[0053] In the above embodiment, several methods for determining the target cell are provided, which are easy to implement.

[0054] In conjunction with some embodiments of the first aspect, in some embodiments, determining the target cell according to the identifier of the terminal and the number of first cells includes determining in at least one of the following ways:

[0055] Cell-index = UE_ID mod M;

[0056] Cell-index=Floor(UE_ID / N)mod M;

[0057] Cell-index=Floor(UE_ID / N / Ns)mod M;

[0058] Cell-index is the cell index of the target cell; UE_ID is the terminal identifier; M is the number of first cells; N is the number of paging frames of all first cells in a discontinuous reception DRX cycle; Ns is the number of paging occasions PO of all first cells in a DRX cycle.

[0059] In the above embodiment, the cell index of the target cell is determined in this manner. In this manner, the terminal and the network device do not need to perform signaling interaction to inform the terminal of the target cell to monitor the paging message, thereby saving signaling overhead.

[0060] In conjunction with some embodiments of the first aspect, in some embodiments, determining the target cell according to the terminal identifier and the number of paging frames includes:

[0061] Determine the target frame according to the terminal identifier and the number of paging frames;

[0062] The target cell is determined according to the first cell to which the target frame belongs; wherein the target frame is used for the target cell to send a paging DCI.

[0063] Based on the above solution, the target cell for the terminal to receive the paging message is indirectly determined by determining the target frame, so the target frame and the target cell are determined simultaneously through one process.

[0064] In conjunction with some embodiments of the first aspect, in some embodiments, determining the target frame according to the terminal identifier and the number of paging frames includes at least one of the following:

[0065] Frame-index = UE_ID mod K;

[0067] Frame-index is the frame number of the target frame; UE_ID is the identifier of the terminal; M is the number of first cells; and K is the number of paging frames of all first cells in one DRX cycle.

[0068] In the above embodiment, the target frame is determined based on the above formula, and the terminal and the network device do not need to perform signaling interaction to inform the terminal of the target frame to monitor the paging message, thereby saving signaling overhead.

[0069] In conjunction with some embodiments of the first aspect, in some embodiments,

[0071] First district.

[0072] In the above embodiment, the paging frames in the same DRX cycle of multiple first cells associated with one second cell are sequentially numbered, so both the terminal and the network device can easily know the target cell according to the paging frame number.

[0073] In conjunction with some embodiments of the first aspect, in some embodiments,

[0074] The paging frame sequence numbers of all first cells in the same DRX cycle include at least one of the following:

[0075] Sequentially number the paging frames of all first cells in the same DRX cycle according to the cell indexes of all first cells from largest to smallest or from smallest to largest;

[0077] The paging frames of all first cells in the same DRX cycle are sequentially numbered from high to low or from low to high according to the frequency domain positions of the paging frames.

[0078] In the above embodiment, a method for numbering paging frames on multiple first cells is provided, which has the characteristic of being simple to implement.

[0079] With reference to some embodiments of the first aspect, in some embodiments, the index of the target cell is the first index or the second index;

[0080] The first index is an index obtained based on the second cell and all cell numbers of the first category associated with the second cell; the second index is an index obtained based on the first cell number.

[0081] Based on the above solution, the cell index of the target cell can be the first index or the second index, and the cell index to be used can be flexibly selected as needed.

[0082] In conjunction with some embodiments of the first aspect, in some embodiments, determining the target cell according to the terminal identifier and the number of paging occasions includes:

[0083] Determine the target opportunity based on the terminal identifier and the number of paging opportunities;

[0084] The target cell is determined according to the first cell to which the target opportunity belongs; the target opportunity is used for the target cell to send a paging DCI.

[0085] Based on the above scheme,

[0086] The timing number of the target timing is determined by at least one of the following methods:

[0087] UE_ID mod X;

[0088] Floor(UE_ID / M)mod X;

[0089] Floor(UE_ID / M / N)mod X;

[0090] Floor(UE_ID / K)mod X;

[0091] UE_ID is the identifier of the terminal; M is the number of first cells; X is the number of paging opportunities of all first cells in one DRX cycle; K is the number of paging frames in one DRX cycle.

[0092] In the above embodiment, the timing number of the target timing is determined in such a way that the terminal and the network device do not need to perform signaling interaction to inform the terminal of the target timing for monitoring paging messages, thereby saving signaling overhead.

[0093] In combination with some embodiments of the first aspect, in some embodiments, paging occasions in the same DRX cycle on multiple first cells are sequentially numbered.

[0094] Based on the above approach, the paging occasions of multiple first cells in the same DRX cycle are sequentially numbered, so that the subsequent terminal can simply determine the target cell for monitoring the paging message according to the paging occasion.

[0095] In conjunction with some embodiments of the first aspect, in some embodiments, the sequential numbering of paging occasions in the same DRX cycle on multiple first cells includes:

[0096] Sequentially number the paging occasions of the multiple cells in the same DRX cycle according to the cell indices of the multiple first cells from largest to smallest or from smallest to largest;

[0097] Sequentially numbering the paging occasions of the multiple first cells in the same DRX cycle from front to back or from back to front according to the time domain positions of the paging frames;

[0098] The paging occasions of the multiple first cells in the same DRX cycle are sequentially numbered from high to low or from low to high according to the frequency domain positions of the paging frames.

[0099] Based on the above method, several implementation methods for numbering paging occasions of multiple first cells in the same DRX cycle are provided, which are simple to implement.

[0100] With reference to some embodiments of the first aspect, in some embodiments, the cell index is the first index or the second index;

[0101] The first index is an index of each cell of the first category associated with a second cell;

[0102] The second index is an index of a first cell associated with a second cell.

[0103] Based on the above manner, the cell index may be a cell index or an index of the first cell, so that the cell index used to determine the target cell may be flexibly selected as needed.

[0104] In conjunction with some embodiments of the first aspect, in some embodiments, the method further includes:

[0105] The network device sends first information to the terminal, where the first information indicates at least one of the following:

[0106] The terminal receives the target cell of the paging DCI;

[0107] The terminal receives a paging frame of a paging DCI;

[0108] The paging opportunity when the terminal receives the paging DCI;

[0109] The paging group or paging subgroup to which the terminal belongs; the paging group is associated with the cell, paging frame or paging opportunity in which the terminal receives downlink control information DCI; the paging subgroup is associated with the cell, paging frame or paging opportunity in which the terminal receives downlink control information DCI; the paging DCI is used to schedule paging messages.

[0110] Based on the above approach, the network device can send the first information so that the terminal determines the cell, paging frame, paging opportunity and / or paging group or paging subgroup to monitor the paging message according to the received first information.

[0111] With reference to some embodiments of the first aspect, in some embodiments, sending the first information includes:

[0112] A first signal carrying first information is sent to a first transceiver of a terminal, where the first signal is used to wake up a second transceiver of the terminal; the power consumption of the second transceiver is higher than that of the first transceiver.

[0113] Based on the above method, the first signal carries the first information, which can be used to wake up the second transceiver of the terminal in a low power consumption state. In this way, no additional message signaling is required to send the first information, saving the number of messages and / or signaling overhead.

[0114] In combination with some embodiments of the first aspect, in some embodiments, multiple first cells associated with a second cell share a set of paging configurations, or the paging configurations of multiple first cells associated with a second cell are associated with each other, or the paging configurations of multiple first cells associated with a second cell are independent of each other.

[0115] Based on the above manner, the first information may include a paging configuration. There are multiple forms of the paging configuration, and the required paging configuration can be flexibly selected as needed later.

[0116] In conjunction with some embodiments of the first aspect, in some embodiments, when the multiple first cells include the second cell and a cell of the first type associated with the second cell, the paging configurations of the multiple first cells are associated with each other and include at least one of the following:

[0119] The paging frame of the adjacent third cell has a first step length in the time domain, and the paging frame of the first third cell has a second step length in the time domain relative to the paging frame of the second cell;

[0120] The third cell is a cell of the first type among the multiple first cells. Based on the above method, several implementation methods for associating the paging configurations of multiple first cells are provided, which have the characteristic of being simple to implement.

[0121] In conjunction with some embodiments of the first aspect, in some embodiments, sending a paging message in a first-category cell includes:

[0122] In the first type of cells, beam scanning is used to send paging downlink control information DCI; the paging DCI is used to schedule paging messages.

[0123] When the first type of cell uses beam scanning to send paging DCI, this can be applicable to the scenario where the first type of cell uses beam communication.

[0124] In combination with some embodiments of the first aspect, in some embodiments, the beam configuration for sending paging DCI using beam scanning on the first type of cell is the same as the beam configuration for sending SSB and / or system information block SIB using beam scanning on the second cell.

