[0234] As shown in FIG. 1 a , 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 .

[0235] 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.

[0237] 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 Open RAN, and the processes and information interactions between these internal interfaces can be implemented through software or programs.

[0238] 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.

[0239] 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).

[0240] 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.

[0241] 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 a portion 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.

[0242] 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).

[0243] 3GPP standard Release 15 (R15) introduced the fifth generation (5G). 5G terminals consume very high energy. To achieve this, a number of terminal energy-saving technologies have been introduced, including Connected Discontinuous Reception (C-DRX), which is supported by both 4G and 5G, and measurement relaxation.

[0244] To further achieve terminal energy saving, R16 introduces a wake-up signal (WUS) for radio resource control (RRC) terminal energy saving. An offset before the UE C-DRX on-duration defines a duration for sending the WUS signal. During this WUS duration, the WUS signal, i.e., DCI 2-6, is sent and scrambled by the PS-RNTI to indicate whether the terminal should wake up during the next UE C-DRX on-duration to monitor the physical downlink control channel (PDCCH).

[0245] In Release 17, a paging WUS was introduced to save energy for terminals in the RRC idle state (RRC_IDLE) or RRC inactive state (RRC_INACTIVE). This WUS, also known as the Paging Early Indication (PEI), is sent sometime before the Paging Occasion (PO) to indicate whether the terminal is monitoring paging scheduling information at that PO. The PEI is DCI 2-7, scrambled by the Paging Early Indication Radio Network Temporary Identifier (PEI-RNTI).

[0246] As shown in Figure 1b, to further achieve terminal energy conservation, a low-power wake-up receiver (LP-WUR), also known as a low-power wake-up signal (LP-WUS), can be introduced. The base station can send an LP-WUS to the terminal to wake up the terminal when the main transceiver is asleep. Specifically, the main transceiver is asleep, and a separate low-power receiver is used to receive the LP-WUS. After receiving the LP-WUS, the low-power receiver can wake up the terminal's main receiver to perform data transmission and reception operations. The power consumption of the terminal's low-power receiver is much lower than that of the terminal's main receiver.

[0247] The system information block can be as shown in Figure 1c: SIB1 is configured with the scheduling information of other SIBs (such as SIB2 to SIB9), and the terminal receives the corresponding SIBs in the system information window (SI window). Among them, SIB7 and SIB8 are related to public warnings.

[0248] The change of system information is indicated by a short message in the DCI. The content of the short message indication is shown in Table (1). As shown in Table (1), bit 2 is used to indicate whether SIB2 to SIB9 has a public warning notification.

[0249] Table (1)

[0250] When the terminal receives a SIB containing a public warning notification (such as SIB7 and SIB8), it needs to first receive SIB1, and determine the system message window for receiving the SIB containing the public warning notification through SIB1, and then receive the SIB containing the public warning notification in the determined system message window, so there will be a delay in receiving the public warning notification. Or when the terminal receives a paging message, it needs to first receive the scheduling information of the paging message, and then receive the paging message based on the scheduling information. Whether receiving a public warning notification or a paging message, the terminal needs to first receive the SIB within the system information window, which will cause a delay in receiving the information.

[0620] Step S6101: The first access network device sends an LP-WUS to the terminal, wherein the LP-WUS carries first information, wherein the first information is used to indicate at least one of a first listening window, a second listening window and a public alarm notification, wherein the first listening window is used for the terminal to listen to the public alarm notification; and the second listening window is used for the terminal to listen to the paging message.

[0621] For optional implementation methods of step S6101, please refer to step S2103 of Figure 2a, step S2203 of Figure 2b, 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 and 5b, which will not be repeated here.

[0622] The following provides a specific example in combination with any of the above embodiments:

[0623] Solution 1: LP-WUS indicates a temporary system information window (SI-window) for receiving system information (SI).

[0624] The terminal receives an LP-WUS, which carries an indication message indicating an ETWS and / or CMAS alert notification, and / or the starting position of the SI-window for receiving the ETWS and / or CMAS alert notification, and / or the length of the SI-window. The length of the SI-window can also be configured through a system message.

[0625] Option 1: The starting position of the SI-window may be an offset relative to the LP-WUS receiving position, for example, the offset may be several slots, or several symbols, or several subframes.

[0626] Option 2: The starting position of the SI-window may be a system frame number (SFN), and / or a subframe number, and / or a slot number.

[0627] The terminal is within the SI-window:

[0628] Option a: Receive SI scheduling information within the SI-window, i.e., DCI scrambled by the SI-RNTI, then receive the PDSCH, and then receive the SIB. The PDCCH occasions within the SI-window are numbered starting from 0 and correspond one-to-one with the actual transmitted SSB index in ascending order.

[0629] Option b: The SI-window provided in the LP-WUS is the time domain position of the PDSCH corresponding to the received SI. The frequency domain position is based on the LP-WUS configuration or pre-configured in the system message. The modulation and coding scheme of the SI are pre-configured through system broadcast or based on protocol agreement.

[0630] Solution 2: LP-WUS indicates a temporary SI-window for receiving paging (hereinafter referred to as window).

[0631] The terminal receives an LP-WUS, which carries an indication indicating the starting position of the window for receiving paging DCI and / or the length of the window. The length of the window can also be configured through system messages. The LP-WUS also indicates the PO index.

[0632] Option 1: The starting position of the window may be an offset relative to the LP-WUS receiving position, for example, the offset may be a number of slots, a number of symbols, or a number of subframes.

[0633] Option 2: The starting position of the window may be an SFN number, and / or a subframe number, and / or a slot number.

[0634] The terminal is in the window:

[0635] Option a: Receive the paging scheduling information (i.e., the P-RNTI-scrambled DCI) within the window, then receive the PDSCH, and then receive the paging message. Occasions within the window are numbered starting from 0 and correspond one-to-one with the actual transmitted SSB index in ascending order.

[0636] Option b: The window specified in the LP-WUS is the time domain location of the PDSCH corresponding to the paging message. The frequency domain location is based on the LP-WUS configuration or pre-configured in the system message. The modulation and coding scheme of the paging message are pre-configured through system broadcast or based on protocol agreement.

[0637] Before receiving LP-WUS related to paging message:

[0638] (1) For UEs in RRC idle state (RRC_IDLE), i.e., in the CN paging scenario, the AMF sends information about the UE's support for LP-WUS capability to the base station (e.g., gNB). The base station decides whether to use LP-WUS notification for paging reception, or a traditional paging transmission method, such as PEI, or paging DCI, based on the UE's capability.

[0639] (2) For the RAN paging scenario, the anchor base station knows that the UE supports the LP-WUS capability. The anchor base station sends the UE's support of the LP-WUS capability to other base stations in the RNA through the RAN paging message via the Xn interface. The base station decides whether to use the LP-WUS notification paging reception method, the traditional paging transmission method such as PEI, or the paging DCI method based on the UE's capabilities.

[0640] Based on the LP-WUS indication, a temporary SI-window is used to receive public warning notifications. The temporary window receives the paging DCI of the specified PO, which reduces the delay in receiving public warning information and the delay in receiving paging.
