[0023] The technical solution in this application will be described below with reference to the accompanying drawings.

[0024] Wireless communication system

[0025] Figure 1 is a diagram illustrating an example of the system architecture of a wireless communication system 100 to which an embodiment of the present application may be applied. The wireless communication system 100 may include a network device 110 and a terminal device 120. The network device 110 may be a device that communicates with the terminal device 120. The network device 110 may provide network coverage for a specific geographical area and may communicate with the terminal device 120 located within the coverage area. The terminal device 120 may access a network (e.g., a wireless network) through the network device 110. Optionally, the wireless communication system 100 may also include other network entities such as a network controller and a mobility management entity, which is not limited in the embodiments of the present application.

[0026] It should be understood that the technical solutions of the embodiments of the present application can be applied to various communication systems, such as: 5G system or new radio (NR), long term evolution (LTE) system, LTE frequency division duplex (FDD) system, LTE time division duplex (TDD), etc. The technical solutions provided in this application can also be applied to future communication systems, such as the sixth generation mobile communication system, satellite communication system, etc.

[0027] The terminal device in the embodiments of the present application may also be referred to as user equipment (UE), access terminal, user unit, user station, mobile station, mobile station (MS), mobile terminal (MT), remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent, or user device. The terminal device in the embodiments of the present application may refer to a device that provides voice and / or data connectivity to a user and can be used to connect people, objects, and machines, such as a handheld device with wireless connection function, a vehicle-mounted device, etc. The terminal device in the embodiments of the present application can be a mobile phone, a tablet computer, a laptop computer, a PDA, a mobile internet device (MID), a wearable device, a virtual reality (VR) device, an augmented reality (AR) device, a wireless terminal in industrial control, a wireless terminal in self-driving, a wireless terminal in remote medical surgery, a wireless terminal in a smart grid, a wireless terminal in transportation safety, a wireless terminal in a smart city, a wireless terminal in a smart home, etc. Optionally, the terminal device can be used to act as a base station. For example, the terminal device can act as a scheduling entity that provides sidelink signals between terminal devices in vehicle to everything (V2X) or device to device (D2D). For example, a cellular phone and a car communicate with each other using sidelink signals. The cellular phone and smart home devices communicate without relaying the communication signal through a base station.

The network device may be, for example, an access network device or a wireless access network device. For example, the network device may be a base station. The base station may broadly cover the following various names, or be replaced with the following names: NodeB, evolved NodeB (eNB), next generation NodeB (gNB), relay station, access point, transmission point (TRP), transmitting point (TP), home base station, network controller, access node, wireless node, access point (AP), transmission node, transceiver node, base band unit (BBU), remote radio unit (RRU), active antenna unit (AAU), remote radio head (RRH), central unit (CU), distributed unit (DU), positioning node, etc. The base station may be a macro base station, a micro base station, a relay node, a donor node or the like, or a combination thereof.

[0029] Application scenarios of communication systems

[0030] Currently, the main application scenarios of communication systems (e.g., 5G) can include enhanced mobile broadband (eMBB), ultra reliable low latency communication (URLLC), and massive machine type communication (mMTC).

[0031] Demand for eMBB, which can be applied to scenarios such as users accessing multimedia content, services, and data, is growing rapidly. Furthermore, eMBB can be deployed in diverse environments, such as indoors, in urban areas, and in rural areas. The capabilities and requirements for eMBB vary significantly in these environments.

[0032] URLLC can be applied to scenarios such as industrial automation, power automation, remote medical operations (surgery), and traffic safety. Typical features of mMTC include high connection density, small data volumes, latency-insensitive services, low module cost, and long service life.

[0033] Radio resource control (RRC) state and mobility management

[0034] Currently, the protocol defines three RRC states of terminal devices: RRC connected (RRC_connected) state, RRC idle (RRC-idle) state and RRC inactive (RRC-inactive) state.

