[0003] In related technologies, in satellite communication systems, a single satellite can provide a large coverage area. Generally speaking, the coverage area of ​​a satellite consists of multiple wave positions (beam coverage locations). The coverage diameter of a single wave position can reach tens of kilometers, and the coverage area of ​​a single satellite can include thousands of wave positions. Each wave position can provide coverage and service through a single beam.

[0004] Given the capabilities of satellites (e.g., transmission power, antenna configuration, etc.), satellites cannot simultaneously provide a large number of beams to cover every frequency band. In this situation, how terminal devices receive paging messages is a problem that needs to be solved. Summary of the Invention

[0092] The communication systems applicable to the embodiments of this application include, but are not limited to, Long Term Evolution (LTE) systems, 5th-generation (5G) systems, New Radio (NR) systems, and future evolution systems or multiple converged communication systems. The 5G system can be a non-standalone (NSA) 5G system or a standalone (SA) 5G system. The technical solutions of this application are also applicable to different network architectures, including but not limited to relay network architectures, dual-connectivity architectures, and vehicle-to-everything (V2X) communication architectures.

[0093] This application primarily relates to communication between terminal devices and network devices. Specifically:

[0094] The network device in this application embodiment can also be called an access network device, for example, it can be a base station (BS) (also called a base station device). A network device is a device deployed in a radio access network (RAN) to provide wireless communication functions. For example, in second-generation (2G) networks, the equipment providing base station functionality includes base transceiver stations (BTS); in third-generation (3G) networks, the equipment providing base station functionality includes nodes (NodeB); in fourth-generation (4G) networks, the equipment providing base station functionality includes evolved nodes (eNB); in wireless local area networks (WLANs), the equipment providing base station functionality is access points (APs); in NR, the equipment providing base station functionality includes next-generation node base stations (gNBs) and further evolved nodes (ng-eNBs). gNBs and terminal devices communicate using NR technology, while ng-eNBs and terminal devices communicate using evolved universal terrestrial radio access (E-UTRA) technology. Both gNBs and ng-eNBs can connect to the 5G core network. The network devices in this application embodiment also include devices that provide base station functions in future new communication systems.

[0095] In this application, "terminal equipment" can refer to various forms of access terminals, user units, user stations, mobile stations, mobile stations (MS), remote stations, remote terminals, mobile devices, user terminals, wireless communication equipment, user agents, or user devices. Terminal equipment can also be cellular phones, cordless phones, Session Initiation Protocol (SIP) phones, Wireless Local Loop (WLL) stations, Personal Digital Assistants (PDAs), handheld devices with wireless communication capabilities, computing devices, or other processing devices connected to a wireless modem, in-vehicle devices, wearable devices, terminal equipment in future 5G networks, or terminal equipment in future evolved Public Land Mobile Networks (PLMNs), etc. This application does not limit the scope of these terms. Terminal equipment can also be called user equipment (UE), terminal, etc.

[0096] As described in the background section, how terminal devices receive paging messages is a technical problem that urgently needs to be solved.

[0097] For example, if a satellite's coverage area contains 1000 spectral positions, and it wants to cover all spectral positions simultaneously, the satellite needs to activate 1000 beams at the same time, which poses a significant challenge to its capabilities. Therefore, satellite beams need to achieve coverage of each spectral position through Time Division Multiplexing (TDM). For instance, if a cell corresponds to 4 spectral positions, and one satellite beam needs to cover 16 spectral positions using TDM, then the time during which each cell is covered by the beam is not continuous.

[0098] Therefore, how to receive paging messages in scenarios with discontinuous coverage in residential areas is a technical problem that urgently needs to be solved.

[0099] In the technical solution of this application, the terminal device determines the location of the first paging opportunity by obtaining the first parameter, which enables the first paging opportunity to be within the cell coverage time. Therefore, the terminal device can receive the paging message within the cell coverage time, ensuring the successful reception of the paging message.

[0100] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0101] Referring to Figure 1, the method provided in this application specifically includes the following steps:

[0102] Step 101: The terminal device obtains the first parameter and determines the location of the first paging occasion (PO) based on the first parameter.

