[0232] FIG1 is a schematic diagram showing the architecture of a communication system according to an embodiment of the present disclosure.

[0233] As shown in FIG1 , a communication system 100 includes a terminal 101 , a first access network device 102 , a second access network device 103 , and a core network device 104 .

[0234] 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.

[0236] In some embodiments, the technical solution of the present disclosure can be applied 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 can be transformed into internal interfaces of the Open RAN, and the processes and information interactions between these internal interfaces can be implemented through software or programs.

[0237] 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.

[0238] In some embodiments, the core network device 104 includes, for example, at least one of an Evolved Packet Core (EPC), a 5G Core Network (5GCN), and a Next Generation Core (NGC).

[0239] 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 solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution 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 solution provided by the embodiment of the present disclosure is also applicable to similar technical problems.

[0240] The following embodiments of the present disclosure may be applied to the communication system 100 shown in Figure 1, or a portion thereof, but are not limited thereto. The entities shown in Figure 1 are illustrative only. The communication system may include all or part of the entities shown in Figure 1, or may include other entities outside of Figure 1. 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.

[0241] 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 information transmission methods, and next-generation systems based on and extending these systems. Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0242] 5G technology was introduced in 3GPP standard Release 15 (R15). 5G base stations consume four times more energy than Long Term Evolution (LTE) base stations, making network energy conservation an important means for operators to reduce the cost of operating 5G systems.

[0243] In 3GPP standard release 16 (R16), a wake-up signal (WUS) was introduced to save energy for user equipment (UE) in Radio Resource Control (RRC) connected state. A monitoring period (duration) for sending the WUS signal is defined by an offset value before the UE's connected discontinuous reception (C-DRX) on duration. During this WUS monitoring duration, the WUS signal, i.e., DCI 2-6, is sent and scrambled with the Power Saving Radio Network Temporary Identity (PS-RNTI). It is used to indicate whether the UE should wake up to monitor the Physical Downlink Control Channel (PDCCH) during the next UE C-DRX on duration.

[0244] In 3GPP standard release 17 (R17), a paging wake-up signal (Paging WUS) was introduced to save energy for UEs in RRC idle / RRC inactive states. The Paging WUS, also known as the Paging Early Indication (PEI), is sent sometime before the Paging Occasion (PO) to indicate whether the UE is monitoring paging scheduling information at that PO. The PEI is DCI 2-7, scrambled by the Paging Early Indication Radio Network Temporary Identity (PEI-RNTI).

[0245] In 3GPP Release 18 (R18), the Network Energy Saving (NES) project was launched to reduce network energy consumption. The standard supports four NES functions:

[0246] SSB-less SCell

[0247] Cell discontinuous transmission / reception (cell DTX / DRX);

[0248] Antenna port adaptation;

[0249] Physical downlink shared channel transmission power adaptation (PDSCH transmission power adaptation).

[0250] In a DRX cycle, a UE only needs to monitor one paging occasion. A paging frame is a radio frame that contains the starting positions of one or more paging occasions.

[0251] The paging frame (PF) satisfies the following expression: (SFN+PF_offset) mod T = (T div N) * (UE_ID mod N)

[0252] The paging occasion (PO) is determined by the following expression: i_s = floor (UE_ID / N) mod Ns

[0253] Where T represents the DRX cycle obtained according to the minimum principle (i.e., the smallest of the default DRX cycle, the Radio Access Network (RAN) DRX cycle, and the UE-specific DRX cycle); N represents the number of paging frames in the DRX cycle; Ns represents the number of POs in the PF; PF_offset represents the offset that determines the PF; and UE_ID represents the Temporary Mobile Subscriber Identity (TMSI) mod 1024.

[0254] Therefore, from the perspective of the cell, there are multiple PFs in one DRX cycle, multiple POs in each PF, and each PO schedules paging messages in a beam sweeping manner.

[0255] In existing technologies, each DRX cycle has multiple PFs, which are discrete within the DRX cycle. However, each PF can have multiple POs configured on the network side, and these POs can also be discrete. Discrete PFs and POs can cause access network devices to constantly wake up and send possible paging requests.