[0035] The RRC connection state may refer to the state in which the terminal device is in when the RRC release is not performed after the random access process is completed. An RRC connection exists between the terminal device and a network device (e.g., an access network device). In the RRC connection state, the terminal device can transmit data with the network device, such as downlink data transmission and / or uplink data transmission. Alternatively, the terminal device can also transmit terminal device-specific data channels and / or control channels with the network device to transmit specific information or unicast information of the terminal device.

[0036] In the RRC connected state, the network device can determine the cell-level location information of the terminal device, that is, the network device can determine the cell to which the terminal device belongs. In the RRC connected state, after the terminal device moves, such as from one cell to another, the network device can control the terminal device to perform cell handover. Therefore, it can be seen that the mobility management of the terminal device in the RRC connected state may include cell handover. In addition, the mobility management of the terminal device in the RRC connected state can be controlled by the network device. Accordingly, the terminal device can switch to a designated cell according to the instructions issued by the network device.

[0037] The RRC idle state refers to the state of the terminal device when it is resident in a cell but is not performing random access. The terminal device usually enters the RRC idle state after being powered on or after RRC is released. In the RRC idle state, there is no RRC connection between the terminal device and the network device (such as the resident network device), the network device does not store the context of the terminal device, and no connection is established between the network device and the core network for the terminal device. If the terminal device needs to enter the RRC connected state from the RRC idle state, it is necessary to initiate the RRC connection establishment process.

[0038] In the RRC idle state, the core network (CN) can send a paging message to the terminal device, that is, the paging process can be triggered by the CN. Optionally, the paging area can also be configured by the CN. In some cases, for a terminal device in the RRC idle state, when the terminal device moves (for example, from one cell to another), the terminal device can initiate a cell reselection process. In other cases, for a terminal device in the RRC idle state, when the terminal device needs to access a cell, the terminal device can initiate a cell selection process. That is, the mobility management of the terminal device in the RRC idle state may include cell reselection and / or cell selection.

[0039] The RRC inactive state is defined to reduce air interface signaling, quickly restore wireless connections, and quickly resume data services. The RRC inactive state is a state between the connected and idle states. A terminal device previously entered the RRC connected state and then released the RRC connection with the network device, but the network device retained the terminal device's context. Furthermore, the connection established between the network device and the core network for the terminal device is not released. This means that the user plane and control plane bearers between the RAN and CN are still maintained, indicating a CN-NR connection.

[0040] In the RRC inactive state, the RAN can send a paging message to the terminal device, that is, the paging process can be triggered by the RAN. The RAN-based paging area is managed by the RAN, and the network equipment can know the location of the terminal device based on the RAN paging area level.

[0041] In some cases, for a terminal device in an RRC inactive state, when the terminal device moves (for example, from one cell to another), the terminal device may initiate a cell reselection process. In other cases, for a terminal device in an RRC inactive state, when the terminal device needs to access a cell, the terminal device may initiate a cell selection process. In other words, the mobility management of a terminal device in an RRC inactive state may include cell reselection and / or cell selection.

[0042] Release 18 (R18) Network Energy Saving Project

[0043] Energy consumption has become a significant component of operators' operating costs. According to a report by the Global System for Mobile Communications Association (GSMA), mobile network energy costs account for approximately 23% of operators' total costs. Most of this energy consumption comes from radio access networks, particularly active antenna units (AAUs), while data centers and fiber optic transmission contribute only a smaller share.

[0044] There are two types of energy consumption:

[0045] Dynamic part: such as energy consumption during data transmission / reception;

[0046] Static part: such as the energy consumption required to maintain the operation of the wireless access device (even if there is no continuous data transmission / reception).

[0047] The project should not only assess potential network energy consumption but also evaluate and balance the impact on network and user performance. For example, the project should not have a significant impact on key performance indicators (KPIs). These KPIs include spectrum efficiency, capacity, user perceived throughput (UPT), latency, terminal device power consumption, complexity, handover performance, call drop rate, and initial access performance.

