[0025] Before introducing the technical proposal of this application, some background technical knowledge relating to this application will be introduced and explained. The following related technologies can be optionally combined with the technical proposal of the embodiment of this application as selectable technical proposals, and all of them are included within the scope of protection of the embodiment of this application. The embodiment of this application includes at least some of the following:

[0026] 1) Energy-saving design of terminal equipment To reduce power consumption in terminal equipment, both LTE and NR systems include a Discontinuous Reception (DRX) mechanism. This allows terminal equipment to conserve power by switching to an intermittent reception state when there is no data to be received, rather than keeping the receiver constantly on. As NR technology evolves, the demands on power conservation in user equipment (UE) are becoming even stricter. For example, in existing DRX mechanisms, during each on-duration, the UE needs to continuously detect the Physical Downlink Control Channel (PDCCH) to determine whether the base station is scheduling data transmission to it. However, for most UEs, periodic wake-ups are necessary to monitor possible downlink transmissions, even though they may not need to receive data transmissions for extended periods. For this type of UE, there is still room for further optimization in terms of energy conservation in terminal equipment. The R16 standard introduces energy-saving signals to further reduce energy consumption in terminal devices when connected under Radio Resource Control (RRC) conditions. These signals are used in conjunction with the DRX mechanism, and terminal devices receive instructions for the energy-saving signal before the on-duration. If there is data transmission in the upcoming on-duration, the network uses the energy-saving signal to "wake up" the terminal device and monitors the PDCCH during the upcoming on-duration. Otherwise, the network uses the energy-saving signal to instruct the terminal device to continue "sleeping," and the terminal device does not need to monitor the PDCCH during the upcoming on-duration. Compared to the existing DRX mechanism, energy savings can be achieved because terminal devices can omit PDCCH monitoring during the on-duration period when there is no data transmission. The R17 standard establishes a project to enhance energy efficiency in terminal equipment, further standardizing energy efficiency in terminal equipment during RRC idle (IDLE) and RRC inactive (INACTIVE) states. Power consumption in terminal equipment during RRC IDLE and RRC INACTIVE states is primarily due to the reception of periodic intermittent paging, which includes power consumption from time-frequency synchronization recovery and automatic gain control (AGC) performed before the paging timing arrives, and power consumption from the detection of paging PDCCH during the paging timing period. To reduce power consumption during the paging reception process, the R17 standard introduces an energy-saving signal for paging reception called Paging Early Indication (PEI), which is used to indicate whether the terminal equipment needs to receive paging at the paging timing before the paging timing arrives.

[0027] 2) PEI design in R17

[0028] JPEG2026529474000028.jpg6160PEI-O is a collection of multiple PDCCH monitoring timings. Specifically, 1. If the number of PDCCH monitoring timings (nrofPDCCH-MonitoringOccasionPerSSB-InPO) corresponding to the Synchronization Signal Block (SSB) within the paging timing is not set, the PEI monitoring timing will be a set of S consecutive PDCCH monitoring timings. Here, S is the number of SSBs actually transmitted, determined by the time-domain position (ssb-PositionsInBurst) of the SSBs transmitted in a half-frame containing the synchronization signal (SS) / PBCH block in SIB1. In PEI monitoring timing, the quasi-colocation (QCL) of the Kth PEI PDCCH monitoring timing is the same as the Kth PDCCH monitoring timing being paged within the paging timing (PO) (the QCL reference is SSB). 2. In unlicensed spectra, the PEI monitoring timing is a set of (S*X) consecutive PDCCH monitoring timings. Here, S is the actual number of transmitted SSBs determined by ssb-PositionsInBurst in SIB1. If nrofPDCCH-MonitoringOccasionPerSSB-InPO is set, X is this setting value; otherwise, X=1. The (x*S+K)th PDCCH monitoring timing within a PEI monitoring timing corresponds to the Kth SSB being transmitted, where x=0, 1, ..., X-1, K=1, 2, ..., S. If X>1, once a terminal device detects a PEI within a PEI monitoring timing, the terminal device does not need to continue monitoring subsequent monitoring timings associated with this PEI monitoring timing.

[0029] JPEG2026529474000029.jpg The 686 network allows for multiple POs (Points of Interaction) to be assigned to each Paging Frame (PF). If each PEI corresponds to one PO, a large number of independent PEIs are generated, increasing the PEI overhead. On the other hand, PEIs corresponding to these POs may overlap in the time domain. In Rel-15 / 16, one Wake Up Signal (WUS) can be associated with one or more POs. When designing the PEIs, a mapping mechanism similar to WUS was ultimately decided upon to reduce PEI overhead and avoid PEI overlap. That is, one PEI can be associated with one or more POs. The specific design is as follows. This enables support for a single PEI to be associated with a high-level configuration parameter (POnumPerPEI) number of POs. 1. A PEI (PerPEI) can have POnum (PerPEI) points associated with it. Each PO can reside in one or more PFs. The maximum number of PFs associated with a single PEI is 2. 2. POnumPerPEI is N*N S This is the factor, where N is the number of paging frames in one paging cycle. S POnumPerPEI is the number of POs within a single paging frame. POnumPerPEI can be set via the System Information Block (SIB), and its value ranges from {1, 2, 4, 8}.

[0030] Figure 2 shows a schematic diagram of the determination of the PEI-O position according to an exemplary embodiment of the present invention. The terminal device determines the position of the PEI-O corresponding to the PO based on a reference point and an offset value (from the reference point to the first PDCCH monitoring timing of the PEI-O). 1. First, determine the reference frame, and use the starting point of the reference frame as the reference point. Based on the first of all PFs associated with the PEI (if one 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. The frame-level offset value from the first of all PFs associated with the PEI to the reference frame is set by the SIB. 2. Determine the position of the first PDCCH monitoring timing within PEI-O based on the reference point and symbol level offset values. The symbol-level offset from the reference point to the first PDCCH monitoring timing in PEI-O can be set by the SIB. The specific offset value is provided by the offset amount (expressed in symbols) from the beginning of the PEI-O reference frame to the beginning of the first PDCCH monitoring timing in PEI-O.

