[0064] The communication system to which embodiments of the present application are applicable includes, but is not limited to, a Long Term Evolution (LTE) system, a 5th-Generation (5G) system, a New Radio (NR) system, and a future evolution system or a multi-communication convergence system. The 5G system can be a Non-Stand Alone (NSA) 5G system or a Stand Alone (SA) 5G system. The technical solutions of the present application are also applicable to different network architectures, including but not limited to a relay network architecture, a dual connectivity architecture, a Vehicle-to-Everything (V2X) architecture, and the like.

[0065] The present application mainly relates to communication between a terminal device and a network device. In which:

[0066] The network device in the embodiments of the present application can also be referred to as an access network device, for example, a base station (Base Station, BS) (also referred to as a base station device), and the network device is a device deployed in a radio access network (Radio Access Network, RAN) to provide wireless communication functions. For example, the device providing the base station function in the second generation (2nd-Generation, 2G) network includes a base wireless transceiver station (Base Transceiver Station, BTS), the device providing the base station function in the third generation (3rd-Generation, 3G) network includes a node B (NodeB), the device providing the base station function in the fourth generation (4th-Generation, 4G) network includes an evolved node B (evolved NodeB, eNB), in the wireless local area network (Wireless Local Area Networks, WLAN), the device providing the base station function is an access point (Access Point, AP), the device providing the base station function in the NR is a next generation node base station (next generation NodeBase station, gNB), and a continuously evolved node B (ng-eNB), wherein the gNB and the terminal device communicate with each other by using the NR technology, the ng-eNB and the terminal device communicate with each other by using the evolved universal terrestrial radio access (Evolved Universal Terrestrial Radio Access, E-UTRA) technology, and the gNB and the ng-eNB can be connected to the 5G core network. The network device in the embodiments of the present application also includes devices providing base station functions in future new communication systems and the like.

[0067] The terminal equipment in the embodiments of the present application can refer to various forms of access terminals, user units, user stations, mobile stations, mobile stations (Mobile Station, MS), remote stations, remote terminals, mobile devices, user terminals, wireless communication devices, user agents or user devices. The terminal equipment can also be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with wireless communication function, a computing device or other processing device connected to a wireless modem, a vehicle-mounted device, a wearable device, a terminal equipment in a future 5G network or a terminal equipment in a future evolved Public Land Mobile Network (PLMN), etc. The embodiments of the present application are not limited thereto. The terminal equipment can also be referred to as user equipment (User Equipment, UE), terminal, etc.

[0068] As described in the background, how the terminal equipment receives the paging message is a technical problem to be solved.

[0069] For example, the coverage area of a satellite contains 1000 wave positions, if it meets the requirement of covering all wave positions at the same time, the satellite needs to activate 1000 beams at the same time, which poses a great challenge to the satellite capability. Therefore, the satellite beam needs to realize the coverage of each wave position through Time Division Multiplexing (TDM). For example, a cell corresponds to 4 wave positions, and a satellite beam needs to cover 16 wave positions through TDM. Therefore, the time of each cell covered by the beam is discontinuous.

[0070] Therefore, in the scenario of discontinuous coverage of a cell, how to receive the paging message is a technical problem to be solved.

[0071] In the technical solution of the present application, the terminal equipment determines the position of the first paging occasion through the acquired first parameter, which can make the first paging occasion located in the cell coverage time. Therefore, the terminal equipment can receive the paging message in the cell coverage time, and the successful reception of the paging message is ensured.

[0072] The specific embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0073] Referring to Figure 1 The method provided by the present application specifically includes the following steps:

[0074] Step 101: The terminal device acquires a first parameter, and determines a position of a first paging occasion (PO) according to the first parameter.

[0075] Step 102: The network device sends a paging message to the terminal device. Correspondingly, the terminal device receives the paging message. In this case, the terminal device receives the paging message at the first paging occasion.

[0076] It can be understood that, in a specific implementation, the communication method can be implemented in the form of a software program running in a processor integrated in a chip or a chip module. The method can also be implemented in the form of software combined with hardware, and the present application does not make any limitation.

