The terminal device can also be referred to as a terminal or a UE, and those skilled in the art can understand its meaning.

[0036] The access network device 20 is a device deployed in an access network to provide wireless communication functions for the terminal device 10. The access network device 20 can include various forms of macro base stations, micro base stations, relay stations, access points, and the like. In systems using different wireless access technologies, the names of devices with access network device functions can be different, for example, in a 5G NR system, it is called gNodeB or gNB. As communication technology evolves, the name of the "access network device" may change. For ease of description, in the embodiments of the present application, the above-mentioned devices that provide wireless communication functions for the terminal device 10 are collectively referred to as access network devices. In some embodiments, through the access network device 20, a communication relationship can be established between the terminal device 10 and the core network element 30. Illustratively, in the LTE (Long Term Evolution) system, the access network device 20 can be an EUTRAN (Evolved Universal Terrestrial Radio Access Network) or one or more eNodeBs in the EUTRAN; in the 5G NR system, the access network device 20 can be a RAN (Radio Access Network) or one or more gNBs in the RAN.

[0040] In the embodiments of the present application, a network device can provide services for a cell, and a terminal device communicates with the network device through transmission resources (for example, frequency domain resources, or spectrum resources) on a carrier used by the cell. The cell can be a cell corresponding to the network device (for example, a base station), and the cell can belong to a macro base station or a base station corresponding to a small cell (Small cell). The small cell can include a metro cell, a micro cell, a pico cell, a femto cell, and the like. These small cells have the characteristics of small coverage and low transmit power, and are suitable for providing high-speed data transmission services.

[0041] Before introducing the technical solutions of the present application, the related technologies involved in the present application are introduced and explained. The following related technologies can be combined with the technical solutions of the embodiments of the present application in any way, and all belong to the protection scope of the embodiments of the present application. The embodiments of the present application include at least part of the following contents.

[0042] Currently, with the pursuit of rate, delay, high mobility, energy efficiency, and the diversity and complexity of future life services, the 3GPP (3rd Generation Partnership Project, Third Generation Partnership Project) international standard organization has begun to develop 5G. The main application scenarios of 5G are: enhanced mobile broadband (enhanced Mobile Broadband, eMBB), ultra-reliable and low-latency communication (Ultra Reliable and Low Latency Communications, URLLC), and massive machine type communication (massive Machine Type Communications, mMTC).

[0043] NR can also be deployed independently, in order to reduce air interface signaling and quickly recover wireless connection in 5G network environment, a new RRC (Radio Resource Control, Radio Resource Control) state is defined for the purpose of quickly recovering data services, that is, RRC_INACTIVE state (inactive state). This state is different from RRC_IDLE state (idle state) and RRC_CONNECTED state (connected state).

[0044] RRC_IDLE state: mobility is based on UE-based cell selection / reselection, paging is initiated by CN (Core Network), and paging area is configured by CN. There is no UE AS (Access Stratum) context on the base station side, nor is there an RRC connection.

[0045] RRC_CONNECTED state: there is an RRC connection, and there is a UE AS context between the base station and the UE. The network side knows the location of the UE is specific to the cell level. Mobility is network-controlled mobility. Unicast data can be transmitted between the UE and the base station.

[0046] RRC_INACTIVE state: mobility is based on UE-based cell selection / reselection, there is a connection between CN and NR, UE AS context exists on a certain base station, paging is triggered by RAN (Radio Access Network), RAN-based paging area is managed by RAN, and the network side knows the location of the UE is based on the paging area level of the RAN.

[0047] 1. 5G NR paging mechanism

[0048] The main function of paging is to page the UE through the paging message when the UE is in the above-mentioned RRC_IDLE state or RRC_INACTIVE state, or to notify the UE of system message changes or earthquake tsunami / public warning information through short messages. The above-mentioned paging is also applicable to all RRC states of the UE, including the connected state RRC_CONNECTED.

[0049] Paging includes PDCCH (Physical Downlink Control Channel) scrambled by P-RNTI (Paging-Radio Network Temporary Identifier) and PDSCH (Physical Downlink Shared Channel) scheduled by the PDCCH. Paging message is transmitted in PDSCH, and short message can be 8 bits (bits) transmitted in PDCCH.

