[0055] Before introducing the technical solution of this application, some background technical knowledge involved in this application is first introduced and explained. The following related technologies can be combined with the technical solution of the embodiment of this application as optional solutions, and they all fall within the scope of protection of the embodiment of this application. The embodiment of this application includes at least part of the following contents:

[0056] 1) Energy-saving design of terminal equipment

[0057] In order to reduce the power consumption of terminal devices, both LTE and NR systems have a discontinuous reception (DRX) mechanism, which allows terminal devices to not have to keep the receiver turned on when there is no data to receive, but instead enter a discontinuous reception state, thereby achieving the purpose of saving power. In the evolution of NR technology, higher requirements are placed on power saving of terminal equipment (User Equipment, UE). For example, with the existing DRX mechanism, during each wake-up period (on duration), the UE needs to continuously detect the Physical Downlink Control Channel (PDCCH) to determine whether the base station schedules data transmission to itself. However, for most UEs, there may be no need to receive data transmission for a long time, but it is still necessary to maintain regular wake-up to monitor possible downlink transmissions. For this type of UE, there is room for further optimization of terminal device power saving.

[0058] In the R16 standard, an energy-saving signal is introduced to achieve further energy saving of terminal devices in the Radio Resource Control (RRC) connected (CONNECTED) state. The energy-saving signal is used in combination with the DRX mechanism, and the terminal device receives an indication of the energy-saving signal before the on duration. When the terminal device has data to transmit in the upcoming on duration, the network "wakes up" the terminal device through the energy-saving signal to monitor the PDCCH during the upcoming on duration; otherwise, the network instructs the terminal device to continue "sleep" through the energy-saving signal, and the terminal device does not need to monitor the PDCCH during the upcoming on duration. Compared with the existing DRX mechanism, when the terminal device has no data to transmit, the terminal device can omit the monitoring of the PDCCH during the on duration, thereby achieving energy saving.

[0059] In the R17 standard, a terminal equipment energy-saving enhancement project was established to further standardize the energy saving of terminal equipment in the RRC idle (IDLE) state and the RRC inactive (INACTIVE) state. The power consumption of terminal equipment in the RRC IDLE and RRC INACTIVE states mainly comes from periodic discontinuous reception of paging, which includes time-frequency synchronization recovery and automatic gain control (AGC) before the paging opportunity arrives, as well as the power consumption of detecting the paging PDCCH during the paging opportunity. In order to reduce power consumption during the paging reception process, the R17 standard introduced an energy-saving signal for paging reception, called Paging Early Indication (PEI), which is used to indicate whether the terminal device needs to receive paging at the paging opportunity before the paging opportunity arrives.

[0060] 2) PEI design in R17

[0061] ①PEI Occasion (PEI-O)

[0062] PEI-O is a collection of multiple PDCCH monitoring opportunities. Specifically:

[0063] 1. When the number of PDCCH monitoring opportunities corresponding to a synchronization signal block (SSB) within a paging opportunity (nrofPDCCH-MonitoringOccasionPerSSB-InPO) is not configured, the monitoring opportunity of PEI is a set of S consecutive PDCCH monitoring opportunities.

[0064] Where S is the number of SSBs actually transmitted, determined by the time-domain position (ssb-PositionsInBurst) of the SSBs transmitted in the half-frame with the synchronization signal (SS) / PBCH block in SIB1.

[0065] In the PEI monitoring occasion, the Quasi-Colocation (QCL) of the Kth PEI PDCCH monitoring occasion is the same as the Kth PDCCH monitoring occasion of paging in the paging occasion (PO) (the reference of QCL is SSB).

[0066] 2. In the unlicensed spectrum, the PEI monitoring opportunity is a set of (S*X) consecutive PDCCH monitoring opportunities.

[0067] Where S is the number of actual transmitted SSBs determined by ssb-PositionsInBurst in SIB1; if nrofPDCCH-MonitoringOccasionPerSSB-InPO is configured, X takes the configured value, otherwise X=1;

[0068] The (x*S+K)th PDCCH monitoring opportunity in the PEI monitoring opportunity corresponds to the Kth SSB transmitted, where x=0, 1,…, X-1, K=1, 2…, S; if X>1, when the terminal device detects a PEI in the PEI monitoring opportunity, the terminal device does not need to continue to monitor the subsequent monitoring opportunities associated with the PEI monitoring opportunity.

[0069] ② Mapping of PEI and PO

[0070] The network can configure multiple POs for each paging frame (PF). If each PEI corresponds to a PO, there will be a large number of independent PEIs, which will increase the PEI overhead. On the other hand, the PEIs corresponding to these POs may overlap in the time domain. In Rel-15 / 16, a wake-up signal (WUS) can be associated with one or multiple POs. When designing PEIs, in order to reduce PEI overhead and avoid PEI overlap, a mapping mechanism similar to WUS was finally determined, that is, one PEI can be associated with one or multiple POs. The specific design is as follows:

[0071] Supports one PEI associated with high-level configuration parameters (POnumPerPEI) PO:

[0072] 1. The POnumPerPEI POs associated with a PEI can be in one or more PFs. The maximum number of PFs associated with a PEI is 2.

[0073] 2.POnumPerPEI is N*N S The factor of N is the number of paging frames in a paging cycle, N S POnumPerPEI is the number of POs in a paging frame. POnumPerPEI can be configured through the System Information Block (SIB) and has a value range of {1, 2, 4, 8}.

[0074] ③Determination of PEI-O position

[0075] Figure 2 shows a schematic diagram of PEI-O position determination according to an exemplary embodiment of the present application. The terminal device determines the position of the PO corresponding to the PEI-O based on the reference point and the offset value (from the reference point to the first PDCCH monitoring opportunity of the PEI-O).

[0076] 1. First determine the reference frame and use the starting point of the reference frame as the reference point.

[0077] Based on the first PF among all PFs associated with PEI (when a PEI is associated with multiple POs, the associated POs may be located in different PFs), the reference frame is determined by a frame-level offset value;

[0078] The frame-level offset value from the first PF among all PFs associated with the PEI to the reference frame is configured through the SIB.

[0079] 2. Based on the reference point and symbol-level offset value, determine the position of the first PDCCH monitoring opportunity in PEI-O.

[0080] The symbol-level offset from the reference point to the first PDCCH monitoring opportunity in PEI-O can be configured through the SIB, and the specific offset value is provided by the offset (expressed in symbols) from the start of the reference frame of PEI-O to the start of the first PDCCH monitoring opportunity of PEI-O.