[0256] How to configure paging to reduce the number of times access network devices wake up due to discrete PFs and discrete POs is an urgent problem to be solved.

[0257] FIG2a is an interactive diagram illustrating an information transmission method according to an embodiment of the present disclosure. As shown in FIG2a, the present disclosure embodiment relates to an information transmission method for a communication system 100, the method comprising:

[0258] Step S2101: The terminal sends the fourth information.

[0259] In some embodiments, the terminal sends fourth information to the core network device, wherein the fourth information is used to indicate a PO scheduling mode that the terminal can use and / or a PO scheduling mode that the terminal wants to use.

[0260] In some embodiments, the terminal may send the fourth information to the core network device in the RRC connected state.

[0261] In some embodiments, the core network device includes an access and mobility management function (AMF). Optionally, the UE carries the fourth information to the AMF through NAS signaling, for example, through a registration request (REGISTRATION REQUEST) message.

[0262] In some embodiments, the core network device may save the PO scheduling methods that the terminal can use and / or the PO scheduling methods that the terminal wants to use.

[0263] In some embodiments, terms such as "hope", "expect", and "willing" can be used interchangeably.

[0264] In some embodiments, the PO scheduling type that the terminal wishes to use may be the PO scheduling type with the highest priority selected by the terminal.

[0265] In some embodiments, the PO scheduling method includes at least the following: a first PO scheduling method; a second PO account transfer method; a third PO scheduling method.

[0266] In some embodiments, a first PO scheduling method includes: setting a PO in at least one discrete first PF in a cell DRX cycle, wherein Ns POs are set in one first PF, where Ns is an integer greater than or equal to 1. As shown in Figure 2b, a cell DRX cycle has multiple discrete first PFs. One first PF has Ns POs.

[0267] In one embodiment, the first PF may be network configured.

[0268] In one embodiment, the first PF may be agreed upon by a communication protocol.

[0269] In some embodiments, the system frame number of the first PF satisfies the following expression: (SFN+PF_offset) mod T = (T div N) * (UE_ID mod M)

[0270] The PO in the first PF is determined by the following expression: i_s=floor(UE_ID / N)mod Ns

[0271] Among them, T represents the cell DRX cycle; M represents the number of first PFs in the DRX cycle; Ns represents the number of POs in the first PF; PF_offset represents the offset for determining the first PF; UE_ID is the remainder obtained by dividing the temporary mobile subscriber identity (TMSI) by 1024.

[0275] In some embodiments, the PO in the second PO scheduling method is determined based on the first PO scheduling method.

[0277] In some embodiments, among the consecutive P PFs starting from the second PF, the number of POs of each PF is different from Ns.

[0278] As shown in Figure 2c, all POs in all first PFs within a cell DRX cycle shown in Figure 2b can be set in P consecutive PFs starting from the second PF. The access network device and / or terminal only needs to wake up in the P consecutive PFs, and no longer needs to wake up in multiple discrete first PFs as shown in Figure 2b.

[0281] In some embodiments, in the third PO scheduling method, Ns is the number of POs set in the first PF in the first scheduling method.

[0282] In some embodiments, in the third PO scheduling method, Ns is the number of POs set in the second PF in the second scheduling method.

[0283] In some embodiments, the number of POs in a PF may be increased to reduce the number of PFs, thereby reducing the probability of waking up the access network device and / or the terminal.

[0284] In some embodiments, eNs may be carried in a separate IE.

[0285] In some embodiments, eNs takes a value of {8, 16, 32, 64}.

[0286] In some embodiments, when both Ns and eNs exist, a terminal supporting eNS may ignore Ns and use eNs.

[0287] In some embodiments, when both Ns and eNs exist, a terminal that supports NS may ignore eNs.

[0288] In some embodiments, the PO scheduling method may be specified by a communication protocol.

[0289] In some embodiments, the PO scheduling method can be configured by a network device, such as a core network device.

[0290] Step S2102: The core network device sends the second information.