[0050] For the UE in RRC_IDLE state or RRC_INACTIVE state, since there is no other data communication between the UE and the network device, in order to save the power of the terminal device, the UE can discontinuously monitor the paging channel, that is, the paging DRX (Discontinuous Reception) mechanism is adopted. Under the paging DRX mechanism, the UE only needs to monitor the paging during a PO (Paging Occasion) in each DRX cycle. The PO is composed of multiple PDCCH monitoring occasions on the paging search space, and one PO contains X PDCCH monitoring occasions, X is equal to the actual number of SSB (Synchronization Signal Block) broadcast in the MIB (Master Information Block). In addition, there is a concept of PF (Paging Frame), which refers to a radio frame (which can be fixed at 10 milliseconds), which can contain multiple POs or the starting position of multiple POs.

[0051] The paging DRX cycle is determined by the common cycle in the system broadcast and the dedicated cycle configured in the high layer signaling, and the UE takes the minimum cycle of the two as the cycle of the paging cycle. The high layer signaling can be NAS (Non Access Stratum) signaling. From the perspective of the network device, one paging DRX cycle can have multiple POs, and the position of the UE monitoring the PO is related to the ID (Identifier) of the UE. Specifically, the determination method of the PF and the PO of a certain UE in a paging DRX is as follows:

[0052] The SFN (System Frame Number) number of a PF is determined by the following formula:

[0053] (SFN + PF_offset) mod T = (T div N) * (UE_ID mod N)

[0054] The number Index(i_s) of a PO within a PF is determined by the following formula:

[0055] i_s = floor(UE_ID / N) mod Ns

[0056] The above formula involves the following explanations of parameters:

[0057] T: DRX cycle of paging received by the UE. The network device broadcasts a default DRX cycle, and if the RRC / high layer configures a UE-specific DRX cycle for the UE, the minimum of the network device broadcast DRX cycle and the RRC / high layer configured UE-specific DRX cycle is taken as the DRX cycle of the UE. If the RRC / high layer does not configure a UE-specific DRX cycle for the UE, the network device broadcast DRX cycle is taken as the DRX cycle of the UE.

[0058] N: The number of PFs contained in a T.

[0059] Ns: The number of POs contained in a PF.

[0060] PF_offset: A time domain offset for determining a PF.

[0061] UE_ID: Represents the UE ID, which can be determined based on formula 5G-S-TMSI mod 1024, wherein 5G-S-TMSI refers to 5G-Serving-Temporary Mobile Subscriber Identity (5G serving temporary mobile subscriber identity).

[0062] After the UE calculates the PF, the index of the PO, and the number of PDCCH monitoring occasions in the PO based on the above formula, the starting position of the first PDCCH monitoring occasion of the PO can be determined by the relevant configuration parameters, and the starting position is configured by high layer signaling. The UE determines the PO and blindly detects the paging message according to the determined PO.

[0063] 2. System message update cycle

[0064] In LTE and NR systems, the concept of system message update (change) period is used. As shown in FIG. 2, when the network device wants to update the system message, the network device first repeatedly sends the system message update indication in the nth system message update period, and then repeatedly sends the changed system message in the n+1th system message update period, where the system message can be transmitted in the BCCH (Broadcast Control Channel). As shown in FIG. 2, in the system update period n, the UE receives the system change indication, but the system information at this time is still the system message before the change (i.e., the block filled with slashes). In the system update period n+1, the network device starts to broadcast the changed system message (i.e., the block filled with dots). The block filled with no dots in FIG. 2 represents the system message that has not changed in this process. The boundary of the system message update period is defined as SFN satisfying SFN mod m = 0.

[0065] where m is the number of SFNs included in one system message update period. m = modificationPeriodCoeff * defaultPagingCycle, where modificationPeriodCoeff and defaultPagingCycle are the system message update period coefficient and the default paging cycle respectively, and both of these two parameters are determined by the network device broadcast.