[0125] Based on the above method, since the first type of cell does not send SSB and / or SIB, when the first type of cell sends paging DCI, the paging DCI can be sent according to the beam configuration of SSB and / or SIB on the second cell, which has the characteristic of simple implementation. In this way, on the one hand, the network equipment can realize the sending of SSB and / or SIB and the sending of paging DCI on the first type of cell through a set of beam configurations. On the other hand, the terminal can receive a beam configuration, and know the method of monitoring paging DCI in the first type of cell while knowing that SSB and / or SIB are received in the second cell, which has the characteristic of low signaling overhead.

[0128] In conjunction with some embodiments of the first aspect, in some embodiments, the cell configuration sent by the second cell may include a configuration of whether the first-category cell sends a paging message. If the first-category cell can send a paging message, the paging capacity of the communication system can be increased, and the first-category cell can be used to share the paging load of the second cell.

[0129] In conjunction with some embodiments of the second aspect, in some embodiments,

[0139] Timing configuration, used for synchronization of terminals in cells of the first category;

[0140] The coverage configuration is used by the terminal to determine the coverage range of the first type of cell.

[0141] Based on the above manner, there are many cell configurations of the first type of cell sent by the second cell. The above are examples of cell configurations, and specific implementation is not limited to the above examples.

[0142] In combination with some embodiments of the first aspect, in some embodiments, the coverage of the first type of cell and the second cell is the same, or the first type of cell and the second cell have the same tracking area code TAC, or the first type of cell and the second cell share the same site, or the carriers used by the first type of cell and the second cell belong to the same broadband carrier, or the first type of cell and the second cell have a neighboring cell relationship.

[0143] Based on the above manner, the first type of cell and the second cell have the above relationship, so that the first type of cell sending the paging message can share the paging load of the second cell, thereby improving the paging capacity of the entire communication system.

[0144] In combination with some embodiments of the first aspect, in some embodiments, the default configuration of the first type of cell is the same as the cell configuration of the second cell.

[0145] Based on the above approach, the sending of cell configurations for cells of the first category can be reduced, thereby reducing signaling overhead.

[0235] FIG1A is a schematic diagram showing the architecture of a communication system according to an embodiment of the present disclosure.

[0236] As shown in Figure 1A, a communication system 100 includes a terminal 101 and a network device 102. The network device 102 may include an access network device and a core network device.

[0237] In some embodiments, the terminal 101 includes, for example, a mobile phone, a wearable device, an Internet of Things device, a car with communication function, a smart car, a tablet computer, a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, and at least one of a wireless terminal device in a smart home, but is not limited thereto.

[0238] In some embodiments, the terminal is also referred to as User Equipment (UE).

[0239] In some embodiments, the access network device may be, for example, a node or device that accesses a terminal to a wireless network. The access network device may include an evolved NodeB (eNB), a next generation evolved NodeB (ng-eNB), a next generation NodeB (gNB), a node B (NB), a home node B (HNB), a home evolved nodeB (HeNB), a wireless backhaul device, a radio network controller (RNC), a base station controller (BSC), a base transceiver station (BTS), a base band unit (BBU), a mobile switching center, a base station in a 6G communication system, an open base station (Open RAN), a cloud base station (Cloud RAN), a base station in other communication systems, and at least one of an access node in a Wi-Fi system, but is not limited thereto.

[0240] In some embodiments, the technical approach of the present disclosure may be applicable to the Open RAN architecture. In this case, the interfaces between or within the access network devices involved in the embodiments of the present disclosure may become internal interfaces of the Open RAN, and the processes and information interactions between these internal interfaces may be implemented through software or programs.

[0241] In some embodiments, the access network device can be composed of a centralized unit (CU) and a distributed unit (DU), where the CU can also be called a control unit. The CU-DU structure can be used to split the protocol layer of the access network device, with the functions of some protocol layers centrally controlled by the CU, and the functions of the remaining part or all of the protocol layers distributed in the DU, which is centrally controlled by the CU, but is not limited to this.

[0242] In some embodiments, the core network device may be a single device including a first network element, or may be a plurality of devices or a group of devices, each including a first network element. The network element may be virtual or physical. The core network may include, for example, at least one of an Evolved Packet Core (EPC), a 5G Core Network (5GCN), and a Next Generation Core (NGC).

[0243] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical approach of the embodiment of the present disclosure, and does not constitute a limitation on the technical approach provided by the embodiment of the present disclosure. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical approach provided by the embodiment of the present disclosure is also applicable to similar technical problems.

[0244] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1A , or a portion thereof, but are not limited thereto. The entities shown in FIG1A are illustrative only. The communication system may include all or part of the entities shown in FIG1A , or may include other entities other than those shown in FIG1A . The number and form of the entities may be arbitrary. The connection relationship between the entities is illustrative only.

[0245] The embodiments of the present disclosure may be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G New Radio (NR), Future Radio Access (FRA), New-Radio Access Technology (RAT), New Radio (NR), New Radio Access (NX), Future Generation Radio Access (FX), Global System for Mobile Communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.17 (WiMAX (registered trademark)), IEEE 802.18 (WiMAX (registered trademark)), IEEE 802.19 (WiMAX (registered trademark)), IEEE 802.20 (WiMAX (registered trademark)), IEEE 802.21 (WiMAX (registered trademark)), IEEE 802.22 (WiMAX (registered trademark)), IEEE 802.23 (WiMAX (registered trademark)), IEEE 802.24 (WiMAX (registered trademark)), IEEE 802.25 (WiMAX (registered trademark)), IEEE 802.26 (WiMAX (registered trademark)), IEEE 802.27 (WiMAX (registered trademark)), IEEE 802.28 (WiMAX (registered trademark)), IEEE 802.29 (WiMAX (registered trademark)), IEEE 802.30 (WiMAX (registered trademark)), IEEE 802.31 (WiMAX (registered trademark)), IEEE 802.32 (WiMAX (registered trademark)), IEEE 802.33 (WiMAX (registered trademark)), 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X), systems utilizing other paging methods, and next-generation systems based on these. Furthermore, a combination of multiple systems (e.g., a combination of LTE or LTE-A with 5G) may also be employed.

[0246] As shown in Figure 1B, the evolution from a regular cell to an SSB / SIB-less cell is shown. Regular cells will send SSBs and / or SIBs, etc. For example, regular cells will send SIB1. The SIB1 can be configured with a random access channel (RACH), which can be used for random access of terminals. Regular cells will send paging messages (paging). The paging messages can be used to page terminals in idle and / or inactive states. In order to achieve network energy saving, after a regular cell evolves to an SSB / SIB-less cell, the SSB / SIB-less cell may not send SSBs or SIBs. And the RACH of the SSB / SIB-less cell can be configured by the first type of cell. In some cases, in order to further save power consumption of the SSB / SIB-less cell, the SSB / SIB-less cell will not send a paging message. In this way, all paging messages will be sent by regular cells. Considering that there will be more and more terminals in the future network, there may be a situation where the paging capacity is insufficient due to the regular cells sending paging messages alone, or it may cause the regular cells to have a heavy paging load and / or the paging capacity of the entire communication system to be limited.

[0247] FIG2A is an interactive diagram of a paging method according to an embodiment of the present disclosure. As shown in FIG2A , the embodiment of the present disclosure relates to a paging method for a communication system 100, the method comprising:

[0248] S2101: The network device sends the cell configuration of the first type of cell to the terminal in the second cell.

[0249] In some embodiments, the network device may be an access network device. The access network device may be an evolved base station and / or a next generation base station.

[0250] In some embodiments, the second cell may be a regular cell.

[0251] In some embodiments, the second cell may transmit SSBs and / or SIBs. For example, the second cell will transmit SSBs and / or SIBs.

[0252] In some embodiments, the first type of cell may be a cell that does not transmit an SSB and / or an SIB. For example, the first type of cell may be a cell that does not transmit an SSB and / or an SIB.

[0253] In some embodiments, the network device transmits a SIB including the cell configuration in the second cell.

[0254] In some embodiments, the network device multicasts the SIB containing the cell configuration in the second cell.

[0255] In some other embodiments, the network device unicasts a radio resource control (RRC) message including cell configuration in the second cell.

[0256] In some embodiments, part or all of the cell configurations of the cells of the first category may be sent by the second cell.

[0257] In some embodiments, the second cell and the first type of cell satisfy the following coverage relationship:

[0258] The second cell has the same coverage as a cell of the first type associated with the second cell, or,

[0259] The second cell and the cell of the first type associated with the second cell have the same Tracking Area Code (TAC), or,

[0260] The second cell is co-located with a cell of the first type associated with the second cell, or,

[0261] The carrier used by the second cell and the cell of the first type associated with the second cell belongs to the same broadband carrier, or,

[0262] The second cell and a cell of the first type associated with the second cell have a neighboring cell relationship.

[0263] In some embodiments, the cells of the first category may be SSB / SIB1-less cells.

