[0003] This application belongs to the field of communication technology, and specifically relates to a wake-up signal monitoring and processing method, device and terminal. Background Technology
[0004] With the development of communication technology, low-power modes have been introduced into communication systems. In low-power mode, terminals can listen for wake-up signals (WUS). Currently, the conditions for a terminal to voluntarily exit or enter WUS listening only consider the signal quality of the serving cell. Simultaneously, network-side equipment can control the terminal to exit WUS listening via WUS. Therefore, when a terminal's main receiver is incorrectly woken up based on WUS, it needs to re-determine whether the conditions for entering WUS listening are met based on the signal quality of the serving cell before it can enter low-power mode and perform WUS listening. Thus, this technology suffers from the problem of the terminal's main receiver being incorrectly woken up, leading to higher terminal power consumption. Summary of the Invention

[0007] If a wake-up signal is detected and the terminal's main receiver is woken up, the terminal determines whether the main receiver has been mistakenly woken up.
[0008] If it is determined that the main receiver has been falsely woken up, the terminal listens for the wake-up signal;
[0009] The wake-up signal is used to instruct the terminal to listen for paging.
[0010] Secondly, a wake-up signal monitoring and processing device is provided, comprising:
[0011] The processing module is used to determine whether the main receiver has been mistakenly woken up when a wake-up signal is detected and the main receiver of the terminal is woken up.
[0012] The receiving module is used to allow the terminal to listen for wake-up signals when it is determined that the main receiver has been falsely woken up.
[0013] The wake-up signal is used to instruct the terminal to listen for paging.

[0016] Fifthly, a terminal is provided, including a processor and a communication interface, wherein the processor is used to determine whether the main receiver has been mistakenly woken up when a wake-up signal is detected and the main receiver of the terminal is woken up.
[0017] The communication interface is used for the terminal to listen for wake-up signals when it is determined that the main receiver has been mistakenly woken up;
[0018] The wake-up signal is used to instruct the terminal to listen for paging.
[0019] In a sixth aspect, a readable storage medium is provided, on which a program or instructions are stored, which, when executed by a processor, implement the steps of the method described in the first aspect.
[0020] In a seventh aspect, a chip is provided, the chip including a processor and a communication interface, the communication interface being coupled to the processor, the processor being used to run programs or instructions to implement the method as described in the first aspect.

[0022] In this embodiment, when a wake-up signal is detected and the terminal's main receiver is awakened, the terminal determines whether the main receiver has been falsely awakened. If the main receiver is falsely awakened, the terminal listens for a wake-up signal, wherein the wake-up signal is used to instruct the terminal to listen for paging. Thus, when the main receiver is falsely awakened, the terminal can return to the low-power mode to listen for the wake-up signal, thereby avoiding invalid paging listening and reducing the wake-up time of the main receiver. Therefore, this embodiment reduces the terminal's power consumption. Attached Figure Description

[0032] For ease of understanding, the following describes some aspects of the embodiments of this application:
[0033] 1. Low power wake-up receiver (LP WUR).
[0034] The basic working principle of LP WUR is as follows: the receiver consists of a first module and a second module. The first module is the main communication module, used to receive and transmit communication data from the transmitter. The second module is a low-power module, used to receive the low-power wake-up signal (LP-WUS) and the low-power synchronization signal (LP-SS) sent by the transmitter. The LP-WUS wake-up signal is used to wake up the receiver's main communication module, and the LP-SS provides time reference information and other information for receiving the LP-WUS wake-up signal. For example, it is used for radio resource management (RRM) measurements of the serving cell, and can also provide wake-up link management, such as determining whether to activate or deactivate LP-WUR based on measurement results, or to shut down the main receiver (MR). The first module remains in a powered-off state when not woken up by the second module, and does not transmit or receive data. When downlink data arrives, the second module detects the wake-up signal sent by the transmitter, and if this wake-up signal contains information about the terminal, the second module triggers the first module to switch from the powered-off state to the powered-on state to receive and transmit data. The second module can be turned on continuously or intermittently. When the second module is turned on, it can receive low-power wake-up signals and low-power synchronization signals.
[0035] II. Low-power wake-up signal.
[0036] In this embodiment, WUS can be a low-power wake-up signal (Low Power WUS, LP-WUS).
[0037] To reduce receiving activity in standby mode and effectively shut down the radio frequency (RF) and modem modules, thereby significantly reducing power consumption during communication reception, this can be achieved by introducing the aforementioned low-power receiver into the terminal's receiver module. In one embodiment, this near-zero power receiver does not require complex RF module signal detection (such as amplification, filtering, quantization, etc.) or modem signal processing; it relies solely on passive matched filtering and low-power signal processing.