[0291] In some embodiments, the core network device sends second information to the first access network device. Optionally, the second information is used to indicate a PO scheduling method that the terminal can use and / or a PO scheduling method that the terminal desires to use. In some embodiments, the PO scheduling method includes at least one of the following: a first PO scheduling method; a second PO account transfer method; and a third PO scheduling method.

[0292] Any one of the first PO scheduling method, the second PO account transfer method and the third PO scheduling method is similar to that in step S2101 and will not be described again here.

[0293] In some embodiments, the second information can be used by the first access network device to determine the PO scheduling method adopted by the first access network device.

[0294] In some embodiments, the PO scheduling method used by the first access network device is at least one of the following:

[0295] PO scheduling methods that can be used by the terminal;

[0296] The PO schedule that the terminal wishes to use.

[0297] In some embodiments, the second information is carried in an NG paging message.

[0298] In some embodiments, when the core network device initiates core network paging (CN paging) to the terminal, it sends an NG paging message carrying the second information to the first access network device. The NG interface is the interface between the core network device and the access network device.

[0299] Step S2103: The first access network device sends the first information.

[0300] In some embodiments, the first access network device sends first information to the terminal.

[0301] In some embodiments, the first information is used to indicate a paging occasion PO scheduling method adopted by the first access network device.

[0302] In some embodiments, the first information is carried in broadcast information of the first access network device.

[0303] In some embodiments, the first information is carried in a system message of the first network-connected device and broadcast.

[0304] In some embodiments, the first information explicitly indicates the paging occasion PO scheduling mode adopted by the first access network device. For example, the first access network device indicates different PO scheduling modes through different values.

[0305] In some embodiments, the first information implicitly indicates a paging occasion PO scheduling mode adopted by the first access network device. For example, the first information is used to indicate configuration parameters corresponding to the PO scheduling mode, and should instruct the first access network device to adopt the PO scheduling mode.

[0306] In some embodiments, the PO scheduling method includes at least the following: a first PO scheduling method; a second PO account transfer method; a third PO scheduling method.

[0307] Any one of the first PO scheduling method, the second PO account transfer method and the third PO scheduling method is similar to that in step S2101 and step S2102, and will not be repeated here.

[0308] In some embodiments, the mapping relationship between the PDCCH occasion associated with PO and the SSB in the second PO scheduling method is specified by the communication protocol.

[0309] In some embodiments, the mapping relationship between the PDCCH occasion associated with PO and the SSB in the second PO scheduling mode is configured by a network device (such as a core network device or an access network device).

[0310] In some embodiments, the second PO scheduling method includes: setting all POs in all the first PFs in the DRX cycles of the N cells in the consecutive P PFs in sequence according to the time domain position of each PO in the first PF. In the second PO scheduling method, the time domain position order of all POs can be the time domain position order of POs in the first PO scheduling method.

[0311] In some embodiments, the PO-associated PDCCH opportunity includes: a PDCCH opportunity including the PO.

[0312] In some embodiments, the PO is a PO with paging information.

[0313] In some embodiments, the access network equipment may map the PDCCH opportunities associated with the POs having paging information, and not map the PDCCH opportunities associated with the POs not having paging information.

[0314] In some embodiments, the access network device allocates a PDCCH opportunity for a PO with paging information, and does not allocate a PDCCH opportunity for a PO without paging information.

[0315] In some embodiments, a paging early indication (PEI) indicates a PO with paging information and does not indicate a PO without paging information.

[0316] For example, there are 4 POs, three of which have paging information, and one has no paging information requirement to be sent. In this case, the PO without paging information requirement will not be considered when mapping the PDCCH timing and SSB, that is, the PDCCH timing resources will not be reserved for this PO without paging requirement.

[0317] In some embodiments, for the second PO scheduling method, all POs in the DRX cycles of the N cells are numbered in order of their time domain positions (i.e., the natural number sequence of the PO is determined), and the PO-associated PDCCH and SSB are mapped based on the number.