[0031] 3) LP-WUS / WUR in 3GPP R18 The 3GPPR18 research project explores further energy-saving measures for terminal devices. The research introduces a Low Power Wake Up Receiver (LP-WUR), designs a Low Power Wake Up Signal (LP-WUS), monitors the LP-WUS signal using the LP-WUR, and wakes up the main receiver when it receives a wake-up signal from a network device. Specifically, when monitoring the wake-up signal using the LP-WUR, the main receiver (MR: Main Radio) can remain in an Ultra Deep Sleep state, achieving overall energy savings for the terminal device.

[0032] When conducting research on LP-WUS / WUR, the RAN1 working group has reached a preliminary agreement regarding the accuracy of the LP-WUR oscillator and will consider the following four options. Option 1: The oscillator has a maximum frequency error of 200 ppm and a frequency drift of 0.1 ppm / S. Option 2: The oscillator has a maximum frequency error of 50 ppm and a frequency drift of 0.1 ppm / S. Option 3: The oscillator has a maximum frequency error of 10 ppm and a frequency drift of 0.05 ppm / S. Option 4: The oscillator has a maximum frequency error of 5 ppm and a frequency drift of 0.05 ppm / S. Consider that the LP-WUR's Real Time Clock (RTC) has a maximum frequency error of 20 ppm and a frequency drift of 0.1 ppm / s.

[0033] As shown in Table 1, the RAN1 Working Group reached the following conclusions regarding the power consumption model of the LP-WUR (for research and evaluation purposes only; the final LP-WUR design may include multiple types or only one type).

[0034] [Table 1]

[0035] JPEG2026529474000034.jpg109170

[0036] As of the time of the JPEG2026529474000035.jpg596RAN1#113 meeting, the following agreement was reached regarding the measurement of Radio Resource Management (RRM) for LP-WUR.

[0037] 1. For RRM serving cell measurements performed by LP-WUR based on a reference signal, RAN1 will determine at least the following indicators, including feasibility, complexity, and power consumption, to aid in further investigation and evaluation: Low Power Received Signal Strength Indicator (LP-RSSI) or Energy Detection: Linear average value of total power received by RSSI resource. Low Power Reference Signal Received Power (LP-RSRP): The linear average of the received power of the reference signal or a portion of the signals transmitted by the signal source. Low Power Signal to Interference plus Noise Ratio (LP-SINR) = LP - RSRP / (power of interference and noise). Low Power Reference Signal Receiving Quality (LP-RSRQ) = [N ×] LP-RSRP / LP-RSSI. Here, N is a factor used to evaluate the difference in resource size between LP-RSRP and LP-RSSI. AGC accuracy requires at least a 4-bit analog-to-digital converter (ADC). The reference signal used for measurement may be an SSB, LP-WUS waveform sequence, or Low Power Synchronization Signal (LP-SS), where SSB includes a Primary Synchronization Signal (PSS), a Secondary Synchronization Signal (SSS), a Physical Broadcast Channel (PBCH), and a Demodulation Reference Signal (DMRS).

[0038] 2. In Idle / Inactive mode, study the offloading of RRM measurements of the serving cell to LP-WUR under certain conditions and consider the relaxation of RRM measurements of the serving cell / adjacent cell in MR. LP-WUR measurements utilize periodic reference signals such as SSB (PSS / SSS / PBCH DMRS), LP-WUS waveform sequences, and LP-SS. MR performs RRM measurement, and here, Option 1: If MR takes into account the relaxation of RRM measurement, the relaxed period is used. Option 2: Perform the RRM measurement of the MR only if certain conditions are met, for example, the LP-WUR measurement based on the reference signal falls below a threshold.

[0039] In the case of JPEG2026529474000036.jpg111701.IDLE / INACTIVE state, the RAN1 Working Group considered and studied the following methods for activating / deactivating LP-WUS monitoring of the UE by LP-WUR. Option 1: The gNB transmits conventional paging instructions and LP-WUS. Depending on the implementation of the UE, it is determined whether to activate or deactivate the monitoring of the LP-WUS wake-up signal. You may choose to activate or deactivate the channel depending on channel conditions, such as whether coverage is sufficient. Option 2: The gNB transmits conventional paging instructions and LP-WUS. Based on pre-set criteria, it determines whether to activate or deactivate the monitoring of the LP-WUS wake-up signal. You may choose to activate or deactivate the channel depending on channel conditions, such as whether coverage is sufficient. Option 3: Within the cell, the active / inactive status of monitoring for LP-WUS is determined based on signaling.

[0040] 2. When the RRC CONNECTED state is reached, LP-WUS monitoring may be activated or deactivated by at least one of the following methods: This is done through gNB RRC signaling, and is based on UE support, or not based on UE support. This is due to active / inactive signaling of gNB's Layer 1 / Layer 2 (L1 / L2) LP-WUS, and may or may not be based on UE support. Based on pre-set criteria such as a timer. The terminal device's monitoring of LP-WUS must be recognizable by the gNB.

[0041] 3GPP R18 is conducting research on low-power wake-up signals (LP-WUS) and low-power wake-up receivers (LP-WUR). Currently, it is in the SI (Systems Initiative) stage, and the standards have not yet been finalized. The wake-up receiver is characterized by extremely low cost, extremely low complexity, and extremely low power consumption. It receives the wake-up signal primarily by a method based on envelope detection. Therefore, the LP-WUS received by the wake-up receiver differs from the modulation scheme and waveform of the signal carried by the PDCCH as defined in the existing 3GPP R16 and R17 standards. The wake-up signal is primarily an envelope signal modulated with amplitude shift keying (ASK) relative to the carrier signal. Demodulation of the envelope signal can also be passive, as it is primarily performed by energy-efficient circuits provided by the radio frequency signal. The wake-up receiver may be powered by terminal equipment, and in either power supply method, the receiver consumes significantly less power compared to conventional receivers in the UE. The wake-up receiver may be integrated into the UE as an add-on module to the UE receiver, or it may be a standalone wake-up function module for the UE. Figure 3 shows a block diagram of a terminal equipment receiver system according to an exemplary embodiment of the present invention. The wake-up receiver receives a wake-up signal and can instruct the UE to turn on its main receiver if the UE needs to turn on the receiver. Otherwise, the UE's main receiver may remain off.