[0103] Step 102: The network device sends a paging message to the terminal device. Correspondingly, the terminal device receives the paging message. Specifically, the terminal device receives the paging message at the first paging opportunity.

[0104] It is understood that, in specific implementations, the communication method provided in this application can be implemented using a software program, which runs in a processor integrated within the chip or chip module. This method can also be implemented using a combination of software and hardware; this application does not impose any restrictions.

[0105] In this embodiment, the terminal device can determine the first parameter based on the non-continuous coverage configuration of the network device.

[0106] For example, network devices configure parameters such as paging cycle and coverage time window for terminal devices. Terminal devices can determine the cell coverage time and the primary parameter based on parameters such as paging cycle and coverage time window.

[0107] For example, network devices configure coverage time window information for terminal devices, specifically the start time, period, and length of the coverage time window. Terminal devices can determine the cell's coverage time and primary parameters based on the location of the coverage time window.

[0108] In this embodiment, the first parameter includes one or more of the following: the first number corresponding to each first system frame in the first system frame, the user identifier, and the first number of paging opportunities within the cell coverage time in a single paging cycle. The first system frame is a system frame within the cell coverage time, and the first number is obtained by numbering the first system frames in chronological order.

[0109] Refer to Figure 2 for details; the horizontal axis represents time. Within each paging cycle, there are multiple cell coverage times, and within each cell coverage time, the beam can provide coverage and service. As shown in Figure 2, some system frames (SFs) are within the cell coverage time, while others are not. System frames within the cell coverage time can be called the first system frame. System frames numbered 1-6 in Figure 2 are the first system frames.

[0110] In this embodiment, the first system frame, in addition to having an SFN, also corresponds to a first number. The first number is obtained by numbering the first system frames in chronological order.

[0111] Taking the 11 system frames shown in Figure 2 as an example, there are 11 system frames in the paging cycle, and the number of first system frames within the cell coverage time is 6. Then, by numbering the 6 first system frames in sequence, we can obtain the corresponding numbers 1-6 of the 6 first system frames.

[0112] Accordingly, referring to Figure 3, for periodic paging opportunities, some paging opportunities are within the cell coverage time, while others are not. The first quantity represents the number of paging opportunities within the cell coverage time in a single paging cycle. Taking Figure 3 as an example, for the 9 paging opportunities shown, 6 are within the cell coverage time, so the first quantity is 6.

[0113] In this embodiment, the user identifier can be a unique identifier pointing to the terminal device, such as the International Mobile Equipment Identity (IMEI), the International Mobile Subscriber Identification Number (IMSI), or the Temporary Mobile Subscriber Identity (TMSI). This application does not impose any restrictions on this.

[0114] Depending on the first parameter, the terminal device can determine the location of the first paging opportunity in different ways. This will be explained in detail below with reference to specific embodiments.

[0115] Example 1: The first parameter includes the first number of each first system frame and the user identifier. The terminal device calculates the first number corresponding to the paging frame where the first paging opportunity is located based on the paging configuration parameters and the first parameter. The paging frame is a first system frame within the first system frames. The terminal device calculates the paging opportunity index of the first paging opportunity within the paging frame based on the paging configuration parameters.

[0116] For details, please refer to Figure 4, which shows a communication method flow in this embodiment.

[0117] In step 401, the terminal device obtains the first parameter and the paging configuration parameter.

[0118] In step 402, the terminal device calculates the first number corresponding to the paging frame where the first paging opportunity occurs, based on the paging configuration parameters and the first parameter. The paging frame is selected from the first system frame in the first parameter.

[0119] Specifically, paging configuration parameters may include paging frame offset, paging period, and a second number of paging frames within a single paging period.

[0120] The first number corresponding to the paging frame satisfies the following formula: (SFNX+PF_offset) mod T= (T div N)×(UE_ID mod N), (1)

[0121] Wherein, SFNX represents the first paging frame number, PF_offset represents the paging frame offset, which can be the number of first system frames in a single paging cycle, T represents the number of first system frames in a paging cycle, N represents the second number, UE_ID represents the user identifier, mod represents the modulo operation, and div represents the integer division operation.

[0122] Since the first number is obtained by sequentially numbering the first system frame within the coverage time, the above formula can ensure that the calculated paging frame is also within the cell coverage time.