[0318] In some embodiments, in the second PO scheduling mode, the x-th PO-associated PDCCH opportunity among all POs in the DRX cycles of the N cells and the SSB satisfy the following relationship:

[0319] The x*S+Kth PDCCH opportunity corresponds to the Kth SSB of the xth PO;

[0320] Wherein, x represents the natural number sequence number of each PO determined by sorting all POs in the DRX cycles of the N cells in time domain order; K represents the index number of the SSB; S represents the total number of SSBs actually transmitted by the first access network device, and N is an integer greater than or equal to 1. x can start from 0, and K can start from 0. K can be 0, 1, or S-1.

[0321] In some embodiments, the x*S+Kth PDCCH opportunity corresponds to the Kth SSB of the xth PO, and the x*S+Kth PDCCH opportunity may have a mapping relationship with the Kth SSB of the xth PO.

[0322] In some embodiments, the first access network device maps the x*S+Kth PDCCH opportunity to the Kth SSB of the xth PO.

[0323] In some embodiments, the natural number sequence (or serial number) of each PO in the second PO scheduling method can be determined by sorting the time domain position of each PO in the first PO scheduling method from first to last.

[0324] In some embodiments, the second PF is the first PF where the PDCCH opportunity associated with the PO is located.

[0325] Exemplarily, all PDCCH opportunities associated with POs are numbered starting from 0 within P consecutive PFs starting from the second PF, and all POs in the N DRX cycles of the cell are uniformly numbered x, starting from 0. The first S consecutive PDDCH opportunities correspond to the first PO, the second S consecutive PDDCH opportunities correspond to the second PO, and so on. Within a PO, the first PDCCH opportunity corresponds to the first SSB index, and so on.

[0326] In some embodiments, for the second PO scheduling method, all POs within each first PF are numbered in order of time domain position (i.e., the natural number sequence of the PO within each first PF), and the PO-associated PDCCH and SSB are mapped based on the number.

[0327] In some embodiments, for the second PO scheduling mode, the xth PO-associated PDCCH opportunity in the mth first PF and the SSB satisfy the following relationship:

[0328] The m*Ns*S+x*S+Kth PDCCH opportunity corresponds to the Kth SSB of the xth PO in the mth first PF,

[0329] Wherein, m represents the natural number sequence number of the first PF determined by sorting all PFs in the DRX cycle of the cell in order of their time domain positions;

[0330] x represents the natural number sequence number of each PO determined by sorting the POs in the first PF in time domain order; K represents the index number of the SSB; and S represents the total number of SSBs actually transmitted by the first access network device. x can start at 0, and K can start at 0. K can range from 0, 1, to S-1.

[0331] In some embodiments, the m*Ns*S+x*S+Kth PDCCH opportunity corresponds to the Kth SSB of the xth PO in the mth first PF, and the m*Ns*S+x*S+Kth PDCCH opportunity may have a mapping relationship with the Kth SSB of the xth PO in the mth first PF.

[0332] In some embodiments, the first access network device maps the m*Ns*S+x*S+Kth PDCCH opportunity to the Kth SSB of the xth PO in the mth first PF.

[0333] Exemplarily, all PDCCH occasions associated with POs are numbered starting from 0 within the second PF. The first consecutive Ns*S PDCCH occasions correspond to the first PF (first first PF), the second consecutive Ns*S PDCCH occasions correspond to the second PF (second first PF), and so on. S is the number of SSBs actually transmitted. Ns is the number of POs within a PF. Exemplarily, within a PF, the first consecutive S PDDCH occasions correspond to the first PO, the second consecutive S PDDCH occasions correspond to the second PO, and so on. Within a PO, the first PDCCH occasion corresponds to the first SSB index, and so on.

[0334] In some embodiments, for the second PO scheduling method, all POs in each first PF in each cell DRX cycle are numbered in order of time domain position (i.e., the natural number sequence of PO in each first PF in different cell DRX cycles), and the PO-associated PDCCH and SSB are mapped based on the number.