[0066] In the NR system, the system message update period is applicable to the update of system messages other than SIB6, SIB7, SIB8, and positioning assistance data, where SIB refers to System Information Block. In NR:

[0067] If the systemInfoModification in the short message is 1, it means that the update is performed for other system messages except SIB6 / SIB7 / SIB8, and the UE acquires the updated system message in the next system message update period.

[0068] If the etwsAndCmasIndication in the short message is 1, it means that the network wants to send ETWS (Earthquake and Tsunami Warning System) and / or CMAS (Commercial Mobile Alert System) notifications, and the UE re-reads SIB1 and SIB6 / SIB7 / SIB8 immediately after receiving the short message.

[0069] The stopPagingMonitoring bit is only applicable to the operation of shared spectrum channel access, and is used when nrofPDCCH-MonitoringOccasionPerSSB-InPO exists. If stopPagingMonitoring is valued as 1, it means that the UE can stop monitoring the PDCCH paging occasion in this PO.

[0070] 3. Paging false alarm and PEI (Paging Early Indication)

[0071] Paging false alarm means paging false alarm. As can be seen from the above determination of PO, the determination of PO is related to UE ID, and is related to the number of PF and PO. When the system UE is large, the network device cannot allocate each UE to a different PO, and there will be a situation where multiple UEs correspond to one PO. If the network device needs to paging a certain UE in this PO, it is possible to cause other UEs without paging message to perform additional blind detection, mainly including blind detection of PDCCH and corresponding PDSCH. For these UEs without paging message, this false paging is paging false alarm.

[0072] 3GPP agrees to further enhance the terminal energy saving project. One of the goals of the project is to reduce unnecessary UE paging reception (i.e. reduce paging false alarm) by designing an enhanced paging mechanism. To this end, the UE power saving (enhanced energy saving) project introduces the PEI mechanism, and the basic working principle is as follows:

[0073] 1. PEI is based on PDCCH design, and the network device sends PEI before PO, and the UE decides whether to normally monitor paging or can skip paging monitoring in the corresponding PO according to the received PEI indication.

[0074] 2. PEI can be based on UE grouping to indicate wake-up, i.e. further divide the UEs allocated to the same PO into multiple UE groups, and the network device can indicate which UE group the paging message is for, so that other groups of UEs do not need to receive the paging message.

[0075] 4. LP-WUS

[0076] A lower power wake-up signal, i.e. LP-WUS, is also introduced in 3GPP. Compared with PEI mechanism, low power WUS is more energy efficient, it will use a separate lower power receiver, i.e. LR (Ultra-low Power receiver), instead of MR (Main Radio). As shown in sub-figure 1 of FIG. 3, when base station does not send LP-WUS signal, thus the LR of terminal device does not receive LP-WUS. In this way, the main receiver is not started, and the main receiver is in a closed or deep sleep state. As shown in sub-figure 2 of FIG. 3, the base station sends the LP-WUS signal, and for the UE in RRC_IDLE state / RRC_INACTIVE state, after the LR of the terminal device receives the LP-WUS, the main receiver is started to listen to the paging message, so as to achieve the purpose of energy saving. In addition to being used for UEs in RRC_IDLE state / RRC_INACTIVE state, LP-WUS can also be used for UEs in RRC_CONNECTED state.

[0077] Currently, the main functions of paging are as follows: when there is downlink data for a UE, the network device sends paging DCI (Downlink Control Information) on the PO listened by the UE, and carries the paging record (each paging record corresponds to a UE ID) of the UE in the PDSCH (i.e. paging message) indicated by the DCI. When the UE reads its own paging record, it can know that the network device wants to page it, and then initiates a random access process. Another use of paging is to notify system message change. When the base station wants to change the system message, the base station carries a short message in the paging DCI to inform the UE that the system message is to be changed. Since the system message change is for all UEs in the cell, and different UEs listen to paging on different POs, in order to ensure that all UEs can receive the short message, the base station needs to send paging on all POs.