[0081] 3) LP-WUS / WUR in 3GPP Release 18

[0082] The 3GPP R18 research project considers further energy-saving processing for terminal devices. The study introduces a low-power wake-up receiver (LP-WUR) and designs a low-power wake-up signal (LP-WUS). The LP-WUR monitors the LP-WUS signal. When the LP-WUR receives the wake-up signal from the network device, it wakes up the main receiver. Specifically, when the LP-WUR is used to monitor the wake-up signal, the main receiver (MR) can be in an ultra-low power (Ultra Deep Sleep) state, thereby achieving overall energy saving for the terminal device.

[0083] ① LP-WUR clock considerations (as of RAN1#113 meeting)

[0084] When studying LP-WUS / WUR, the RAN1 working group reached a preliminary consensus on the accuracy of the LP-WUR oscillator, considering the following four options:

[0085] Option 1: The maximum frequency error of the oscillator is 200ppm, and the frequency drift of the oscillator is 0.1ppm / s;

[0086] Option 2: The maximum frequency error of the oscillator is 50ppm, and the frequency drift of the oscillator is 0.1ppm / s;

[0087] Option 3: The maximum frequency error of the oscillator is 10ppm, and the frequency drift of the oscillator is 0.05ppm / s;

[0088] Option 4: The maximum oscillator frequency error is 5ppm, and the oscillator frequency drift is 0.05ppm / s;

[0089] Consider that the maximum frequency error of the LP-WUR's real-time clock (RTC) is 20ppm, and the frequency drift is 0.1ppm / s.

[0090] ②LP-WUR power consumption model (as of RAN1#113 meeting)

[0091] As shown in Table 1, the RAN1 Working Group reached the following conclusions on the LP-WUR power consumption model (for research and evaluation purposes only; the final LP-WUR design may have multiple types or just one):

[0092] Table 1

[0093] 1. Whether to classify or subclassify requires further study;

[0094] 2. The mapping of power consumption values ​​to LP-WUR receiver structures or LP-WUR operating modes requires further study.

[0095] 3. If the power consumption value of LP-WUR in the power on state is 10 / 20 / 30:

[0096] Receivers based on envelope detection cannot be used when monitoring LP-WUS;

[0097] When the noise figure is less than [MR noise figure + 2.5dB], an orthogonal frequency-division multiplexing (OFDM) receiver is used to monitor the LP-WUS.

[0098] 4. If the power consumption value of LP-WUR in the Power on state is 0.2 / 0.5 / 1 / 2 / 4:

[0099] When performing LP-WUS monitoring, consider other noise figures that are greater than [MR Noise figure + 2.5dB];

[0100] 5. If the power consumption value of LP-WUR in the Power Off state is 0.001:

[0101] The oscillators of options 1, 2, 3, and 4 are not applicable and can only maintain the RTC;

[0102] 6. If the power consumption value of LP-WUR in the Power Off state is 0.1:

[0103] The oscillators of options 3 and 4 cannot be used in receivers based on envelope detection.

[0104] ③Measurement Design (as of RAN1#113 meeting)

[0105] As of RAN1#113 meeting, the following consensus was reached on LP-WUR radio resource management (RRM) measurements:

[0106] 1. RAN1 has identified at least the following metrics for further study and evaluation regarding RRM serving cell measurements performed by LP-WUR based on reference signals, including feasibility, complexity, and power consumption:

[0107] Low Power Received Signal Strength Indicator (LP-RSSI) or energy detection: The linear average of the total power received on the RSSI resource;

[0108] Low Power Reference Signal Received Power (LP-RSRP): The linear average of the received power of the reference signal sent by the signal source, or a portion of the signal;

[0109] Low Power Signal to Interference plus Noise Ratio (LP-SINR) = LP-RSRP / (power of interference and noise);

[0110] Low Power Reference Signal Receiving Quality (LP-RSRQ) = [N x] LP-RSRP / LP-RSSI, where N is a factor that accounts for the difference in LP-RSRP and LP-RSSI resource sizes.

[0111] The accuracy of AGC requires at least a 4-bit analog-to-digital converter (ADC).

[0112] The reference signals for measurement can be: SSB, LP-WUS waveform sequence, low power synchronization signal (Low Power Synchronization Signal, LP-SS), etc., where SSB includes primary synchronization signal (Primary Synchronization Signal, PSS), secondary synchronization signal (Secondary Synchronization Signal, SSS), physical broadcast channel (Physical Broadcast Channel, PBCH) and demodulation reference signal (Demodulation Reference Signal, DMRS).

[0113] 2. For Idle / Inactive mode, the study is to offload the RRM measurements of the serving cell to the LP-WUR under certain conditions, and consider the relaxation of the RRM measurements of the serving cell / neighboring cell in the MR:

[0114] Periodic reference signals are used for LP-WUR measurements: SSB (PSS / SSS / PBCH DMRS), LP-WUS waveform sequence, LP-SS, etc.

[0115] MR performs RRM measurements:

[0116] Option 1: If MR considers RRM measurement relaxation, then the relaxed period is adopted;

[0117] Option 2: Perform RRM measurement of MR only when the LP-WUR measurement based on the reference signal meets certain conditions, such as being below a threshold.

[0118] ④ LP-WUS monitoring activation / deactivation design (as of RAN1#113 meeting)

[0119] 1. For the IDLE / INACTIVE state, the RAN1 working group is considering studying the following methods for activating and deactivating LP-WUS monitoring of the UE via LP-WUR:

[0120] Option 1:

[0121] The gNB transmits the traditional paging indication and LP-WUS;

[0122] Activate and / or deactivate the monitoring of the wake-up signal of the LP-WUS according to the UE implementation;

[0123] Activation / deactivation can be performed based on channel conditions, such as whether coverage is sufficient;

[0124] Option 2:

[0125] The gNB transmits the traditional paging indication and LP-WUS;

[0126] Decide to activate and / or deactivate the monitoring of the wake-up signal of the LP-WUS according to pre-configured criteria;

[0127] Activation / deactivation can be performed based on channel conditions, such as whether coverage is sufficient;

[0128] Option 3:

[0129] Activation / deactivation of LP-WUS monitoring is determined based on signaling within the cell.

[0130] 2. For the RRC CONNECTED state, LP-WUS monitoring can be activated / deactivated in at least one of the following ways:

[0131] Through the RRC signaling of the gNB, it can be based on or without UE support;

[0132] Layer 1 / Layer 2 (L1 / L2) LP-WUS activation / deactivation signaling via the gNB, with or without UE support;

[0133] Based on preconfigured criteria, such as timers;

[0134] The monitoring of LP-WUS by the terminal device is known to the gNB.

