[0048] It should be understood that in the description of the embodiments of the present application, the term "corresponding" may indicate a direct or indirect correspondence between the two, or an association relationship between the two, or a relationship between indication and being indicated, configuration and being configured, etc.

The present application does not limit the specific implementation method. For example, predefined can refer to information defined in a protocol.

[0050] In the embodiments of the present application, "protocol" may refer to a standard protocol in the field of communications, for example, it may include an LTE protocol, a NR protocol, and related protocols used in future communication systems, and this application does not limit this.

[0051] Next, we will introduce Discontinuous Reception (DRX):

[0052] To save power on terminal devices, relevant communication systems support the DRX mechanism, which uses a semi-static configuration to achieve discontinuous reception of signals in the time domain. When there is no data transmission, power consumption can be reduced by stopping PDCCH reception.

[0053] To configure DRX, a terminal device in the Radio Resource Control (RRC) connected state (RRC_CONNECTED) configures a DRX cycle. Figure 1 shows a schematic diagram of the discontinuous reception transmission mechanism provided by related technologies. A DRX cycle consists of an active period (Active Time) and an inactive period (Inactive Time). During the active period, the terminal device monitors and receives the PDCCH; during the inactive period, the terminal device does not receive the PDCCH to reduce power consumption.

[0054] Next, the wake-up signal is introduced:

[0055] In related technologies, the DRX mechanism can be used in conjunction with a wake-up signal, and the terminal device receives an indication of the wake-up signal before the DRX on time (DRX ON duration). As shown in Figure 1, when the terminal device has data transmission within a DRX cycle, the wake-up signal wakes up the terminal device to detect the PDCCH during the DRX on time; when the terminal device has no data transmission within a DRX cycle, the wake-up signal does not wake up the terminal device, and the terminal device does not need to detect the PDCCH during the DRX on time. Compared with related DRX mechanisms, when the terminal device has no data transmission, the terminal device can omit the PDCCH detection during the DRX on time, thereby achieving energy saving. The time before the DRX on time of the terminal device can be called the inactive time, and the DRX on time of the terminal device can be called the active time. The DRX wake-up signal uses a waveform and structure similar to that of the PDCCH.

[0056] Next, the receiver system is introduced:

[0057] 2 shows a schematic diagram of a receiver system 200 provided by the related art. The receiver system 200 includes a wake-up receiver (WUR) 210 and a main radio 220.

[0058] In some embodiments, the primary receiver 220 can be equivalently understood as a primary transceiver, or a primary air interface communication unit.

[0059] To further save power, WUR is introduced to receive wake-up signals. The wake-up receiver is characterized by extremely low cost, extremely low complexity, and extremely low power consumption. It mainly receives the wake-up signal through a method based on envelope detection. In other methods, the use of similar traditional receiver methods is not ruled out. In short, the power consumption level of the wake-up receiver is several orders of magnitude lower than that of the traditional sleep mode. Generally speaking, the power consumption of traditional receivers is greater than 100 milliwatts, while low-power receivers can be less than 1 milliwatt.

[0060] Therefore, the wake-up signal (Wake Up Signal, WUS) received by the wake-up receiver is different from the modulation method, waveform, etc. of the signal carried by the physical downlink control channel (Physical Downlink Control CHannel, PDCCH) defined in the relevant standards. The wake-up signal can be an envelope signal modulated by amplitude shift keying (ASK) of the carrier signal. The demodulation of the envelope signal can also be completed by driving a low-power circuit with the energy provided by the wireless radio frequency signal, so it can be passive. The wake-up receiver can also be actively powered by the terminal device. Regardless of the power supply method, the receiver greatly reduces power consumption compared to traditional receivers. For example, WUR can achieve power consumption of less than 1 milliwatt, which is much lower than the power consumption of tens to hundreds of milliwatts of the main receiver. The wake-up receiver can be combined with the terminal device as an additional module of the terminal device's receiver, or it can be used alone as a wake-up function module of a terminal device.

[0061] As shown in Figure 1, in the initial state, wakeup receiver 210 is awake and main receiver 220 is off. Wakeup receiver 210 receives a wakeup signal and determines whether to wake up main receiver 220 based on the wakeup signal. If so, the network device can send a wakeup signal to wakeup receiver 210, which then wakes up main receiver 220 upon receiving the wakeup signal. Otherwise, main receiver 220 remains off.

[0062] In some embodiments, when the wake-up signal is sent, it is used to indicate wake-up; when the wake-up signal is not sent, it is used to indicate not wake-up.

[0063] In some embodiments, when a wake-up signal carrying a wake-up indication is sent, it is used to indicate wake-up; when a wake-up signal carrying a non-wake-up indication is sent, it is used to indicate non-wake-up.