[0038] In one embodiment, the low-power wake-up signal is typically a simple on-off keying (OOK) signal, allowing the receiver to detect the wake-up notification through simple energy detection and subsequent sequence detection and identification. In another embodiment, the low-power wake-up signal can be a Frequency Shift Keying (FSK) signal, an Orthogonal Frequency Division Multiplexing (OFDM) signal, or a hybrid signal of OFDM with OOK or FSK. Furthermore, while the terminal activates the low-power receiver to receive the wake-up signal, the main receiver module can maintain a low power consumption level, thereby achieving power savings through receiving the wake-up signal.
[0039] The reception of low-power wake-up signals can be applied to terminals in Radio Resource Control (RRC) idle or RRC inactive states, as well as terminals in RRC connected states, thereby achieving terminal energy saving.
[0040] III. Listen for the entry and exit conditions of the low-power wake-up signal.
[0041] When a terminal is configured with a Low Power Receiver (LP-WUR), it can only begin listening for LP-WUS in the Radio Resource Control (RRC) idle (RRC_IDLE) or RRC inactive (RRC_INACTIVE) state if the entry condition for listening for the Low Power Wake-up Signal (LP-WUS) is met. When the terminal is listening for LP-WUS, it does not need to periodically listen for paging during paging events; it will only activate its main receiver to listen for paging after LP-WUS is detected. Currently, the entry condition for LP-WUS listening in the Third Generation Partnership Projects (3GPP) is that the quality of the serving cell measured by MR is higher than a threshold.
[0042] When a terminal is listening to LP-WUS, if the LP-WUS listening exit condition is met, the terminal stops listening to LP-WUS and enables MR to periodically listen for paging during paging opportunities. Currently, the 3GPP LP-WUS listening exit condition is that the quality of the serving cell measured by LR is below a threshold.
[0043] IV. Paging and terminal false alarms.
[0044] Paging mechanisms in related technologies: Network-side devices can send paging messages to terminals in idle, inactive, and connected states. The paging process can be used to notify a terminal to receive a paging request and / or to notify the system of information updates, as well as to notify the terminal to receive information from the Earthquake and Tsunami Warning System (ETWS) and Commercial Mobile Alert Service (CMAS).
[0045] For each terminal, a paging occasion (PO) needs to be detected within a discontinuous reception (DRX) cycle. The terminal calculates its corresponding PO based on its User Equipment Identifier (UE_ID), the DRX cycle, and the paging configuration information from the network-side equipment. The terminal listens for the paging Physical Downlink Control Channel (PDCCH) at its corresponding PO, which is the Downlink Control Information (DCI) format 1_0 addressed with the P-RNTI. The paging PDCCH contains a short message indicator, the short message, and the time-frequency resource location of the PDSCH carrying the paging message. If the paging PDCCH indicates scheduling information, the User Equipment Identifier (UE) detects the corresponding Physical Downlink Shared Channel (PDSCH) according to the paging PDCCH indication and receives the paging message. If the paging PDCCH only indicates a short message, such as a System Information (SI) change or a Public Warning System (PWS) notification, the terminal does not need to continue receiving paging messages. The paging message (data on the PDSCH) received by the terminal contains a list of the paged terminals' identities. The terminal needs to match its own identity information with the identities carried in the paging message. If it finds its own identity information, it considers itself to be paged; otherwise, it is a false alarm.
[0046] In DCI format 1_0, 2 bits are used to represent the Short Message Indicator, and the specific meaning of the indication is shown in Table 1.
[0047] Table 1:
[0048] In DCI format 1_0, 8 bits are used to represent Short Message, and the specific meanings are shown in Table 2.
[0049] Table 2:
[0050] Optionally, it's possible that 1024 terminals are listening for the same paging message. When the network-side device wants to page one of these terminals, the other 1023 terminals listening for the same PO will mistakenly believe it's a pager for themselves. They might then try to receive a paging message, only able to determine if the paging message is for them based on the UE identification information carried within it. This results in 1023 terminals being incorrectly woken up to listen for paging messages, leading to a waste of energy.
[0051] After the introduction of LP-WUS, the number of terminals listening to the same LP-WUS will be relatively large. Therefore, when LP-WUS is used to wake up one of the terminals, the terminals listening to the same LP-WUS will also wake up to listen to the PO, resulting in a waste of energy.
[0052] To save power, the LP-WUS grouping scheme has been agreed upon. This scheme divides all terminals listening to a PO into N groups, using LP-WUS to carry group identifiers. Only UEs in the corresponding group will listen to the PO and subsequent paging messages. For example, if 1024 terminals are divided into four groups, with each group containing 256 terminals, when a terminal is paged, only 255 terminals in the same group will mistakenly wake up to listen to the PO.