[0135] In 3GPP Release 18, research on the low-power wake-up signal (LP-WUS) and the low-power wake-up receiver (LP-WUR) was carried out. Currently, this is in the SI phase and no standard has been finalized.

[0136] The wake-up receiver has the characteristics of extremely low cost, extremely low complexity and extremely low power consumption. It mainly receives the wake-up signal through an envelope detection-based method. Therefore, the LP-WUS received by the wake-up receiver is different from the modulation method and waveform of the signal carried by the PDCCH defined in the existing 3GPP R16 and R17 standards. The wake-up signal is mainly an envelope signal modulated by amplitude shift keying (ASK) of the carrier signal. The demodulation of the envelope signal is also mainly based on the energy provided by the wireless radio frequency signal to drive the low-power circuit to complete, so it can be passive. The wake-up receiver can also be powered by the terminal device. Regardless of the power supply method, the receiver greatly reduces power consumption compared to the traditional receiver of the UE. The wake-up receiver can be combined with the UE as an additional module of the UE receiver, or it can be used as a wake-up function module of the UE alone. Figure 3 shows a block diagram of the terminal device receiver system involved in an exemplary embodiment of the present application. The wake-up receiver receives the wake-up signal and can instruct the UE to turn on the main receiver if the UE needs to turn on the receiver. Otherwise, the main receiver of the UE can be in the off state.

[0137] The LP-WUS signal can be used to wake up the MR. Specifically, the UE's LP-WUR monitors the LP-WUS. When it receives an LP-WUS signal sent to the terminal device or to the terminal group to which the terminal device belongs, the LP-WUR wakes up the MR. Generally, the LP-WUR can monitor the LP-WUS continuously or discontinuously using a duty cycle.

[0138] When a network device needs to communicate with a terminal device UE containing LP-WUR, it can first send an LP-WUS signal to wake up the terminal device, turn on the main receiver MR of the terminal device UE, and receive PDCCH and / or PDSCH and other signals sent by the network device through the main receiver MR.

[0139] Considering factors such as the implementation methods and sensitivity differences between LP-WUR and MR, it is difficult to achieve the same coverage effect for LP-WUR and MR. In other words, the coverage range of LP-WUR receiving LP-WUS is often different from the coverage range of MR receiving PDCCH, PDSCH, etc.:

[0140] For legacy UEs that do not have LP-WUR before 3GPP R17, the network device can page the UE through the Paging PDCCH.

[0141] For UEs with LP-WUR introduced in 3GPP R18, the network equipment can wake up the UE's MR through LP-WUS to implement paging of the UE. The UE can be paged through LP-WUS, or after waking up the UE's MR, the UE can be paged through Paging PDCCH.

[0142] FIG4 shows the coverage of LP-WUS and Paging PDCCH signals involved in an exemplary embodiment of the present application. For a terminal device in a cell where the same network device is deployed, it may be located within the LP-WUS coverage area or outside the LP-WUS coverage area.

[0143] When the terminal device UE is within the coverage of LP-WUS, it can monitor LP-WUS through LP-WUR. If it monitors LP-WUS sent to itself or its terminal group, it wakes up the MR to monitor the paging PDCCH or PDSCH. At this time, the network device can wake up the terminal device through LP-WUS.

[0144] When the terminal device UE is outside the coverage of LP-WUS, in this case, the UE cannot wake up the MR through the LP-WUS signal. At this time, the UE needs to use the MR to monitor whether there is a paging signal sent to it by a network device.

[0145] For a network device, when it is necessary to initiate paging for a terminal device, in some cases, the location of the terminal device is unknown, that is, it is unknown whether the terminal device is located within the coverage area of ​​the LP-WUS.

[0146] In summary, due to the simplified implementation, the sensitivity of LP-WUR is usually lower than that of the main receiver MR, especially when LP-WUR needs to maintain extremely low power consumption. This results in the coverage of LP-WUS being different from the coverage of the MR receiving signal (such as PDCCH, etc.), which will bring challenges to the synchronization, measurement, paging and other processes. How to determine whether the MR with LP-WUR is monitoring the LP-WUS, or whether it needs to switch to monitoring the pre-3GPP R17 (legacy) wake-up signals such as WUS, PEI, etc. due to exceeding the LP-WUS coverage range, and whether the network device wakes up the terminal device through LP-WUS or PEI / WUS (or instructs the terminal device to monitor the paging / downlink control signal) is a problem that needs to be solved.

[0147] Please refer to Figure 5, which shows a flowchart of a wake-up signal receiving method and a wake-up signal sending method provided by an embodiment of the present application. The method can be interactively executed by a terminal device and a network device, wherein the terminal device can be the terminal device 120 or the terminal device 130 in the network architecture shown in Figure 1, and the network device can be the network device 110 in the network architecture shown in Figure 1; the method can include the following steps:

[0148] Step 501: In a first time interval, a network device sends a first signal; correspondingly, in the first time interval, a terminal device receives the first signal through a first receiver of the terminal device; the first signal is used to wake up a second receiver of the terminal device.

[0149] The first signal may be a low power wake-up signal LP-WUS, the first receiver may be a low power wake-up receiver LP-WUR, and the second receiver may be a main receiver MR.

[0150] To sum up, the scheme shown in the embodiment of the present application determines the sending timing and monitoring timing of the first signal through the first time interval, which greatly reduces the number of invalid sending of wake-up signals by network devices and invalid monitoring of wake-up signals by terminal devices, helps network devices and terminal devices to determine whether to send and monitor wake-up signals, and achieves overall energy-saving optimization.

[0151] Based on the solution shown in FIG5 , please refer to FIG6 , which shows a flowchart of a wake-up signal receiving method and a wake-up signal sending method provided by one embodiment of the present application. The method can be interactively executed by a terminal device and a network device, wherein the terminal device can be the terminal device 120 or the terminal device 130 in the network architecture shown in FIG1 , and the network device can be the network device 110 in the network architecture shown in FIG1 ; the method can include the following steps:

[0152] Step 601, within a first time interval, the network device sends a first signal; accordingly, within the first time interval, the terminal device receives the first signal through the first receiver of the terminal device; the first signal is used to wake up the second receiver of the terminal device; the first time interval is determined by the time domain pattern.

[0153] The time domain pattern is a data structure used to determine the distribution position of the first time interval in the time domain.