[0064] The WUR can be activated by the WUS at any time and receive a wake-up signal. For example, the WUS signal uses on-off keying (OOK) modulation. The principle of OOK modulation is to modulate the amplitude of the carrier signal to non-zero values ​​(1) and zero values ​​(0), corresponding to On and Off, respectively, to represent information bits. OOK is also known as binary amplitude shift keying (2-ASK). For example, bit 1 is modulated to On and bit 0 is modulated to Off.

[0065] FIG3 shows a schematic diagram of a communication system 100 provided by an exemplary embodiment of the present application. The communication system 100 includes a terminal device 110 and a network device 120 .

[0066] The terminal device 110 in this application is also called UE, access terminal, user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent, and user equipment. The terminals include, but are not limited to, handheld devices, wearable devices, vehicle-mounted devices, and Internet of Things devices, such as mobile phones, tablet computers, e-book readers, laptop computers, desktop computers, televisions, game consoles, mobile Internet devices (MIDs), augmented reality (AR) terminals, virtual reality (VR) terminals, and mixed reality (MR) terminals, wearable devices, handles, electronic tags, controllers, wireless terminals in industrial control, wireless terminals in self-driving, wireless terminals in remote medical care, wireless terminals in smart grids, wireless terminals in transportation safety, wireless terminals in smart cities, wireless terminals in smart homes, wireless terminals in remote medical surgery, cellular phones, cordless phones, session initiation protocol (SIP) phones, wireless local loops (WLANs), and wireless terminals in industrial control.

[0067] The network device 120 in the present application provides wireless communication functions, and the network device 120 includes but is not limited to: an evolved node B (eNB), a radio network controller (RNC), a node B (NB), a base station controller (BSC), a base transceiver station (BTS), a home base station (e.g., a home evolved node B, or a home node B, HNB), a baseband unit (BBU), an access point (AP) in a Wi-Fi system, a wireless relay node, a wireless backhaul node, a transmission point (TP) or a transmission and reception point (TRP), etc. It can also be a next generation node B (gNB) or a transmission point (TRP or TP) in a 5G mobile communication system, or one or a group of antenna panels (including multiple antenna panels) of a base station in a 5G system, or a network node constituting a gNB or a transmission point, such as a baseband unit (BBU) or a distributed unit (DPU). The invention relates to a base station (DU) in a B5G mobile communication system or a 6G mobile communication system, or a core network (CN), fronthaul, backhaul, radio access network (RAN), network slicing, or a service cell, primary cell (PCell), primary secondary cell (PSCell), special cell (SpCell), secondary cell (SCell), and neighboring cell of a terminal device.

[0068] The terminal device 110 and the network device 120 communicate with each other via some air interface technology, such as a Uu interface.

[0069] Exemplarily, there are two communication scenarios between the terminal device 110 and the network device 120: uplink communication scenario and downlink communication scenario. Uplink communication refers to the terminal device 110 sending a signal to the network device 120; downlink communication refers to the network device 120 sending a signal to the terminal device 110.

[0070] The technical solutions provided in the embodiments of the present application can be applied to various communication systems, such as: GSM system, CDMA system, WCDMA system, GPRS, LTE system, LTE-A system, LTE frequency division duplex (FDD) system, LTE time division duplex (TDD) system, UMTS, Worldwide Interoperability for Microwave Access (WiMAX) communication system, 5G mobile communication system, NR system, NR system evolution system, LTE-U system, NR-U system, NTN system, non-NTN system, WLAN, Wi-Fi, cellular Internet of Things system, cellular passive Internet of Things system, and can also be applied to subsequent evolution systems of 5G NR system, and can also be applied to B5G, 6G and subsequent evolution systems.

[0071] In some embodiments of the present application, "NR" may also be referred to as a 5G NR system or a 5G system. A 5G mobile communication system may include a non-standalone (NSA) and / or standalone (SA) network.

[0072] The technical solutions provided in the embodiments of the present application can also be applied to machine type communication (MTC), long term evolution technology for machine-to-machine communication (LTE-M), device-to-device (D2D) network, machine-to-machine (M2M) network, Internet of Things (IoT) network or other networks. Among them, the IoT network can include, for example, the Internet of Vehicles. Among them, the communication mode in the Internet of Vehicles system is collectively referred to as vehicle to other devices (Vehicle to X, V2X, X can represent anything), for example, the V2X can include: vehicle to vehicle (V2V) communication, vehicle to infrastructure (V2I) communication, vehicle to pedestrian communication (V2P) or vehicle to network (V2N) communication, etc.

[0073] For terminal devices that support the DRX mechanism, when there is no data transmission, blind detection of the PDCCH will be stopped, thereby reducing the power consumption of the terminal device. In related technologies, it is possible to achieve power saving by combining a wake-up signal mechanism and entering the DRX mechanism activation time when a wake-up signal is received. However, the power consumption of detecting this wake-up signal is still high, which conflicts with the idea of ​​reducing the power consumption of the terminal device. To this end, an embodiment of the present application provides a method for detecting at least one of the two wake-up signals.