[0335] In some embodiments, for the second PO scheduling mode, the xth PO-associated PDCCH opportunity of the mth first PF in the nth DRX cycle of the cell satisfies the following relationship with the SSB:

[0336] The n*M*Ns*S+m*Ns*S+x*S+Kth PDCCH opportunity corresponds to the Kth SSB of the xth PO of the mth first PF in the nth DRX cycle of the cell;

[0337] Wherein, n represents the natural number sequence number of each cell DRX cycle determined by sorting in time domain position order within the cell DRX cycle; m represents the natural number sequence number of the first PF determined by sorting all PFs in the nth cell DRX cycle by time domain position order; M represents the number of first PFs included in the nth cell DRX cycle; x represents the natural number sequence number of each PO in the first PF determined by sorting in time domain position order; K represents the index number of the SSB; S represents the total number of SSBs actually transmitted by the first access network device. x can start from 0, and K can start from 0. K can be 0, 1..S-1.

[0338] In some embodiments, the n*M*Ns*S+m*Ns*S+x*S+Kth PDCCH opportunity corresponds to the Kth SSB of the xth PO of the mth first PF in the nth DRX cycle of the cell, and the n*M*Ns*S+m*Ns*S+x*S+Kth PDCCH opportunity may have a mapping relationship with the Kth SSB of the xth PO of the mth first PF in the nth DRX cycle of the cell.

[0339] In some embodiments, the first access network device maps the n*M*Ns*S+m*Ns*S+x*S+Kth PDCCH opportunity to the Kth SSB of the xth PO of the mth first PF in the nth DRX cycle of the cell.

[0340] For example, all DRX cycles are numbered starting from 0, and all first PF numbers in each DRX cycle are numbered starting from 0. M represents the first PF number of a DRX cycle. m can be: 0, 1...M-1.

[0341] Exemplarily, all PO-associated PDCCH opportunities are numbered starting from 0 in the second PF. The first consecutive Ns*S*M PDCCH opportunities correspond to the PDCCH resources of the first DRX cycle, the second consecutive Ns*S*M PDCCH opportunities correspond to the PDCCH resources of the second DRX cycle, and so on. S is the number of SSBs actually transmitted. In a DRX cycle, the first consecutive Ns*S PDCCH opportunities correspond to the first PF, the second consecutive Ns*S PDCCH opportunities correspond to the second PF, and so on. S is the number of SSBs actually transmitted. Ns is the number of POs in a PF. In a PF, the first consecutive S PDDCH opportunities correspond to the first PO, the second consecutive S PDDCH opportunities correspond to the second PO, and so on. In a PO, the first PDCCH opportunity corresponds to the first SSB index, and so on.

[0342] In some embodiments, in the second PO scheduling method, the time domain position order of the POs that the terminal needs to monitor can be determined based on the time domain position order of the POs that the terminal needs to monitor in the first PO scheduling method.

[0343] In some embodiments, in the first PO scheduling method, the natural number sequence of the PO that the terminal needs to monitor among all POs sorted by time domain position is associated with the natural number sequence of the PO that the terminal needs to monitor among all POs sorted by time domain position in the second PO scheduling method.

[0344] For example, in the first PO scheduling method, all terminals in PO need to listen to the second PO sorted by time domain position (PO natural number is 1), then in the second PO scheduling method, all terminals in PO need to listen to the second PO sorted by time domain position (PO natural number is 1).

[0345] In some embodiments, the natural number sequence number of the PO that the terminal needs to monitor in the first PO scheduling mode is determined based on the first PF that the terminal needs to monitor and the natural number sequence number of the PO in the first PF.

[0615] FIG6 is an interactive diagram illustrating an information transmission method according to an embodiment of the present disclosure. As shown in FIG6 , the present disclosure embodiment relates to an information transmission method for a communication system 100, and the method includes one of the following steps:

[0616] Step S6101: The first access network identifies and sends first information to the terminal, wherein the first information is used to indicate the PO scheduling method adopted by the first access network device.

[0617] For optional implementation methods of step S5101, please refer to step S2104 of Figure 2a, step S2204 of Figure 2d, step S3102 of Figure 3a, step S3202 of Figure 3b, step S4102 of Figure 4a, step S4202 of Figure 4b and other related parts in the embodiments involved in Figures 2a, 2b, 3a, 3b, 3c, 4a to 4e, 5a, 5b and 6, which will not be repeated here.