[0053] The wake-up signal monitoring and processing method provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.
[0054] Referring to Figure 2, this application embodiment provides a wake-up signal monitoring and processing method, as shown in Figure 2, the wake-up signal monitoring and processing method includes:
[0055] Step 201: If a wake-up signal is detected and the main receiver of the terminal is woken up, the terminal determines whether the main receiver has been mistakenly woken up.
[0056] Step 202: If it is determined that the main receiver has been mistakenly woken up, the terminal listens for the wake-up signal;
[0057] The wake-up signal is used to instruct the terminal to listen for paging.
[0058] In this embodiment, the terminal can listen for a wake-up signal through its low-power receiver, i.e., when the terminal's main receiver is in standby or sleep mode. When the terminal's main receiver is detected, it can wake up the terminal's main receiver. At this time, the terminal will exit the low-power mode and the terminal's main receiver will listen for paging.
[0059] It should be understood that the terminal's main receiver being woken up can be interpreted as the terminal transitioning from low-power mode to exiting low-power mode, or as the terminal's main receiver transitioning from a state where it is not listening for paging on the PO to a state where it can periodically listen for paging at the corresponding PO location.
[0060] It should be noted that, provided that the terminal's main receiver has not been falsely woken up, the terminal's main receiver will continue to periodically listen to the PO.
[0061] Optionally, when the main receiver of the terminal is woken up, the terminal can determine whether the main receiver has been mistakenly woken up. In this case, the terminal can continue to return to the low-power mode to listen for the wake-up signal, so as to avoid invalid paging and reduce the wake-up time of the main receiver, thereby reducing the power consumption of the terminal.
[0062] In this embodiment, when a wake-up signal is detected and the terminal's main receiver is awakened, the terminal determines whether the main receiver has been falsely awakened. If the main receiver is falsely awakened, the terminal listens for a wake-up signal, wherein the wake-up signal is used to instruct the terminal to listen for paging. Thus, when the main receiver is falsely awakened, the terminal can return to the low-power mode to listen for the wake-up signal, thereby avoiding invalid paging listening and reducing the wake-up time of the main receiver. Therefore, this embodiment reduces the terminal's power consumption.
[0063] Optionally, in some embodiments, the terminal determining whether the main receiver has been falsely woken up includes:
[0064] If the first condition is met, the terminal determines that the main receiver has been mistakenly woken up:
[0065] The first condition includes: after the main receiver is woken up, a paging message is received based on the detected paging PDCCH, and the paging message does not carry the identity information of the terminal.
[0066] It should be understood that, in the embodiments of this application, after the main receiver is woken up, the terminal can detect the paging PDCCH on the PO corresponding to the terminal. The paging PDCCH indicates scheduling information. The terminal continues to receive or detect paging messages based on the detected paging PDCCH. After receiving the paging message, the terminal can determine whether the main receiver of the terminal has been mistakenly woken up based on the paging message. For example, if the paging message does not carry the identity information of the terminal, it can be considered that the main receiver of the terminal has been mistakenly woken up.
[0067] Optionally, since the terminal's identity information is carried in the paging message, it can be confirmed whether the wake-up is a false wake-up. If it is confirmed to be a false wake-up, it can immediately enter or return to the state of listening for the wake-up signal, that is, enter or return to the state of listening for the wake-up signal in low power mode, thereby reducing the terminal's power consumption.
[0068] Optionally, in some embodiments, the first condition further includes at least one of the following:
[0069] The paging PDCCH carries first indication information, which indicates that the paging message scheduled by the paging PDCCH contains the identity information of all the paging terminals.
[0070] The paging message carries second indication information, which indicates that the paging message contains the identity information of all the paging terminals.
[0071] In this embodiment of the application, the aforementioned identity information may include a 5G-S-Temporary Mobile Subscriber Identity (TMSI) or an Inactive Radio Network Temporary Identifier (I-RNTI). Specifically, when the terminal is in the RRC_IDLE state, the identity information can be the 5G-S-TMSI; when the terminal is in the RRC_INACTIVE state, the identity information can be the I-RNTI.
[0072] Since the paging PDCCH or paging message indicates whether the paging message contains the identity information of all the paging terminals, the terminals can more accurately determine whether their master receiver has been falsely woken up. Therefore, the embodiments of this application improve the accuracy of false wake-up judgment and avoid paging failure due to terminal judgment errors.