[0048] Possible research directions (RP-234065) for this study include: defining universal signal / channel transmission adaptation techniques. For example, physical random access channel (PRACH) adaptation in the time domain. Another example is studying PRACH adaptation in the spatial domain. Another example is paging opportunity adaptation.

[0049] Spatial Domain Adaptation

[0050] Both paging resources and RACH resources correspond to SSB. Taking RACH as an example, a certain SSB direction corresponds to a series of RACH resources, where the resources can be time-frequency resources or preamble resources. Figure 2 shows the correspondence between RRB directions and RACH resources provided by related technologies. As shown in Figure 2, the number of resources corresponding to different SSB directions is the same. In this case, in order to receive and process RACH, the network needs to perform the same number of RACH receptions in each SSB direction, which means it needs to consume the same power. The spatial adaptation technology is proposed to solve this problem, but there is currently no clear solution for how to perform spatial domain adaptation.

[0051] Time Domain Adaptation

[0052] In paging scenarios, paging resources include paging hyperframes (PHs), which are continuous in time. This means that every hyperframe can be a PH. Therefore, even if the number of terminal devices is relatively small, network devices may need to remain active on all PHs, resulting in significant power consumption.

[0053] For the paging message sent by the core network (CN), the hyper system frame number (H-SFN) corresponding to the PH satisfies the following formula: H-SFN mod TeDRX_CN = (UE_ID_H mod TeDRX_CN). Among them, UE_ID_H represents the highest 13 bits of the hash identifier. TeDRX_CN is a terminal device-specific extended discontinuous reception (eDRX) cycle expressed in superframes. The time domain adaptation technology is proposed to avoid the network needing to remain activated on all PHs, thereby saving power consumption. However, there is currently no clear solution on how to perform time domain adaptation.

[0054] In summary, how to design RACH resources and / or paging resources to save network power is a concern of this application.

[0055] Figure 3 is a flow chart of a wireless communication method provided by an embodiment of the present application. Referring to Figure 3, in step S310, the terminal device receives configuration information of the network device. The configuration information may be configuration information related to RACH resources and / or paging resources. For example, the configuration information may include first configuration information and / or second configuration information. The first configuration information is used to configure RACH resources; the second configuration information is used to configure paging resources. If the configuration information includes both the first configuration information and the second configuration information, the first configuration information and the second configuration information may be sent simultaneously (i.e., configured simultaneously) or configured separately (i.e., configured separately, for example, carried in different configuration messages). The embodiment of the present application may improve the configuration method of RACH resources and / or paging resources to support adaptive allocation of RACH resources and / or paging resources in the time domain or in the spatial domain. The following provides detailed examples of the content and / or resource configuration method of the first configuration information and the second configuration information in combination with different embodiments.

[0056] Example 1: First configuration information

[0057] In some implementations, the first configuration information can independently configure RACH resources for different SSBs (it should be understood that the RACH resources mentioned in the embodiments of the present application can refer to one RACH resource or a RACH resource set. Therefore, in the absence of conflict, the RACH resources corresponding to the SSB mentioned later can also be understood or replaced by: RACH resources or RACH resource sets corresponding to the SSB). For example, the first configuration information is used to configure the correspondence between the SSB and the RACH resources, and in the first configuration information, the number of RACH resources corresponding to different SSBs is not exactly the same. In other words, the first configuration information contains a configuration that "the number of RACH resources corresponding to different SSBs is not exactly the same." For example, the first configuration information can configure the RACH resources corresponding to the first SSB and the second SSB. The number of RACH resources corresponding to the first SSB is 20, and the number of RACH resources corresponding to the second SSB is 10.

[0058] Different SSBs may correspond to different transmission directions. Therefore, the SSBs mentioned in the embodiments of the present application may be replaced by "SSB directions". The direction of the SSB may be expressed based on an SSB index. The SSB index is an identifier used when transmitting SSBs in different directions. Based on the SSB index, it is convenient to configure different RACH resources. As an example, for an SSB direction with more terminal devices, more RACH resources may be configured; for an SSB direction with fewer terminal devices, fewer RACH resources may be configured.