[0154] That is, within a first time interval determined by the time domain pattern, the network device sends a first signal to the terminal device, and the terminal device receives the first signal through a first receiver; the first signal is used to wake up the second receiver of the terminal device.

[0155] The above-mentioned time domain pattern is similar to the frame structure in NR, and is used to determine the distribution position of the first time interval in the time domain. Determining the first time interval through the time domain pattern can effectively improve the accuracy and controllability of the network device sending the first signal and the terminal device monitoring the first signal, and further optimize the overall energy saving.

[0156] In some embodiments, the time domain pattern includes a first time domain pattern; the first time domain pattern is used to indicate the distribution of resource positions of the first resource in the time domain; and the first time interval is a time interval corresponding to the first resource.

[0157] In other words, the time interval corresponding to the first resource is the first time interval that needs to be clarified in the embodiments of this application, and the distribution of the resource location of the first resource in the time domain can be determined by the first time domain pattern included in the time domain pattern. Therefore, the specific distribution of the first time interval in the time domain can be determined by the first time domain pattern, further optimizing the technical solution of the embodiments of this application.

[0158] In some embodiments, the first resource is a resource from which the network device sends the first signal.

[0159] That is to say, the network device sends the first signal on the first resource. The embodiment of the present application further clarifies the correlation between the first signal and the first resource, which can improve the accuracy of the technical solution of the embodiment of the present application.

[0160] In some embodiments, the first resource is a resource corresponding to the first mode.

[0161] That is to say, the system can configure a first mode for the terminal device and / or network device, and the first resource can be a resource pre-configured for the first mode. The embodiment of the present application further clarifies the correlation between the working mode of the device and the first resource, which can improve the accuracy of the technical solution of the embodiment of the present application.

[0162] In some embodiments, the first mode is a mode in which the network device sends the first signal; and / or, the first mode is a mode in which the terminal device receives the first signal.

[0163] In the above embodiments, the network device in the system may have a first mode, and the network device may send a first signal in the first mode; or, the terminal device in the system may have a first mode, and the terminal device may receive a first signal in the first mode; or, the network device and the terminal device in the system may have a first mode, and the network device and the terminal device may send and receive the first signal in the first mode.

[0164] That is to say, in the embodiment of the present application, the working mode in which the network device sends the first signal and / or the terminal device receives the first signal can be defined as the first mode. The embodiment of the present application further clarifies the specific working mode corresponding to the first mode in the network device and the terminal device, which can improve the accuracy of the technical solution of the embodiment of the present application.

[0165] Step 602: The network device sends a second signal within a second time interval corresponding to the second resource; correspondingly, the terminal device receives the second signal through a second receiver of the terminal device within the second time interval corresponding to the second resource.

[0166] The time domain pattern further includes a second time domain pattern; the second time domain pattern is used to indicate the distribution of resource positions of the second resource in the time domain.

[0167] That is, the time domain pattern may include a first time domain pattern and a second time domain pattern. Accordingly, the time interval corresponding to the second resource is the second time interval that needs to be clarified in the embodiment of the present application, and the distribution of the resource location of the second resource in the time domain can be determined by the second time domain pattern included in the time domain pattern. Therefore, the specific distribution of the second time interval in the time domain can be determined by the second time domain pattern, further optimizing the technical solution of the embodiment of the present application.

[0168] That is, within the second time interval determined by the time domain pattern, the network device sends the second signal to the terminal device, and the terminal device receives the second signal through the second receiver.

[0169] In some embodiments, the first time-domain pattern and the second time-domain pattern may be two independent time-domain patterns.

[0170] Alternatively, the first time domain pattern and the second time domain pattern may be the same time domain pattern, that is, the time domain pattern may indicate the distribution of resources corresponding to two different signals in the time domain.

[0171] In some embodiments, the second signal includes a downlink signal for paging.

[0172] That is to say, the second signal can be a downlink signal used for paging, that is, other non-first signals can be used to page the terminal device UE, such as the legacy paging mechanism (i.e. directly transmitting Paging PDCCH) can be used to page the UE, or paging (Paging) can be indicated in advance through PEI.

[0173] In some embodiments, the second resource is a resource from which the network device transmits the second signal.

[0174] That is to say, the network device sends the second signal on the second resource. The embodiment of the present application further clarifies the correlation between the second signal and the second resource, which can improve the accuracy of the technical solution of the embodiment of the present application.

[0175] In some embodiments, the second resource is a resource corresponding to the second mode.

[0176] That is to say, the system can configure a second mode for the terminal device and / or network device, and the second resource can be a resource pre-configured for the second mode. The embodiment of the present application further clarifies the correlation between the working mode of the device and the second resource, which can improve the accuracy of the technical solution of the embodiment of the present application.

[0177] In some embodiments, the second mode is a mode in which the network device sends the second signal; and / or, the second mode is a mode in which the terminal device receives the second signal.

[0178] In the above embodiments, the network device in the system may have a second mode, in which the network device may send a second signal; or, the terminal device in the system may have a second mode, in which the terminal device may receive a second signal; or, the network device and the terminal device in the system may have a second mode, in which the network device and the terminal device may send and receive the second signal.

[0179] That is to say, the working mode in which the network device sends the second signal and / or the terminal device receives the second signal is defined as the second mode. The embodiment of the present application further clarifies the specific working mode corresponding to the second mode in the network device and the terminal device, which can improve the accuracy of the technical solution of the embodiment of the present application.

[0180] In some embodiments, the time domain pattern is predefined by a protocol; or, the time domain pattern is semi-statically configured by the network device; or, the time domain pattern is dynamically configured by the network device; or, the time domain pattern is semi-statically and dynamically configured by the network device.

[0181] In other words, the definition or configuration of the time domain pattern can be flexibly selected based on actual needs, which can effectively improve the flexibility and practicality of the technical solution of this application. For example, one or more time domain patterns can be predefined through a protocol; or one or more time domain patterns can be semi-statically configured through a network device; or one or more time domain patterns can be dynamically configured through a network device; or multiple time domain patterns can be semi-statically configured through a network device, and one or more of the multiple time domain patterns can be dynamically configured / enabled later through the network device.

[0182] It should be noted that the above-mentioned first signal can be a low-power wake-up signal LP-WUS, the above-mentioned first receiver can be a low-power wake-up receiver LP-WUR, the above-mentioned second receiver can be a main receiver MR, and the above-mentioned second signal can be a paging signal, such as Paging PDCCH.