[0123] In step 403, the terminal device calculates the paging timing index of the first paging timing within the paging frame based on the paging configuration parameters.

[0124] Specifically, the paging configuration parameters include the third number of paging opportunities within a single paging frame, and the paging opportunity index of the first paging opportunity within the first system frame satisfies the following formula: i_s=floor(UE_ID / N)mod Ns, (2)

[0125] Where i_s represents the paging timing index of the first paging timing within the paging frame, UE_ID represents the user identifier, Ns represents the third quantity, N represents the second quantity, mod represents the modulo operation, and floor represents the floor operation.

[0126] The above formula provides a way to determine the first paging opportunity within a paging frame. Since the paging frame is within the cell coverage time, the first paging opportunity is also within the cell coverage time.

[0127] In step 404, the terminal device receives the paging message within the first paging opportunity.

[0128] Furthermore, the first number of the system frame can be in the range of [0, 1023].

[0129] The embodiments of this application combine paging configuration parameters and the above formulas (1) and (2) to determine the first paging timing, which is compatible with the existing first paging timing determination mechanism.

[0130] Example 2: The first parameter includes a user identifier and a first quantity. The terminal device determines the index of the first paging opportunity within the first system frame based on the remainder after dividing the user identifier by the first quantity.

[0131] For details, please refer to Figure 5, which shows a communication method flow in this embodiment.

[0132] In step 501, the terminal device determines the index of the first paging opportunity within the first system frame based on the remainder after dividing the user identifier by the first quantity.

[0133] Specifically, the terminal device uses the following formula to calculate the index of the first paging opportunity within the first system frame: UE-ID mod K = X, (3)

[0134] Wherein, UE_ID represents the user identifier, K represents the first quantity, X represents the index of the first paging time within the first system frame, and mod represents the modulo operation.

[0135] As previously stated, the first quantity represents the number of paging opportunities within the cell coverage time during a single paging cycle. As shown in Figure 3, the first quantity K is 6. Correspondingly, the paging opportunities within the first system frame are indexed from 0 to 5 (indexing starts from 0), and paging opportunities outside the first system frame are not included in the indexing.

[0136] Therefore, the index X of the first paging opportunity within the first system frame is UE-ID mod 6, with a remainder between 0 and 5. This means that the index of the first paging opportunity is also between 0 and 5, thus ensuring that the target paging time must be within the cell coverage time.

[0137] In step 502, the terminal device receives the paging message during the first paging opportunity.

[0138] This application provides a method for determining the first paging timing based on a first parameter, which includes wireless paging configuration parameters and a simple calculation method, reducing the computational complexity of the terminal device.

[0139] Example 3: The terminal device first determines the second paging timing based on the paging configuration parameters. If the second paging timing is not within the first system frame or is not within the cell coverage time, the terminal device determines the index of the first paging timing within the first system frame based on the remainder after dividing the user identifier by the first quantity.

[0140] Accordingly, if the second paging opportunity occurs within the first system frame or within the cell coverage time, the terminal device receives the paging message during the second paging opportunity.

[0141] In this embodiment, the paging configuration parameters include the system frame number, paging frame offset, paging period, the second number of paging frames within a single paging period, and the third number of paging opportunities within a single paging frame. The terminal device can determine the second paging opportunity according to the following formulas: (SFN+PF_offset)mod T=(T div N)×(UE_ID mod N), (4) i_s1=floor(UE_ID / N)mod Ns, (5)

[0142] Wherein, SFN represents the system frame number, PF_offset represents the paging frame offset, T represents the number of the first system frames within the paging period, N represents the second number, UE_ID represents the user identifier, mod represents the modulo operation, div represents the integer division operation, i_s1 represents the index of the second paging timing, UE_ID represents the user identifier, Ns represents the third number, N represents the second number, mod represents the modulo operation, and floor represents the floor operation.

[0143] Since the second paging timing is calculated based on the system frame number, and the system frame may be outside the cell coverage time, the second paging timing may also be outside the cell coverage time. If the second paging timing is outside the cell coverage time, the terminal device can determine the index of the first paging timing within the first system frame according to the aforementioned formula (3). The terminal device receives the paging message at the first paging timing.