[0059] As can be seen from the above, the embodiments of the present application reasonably arrange RACH resources in the spatial domain (different SSB directions). Therefore, it is possible to achieve the effect of allowing different numbers of RACH resources in different SSB directions according to actual needs, thereby facilitating power saving of network devices.

[0060] It should be noted that RACH resources can include two dimensions, namely RACH time-frequency resources and preamble codes. RACH time-frequency resources can be understood as a larger dimension. Preamble codes can then be used to further distinguish within a RACH time-frequency resource. Using these two dimensions, large and small, RACH resources on different SSBs can be finely divided. The aforementioned correspondence between SSBs and RACH resources can be a correspondence between SSBs and RACH time-frequency resources and / or a correspondence between SSBs and preamble codes. In other words, the RACH resources corresponding to different SSBs can be distinguished from the RACH time-frequency resource dimension, or from the preamble dimension.

[0061] For example, the first configuration information is used to configure the RACH resources corresponding to the first SSB and the second SSB. The first SSB may correspond to a first RACH time-frequency resource or a set of time-frequency resources, and the second SSB may correspond to a second RACH time-frequency resource, where the first RACH time-frequency resource and the second RACH time-frequency resource are different time-frequency resources.

[0062] For another example, the first configuration information is used to configure RACH resources corresponding to a first SSB and a second SSB. The first SSB may correspond to a first preamble set, and the second SSB may correspond to a second preamble set. The preambles in the first preamble set and the second preamble set are different.

[0063] In some implementations, the first configuration information is used to configure one or more of the following corresponding to an SSB: the number of RACH resources; the starting index (or number) of the RACH resource; and the ending index (or number) of the RACH resource. For example, a RACH resource may correspond to a preamble within a time-frequency resource. In this case, each RACH resource actually represents a preamble. The RACH time-frequency resources and preambles within the entire RACH cycle can be numbered as a whole, and then the first configuration information can indicate the number of preambles corresponding to different SSBs. For example, assuming the number of RACH time-frequency resources is 4 and each RACH time-frequency resource contains 20 preambles, the index (or number) of the entire resource can be designed as 1, 2, ...80. Based on this, the first configuration information can separately indicate the number of RACHs corresponding to the SSB; and / or the first configuration information can indicate the starting index (or number) and ending index (or number) of the preamble corresponding to the SSB. By indicating the number, starting index, and / or ending index of RACH resources, signaling flexibility can be increased while minimizing signaling overhead.

[0064] In addition to configuring the correspondence between SSB and RACH resources, the first configuration information can also configure the correspondence between RACH resources and one or more service characteristics. The service characteristics mentioned here can be associated with one or more of the following: reduced-capability terminal equipment (redCap), small data (smallData) transmission, network slice access layer grouping (Network Slice AS Group, NSAG) and message 3 repetition (msg3-Repetition) transmission. For example, the RACH resources used for a certain service characteristic can be further divided by different SSB directions, thereby expanding the embodiment of the present application to scenarios where RACH is triggered in combination with different service characteristics.

[0065] In some implementations, the configuration information mentioned above may further include third configuration information. The third configuration information is used to configure the correspondence between SSBs and RACH resources, and in the third configuration information, the number of RACH resources corresponding to different SSBs is the same. The embodiment of the present application does not specifically limit the type of RACH resources configured by the third configuration information. For example, the third configuration information can be used to configure one or more of the following RACH resources: RACH resources corresponding to four-step random access, RACH resources corresponding to two-step random access, and RACH resources for one or more service characteristics. For the description of service characteristics, please refer to the previous text and will not be repeated here.

