Description

Paging method, communication device and storage medium Technical Field

[0001] The present disclosure relates to the field of communication technology, and in particular to a paging method, a communication device, and a storage medium. Background Art

[0002] New Radio (NR) uses high-frequency spectrum over a wide range. Each cell can be configured with an initial Band Width Part (BWP). A Synchronization Signal and PBCH Block (SSB) can be configured on the initial BWP. This SSB is used by terminals to search and identify cells. Once a cell is found and identified by a terminal, it can access and reside on it, allowing the cell to provide communication services to the terminal.

[0003] In order to reduce the power consumption of the terminal when searching and identifying cells, the Absolute Radio Frequency Channel Number (ARFCN) and the Global Synchronization Channel Number (GSCN) are introduced to perform cell search and identification based on the synchronization grid.

[0004] Summary of the Invention

[0005] While improving the terminal's search and identification rate for cells, the cell's paging capacity needs to be increased.

[0006] Embodiments of the present disclosure provide a paging method, a communication device, and a storage medium.

[0007] According to a first aspect of an embodiment of the present disclosure, a paging method is provided, wherein the method includes: a network device sends a paging message to at least two terminals on multiple first carriers of a cell; the first carrier is a carrier that supports the sending of paging messages among multiple available carriers of the cell.

[0008] According to a second aspect of an embodiment of the present disclosure, a paging method is provided, wherein the method includes: a first terminal receives a paging message on a second carrier of a cell, wherein the cell has multiple first carriers for sending paging messages; the second carrier is one carrier of the first carrier.

[0009] According to a third aspect of an embodiment of the present disclosure, a network device is provided, including: a sending module, configured as a sending module, configured to send a paging message to at least two terminals on multiple first carriers of a cell; the first carrier is a carrier that supports the sending of paging messages among multiple available carriers of the cell.

[0010] According to a fourth aspect of an embodiment of the present disclosure, a terminal is provided, comprising: a receiving module configured to receive a paging message on a second carrier of a cell, wherein the cell has multiple first carriers for sending paging messages; and the second carrier is a carrier of the first carrier.

[0011] According to a fifth aspect of an embodiment of the present disclosure, a paging method is provided, which includes: a network device executing the paging method described in any technical manner of the first aspect; and a terminal executing the paging method described in any technical manner of the second aspect.

[0012] According to a sixth aspect of an embodiment of the present disclosure, a storage medium is provided, wherein the storage medium stores instructions, which, when executed on a communication device, enable the communication device to execute the paging method provided by the first aspect and / or the second aspect.

[0013] According to the technical approach provided by the embodiments of the present disclosure, network equipment will send paging messages on multiple carriers, which is equivalent to a cell sending paging messages on only one carrier. This can increase the paging capacity of a single cell and the paging capacity of the entire communication system, and can reduce paging congestion compared to sending paging messages on a single carrier.

[0045] Among them, Carrier-index is the carrier index of the second carrier, UE_ID is the identifier of the first terminal; M is the number of first carriers in the cell; N is the number of paging frames of all first carriers in a discontinuous reception DRX cycle; Ns is the number of paging occasions PO of all first carriers in a DRX cycle.

[0046] In the above embodiment, the carrier index is determined in the manner described above.

[0056] In combination with some embodiments of the first aspect, in some embodiments, paging frames in the same DRX cycle on all first carriers are sequentially numbered.

[0057] In the above embodiment, the paging frames in the same DRX cycle of all first carriers are sequentially numbered, so both the terminal and the network device can easily know the second carrier according to the paging frame numbers.

[0060] Sequentially number the paging frames of the first carrier in the same DRX cycle from front to back or from back to front according to the time domain positions of the paging frames;

[0061] The paging frames of the first carrier 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.

[0062] In combination with some embodiments of the first aspect, in some embodiments, determining the second carrier from multiple first carriers according to the identifier of the first terminal of the at least two terminals and the number of paging opportunities in a discontinuous reception DRX cycle on all first carriers in the cell includes:

[0063] Determining a target timing according to the identifier of the first terminal and the number of paging occasions of all first carriers in the cell within a non-DRX period;

[0064] The second carrier is determined according to the first carrier to which the target opportunity belongs.

[0065] Based on the above solution, the second carrier is determined simultaneously in the process of determining the target timing, which has the characteristic of simple implementation.

[0068] PO-index = UE_ID mod X;

[0069] PO-index=Floor(UE_ID / M)mod X;

[0070] PO-index=Floor(UE_ID / M / N)mod X;

[0073] 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.

[0074] In combination with some embodiments of the first aspect, in some embodiments, paging occasions in the same DRX cycle on all first carriers are sequentially numbered.

[0075] Based on the above approach, the paging occasions of the multiple first carriers in the same DRX cycle are sequentially numbered, so that the subsequent terminal can simply determine the second carrier for monitoring the paging message according to the paging occasion.

[0076] In combination with some embodiments of the first aspect, in some embodiments, paging occasions in the same DRX cycle on all first carriers are sequentially numbered.

[0079] Sequentially number the paging occasions of all first carriers in the same DRX cycle from front to back or from back to front according to the time domain position of the paging frame;

[0080] The paging occasions of all first carriers 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.

[0081] Based on the above method, several implementation methods for numbering paging occasions for multiple first carriers on the same DRX cycle are provided, which are simple to implement.

[0083] The first index is the index of the available carrier of the cell;

[0084] The second index is the index of the first carrier of the cell.

[0085] Based on the above approach, the carrier index may be a carrier index obtained by numbering all carriers in a cell or an index of the first carrier, so that the carrier index used to determine the second carrier may be flexibly selected as needed.