[0073] Optionally, in some embodiments, when it is determined that the main receiver has been falsely woken up, the terminal listening for the wake-up signal includes:
[0074] When the conditions for listening to the wake-up signal are met, the terminal listens for the wake-up signal;
[0075] The wake-up signal monitoring conditions include determining that the main receiver has been mistakenly woken up.
[0076] In this embodiment, it can be determined whether the terminal is listening for a wake-up signal based on whether the wake-up signal listening conditions are met. In some embodiments, the wake-up signal listening conditions may further include the signal quality requirements of the serving cell. For example, if it is determined that the main receiver has been mistakenly woken up and the signal quality of the serving cell is greater than a preset threshold, it is determined that the wake-up signal listening conditions are met. This ensures that the terminal can receive the wake-up signal normally after entering low-power mode, and the terminal's main receiver can be woken up normally, thereby improving the reliability of communication.
[0077] Optionally, the terminal listening wake-up signal can be understood as: the terminal's main receiver is turned off or nearly turned off, and the terminal's main receiver no longer periodically listens to PO.
[0078] Optionally, in some embodiments, the method further includes:
[0079] If the second condition is met, the terminal believes that it cannot determine whether the main receiver has been falsely woken up;
[0080] The second condition includes any one of the following:
[0081] After the main receiver is woken up, no paging PDCCH is detected on the paging time PO corresponding to the terminal;
[0082] After the main receiver is woken up, no paging message is received based on the detected paging PDCCH, and the paging PDCCH indicates that there is scheduling information;
[0083] After the main receiver is woken up, a paging message is received based on the detected paging PDCCH. The paging message does not carry the identity information of the terminal and meets the third condition.
[0084] The third condition includes at least one of the following:
[0085] The paging PDCCH carries third indication information, which is used to indicate that the paging message scheduled by the paging PDCCH does not contain the identity information of all the paging terminals.
[0086] The paging message carries a fourth indication information, which indicates that the paging message does not contain the identity information of all the paging terminals.
[0087] In this embodiment of the application, if the terminal believes that it cannot determine whether the main receiver has been mistakenly woken up, the terminal will not return to the low power mode to listen for the wake-up signal, and the main receiver of the terminal will continue to periodically listen for the PO.
[0088] It should be noted that if no paging PDCCH is detected on the paging time PO corresponding to the terminal, the terminal assumes that the network-side device will send a paging PDCCH on a subsequent PO, or the terminal has missed listening to the paging PDCCH, so it is impossible to determine whether the current master receiver has been mistakenly woken up.
[0089] When a paging PDCCH is detected on the paging time PO corresponding to the terminal, and the paging PDCCH indicates that there is scheduling information, the terminal believes that the network-side device will send a paging message in the future. However, the terminal does not detect the paging message, so the terminal will think that it has missed listening to the paging message scheduled by the paging PDCCH, and therefore cannot determine whether the current master receiver has been mistakenly woken up.
[0090] After the main receiver is woken up, it receives a paging message based on the detected paging PDCCH. If the paging message does not carry the terminal's identity information and the third condition is met, the terminal believes that the network-side device has not completed paging for all terminals and may send a paging PDCCH for scheduling the terminal on a subsequent PO. Therefore, it is impossible to determine whether the current main receiver has been mistakenly woken up.
[0091] Optionally, in some embodiments, when it is determined that the main receiver has been falsely woken up, the terminal listening for the wake-up signal includes:
[0092] If it is determined that the main receiver has been mistakenly woken up within the first time period, the terminal listens for the wake-up signal.
[0093] In this embodiment, the aforementioned first time period can be agreed upon by a protocol or indicated by the network-side device. It should be understood that after the terminal's main receiver is woken up, if it can be determined within the first time period that the main receiver was mistakenly woken up, the terminal can immediately enter or return to the state of listening for the wake-up signal, i.e., enter or return to the low-power mode to listen for the wake-up signal. If it cannot be determined within the first time period whether the main receiver was mistakenly woken up, the terminal may be unable to receive the wake-up signal due to moving to the cell edge or deteriorating communication quality. Therefore, even if it is determined after the first time period that the main receiver was mistakenly woken up, there is no need to enter the state of listening for the wake-up signal, which may result in the terminal being unable to listen for the wake-up signal and thus preventing the terminal's main receiver from being woken up.
[0094] Optionally, in some embodiments, the start time of the first time period includes any of the following:
[0095] The moment when the terminal receives the wake-up signal;
[0096] The main receiver is based on the time when the wake-up signal is activated (ramp-up time);
[0097] The time when the terminal completes synchronization after the main receiver is woken up by the wake-up signal;
[0098] The main receiver is based on the start time of the time unit where the target paging opportunity is located after the wake-up time of the wake-up signal, and the target paging opportunity is the paging opportunity closest to the time when the main receiver is woken up by the wake-up signal.