[0066] The first configuration information mentioned above can be understood as the configuration information provided in the embodiments of the present application, and the third configuration information can be understood as the configuration information provided in the related art. For ease of understanding, the RACH resources configured by the first configuration information are referred to as new RACH resources, and the RACH resources configured by the third configuration information are referred to as old RACH resources. New terminal devices can use the new RACH resources, and old terminal devices can use the old RACH resources. In the embodiments of the present application, new and old RACH resources can be configured on the same carrier for joint use, thereby supporting new and old terminal devices.

[0067] In some implementations, the new RACH resources and the old RACH resources can be distinguished in the time domain. For example, the new RACH resources and the old RACH resources can correspond to different random access occasions (ROs). For example, the new RACH resources can be configured on the new RO, occupying preambles 0-19, with the remaining preambles 20-63 available for non-contention random access.

[0068] In other implementations, the new RACH resources and the old RACH resources may share time domain resources (e.g., share RO) and be differentiated at the preamble granularity. For example, the new RACH resources include the first set of preambles in the first RO, and the old RACH includes the second set of preambles in the first RO.

[0069] Furthermore, in a scheme where new RACH resources share an RO with old RACH resources, the new RACH resources can occupy preambles originally used for non-contention random access scenarios. For example, a first RO includes a first group of preambles and a second group of preambles, the old RACH resources include the first group of preambles, and the new RACH resources include the second group of preambles. According to the third configuration information, the second group of preambles is part or all of the preambles used for non-contention random access. In other words, the new RACH resources are random access resources divided from the preambles originally used for non-contention random access.

[0070] As a more specific example, the third configuration information configures 4 ROs, each RO occupies 20 preambles. An RO contains 64 preambles. According to the third configuration information, the remaining preambles are counted as group-B and used as non-competitive preambles (for non-competitive random access scenarios). In this case, the new RACH resources can share the RO with the old RACH resources, and divide the resources from the group-B in the RO. For example, for each RO, the old RACH resources occupy preambles 0-19, the new RACH resources occupy preambles 20-39, and the remaining preambles 40-63 are used as non-competitive preambles (for non-competitive random access scenarios). The embodiment of the present application facilitates the common use of new and old RACH resource configurations on the same carrier, thereby supporting new and old terminal devices.

[0071] Example 2: Second configuration information

[0072] The second configuration information may be used to independently configure paging resources in the time domain.

[0073] In some implementations, the second configuration information includes a first parameter. The first parameter is used to determine or adjust the density of the paging superframe (PH) in the time domain. For example, the first parameter is used to determine or adjust the number of superframes spaced between two consecutive paging start positions; in other words, the number of superframes spaced between two consecutive paging start positions is associated with the first parameter. For example, assuming that the first PH is numbered x and the second PH is numbered y, the value of the first parameter can be y-x+1. By changing the value of the first parameter, the number of superframes spaced between the first PH and the second PH can be adjusted. It should be understood that the paging start position mentioned in the embodiment of the present application refers to the paging position corresponding to one or multiple consecutive PHs. That is, one paging start position corresponds to one or multiple consecutive PHs.

[0074] Based on the first parameter, the embodiment of the present application changes the form of continuous paging in the superframe domain in the related art to a form of paging again after a certain number of superframes, thereby helping network devices to save energy.

[0075] For example, the PH corresponding to a paging start position satisfies the following formula:

[0076] H-SFN mod TeDRX_CN = (TeDRX_CN / X)*(UE_ID_H mod X), where H-SFN represents the frame number of the superframe, TeDRX_CN represents a parameter related to time and period (such as the period parameter of eDRX), X represents the first parameter, UE_ID_H represents the identification-related information of the terminal device (such as the hash identifier of the terminal device), and mod represents a remainder operation. It should be understood that the names of the variables in the above formula are only examples and can be replaced by other variable names. According to the above formula, it can be seen that a paging start position will appear for every TeDRX_CN / X H-SFNs.