[0144] Example 4: The network device configures the distribution of cell coverage time for the terminal device through the first information, or the first system frame.

[0145] For details, please refer to Figure 6, which shows a communication method flow in this embodiment.

[0146] In step 601, the network device sends first information to the terminal device. The first information is used to determine the distribution of cell coverage time or to determine the first system frame.

[0147] In one specific embodiment, the first information includes non-continuous coverage pattern parameters, which include one or more of the following: the temporal start position of the coverage time window, the length of the coverage time window, and the period of the coverage time window.

[0148] This embodiment configures the distribution of cell coverage time for terminal devices using non-continuous coverage pattern parameters.

[0149] In another specific embodiment, the first information includes one or more of the following coefficients: a first coefficient, a second coefficient, and a third coefficient, wherein one or more coefficients are used to determine the first system frame located within the cell coverage time.

[0150] In other words, the network device configures one or more coefficients for the terminal device, and the terminal device can determine the position of the first system frame based on these one or more coefficients.

[0151] Specifically, the system frame number SFN of each first system frame in the first system frame satisfies any of the following formulas: SFN mod X = i; (6) SFN mod X = i, i+1,…,i+N; (7)

[0152] Where X is the first coefficient, i is the second coefficient, and N is the third coefficient. Formula (6) indicates that the first system frame is a periodically distributed system frame; Formula (7) indicates that the first system frame is a periodically distributed N+1 consecutive system frames.

[0153] This application also discloses an embodiment for determining the timing of the first paging based on a second parameter. Please refer to Embodiment 5 for details.

[0154] Example 5: The terminal device obtains the second parameter and calculates the location of the first paging opportunity based on the second parameter.

[0155] For details, please refer to Figure 7, which shows a communication method flow in this embodiment.

[0156] In step 701, the terminal device obtains a second parameter. The second parameter may include one or more of the following: user identifier, a fourth number of cell coverage time windows within a single paging cycle, and a fifth number of paging opportunities within each cell coverage time window.

[0157] Specifically, the fourth quantity represents the number of cell coverage time windows within each paging cycle. Referring specifically to Figure 8, there are three coverage time windows within a single paging cycle, and the fourth quantity is 3. The terminal device can obtain the fourth quantity in the second parameter using the method described in Embodiment 4 above.

[0158] Specifically, the fifth quantity represents the number of paging opportunities within each cell coverage time window. Referring to Figure 3, if each cell coverage time window has 3 paging opportunities, then the fifth quantity is 3.

[0159] In step 702, the terminal device calculates the location of the first paging opportunity based on the second parameter. The first paging opportunity is located within the cell coverage time window.

[0160] Specifically, the terminal device can first determine a cell coverage time window based on the fourth quantity, and then determine the first paging opportunity within that cell coverage time window.

[0161] In one specific embodiment, the terminal device calculates the index of the first coverage time window in which the first paging opportunity occurs based on the user identifier and a fourth quantity. It then calculates the paging opportunity index within the first coverage time window based on the user identifier and a fifth quantity; the paging opportunity index is obtained by numbering all paging opportunities within the first coverage time window in chronological order.

[0162] Specifically, the terminal device can calculate the index of the first coverage time window using the following formula: UE-ID mod M=m, (8)

[0163] Wherein, UE_ID represents the user identifier, M represents the fourth quantity, and m represents the index of the first coverage time window.

[0164] Specifically, the terminal device can use the following formula to calculate the paging timing index of the first paging timing: UE-ID mod N'=n, (9)

[0165] Wherein, UE_ID represents the user identifier, N' represents the fifth quantity, and n represents the paging timing index of the first paging timing.

[0166] In step 703, the terminal device receives a paging message at the first paging time.

[0167] This application provides a novel way to determine the first paging timing by using a second parameter. Furthermore, it requires fewer second parameters, has a simpler calculation formula, and reduces the complexity of the terminal device.

[0168] Example 6: The network device configures the PMO information for the terminal device through the second information.

[0169] For details, please refer to Figure 9, which shows a communication method flow in this embodiment.

