PF may coexist with an NES PF in the DRX cycle.
[0133] As an example, the second PF may be a PF in any period within the first period set. The first period set may be a set of multiple periods that include the second PF. The first information may be used to indicate whether the first period set includes the first period. That is, when different types of terminal devices correspond to different PFs, the terminal device may determine whether the first period includes the second PF based on the first information. For example, for an NES terminal device, if the first information indicates that the first period includes the NES PF, the terminal device performs detection within the first period; if the first information indicates that the first period does not include the NES PF, the terminal device does not perform detection within the first period.
[0134] As an implementation, when the first cycle is a DRX cycle, the system may specify NES PF information within each DRX cycle and notify the terminal device via the first information. For example, the system may determine whether the first cycle includes the NES PF based on the current cell load and / or the number of NES terminal devices requesting access.
[0135] As an implementation method, when the first cycle is a DRX cycle, the system can configure NES PF only in the specified DRX cycle. That is, some DRX cycles do not have NES PF, while some DRX cycles have NES PF.
[0136] For ease of understanding, combined Figure 4 , another paging method in which traditional PO and NES PO coexist is exemplified. Figure 4 Two DRX cycles are also shown. In the first DRX cycle, both traditional PF and NES PF are included; in the second DRX cycle, only traditional PF is included. The PO in the traditional PF is the traditional PO, and the PO in the NES PF is the NES PO. Figure 4 As shown, the position of NESPO in NES PF is the same as the position of traditional PO in traditional PF.
[0137] Example 2
[0138] The first information may include the type of the terminal device. As previously mentioned, the type of the terminal device is one of at least two terminal device types. For simplicity, the following description uses two types of terminal devices as an example. The terminal devices receiving paging in the first cycle can be grouped based on their types. In other words, the type of the terminal device can be used to determine whether a terminal device is a first type or a second type.
[0139] In some embodiments, since the PO corresponding to a terminal device is determined based on the terminal device's ID, different types of terminal devices can be grouped by ID. In other words, the ID determination methods for different types of terminal devices are differentiated to facilitate determining one or more POs corresponding to different types of terminal devices.
[0140] As an example, the IDs of the first and second category terminal devices can be determined differently. For example, if the first category terminal device is a traditional terminal device and the second category terminal device is an NES terminal device, the network can differentiate the ID values of traditional and NES terminal devices to support both traditional and NES cell-capable terminal devices. For example, the ID value range of traditional terminal devices differs from the ID value range of NES terminal devices.
[0141] As an example, the index or number of a terminal device among multiple terminal devices is used to determine the PF where one or more POs are located. Since different types of terminal devices have different ID determination methods, after multiple types of terminal devices receiving paging are uniformly numbered, the terminal device number value can distinguish different types of terminal devices and determine the PF corresponding to the terminal device.
[0142] As an example, all POs in the first cycle are used to send paging messages to terminal devices of type 1 and type 2. The PF where one or more POs corresponding to the terminal device are located is determined according to the paging density in the first cycle and the ID of the terminal device.
[0143] As an implementation manner, the paging density may be determined according to the number of the first category terminal devices and the second category terminal devices that receive paging within the first period.
[0144] As an implementation manner, the paging density may be determined according to the number of the first category terminal devices and the second category terminal devices in the first period.
[0145] As an example, the PF where one or more POs corresponding to the terminal device are located can be determined according to the numbers or indexes of all terminal devices that receive paging from the terminal device within the first period.
[0146] As an example, the PF where one or more POs corresponding to the terminal device are located can be determined according to the paging density and the number or index of all terminal devices that receive paging from the terminal device in the first period.
[0147] As an example, assume that a group of users receiving paging in the first cell includes traditional terminal devices and NES terminal devices. id The ID of the traditional terminal device, UE NES_idIt is the ID of the terminal device supporting the NES cell. Suppose there are M1 traditional terminal devices that receive paging and M2 NES terminal devices. The M1 UEs id and M2 UEs NES_id are numbered uniformly, and the index index′ can be expressed as:
[0148] index′ = 0, 1, 2, … M1 + M2 - 1.
[0149] Among them, the M1 + M2 terminal devices that receive paging can be numbered in sequence. After the unified numbering, the number of each terminal device can be determined according to the size relationship between M1 and M2. The number of terminal device i (i ∈ index′) can be determined according to the ID of terminal device i.
[0150] If M1 > M2, for the index range where index′ ≤ 2M2 - 1, the number of terminal device i can be:
[0151]
[0152] For the index range where index′ ≥ 2M2, the number of terminal device i can be:
[0153]
[0154] If M1 < M2, for the index range where index′ ≤ 2M1 - 1, the number of terminal device i can be:
[0155]
[0156] For the index range where index′ ≥ 2M1, the number of terminal device i can be:
[0157]
[0158] Let PF i correspond to the PF number of terminal device i among the M1 + M2 terminal devices; D f represents the paging density on PF, that is, the number of terminal devices allocated to each PF; D o can represent the number of terminal devices allocated to each PO.
[0159] PF i = i / D f , where
[0160] If Then the paging of terminal device i is on the 0th paging frame; if The paging of terminal device i is on the first paging frame; if The paging of terminal device i is performed in the second paging frame; and so on, until the DCI of terminal device i is detected within the paging cycle. Through the above method, the accurate location of the PF corresponding to the traditional terminal device and the terminal device supporting the NES cell can be obtained respectively, thereby avoiding the detection of multiple unnecessary PFs.
[0161] Example 3
[0162] The first information may include the type of PEI received by the terminal device and / or the type of the terminal device. For a network device, the first information according to the network device may include the type of PEI sent to the terminal device and / or the type of the terminal device.
[0163] It should be understood that the PEI in the embodiment of the present application can be replaced by an early paging indication (EPI).