[0077] Since network devices need to save energy at certain intervals, it is best to do more paging each time they wake up to avoid too high a frequency of sleep and wake-up. Therefore, in some implementations, a second parameter can be introduced in the second configuration information to facilitate control of the number of pagings that the network device needs to perform when waking up once. In other words, the second parameter is used to determine or adjust the number of paging resources corresponding to a paging start position (or the number of paging resources accommodated by a paging start position). In other words, the number of paging resources corresponding to a paging start position is associated with the second parameter.

[0078] In some implementations, the second parameter is used to determine or adjust the number of consecutive PHs corresponding to a paging start position (or, in other words, the second parameter is used to determine or adjust the number of PHs that a paging start position can accommodate). By configuring the second parameter, several consecutive PHs will appear every few superframes. As can be seen, the embodiments of the present application avoid requiring network devices to wake up frequently in the time domain, but instead try to arrange related signals within a continuous and limited period of time, while allowing network devices to be in a sleep state during other longer continuous periods of time, thereby achieving power saving.

[0079] For example, the consecutive paging superframes corresponding to a paging start position and the starting positions of the paging time windows (PTWs) in the consecutive paging superframes satisfy the following formula: PH=ieDRX_CN div 8;

[0080] SFN = 128*(ieDRX_CN mod 8), where ieDRX_CN = floor(UE_ID_H / TeDRX_CN) mod (8*Y);

[0081] Among them, PH represents an offset relative to a paging start position. For example, if PH=0, it is a paging superframe that is the same as the paging start position. If PH=1, it is a superframe that is offset from the paging start position by 1 superframe. SFN represents the starting position of PTW. TeDRX_CN represents a parameter related to time and period (such as the period parameter of eDRX). UE_ID_H represents identification-related information of the terminal device (such as the hash identifier of the terminal device). mod represents a remainder operation. Floor represents a round-down operation. Div represents a division operation. Y represents a second parameter.

[0082] According to the above formula, each paging start position corresponds to Y PHs (can accommodate Y PHs). In the Y PHs, each PTW window is arranged at intervals of 128 frames.

[0083] In some implementations, the second parameter is used to determine or adjust the number of PTWs corresponding to a paging start location (or, in other words, the second parameter is used to determine or adjust the number of PTWs that a paging start location can accommodate). By configuring the second parameter, a paging start location can accommodate multiple consecutive PHs. The design of consecutive PHs can enable the network device to perform more paging after waking up, reducing the frequency of sleep and wakeup.

[0084] For example, the consecutive paging superframes corresponding to one paging start position and the starting positions of the PTWs in the consecutive paging superframes satisfy the following formula: PH=ieDRX_CN div 8;

[0085] SFN = 128*(ieDRX_CN mod 8), where ieDRX_CN = floor(UE_ID_H / TeDRX_CN) mod (Z);

[0086] Among them, PH represents an offset relative to a paging start position. For example, if PH=0, it is a paging superframe that is the same as the paging start position. If PH=1, it is a superframe that is offset from the paging start position by 1 superframe. SFN represents the starting position of PTW. TeDRX_CN represents a parameter related to time and period (such as the period parameter of eDRX). UE_ID_H represents the identification-related information of the terminal device (the hash identifier of the terminal device). mod represents a remainder operation. Floor represents a round-down operation. Div represents a division operation. Z represents the second parameter.

[0087] In some implementations, the second configuration information also includes a third parameter, which is used to determine or adjust the interval between two PTWs. In related art, the interval between two PTWs is fixed at 128 frames. This application introduces a third parameter to flexibly adjust the number of frames between two PTWs.