[0170] In step 901, the network device sends second information to the terminal device. The second information includes the starting position of the first PDCCH PMO within the service duration of each band position group. Each band position in the band position group corresponds to a synchronization signal block, and each cell coverage time window contains at least one band position group service duration.

[0171] Referring to Figure 8, within the first coverage time window, the cell coverage time window includes four band position groups (PMOs) with service durations. Each PMO group includes one band position, and each band position corresponds to one synchronization signal block. Each PMO group service duration includes three PMOs. The second information includes the starting position of the first PMO among the three PMOs.

[0172] Referring to Figure 10, within the first coverage time window, the cell coverage time window includes four band position groups (PMOs) with service durations of two band positions each, and each band position corresponding to a synchronization signal block. Each PMO service duration includes four PMOs. The second information includes the starting position of the first PMO among the four PMOs.

[0173] For terminal equipment, the PMO corresponding to each paging opportunity within each band position group service duration can be determined based on the second information.

[0174] Specifically, each paging opportunity corresponds to K consecutive PMOs within the service duration of each wave position group, where K represents the number of synchronization signal blocks corresponding to each wave position group, and the K PMOs correspond one-to-one with the K synchronization signal blocks corresponding to each wave position group.

[0175] Please refer to Figure 8 for details. The number of synchronization signal blocks K corresponding to each band position group is 1. Therefore, each paging opportunity corresponds to one PMO within the service duration of each band position group. Taking paging opportunity PO1 as an example, paging opportunity PO1 corresponds to one PMO (i.e., PMO1) within the service duration of the first band position group, and this PMO corresponds to synchronization signal block SSB1; correspondingly, paging opportunity PO1 corresponds to one PMO (i.e., PMO2) within the service duration of the second band position group, and this PMO corresponds to synchronization signal block SSB2; paging opportunity PO1 corresponds to one PMO (i.e., PMO3) within the service duration of the third band position group, and this PMO corresponds to synchronization signal block SSB3; paging opportunity PO1 corresponds to one PMO (i.e., PMO4) within the service duration of the fourth band position group, and this PMO corresponds to synchronization signal block SSB4.

[0176] Please refer to Figure 10 for details. The number of synchronization signal blocks K corresponding to each wave group is 2. Therefore, each paging opportunity corresponds to 2 PMOs within the service duration of each wave group. Specifically, the first wave group corresponds to synchronization signal blocks SSB1 and SSB2, the second wave group corresponds to synchronization signal blocks SSB3 and SSB4, the third wave group corresponds to synchronization signal blocks SSB5 and SSB6, and the fourth wave group corresponds to synchronization signal blocks SSB7 and SSB8. Taking paging timing PO1 as an example, paging timing PO1 corresponds to two PMOs (i.e., PMO1 and PMO2) within the service duration of the first wave group, and these two PMOs correspond to synchronization signal blocks SSB1 and SSB2; correspondingly, paging timing PO1 corresponds to two PMOs (i.e., PMO3 and PMO4) within the service duration of the second wave group, and these two PMOs correspond to synchronization signal blocks SSB3 and SSB4; paging timing PO1 corresponds to two PMOs (i.e., PMO5 and PMO6) within the service duration of the third wave group, and these two PMOs correspond to synchronization signal blocks SSB5 and SSB6; paging timing PO1 corresponds to two PMOs (i.e., PMO7 and PMO8) within the service duration of the fourth wave group, and these two PMOs correspond to synchronization signal blocks SSB7 and SSB8.

[0177] Furthermore, the PMOs corresponding to each paging opportunity are continuous in the time domain within the same wave group service duration.

[0178] Please refer to Figure 10 for details. There are 2 paging opportunities, and each paging opportunity corresponds to 2 consecutive PMOs within each wave group service duration. Taking the first one as an example, paging opportunity PO1 corresponds to the first group of PMO1 and PMO2 that are consecutive in the time domain; correspondingly, paging opportunity PO2 corresponds to the second group of PMO1 and PMO2 that are consecutive in the time domain.

[0179] This application provides a mapping method for PMOs corresponding to paging opportunities in non-continuous coverage scenarios, realizing the mapping between paging opportunities and PMOs within the coverage time, and further ensuring the successful reception of paging messages.