[0618] The following provides a specific example in combination with any of the above embodiments:

[0619] The system broadcasts explicit configuration or implicit configuration, indicating which paging method (such as PO scheduling method) the current cell adopts: traditional paging method (first PO scheduling method), cascaded PO method (second PO scheduling method), or extended Ns IE method (third PO scheduling method).

[0620] Solution 1: Paging window definition.

[0621] The cascaded POs can be:

[0622] Option 1: All POs of all PFs in one DRX cycle are concatenated together.

[0623] In mode A, the protocol stipulates or the network side configures the PF number of a DRX cycle as the starting PF of the cascaded PO, that is, starting from this PF, the subsequent PDCCH occasions are numbered from 0.

[0624] All POs of all PFs in the DRX cycle are numbered uniformly starting from 0. The mapping relationship between all cascaded POs and SSBs is: the [x*S+K]th PDCCH opportunity corresponds to the Kth SSB of the xth PO. Where S is the number of SSBs actually transmitted, x is the number index of all POs of all PFs in the DRX cycle, which are uniformly numbered starting from 0, and K is the index of the number of SSBs transmitted at the opportunity, starting from 0.

[0625] Specifically, all valid PDCCH opportunities are numbered starting from 0 within the target PF, and all POs of all PFs are numbered uniformly, starting from 0. The first S consecutive PDCCH opportunities correspond to the first PO, the second S consecutive PDCCH opportunities correspond to the second PO, and so on. Within a PO, the first PDCCH opportunity corresponds to the first SSB index, and so on. S is the number of SSBs actually transmitted.

[0626] After the UE calculates its own PF and PO, it determines the PO index in the cascaded PO based on the PF index and PO index, for example, the cascaded PO index = PF index * Ns + PO index, and determines the PDCCH timing based on the SSB index of the measured good beam, and then receives the paging scheduling information.

[0627] Where Ns is the total number of POs within a PF, and the PF index is 0, 1, 2, ..., N, where N is the total number of PFs in the DRX cycle. The PO index is i_s calculated by the UE. The UE calculates the PF and PO index using the following formula.

[0628] The SFN of the PF satisfies the following expression: (SFN+PF_offset) mod T = (T div N) * (UE_ID mod N);

[0629] The index i_s of the PO is determined by the following expression: i_s=floor(UE_ID / N)mod Ns;

[0630] Where T represents the minimum DRX cycle (i.e., the smallest of the default DRX cycle, the Radio Access Network (RAN) DRX cycle, and the UE-specific DRX cycle); N represents the number of paging frames in the DRX cycle; Ns represents the number of POs in the PF; PF_offset represents the offset used to determine the PF; UE_ID represents the Temporary Mobile Subscriber Identity (TMSI) mod 1024;

[0631] Method B numbers all PFs in the DRX cycle starting from 0, and the [m*Ns*S+x*S+K]th PDCCH opportunity corresponds to the Kth SSB of the xth PO of the mth first PF. Where S is the number of SSBs actually transmitted, x is the number index of all POs of a PF starting from 0, and K is the index of the number of SSBs transmitted at the opportunity, starting from 0.

[0632] Specifically, all valid PDCCH opportunities are numbered starting from 0 within the target PF. The first consecutive Ns*S PDCCH opportunities correspond to the first PF, the second consecutive Ns*S PDCCH opportunities correspond to the second PF, and so on. S is the number of SSBs actually transmitted. Ns is the number of POs within a PF.

[0633] In a PF, the first S consecutive PDCCH opportunities correspond to the first PO, the second S consecutive PDCCH opportunities correspond to the second PO, and so on. In a PO, the first PDCCH opportunity corresponds to the first SSB index, and so on.

[0634] After the UE calculates its own PF and PO, it determines the PDCCH timing based on the PF index and PO index, and the SSB index of the measured good beam, and then receives the paging scheduling information.

[0635] Where Ns is the total number of POs within a PF, and the PF index is 0, 1, 2, ..., N, where N is the total number of PFs in the DRX cycle. The PO index is i_s calculated by the UE. The UE calculates the PF and PO index using the following formula.