[0078] As mentioned before, the main role of LP-WUS for UE in RRC_IDLE or RRC_INACTIVE state is to wake up the MR of UE to monitor paging. For the information carried in LP-WUS, it has been agreed in the current meeting that at least UE grouping information needs to be carried, i.e. similar to PEI, UEs monitoring paging in the same PO are divided into multiple UE groups, and when the base station needs to page at least one UE, it indicates which or which group of UEs needs to wake up the MR to monitor paging through LP-WUS. In addition, it is mentioned that short message information needs to be carried in LP-WUS, so if the UE receives LP-WUS indicating only system message change without indicating the UE corresponding to the group to wake up the MR to monitor paging, the UE can skip paging reception and directly read the updated system message after waking up the MR.

[0079] For how the base station sends LP-WUS to indicate paging some UEs and system message change, the most intuitive way can reuse the current paging sending mechanism, i.e. the LP-WUS sent by the base station in the same LP-WUS monitoring occasion can indicate both short message information and wake up some or some group of UEs information, so that the UE can determine whether to monitor paging or read the updated system message after receiving the LP-WUS.

[0080] At this time, if the current paging load of the cell is low, and the base station needs to change the system message, in order to notify all UEs of the updated system message, the base station needs to send LP-WUS in all LP-WUS sending occasions, which will consume a lot of system resources and is not conducive to network energy saving.

[0081] Please refer to FIG. 4, which shows a flowchart of a wireless communication method provided by an embodiment of the present application. The method can be applied in the network architecture shown in FIG. 1. As shown in FIG. 4, the method can include the following step 410.

[0082] Step 410, the network device sends configuration information, the configuration information is used for configuring monitoring occasions of at least two types of LP-WUS, wherein different types of LP-WUS have different functions, and different types of LP-WUS are configured different monitoring occasions.

[0083] Correspondingly, the first terminal device receives the configuration information sent by the network device.

[0084] LP-WUS refers to a low-power wake-up signal, which can be received based on a lower-power receiver LR instead of a traditional MR. In this way, the terminal device can only turn on the MR when it is actually needed (such as receiving a paging message, reading a system message, an alarm notification, etc.), thereby reducing power consumption and facilitating energy saving of the terminal device.

[0085] The listening occasion refers to a predetermined time window for the terminal device in network communication, in which the terminal device listens to the LP-WUS signal sent by the network device. Different types of LP-WUS are configured with different listening occasions, which means that the network device specifies different time windows for the terminal device, so that the terminal device can listen to different types of LP-WUS signals in these time windows.

[0086] In some embodiments, at least two types of LP-WUS include: a first type of LP-WUS and a second type of LP-WUS; the first type of LP-WUS is used to wake up at least one terminal group to turn on the MR to listen to the paging message, each terminal group including at least one terminal device; the second type of LP-WUS is used to transmit a short message, the short message being used to indicate at least one of the following: a system message change, a PWS (Public Warning System) notification.

[0087] The MR has relatively high power consumption and sensitivity, and can effectively receive and decode complex signals to ensure the stability and reliability of communication. The paging message is used to notify the terminal device of new information or signals that need to be responded to, and is usually used to wake up the terminal device in a wireless network, so that the terminal device can enter a higher power consumption state to process subsequent data communication.

[0088] A short message refers to a wireless communication message used to convey brief, specific information, typically with a small data volume, for sending brief instructions or notifications so that the terminal device can quickly respond or take corresponding actions. System message change refers to the update of system state or configuration occurring in the wireless network. The purpose of system message change is to ensure the stable operation and coordination of the system, and to inform the terminal device to make corresponding configuration update or state adjustment. System message change can include at least one of the following: network configuration update, device parameter update, service state change, security policy update, resource management adjustment. Among them, network configuration update can include configuration change of base station, network topology adjustment, modification of frequency allocation, etc. Device parameter update can include operation mode change of terminal device, update of communication protocol, upgrade of software version, etc. Service state change can include notification of enabling or disabling of certain services, adjustment of service quality, change of network load, etc. Security policy update can include adjustment of security settings, change of encryption standard, update of access control policy, etc. Resource management adjustment can include change of bandwidth allocation, update of priority policy, reallocation of network resources, etc.

[0089] PWS notification refers to the emergency information or alert sent by the public warning system, used to quickly convey important public safety information to users in emergency situations, such as early warning of natural disasters, major accidents or other emergency events. PWS notification usually has high priority and will produce significant alarm prompts on the terminal device to ensure that users can respond to emergency situations in a timely manner.