[0099] In this embodiment of the application, the first time period mentioned above may include N time units, which may include any of the following: paging DRX cycle, frame, subframe, time slot, OFDM symbol, second, millisecond.
[0100] Optionally, in some embodiments, when it is determined that the main receiver has been mistakenly woken up during the first time period, the terminal listening for the wake-up signal includes:
[0101] If it is determined that the main receiver has been mistakenly woken up within the first time period and the fourth condition is met, the terminal listens for the wake-up signal.
[0102] The fourth condition includes at least one of the following:
[0103] The terminal did not transmit any data during the first time period;
[0104] The terminal is in a low-mobility state during the first time period;
[0105] The terminal's serving cell quality is higher than a first threshold during the first time period;
[0106] The terminal did not perform cell selection or reselection during the first time period;
[0107] The terminal did not track or register region updates during the first time period.
[0108] Optionally, being in a low-mobility state can be understood as: the change in the signal quality of the serving cell of the terminal is less than a preset threshold within the second time period. The preset threshold and the first threshold can be agreed upon by the protocol or configured by the network-side equipment, and are not further limited here.
[0109] Optionally, in some embodiments, the terminal determines whether to listen for the wake-up signal based on the entry condition of the wake-up signal.
[0110] The conditions for receiving the wake-up signal include at least one of the following:
[0111] The quality of service provided to the community exceeds the second threshold.
[0112] The terminal's moving speed is below the third threshold.
[0113] In this embodiment, if it cannot be determined whether the main receiver has been falsely woken up within the first time period, even if it is determined after the first time period that the main receiver has been falsely woken up, listening for the wake-up signal cannot begin immediately. The entry conditions for listening for the wake-up signal must be met before listening can begin. This avoids the possibility that the terminal might fail to receive the wake-up signal due to moving to the cell edge or deteriorating communication quality. Therefore, this embodiment improves the reliability of terminal communication.
[0114] Optionally, in some embodiments, the second threshold is greater than the first threshold.
[0115] To better understand this application, some examples are provided below.
[0116] Example 1: The paging PDCCH carries target indication information (such as the first indication information and the third indication information mentioned above) to indicate whether the paging message contains the identity information of all the paged terminals.
[0117] Target indication information can be carried in the paging PDCCH or in the paging message. If carried in the paging PDCCH, it is carried by using 1 bit of the short message in the paging PDCCH to indicate the first indication information, for example, bit 5 below is used to indicate the first indication information. If bit 5 of the short message in the paging PDCCH is set to 1, the terminal believes that the current paging message contains the second indication information, that is, it believes that it contains the identity information of all paged UEs; optionally, if bit 5 is not set to 1, the terminal believes that the paging PDCCH contains the third indication information, that is, the terminal believes that the current paging message does not contain the identity information of all paged UEs. The specific meaning of the short message is shown in Table 3.
[0118] Table 3:
[0119] Alternatively, it can be carried by using 1 bit of the short message in the paging PDCCH to indicate the third indication information, for example, bit 5 below is used for the third indication information. If bit 5 of the short message in the paging PDCCH is set to 1, the UE believes that the current paging message contains the fourth indication information, that is, it believes that it does not contain the identity information of all paged UEs; optionally, if bit 5 is not set to 1, the UE believes that the paging PDCCH contains the first indication information, that is, the UE believes that the current paging message already contains the identity information of all paged UEs. The specific meaning of the short message is shown in Table 4.
[0120] Example 2: The paging message carries target indication information (such as the second and fourth indication information mentioned above) to indicate whether the paging message contains the identity information of all the paged terminals.
[0121] Optionally, one IE in the paging message can be used to indicate the second indication information. For example, if pagingindication is set to true, the UE believes that the identity information of all paged UEs has been included; if pagingindication is not included, the UE believes that the identity information of all paged UEs has not been included.
[0122] Optionally, one IE in the paging message is used to indicate the fourth indication information. For example, if pagingindication is set to true, the UE believes that the identity information of all paged UEs is not included; if pagingindication is not included, the UE believes that the identity information of all paged UEs is included.
[0123] Optionally, one IE in the paging message is used to indicate the second and fourth indication information. For example, if pagingindication is set to true, the UE believes that the identity information of all paged UEs has been included; if pagingindication is set to false, the UE believes that the identity information of all paged UEs has not been included. Alternatively, if pagingindication is set to false, the UE believes that the identity information of all paged UEs has been included; if pagingindication is set to true, the UE believes that the identity information of all paged UEs has not been included.