[0636] The SFN of the PF satisfies the following expression: (SFN+PF_offset) mod T = (T div N) * (UE_ID mod N);

[0637] The index i_s of the PO is determined by the following expression: i_s=floor(UE_ID / N)mod Ns;

[0638] In the above expression, the parameters are as described in method A and will not be repeated here.

[0639] Option 2: All POs of all PFs for n consecutive DRX cycles are concatenated together.

[0640] The protocol stipulates or the network side configures a long window L, which is an integer multiple of the DRX cycle. Therefore, the protocol stipulates or the network side configures an N, indicating that the cascaded PO is the cascade of all POs of all PFs for N DRX cycles.

[0641] For example, the PF of a cascaded PO is determined by: (SFN+PF_offset) mod L = offset or (SFN+PF_offset) mod N*T = offset

[0642] Where offset is an offset configured on the network side, T is the DRX cycle, and L is the long window length.

[0643] The DRX mentioned above is the default cell DRX of the cell or a DRX configured by the network side for cascade PO (system broadcast configuration).

[0644] All DRX cycles are numbered starting from 0. All PFs within each DRX are numbered starting from 0. The [n*M*Ns*S+m*Ns*S+x*S+K]th PDCCH opportunity corresponds to the Kth SSB of the xth PO of the mth first PF of the nth DRX cycle, for a total of M PFs. Where S is the number of SSBs actually transmitted, x is the index of all POs of a PF numbered uniformly starting from 0, and K is the index of the number of SSBs actually transmitted, starting from 0. Ns is the total number of POs within a PF.

[0645] Specifically, all valid PDCCH opportunities are numbered starting from 0 within the target PF. The first consecutive Ns*S*M PDCCH opportunities correspond to the PDCCH resources of the first DRX cycle, the second consecutive Ns*S*M PDCCH opportunities correspond to the PDCCH resources of the second DRX cycle, and so on. S is the number of SSBs actually transmitted. Ns is the number of POs within a PF. M is the number of PFs within a DRX cycle.

[0646] In a DRX cycle, the first consecutive Ns*S PDCCH opportunities correspond to the first PF, the second consecutive Ns*S PDCCH opportunities correspond to the second PF, and so on. S is the number of SSBs actually transmitted. Ns is the number of POs within a PF.

[0647] In a PF, the first S consecutive PDCCH opportunities correspond to the first PO, the second S consecutive PDCCH opportunities correspond to the second PO, and so on. In a PO, the first PDCCH opportunity corresponds to the first SSB index, and so on.

[0648] After the UE calculates its own DRX cycle index, PF and PO, it determines the PDCCH timing based on the PF index and PO index, and the SSB index of the measured good beam, and then receives the paging scheduling information.

[0649] Where Ns is the total number of POs within a PF, and the PF index is 0, 1, 2, ..., N, where N is the total number of PFs in the DRX cycle. The PO index is i_s calculated by the UE. The UE calculates the PF and PO index using the following formula.

[0650] The SFN of the PF satisfies the following expression: (SFN+PF_offset) mod T = (T div N) * (UE_ID mod N);

[0651] The index i_s of the PO is determined by the following expression: i_s=floor(UE_ID / N)mod Ns;

[0652] In the above expression, the parameters are as described in method A and will not be repeated here.

[0653] Solution 2: For RRC idle state terminals, namely RRC_IDLE UE

[0654] The UE carries the indication information that the terminal supports the cascaded PO function to the AMF through NAS signaling, for example, through the REGISTRATION REQUEST message. The AMF maintains the capability information. Optionally, the UE also indicates to the AMF through the NAS signaling whether it is willing to enable the cascaded PO function. When a CN paging is triggered, the CN carries the UE's capability indication information that it supports cascaded PO and / or the indication information that it is willing to use the cascaded PO function to the base station through the NG paging message. Based on the UE capability and / or willingness indication information, the base station decides whether to send paging to the terminal in the cascaded PO manner or in the traditional manner.