[0090] In the above step 410, different types of LP-WUS are configured with different monitoring occasions, i.e. the LP-WUS sent by the network device on one LP-WUS monitoring occasion is only used to indicate a type of LP-WUS. In this way, when the network device wants to send a type of LP-WUS, it can be sent on the monitoring occasion of that type of LP-WUS, without the need to send LP-WUS on all LP-WUS monitoring occasions, thereby effectively saving LP-WUS resource overhead and facilitating network device energy saving.

[0091] In some embodiments, the first type of LP-WUS and the second type of LP-WUS are configured with different monitoring occasions. When the network device wants to send the first type of LP-WUS, it can be sent on the monitoring occasion of the first type of LP-WUS, and when the network device wants to send the second type of LP-WUS, it can be sent on the monitoring occasion of the second type of LP-WUS, thereby effectively saving LP-WUS resource overhead.

[0092] To sum up, the technical scheme provided by the embodiments of the present application configures different monitoring occasions for different types (different functions) of LP-WUS, and when the network device wants to send a certain type of LP-WUS, the network device only needs to send the LP-WUS in the monitoring occasion of the type of LP-WUS, thereby effectively saving the LP-WUS resource overhead and facilitating energy saving of the network device.

[0093] The first type of LP-WUS and the second type of LP-WUS are introduced below.

[0094] In some embodiments, the monitoring occasions of the first type of LP-WUS have a corresponding relationship with the POs.

[0095] The PO refers to a time point at which the network device sends a paging PDCCH (i.e., a PDCCH scrambled by a P-RNTI). When the network device wants to page at least one terminal device, the network device sends the paging PDCCH, which schedules the terminal device to receive a specified paging PDSCH, which is used to transmit a paging message. The monitoring occasion of the terminal device for monitoring the paging PDCCH corresponds to the PO at which the network device sends the paging PDCCH. That is, the monitoring occasion of the terminal device needs to be synchronized with the PO of the network device to ensure that the terminal device can receive the paging PDCCH at the correct time.

[0096] In some embodiments, one monitoring occasion of the first type of LP-WUS corresponds to a plurality of consecutive POs. In this configuration, one LP-WUS is used to indicate whether the terminal devices on the plurality of POs wake up the MR to monitor the paging message on the corresponding POs. A terminal device wakes up the MR according to the indication of the LP-WUS and monitors the paging message on the corresponding PO. Different terminal devices can monitor the paging message on different POs.

[0097] In some embodiments, a plurality of consecutive monitoring occasions of the first type of LP-WUS correspond to one PO. In this configuration, a plurality of terminal devices can monitor the paging message on the same PO, and the terminal devices that monitor the paging on the same PO can be divided into a plurality of terminal groups. A plurality of LP-WUSs are used to indicate whether the terminal devices of different groups on the PO wake up the MR to monitor the paging message. That is, one LP-WUS can be used to indicate whether the terminal devices of one group wake up the MR to monitor the paging message on the PO. Different LP-WUSs can be used to indicate whether the terminal devices of different groups wake up the MR to monitor the paging message on the PO. When the network device needs to page at least one terminal device, the network device can indicate, through the LP-WUS, which or which groups of terminal devices need to wake up the MR to monitor the paging message.

[0098] In some embodiments, one monitoring occasion of the first type of LP-WUS corresponds to one PO. In this configuration, the monitoring occasion and the PO are in one-to-one correspondence, and different monitoring occasions correspond to different POs. One LP-WUS is used to indicate whether the terminal device wakes up the MR to monitor the paging message on the corresponding PO. One terminal device can monitor the paging message on one PO. Different terminal devices can monitor the paging message on different POs.

[0099] In some embodiments, the monitoring occasions of the first type of LP-WUS and the monitoring occasions of the second type of LP-WUS are both periodically distributed. In some embodiments, the monitoring occasions of the first type of LP-WUS and the monitoring occasions of the second type of LP-WUS are repeated at fixed time intervals, so that the terminal device can perform signal reception at a predetermined time point, improving the monitoring efficiency.

[0100] In some embodiments, the monitoring occasions of the second type of LP-WUS can have no corresponding relationship with the POs.