[0042] The LP-WUS signal may be used to wake up the MR. Specifically, the UE's LP-WUR monitors the LP-WUS. Upon receiving an LP-WUS signal transmitted to a terminal device or the terminal group to which a terminal device belongs, the LP-WUR wakes up the MR. Generally, the LP-WUR may continuously monitor the LP-WUS or perform intermittent LP-WUS monitoring using a duty cycle method. If a network device needs to communicate with a terminal device UE that includes LP-WUS, it may first send an LP-WUS signal to wake up the terminal device, turn on the terminal device UE's main receiver MR, and have the main receiver MR receive signals such as PDCCH and PDSCH transmitted by the network device. Considering factors such as the implementation methods and sensitivity differences between LP-WUR and MR, it is difficult for LP-WUR and MR to achieve the same coverage effect. In other words, the coverage range of an LP-WUR receiving LP-WUS is often different from the coverage range of an MR receiving PDCCH, PDSCH, etc.

[0043] For UEs that do not include LP-WUR (legacy UEs) prior to 3GPP R17, network devices can page UEs using Paging PDCCH. For UEs that include LP-WUS, as introduced in 3GPP R18, network devices can wake up the UE's MR via LP-WUS and then page the UE. The UE can be paged via LP-WUS, or it can be paged via Paging PDCCH after the UE's MR has been woken up.

[0044] Figure 4 shows the coverage range of the LP-WUS signal and Paging PDCCH signal according to an exemplary embodiment of the present application. Terminal devices within a cell where the same network equipment is located may be located within or outside the LP-WUS coverage range.

[0045] If a terminal device (UE) is within the coverage range of LP-WUS, LP-WUR can monitor LP-WUS. When a UE monitors LP-WUS transmitted to itself or its terminal group, it wakes up the MR and monitors the paging PDCCH or PDSCH. At this time, network devices can wake up terminal devices via LP-WUS. If the terminal device UE is located outside the LP-WUS coverage range, the UE cannot wake up the MR using the LP-WUS signal. In this case, the UE needs to monitor whether or not network devices are sending paging signals to it using the MR.

[0046] For network devices, when it is necessary to initiate paging to a terminal device, there may be situations where the location of this terminal device is unknown, that is, whether or not this terminal device is within the coverage area of ​​LP-WUS.

[0047] As described above, the implementation is simplified, and the sensitivity of the LP-WUR is typically lower than that of the main receiver MR, especially when the LP-WUR needs to maintain extremely low power consumption. As a result, the coverage range of the LP-WUS differs from that of the MR received signal (such as PDCCH), creating challenges in processes such as synchronization, measurement, and paging. How to decide whether the MR, including the LP-WUS, monitors the LP-WUS or switches to monitoring legacy wake-up signals prior to 3GPP R17, such as WUS or PEI, because the LP-WUS coverage range has been exceeded, and whether network equipment wakes up terminal equipment by LP-WUS or by PEI / WUS (or instructs terminal equipment to monitor paging / downlink control signals) are issues that need to be addressed.

[0048] Figure 5 shows a flowchart of a method for receiving and transmitting a wake-up signal provided by an embodiment of the present invention. This method can be performed by interaction between a terminal device and a network device. Here, the terminal device may be terminal device 120 or terminal device 130 in the network architecture shown in Figure 1, and the network device may be network device 110 in the network architecture shown in Figure 1. This method may include the following steps.

[0049] In step 501, within the first time segment, the network device transmits a first signal. In response, within the first time segment, the terminal device receives the first signal with its first receiver, and this first signal is used to wake up the terminal device's second receiver. Here, 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. As described above, according to the technical solution shown in one embodiment of the present application, by determining the transmission timing and monitoring timing of the first signal in the first time segment, the number of unnecessary wake-up signal transmissions by network devices and the number of unnecessary wake-up signal monitorings by terminal devices are significantly reduced. This helps network devices and terminal devices decide whether or not to transmit and monitor wake-up signals, thereby optimizing overall energy saving.

[0050] Based on the proposed technology shown in Figure 5 above, and referring to Figure 6, Figure 6 shows a flowchart of a method for receiving and transmitting a wake-up signal provided by one embodiment of the present invention. This method can be performed by interaction between a terminal device and a network device. Here, the terminal device may be terminal device 120 or terminal device 130 in the network architecture shown in Figure 1, and the network device may be network device 110 in the network architecture shown in Figure 1. This method may include the following steps.

[0051] In step 601, within the first time segment, a network device transmits a first signal. In response, within the first time segment, a terminal device receives the first signal with its first receiver, which is used to wake up the terminal device's second receiver. This first time segment is determined by a time-domain pattern. Here, the time-domain pattern described above is a data structure for determining the distribution location of the first time segment in the time domain. In other words, within a first time segment determined by a time-domain pattern, network equipment transmits a first signal to terminal equipment, terminal equipment receives the first signal via a first receiver, and this first signal is used to wake up a second receiver in the terminal equipment. The time-domain pattern described above is similar to the frame structure in NR and is used to determine the distribution position of the first time segment in the time domain. By determining the first time segment through the time-domain pattern, the accuracy and controllability of the transmission of the first signal by network devices and the monitoring of the first signal by terminal devices can be effectively improved, further optimizing overall energy saving.

[0052] In some embodiments, the time domain pattern includes a first time domain pattern, which is used to indicate the distribution of resource locations of the first resource in the time domain, and the first time segment is a time segment corresponding to the first resource. In other words, the time segment corresponding to the first resource is the first time segment that the embodiment of the present application should clarify, 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 segment in the time domain can be determined by the first time domain pattern, thereby further optimizing the technical proposal of the embodiment of the present application.