[0086] In conjunction with some embodiments of the first aspect, in some embodiments, the method further includes:

[0090] Paging timing for paging DCI;

[0091] Paging group or paging subgroup; the paging group is associated with the carrier, paging frame or paging opportunity on which the terminal receives paging DCI; the paging subgroup is associated with the carrier, paging frame or paging opportunity on which the terminal receives paging DCI.

[0092] 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.

[0093] In conjunction with some embodiments of the first aspect, in some embodiments, the network device sending first information to at least two terminals includes:

[0094] A first signal carrying first information is sent to at least two terminals, 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 the power consumption of the first transceiver of the terminal receiving the first signal.

[0095] 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.

[0096] In conjunction with some embodiments of the first aspect, in some embodiments, the method further includes:

[0097] The network device sends second information to at least two terminals, where the second information includes a paging configuration of the first carrier.

[0100] The paging configurations of the multiple first carriers are associated with each other, or,

[0101] The paging configurations of the multiple first carriers are independent of each other.

[0102] Based on the above manner, there are multiple forms of the paging configuration, and the required paging configuration can be flexibly selected as needed later.

[0103] In conjunction with some embodiments of the first aspect, in some embodiments,

[0104] The first carrier includes a third carrier and a fourth carrier, and the paging configurations of the plurality of first carriers are associated with each other, including:

[0108] The third carrier is an anchor carrier in the first carrier; the fourth carrier is a first carrier other than the third carrier.

[0109] Based on the above manner, several implementation methods for associating the paging configurations of multiple first carriers are provided, which have the characteristic of being simple to implement.

[0110] In conjunction with some embodiments of the first aspect, in some embodiments, sending a paging message to at least two terminals on multiple first carriers of a cell includes:

[0111] Paging downlink control information DCI is sent to the terminal in a beam scanning manner on multiple first carriers of a cell; the paging DCI is used to schedule paging messages.

[0112] Based on the above method, when the first cell uses beam scanning to send paging DCI, this can be applicable to the scenario where the first cell uses beam communication.

[0113] In combination with some embodiments of the first aspect, in some embodiments, the beam scanning method for sending paging messages on multiple first carriers is the same as the beam scanning method for sending synchronization signal broadcast blocks SSB and / or system information blocks SIB1 by the cell.

[0114] Based on the above method, since some carriers of the cell do not send SSB and / or SIB, when the cell sends paging DCI, the paging DCI can be sent according to the beam configuration using SSB and / or SIB, 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 through a set of beam configurations. On the other hand, the terminal can know the method of monitoring paging DCI while knowing the reception of SSB and / or SIB through the reception of a beam configuration, which has the characteristic of low signaling overhead.

For another example, if the description object is a "level", the ordinal number before the "level" in the "first level" and the "second level" does not limit the priority between the "levels". For another example, the number of description objects is not limited by the ordinal number and can be one or more. Taking "first device" as an example, the number of "devices" can be one or more. In addition, the objects modified by different prefixes can be the same or different. For example, if the description object is "device", then the "first device" and the "second device" can be the same device or different devices, and their types can be the same or different; for another example, if the description object is "information", then the "first information" and the "second information" can be the same information or different information, and their contents can be the same or different.

[0192] FIG1A is a schematic diagram showing the architecture of a communication system according to an embodiment of the present disclosure.

[0193] 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.

[0194] 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.

[0195] In some embodiments, the terminal is also referred to as User Equipment (UE).

[0196] 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.

[0197] 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.

[0198] 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.

[0199] 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).

[0200] 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.

[0201] 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. The entities may be connected or disconnected, and the connection may be in any manner, including direct or indirect, wired or wireless.

[0202] The embodiments of the present disclosure can 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 802.20, 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.

[0203] In some embodiments, the terminal may operate on an initial BWP or on a spectrum range larger than the initial BWP. For example, the terminal may operate on a dedicated BWP. In some cases, the terminal may be equipped with multiple dedicated BWPs, for example, four dedicated BWPs, and these multiple dedicated BWPs belong to the same frequency band. In order to make up for the problem of limited uplink (UL) coverage caused by high-frequency bands, a supplementary uplink (SUL) carrier is introduced. At this time, a cell may include one downlink (DL) carrier and two UL carriers. The normal uplink carrier (NUL) and SUL are closely coordinated and belong to the same cell. Of course, SUL is an optional carrier, and a cell may only have a DL carrier and a UL carrier.

[0204] Furthermore, considering that the terminal may operate at high frequency or higher frequency, that is, the spectrum range of communication between the terminal and the network device is larger, the cell search and identification time is longer, resulting in increased power consumption of the terminal and increased search difficulty. Therefore, it is necessary to reduce the terminal's search for cells and / or identification of cells, which is a problem that needs to be further solved.

[0205] As shown in Figure 1B, a cell can support multiple DL carriers. Figure 1B shows a cell configured with 4 DL carriers, which constitute a wideband carrier. SSB and / or SIB1 are sent on one of the DL carriers (for example, DL carrier 3). Paging messages are sent and random access channels (RACH) are configured on other DL carriers, such as DL carrier 1, DL carrier 2, and DL carrier 4. When performing a cell search, the terminal can monitor SSB and / or SIB1 on a DL carrier 3, which can reduce the number of cells that the terminal needs to search, thereby reducing the time it takes for the terminal to search and identify the cell, reducing the power consumption required for the terminal to search and / or identify the cell, and reducing the time it takes for the terminal to search and / or identify the cell. After searching for the cell, the terminal can discover that the cell has other DL carriers based on system information on a DL carrier. These DL carriers can be used for the terminal to receive downlink data.