[0101] In some embodiments, the period of the monitoring occasions of the first type of LP-WUS is the same as the period of the monitoring occasions of the second type of LP-WUS. The period of the monitoring occasions of the first type of LP-WUS is the same as the period of the monitoring occasions of the second type of LP-WUS means that the monitoring occasions of the two types are repeated at the same time interval. Exemplarily, the period of the monitoring occasions can be several milliseconds, several seconds, several minutes, etc., which is not limited in the present application. The above method, when the periods of the monitoring occasions of the first type and the second type of LP-WUS are the same, this consistency helps to simplify scheduling and synchronization, and reduces system complexity.

[0102] In some embodiments, the period of the monitoring occasions of the first type of LP-WUS is different from the period of the monitoring occasions of the second type of LP-WUS. The period of the monitoring occasions of the first type of LP-WUS is different from the period of the monitoring occasions of the second type of LP-WUS means that the monitoring occasions of the two types are repeated at different time intervals. In some embodiments, the period of the monitoring occasions of the first type of LP-WUS can be greater than the period of the monitoring occasions of the second type of LP-WUS. Alternatively, the period of the monitoring occasions of the first type of LP-WUS can be less than the period of the monitoring occasions of the second type of LP-WUS. The present application is not limited in this regard. The above method can finely set the monitoring occasions of different types of LP-WUS according to the needs, and is suitable for complex scenarios with different monitoring needs.

[0103] The specific implementation of indicating system message change and PWS notification is introduced below.

[0104] In some embodiments, the monitoring occasion of the second type of LP-WUS for indicating system message change is different from the monitoring occasion of the second type of LP-WUS for indicating PWS notification. When the network device wants to indicate system message change, the corresponding LP-WUS can be sent on the monitoring occasion of the second type of LP-WUS for indicating system message change. When the network device wants to indicate PWS notification, the corresponding LP-WUS can be sent on the monitoring occasion of the second type of LP-WUS for indicating PWS notification. In this way, the network device can select the appropriate monitoring occasion to send the LP-WUS according to different needs, thereby effectively saving the overhead of LP-WUS resources.

[0105] In some embodiments, the monitoring occasion of the second type of LP-WUS for indicating system message change and the monitoring occasion of the second type of LP-WUS for indicating PWS notification are both periodically distributed. In some embodiments, the monitoring occasion of the second type of LP-WUS for indicating system message change and the monitoring occasion of the second type of LP-WUS for indicating PWS notification both occur repeatedly at fixed time intervals, so that the terminal device can perform signal reception at a predetermined time point, thereby improving the monitoring efficiency.

[0106] In some embodiments, the period of the monitoring occasion of the second type of LP-WUS for indicating system message change is the same as the period of the monitoring occasion of the second type of LP-WUS for indicating PWS notification. The period of the monitoring occasion of the second type of LP-WUS for indicating system message change is the same as the period of the monitoring occasion of the second type of LP-WUS for indicating PWS notification means that both monitoring occasions occur repeatedly at the same time interval. Exemplarily, the period of the monitoring occasion can be several milliseconds, several seconds, several minutes, etc., which is not limited in the present application. The above method, when the monitoring occasion period for indicating system message change and the monitoring occasion period for indicating PWS notification are the same, such consistency helps to simplify scheduling and synchronization, and reduces system complexity.

[0107] In some embodiments, the period of the monitoring occasion of the second type of LP-WUS for indicating system message change is different from the period of the monitoring occasion of the second type of LP-WUS for indicating PWS notification. The period of the monitoring occasion of the second type of LP-WUS for indicating system message change is different from the period of the monitoring occasion of the second type of LP-WUS for indicating PWS notification means that both monitoring occasions occur repeatedly at different time intervals.

[0108] In some embodiments, the period of the listening occasion of the second type of LP-WUS for indicating system message change can be greater than the period of the listening occasion of the second type of LP-WUS for indicating PWS notification. Illustratively, the listening occasion of the second type of LP-WUS for indicating system message change can be set to a longer period; while the listening occasion of the second type of LP-WUS for indicating PWS notification can be set to a shorter period. The above method can set a longer listening period to reduce the consumption of resources, since system message change is relatively infrequent. While the public warning system is used to issue emergency notifications or alerts, such as natural disasters, public safety events, etc., which may require a quick response. Therefore, a shorter listening period is needed to capture and process these critical warning information in time, to ensure that users can receive the notification in the first time.