[0264] As shown in Figure 3A, SSB / SIB1-deficient cell 3 is a cell with the same coverage as a regular cell. SSB / SIB1-deficient cell 2 is a cell with overlapping coverage with a regular cell, and SSB / SIB1-deficient cell 3 is completely within the coverage of the regular cell. SSB / SIB1-deficient cell 1 has overlapping coverage with a regular cell, and some areas of SSB / SIB1-deficient cell 1 are outside the coverage of the regular cell.

[0265] In some embodiments, the cell configuration can at least be used by the terminal to determine whether the first type of cell sends a paging message.

[0266] Exemplarily, the cell configuration may indicate whether the first type of cell is capable of sending a paging message, or whether the first type of cell shares the paging load of the second cell.

[0267] Preferably, SSB / SIB1 missing cell 3 can be selected as the first type of cell to send the paging message. In this case, the first type of cell and the second type of cell have the same coverage, so it can be ensured that all terminals located in the regular cell can be paged, thereby improving the paging capacity of the system.

[0268] In some embodiments, the paging configurations of multiple first cells may be independent of each other or may be associated with each other.

[0269] If the paging configurations of multiple first cells are independent of each other, the configuration related to the sending of the paging message of each first cell can be flexibly configured as needed.

[0270] In some embodiments, the cell configuration includes at least one of the following:

[0271] The index of the cell of the first category;

[0272] The identification of the first type of cell;

[0273] A paging indication, used to indicate whether the first type of cell sends a paging message;

[0274] Paging configuration, used for sending paging messages in cells of the first category;

[0275] Beam indication, used to indicate whether the first type of cell uses beam communication;

[0276] Beam configuration, used to configure the beam of the first type of cell;

[0277] Frequency configuration, used to indicate frequency usage of cells of the first category;

[0278] Access configuration, used for access to cells of the first category;

[0279] Timing configuration, used for synchronization of terminals in cells of the first category;

[0280] Coverage configuration is used by a terminal to determine the coverage of a first-category cell. As shown in Figure 3A, there may be multiple first-category cells that overlap with a second cell. To facilitate management of the first-category cells, the first-category cells may be numbered to obtain an index of the first-category cells. Subsequent cell configuration can be performed based on the index of the first-category cells, thereby saving bit overhead.

[0281] In some embodiments, the cell index and cell identifier of a first-category cell may be carried in the cell configuration, facilitating subsequent communication between the first-category cell and / or the second cell and the terminal based on the cell index of the first-category cell. This reduces signaling overhead compared to communication using the cell identifier. In this way, the cell identifiers of the first-category cells associated with different second cells may be different, but the cell index may be the same.

[0282] In some embodiments, cell configuration may also be performed based on a cell identity. For example, the cell configuration may include, but is not limited to, various types of cell identities (IDs). The cell identity may be a physical layer cell identity, a logical cell identity, and / or a high-layer cell identity. The high-layer cell identity may be used for high-layer communications above the physical layer of the terminal, such as the MAC layer and / or the RRC layer. The high-layer identity may be referred to as a cell identity.

[0283] Exemplarily, the identifier of the first type of cell is different from the identifier of the second cell, that is, the first type of cell has an independent cell identifier relative to the second cell.

[0284] In some embodiments, the length of the cell identifier may be greater than the length of the cell index, so that using the cell index for communication can save signaling overhead.

[0285] In some embodiments, a paging indication may be used to indicate whether a cell corresponding to the first category sends a paging message. In other words, the paging indication may indicate whether a cell corresponding to the first category serves as a primary cell. The primary cell may be a cell that sends a paging message. The paging message may be used to page idle terminals and / or inactive terminals.

[0286] In some embodiments, the paging indication is further used to indicate whether the terminal should share part of the paging load of the second cell to the cells of the first category.

[0287] In some embodiments, the cell configuration may include a paging indication, which indicates to the terminal via the paging indication whether one or more second cells associated with a second cell can be used as cells for sending a paging message.

[0288] In other embodiments, the cell configuration of the first type of cell may not include a paging indication, and the terminal and the network device may implicitly indicate whether a first type of cell sends a paging message based on the protocol agreement and / or whether the coverage range of the first type of cell is the same as that of the second cell.

[0289] For example, the terminal and the network device both agree to determine a first-category cell having the same coverage area as the second cell as the first-category cell to which the paging message is sent.

[0290] In some embodiments, the paging configuration may correspond to a first type of cell acting on the first cell. The paging configuration may include, but is not limited to, at least one of the following: configuration of a paging frame and / or configuration of a paging occasion. These configurations may include configuration of time-frequency domain resources.

[0291] Exemplarily, multiple first cells associated with one second cell share a set of paging configurations, or the paging configurations of multiple first cells associated with one second cell are associated with each other, or the paging configurations of multiple first cells associated with one second cell are independent of each other.

[0292] In some embodiments, when the multiple first cells include the second cell and a cell of the first type associated with the second cell, the paging configurations of the multiple first cells are associated with each other and include at least one of the following:

[0293] The paging frame of the third cell has an offset in the time domain relative to the paging frame of the second cell;

[0294] The paging frames of the adjacent third cells have a first interval in the time domain, and the paging frame of the first of the third cells has a second interval in the time domain relative to the paging frame of the second cell;

[0295] The paging frame of the adjacent third cell has a first step length in the time domain, and the paging frame of the first third cell has a second step length in the time domain relative to the paging frame of the second cell;

[0296] The third cell is a cell of the first type among the multiple first cells.

[0297] In some embodiments, the third cell is a cell of the first type among the first cells.

[0298] The adjacent third cell may be a cell whose cell index is adjacent to the first cell.

[0299] In some embodiments, the first interval may be equal to the second interval. In other embodiments, the first interval may not be equal to the second interval.

[0300] By setting the first interval and / or the second interval, the signaling overhead of the paging configuration can be reduced.

[0301] In some embodiments, the first step length may be equal to the second step length. In other embodiments, the second step length may not be equal to the first step length.

[0302] By setting the first step length and / or the second step length, the signaling overhead of the paging configuration can be reduced.

[0303] That is, the paging configurations of the multiple first cells are associated with each other in at least one of the following aspects:

[0304] In the case where the first cell includes the second cell, the paging frame of the cell of the first type as the first cell has an offset in the time domain relative to the paging frame of the second cell, or,

[0305] In the case where the first cell includes the second cell, the paging frame of the first first-category cell of the first cell has an interval in the time domain relative to the paging frame of the second cell, and the paging frames of two adjacent first-category cells have an interval in the time domain, or,

[0306] When the first cell includes the second cell, the paging frame of the first first-category cell of the first cell has a step length in the time domain relative to the paging frame of the second cell, and the paging frames of two adjacent first-category cells have a step length in the time domain.

[0307] Exemplarily, the paging configurations of multiple first cells associated with one second cell are associated with each other in at least one of the following aspects:

[0308] The paging frames of the cells of the first category have an offset in the time domain relative to the paging frames of the second cell, or,

[0309] The paging frame of the first cell of the first category is spaced apart from the paging frame of the second cell in the time domain, and the paging frames of two adjacent cells of the first category are spaced apart in the time domain, or,

[0310] The paging frame of the first cell of the first category has a step length relative to the paging frame of the second cell in the time domain, and the paging frames of two adjacent second cells have a step length in the time domain.

[0311] In some embodiments, the paging frame offsets of different second cells relative to the first-category cells may be the same or different. For example, if the mth paging frame of the nth first-category cell and the second cell in a DRX cycle has the mth offset, then the paging frames of the nth first-category cell and the second cell in the same time domain order within the DRX cycle all have the mth offset.

[0312] In some other embodiments, there is a preset interval from large to small or from small to large according to the cell index, so that the paging frame of the nth first-category cell has n intervals relative to the paging frame of the second cell.

[0313] FIG3B is a schematic diagram showing the frame numbering of paging frames of multiple first cells. The cell index of cell x is smaller than the cell index of cell y, and the cell index of cell y is smaller than the cell index of cell z. When the paging frames are numbered from small to large according to the cell index, and the paging frames of a single cell are numbered from front to back in the time domain, the frame numbering of the paging frames shown in FIG3B is obtained. The paging frames of cell x include: paging frames (PF) 1, PF2, and PF3, where 1, 2, and 3 are all frame numbers. The paging frames of cell y are numbered from 4 to 6, and the frames of cell z are numbered from 7 to 9.

[0314] Figure 3C is a schematic diagram of the frame numbering of paging frames of multiple first cells. The cell index of cell x is smaller than the cell index of cell y, and the cell index of cell y is smaller than the cell index of cell z. When the paging frames are numbered from small to large according to the cell index, and the paging frames of all first cells are numbered from front to back in the time domain, the frame numbering of the paging frames shown in Figure 3B will be obtained. The paging frames of cell x include: paging frames (PF) 1, PF4, and PF7, where 1, 4, and 7 are all frame numbers. The paging frames of cell y are numbered 2, 5, and 8; the paging frames of cell z are numbered 3, 6, and 9.