[0077] In this embodiment, the terminal device can determine the first parameter according to a configuration of discontinuous coverage configured by the network device.

[0078] For example, the network device configures a terminal device with a paging cycle, a coverage time window and other parameters. The terminal device can determine the coverage time of a cell and the first parameter according to the paging cycle, the coverage time window and other parameters.

[0079] For another example, the network device configures a terminal device with information of a coverage time window, which can be a start time position of the coverage time window, a period and a length of the coverage time window. The terminal device can determine the coverage time of a cell and the first parameter according to the position of the coverage time window.

[0080] In this embodiment, the first parameter includes one or more of the following: a first number corresponding to each first system frame in a first system frame, a user identifier, and a first number of paging occasions in a single paging cycle within the coverage time of a cell, the first system frame being a system frame within the coverage time of a cell, and the first number being obtained by numbering the first system frame in time sequence.

[0081] For details, please refer to Figure 2 , the horizontal axis represents time. There are multiple cell coverage times in each paging cycle, and each cell coverage time can be covered by a beam and provide services. As can be seen from Figure 2 , some system frames (SFs) are within the coverage time of a cell, and some system frames are not within the coverage time of a cell. The system frames within the coverage time of a cell can be referred to as first system frames. As shown in Figure 2 , the system frames numbered 1-6 are first system frames.

[0082] In this embodiment, the first system frame has a first number in addition to a system frame number (SFN). The first number is obtained by numbering the first system frame in time sequence.

[0083] by Figure 2 Taking the 11 system frames shown in 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, the numbers 1-6 corresponding to the 6 first system frames can be obtained.

[0084] Accordingly, refer to Figure 3 For periodic paging occasions, some paging occasions are within the cell coverage time, while some paging occasions are not within the cell coverage time. The first number represents the number of paging occasions within the cell coverage time in a single paging cycle. Figure 3 For example, for the 9 paging occasions shown, 6 are within the cell coverage time, and the first number is 6.

[0085] In this embodiment, the user identifier can be an identifier that uniquely points 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.

[0086] According to different first parameters, the terminal device may determine the position of the first paging occasion in different ways, which will be described in detail below with reference to specific embodiments.

[0087] In embodiment 1, the first parameter includes a first number and a user identifier for each first system frame. The terminal device calculates a first number corresponding to a paging frame in which a first paging opportunity is located based on a paging configuration parameter and the first parameter, where the paging frame is a first system frame in the first system frame; and the terminal device calculates a paging opportunity index within the paging frame for the first paging opportunity based on the paging configuration parameter.

[0088] For details, please refer to Figure 4 , Figure 4 A communication method flow in this embodiment is shown.

[0089] In step 401, the terminal device obtains a first parameter and a paging configuration parameter.

[0090] In step 402, the terminal device calculates a first number corresponding to a paging frame in which a first paging occasion is located according to a paging configuration parameter and a first parameter, wherein the paging frame is selected from a first system frame in the first parameter.

[0091] Specifically, the paging configuration parameter can include a paging frame offset, a paging cycle, and a second number of paging frames in a single paging cycle.

[0092] The first number corresponding to the paging frame satisfies the following formula:

[0093] (SFNX + PF_offset ) mod T = (T div N)×(UE_ID mod N), (1)

[0094] where SFNX represents the first number of the paging frame, PF_offset represents the paging frame offset, which can be specifically the number of first system frames in a single paging cycle, T represents the number of first system frames in the paging cycle, N represents the second number, UE_ID represents a user identifier, mod represents a modulo operation, and div represents an integer division operation.

[0095] Since the first number is sequentially numbered for the first system frame located in the coverage time, the calculated paging frame is also located in the cell coverage time through the above formula.

[0096] In step 403, the terminal device calculates a paging occasion index of the first paging occasion in the paging frame according to the paging configuration parameter.

[0097] Specifically, the paging configuration parameter includes a third number of corresponding paging occasions in a single paging frame, and the paging occasion index of the first paging occasion in the first system frame satisfies the following formula:

[0098] i_s = floor (UE_ID / N) mod Ns, (2)

[0099] where i_s represents the paging occasion index of the first paging occasion in the paging frame, UE_ID represents a user identifier, Ns represents the third number, N represents the second number, mod represents a modulo operation, and floor represents a floor operation.