[0183] When the network device supports a terminal device UE with a low-power wake-up receiver LP-WUR, it is not necessary to always wake up the terminal device UE by waking up the main receiver MR through the low-power wake-up signal LP-WUS. The main receiver MR of the terminal device UE can still be paged through the legacy mechanism, that is, directly transmitting the Paging PDCCH, or indicating Paging in advance through PEI.

[0184] Therefore, the time domain pattern can be used to determine whether the low power wake-up signal LP-WUS is needed to wake up the main receiver MR of the terminal device UE, that is, the first mode and the second mode can be switched to achieve the purpose of power saving of the terminal device.

[0185] The first mode may be a mode in which the network device wakes up the terminal device UE through the low power wake-up signal LP-WUS. At this time, the terminal device UE may monitor the LP-WUS continuously or in a duty cycle manner. That is, the first mode includes at least two paging cycles and at least two LP-WUS monitoring opportunities.

[0186] The second mode may be a mode in which the network device wakes up the terminal device UE through non-LP-WUS, for example, through the legacy mechanism, that is, directly transmitting the Paging PDCCH to page the main receiver MR of the terminal device UE, or indicating Paging in advance through PEI.

[0187] In summary, the network device and the terminal device UE only need to send and monitor LP-WUS respectively on the time domain resources corresponding to the first mode. On the time domain resources corresponding to the second mode, the network device does not send LP-WUS, but uses the legacy paging mechanism to page the terminal device UE. The terminal device UE turns on the main receiver MR and monitors the paging sent by the network device through the main receiver MR. The terminal device UE does not monitor LP-WUS.

[0188] In some embodiments, the time domain pattern may be used to determine the pattern distribution of the first pattern and the second pattern within a continuous time T, where the continuous time T is periodically distributed in the time domain.

[0189] Wherein, within a continuous time T, there is at least one first mode and at least one second mode.

[0190] Please refer to FIG7 , which shows a schematic diagram of a switching method for determining different modes based on a time domain pattern. A continuous time T in the time domain includes a first mode and a second mode, and the continuous time T is periodically distributed in the time domain.

[0191] Please refer to FIG8 , which shows another switching method for determining different modes based on time domain patterns. Within a continuous time T in the time domain, a first mode, two second modes, a first mode, and a second mode are sequentially included.

[0192] In some embodiments, the distribution of the first mode and the second mode in the time domain may be fixed:

[0193] It can be a fixed time domain pattern design agreed upon in the protocol: for example, the time domain ratio of the first mode and the second mode is 1:1;

[0194] It can be a time domain pattern of semi-static configuration of network devices.

[0195] In some embodiments, the distribution of the first mode and the second mode in the time domain can be flexibly configured:

[0196] It can be a time domain pattern of dynamic configuration of network devices;

[0197] It can be a time domain pattern of semi-static configuration of network devices.

[0198] In some embodiments, the first mode and the second mode may have multiple distributions in the time domain:

[0199] Multiple time domain pattern designs can be agreed upon by protocol, and the time domain patterns used by network devices can be dynamically or semi-statically configured;

[0200] The network device may semi-statically configure multiple time domain patterns, and the network device may dynamically configure the time domain pattern to be used.

[0201] Based on the solution shown in FIG5 , please refer to FIG9 , which shows a flowchart of a wake-up signal receiving method and a wake-up signal sending method provided by one embodiment of the present application. The method can be interactively executed by a terminal device and a network device, wherein the terminal device can be the terminal device 120 or the terminal device 130 in the network architecture shown in FIG1 , and the network device can be the network device 110 in the network architecture shown in FIG1 ; the method can include the following steps:

[0202] Step 901, within a first time interval, the network device sends a first signal; accordingly, within the first time interval, the terminal device receives the first signal through the first receiver of the terminal device; the first signal is used to wake up the second receiver of the terminal device; the first time interval is associated with a third time interval, wherein the third time interval is a time interval in which the terminal device receives the third signal through the second receiver.

[0203] That is, within a first time interval associated with the third time interval, the network device sends a first signal to the terminal device, and the terminal device receives the first signal through the first receiver; the first signal is used to wake up the second receiver of the terminal device.

[0204] The third time interval corresponds to the time interval during which the terminal device receives the third signal via the second receiver. During the third time interval, the network device stops sending the first signal to the terminal device, and the terminal device stops receiving the first signal via the first receiver. The second receiver can be activated to monitor for the wake-up signal, effectively improving the accuracy and controllability of the network device sending the first signal and the terminal device monitoring the first signal, further optimizing the energy conservation effect of the terminal device.

[0205] In some embodiments, the end time point of the first time interval is associated with the start time point of the third time interval.

[0206] The solution shown in the embodiment of the present application associates the end time point of the first time interval with the start time point of the third time interval, thereby providing a method for determining the first time interval through the third time interval.

[0207] In some embodiments, the starting time point of the current first time interval is associated with the ending time point of the previous third time interval; correspondingly, the ending time point of the current third time interval is associated with the starting time point of the next first time interval. The association method can be the same, or there can be a certain offset between the two time points.

[0208] In some embodiments, the end time point of the first time interval is the same as the start time point of the third time interval; or, there is a first offset between the end time point of the first time interval and the start time point of the third time interval.

[0209] An embodiment of the present application provides a specific method for associating the end time point of the first time interval with the start time point of the third time interval; that is, the end time point of the first time interval is associated with the start time point of the third time interval, and the end time point of the first time interval may be the same as the start time point of the third time interval, or the end time point of the first time interval may be offset by a certain duration based on the start time point of the third time interval.

[0210] For example, the end time point of the first time interval is the start time point of the third time interval; or, there is a certain duration offset between the end time point of the first time interval and the start time point of the third time interval; or, the total duration of the forward or backward offset of the end time point of the first time interval is the third time interval.

[0211] In some embodiments, the start time point of the first time interval is associated with the end time point of the third time interval.

[0212] The solution shown in the embodiment of the present application associates the starting time point of the first time interval with the ending time point of the third time interval, thereby providing a method for determining the first time interval through the third time interval.

[0213] In addition, the end time point of the current first time interval is associated with the start time point of the previous third time interval; correspondingly, the start time point of the current third time interval is associated with the end time point of the next first time interval. The association method can be the same, or there can be a certain offset between the two time points.

[0214] In some embodiments, the start time point of the first time interval is the same as the end time point of the third time interval; or, there is a second offset between the start time point of the first time interval and the end time point of the third time interval.

[0215] An embodiment of the present application provides a specific method for associating the end time point of the first time interval with the start time point of the third time interval; that is, the start time point of the first time interval is associated with the end time point of the third time interval, and the start time point of the first time interval may be the same as the end time point of the third time interval, or the start time point of the first time interval may be offset by a certain duration based on the end time point of the third time interval.