[0053] In some embodiments, the first resource is a resource from which a network device transmits a first signal. In other words, the network device transmits a first signal on a first resource. The embodiment of the present invention further clarifies the correlation between the first signal and the first resource, thereby improving the accuracy of the technical proposal of the embodiment of the present invention.

[0054] In some embodiments, the first resource is a resource corresponding to the first mode. In other words, a first mode may be set for terminal devices and / or network devices in the system, and the first resource may be a resource that has been set to the first mode in advance. The embodiment of the present application can further clarify the correlation between the operating mode of the device and the first resource and improve the accuracy of the technical proposal of the embodiment of the present application.

[0055] In some embodiments, the first mode is a mode in which network equipment transmits a first signal, and / or the first mode is a mode in which terminal equipment receives a first signal. In the above embodiment, the network device in the system may have a first mode, and the network device may transmit a first signal in that first mode. Alternatively, the terminal device in the system may have a first mode, and the terminal device may receive a first signal in that first mode. Alternatively, the network device and the terminal device in the system may both have a first mode, and the network device and the terminal device may both transmit and receive this first signal in that first mode. In other words, in the embodiments of the present application, the operating mode in which a network device transmits a first signal and / or the operating mode in which a terminal device receives a first signal can be defined as the first mode. The embodiments of the present application can further clarify the specific operating methods of the network device and terminal device in the first mode and improve the accuracy of the technical proposal of the embodiments of the present application.

[0056] In step 602, the network device transmits the second signal within the second time segment corresponding to the second resource. In response, the terminal device receives the second signal by its second receiver within the second time segment corresponding to the second resource. Here, the time-domain pattern further includes a second time-domain pattern, which is used to indicate the distribution of resource locations of the second resource in the time domain. In other words, the time domain pattern may include a first time domain pattern and a second time domain pattern. Correspondingly, the time segment corresponding to the second resource is the second time segment that the embodiment of the present application should clarify, 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 segment in the time domain can be determined by the second time domain pattern, and the technical proposal of the embodiment of the present application can be further optimized.

[0057] In other words, within a second time segment determined by the time-domain pattern, the network device transmits a second signal to the terminal device, and the terminal device receives the second signal via a second receiver. In some embodiments, the first time-domain pattern and the second time-domain pattern described above may be two independent time-domain patterns. Alternatively, the first time-domain pattern and the second time-domain pattern described above may be the same time-domain pattern, meaning that the time-domain pattern can also indicate the distribution of resources corresponding to two different signals in the time domain.

[0058] In some embodiments, the second signal includes a downlink signal used for paging. In other words, the second signal may be a downlink signal used for paging, meaning that terminal equipment UEs may be paged using a signal other than the first signal. For example, the UE may be paged using a legacy paging mechanism (i.e., direct transmission of Paging PDCCH), or paging may be pre-instructed by PEI.

[0059] In some embodiments, the second resource is the resource to which the network device transmits the second signal. In other words, the network device transmits a second signal on a second resource. The embodiment of the present invention can further clarify the correlation between the second signal and the second resource and improve the accuracy of the technical proposal of the embodiment of the present invention.

[0060] In some embodiments, the second resource is a resource corresponding to the second mode. In other words, a second mode can be set for terminal devices and / or network devices in the system, and the second resource may be a resource that has been pre-configured to the second mode. The embodiment of the present application can further clarify the correlation between the operating mode of the device and the second resource, and improve the accuracy of the technical proposal of the embodiment of the present application.

[0061] In some embodiments, the second mode is a mode in which network equipment transmits a second signal, and / or the second mode is a mode in which terminal equipment receives a second signal. In the above embodiment, the network device in the system may have a second mode, and the network device may transmit a second signal in that second mode. Alternatively, the terminal device in the system may have a second mode, and the terminal device may receive a second signal in that second mode. Alternatively, both the network device and the terminal device in the system may have a second mode, and the network device and the terminal device may transmit and receive this second signal in that second mode. In other words, the second mode can be defined as the operating mode in which network equipment transmits a second signal and / or the operating mode in which terminal equipment receives a second signal. The embodiments of the present application can further clarify the specific operating methods of network equipment and terminal equipment in the second mode and improve the accuracy of the technical proposal of the embodiments of the present application.

[0062] In some embodiments, the time-domain pattern is predefined by the protocol, or the time-domain pattern is semi-statically configured by the network equipment, or the time-domain pattern is dynamically configured by the network equipment, or the time-domain pattern is semi-statically configured and dynamically configured by the network equipment. In other words, the definition or setting of time-domain patterns can be flexibly selected according to actual needs, thereby effectively improving the flexibility and practicality of the proposed technology. For example, one or more time-domain patterns may be predefined by a protocol, one or more time-domain patterns may be semi-statically configured by network equipment, one or more time-domain patterns may be dynamically configured by network equipment, or multiple time-domain patterns may be semi-statically configured by network equipment, and then one or more time-domain patterns among the above multiple time-domain patterns may be dynamically configured / activated by network equipment.

[0063] The first signal may be a low-power wake-up signal LP-WUS, and the first receiver may be a low-power wake-up receiver LP-WUR. The second receiver may be a main receiver MR, and the second signal may be a paging signal such as Paging PDCCH.

[0064] If network equipment can support terminal equipment UEs including a low-power wake-up receiver LP-WUR, it is not always necessary to wake up the terminal equipment UE by waking up the main receiver MR with a low-power wake-up signal LP-WUS. Instead, a legacy mechanism, namely Paging PDCCH, can be directly transmitted to paging the main receiver MR of the terminal equipment UE, or Paging can be pre-instructed via PEI. Therefore, the time-domain pattern can determine whether the main receiver MR of the terminal equipment UE needs to be woken up with a low-power wake-up signal LP-WUS, meaning that switching between the first and second modes becomes possible, resulting in energy savings for the terminal equipment UE.