[0206] In view of this, as shown in FIG2A , an embodiment of the present disclosure provides a paging method that can be executed by the communication system shown in FIG1A . The method includes:

[0207] S2101: The network device sends second information to at least two terminals.

[0208] In some embodiments, the network device may be an access network device.

[0209] In some embodiments, the second information includes a paging configuration for the first carrier. The paging configuration may be a configuration for sending paging downlink control information (DCI) on multiple first carriers. The paging DCI is used to schedule the sending of paging messages. The paging message may be used to page a terminal in an idle or inactive state, causing the terminal to enter a connected state.

[0210] In some embodiments, the paging configuration may include configuration of at least one paging frame and / or configuration of at least one paging occasion, and the configuration here may include configuration of time-frequency domain resources.

[0211] In some embodiments, the paging configuration may include: carrier information of the first carrier. The carrier information may include information such as a carrier index, a carrier direction, and / or a carrier frequency, which may be used to determine a carrier for monitoring paging messages in the cell.

[0212] In some embodiments, the first cell may be a wideband carrier cell or a multi-carrier cell. The carrier of the wideband carrier cell is a first-type carrier. A first-type carrier includes multiple second-type carriers. The bandwidth of the second-type carrier is smaller than that of the first-type carrier. That is, the cell may have multiple carriers. The carrier here is the cell's downlink (DL) carrier. The downlink carrier here is a second-type carrier. A first-type carrier may include multiple downlink carriers. The downlink carrier is used for downlink transmission.

[0213] In some embodiments, multiple carriers of the cell may all be available carriers of the cell.

[0214] In some embodiments, the first carrier of the cell may be part or all of the available carriers of the cell.

[0215] In some embodiments, the first carrier may be the carrier that sends the paging message.

[0216] In some embodiments, the network device transmits the SSB and / or SIB on an available carrier of the cell. Exemplarily, the carrier transmitting the SSB and / or SIB may be the anchor carrier of the cell. Of course, in addition to the anchor carrier, the cell also includes other DL carriers.

[0217] In some embodiments, the network device may broadcast, multicast, or unicast the second information on one carrier.

[0218] For example, the network device may broadcast, multicast, or unicast the second information on the anchor carrier. Alternatively, the network device may broadcast, multicast, or unicast the second information on other carriers except the anchor carrier.

[0219] In some embodiments, the network device transmits the second information on the anchor carrier.

[0220] In some embodiments, the network device transmits the second information on the first carrier.

[0221] In some embodiments, the network device sends the second information on all available carriers of the cell.

[0222] In some embodiments, the network device sends a paging message to any one or more terminals in the cell on one or more first carriers of the cell. If the network device sends the paging message on multiple first carriers, the paging capacity of the cell can be increased and the paging load of sending the paging message on a single carrier can be reduced.

[0223] In some embodiments, when a network device pages a terminal at a time, the network device may page the terminal on one of the multiple first carriers, thereby increasing the paging capacity of the cell.

[0224] In some embodiments, the carrier that sends the paging message may be referred to as a first carrier.

[0225] In some embodiments, the paging configurations of the multiple first carriers are independent of each other, so as to maximize the flexibility of sending paging messages on different first carriers.

[0226] In some embodiments, multiple first carriers share a common paging configuration.

[0227] In this case, the network device will send a set of paging configurations, which can be used by the terminal to monitor paging messages on any carrier in the cell.

[0228] In some embodiments, the paging configurations of the plurality of first carriers are associated with each other.

[0229] In this case, the paging configurations of multiple carriers are associated with each other, so that the signaling overhead when the paging configurations are sent to the terminal can be reduced based on the association.

[0230] The first carrier includes a third carrier and a fourth carrier,

[0231] The first carrier includes a third carrier and a fourth carrier, and the paging configurations of the plurality of first carriers are associated with each other, including:

[0232] The paging frame of the fourth carrier has an offset in the time domain relative to the paging frame of the third carrier;

[0233] The adjacent paging frames of the fourth carrier have a first interval in the time domain, and the first paging frame of the fourth carrier has a second interval in the time domain relative to the paging frame of the fourth carrier;

[0234] The paging frame of the adjacent fourth carrier has a first step length in the time domain, and the paging frame of the first fourth carrier has a second step length in the time domain relative to the third carrier;

[0235] The third carrier is an anchor carrier in the first carrier; the fourth carrier is a first carrier other than the third carrier.

[0236] In some embodiments, the third carrier may be an anchor carrier for transmitting SSBs and / or SIBs.

[0237] As shown in Figure 3A, it is a schematic diagram of the frame numbering of the paging frames of multiple first carriers. The third carrier may be carrier x. The carrier index of carrier x is smaller than the carrier index of carrier y, and the carrier index of carrier y is smaller than the carrier index of carrier z. When the paging frames are numbered from small to large according to the carrier index, and the paging frames of a single carrier are numbered from front to back in the time domain, the frame numbering of the paging frames shown in Figure 3A will be obtained. The paging frames of carrier x include: paging frames (PF) 1, PF2, and PF3, where 1, 2, and 3 are all frame numbers. The paging frames of carrier y are numbered from 4 to 6, and the frames of carrier z are numbered from 7 to 9.