[0088] For example, the consecutive paging superframes corresponding to one paging start position and the starting positions of the PTWs in the consecutive paging superframes satisfy the following formula: PH=ieDRX_CN div(1024 / W);

[0089] SFN = 128*(ieDRX_CN mod(1024 / W)), where ieDRX_CN = floor(UE_ID_H / TeDRX_CN) mod(Z);

[0090] Among them, PH represents an offset relative to a paging start position. For example, if PH=0, it is the paging superframe that is the same as the paging start position. If PH=1, it is a superframe that is offset from the paging start position by 1 superframe. SFN represents the starting position of PTW. TeDRX_CN represents a parameter related to time and period (such as the period parameter of eDRX). UE_ID_H represents the identification-related information of the terminal device (the hash identifier of the terminal device). mod represents a remainder operation. Floor represents a round-down operation. Div represents a division operation. Z is used to determine the number of PTWs corresponding to a paging start position. W represents a third parameter.

[0091] For another example, the consecutive paging superframes corresponding to one paging start position and the starting positions of the PTWs in the consecutive paging superframes satisfy the following formula: PH=ieDRX_CN div(1024 / W);

[0092] SFN = 128*(ieDRX_CN mod(1024 / W)), where ieDRX_CN = floor(UE_ID_H / TeDRX_CN) mod(8*Y);

[0093] Among them, PH represents an offset relative to a paging start position. For example, if PH=0, it is the paging superframe that is the same as the paging start position. If PH=1, it is a superframe that is offset from the paging start position by 1 superframe. SFN represents the starting position of PTW. TeDRX_CN represents a parameter related to time and period (such as the period parameter of eDRX). UE_ID_H represents the identification-related information of the terminal device (the hash identifier of the terminal device). mod represents a remainder operation. Floor represents a round-down operation. Div represents a division operation. Y is used to determine the number of consecutive PHs corresponding to a paging start position. W represents the third parameter.

[0094] The above describes in detail the adaptive adjustment of paging resources in the time domain. The following describes in detail the adaptive adjustment of paging resources in the spatial domain.

[0095] In some implementations, the second configuration information can independently configure paging resources for different SSBs. For example, the second configuration information is used to configure the correspondence between SSBs and paging resources, and in the second configuration information, the number of paging resources corresponding to different SSBs is not exactly the same. In other words, the second configuration information includes a configuration that "the number of paging resources corresponding to different SSBs is not exactly the same." The embodiment of the present application reasonably arranges paging resources in the spatial domain, and can achieve the effect of allowing different numbers of paging resources in different SSB directions according to actual needs, thereby facilitating power saving of network devices.

[0096] Different SSBs may correspond to different transmission directions. Therefore, the SSBs mentioned in the embodiments of the present application may be replaced by "SSB directions". The SSB direction may be expressed based on the SSB index. Therefore, independently configuring paging resources for different SSBs may also be understood as independently configuring paging resources for different SSB indexes, that is, multiple SSB indexes have their own corresponding paging resources. The SSB index is an identifier used when sending SSBs in different directions, which facilitates configuration for different paging resources. As an example, for an SSB direction with more terminal devices, more paging resources may be configured; for an SSB direction with fewer terminal devices, fewer paging resources may be configured.

[0097] Paging resources include paging monitoring occasions. In some implementations, the paging monitoring occasions corresponding to different SSBs can be independently configured, so that the paging resources on different SSBs can be finely divided.

[0098] In some implementations, the configuration information mentioned above may further include fourth configuration information. The fourth configuration information is used to configure the correspondence between SSBs and paging resources, and in the fourth configuration information, the number of paging resources corresponding to different SSBs is the same. The second configuration information mentioned above can be understood as the configuration information provided by the embodiment of the present application, and the fourth configuration information can be understood as the configuration information provided by the relevant technology. The paging configured by the second configuration information can be used by new terminal devices, and the paging resources configured by the fourth configuration information can be used by old terminal devices. The paging resources configured in the two ways can exist at the same time, so that new and old terminal devices can use their respective adapted paging resources for paging.

[0099] The time domain positions of the paging resources configured by the second configuration information and the paging resources configured by the fourth configuration information may be different. For example, the PO corresponding to the paging resources configured by the second configuration information is located at time domain position 1, and the PO corresponding to the paging resources configured by the fourth configuration information is located at time domain position 2, and time domain position 1 and time domain position 2 are located at different positions in the time domain.