[0216] For example, the starting time point of the first time interval is the ending time point of the third time interval; or, there is a certain duration offset between the starting time point of the first time interval and the ending time point of the third time interval; or, the total duration of the forward or backward offset of the starting time point of the first time interval is the third time interval.

[0217] In some embodiments, the third signal includes: a downlink signal for measurement, and / or a downlink signal for synchronization.

[0218] That is to say, the third signal may be a downlink signal for measurement, or a downlink signal for synchronization, or may include a downlink signal for measurement and a downlink signal for synchronization; wherein, the embodiment of the present application selects a downlink signal for measurement and / or synchronization as the third signal, and associates the reception and transmission time interval of the first signal with the reception and transmission time interval of the measurement and / or synchronization downlink signal, thereby avoiding the overlap of time domain resources of the first signal and the measurement and / or synchronization downlink signal, and improving resource utilization.

[0219] In some embodiments, the third time interval is predefined by the protocol; or, the third time interval is semi-statically configured by the network device; or, the third time interval is dynamically configured by the network device; or, the third time interval is semi-statically configured + dynamically configured by the network device.

[0220] That is to say, the third time interval can be agreed upon by the protocol or configured by the network device (for example, it can be a semi-static configuration and / or dynamic configuration). The definition or configuration of the third time interval can be flexibly selected according to actual needs, thereby improving the flexibility and practicality of the technical solution of this application.

[0221] In some embodiments, the third time interval includes: one or more time slots; or, one or more frames; or, one or more discontinuous reception cycles.

[0222] That is to say, the third time interval can be the time slot where the third signal is located, or the frame where it is located, or a DRX cycle where it is located, or x time slots / frames / DRX cycles where it is located. It can be flexibly selected according to actual needs, which can effectively improve the flexibility and practicality of the technical solution of this application.

[0223] Among them, the above-mentioned first signal can be a low-power wake-up signal LP-WUS, the above-mentioned first receiver can be a low-power wake-up receiver LP-WUR, the above-mentioned second receiver can be a main receiver MR, and the above-mentioned third signal can be a downlink signal for MR to perform measurement and / or time-frequency synchronization.

[0224] Due to the LP-WUR implementation and its low sensitivity, relying solely on it for measurement and time-frequency synchronization is challenging. Therefore, a feasible implementation involves combining LP-WUR with MR for measurement and time-frequency synchronization, essentially relaxing the MR's measurement. The terminal device must enable the MR for measurement and time-frequency synchronization. Regardless of whether the LP-WUS wakes up the MR, the MR must be enabled to monitor downlink signals. In this context, the MR's measurement behavior can be used to determine whether to monitor the LP-WUS.

[0225] Please refer to Figure 10, which shows a schematic diagram of LP-WUS monitoring based on MR measurement / synchronization. During the first time unit in which the MR performs measurement and / or time-frequency synchronization, the LP-WUS is no longer monitored via the LP-WUR, but the MR is enabled to monitor the wake-up signal. During time units in which the MR does not need to perform measurement and / or time-frequency synchronization, the LP-WUS is monitored via the LP-WUR.

[0226] When the LP-WUR detects an LP-WUS signal sent to the UE or the terminal group to which the UE belongs, it wakes up the MR to listen for paging signals sent by the network device. While the LP-WUR wakes up the MR and the MR listens for downlink signals, the LP-WUR can continue to listen for LP-WUS or stop listening for LP-WUS.

[0227] Among them, the first time unit can be the time slot in which measurement and / or time-frequency synchronization is performed, or the frame in which it is located, or a DRX cycle in which it is located, or x time slots / frames / DRX cycles in which it is located; the first time unit can be agreed upon by the protocol, or configured by the network device (for example, it can be a semi-static configuration and / or dynamic configuration).

[0228] In some embodiments, based on the solution of step 901 above, during the fourth time interval, the network device does not perform the operation of sending the first signal, and the network device sends a downlink signal for paging received by the second receiver to the terminal device; accordingly, the terminal device does not perform the operation of receiving the first signal through the first receiver, and the terminal device can receive the downlink signal for paging sent by the network device through the second receiver;

[0229] The fourth time interval is a time interval for receiving a downlink signal for paging through the second receiver.

[0230] That is to say, the time interval for receiving the downlink signal for paging through the second receiver is defined as the fourth time interval. During the third time interval and the fourth time interval, the network device stops sending the first signal to the terminal device, and the terminal device stops receiving the first signal through the first receiver. The second receiver can be started to monitor the wake-up signal.

[0231] The third time interval corresponds to a time interval during which the terminal device receives a third signal through the second receiver, and the fourth time interval corresponds to a time interval during which the second receiver receives a downlink signal for paging.

[0232] Further limiting the timing of the terminal device monitoring the first signal by the third time interval and the fourth time interval can effectively improve the accuracy and controllability of the network device sending the first signal and the terminal device monitoring the first signal, and further optimize the energy-saving effect of the terminal device.

[0233] In other embodiments, the network device may also perform the operation of sending the first signal within the fourth time interval, and correspondingly, the terminal device may also perform the operation of receiving the first signal through the first receiver within the fourth time interval.

[0234] In some embodiments, the start time point of the fourth time interval is the same as the end time point of the third time interval; or, there is a third offset between the start time point of the fourth time interval and the end time point of the third time interval.

[0235] This embodiment of the present application is used to further illustrate the correlation between the fourth time interval and the third time interval:

[0236] The starting time point of the fourth time interval may be the same as the ending time point of the third time interval;

[0237] A third offset may exist between the start time point of the fourth time interval and the end time point of the third time interval.

[0238] In which, when a fourth time interval exists, the start time point of the current first time interval is associated with the end time point of the previous fourth time interval; correspondingly, the end time point of the current fourth time interval is associated with the start time point of the next first time interval. The association method can be the same, or there can be a certain offset between the two time points.

[0239] It should be noted that the above-mentioned third offset can be the offset of the starting point of the fourth time interval relative to the end point of the third time interval; or, the fourth time interval is the time interval corresponding to a period of time starting from the end point of the third time interval and offset backward.

[0240] For example, the end time point of the third time interval is the start time point of the fourth time interval; or, there is a certain duration offset between the end time point of the third time interval and the start time point of the fourth time interval; or, the total duration of the forward or backward offset of the end time point of the third time interval is the fourth time interval.