[0238] As shown in Figure 3B, it is a schematic diagram of the frame numbering of the paging frames of multiple first carriers. The carrier index of carrier x is smaller than the carrier index of carrier y, and the carrier index of carrier y is smaller than the carrier index of carrier z. When the paging frames are numbered from small to large according to the carrier index, and the paging frames of all first carriers 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 carrier x include: paging frames (PF) 1, PF4, and PF7, where 1, 4, and 7 are all frame numbers. The paging frames of carrier y are numbered 2, 5, and 8; the paging frames of carrier z are numbered 3, 6, and 9.

[0239] 3A and 3B , a paging frame includes multiple paging occasions (POs). For example, a paging frame may include three POs, namely PO1, PO2, and PO3.

[0240] FIG3C is a schematic diagram showing frame numbering of paging frames for multiple first carriers. Carrier y and carrier z are both first carriers. The anchor carrier is the fourth carrier. Carrier y and carrier z are both third carriers.

[0241] As shown in Figure 3C , the anchor carrier has multiple PFs within a DRX cycle. PF1 of carrier y is offset from PF1 of the anchor carrier. Alternatively, PFs can be sorted from largest to smallest or from smallest to smallest based on index number, with PFs with the same ranking within a DRX cycle having a specified step size or interval.

[0242] 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.

[0243] In some embodiments, the network device sends the second information to the second transceiver or the first transceiver of the terminal.

[0244] The second transceiver may be a main radio (MR) of the terminal. The first transceiver may be a separate receiver. The first transceiver may be a low power wake up signal receiver (LP-WUS).

[0245] S2102: Determine a second carrier.

[0246] In some embodiments, the network device and / or the terminal respectively determine the second carrier.

[0247] In some embodiments, the network device and / or the terminal may determine the second carrier in the following manner:

[0248] Determine, according to an identifier of a first terminal among the at least two terminals and the number of first carriers of the cell, a second carrier from a plurality of first carriers, where the second carrier is used to send downlink control information (DCI) of paging of the terminal;

[0249] Determining a second carrier from multiple first carriers according to an identifier of a first terminal among the at least two terminals and a number of paging frames in a discontinuous reception (DRX) cycle on all first carriers of the cell; the target paging frame is used to send a paging DCI of the terminal on the second carrier;

[0250] Determine, based on an identifier of a first terminal among the at least two terminals and a number of paging occasions in a discontinuous reception (DRX) cycle on all first carriers in the cell, a second carrier from the plurality of first carriers, where the target occasion is used to send a paging DCI of the terminal on the second carrier;

[0251] The paging DCI is used to schedule paging messages.

[0252] In some embodiments, determining the second carrier from multiple first carriers based on an identifier of a first terminal among the at least two terminals and the number of first carriers of a cell includes at least one of the following:

[0253] Carrier-index=UE_ID mod M;

[0254] Carrier-index=Floor(UE_ID / N)mod M;

[0255] Carrier-index=Floor(UE_ID / N / Ns)mod M;

[0256] Among them, Carrier-index is the carrier index of the second carrier, UE_ID is the identifier of the first terminal; M is the number of first carriers in the cell; N is the number of paging frames of all first carriers in a discontinuous reception DRX cycle; Ns is the number of paging occasions PO of all first carriers in a DRX cycle.

[0257] In some embodiments, the UE_ID may include but is not limited to a temporary mobile subscriber identity (TMSI) of the first terminal.

[0258] In some embodiments, the TMSI may further be a 5G globally unique temporary UE identifier (5th Generation S-Temporary Mobile Subscriber Identity, 5G-S-TMSI).

[0259] 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.

[0260] In some embodiments, Floor represents rounding down.

[0261] The first terminal and the network device may determine a formula for calculating the carrier index according to a protocol agreement or pre-configuration.

[0262] Of course, the above is merely a calculation method for determining the carrier index of the second carrier, and the specific implementation is not limited to the above example.

[0263] In this case, after the second carrier is determined, the paging frame and / or paging opportunity for sending a paging message to the corresponding terminal can be determined according to relevant technologies and in combination with the UE_ID.

[0264] In some embodiments, the time domain position of a paging frame (PF) may be determined according to the following functional relationship:

[0265] (SFN+PF_offset) mod T = n;

[0266] SFN is the super frame number.

[0267] PF_offset is the offset of PF;

[0268] T is the duration of the DRX cycle;

[0269] n is the number of the paging frame in a DRX cycle.

[0270] 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:

[0271] i_s=floor(UE_ID / N)mod Ns;

[0272] i_s is the index of PO.

[0273] N is the number of paging frames in a DRX cycle.

[0274] Ns is the number of paging occasions in one DRX cycle.

[0275] In some embodiments, determining the second carrier from multiple first carriers according to an identifier of a first terminal among the at least two terminals and a number of paging frames in a discontinuous reception DRX cycle on all first carriers of the cell includes:

[0276] Determine a target frame according to the identifier of the first terminal and the number of paging frames of all first carriers in the cell within a DRX cycle;

[0277] A second carrier is determined according to the first carrier to which the target frame belongs.

[0278] After the paging frames on the multiple first carriers are numbered, the paging frame (ie, the target frame) for the first terminal to monitor the paging DCI may be determined first, and then the first carrier to which the target frame belongs may be determined as the second carrier.

[0279] In some embodiments, the target frame is determined according to the identifier of the first terminal and the number of paging frames of all first carriers in the cell in a DRX cycle, and may include but is not limited to at least one of the following: PF-index = UE_ID mod K;

[0280] PF-index=Floor(UE_ID / M)mod K;

[0281] Among them, PF-index is the frame number of the target frame; UE_ID is the identifier of the first terminal; M is the number of first carriers in the cell; the first carrier supports the carrier for sending paging messages; K is the number of paging frames in a DRX cycle.