[0315] It can be seen that as shown in Figures 3B and 3C, there are multiple paging occasions (POs) in a paging frame. For example, a paging frame may include three POs, namely PO1, PO2 and PO3. Figure 3D is a schematic diagram of the frame numbering of paging frames of multiple first cells. Cell y and cell z are both first cells. The anchor cell is the second cell. Cell y and cell z are both cells of the first type. Referring to Figure 3D, the anchor cell has multiple PFs in one DRX cycle. The PF1 of cell y has a certain offset relative to the PF1 of the anchor cell. Of course, it is also possible to sort from large to small or from small to large according to the index number, and the FPs with the same sorting in one DRX cycle have a specified step size or interval.

[0316] In some embodiments, the paging configuration association may be reflected not only in the time domain configuration of the paging frame, but also in the time domain configuration of the paging opportunity.

[0317] In some embodiments, the beam indication may be used to indicate whether the first type of cell serving as the first cell adopts beam communication, or whether a paging message is sent using beam scanning.

[0318] In other embodiments, if the first type of cell uses beam communication, there may be corresponding beam configuration.

[0319] In some embodiments, the beam configuration may include: a static beam configuration, a semi-persistent beam configuration and / or a dynamic beam configuration.

[0320] Exemplarily, the beam configuration may be used to indicate the beam scanning period, the number of beams transmitted by a cell, and / or the transmission direction of each beam, etc.

[0321] In some embodiments, the frequency configuration may be used to indicate a frequency layer, a frequency band, a bandwidth part (BandWidth Part, BWP), and a frequency range (Frequency Range, FR) used by cells of the first category.

[0322] In some embodiments, the frequency configuration may indicate the frequency configuration for sending paging messages by cells of the first category.

[0323] In some embodiments, the access configuration may include, but is not limited to, at least one of the following:

[0324] Random access configuration of a cell of the first category, exemplarily, configuration of RACH and / or random access preamble;

[0325] Initial access configuration of cells of the first category;

[0326] Condition configuration for accessing a cell of the first category, illustratively, configuration of a threshold value for accessing a cell of the first category;

[0327] Configuration of conditions for leaving a cell of the first category.

[0328] Timing configuration can be used for synchronization between the terminal and the first type of cell. The timing configuration may include but is not limited to uplink timing configuration and / or downlink timing configuration.

[0329] Exemplarily, the uplink timing configuration may be used for uplink synchronization between the terminal and a cell of the first category.

[0330] As another example, the downlink timing configuration may be used for downlink synchronization between the terminal and a cell of the first category.

[0331] In some embodiments, the timing configuration may also include a timing advance (TA) configuration for uplink communications of the terminal. In some embodiments, the first-category cell configuration transmitted by the second cell also includes a coverage configuration for the first-category cell. The coverage configuration may be used by the terminal to determine the coverage range of the first-category cell and / or to determine whether to enter or leave the coverage range of the first-category cell.

[0332] Exemplarily, the coverage configuration may include: using reference signal configuration sent by the first type of cell and / or the second cell. The terminal determines whether the terminal is within the coverage of the first type of cell by measuring the reference signal.

[0333] In some embodiments, the cell configuration may further include:

[0334] Reference signal configuration. The reference signal configuration is related to the first type of cell. Exemplarily, the reference signal configuration may include but is not limited to a DL reference signal configuration and / or a UL reference signal configuration.

[0335] Exemplarily, the reference signal may include but is not limited to various reference signals sent by the second cell for the terminal to determine whether to access the first type of cell, such as SSB set configuration, Channel State Information-Reference Signal (CSI-RS) set, etc.

[0336] In some embodiments, the cell configuration of the first type of cell further includes but is not limited to a slice configuration; the slice configuration may include slice identifiers supported by the first type of cell. Exemplarily, the slice configuration may include: a slice list of network slices supported by the first type of cell. The slice list carries a network slice identifier.

[0337] In some embodiments, the default configuration of the cells of the first category is the same as the cell configuration of the second cell.

[0338] For example, if the beam configuration of the first type of cell is default, the terminal may directly regard the beam configuration of the second cell as the beam configuration of the first type of cell.

[0339] S2102: The terminal and the network device respectively determine the target cell.

[0340] In some embodiments, the target cell network is the cell that sends the paging message.

[0341] In some embodiments, the target cell may include but is not limited to a cell of the first category and / or a second cell.

[0342] In some embodiments, the target cell may be determined in at least one of the following ways:

[0343] Determine a target cell according to the terminal identifier and the number of first cells, where the target cell is also used to send downlink control information (DCI) of the terminal;

[0344] Determine a target frame according to an identifier of the terminal and the number of paging frames of all first cells associated with a second cell in a discontinuous reception (DRX) cycle, and determine a target cell according to the target frame, where the target paging frame is used to send a paging DCI of the terminal in the target cell;

[0345] Determining a target timing according to an identifier of the terminal and the number of paging occasions of all first cells associated with a second cell in a discontinuous reception (DRX) cycle, and determining a target cell according to the target timing; the target timing is used to send a paging DCI of the terminal in the target cell;

[0346] Paging DCI is used to schedule paging messages; the number of first cells is the number of cells associated with one second cell and sending paging messages; the first cell includes cells of the first category and / or second cells; the cells of the first category have overlapping coverage with the second cell, and the second cell sends SSB and / or SIB.

[0347] In some embodiments, the cell index of the target cell is determined by at least one of the following methods:

[0348] UE_ID mod M;

[0349] Floor(UE_ID / N)mod M;

[0350] Floor(UE_ID / N / Ns)mod M;

[0351] UE_ID is the terminal identifier; M is the number of first cells associated with a second cell; N is the number of paging frames of all first cells associated with a second cell in a discontinuous reception DRX cycle; Ns is the number of paging occasions PO in a paging frame.

[0352] In some embodiments, the UE_ID may include but is not limited to the terminal's temporary mobile subscriber identity (TMSI). In some embodiments, the TMSI may further be a 5G globally unique temporary UE identity (5th Generation S-Temporary Mobile Subscriber Identity, 5G-S-TMSI).

[0353] Exemplarily, the UE_ID may be a UE identifier generated based on the TMSI. For example, the UE_ID is a calculation result based on the TMSI mod 1024 or 4096.

[0354] In some embodiments, Floor represents rounding down.

[0355] The terminal and the network device may determine the formula for calculating the cell index according to a protocol agreement or pre-configuration.

[0356] Of course, the above is only a calculation method for determining the cell index of the target cell, and the specific implementation is not limited to the above example.

[0357] In this case, after determining the target cell, the paging frame and / or paging opportunity for sending a paging message to the corresponding terminal can be determined based on relevant technologies and UE_ID.

[0358] In some embodiments, the time domain position of a paging frame (PF) may be determined according to the following functional relationship:

[0359] (SFN+PF_offset) mod T = n;

[0360] SFN is the super frame number.

[0361] PF_offset is the offset of PF;

[0362] T is the duration of the DRX cycle;

[0363] n is the number of the paging frame in a DRX cycle.

[0364] After determining the time domain position of each PF, the paging occasion (PO) for each UE to monitor the paging message can be determined according to the UE_ID. The PO for a specific terminal to monitor the paging message can be determined using the following function relationship:

[0365] i_s=floor(UE_ID / N)mod Ns;

[0366] i_s is the index of PO.

[0367] N is the number of paging frames in a DRX cycle.

[0368] Ns is the number of paging occasions in one DRX cycle.

[0369] In some embodiments, the frame number of the target frame is determined by at least one of the following methods:

[0370] UE_ID mod K;

[0371] Floor(UE_ID / M)mod K;

[0372] UE_ID is the identifier of the terminal; M is the number of first cells associated with one second cell; and K is the number of paging frames of all first cells associated with one second cell in one DRX cycle.

[0373] In this case, the sequence numbering of paging frames within a DRX cycle for a first cell associated with the same second cell—that is, the first cell associated with a second cell—shares the same set of numbers. Thus, multiple paging frames within a DRX cycle have different frame numbers, and each paging frame is mapped to a single first cell. Therefore, once the paging frame is determined, the target cell for sending the terminal's paging message is also determined.

[0374] In some embodiments, paging frames in the same DRX cycle on multiple first cells are sequentially numbered.

[0375] In some embodiments, the paging frame sequence numbers within the same DRX cycle on multiple first cells include at least one of the following:

[0376] Sequentially numbering the paging frames of the multiple first cells in the same DRX cycle according to the cell indices of the multiple first cells from largest to smallest or from smallest to largest;

[0377] Sequentially numbering the paging frames of the plurality of first cells in the same DRX cycle from front to back or from back to front according to the time domain positions of the paging frames;

[0378] The paging frames of the plurality of first cells in the same DRX cycle are sequentially numbered from high to low or from low to high according to the frequency domain positions of the paging frames.