[0241] In some embodiments, the fourth time interval includes: one or more time slots; or, one or more frames; or, one or more discontinuous reception cycles.

[0242] That is to say, the fourth time interval can be the time slot where the downlink signal used for paging is located, or the frame where it is located, or a DRX cycle where it is located, or x time slots / frames / DRX cycles where it is located. It can be flexibly selected according to actual needs to improve the flexibility and practicality of the technical solution of this application.

[0243] In some embodiments, the fourth time interval is predefined by a protocol; or, the fourth time interval is semi-statically configured by the network device; or, the fourth time interval is dynamically configured by the network device; or, the fourth time interval is semi-statically configured + dynamically configured by the network device.

[0244] That is to say, the fourth time interval can be agreed upon by the protocol or configured by the network device (for example, it can be a semi-static configuration and / or dynamic configuration). The definition or configuration of the fourth time interval can be flexibly selected according to actual needs, thereby improving the flexibility and practicality of the technical solution of this application.

[0245] It should be noted that the above-mentioned fourth time interval is defined by the protocol or configured by the network, which may mean that the time domain offset and / or duration of the fourth time interval relative to the third time interval is predefined by the protocol or configured by the network device; or, the fourth time interval here is defined by the protocol or configured by the network, which may also mean that the starting time domain position and / or duration of the fourth time interval is predefined by the protocol or configured by the network device.

[0246] Among them, the above-mentioned first signal can be a low-power wake-up signal LP-WUS, the above-mentioned first receiver can be a low-power wake-up receiver LP-WUR, the above-mentioned second receiver can be a main receiver MR, and the above-mentioned third signal can be a downlink signal for MR to perform measurement and / or time-frequency synchronization.

[0247] Please refer to FIG. 11 , which shows a schematic diagram of LP-WUS monitoring based on MR measurement / synchronization / paging determination.

[0248] As shown in Figure 11, during the first time unit in which the MR performs measurement and / or time-frequency synchronization, and during the second time unit after the MR performs measurement and / or time-frequency synchronization, the LP-WUS is no longer monitored through the LP-WUR, but the MR is started to monitor the wake-up signal; in the time unit in which the MR does not need to perform measurement and / or time-frequency synchronization, the LP-WUS is monitored through the LP-WUR, and when the LP-WUS signal sent to the UE or the terminal group to which the UE belongs is monitored, the MR is awakened to monitor the paging sent by the network device. While the LP-WUR wakes up the MR device and the MR device monitors the downlink signal, the LP-WUR can continue to monitor the LP-WUS, or stop monitoring the LP-WUS.

[0249] Among them, the first time unit can be the time slot in which measurement and / or time-frequency synchronization is performed, or the frame in which it is located, or a DRX cycle in which it is located, or x time slots / frames / DRX cycles in which it is located; the first time unit can be agreed upon by the protocol, or configured by the network device (for example, it can be a semi-static configuration and / or dynamic configuration).

[0250] Among them, the second time unit can be equal to or different from the first time unit, or can be implemented based on a delay timer; the second time unit can be x time slots / frames / DRX cycles, etc.; the second time unit can be a time offset based on the first time unit; the second time unit can be agreed upon by the protocol, or configured by the network device (for example, it can be a semi-static configuration and / or dynamic configuration).

[0251] Based on the solution shown in FIG5 , please refer to FIG12 , which shows a flowchart of a wake-up signal receiving method and a wake-up signal sending method provided by one embodiment of the present application. The method can be interactively executed by a terminal device and a network device, wherein the terminal device can be the terminal device 120 or the terminal device 130 in the network architecture shown in FIG1 , and the network device can be the network device 110 in the network architecture shown in FIG1 ; the method can include the following steps:

[0252] Step 1201, within a first time interval, the network device sends a first signal; accordingly, within the first time interval, the terminal device receives the first signal through the first receiver of the terminal device; the first signal is used to wake up the second receiver of the terminal device; the first time interval is determined by period information, and the above-mentioned period information is used to indicate the first period for receiving the first signal.

[0253] That is to say, within the first time interval determined by the period information, the network device sends a first signal to the terminal device, and the terminal device receives the first signal through the first receiver; the first signal is used to wake up the second receiver of the terminal device, and the period information is used to indicate the first period for receiving the first signal.

[0254] The first time interval is determined by periodic information, and the above periodic information can be used to indicate the first period for receiving the first signal. When in the first period for receiving the first signal, the network device can send the first signal, and the terminal device can receive the first signal through the first receiver of the terminal device; conversely, the network device stops sending the first signal, and the terminal device stops receiving the first signal through the first receiver of the terminal device, thereby improving the accuracy and controllability of the network device sending the first signal and the terminal device monitoring the first signal, and further optimizing the energy-saving effect of the terminal device.

[0255] In some embodiments, a first cycle includes one or more activation duration intervals and one or more deactivation time intervals; the first time interval is associated with the activation duration interval.

[0256] That is to say, there can be one activation duration interval and one deactivation time interval within a first cycle; or, one activation duration interval and multiple deactivation time intervals; or, multiple activation duration intervals and one deactivation time interval; or, multiple activation duration intervals and multiple deactivation time intervals; the combination of time intervals within the above-mentioned first cycle can be flexibly configured according to actual needs, thereby improving the flexibility and practicality of the technical solution of the present application.

[0257] The first time interval is associated with the activation duration interval.

[0258] In some embodiments, the first time interval comprises an activation duration interval.

[0259] The embodiment of the present application is used to illustrate a specific manner in which the first time interval is associated with the activation duration interval. That is, the first time interval includes at least one activation duration interval.

[0260] When the first time interval includes an activation duration interval, the first time interval can be a general concept, referring to multiple time intervals, each of which corresponds to an activation duration interval in the first period. In other words, the first time interval generally refers to time intervals such as the activation duration interval in the first period.

[0261] For example, assuming that a first cycle includes two activation duration intervals, and the terminal device needs to receive the first signal within multiple first cycles, then the above-mentioned first time interval generally refers to each activation duration interval in the multiple first cycles.

[0262] In some embodiments, at least one of the duration of the first cycle, the duration of the activation duration interval, and the duration of the deactivation time interval is predefined by a protocol; or, at least one of the duration of the first cycle, the duration of the activation duration interval, and the duration of the deactivation time interval is semi-statically configured by the network device; or, at least one of the duration of the first cycle, the duration of the activation duration interval, and the duration of the deactivation time interval is dynamically configured by the network device; or, at least one of the duration of the first cycle, the duration of the activation duration interval, and the duration of the deactivation time interval is semi-statically + dynamically configured by the network device.