[0065] The first mode may be a mode in which network equipment wakes up terminal equipment UE with a low-power wake-up signal LP-WUS. In this mode, terminal equipment UE may continuously monitor LP-WUS or monitor LP-WUS in a duty cycle manner. That is, the first mode includes at least two paging cycles and at least two LP-WUS monitoring timings.

[0066] The second mode may be a mode in which network equipment wakes up terminal equipment UE by a non-LP-WUS. For example, this may be done by a legacy mechanism, i.e., by directly transmitting a Paging PDCCH to paging the main receiver MR of the terminal equipment UE, or by pre-instructing Paging by PEI.

[0067] With the above steps, the network device and the terminal device UE should each transmit and monitor LP-WUS on the time-domain resource corresponding to the first mode. On the time-domain resource corresponding to the second mode, the network device does not transmit 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 transmitted by the network device using the main receiver MR, and the terminal device UE does not monitor LP-WUS.

[0068] In some embodiments, time-domain patterns can be used to determine the pattern distributions of the first and second modes within a continuous time T that are periodically distributed in the time domain. Here, within a continuous time T, there is at least one first mode and at least one second mode.

[0069] Figure 7 shows a schematic diagram of a switching method that determines different modes based on a time-domain pattern. Within a continuous time T in the time domain, there is one first mode and one second mode, and the continuous time T is periodically distributed in the time domain.

[0070] Figure 8 shows a schematic diagram of another switching method that determines different modes based on a time-domain pattern. Within a continuous time T in the time domain, there are sequentially one first mode, two second modes, one first mode, and one second mode.

[0071] In some embodiments, the distribution of the first and second modes in the time domain may be constant as follows: This could be a single, fixed time-domain pattern design defined by the protocol, for example, where the time-domain ratio of the first mode to the second mode is 1:1. This could be a single time-domain pattern that is semi-statically configured by network equipment.

[0072] In some embodiments, the distribution of the first and second modes in the time domain may be flexibly set as follows: This may also be a time-domain pattern dynamically deployed by network devices. This may also be a time-domain pattern that is semi-statically placed by network devices.

[0073] In some embodiments, the time-domain distributions of the first and second modes may be multiple, as follows: This may be a set of multiple time-domain patterns defined by a protocol, or it may be a time-domain pattern that is dynamically or semi-statically configured and used by network equipment. These are multiple time-domain patterns that are semi-statically configured by network devices, or they may be time-domain patterns that are dynamically configured and used by network devices.

[0074] Based on the proposed technology shown in Figure 5 above, and referring to Figure 9, Figure 9 shows a flowchart of a method for receiving and transmitting a wake-up signal provided by one embodiment of the present invention. This method can be performed by interaction between a terminal device and a network device. Here, the terminal device may be terminal device 120 or terminal device 130 in the network architecture shown in Figure 1, and the network device may be network device 110 in the network architecture shown in Figure 1. This method may include the following steps.

[0075] In step 901, within the first time segment, the network device transmits a first signal. In response, within the first time segment, the terminal device receives the first signal by its first receiver, which is used to wake up the terminal device's second receiver. This first time segment is associated with the third time segment, which is the time segment in which the terminal device receives a third signal by its second receiver. In other words, within the first time segment associated with the third time segment, the network device transmits a first signal to the terminal device, the terminal device receives the first signal via a first receiver, and this first signal is used to wake up the terminal device's second receiver. The third time segment described above corresponds to the time segment in which the terminal device receives the third signal by the second receiver. Within the third time segment, the network device stops transmitting the first signal to the terminal device, and the terminal device stops receiving the first signal via the first receiver. By turning on the second receiver to monitor the wake-up signal, the accuracy and controllability of the transmission of the first signal by the network device and the monitoring of the first signal by the terminal device are effectively improved, and the energy-saving effect of the terminal device can be further optimized.

[0076] In some embodiments, the end of the first time segment described above is associated with the start of the third time segment. The technical solution shown in the embodiment of the present application provides a method for determining the first time segment by relating the end of the first time segment to the start of the third time segment.

[0077] In some embodiments, the start of the current first time segment is associated with the end of the previous third time segment, and correspondingly, the end of the current third time segment is associated with the start of the next first time segment. The association method may be the same, or there may be a constant offset between the two time points.

[0078] In some examples, the end of the first time segment is the same as the start of the third time segment, or there is a first offset between the end of the first time segment and the start of the third time segment.

[0079] The embodiment of the present application provides a specific method for associating the end time of the first time segment with the start time of the third time segment. In other words, the association between the end time of the first time segment and the start time of the third time segment may be such that the end time of the first time segment is the same as the start time of the third time segment, or the end time of the first time segment may be offset from the start time of the third time segment by a certain amount of time. For example, the end of the first time segment is the start of the third time segment. Alternatively, there is a certain time offset between the end of the first time segment and the start of the third time segment. Or, the sum of the time lengths of the forward or backward offsets from the end of the first time segment equals the third time segment.

[0080] In some embodiments, the start time of the first time segment is associated with the end time of the third time segment.

[0081] The technical solution shown in the embodiment of the present application provides a method for determining the first time segment by the third time segment, by associating the start time of the first time segment with the end time of the third time segment.

[0082] Furthermore, the end of the current first time segment is associated with the start of the previous third time segment. Correspondingly, the start of the current third time segment is associated with the end of the next first time segment. The association method may be the same, or there may be a certain offset between the two time points.

[0083] In some examples, the start time of the first time segment is the same as the end time of the third time segment, or there is a second offset between the start time of the first time segment and the end time of the third time segment. The embodiment of the present application provides a specific method for associating the end time of the first time segment with the start time of the third time segment. In other words, the association between the start time of the first time segment and the end time of the third time segment may be such that the start time of the first time segment is the same as the end time of the third time segment, or the start time of the first time segment may be offset from the end time of the third time segment by a certain amount of time. For example, the start of the first time segment is the end of the third time segment. Alternatively, there is a fixed time offset between the start of the first time segment and the end of the third time segment. Or, the sum of the forward or backward offsets from the start of the first time segment equals the third time segment.