[0379] In some embodiments, the cell indexes of the plurality of first cells may include a cell index of a cell of the first category associated with one second cell.

[0380] In some other embodiments, the cell indexes of the plurality of first cells may include: a cell index of a first cell associated with a second cell. That is, in some embodiments, the cell index is the first index or the second index;

[0381] The first index is an index of each cell of the first category associated with a second cell;

[0382] The second index is an index of a first cell associated with a second cell.

[0383] Exemplarily, the number of first cells associated with one second cell is less than or equal to the number of cells of the first category associated with one second cell.

[0384] In some embodiments, the paging frames are numbered from small to large according to the cell index, which can be understood as: first completing the numbering of the paging frames of the cell with a small cell index, and then numbering the paging frames of the cell with a large cell index.

[0385] In some embodiments, the paging frames are numbered from small to large according to the cell index, which can be understood as: first completing the numbering of the paging frames of the cell with a large cell index, and then numbering the paging frames of the cell with a small cell index.

[0386] In some embodiments, the paging frames are numbered according to their time domain positions, which can be understood as giving priority to the numbering of paging frames with earlier time domain positions. In this case, the paging frames with earlier time domain positions have smaller numbers.

[0387] In some embodiments, the paging frames are numbered according to the time domain positions, which can be understood as giving priority to the numbering of paging frames with later time domain positions. In this case, the paging frames with later time domain positions have smaller numbers.

[0388] In some embodiments, several methods may be combined to number the paging frames of multiple first cells associated with one second cell.

[0389] First, the paging frames with larger or smaller cell indexes are prioritized according to the cell index sorting, and at the same time, the paging frames are numbered from front to back or from back to front according to their positions in the time domain.

[0390] First, the paging frames with larger or smaller cell indices are prioritized according to the cell index sorting. At the same time, the paging frames are numbered according to the frequency domain positions from high to low or from low to high.

[0391] In summary, there are multiple ways to number paging frames, and the paging frames may be numbered in sequence based on a cell index, a time domain position, and / or a frequency domain position.

[0392] In some embodiments, paging occasions of multiple first cells associated with one second cell within a DRX cycle are sequentially numbered. It is understandable that multiple first cells associated with one second cell share a set of paging occasion numbers within a DRX cycle. Thus, one occasion number can be mapped to one cell, but different cells may be mapped to different paging occasions.

[0393] In some embodiments, the paging frame sequence numbers within the same DRX cycle on multiple first cells include at least one of the following:

[0394] Sequentially number the paging occasions of the multiple cells in the same DRX cycle according to the cell indices of the multiple first cells from largest to smallest or from smallest to largest;

[0395] Sequentially numbering the paging occasions of the multiple first cells in the same DRX cycle from front to back or from back to front according to the time domain positions of the paging frames;

[0396] The paging occasions of the multiple first cells in the same DRX cycle are sequentially numbered from high to low or from low to high according to the frequency domain positions of the paging frames.

[0397] Illustratively, the cell number may be the number of all second cells related to one second cell, or may be the number of the first cell.

[0398] For example, the number of the second cell may be 0, and the numbers of the SSB / SIB-less cells related to the second cell may gradually increase starting from 1.

[0399] In some embodiments, the paging occasions may be numbered sequentially from front to back or from back to front according to the time domain position.

[0400] In other embodiments, the paging occasions may be numbered sequentially from high to low or from low to high according to the frequency domain positions.

[0401] In some other embodiments, the paging occasions may be numbered in descending order or in ascending order according to the cell index.

[0402] In some embodiments, the cell indexes of the target cell and / or the first cell may both be the first index and / or the second index.

[0403] In some embodiments, the first index is an index obtained according to the second cell and all cell numbers of the first category associated with the second cell.

[0404] In some embodiments, the second index is an index obtained according to the first cell number.

[0405] In some embodiments, POs of the same order within time-domain aligned PFs on various first cells may be aligned in the time domain or may have a time offset in the time domain. For example, POs of the same order within time-domain aligned PFs on different first cells may have a specified offset, interval, or step size in the time domain based on the second cell.

[0406] S2103: Send paging DCI on the target cell.

[0407] In some embodiments, the paging DCI is sent on the cell of the first type and / or the second cell.

[0408] In some embodiments, the paging DCI is used for scheduling paging messages.

[0409] For example, the paging DCI includes a paging configuration indicating the paging message to be received by the terminal. The paging configuration can refer to any of the above embodiments.

[0410] In some embodiments, the target cell for sending the paging DCI is the cell where the terminal monitors the paging message.

[0411] In some embodiments, the paging DCI is sent on the target cell using a beam scanning method.

[0412] In some embodiments, when the target cell is a first type of cell and the paging DCI is sent using beam scanning, the paging DCI is sent using the beam configuration of the second cell to send SSB and / or SIB on the first type of cell.

[0413] In some embodiments, for example, the second cell uses beams in four directions, beams 1 to 4, to send SSB or SIB respectively, and the first type of cell also uses beams 1 to 4 to send paging DCI respectively.

[0414] In some embodiments, the paging DCI may be used to schedule paging messages.

[0415] That is, the paging DCI will indicate whether the paging message associated with the corresponding paging configuration will be sent. If the paging DCI indicates that the corresponding paging message should be sent, the network device will send the paging message according to the paging configuration.

[0416] S2104: Send a paging message in the target cell.

[0417] In some embodiments, the target cell comprises a cell of the first category.

[0418] In some embodiments, cells of the first category do not transmit SSBs and / or SIBs.

[0419] In some embodiments, the target cell may be a cell of the first category and / or a second cell.

[0420] In the embodiments of the present disclosure, the target cell may be a cell of the first category. The cell of the first category may be a cell that does not transmit SSBs and / or SIBs. On the one hand, the transmission of paging messages by the cell of the first category does not significantly increase power consumption. On the other hand, the cell of the first category can share the paging load of the second cell and improve the paging capacity of the system.

[0421] In some embodiments, if the target cell uses beam scanning to send paging DCI, the target cell also uses beam scanning to send paging messages. The beam configuration for sending the paging message may be the same as the beam configuration for sending SSB and / or SIB1 by the second cell.

[0422] FIG2B is an interactive diagram of a paging method according to an embodiment of the present disclosure. As shown in FIG2B , the embodiment of the present disclosure relates to a paging method for a communication system 100, the method comprising:

[0423] S2201: The network device sends the cell configuration of the first type of cell to the terminal in the second cell.

[0424] For example, the relevant content of the cell configuration can be found in the relevant part of the embodiment corresponding to FIG2A .

[0425] In some embodiments, the cell configuration can at least be used by the terminal to determine whether the first type of cell sends a paging message.

[0426] Exemplarily, the cell configuration may indicate whether the first type of cell is capable of sending a paging message, or whether the first type of cell shares the paging load of the second cell.

[0427] In some embodiments, if the cell configuration includes a paging configuration, the paging configuration may have the following characteristics:

[0428] Multiple first cells share a set of paging configurations, or,

[0429] The paging configurations of the multiple first cells are associated with each other, or,

[0430] The paging configurations of multiple first cells are independent of each other.

[0431] In some embodiments, when the multiple first cells include the second cell and a cell of the first type associated with the second cell, the paging configurations of the multiple first cells are associated with each other and include at least one of the following:

[0432] The paging frame of the third cell has an offset in the time domain relative to the paging frame of the second cell;

[0433] The paging frames of the adjacent third cells have a first interval in the time domain, and the paging frame of the first of the third cells has a second interval in the time domain relative to the paging frame of the second cell;

[0434] The paging frame of the adjacent third cell has a first step length in the time domain, and the paging frame of the first third cell has a second step length in the time domain relative to the paging frame of the second cell;

[0435] The third cell is a cell of the first type among the multiple first cells.

[0436] In some embodiments, the third cell is a cell of the first type among the first cells.

[0437] The adjacent third cell may be a cell whose cell index is adjacent to the first cell.

[0438] In some embodiments, the first interval may be equal to the second interval. In other embodiments, the first interval may not be equal to the second interval.

[0439] By setting the first interval and / or the second interval, the signaling overhead of the paging configuration can be reduced.

[0440] In some embodiments, the first step length may be equal to the second step length. In other embodiments, the second step length may not be equal to the first step length.

[0441] By setting the first step length and / or the second step length, the signaling overhead of the paging configuration can be reduced.

[0442] S2202: The network device sends first information to the terminal.

[0443] In some embodiments, the first information is used by the terminal to determine a target cell, a paging frame and / or a paging occasion for receiving a paging message.