[0109] In some embodiments, the listening occasion of the second type of LP-WUS for indicating system message change is located within a period of time before the boundary of the system message change period, and / or the listening occasion of the second type of LP-WUS for indicating PWS notification is periodically distributed.

[0110] The system message change period, also referred to as the system message update period, refers to the time interval in which the network device updates the system message. The length of the system message change period can be determined according to the number of SFNs contained in the period, m, where m = modificationPeriodCoeff * defaultPagingCycle, and modificationPeriodCoeff and defaultPagingCycle are the system message update period coefficient and the default paging cycle respectively. These two parameters can be determined based on network device broadcast.

[0111] The boundary of the system message change period refers to the time when SFN satisfies the following condition: SFN mod m = 0. That is, the boundary of the system message change period is the time every m SFN. Illustratively, if m = 256, then the boundary of the system message change period is the time when SFN is 0, 256, 512, 768, etc. At these boundary times, the network device will start sending new system message change indications or changed system messages to notify terminal devices to perform corresponding updates.

[0112] The time period before the boundary of the system message change cycle can refer to the last system message change cycle of the boundary of the system message change cycle. As shown in FIG. 2, the time period before the boundary of the system message change cycle can refer to the BCCH update cycle n, that is, the n th system message change cycle. The system message change indication is sent in the time period before the boundary of the system message change cycle, so as to ensure that the terminal device can obtain sufficient early warning time before the system message is actually changed. For example, as shown in FIG. 2, when the network device changes the system message, the network device can first send the system message change indication in the time period before the boundary of the system message change cycle, that is, in the n th system message change cycle, and then send the changed system message in the BCCH update cycle n + 1, that is, in the n + 1 th system message change cycle. The above method sends the system message change indication in the n th system message change cycle. This enables the terminal device to know the existence of the change before the system message is actually changed, and to start preparing to receive and process the changed system message. The network device sends the actually changed system message in the n + 1 th system message change cycle. This ensures that the terminal device is fully prepared when the system message update occurs, and can successfully receive and process the changed system message.

[0113] In some embodiments, the monitoring occasion of the second type of LP-WUS for indicating the PWS notification is periodically distributed. The monitoring occasion of the second type of LP-WUS for indicating the PWS notification is periodically distributed means that the monitoring occasion of the second type of LP-WUS for indicating the PWS notification occurs repeatedly at a fixed time interval. This periodic distribution ensures that the monitoring occasion of the LP-WUS is regularly arranged according to a specific period, rather than randomly or irregularly. For example, assuming that the period of the monitoring occasion of the PWS notification is once every 100 milliseconds, the terminal device will monitor the PWS notification at every 100-millisecond time interval, thereby ensuring accurate reception of the PWS notification.

[0114] In some embodiments, the monitoring occasion of the second type of LP-WUS for indicating the system message change and the monitoring occasion of the second type of LP-WUS for indicating the PWS notification have no correspondence with the PO.

[0115] The following describes specific implementation manners of monitoring the LP-WUS when the first terminal device is in an idle state (RRC_IDLE state) or an inactive state (RRC_INACTIVE state), and in a connected state (RRC_CONNECTED state).

[0116] (1) When the first terminal device is in an idle state or an inactive state

[0117] In some embodiments, when the terminal device is in the idle state or the inactive state, the terminal device needs to perform the MR opening operation in both states after listening to the first type of LP-WUS and / or the second type of LP-WUS, to ensure timely reception of paging messages, system messages, and alarm notifications.

[0118] In some embodiments, the first type of LP-WUS is listened to at a listening occasion of the first type of LP-WUS, and the second type of LP-WUS is listened to at a listening occasion of the second type of LP-WUS, when the first terminal device is in the idle state or the inactive state.