[0282] In this case, the paging frames of all primary carriers within a DRX cycle are sequentially numbered, i.e., all primary carriers within a cell share the same set of numbers. Thus, multiple paging frames within a DRX cycle have different frame numbers, and each paging frame is mapped to one primary carrier. Therefore, once the paging frame is determined, the secondary carrier for sending the terminal's paging message is also determined.

[0283] In some embodiments, the paging frames on the multiple first carriers in the same DRX cycle are sequentially numbered.

[0284] In some embodiments, the paging frame sequence numbers on the multiple first carriers in the same DRX cycle include at least one of the following:

[0285] Sequentially number the paging frames of the multiple first carriers in the same DRX cycle according to the carrier indexes of the multiple first carriers from large to small or from small to large;

[0286] Sequentially numbering the paging frames of the plurality of first carriers in the same DRX cycle from front to back or from back to front according to the time domain positions of the paging frames;

[0287] The paging frames of the plurality of first carriers 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.

[0288] In some other embodiments, the carrier index of the first carrier may include: a carrier index of the first carrier associated with a fourth carrier. That is, in some embodiments, the carrier index is the first index or the second index;

[0289] The first index is the index of the available carrier of the cell;

[0290] The second index is the index of the first carrier of the cell.

[0291] In some embodiments, the carrier index of the second carrier includes the aforementioned first index and / or second index.

[0292] In some embodiments, the number of first carriers in a cell may be less than or equal to the number of available carriers in the cell. The available carriers may be second-type carriers configured in the cell.

[0293] In some embodiments, the paging frames are numbered from small to large according to the carrier index, which can be understood as: first completing the numbering of the paging frames of the carrier with a small index, and then numbering the paging frames of the carrier with a large index.

[0294] In some embodiments, the paging frames are numbered from small to large according to the carrier index, which can be understood as: first completing the numbering of the paging frames of the carrier with a large index, and then numbering the paging frames of the carrier with a small index.

[0295] 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.

[0296] 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.

[0297] First, the paging frames with larger or smaller carrier indexes are prioritized according to the carrier 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.

[0298] First, the paging frames with larger or smaller carrier indexes are prioritized according to the carrier index sorting, and the paging frames are numbered according to the frequency domain positions from high to low or from low to high.

[0299] In summary, there are multiple ways to number paging frames, and the paging frames may be numbered in sequence based on carrier index, time domain position, and / or frequency domain position.

[0300] In some embodiments, determining the second carrier from multiple first carriers according to an identifier of a first terminal among the at least two terminals and a number of paging occasions in a discontinuous reception DRX cycle on all first carriers in a cell includes:

[0301] Determining a target timing according to the identifier of the first terminal and the number of paging occasions of all first carriers in the cell within a non-DRX period;

[0302] The second carrier is determined according to the first carrier to which the target opportunity belongs.

[0303] In the embodiment of the present disclosure, the target timing and the second carrier are determined simultaneously in one determination process, which has the characteristic of simple implementation.

[0304] In some embodiments,

[0305] Determining the target timing according to the identifier of the first terminal and the number of paging occasions of all first carriers in the cell in a non-DRX period includes at least one of the following:

[0306] PO-index = UE_ID mod X;

[0307] PO-index=Floor(UE_ID / M)mod X;

[0308] PO-index=Floor(UE_ID / M / N)mod X;

[0309] PO-index=Floor(UE_ID / K)mod X;

[0310] Among them, PO-index is the timing number of the target timing; UE_ID is the identifier of the first terminal; M is the number of first carriers in the cell; X is the number of paging opportunities in a DRX cycle; K is the number of paging frames in a DRX cycle.

[0311] In some embodiments, the paging occasions within the same DRX cycle on all first carriers are sequentially numbered.

[0312] In some embodiments, the paging frame sequence numbers within the same DRX cycle on all first carriers include at least one of the following:

[0313] Sequentially number the paging frames of the first carrier in the same DRX cycle according to the carrier index of the first carrier from large to small or from small to large;

[0314] Sequentially number the paging frames of the first carrier in the same DRX cycle from front to back or from back to front according to the time domain positions of the paging frames;

[0315] The paging frames of the first carrier 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.

[0316] In some other embodiments, the paging occasions may be numbered in descending order or in ascending order according to the carrier index.

[0317] For example, if a cell has M carriers, the carrier indexes for that cell range from 0 to M-1. The carrier with a carrier index of 0 may be the anchor carrier, also referred to as the third carrier. Carrier indexes greater than 0 may represent carriers other than the anchor carrier. 0 to M-1 are examples of first indices.

[0318] As another example, X carriers of the M carriers in the cell are used as first carriers, and the indexes of the first carriers are 0 to X-1. 0 to X-1 are first carrier indexes, which are also examples of second indexes.

[0319] Of course, the first index and the second index can be numbered starting from 0 or 1, and are not limited to the above examples.

[0320] In some embodiments, POs of the same order within time-domain aligned PFs on various first carriers 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 carriers may have a specified offset, interval, or step size in the time domain based on a fourth carrier.

[0321] S2103: The network device sends a paging DCI.

[0322] In some embodiments, the paging DCI is sent to the first terminal on the second carrier.

[0323] In some embodiments, the second carrier is one of the aforementioned first carriers.

[0324] In some embodiments, the paging DCI is sent on a target frame.

[0325] In some embodiments, the paging DCI is sent on a target occasion.