[0444] In some embodiments, the first information indicates at least one of the following:

[0445] Target cell for paging DCI;

[0446] Paging frame for paging DCI;

[0447] Paging timing for paging DCI;

[0448] Paging group or paging subgroup; the paging group is associated with the cell, paging frame or paging opportunity in which the terminal receives downlink paging control information DCI; the paging subgroup is associated with the cell, paging frame or paging opportunity in which the terminal receives downlink control information DCI; the paging DCI is used to schedule paging messages.

[0449] In some embodiments, the first information may directly indicate a target cell for the terminal to receive the paging DCI.

[0450] In some embodiments, the first information indicates a paging frame for receiving a paging message, and the terminal can directly monitor the paging frame.

[0451] In some embodiments, the first information may be any network-side signaling or downlink signaling.

[0452] In some embodiments, the downlink signaling may include but is not limited to at least one of the following:

[0453] RRC signaling;

[0454] MAC Control Element (CE);

[0455] DCI.

[0456] In some embodiments, a target cell for receiving a paging message may be indicated to each terminal. In this case, the first information may include a cell index of the target cell, etc.

[0457] In other embodiments, the frame number of the paging frame in which the paging message is received may be indicated to each terminal. In this case, the first information may include the frame number of the optional paging frame in which the terminal receives the paging message. The frame number may be sent to the terminal as a frame number set. Because different paging frames are mapped to a first cell associated with a second cell, the terminal can determine the target cell for monitoring the paging message based on the optional paging frame in which it monitors the paging message.

[0458] In some embodiments, the paging occasions of multiple first cells associated with a second cell may share a set of paging occasion numbers. In this way, the paging occasion numbers (i.e., opportunity numbers) of the multiple first cells associated with a second cell within a DRX cycle are different. Accordingly, after receiving the first information, the terminal can determine the target cell based on the opportunity number of the paging frame.

[0459] In some embodiments, the network device may perform paging for a single terminal, or may perform paging based on a paging group or paging subgroup. If paging is performed based on a paging group or paging subgroup, the paging group or paging subgroup may be divided according to the terminal type, service, and / or UE_ID. If paging subgroups are divided, a paging group may include one or more paging subgroups.

[0460] Different paging groups or paging subgroups may be mapped to different first cells, paging frames and / or paging occasions, so that the network device may indirectly indicate to the terminal the target cell for receiving the paging message by sending the first information.

[0461] In some embodiments, the first information may be sent to the terminal along with the paging configuration.

[0462] In some embodiments, S2202 may include: sending a first signal carrying first information to the terminal.

[0463] In some embodiments, the first signal is used to wake up the second transceiver of the terminal.

[0464] In some embodiments, the power consumption of the second transceiver is higher than the power consumption of the first transceiver used by the terminal to receive the first signal.

[0465] In some embodiments, the first signal may be a low power wake-up signal (Low Power Wake Up Signal, LP-WUS).

[0466] For example, when a terminal includes a first transceiver and a second transceiver, the power consumption of the first transceiver may be lower than that of the second transceiver. That is, the power consumption of the first transceiver during operation may be lower than that of the second transceiver during operation. The first transceiver may be a standalone receiver and may only have a receiving function. The second transceiver may support both transmission and reception. For example, the first transceiver may be a low-power wake-up signal receiver (LP-WUR).

[0467] The first signal carries the first information, so that the terminal can obtain the first information when using the first transceiver to receive the first signal, without the need for the terminal to use the second transceiver to monitor the first information, which can save power consumption of the terminal.

[0468] In some embodiments, the network device may send the first information via a system information block, an RRC message, or a MAC CE.

[0469] S2203: Send paging DCI to the terminal on the target cell.

[0470] In some embodiments, the paging DCI is sent on the cell of the first type and / or the second cell.

[0471] In some embodiments, the paging DCI is used for scheduling paging messages.

[0472] For example, the paging DCI includes a paging configuration indicating the paging message to be received by the terminal. The paging configuration can refer to any of the above embodiments.

[0473] In some embodiments, the target cell for sending the paging DCI is the cell where the terminal monitors the paging message.

[0474] In some embodiments, the paging DCI is sent on the target cell using a beam scanning method.

[0475] In some embodiments, when the target cell is a cell of the first type and the paging DCI is sent using a beam scanning method, the paging DCI is sent on a cell using the beam configuration of the second cell for sending SSB and / or SIB.

[0476] In some embodiments, for example, the second cell uses beams in four directions, beams 1 to 4, to send SSB or SIB respectively, and the first type of cell also uses beams 1 to 4 to send paging DCI respectively.

[0477] In some embodiments, the paging DCI may be used to schedule a paging message. That is, the paging DCI may indicate whether a paging message associated with the corresponding paging configuration will be sent. If the paging DCI indicates that the corresponding paging message should be sent, the network device may send the paging message according to the paging configuration.

[0478] S2204: Send a paging message to the terminal in the target cell.

[0479] In some embodiments, the target cell comprises a cell of the first category.

[0480] In some embodiments, cells of the first category do not transmit SSBs and / or SIBs.

[0481] In this way, the first type of cells can also send paging messages. The sending of paging messages increases power consumption of the first type of cells only to a limited extent, and shares the paging load of the second cell, thereby improving the paging capacity of the wireless communication system.

[0482] Correspondingly, the terminal receives a paging message on the target cell.

[0483] In some embodiments, the terminal receives the paging message on the cell of the first category and / or the second cell.

[0484] In some embodiments, if the target cell uses beam scanning to send paging DCI, the target cell also uses beam scanning to send paging messages. The beam configuration for sending the paging message may be the same as the beam configuration for sending SSB and / or SIB1 by the second cell.

[0485] As shown in FIG4A , an embodiment of the present disclosure provides a method, which is performed by a network device of a second cell, including:

[0486] S4101: The network device of the second cell sends the cell configuration of the first type of cell.

[0487] In some embodiments, the second cell may be a regular cell.

[0488] In some embodiments, the first type of cell may be the aforementioned SSB / SIB1-deficient cell.

[0489] That is, the cells of the first category do not send SSB and / or SIB. Exemplarily, the cells of the first category do not send SSB and / or SIB1.

[0490] In some embodiments, when a cell of the first category is used as the first cell, the cell configuration may include a paging configuration.

[0491] In some embodiments, when the cell of the first category is not used as the first cell, the cell configuration may not include a paging configuration.

[0492] It is worth noting that, for an optional implementation manner in which the network device of the first type of cell sends the cell configuration, reference may be made to step S2101 of the corresponding embodiment in FIG. 2A .

[0493] S4102: Determine the target cell to which the paging message is sent.

[0494] Exemplarily, the network equipment of the second cell determines a target cell to send a paging message according to the UE_ID of the terminal to be paged. The target cell may include a cell of the first category and / or the second cell.

[0495] The optional step of determining the target cell to which the paging message is to be sent may refer to S2102 of the embodiment corresponding to FIG. 2A .

[0496] In some embodiments, a target cell is determined based on an identifier of the terminal and the number of first cells, and the target cell is used to send downlink control information (DCI) of the terminal; the first cell is used to send a paging message; the first cell includes a second cell of the second category and / or a cell of the first category associated with the second cell;

[0497] Determine the target cell according to the terminal identifier and the number of paging frames, where the number of paging frames is the total number of paging frames of all first cells in a discontinuous reception (DRX) cycle;

[0498] The target cell is determined according to the terminal identifier and the number of paging occasions; the number of paging occasions is the total number of paging occasions of all first cells in a discontinuous reception DRX cycle;

[0499] The paging DCI is used to schedule a paging message; the second cell and a cell of the first type associated with the second cell have overlapping coverage, and the second cell sends an SSB and / or a SIB.

[0500] Optionally, determining the target cell according to the identifier of the terminal and the number of first cells includes determining in at least one of the following ways:

[0501] Cell-index = UE_ID mod M;

[0502] Cell-index=Floor(UE_ID / N)mod M;

[0503] Cell-index=Floor(UE_ID / N / Ns)mod M;

[0504] Cell-index is the cell index of the target cell; UE_ID is the terminal identifier; M is the number of first cells; N is the number of paging frames of all first cells in a discontinuous reception DRX cycle; Ns is the number of paging occasions PO of all first cells in a DRX cycle.

[0505] In some embodiments, determining a target cell according to an identifier of a terminal and a number of paging frames includes:

[0506] Determine the target frame according to the terminal identifier and the number of paging frames;

[0507] The target cell is determined according to the first cell to which the target frame belongs; wherein the target frame is used for the target cell to send a paging DCI.

[0603] Some embodiments may include S5102, and the other steps are optional. For example, if the first-category cell can perform paging configuration itself, and the configuration of other cells can be pre-configured by the network management device, then step S5101 can be omitted. If it is determined that the target cell for sending the paging message is not itself, but a second cell or another first-category cell, then the subsequent steps can be omitted.