[0100] The above formula provides a way to determine the first paging occasion in the paging frame. Since the paging frame is located in the cell coverage time, the first paging occasion is also located in the cell coverage time.

[0101] In step 404, the terminal device receives a paging message in the first paging occasion.

[0102] Further, the first number of the system frame can be in the range of [0, 1023].

[0103] The embodiments of the present application determine the first paging occasion in combination with the paging configuration parameter and the above formulas (1) and (2), which can be compatible with the existing first paging occasion determination mechanism.

[0104] In the embodiment 2, the first parameter includes a user identifier and a first number. The terminal device determines the index of the first paging occasion in the first system frame according to a remainder of the user identifier divided by the first number.

[0105] For details, refer to Figure 5 , Figure 5 A communication method flow is shown in the embodiment.

[0106] In step 501, the terminal device determines the index of the first paging occasion in the first system frame according to a remainder of the user identifier divided by the first number.

[0107] Specifically, the terminal device calculates the index of the first paging occasion in the first system frame by using the following formula:

[0108] UE-ID mod K = X, (3)

[0109] Wherein, UE_ID represents the user identifier, K represents the first number, X represents the index of the first paging occasion in the first system frame, and mod represents the remainder operation.

[0110] As mentioned above, the first number represents the number of paging occasions in a single paging cycle within the cell coverage time. As Figure 3 shown, the first number K is 6. Accordingly, the indexes of the paging occasions in the first system frame are 0-5 (the index starts from 0), and the paging occasions outside the first system frame are not involved in the numbering of the index.

[0111] Then, the index X of the first paging occasion in the first system frame is UE-ID mod 6, and the remainder is between 0-5, which means that the index of the first paging occasion is also between 0-5, thereby ensuring that the target paging time is necessarily within the cell coverage time.

[0112] In step 502, the terminal device receives the paging message in the first paging occasion.

[0113] The embodiment of the application provides a way of determining the first paging occasion according to the first parameter, wireless paging configuration parameters, and the calculation method is simple, which reduces the calculation complexity of the terminal device.

[0114] In the embodiment 3, the terminal device first determines the second paging occasion according to the paging configuration parameters, and in the case that the second paging occasion is not in the first system frame or is not in the cell coverage time, the terminal device determines the index of the first paging occasion in the first system frame according to a remainder of the user identifier divided by the first number.

[0115] Correspondingly, if the second paging occasion is in the first system frame or is in the cell coverage time, the terminal device receives the paging message at the second paging occasion.

[0116] In this embodiment, the paging configuration parameter includes a system frame number, a paging frame offset, a paging cycle, a second number of paging frames in a single paging cycle, and a third number of corresponding paging occasions in a single paging frame. The terminal device can determine the second paging occasion according to the following formula:

[0117] (SFN+ PF_offset ) mod T = (T div N)×(UE_ID mod N), (4)

[0118] i_s1 = floor (UE_ID / N) mod Ns, (5)

[0119] Wherein, SFN represents the system frame number, PF_offset represents the paging frame offset, T represents the number of first system frames in the paging cycle, 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 occasion, UE_ID represents the user identifier, Ns represents the third number, N represents the second number, mod represents the modulo operation, floor represents the floor operation.

[0120] Since the second paging occasion is calculated based on the system frame number, the system frame can be located outside the cell coverage time, and therefore the second paging occasion can also be located outside the cell coverage time. If the second paging occasion is located outside the cell coverage time, the terminal device can determine the index of the first paging occasion in the first system frame according to the aforementioned formula (3). The terminal device receives the paging message at the first paging occasion.

[0121] Embodiment 4, the network device configures the terminal device with the distribution of the cell coverage time or the first system frame through the first information.

[0122] For details, please refer to Figure 6 , Figure 6 A communication method flow is shown in this embodiment.