[0326] In some embodiments, paging DCI is sent to multiple terminals on one or more first carriers of a cell.

[0327] In some embodiments, paging DCI is used to schedule paging messages.

[0330] In some embodiments, the network device transmits paging DCI on multiple first carriers using a beam configuration for transmitting SSBs and / or SIBs on an anchor carrier.

[0331] In some embodiments, the network device sends the paging DCI on one or more first carriers using the same or different beam scanning methods.

[0332] In some embodiments, the network device may also use different beam configurations on different carriers to send paging DCI in a beam scanning manner.

[0334] In some embodiments, the network device sends a paging message to at least two terminals on one or more first carriers.

[0335] In some embodiments, the network device sends a paging message to the first terminal on a second carrier.

[0336] In some embodiments, the network device sends a paging message on one of a plurality of carriers supporting paging transmission in a cell according to the paging DCI.

[0337] Since the network device sends the paging message on multiple carriers in a cell, the paging capacity of the cell and / or the wireless communication system can be increased compared to sending the paging message on one carrier.

[0338] As shown in FIG2B , an embodiment of the present disclosure provides a paging method that can be performed by the communication system shown in FIG1A . The method includes:

[0339] S2201: The network device sends second information.

[0340] In some embodiments, the network device is an access network device of a wide carrier cell or a multi-carrier cell.

[0341] In some embodiments, the network device sends the second information to at least two terminals.

[0342] In the embodiment of the present disclosure, the optional manner in which the network device sends the second information can be found in the relevant description of the embodiment corresponding to FIG. 2A .

[0343] In some embodiments, the second information includes a paging configuration.

[0344] In some embodiments, optional methods of paging configuration can be found in the relevant description of the corresponding example in Figure 2A, which will not be repeated here.

[0345] S2203: The network device sends the first information.

[0346] In some embodiments, the first information is used by the terminal to determine a carrier, a paging frame and / or a paging occasion for receiving a paging message.

[0347] In some embodiments, the network device broadcasts, multicasts, or unicasts the first information.

[0348] In some embodiments, the network device broadcasts, multicasts, or unicasts the first information on the anchor carrier.

[0349] In some embodiments, the network device sends the first information to a first terminal. The first terminal may be a terminal to be paged.

[0350] In some embodiments, the first information may be used at least for the terminal to determine a second carrier for receiving the paging DCI.

[0351] In some embodiments, the network device first determines the second carrier for sending the paging DCI before sending the first information. For the method of determining the second carrier, please refer to the relevant part of the embodiment corresponding to FIG. 2A .

[0352] In some other embodiments, the network device may determine the second carrier from the plurality of first carriers according to the load of each first carrier and / or the carrier currently used by the paging terminal.

[0353] In some embodiments, the network device broadcasts, multicasts, or unicasts the first information on the first carrier.

[0354] In some embodiments, the network device sends first information, where the first information indicates at least one of the following:

[0355] The second carrier of the paging DCI;

[0356] Paging frame for paging DCI;

[0357] Paging timing for paging DCI;

[0358] Paging group or paging subgroup; the paging group is associated with the carrier, paging frame or paging opportunity on which the terminal receives paging DCI; the paging subgroup is associated with the carrier, paging frame or paging opportunity on which the terminal receives paging DCI.

[0359] In some embodiments, the network device sends a first signal carrying first information to the terminal.

[0360] In some embodiments, the terminal receives the first signal using a first transceiver.

[0361] In some embodiments, the first signal is used to wake up the second transceiver of the terminal.

[0362] In some embodiments, the power consumption of the second transceiver is higher than the power consumption of the first transceiver.

[0363] In some embodiments, the first signal may be a low power wake-up signal (Low Power Wake Up Signal, LP-WUS).

[0364] 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).

[0365] 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.

[0366] In some embodiments, the network device may send the first information via a system information block, a radio resource control (RRC) message, or a media access control (MAC).

[0367] In this case, the terminal not only receives the first information sent by the network device, but also receives the second information. After receiving the first information, the terminal can know the paging configuration.

[0368] After receiving the paging configuration, the second carrier, paging frame and / or paging occasion for monitoring the paging DCI may be determined according to the second information.

[0369] In some embodiments, before the network device sends the first information, it can use the optional method corresponding to the embodiment of Figure 2A to determine the second carrier, target frame and / or target timing, and then receive the second carrier, target frame and / or target timing of the paging message through the first information at least terminal.

[0370] In some embodiments, the network device may determine the second carrier, target frame and / or target timing by using relevant technologies, and then indicate the second carrier, target frame and / or target timing to the terminal through the first information.

[0371] In some other embodiments, the network device may dynamically determine the carrier, paging frame and / or paging opportunity for sending the paging message according to the loads of multiple carriers in the cell, and send the first information according to the determination result.

[0373] In some embodiments, the network device sends the paging DCI on a second carrier selected from the plurality of first carriers according to the first information.

[0379] In some embodiments, the network device may send paging messages in an optional manner, as described in the corresponding embodiment of FIG2A . Because the network device sends paging messages on multiple carriers within a cell, this can increase the paging capacity of the cell and / or wireless communication system compared to sending paging messages on a single carrier.

[0410] Determining a target timing according to the identifier of the first terminal and the number of paging occasions of all first carriers in the cell within a non-DRX period;

[0411] The second carrier is determined according to the first carrier to which the target opportunity belongs.

[0433] In some embodiments, paging messages are monitored according to the paging DCI.

[0434] In some embodiments, the paging DCI may indicate a time-frequency domain location where the terminal monitors the paging message. For example, the paging DCI indicates on which first carrier the terminal monitors the paging message.