[0119] In some embodiments, since the listening occasions of the first type of LP-WUS and the second type of LP-WUS are both periodically distributed, and the periods of the listening occasions of the two types of LP-WUS can be the same or different. Therefore, the terminal device periodically listens to the first type of LP-WUS and the second type of LP-WUS at the listening occasions of the first type of LP-WUS and the second type of LP-WUS, respectively. In some embodiments, the period of the terminal device listening to the first type of LP-WUS and the second type of LP-WUS can be the same or different.

[0120] In some embodiments, if the first terminal device listens to the first type of LP-WUS at the listening occasion of the first type of LP-WUS, and the first type of LP-WUS indicates to wake up the first terminal device or a terminal group to which the first terminal device belongs, it means that the network device requires the first terminal device to recover from the low-power mode (idle state and inactive state) to receive subsequent paging messages.

[0121] In some embodiments, if the first terminal device listens to the first type of LP-WUS at the listening occasion of the first type of LP-WUS, and the first type of LP-WUS indicates to wake up the first terminal device or a terminal group to which the first terminal device belongs, the MR is opened, and the paging message is listened to on the PO corresponding to the listening occasion of the first type of LP-WUS through the MR. Through the main receiver, the terminal device can receive the paging message from the network device on the PO corresponding to the listening occasion of the first type of LP-WUS, in order to respond to the communication needs of the network device.

[0122] In some embodiments, the terminal devices listening to the LP-WUS on the same PO can be divided into multiple terminal groups. In some embodiments, the grouping of terminal devices can also be performed in other ways, such as grouping based on the type, performance, power consumption demand, communication quality, etc. of the terminal device, or dynamically dividing the terminal groups according to the scheduling strategy, service demand, etc. of the network side. The present application does not limit this, and the specific grouping method can be flexibly determined according to the actual application scenario and demand.

[0123] In some embodiments, if the first terminal device monitors the second type of LP-WUS at the monitoring occasion of the second type of LP-WUS, and the second type of LP-WUS indicates a system message change, the first terminal device starts the MR before the next system message update period, or starts the MR immediately, and reads the system message from the next system message update period through the MR.

[0124] The next system message update period refers to the next update period of the update period in which the second type of LP-WUS indicating the system message change is received. For example, as shown in FIG. 2, the terminal device receives the system message change indication in the nth system message change period, and the next update period refers to the n+1th system message change period. Since the updated system message is transmitted in the next system message update period (i.e., the n+1th system message change period), the terminal device can start the MR before the n+1th system message change period, or can start the MR immediately to read the updated system message.

[0125] In some embodiments, if the first terminal device monitors the second type of LP-WUS at the monitoring occasion of the second type of LP-WUS, and the second type of LP-WUS indicates a PWS notification, the first terminal device starts the MR immediately, and reads the SIB associated with the PWS through the MR.

[0126] The SIB associated with the PWS can include SIB16, which is used to broadcast information related to the public warning system, such as emergency notifications and alerts. These information help the terminal device to timely acquire and process emergency messages from the public warning system. Specifically, it can include the trigger condition of the warning, the format and structure of the warning message, the occasion and frequency of broadcasting, etc., to ensure that the terminal device can correctly receive and process the public warning message, so as to ensure the safety of the public and timely response.

[0127] (2) When the first terminal device is in the connected state

[0128] In some embodiments, when the first terminal device is in the connected state, if the first terminal device is in the light sleep state, the first terminal device needs to perform the wake-up MR operation at this time. If the first terminal device is in the normal working state, the wake-up MR operation does not need to be performed.

[0129] In some embodiments, when the first terminal device is in the connected state, the second type of LP-WUS is monitored at the monitoring occasion of the second type of LP-WUS. For related content, please refer to the related description above.

[0130] In some embodiments, if the first terminal device listens to the second type of LP-WUS at the listening occasion of the second type of LP-WUS, and the second type of LP-WUS indicates a system message change, the first terminal device reads the system message from the next system message update period through the MR; or, if the first terminal device listens to the second type of LP-WUS at the listening occasion of the second type of LP-WUS, and the second type of LP-WUS indicates a PWS notification, the first terminal device reads the SIB associated with the PWS through the MR. For related content, please refer to the related description above.