[0100] In some implementations, a first offset may be introduced in the second configuration information, and the position of the PO corresponding to the paging resource may be determined based on the first offset. Based on the first offset, the paging resources configured by the second configuration information and the fourth configuration information may correspond to different POs. For example, the PO configured according to the configuration method provided by the relevant technology occupies a total of 4 positions from 0 to 3. Then, based on the first offset, the PO configured in the embodiment of the present application may be counted starting from 4. By introducing the first offset, the paging resources of new users and old users can be conveniently separated in the time domain, thereby ensuring the backward compatibility of the solution.

[0101] Exemplarily, the position of the PO corresponding to the paging resource configured by the second configuration information satisfies the following formula: i_s=floor(UE_ID / N)mod Ns+Offset1;

[0102] Among them, UE_ID represents the identification related information of the terminal device, N represents the number of PFs included in the paging cycle, Ns represents the number of POs in the PF, Offset1 represents the first offset, i_s represents the parameter used to determine the PO, and floor represents the rounding down operation.

[0103] In some implementations, a second offset may be introduced in the second configuration information; or, the second configuration information includes a third offset, and based on the third offset, the paging resources configured by the second configuration information and the fourth configuration information correspond to different paging monitoring occasions. The second offset is used to determine the position of the PTW (or SFN) corresponding to the paging resource. Based on the second offset, the paging resources configured by the second configuration information and the fourth configuration information may correspond to different PTWs. That is, the second offset may distinguish the SFN configured in the embodiment of the present application from the SFN configured in the related art. For example, if the SFN corresponding to the paging resource configured in accordance with the related art occupies SFNs N to N+9, then the SFN occupied by the paging resource configured in the embodiment of the present application may start from N+10.

[0104] For example, the position of the SFN or PTW corresponding to the paging resource configured by the second configuration information satisfies the following formula:

[0105] SFN = (128*ieDRX_CN + Offset2) mod 1024; where SFN represents the starting position of the PTW, ieDRX_CN represents a parameter determined based on the eDRX cycle parameter, mod represents a modulo operation, and Offset2 represents a second offset. For example, ieDRX_CN = floor(UE_ID_H / TeDRX_CN) mod (8). UE_ID_H identifies the terminal device's identification-related information (such as a hash identifier of the terminal device), and TeDRX_CN represents a parameter related to time and cycle (such as the eDRX cycle parameter).

[0106] For another example, the position of the SFN or PTW corresponding to the paging resource configured by the second configuration information satisfies the following formula:

[0107] SFN = (128 * (ieDRX_CN mod 8) + Offset2) mod 1024; where SFN represents the starting position of the PTW, ieDRX_CN represents a parameter determined based on the eDRX cycle parameter, mod represents a modulo operation, and Offset2 represents a second offset. For example, ieDRX_CN = floor(UE_ID_H / TeDRX_CN) mod (8), where UE_ID_H identifies information related to the terminal device (such as a hash identifier of the terminal device), and TeDRX_CN represents a parameter related to time and cycle (such as an eDRX cycle parameter).

[0108] For another example, the position of the SFN or PTW corresponding to the paging resource configured by the second configuration information satisfies the following formula:

[0109] SFN = (W*(ieDRX_CN mod(1024 / W))+Offset2) mod 1024; where SFN represents the starting position of the PTW, ieDRX_CN represents a parameter determined based on the cycle parameter of eDRX, mod represents a modulo operation, Offset2 represents a second offset, and W is used to determine the interval between two PTWs. For example, ieDRX_CN = floor(UE_ID_H / TeDRX_CN) mod (8). UE_ID_H identifies identification-related information of the terminal device (such as a hash identifier of the terminal device), and TeDRX_CN represents a parameter related to time and period (such as the cycle parameter of eDRX).