[0655] Solution 3: For RRC_INACTIVE UE

[0656] After the UE enters the connected state, the base station learns the UE's capability indication information of supporting cascaded PO and / or the indication information of willingness to use the cascaded PO function through CN push. When the UE enters the RRC_INACTIVE state, the anchor base station (the base station that saves the UE AS context) saves the above capability information and / or willingness indication information. When DL data reaches the anchor base station, it triggers the anchor base station to send RAN paging. At this time, the anchor base station carries the UE's capability indication information of supporting cascaded PO and / or the indication information of willingness to use the cascaded PO function through Xn paging (that is, RAN paging), instructing other base stations in the RNA to send paging to the RRC_INACTIVE UE. Based on the UE capability and / or willingness indication information, the base station decides whether to send paging to the terminal in a cascaded PO manner or to use the traditional method to send paging.

[0657] Solution 4: Resource Mapping for PEI of Cascading PO

[0658] The existing PEI (paging early indication) can indicate the PEIs of multiple POs. For the PEI of multiple POs, it can indicate whether each PO is sent for a cascaded PO. For POs that have no transmission, they can be skipped in Scheme 1, and PDCCH timing and SSB mapping are not reserved. For example, there are 4 POs, of which three have paging requirements and one has no paging requirements to be sent. In this case, the PO without paging requirements will not be considered in the PDCCH timing and SSB mapping, that is, PDCCH timing resources will not be reserved for this PO without paging requirements. In other words, all POs in Scheme 1 are POs that have further transmission requirements.

[0659] DCI format 2_7 is used to notify one or more UEs of paging early indication and TRS availability indication.

[0660] The following information is sent via DCI format 2_7, where the CRC is scrambled by the PEI-RNTI:

[0661] -Paging indication field;

[0662] - is the number of paging configured by the higher layer parameter po-NumPerPEI defined in clause 10.4A of [5, TS 38.213];

[0663] - The number of subgroups of paging occasions configured by the higher layer parameter subgroupsNumPerPO.

[0664] Each bit in the -field indicates a UE subgroup for the paging occasion.

[0665] - TRS availability indication – 1, 2, 3, 4, 5 or 6 bits, where the number of bits is equal to 1 plus the highest value of all indBitIDs provided by TRS ResourceSetConfig (if configured); otherwise, 0 bit.

[0666] Solution 5: Expand the value of Ns.

[0667] In order to directly cascade the PO effect, you can expand the Ns value and configure a PF.

[0668] Configure a new IE Ns with a value of {8, 16, 32, 64}.

[0669] For terminals that support this extended IE, such as R19 terminals, if this new IE is configured, the previously configured Ns will be ignored.

[0670] For legacy UEs that do not support this extended IE, only the originally configured Ns is seen and only this Ns is used to calculate PO.

[0671] Expand Ns as shown in "nsetx" in the following code:

[0672] All valid PDCCH opportunities are numbered starting from 0 within the target PF. All POs of the target PF are numbered uniformly, starting from 0. The first S consecutive PDCCH opportunities correspond to the first PO, the second S consecutive PDCCH opportunities correspond to the second PO, and so on. Within a PO, the first PDCCH opportunity corresponds to the first SSB index, and so on. S is the number of SSBs actually transmitted.

[0673] After the UE calculates its own PF and PO, it determines the PO index in the cascaded PO based on the PF index and PO index, for example, the cascaded PO index = PF index * Ns + PO index, and determines the PDCCH timing based on the measured SSB index of the good beam, and then receives the paging scheduling information.

[0674] Where Ns is the total number of POs within a PF. PF indices are 0, 1, 2, ..., N, where N is the total number of PFs in the DRX cycle. The PO index is i_s calculated by the UE. The UE calculates the PF and PO index using the following formula.

[0675] The SFN of the PF satisfies the following expression: (SFN+PF_offset) mod T = (T div N) * (UE_ID mod N);

[0676] The index i_s of the PO is determined by the following expression: i_s=floor(UE_ID / N)mod Ns;

[0677] In the above expression, the parameters are as described in method A and will not be repeated here.

[0678] For all the above schemes, valid PDCCH opportunities mean that the PDCCH monitoring opportunities for paging that do not overlap with UL symbols (determined according to tdd UL DL ConfigurationCommon) are numbered sequentially starting from zero starting from the first PDCCH monitoring occasion for paging in the PF.