[0164] In some embodiments, the PEI received by the terminal device may include at least two types of PEI. The at least two types of PEI may be used to indicate that at least two types of terminal devices receive paging messages. In other words, the PEI sent by the network side may be divided into at least two groups.
[0165] As an example, the at least two types of PEIs may include a traditional PEI for a traditional terminal device and an NES PEI for an NES terminal device. For example, the PEI received by the terminal device may be either a traditional PEI or an NES PEI.
[0166] As an example, when the network side sets the PEI, different types of PEIs may be different to facilitate differentiation by the terminal device. For example, the setting of the NES PEI may be different from the PEI of a traditional terminal device.
[0167] As an example, the network device may indicate different types of PEIs through DCI or PEI occasion (PEI-O).
[0168] As an example, different types of PEIs may have different identifiers, and the type of the PEI may be determined based on the identifier. The terminal device may determine the type of the PEI based on the received PEI identifier. The PEI identifier may be carried in the PEI or may be sent before the PEI.
[0169] As an example, the type of PEI may be used by the terminal device to determine whether it needs to be woken up for paging detection.
[0170] In some embodiments, since the PEI identifier can correspond to different types of terminal devices, the POs corresponding to different types of terminal devices can overlap, thereby saving resources. On overlapping POs, different types of terminal devices can determine whether to be awakened based on the type of PEI received. For example, when the PEI is an NES PEI, if the terminal device is a traditional terminal device, it does not detect the PO / PF indicated by the PEI and therefore does not need to be awakened; if the terminal device is an NES terminal device, it needs to be awakened to detect whether it has its own paging message.
[0171] As an example, when the first type of terminal device corresponds to the first type of PO and the second type of terminal device corresponds to the second type of PO, the first type of PO and the second type of PO completely overlap or partially overlap.
[0172] As an example, if traditional PO and NES PO completely overlap, the ID determination method for different types of terminal devices needs to be defined to be the same. In other words, the terminal device ID assigned to NES PO is the same as the terminal device ID assigned to traditional PO.
[0173] As an example, when the first type of terminal device corresponds to the first PF and the second type of terminal device corresponds to the second PF, the first PF and the second PF completely overlap or partially overlap.
[0174] As an example, NES PF / PO should overlap as much as possible with legacy PF / PO. When a network device (e.g., gNB) provides a paging message to a specific terminal device, it can be sent using the overlapping POs of the legacy and NES terminal devices. Furthermore, when the network device attempts to wake up the NES terminal device, the identification of the PEI can prevent the legacy terminal device from waking up unnecessarily.
[0175] In some embodiments, the PEI type sent by the network device to the terminal device can be determined based on the PEI setting. The NES PEI sent by the network device is different from the traditional PEI so that the traditional terminal device will not be awakened when the NES terminal device needs to be awakened.
[0176] Example 4
[0177] The first information may include whether the PF in the first cycle is continuous. If the PF in the first cycle is continuous, the network device and the terminal device perform paging behavior during the time period when the PF is continuous. If the PF in the first cycle is evenly distributed, the communication device executes the paging mechanism in a related manner.
[0178] In some embodiments, whether the PF in the first period is continuous refers to whether the PF in the first period is continuous in time domain resources.
[0179] To save energy on the network side, multiple PFs evenly distributed in a paging cycle can be configured as continuous or partially continuous PFs. In this scenario, the terminal device only needs to perform paging detection within continuous PFs, thereby increasing the terminal device's sleep time.
[0180] In some embodiments, part or all of the PFs in the first period are continuous in time domain resources. One or more POs corresponding to the terminal device can be determined based on the time domain positions of the continuous part or all of the PFs in the first period.
[0181] Taking the default paging cycle of T=128 radio frames as an example, when N=T / 16, there are only 8 paging frames every 1280ms. If the calculation formula of paging frame is (SFN+PF offset )mod T=(T div N)×(UE ID mod N), the 8 paging frames are evenly distributed in the paging cycle. In this formula, since (UE ID mod N) operation, according to UE ID Multiple terminal devices can be sequentially assigned to the eight PFs. To concentrate the PFs in a continuous time period, the calculation formula for the PF frame needs to be adjusted, while the PO calculation formula can remain unchanged.
[0182] As an example, when all PFs in the first period are continuous on the time domain resources, all PFs meet the following conditions:
[0183] (SFN+PF offset )mod T=UE ID mod N;
[0184] Among them, SFN is the system frame number, PF offset It represents the offset value of all PFs in the first cycle, and T represents the paging cycle.
[0185] If PF offset =0, then multiple consecutive PFs are located at the starting position of the first cycle. Figure 5 PF offset = 0. Where T = 128 wireless frames, N = T / 16. Figure 5 As shown, PF frames are concentrated in the first 8 radio frames of period T, and no paging is required in the subsequent frames.
[0186] Combined with the above Figures 2 to 5 The method for determining one or more corresponding POs on the terminal device side is introduced. The one or more POs are used by the network device side to send a paging message to the terminal device, so the network device side also needs to determine the one or more POs. Figure 6 The method for determining the one or more POs by the network device is described. Figure 2 The terms that have been explained in will not be repeated here.
[0187] See also Figure 6 In step S610, the network device determines one or more POs corresponding to the terminal device within the first period based on the first information. The network device is any network device or core network device corresponding to the first cell where the terminal device is located, and will not be described in detail here.

The first information can be referred to in the above embodiments and will not be repeated here.
[0189] In some embodiments, the network device first determines the identifier of the PEI to be sent to the terminal device, and then sends the PEI to the terminal device. The identifier of the PEI can be used by the terminal device to determine the type of the PEI, and the type of the PEI can be used to determine whether the terminal device is awakened.