[0263] That is to say, the definition or configuration of the duration of the first cycle, the duration of the activation duration interval, and the duration of the deactivation time interval can be agreed upon by the protocol, or configured by the network device (for example, it can be a semi-static configuration and / or dynamic configuration), and can be flexibly selected according to actual needs to improve the flexibility and practicality of the technical solution of this application.

[0264] In some embodiments, the first period is associated with a second period during which the second receiver performs measurements.

[0265] That is, the first period is associated with the second period in which the second receiver performs measurement. The embodiment of the present application is used to illustrate the correlation between the first period and the second period. As mentioned above, a first period includes one or more activation duration intervals and one or more deactivation time intervals. Therefore, the correlation here can be:

[0266] The deactivation time interval in the first cycle is associated with the time interval for measurement in the second cycle; and / or,

[0267] The activation duration interval in the first cycle is associated with a time interval not used for measurement in the second cycle.

[0268] In some embodiments, at least one of the duration of the first period, the duration of the activation duration interval, and the duration of the deactivation time interval is associated with a second period during which the second receiver performs measurements.

[0269] The embodiment of the present application is used to illustrate the specific manner in which the first period is associated with the second period for measurement by the second receiver. The association here can be a duration, that is, at least one of the duration of the first period, the duration of the activation duration interval, and the duration of the deactivation time interval, is associated with the second period for measurement by the second receiver.

[0270] In some embodiments, the duration of the first cycle is an integer multiple of the duration of the second cycle; or, the duration of the second cycle is an integer multiple of the duration of the first cycle.

[0271] The embodiments of the present application are used to illustrate the specific manner in which the duration of the first cycle is associated with the duration of the second cycle. The duration of the first cycle and the duration of the second cycle can be integer multiples of each other, that is, the duration of the first cycle is an integer multiple of the duration of the second cycle; or, the duration of the second cycle is an integer multiple of the duration of the first cycle (or, the duration of the first cycle is a factor of the duration of the second cycle).

[0272] Specifically, for example, if the duration of the first cycle is 8 time slots, the duration of the second cycle may be 1 time slot, 2 time slots, 4 time slots, 8 time slots, 16 time slots, 24 time slots, etc.

[0273] In some embodiments, the duration of the activation duration interval is an integer multiple of the duration of the time interval used for measurement in the second cycle; or, the duration of the time interval used for measurement in the second cycle is an integer multiple of the duration of the activation duration interval.

[0274] The embodiment of the present application is used to illustrate the specific manner in which the duration of the first cycle is associated with the duration of the second cycle. The duration of the activation duration interval and the duration of the time interval used for measurement in the second cycle can be integer multiples of each other, that is, the length of the activation duration interval is an integer multiple of the length of the time interval used for measurement in the second cycle; or, the length of the time interval used for measurement in the second cycle is an integer multiple of the length of the activation duration interval.

[0275] Specifically, for example, if the duration of the activation duration interval is 8 time slots, the duration of the time interval used for measurement in the second cycle can be 1 time slot, 2 time slots, 4 time slots, 8 time slots, 16 time slots, 24 time slots, etc.

[0276] In some embodiments, the duration of the deactivation time interval is an integer multiple of the duration of the time interval not used for measurement in the second cycle; or, the duration of the time interval not used for measurement in the second cycle is an integer multiple of the duration of the deactivation time interval.

[0277] The embodiments of the present application are used to illustrate the specific manner in which the duration of the first cycle is associated with the duration of the second cycle. The duration of the deactivation duration interval and the duration of the time interval in the second cycle that is not used for measurement can be integer multiples of each other, that is, the length of the deactivation duration interval is an integer multiple of the length of the time interval in the second cycle that is not used for measurement; or, the length of the time interval in the second cycle that is not used for measurement is an integer multiple of the length of the deactivation duration interval.

[0278] Specifically, for example, if the deactivation duration interval is 8 time slots, the length of the time interval not used for measurement in the second cycle can be 1 time slot, 2 time slots, 4 time slots, 8 time slots, 16 time slots, 24 time slots, etc.

[0279] The first signal may be a low power wake-up signal LP-WUS, the first receiver may be a low power wake-up receiver LP-WUR, and the second receiver may be a main receiver MR.

[0280] The transmission and reception of LP-WUS signals can be distributed periodically over time, that is, the network device periodically transmits LP-WUS signals and the terminal device periodically monitors LP-WUS signals. In other words, the network device and the terminal device periodically activate / deactivate the transmission and monitoring of LP-WUS signals.

[0281] Please refer to Figure 13, which shows a schematic diagram of determining LP-WUS monitoring based on the LP-WUS activation period. The LP-WUS is periodically activated / deactivated. Specifically, the LP-WUS is activated once every period T, and the LP-WUS activation duration is D. During the time period T, the LP-WUS deactivation duration A is equal to TA.

[0282] Among them, the time period T can be agreed upon by the protocol or configured by the network device; the activation duration D of the LP-WUS can be agreed upon by the protocol or configured by the network device; the deactivation time A of the LP-WUS can be agreed upon by the protocol or configured by the network device.

[0283] At least one of T, D, and A is associated with the MR measurement period. For example, the activation period T of the LP-WUS is equal to the MR measurement period, or is an integer multiple of the MR measurement period, or is a factor of the MR measurement period.

[0284] Among them, at least one of T, D, and A is configured by the network device.

[0285] During the LP-WUS activation duration D, the network device sends the LP-WUS to the terminal device, which receives it via the LP-WUR. The LP-WUS is used to wake up the terminal device's main receiver MR. During the LP-WUS deactivation duration A, the network device stops sending the LP-WUS to the terminal device, and the terminal device stops receiving the LP-WUS via the LP-WUR.

[0286] In other embodiments, based on the solution shown in FIG. 13 , there may be multiple LP-WUS activation opportunities within the time period T, that is, there may be multiple LP-WUS activation duration distributions within the time period T.

[0287] Please refer to Figure 14, which shows another schematic diagram of determining LP-WUS monitoring based on the LP-WUS activation period. Within the time period T, there are two LP-WUS activation opportunities, that is, within the time period T, there are two LP-WUS activation duration distributions.

[0288] During the two LP-WUS activation periods, the network device sends the LP-WUS to the terminal device, which receives it via the LP-WUR. The LP-WUS is used to wake up the terminal device's main receiver (MR). During the two LP-WUS deactivation periods, the network device stops sending the LP-WUS to the terminal device, and the terminal device stops receiving the LP-WUS via the LP-WUR.