[0435] It is worth noting that some embodiments may include S3101, and the other steps may be optional. For example, if a terminal in a connected state receives the second information but has not entered an idle state or an inactive state, it is not necessary to determine a second carrier for receiving a paging message, monitor the paging DCI, and monitor the paging message. In other words, the other steps are optional.

[0436] Some embodiments may include S3101 to S3103, and step S3104 is an optional step. For example, the terminal determines through monitoring of the paging DCI that it does not need to receive the paging message in the next paging occasion or the next paging frame, so S3104 is an optional step.

[0457] In some embodiments, the first signal may be a low power wake-up signal (Low Power Wake Up Signal, LP-WUS).

[0458] 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).

[0459] 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.

[0530] In some embodiments, the network device may transmit DCI in a beam scanning manner using a beam configuration different from that used to transmit SSBs and / or SIBs on an anchor carrier.

[0531] In some embodiments, the network device sends the paging DCI on multiple first carriers.

[0532] In some embodiments, the first carrier may include an anchor carrier and at least one non-anchor carrier. The non-anchor carrier is an available carrier other than the anchor carrier.

[0533] In some embodiments, the first carrier may include multiple non-anchor carriers.

[0534] In some embodiments, the network device may send paging DCI on the anchor carrier and / or at least one non-anchor carrier.

[0535] It is worth noting that the optional manner of sending the paging DCI by the network device may refer to any optional manner of sending the paging DCI in the embodiment of FIG. 2A .

[0536] S4204: Send a paging message.

[0537] In some embodiments, the paging message is sent according to the paging DCI.

[0538] In some embodiments, the network device sends the paging message using a beam scanning method.

[0539] In some embodiments, the network device sends the paging message on one or more carriers.

[0540] In some embodiments, the network device sends the paging message on the anchor carrier and at least one non-anchor carrier.

[0541] In some embodiments, the network device may send a paging message in a beam scanning manner according to the beam configuration of the anchor carrier to send SSBs and / or SIBs.

[0542] It is worth noting that: some embodiments include S4201, and the other steps are optional steps; for example, if the network device currently has no terminal that needs to be paged, the other steps can be omitted.

[0543] Some embodiments may include S4201 and S4202, and the other steps are optional. For example, if the network device sends the second information and the first information, but there is no paging demand at that time, then steps S4103 and S4104 may be omitted.

[0544] A cell supports multiple DL carriers, but when searching for a cell, a terminal only needs to search for or identify one DL carrier. This can reduce the number of frequencies that the terminal needs to search for a cell and improve cell search efficiency.

[0545] When a terminal camps on a frequency, it can see that multiple DL carriers belong to one cell.

[0546] The terminal receives broadcast system information and / or SSB on one DL carrier and monitors paging messages on one or more other DL carriers.

[0547] In some embodiments, an algorithm or network-side configuration is used to determine on which DL carrier the terminal receives paging and / or system broadcast.

[0548] The multiple DL carriers belonging to the same cell at the same time may be intra-band carriers or inter-band carriers.

[0549] At the same time, the system broadcast can be on one DL carrier. For example, the terminal can receive the configuration information of other carriers of the cell on the carrier of the cell searched.

[0550] If a cell broadcasts system information on one DL carrier, so that the terminal can search and identify the cell on that carrier, and sends a paging message on one or more other DL carriers, the terminal can support communication on one or more DL carriers.

[0551] Method 1: Display and directly determine the target cell to receive paging.

[0552] Option 1: carrier index = UE_ID mod M.

[0553] Option 2: carrier index = floor(UE_ID / N) mod M

[0554] Option 3: carrier index = floor(UE_ID / N / Ns) mod M

[0555] The UE_ID is calculated based on the 5G-S-TMSI, for example, 5G-S-TMSI mod 1024 or 5G-S-TMSI mod 4096. M is the number of valid carriers 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. The number of valid carriers here is the same as the number of the first carriers mentioned above.

[0556] In some embodiments, the carrier index is a carrier index.

[0557] The network side will configure which carriers can send paging messages.

[0558] The carrier index here may also be an index of the first carrier, and the index of the first carrier may also be referred to as a carrier index of the paging carrier (paging carrier index).

[0559] The carrier index of the first carrier (paging carrier index) is an index that can become the first carrier, that is, the carrier indexes that can become the first carrier are sequentially indexed from small to large.

[0560] Alternatively, the carrier index (paging carrier index) of the first carrier is an index configured by the network side for the first carrier.

[0561] Method 2: implicitly and directly determining the second carrier for sending the paging message. For example, PO or PF pulls numbers between various carriers, and indirectly determines the second carrier for sending the paging message by determining PO or PF.

[0562] The most typical scenario is that all carriers supporting paging (i.e., the first carrier) share a set of paging configurations (the paging configurations may also be referred to as paging configuration parameters). For example, in the same DRX cycle, there are the same number of PFs in a DRX cycle and the same number of POs in a PF.

[0563] Option 1: All PFs within a DRX cycle of all carriers supporting paging are numbered uniformly. For example, the PF numbers in Figures 3A and / or 3B 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:

[0564] Option a: number each carrier in the time domain from earliest to latest according to the carrier index (carrier index) or the first carrier index (paging carrier index) of the carrier supporting paging.

[0565] Option b: On all carriers that support paging, all PFs that support the first carrier 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 carrier index (carrier index) or the first carrier index (paging carrier index) of the cell that supports paging 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 of the initial downlink (DL) bandwidth part (BandWidth Part, BWP) of the carrier. Or it can be based on an order displayed and configured on the network side.