[0638] S5204: Send a paging message.

[0639] In some embodiments, the cell of the first category sends a paging DCI, and the cell of the first category sends a paging message.

[0640] It is worth noting that some embodiments may include S5201 alone, and the other steps are optional. For example, if the second cell, as an SSBI / SIB1-deficient cell, determines that it is not the first cell after receiving the cell configuration of the second cell, then subsequent steps S5202 to S5204 are all optional. Alternatively, if the second cell can send the first information but the second cell does not need to send the first information, then S5202 can be omitted.

[0641] Some embodiments may include S5201 and S5202; other steps are optional. For example, after a cell of the first category receives the cell configuration of a second cell, the second cell may send the first information and the second cell may send the first information. However, if the cell of the first category is not the first cell or is not the first cell to send the paging message, then subsequent steps S5203 to S5204 may be omitted.

[0642] Some embodiments may include S5202, and all other steps are optional. For example, if the first-category cell can perform paging configuration itself, and the configuration of other cells can be pre-configured by the network management device, then step S5201 can be omitted. If the second cell can send the first message and the second cell can send the first message, but the first-category cell is not the first cell or is not the first cell to send the paging message this time, then subsequent steps S5203 to S5204 can be omitted.

[0643] Some embodiments may include S5202 to S5204; the first type of cells may perform paging configuration by themselves, and other cell configurations may be pre-configured by the network management device.

[0655] In some embodiments, the target cell may include a cell of the first category and / or a second cell.

[0656] In some embodiments, the paging DCI is received on a target frame of the target cell.

[0657] In some embodiments, the paging DCI is received on a target occasion of the target cell.

[0658] S6104: Receive a paging message on the target cell.

[0659] In some embodiments, a paging message sent by a target cell is received at a corresponding time-frequency domain location according to the paging DCI.

[0660] It is worth noting that:

[0661] Some embodiments include S6101 alone. At this time, the terminal is in the RRC connected state, so it is obvious that the terminal has no need to be paged, and the subsequent S6102 to S6104 are all optional steps.

[0662] Some embodiments may include S6101 to S6103. For example, if the terminal determines that it has no paging message according to the received paging DCI, S6104 is an optional step. Alternatively, if the terminal does not receive the paging DCI on the target cell, the terminal does not need to continue to execute S6104.

[0663] As shown in FIG6B , an embodiment of the present disclosure provides a method, which is executed by a terminal and includes:

[0664] S6201: Receive the cell configuration of the first type of cell in the second cell.

[0665] In some embodiments, the terminal receives the cell configuration of the first type of cell by broadcast, multicast, or unicast by the second cell.

[0666] In some embodiments, the cell configuration can refer to the relevant parts of the embodiment corresponding to Figure 2A.

[0667] In some embodiments, the cell configuration may include a paging indication, and the paging indication may indicate whether the corresponding cell of the first category is the first cell.

[0668] In some embodiments, the first cell is the cell that will send the paging message.

[0670] In some embodiments, the first information may be used by the terminal to determine a target cell, a target frame, or a target timing for receiving a paging message.

[0671] It is worth noting that the optional method of S6202 can be found in the relevant part of the embodiment corresponding to FIG2B , which will not be repeated here.

[0672] S6203: Receive paging DCI on the target cell.

[0674] In some embodiments, the paging DCI is received on a target frame of the target cell.

[0675] In some embodiments, the paging DCI is received on a target occasion of the target cell.

[0676] In some embodiments, the paging DCI is sent according to the first information.

[0677] Exemplarily, the paging DCI is monitored on the first indicated target cell, target frame or target opportunity.

[0678] S6204: Receive a paging message on the target cell.

[0679] In some embodiments, a paging message sent by a target cell is received at a corresponding time-frequency domain location according to the paging DCI.

[0680] It is worth noting that:

[0681] Some embodiments include S6201 alone. At this time, the terminal is in the RRC connected state, and it is obvious that the terminal has no need to be paged. Therefore, the subsequent S6202 to S624 are all optional steps.

[0682] Some embodiments may include S6201 to S6203. For example, if the terminal determines that it has no paging message according to the received paging DCI, S6204 may be an optional step. Alternatively, if the terminal does not receive the paging DCI on the target cell, the terminal does not need to continue to execute S6104.

[0683] The embodiments of the present disclosure provide a method for sharing the paging load by using SSB-less cells in an SSB / SIB1-less cell deployment scenario. During the paging process, the terminal needs to determine the cell to receive the paging message to improve the paging capacity.

[0684] An SSB-less cell has an independent physical cell ID, logical cell ID or cell identity.

[0685] Cells in normal operation (or regular cells) broadcast the configuration information of SSB / SIB-less cells (i.e., the aforementioned cell configuration). SSB / SIB-less cells and cells in normal operation have overlapping coverage or adjacent coverage, meaning they are neighbors. The configuration information for SSB / SIB-less cells can be configured in the SIB1 of the normal operation cell or in a newly defined SIB.

[0686] The SSB-less cell and the person responsible for configuring the SSB-less cell have the same TAC.

[0687] If the configuration parameters of the SSB-less cell are default, that is, the SSB-less cell is not configured, then the default configuration parameters are the same as those of the anchor cell (anchor cell), which is a regular cell.

[0688] Exemplarily, the anchor cell is associated with the SSB-less cell responsible for configuring the SSB-less cell, that is, the normally operating cell.

[0689] The SSB-less cell and the anchor cell can be co-located or non-co-located. They can belong to the same wideband carrier or different wideband carriers. They can be intra-band or inter-band.

[0690] The anchor cell also configures whether each SSB-less cell can share paging transmissions, reducing the paging load on the anchor cell. This can be done, for example, if the SSB-less and anchor cells have the same coverage, such as being co-located and operating on the same wideband carrier.

[0691] The configuration information related to the SSB / SIB-less cell includes at least one of the following:

[0692] The index of the SSB / SIB-less cell, a positive integer starting from 1. There must be at least one SSB / SIB-less cell configured in the currently operating cell.

[0693] Can the SSB / SIB-less cell share the paging load from the anchor cell?

[0694] Identification information of the SSB / SIB-less cell, such as at least one of: physical cell identity (PCI), radio access network notification area code (RNAC), tracking area code (TAC), system information area code or system information area identifier, etc.

[0695] The beam transmission method of the SSB / SIB-less cell, such as the period, the maximum number of beams supported in one period, and the beam directions in which they are transmitted. This beam configuration can be used not only for SSB and / or SIB1, but also for other reference signals and / or service transmission.

[0696] Frequency information of SSB / SIB-less cells, such as frequency layer, SSB frequency, UL WUS frequency, etc.

[0697] List of slices supported by SSB / SIB-less cells.

[0698] Common configuration information for SSSB / SIB-less cells, such as RACH-related configuration information. The correspondence between RACH and / or random access preamble and SSB in a normal operating cell, or the correspondence between RACH and / or preamble and the SSB / SIB-less cell beams configured in a normal operating cell;

[0699] The conditions or threshold configuration information for initiating the RACH process to the SSB / SIB-less cell.

[0700] All or part of the configuration information of the SSB and / or SIB1 of the SSB / SIB-less cell.

[0701] DL timing deviation between the SSB / SIB-less cell and the currently operating cell.

[0702] The DL signal set indicates the coverage of an SSB / SIB-less cell. The DL signal set includes a CSI-RS set, an SSB set, or a set containing both CSI-RS and SSB. The DL signal set is used by the terminal to assess whether it is close to a sleeping cell or already within the coverage of an SSB / SIB-less cell.

[0703] Conditional configuration information can be used to assess whether a terminal is close to or within the coverage of an SSB / SIB-less cell. For example, based on the conditional configuration information, the terminal can measure the target signal to be greater than or less than a threshold configured on the network side. If the target signal is greater than the threshold, the terminal can be considered to be close to or within the coverage of an SSB / SIB-less cell.

[0704] Furthermore, based on the conditional configuration information, it is determined whether this measurement value is based on a single beam (per beam) or a beam group. The measurement value of the CSI-RS or SSB for a single beam is determined. The measurement quantity corresponding to this measurement configuration condition is RSRP, RSRQ, or SINR, which may depend on the network-side configuration.

[0705] The threshold can be for each CSI-RS or CSI-RS group, or for each SSB index, or for an SSB index group, or for both a CSI-RS and an SSB index group. The measurement value that the threshold can be used to evaluate can be for a single beam, such as a single CSI-RS or SSB, or can be a linear average value based on at least one beam, such as a linear average value of a group of CSI-RSs or a group of SSBs.

[0706] Method 2: The terminal displays the cell that has confirmed the receipt of the paging message.

[0707] Option 1: Paging cell index = UE_ID mod M.

[0708] Option 2: Paging cell index = floor (UE_ID / N) mod M.