[0084] In some embodiments, the third signal includes a downlink signal used for measurement and / or a downlink signal used for synchronization. In other words, the third signal may be a downlink signal used for measurement, a downlink signal used for synchronization, or may include both a downlink signal used for measurement and a downlink signal used for synchronization. In this embodiment, a downlink signal used for measurement and / or synchronization is selected as the third signal. By associating the time segments of reception and transmission of the first signal with the time segments of reception and transmission of the downlink signal used for measurement and / or synchronization, it is possible to avoid overlapping time-domain resources between the first signal and the measurement and / or synchronization downlink signal, thereby improving resource utilization.

[0085] In some embodiments, the third time segment is predefined by the protocol, or the third time segment is semi-statically configured by network equipment, or the third time segment is dynamically configured by network equipment, or the third time segment is semi-statically configured and dynamically configured by network equipment. In other words, the third time segment may be defined by a protocol or configured by network equipment (e.g., semi-static and / or dynamic configuration). The definition or configuration of the third time segment can be flexibly selected according to actual needs, thereby improving the flexibility and practicality of the proposed technology.

[0086] In some embodiments, the third time segment includes one or more slots, one or more frames, or one or more intermittent reception periods. In other words, the third time segment may be a slot where the third signal is located, a frame where the third signal is located, a single DRXcycle where the third signal is located, or x slots / frames / DRXcycles where the third signal is located, and can be flexibly selected according to actual needs, thereby effectively improving the flexibility and practicality of the proposed technology.

[0087] Here, 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, the second receiver may be a main receiver MR, and the third signal is a downlink signal on which the MR performs measurement and / or time-frequency synchronization. Due to the implementation method of LP-WUR and its relatively low sensitivity, performing measurement and time-frequency synchronization with LP-WUR alone is extremely difficult. Therefore, the only feasible implementation is for both LP-WUR and MR to perform measurement and time-frequency synchronization, meaning that MR requires measurement relaxation processing. Terminal equipment needs to turn on MR to perform measurement and time-frequency synchronization. At this time, regardless of whether or not LP-WUS is used to wake up MR, MR must be turned on to monitor the downlink signal. Against this backdrop, it is possible to decide whether or not to monitor LP-WUS based on the measurement operation of MR.

[0088] Figure 10 shows a schematic diagram of monitoring for LP-WUS based on MR measurement / synchronization decisions. In the first time unit when MR performs measurement and / or time-frequency synchronization, monitoring of LP-WUS by LP-WUR is stopped, and MR is turned on to monitor the wake-up signal. In time units when MR does not need to perform measurement and / or time-frequency synchronization, LP-WUR monitors LP-WUS.

[0089] When an LP-WUS signal is transmitted to the UE or the terminal group on which the UE is located, the MR is woken up and monitors the paging signal transmitted from the network equipment. While the LP-WUR wakes up the MR equipment and the MR equipment is monitoring the downlink signal, the LP-WUR may continue to monitor the LP-WUS or may stop monitoring the LP-WUS. Here, the first time unit may be a slot or frame in which measurement and / or time-frequency synchronization is performed, or one DRXcycle, or x slots / frames / DRXcycles. The first time unit may be defined by a protocol or set by network equipment (e.g., semi-static and / or dynamic settings).

[0090] In some embodiments, based on the technical proposal of step 901 above, within the fourth time segment, the network device does not perform the operation of transmitting the first signal, but rather transmits a downlink signal used for paging to the terminal device, which is received by the second receiver. Correspondingly, the terminal device does not perform the operation of receiving the first signal by the first receiver, but rather the terminal device can receive the downlink signal used for paging transmitted by the network device by the second receiver.

[0091] The fourth time segment is the time segment in which the second receiver receives the downlink signal used for paging.

[0092] In other words, the time segment in which the second receiver receives the downlink signal used for paging is defined as the fourth time segment, and within the third and fourth time segments, the network equipment stops transmitting the first signal to the terminal equipment, and the terminal equipment stops receiving the first signal by the first receiver. The second receiver may be turned on to monitor the wake-up signal.

[0093] The third time segment described above corresponds to the time segment in which the terminal device receives the third signal by the second receiver, and the fourth time segment described above corresponds to the time segment in which the second receiver receives the downlink signal used for paging.

[0094] By further restricting the timing of monitoring of the first signal by terminal equipment through the third and fourth time segments, the accuracy and controllability of the transmission of the first signal by network equipment and monitoring of the first signal by terminal equipment are effectively improved, thereby further optimizing the energy-saving effect of terminal equipment.

[0095] In other embodiments, the network device may perform an operation to transmit a first signal within a fourth time segment, and accordingly, the terminal device may also perform an operation to receive the first signal by a first receiver within a fourth time segment.

[0096] In some embodiments, the start of the fourth time segment is the same as the end of the third time segment, or there is a third offset between the start of the fourth time segment and the end of the third time segment.

[0097] The embodiments of this application are used to further illustrate the correlation between the fourth time segment and the third time segment. The start time of the fourth time segment may be the same as the end time of the third time segment. A third offset amount may exist between the start of the fourth time segment and the end of the third time segment.

[0098] If a fourth time segment exists, the start time of the current first time segment is associated with the end time of the previous fourth time segment. Correspondingly, the end time of the current fourth time segment is associated with the start time of the next first time segment. The association method may be the same, or there may be a certain offset between the two time points. Furthermore, the above-mentioned third offset amount may be the offset of the start point of the fourth time segment relative to the end point of the third time segment, or the fourth time segment may be a time segment corresponding to a certain length of time offset backward from the end point of the third time segment. For example, the end of the third time segment is the start of the fourth time segment. Alternatively, there is a fixed time offset between the end of the third time segment and the start of the fourth time segment. Or, the sum of the time offsets forward or backward from the end of the third time segment equals the fourth time segment.

[0099] In some embodiments, the fourth time segment includes one or more slots, or one or more frames, or one or more intermittent reception periods. In other words, the fourth time segment may be a slot or frame of the downlink signal used for paging, or one DRXcycle, or x slots / frames / DRXcycles. This flexibility in selection according to actual needs enhances the flexibility and practicality of the proposed technology.