[0123] In step 601, the network device sends the first information to the terminal device. The first information is used to determine the distribution of the cell coverage time or to determine the first system frame.

[0124] In one specific embodiment, the first information includes a discontinuous coverage pattern parameter, and the discontinuous coverage pattern parameter includes one or more of the following: a time domain starting position of a coverage time window, a length of the coverage time window, and a period of the coverage time window.

[0125] The embodiment configures the distribution of the cell coverage time for the terminal device through the non-continuous coverage pattern parameters.

[0126] In another specific embodiment, the first information includes one or more coefficients: a first coefficient, a second coefficient, and a third coefficient, which are used to determine the first system frame located in the cell coverage time.

[0127] That is, the network device configures one or more coefficients for the terminal device, and the terminal device can determine the location of the first system frame according to the one or more coefficients.

[0128] Specifically, the system frame number SFN of each of the first system frames satisfies any of the following formulas:

[0129] SFN mod X = i; (6)

[0130] SFN mod X = i, i+1, …, i+N, (7)

[0131] Wherein, 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 one periodically distributed system frame; and formula (7) indicates that the first system frame is a continuously N+1 periodically distributed system frames.

[0132] The application also discloses an embodiment of determining the first paging occasion according to the second parameter. For details, please refer to embodiment 5.

[0133] Embodiment 5, the terminal device acquires the second parameter, and calculates the location of the first paging occasion according to the second parameter.

[0134] For details, please refer to Figure 7 , Figure 7 A communication method flow in the embodiment is shown.

[0135] In step 701, the terminal device acquires the second parameter. The second parameter can include one or more of the following: a user identifier, a fourth number of cell coverage time windows in a single paging cycle, and a fifth number of paging occasions in each cell coverage time window.

[0136] Specifically, the fourth number represents the number of cell coverage time windows in each paging cycle. For details, please refer to Figure 8 There are three coverage time windows in a single paging cycle, and the fourth number is 3. The terminal device can acquire the fourth number in the second parameter through the method in the foregoing embodiment 4.

[0137] Specifically, the fifth number represents the number of paging occasions in each cell coverage time window. For details, please refer to Figure 3 There are 3 paging occasions in each cell coverage time window, and the fifth number is 3.

[0138] In step 702, the terminal device calculates the position of the first paging occasion according to the second parameter. The first paging occasion is located in a cell coverage time window.

[0139] Specifically, the terminal device can first determine a cell coverage time window according to the fourth quantity, and then determine the first paging occasion in the cell coverage time window.

[0140] In one specific embodiment, the terminal device calculates an index of a first coverage time window in which the first paging occasion is located according to the user identifier and the fourth quantity. The terminal device calculates a paging occasion index of the first paging occasion in the first coverage time window according to the user identifier and the fifth quantity. The paging occasion index is obtained by numbering all paging occasions in the first coverage time window in time sequence.

[0141] Specifically, the terminal device can calculate the index of the first coverage time window using the following formula:

[0142] UE-ID mod M = m, (8)

[0143] Wherein, UE_ID represents the user identifier, M represents the fourth quantity, and m represents the index of the first coverage time window.

[0144] Specifically, the terminal device can calculate the paging occasion index of the first paging occasion using the following formula:

[0145] UE-ID mod N’ = n, (9)

[0146] Wherein, UE_ID represents the user identifier, N’ represents the fifth quantity, and n represents the paging occasion index of the first paging occasion.

[0147] In step 703, the terminal device receives the paging message at the first paging occasion.

[0148] The embodiments of the present application provide a new way of determining the first paging occasion by using the second parameter to determine the first paging occasion, and the required second parameter is less, the calculation formula is simple, and the complexity of the terminal device is reduced.

[0149] Embodiment 6, the network device configures the terminal device with information of a listening time (Paging Monitoring Occasion, PMO) through second information.

[0150] Specifically, refer to Figure 9 , Figure 9 A communication method flow is shown in the embodiment.

[0151] In step 901, the network device sends second information to the terminal device. The second information includes a starting position of a first Physical Downlink Control Channel (PDCCH) PMO in each wave position group service duration, each wave position in the wave position group corresponds to a synchronization signal block, and each cell coverage time window contains at least one wave position group service duration.