[0709] Option 3: Paging cell index = floor (UE_ID / N / Ns) mod M.

[0710] The UE_ID is derived based on the 5G-S-TMSI. For example, 5G-S-TMSI mod 1024 or 5G-S-TMSI mod 4096. M is the number of first cells capable of transmitting paging messages. N is the number of PFs in a DRX cycle, and Ns is the number of POs in a PF.

[0711] Since not all SSB-less cells can be used to send paging messages, the network side will configure which cells can be used to send paging messages. Anchor cells can be used to send paging messages by default.

[0712] The first cell index (paging cell index) is the index of the cell that can send the paging message, that is, the cell indexes of the cells that can send the paging message are numbered in ascending order to obtain the first cell index.

[0713] Alternatively, the first cell index is an index configured by the network side for a cell capable of sending paging messages.

[0714] Method 3: The terminal implicitly and directly sends the paging message to the cell. For example, the PO or PF number is unified among the cells, and the cell to receive the paging message is indirectly determined by determining the PO or PF.

[0715] The most typical scenario is that all cells supporting paging messages share a set of paging message configuration parameters, such as the same DRX cycle, the same number of PFs in a DRX cycle, and the same number of POs in a PF. For details, please refer to Figure 3B and / or Figure 3C.

[0716] Option 1: All PFs within a DRX cycle of all cells supporting paging message transmission are numbered uniformly. For example, referring to FIG3B and / or FIG3C , the PF numbers are PF 0, PF 1, PF 2, ..., PF 8. The principle of uniform numbering of PFs within a DRX cycle of all carriers can be:

[0717] Option 1a: Number the first cells in the time domain in descending order according to the cell index or first cell index of the cell supporting paging. A cell supporting paging can be understood as a cell that can send a paging message.

[0718] Option 1b: On all cells that support paging, the PFs of all cells that support paging are numbered according to the principle of time domain first and then frequency domain or frequency domain first and then time domain. The order of the frequency domain can be based on the cell index of the cell that supports paging or the first cell index in order from small to large, or based on the frequency spectrum of the cell that supports paging from low to high. The spectrum can be the lower edge frequency point, center frequency point, or upper edge frequency point where the initial DL BWP of the carrier is located. Or it can be based on an order displayed and configured on the network side.

[0719] Based on the PFs with the same number, the terminal needs to determine the PF to receive the paging DCI. Based on the total number of PFs, the terminal_ID is determined based on the following formula:

[0720] PF index = UE_ID mod K, where K represents the number of all PFs in a DRX cycle.

[0721] PF index == floor(UE_ID / M) mod K, where M is the number of cells that can transmit paging messages. K represents the number of all PFs that are numbered in a DRX cycle.

[0722] PF index represents the number of the paging frame, which can also be called a frame number or a frame index.

[0723] The terminal determines the time domain position of the PF on a cell based on the following formula: (SFN+PF_offset) mod T=n, where n=0, 1, 2, ..., NN is the number of PFs on a first cell in a DRX cycle.

[0724] Option 2: All POs of all PFs in a DRX cycle of all cells that support paging messages are numbered uniformly. For example, the PO numbers in the above figure are PO 0, PO 1, PO 2, ..., P26. The principle of numbering all POs of all PFs in a DRX cycle of all cells can be:

[0725] Option 2a: number each cell in the time domain in descending order according to the cell index (cell index) or the first cell index (paging cell index) of the cell supporting the paging message.

[0726] Option 2b: On all cells that support the sending of paging messages, the POs of all cells that support paging messages are numbered according to the principle of first time domain and then frequency domain or first frequency domain and then time domain. The order of the frequency domain can be based on the cell index (cell index) or the first cell index (paging cell index) of the cell that supports paging messages from small to large, or based on the frequency spectrum of the cell that supports paging messages from low to high. The spectrum can be the lower edge frequency point, center frequency point, or upper edge frequency point where the initial downlink bandwidth part (Downlink BandWidthPart, DL BWP) of the cell is located. Or it can be based on an order displayed and configured on the network side.

[0727] Based on the POs with the same number, the terminal needs to monitor the POs. Based on the total number of POs, the terminal_ID is determined based on the following formula:

[0728] PO index = UE_ID mod X, where X represents the number of all POs after numbering within a DRX cycle. Or

[0729] PO index == floor(UE_ID / M) mod X, where M is the number of valid first cells that can transmit paging messages. X represents the number of all PFs after numbering in a DRX cycle.

[0730] or

[0731] PO index == floor(UE_ID / M / N) mod X, where M is the number of valid first cells capable of transmitting paging. X represents the number of all POs numbered in a DRX cycle. N represents the number of PFs in a DRX cycle.

[0732] PO index == floor(UE_ID / K) mod X, where M is the number of valid first cells capable of transmitting paging messages. X represents the number of all POs numbered in a DRX cycle. K represents the number of all PFs numbered in a DRX cycle.

[0733] PO index is the paging number, which can also be called the paging index.

[0734] The terminal determines the time domain position of the PF on a first cell based on the following formula:

[0735] (SFN+PF_offset) mod T = n, where n = 0, 1, 2, ..., N.

[0736] N is the number of PFs on a primary cell in a DRX cycle.

[0737] SFN is the system frame number.

[0738] PF_offset is the offset of the paging frame and can be configured by the network device.

[0739] T is the duration of the DRX cycle.

[0740] The terminal may also determine the PF of each first cell based on the different configuration methods given in method 5, for example, the PF of each first cell may also be determined according to an offset, a step, or a gap.

[0741] The terminal determines the time domain position of a PO on a first cell based on the determined PF and the number of actually transmitted SSBs, or based on the determined PF, the number of actually transmitted SSBs, and the starting PDDCH occasion index of each PO.

[0742] Mode 4: Based on LP-WUS, the terminal indicates the cell to monitor for paging messages. If the anchor cell supports LP-WUS and the terminal also supports LP-WUR, the network side uses LP-WUS to indicate paging and / or the cell index of the cell where the paging message is received. LP-WUS can carry at least one of the following:

[0743] Option 1: The paging indication information indicates paging indication information for a terminal group or terminal subgroup, and the paging indication information is also associated with information identifying the cell receiving the paging message, for example, the cell information can be a cell index. The LP-WUS can also further indicate the PF and / or PO receiving the paging message on the target cell.

[0744] Option 2: The paging indication information indicates paging indication information for a terminal group or terminal subgroup, and is also associated with at least one cell identifying the cell receiving the paging message, for example, a cell index. The terminal determines the target cell based on the terminal_ID, the total number of cells that support paging, and other information. The terminal can determine the target cell using methods similar to those described in Method 2 or Method 3.

[0745] The LP-WUS may further indicate the PF and / or PO receiving the paging in the target cell.

[0746] Mode 5: Principles for paging configuration in each primary cell:

[0747] For example, the paging configuration may be as follows:

[0748] Option 1: The anchor cell generates the paging configuration, and all cells supporting paging transmission share the same configuration parameters. Option 2: Each supporting primary cell uses its own paging configuration.

[0749] Option 3: Paging containment is configured on the anchor cell. There is an offset between the PF of each cell supporting paging transmission and the PF of the anchor cell. For example, the offset is based on the network side configuration.

[0750] Option 4: Paging configuration configured on the anchor cell: The PFs of the primary cells supporting paging are distributed with the anchor cell's PF as the starting point, using a specific step or gap. The step / gap length depends on the network configuration. The primary cells supporting paging are distributed with the anchor cell's PF as the starting point, using a step in increasing order of cell index. The step or gap is an integer number of system frame numbers (SFNs).

[0751] In some embodiments, the parameters involved in the paging configuration may include but are not limited to at least one of the following:

[0752] DRX cycle;

[0753] Bias;

[0754] Number of PFs in a DRX cycle;

[0755] The number of POs in a PF; the first PDCCH occasion indication of PO, etc.

[0756] Furthermore, the parameters involved in the paging configuration also include the above-mentioned PF interval offset and / or step size information.

[0757] The following is a cell configuration of a first-class cell:

[0758] Method 6: Beam scanning transmission of paging DCI.

[0759] The beam sweeping method for other cells is the same as that for the anchor cell (which may be the cell sending the SSB and / or SIB1). That is, the beam sweeping for the paging message sent by the SSB-less cell is based on the SSB of the anchor cell to perform beam sweeping and send the paging DCI.

[0760] The disclosed embodiments utilize SSB-less cells for offloading paging in SSB / SIB1-less cell deployment scenarios. During paging, a terminal must determine the target cell to receive the paging message. Sending paging messages via SSB-less cells improves the system's paging capacity. SSB / SIB1-less cells enable rapid deployment, rapid use, flexible deployment, and on-demand activation, enabling plug-and-play deployment, improving the flexibility and timeliness of network deployment.