[0100] In some embodiments, the fourth time segment is predefined by the protocol, or the fourth time segment is semi-statically configured by network equipment, or the fourth time segment is dynamically configured by network equipment, or the fourth time segment is semi-statically configured and dynamically configured by network equipment. In other words, the fourth time segment may be defined by a protocol or configured by network equipment (e.g., semi-static and / or dynamic configuration). The definition or configuration of the fourth time segment can be flexibly selected according to actual needs, thereby improving the flexibility and practicality of the proposed technology.

[0101] Furthermore, whether the above fourth time segment is defined by a protocol or set by a network may refer to whether the time-domain offset amount and / or time length of the fourth time segment relative to the third time segment is defined by a protocol or set by a network. Also, whether the fourth time segment is defined by a protocol or set by a network may refer to whether the time-domain position and / or time length of the starting point of the fourth time segment is defined by a protocol or set by a network.

[0102] Here, 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, the second receiver may be a main receiver MR, and the third signal is a downlink signal on which the MR performs measurement and / or time-frequency synchronization.

[0103] Figure 11 shows a schematic diagram of how monitoring for LP-WUS is determined based on MR measurement / synchronization / paging.

[0104] 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 in which the MR has performed measurement and / or time-frequency synchronization, the LP-WUR ceases monitoring of LP-WUS and turns on the MR 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-WUR monitors LP-WUS, and when an LP-WUS signal transmitted to the UE or the terminal group on which the UE is located is monitored, the MR wakes up and monitors the paging transmitted by the network equipment. While the LP-WUR wakes up the MR equipment and the MR equipment is monitoring the downlink signal, the LP-WUR may continue to monitor LP-WUS or may stop monitoring LP-WUS.

[0105] Here, the first time unit may be a slot or frame or one DRXcycle or x slots / frames / DRXcycles on which measurement and / or time-frequency synchronization is performed. The first time unit may be defined by a protocol or set by network equipment (e.g., semi-static and / or dynamic settings).

[0106] Here, the second time unit may or may not be equal to the first time unit, or it may be implemented based on a delay timer. The second time unit may be x slots / frames / DRX cycles, etc. The second time unit may be a time offset based on the first time unit. The second time unit may be defined by the protocol or set by network equipment (e.g., semi-static and / or dynamic settings).

[0107] Based on the proposed technology shown in Figure 5 above, and referring to Figure 12, Figure 12 shows a flowchart of a method for receiving and transmitting a wake-up signal provided by one embodiment of the present invention. This method can be performed by interaction between a terminal device and a network device. Here, the terminal device may be terminal device 120 or terminal device 130 in the network architecture shown in Figure 1, and the network device may be network device 110 in the network architecture shown in Figure 1. This method may include the following steps.

[0108] In step 1201, within the first time segment, a network device transmits a first signal. In response, within the first time segment, a terminal device receives the first signal with its first receiver, and this first signal is used to wake up the terminal device's second receiver. This first time segment is determined by periodic information, which is used to indicate the first period in which the first signal is received. In other words, within a first time segment determined by periodic information, network equipment transmits a first signal to terminal equipment, terminal equipment receives the first signal via a first receiver, this first signal is used to wake up the terminal equipment's second receiver, and this periodic information is used to indicate the first period in which the first signal is received. The periodic information determines the first time segment, and this periodic information can be used to indicate the first period in which the first signal is received. When in the first period in which the first signal is received, network equipment may transmit the first signal, and terminal equipment may receive the first signal with its first receiver. Conversely, network equipment stops transmitting the first signal, and terminal equipment stops receiving the first signal with its first receiver. This improves the accuracy and controllability of the transmission of the first signal by network equipment and the monitoring of the first signal by terminal equipment, further optimizing the energy-saving effect of terminal equipment.

[0109] In some embodiments, a first cycle comprises one or more active duration segments and one or more inactive segments. Sustain It includes time segments, and the first time segment is associated with the active duration segment. In other words, the first cycle consists of one active duration segment and one inactive segment. Sustain There may be time segments, or one active duration segment and multiple inactive segments. Sustain There may be time segments, or multiple active duration segments and one inactive segment. Sustain There may be time segments, or multiple active duration segments and multiple inactive segments. Sustain Time segments may also be included. The combination of time segments within one of the first cycles described above can be flexibly set according to actual needs, improving the flexibility and practicality of the present invention.

[0110] Here, the first hour segment is associated with the active duration segment.

[0111] In some embodiments, the first time segment includes an active duration segment. The embodiments of this application are used to illustrate a specific method of associating a first time segment with an active duration segment, namely, the first time segment includes at least one active duration segment. Here, if the above-mentioned first time segment includes an active duration segment, this first time segment is a general concept that encompasses multiple time segments, with each time segment corresponding to one active duration segment in the first cycle. In other words, the above-mentioned first time segment is a general term for time segments of the type known as active duration segments in the first cycle. For example, if the first cycle includes two active duration segments, and the terminal device needs to receive the first signal within multiple first cycles, then the first time segment mentioned above refers collectively to each active duration segment within the multiple first cycles.

[0112] In some embodiments, the time length of the first cycle, the time length of the active duration segment, and the inactive duration segment are defined as follows: Sustain At least one of the time segments is predefined by the protocol, or is the time length of the first period, the time length of the active duration segment, and the inactive duration segment. Sustain At least one of the time segments is semi-statically set by the network equipment, or it is the time length of the first cycle, the time length of the active duration segment, and the inactive duration segment. Sustain At least one of the time segments is dynamically set by the network device, or it is the time length of the first cycle, the time length of the active duration segment, and the inactive duration segment. Sustain At least one of the time segments' durations is set semi-statically and dynamically by the network equipment. In other words, the duration of the first cycle, the duration of the active duration segment, and the duration of the inactive period. Sustain The definition or setting of the time segment length may be specified by the protocol or set by network equipment (e.g., semi-static and / or dynamic settings), and can be flexibly selected according to actual needs, thereby improving the flexibility and practicality of the proposed technology.