[0152] For reference Figure 8 In the first coverage time window, the cell coverage time window contains 4 wave position group service durations, each wave position group includes 1 wave position, and each wave position corresponds to a synchronization signal block. Each wave position group service duration includes 3 PMOs. The second information includes a starting position of a first PMO in the 3 PMOs.

[0153] For reference Figure 10 In the first coverage time window, the cell coverage time window contains 4 wave position group service durations, each wave position group includes 2 wave positions, and each wave position corresponds to a synchronization signal block. Each wave position group service duration includes 4 PMOs. The second information includes a starting position of a first PMO in the 4 PMOs.

[0154] For the terminal device, the corresponding PMO in each wave position group service duration for each paging occasion can be determined according to the second information.

[0155] Specifically, each paging occasion corresponds to K consecutive PMOs in each wave position group service duration, K represents the number of synchronization signal blocks corresponding to each wave position group, and the K PMOs correspond one-to-one to the K synchronization signal blocks corresponding to each wave position group.

[0156] For reference Figure 8 When the number K of synchronization signal blocks corresponding to each wave position group is 1, each paging occasion corresponds to 1 PMO in each wave position group service duration. Taking paging occasion PO1 as an example, the paging occasion PO1 corresponds to 1 PMO (i.e., PMO1) in the first wave position group service duration, and the PMO corresponds to synchronization signal block SSB1; correspondingly, the paging occasion PO1 corresponds to 1 PMO (i.e., PMO2) in the second wave position group service duration, and the PMO corresponds to synchronization signal block SSB2; the paging occasion PO1 corresponds to 1 PMO (i.e., PMO3) in the third wave position group service duration, and the PMO corresponds to synchronization signal block SSB3; and the paging occasion PO1 corresponds to 1 PMO (i.e., PMO4) in the fourth wave position group service duration, and the PMO corresponds to synchronization signal block SSB4.

[0157] For reference Figure 10, the number K of the synchronization signal blocks corresponding to each wave position group is 2, then each paging occasion corresponds to 2 PMOs in each wave position group service duration. Among them, the first wave position group corresponds to synchronization signal blocks SSB1 and SSB2, the second wave position group corresponds to synchronization signal blocks SSB3 and SSB4, the third wave position group corresponds to synchronization signal blocks SSB5 and SSB6, and the fourth wave position group corresponds to synchronization signal blocks SSB7 and SSB8. Taking paging occasion PO1 as an example, paging occasion PO1 corresponds to 2 PMOs (namely PMO1 and PMO2) in the first wave position group service duration, and the 2 PMOs correspond to synchronization signal blocks SSB1 and SSB2; correspondingly, paging occasion PO1 corresponds to 2 PMOs (namely PMO3 and PMO4) in the second wave position group service duration, and the 2 PMOs correspond to synchronization signal blocks SSB3 and SSB4; paging occasion PO1 corresponds to 2 PMOs (namely PMO5 and PMO6) in the third wave position group service duration, and the 2 PMOs correspond to synchronization signal blocks SSB5 and SSB6; paging occasion PO1 corresponds to 2 PMOs (namely PMO7 and PMO8) in the fourth wave position group service duration, and the 2 PMOs correspond to synchronization signal blocks SSB7 and SSB8.

[0158] Further, the PMOs corresponding to each paging occasion in the same wave position group service duration are continuous in the time domain.

[0159] For details, please refer to Figure 10 , the number of paging occasions is 2, and each paging occasion corresponds to 2 PMOs continuous in the time domain in each wave position group service duration. Taking the first as an example, paging occasion PO1 corresponds to the first group of PMOs1 and PMO2 continuous in the time domain; correspondingly, paging occasion PO2 corresponds to the second group of PMOs1 and PMO2 continuous in the time domain.

[0160] The embodiment of the application provides a mapping mode of the PMO corresponding to the paging occasion in the non-continuous coverage scene, realizes the mapping between the paging occasion and the PMO in the coverage time, and further guarantees the successful reception of the paging message.