[0566] Based on the PF with the pass number, the terminal needs to determine the PF to receive the paging message.

[0567] The second carrier may be determined based on the total number of PFs and / or the UE_ID in at least one of the following ways:

[0568] PF index = UE_ID mod K, where K represents the total number of PFs in a DRX cycle. PF index == floor(UE_ID / M) mod K, where M represents the number of valid carriers capable of paging. K represents the total number of PFs in a DRX cycle.

[0569] PF index is the frame index, which can also be called the frame number.

[0570] The terminal determines the time domain position of the PF on a carrier based on the following formula: (SFN+PF_offset) mod T=n, where n=0, 1, 2, ..., N, and N is the number of PFs on a carrier in a DRX cycle.

[0571] Option 2: All POs of all PFs in a DRX cycle of all carriers that support paging are numbered uniformly. The PO numbers are PO 0, PO 1, PO 2, ..., P26. The principle of numbering all POs of all PFs in a DRX cycle of all carriers can be:

[0572] Option a: number each carrier in the time domain from earliest to latest according to the carrier index (carrier index) or the first carrier index (paging carrier index) of the carrier supporting paging.

[0573] Option b: On all carriers that support paging, all POs that support the first carrier 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 order of the carrier index that supports paging or the paging carrier index from small to large, or based on the order of the spectrum of the carrier 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.

[0574] Based on the POs with the same number, the terminal needs to determine the PO to receive the paging.

[0575] Based on the total number of POs, UE_ID is determined based on the following formula:

[0576] PO index = UE_ID mod X, where X represents the number of all POs after numbering within a DRX cycle. Or

[0577] PO index == floor(UE_ID / M) mod X, where M is the number of valid carriers capable of transmitting paging. X represents the number of all PFs numbered in a DRX cycle.

[0578] or

[0579] PO index == floor(UE_ID / M / N) mod X, where M is the number of valid carriers capable of transmitting paging. X represents the number of all numbered POs in a DRX cycle. N represents the number of PFs on a carrier in a DRX cycle.

[0580] PO index == floor(UE_ID / K) mod X, where M is the number of valid carriers capable of transmitting paging. X represents the number of all POs numbered in a DRX cycle. K represents the number of all PFs numbered in a DRX cycle.

[0581] The UE determines the time domain position of the PO on a carrier based on the following formula: (SFN+PF_offset) mod T=n, where n=0, 1, 2, ..., N.

[0582] N is the number of PFs on a carrier in a DRX cycle.

[0583] The terminal may also determine the PF of each carrier based on the different configuration modes provided in Mode 4. For example, the terminal may also determine the PF of each carrier if configured based on offset, step, gap, etc.

[0584] The terminal determines the time domain position of the PO on a carrier 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 (occasion index) of each PO.

[0585] Method 3: Determine the carrier for receiving paging based on the indication of LP-WUS.

[0586] If the anchor carrier supports LP-WUS and the terminal also supports LP-WUR, the network side indicates paging through LP-WUS and / or the carrier index of the paging reception.

[0587] The LP-WUS may include at least one of the following:

[0588] Option 1: The paging indication information indicates paging indication information for a group or subgroup, and the paging indication information is also associated with information identifying the carrier receiving the paging message. For example, the carrier information may include at least a carrier index. The LP-WUS may further indicate the PF and / or PO for receiving the paging message on the second carrier.

[0589] Option 2: The paging indication information indicates paging indication information for a group or subgroup, and the paging indication information is also associated with at least one carrier information identifying the carrier receiving the paging message, such as a carrier index. The terminal can determine the second carrier based on the UE_ID and information such as the total number of carriers receiving paging. The method for the terminal to determine the second carrier can refer to Method 1 or Method 2. The LP-WUS may further indicate the PF and / or PO for receiving the paging message on the second carrier.

[0590] The paging indication information here is the aforementioned first information.

[0591] Method 4: Paging configuration can be as follows:

[0592] Option 1: Paging is sent on the anchor carrier, and all carriers supporting paging share the same configuration parameters. Option 2: Each carrier supporting paging has its own paging configuration.

[0593] Option 3: Sending paging configuration on the anchor carrier: There is an offset between the PF of each carrier supporting paging transmission and the PF of the anchor carrier. For example, the offset is based on a network-side configuration.

[0594] Option 4: Paging configuration is sent on the anchor carrier. The PFs of carriers supporting paging are distributed with a specific step or gap starting from the anchor carrier's PF. This step or gap may depend on the network configuration. Carriers supporting paging are distributed with a step starting from the anchor carrier's PF in ascending order of carrier index. The step or gap may be an integer number of System Frame Numbers (SFNs).

[0595] Method 5: Use beam scanning to send paging DCI.

[0596] The beam sweeping method of other carriers is the same as the beam sweeping method of the anchor carrier (the carrier that assists in transmitting SSB and SIB1).

[0597] The disclosed embodiments provide a method for sharing paging calls across multiple carriers in a multi-carrier cell scenario. During paging, the UE determines which carrier to receive the paging call, thereby increasing paging capacity. Multi-carrier cells can be flexibly deployed and expanded on demand, improving the flexibility and timeliness of network deployment.

[0598] Supports the deployment of multi-carrier cells, using multiple carriers to increase the cell's paging capacity and reduce the paging load of the anchor carrier.

[0599] During the paging reception process, the carrier for receiving the paging is determined directly or indirectly, and the carrier for receiving the paging is determined with the assistance of LP-WUS.