[0113] In some embodiments, the first cycle is associated with the second cycle in which the second receiver performs measurements. In other words, the first period and the second period, in which the second receiver performs measurements, are related. Embodiments of the present application are used to illustrate the correlation between the first and second periods. As described above, one first period contains one or more active duration segments and one or more inactive segments. Sustain This includes time segments. Therefore, the association here is Inactive during the first cycle Sustain The time segment is associated with the time segment used for measurement in the second period, and / or, The active duration segment in the first cycle may be associated with a time segment that is not used for measurement in the second cycle.

[0114] In some embodiments, the time length of the first cycle, the time length of the active duration segment, and the inactive duration segment are defined as follows: Sustain At least one of the time segments is associated with the second cycle in which the second receiver performs the measurement.

[0115] The embodiments of this application are used to illustrate a specific method of associating the first period with the second period in which the second receiver performs measurements. The association here is based on time length, i.e., the time length of the first period, the time length of the active duration segment, and the inactive duration segment. Sustain At least one of the time segments may be associated with the second period in which the second receiver performs the measurement.

[0116] In some embodiments, the time length of the first period is an integer multiple of the time length of the second period, or the time length of the second period is an integer multiple of the time length of the first period.

[0117] The embodiments of this application are used to explain a specific method of relating the time length of the first period to the time length of the second period. The time lengths of the first and second periods may be integer multiples of each other. That is, the time length of the first period is an integer multiple of the time length of the second period. Alternatively, the time length of the second period is an integer multiple of the time length of the first period (or, it may be said that the time length of the first period is a factor of the time length of the second period). Specifically, for example, if the time length of the first cycle is 8 slots, the time length of the second cycle may be 1, 2, 4, 8, 16, 24 slots, etc.

[0118] In some embodiments, the duration of the active duration segment is an integer multiple of the duration of the time segment used for measurement in the second period. Alternatively, the duration of the time segment used for measurement in the second period is an integer multiple of the duration of the active duration segment.

[0119] The embodiments of this application are used to explain a specific method for relating the time length of the first period to the time length of the second period. The time length of the active duration segment and the time length of the time segment used for measurement in the second period may be integer multiples of each other. That is, the time length of the active duration segment is an integer multiple of the time length of the time segment used for measurement in the second period. Alternatively, the time length of the time segment used for measurement in the second period is an integer multiple of the time length of the active duration segment. Specifically, for example, if the duration of the active duration segment is 8 slots, the duration of the time segment used for measurement in the second cycle may be 1 slot, 2 slots, 4 slots, 8 slots, 16 slots, 24 slots, etc.

[0120] In some embodiments, inactive Sustain The length of the time segment is an integer multiple of the length of the time segment not used in the measurement during the second period. Alternatively, the length of the time segment not used in the measurement during the second period is inactive. Sustain It is an integer multiple of the time segment length.

[0121] The embodiments of this application are used to explain a specific method for relating the time length of the first period to the time length of the second period. The time length of the inactive duration segment and the time length of the time segment not used for measurement in the second period may be integer multiples of each other. That is, the time length of the inactive duration segment is an integer multiple of the time length of the time segment not used for measurement in the second period. Alternatively, the time length of the time segment not used for measurement in the second period is an integer multiple of the time length of the inactive duration segment. Specifically, for example, if the duration of the inactive duration segment is 8 slots, the duration of the time segments not used for measurement in the second cycle may be 1, 2, 4, 8, 16, 24 slots, etc.

[0122] Here, 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.

[0123] LP-WUS transmission and reception may be distributed periodically over time. That is, network devices periodically transmit LP-WUS signals, and terminal devices periodically monitor LP-WUS signals. In other words, network devices and terminal devices periodically activate / deactivate the transmission and reception of LP-WUS signals.

[0124] Figure 13 shows a schematic diagram of how monitoring for LP-WUS is determined based on the LP-WUS active period. LP-WUS is activated / deactivated periodically over time. Specifically, LP-WUS is activated once every certain time period T. The active duration of LP-WUS is D, and within time period T, the deactivation duration A of LP-WUS is T- D It becomes equal to.

[0125] Here, the time period T may be defined by the protocol or set by the network equipment. The active duration D of the LP-WUS may be defined by the protocol or set by the network equipment. The inactive time A of the LP-WUS may be defined by the protocol or set by the network equipment.

[0126] Here, at least one of T, D, and A is associated with the MR measurement period. For example, the active period T of the LP-WUS may be equal to the MR measurement period, an integer multiple of the MR measurement period, or a factor of the MR measurement period.

[0127] Here, at least one of T, D, and A is configured by the network device.

[0128] During the active duration D of the LP-WUS, the network device transmits the LP-WUS to the terminal device, and the terminal device receives the LP-WUS via the LP-WUR. The LP-WUS is used to wake up the terminal device's main receiver MR. During the inactive duration A of the LP-WUS, the network device stops transmitting the LP-WUS to the terminal device, and the terminal device stops receiving the LP-WUS via the LP-WUR.

[0129] In other embodiments, based on the technical proposal shown in Figure 13 above, multiple LP-WUS active timings may exist within a time period T. In other words, there may be multiple distributions of LP-WUS active durations within a time period T.

[0130] Figure 14 shows a schematic diagram of determining monitoring for an LP-WUS based on the active period of another LP-WUS. Within a time period T, there are two LP-WUS active timings, meaning there are two distributions of LP-WUS active durations within a time period T.

[0131] During the active timing of the two LP-WUS signals, the network device transmits an LP-WUS to the terminal device, and the terminal device receives the LP-WUS via the LP-WUR. The LP-WUS is used to wake up the terminal device's main receiver MR. During the inactive timing of the two LP-WUS signals, the network device stops transmitting LP-WUS signals to the terminal device, and the terminal device stops receiving LP-WUS signals via the LP-WUR.