[0074] FIG4 shows a flowchart of a method for detecting a wake-up signal provided by an exemplary embodiment of the present application. The method is executed by a terminal device and includes:

[0075] Step 410: Detect at least one of a first wake-up signal and a second wake-up signal.

[0076] In some embodiments, the detection energy consumption of the first wake-up signal is lower than the detection energy consumption of the second wake-up signal.

[0077] In some embodiments, the first wake-up signal and the second wake-up signal have at least one of the following differences: different waveforms, different configuration periods, different time domain positions, and different corresponding receivers.

[0078] In some embodiments, whether the first wake-up signal and the second wake-up signal are received is used to indicate whether to start DRX detection and paging detection. If the first wake-up signal or the second wake-up signal is received, it indicates that DRX detection and paging detection are started. If the first wake-up signal or the second wake-up signal is not received, it indicates that DRX detection and paging detection are not started.

[0079] In some embodiments, the first wake-up signal carries first wake-up indication information, and the second wake-up signal carries second wake-up indication information. The first wake-up indication information and the second wake-up indication information are used to indicate whether to start DRX detection and paging detection and the start time.

[0080] In some embodiments, the first wake-up signal is a signal having a first waveform, and the second wake-up signal is a signal having a second waveform;

[0081] The first waveform is obtained based on a single-carrier modulation scheme, and the second waveform is obtained based on a multi-carrier modulation scheme. Both the first and second waveforms are simple waveforms, and the modulation schemes used include amplitude modulation, frequency modulation, and phase modulation. Single-carrier modulation refers to a modulation technique that uses only one carrier within a fixed frequency band, while multi-carrier modulation refers to a modulation technique that uses multiple carriers within a fixed frequency band.

[0082] Figure 5 shows a schematic diagram of amplitude modulation provided by an exemplary embodiment of the present application. Exemplarily, the signal sequence corresponding to the first wake-up signal is 101010, and after modulating the unmodulated carrier based on this signal sequence, the waveform of the modulated carrier is obtained as shown in Figure 5.

[0083] In some embodiments, the first waveform includes at least one of an OOK waveform, a binary phase shift keying (BSK) waveform, an ASK waveform, and a frequency shift keying (FSK) waveform; and the second waveform includes an orthogonal frequency division multiplexing (OFDM) waveform.

[0084] In the related art, by using a second wake-up signal, the active time (Active Time) of the DRX mechanism is entered when the second wake-up signal is received, thereby saving power. The second wake-up signal has a PDCCH waveform and can be called a normal wake-up signal. Its detection energy consumption is relatively high, which will lead to increased working energy consumption of the terminal device. In the embodiment of the present application, further power saving can be achieved by using a first wake-up signal with lower detection energy consumption. By using the second wake-up signal, a larger communication area can be covered. By detecting at least one of the two wake-up signals in combination with specific scenarios, it is possible to adapt to different channel environments and flexibly save energy.

[0085] Figure 6 shows a schematic diagram of generating a first wake-up signal provided by an exemplary embodiment of the present application. In some embodiments, the first wake-up indication information is information carried by the first wake-up signal, and the first wake-up indication information is converted into a signal sequence of length K, where K is a positive integer greater than 1. The conversion method includes at least one of upsampling, spread spectrum, and sequence mapping. Optionally, in the method of converting the first wake-up indication information in a sequence mapping manner, the sequence includes at least one of a constant envelope zero autocorrelation (CAZAC) sequence, a pseudo-noise (PN) sequence, a Gold sequence, an M sequence, and a Hadamard sequence.

[0086] The converted signal sequence is subjected to a discrete Fourier transform (DFT) to form multiple subcarrier signals. For example, the converted signal sequence y(n) is subjected to a DFT to obtain x(1), x(2) and so on to x(n). The multiple subcarrier signals generate a first wake-up signal through an inverse fast Fourier transform (IFFT). The waveform of the first wake-up signal in the time domain is expressed as a first waveform 610. Optionally, the multiple subcarrier signals can also be multiplexed with other NR signals before performing IFFT. Optionally, instead of performing DFT and IFFT on the converted signal sequence, single-carrier amplitude modulation is directly performed to obtain the first wake-up signal.

[0087] Optionally, the first wake-up signal is obtained by OOK modulation. OOK modulation is a process of modulating a digital sequence into a wireless signal with an MC-OOK waveform.

[0088] In some embodiments, the modulation steps of the first wake-up signal are as follows:

[0089] Step 1: Obtain a first sequence corresponding to the first wake-up indication information.

[0090] In some embodiments, the first sequence is any one of the following: an original sequence that does not require encoding; an original sequence before encoding; an encoded sequence after encoding the original sequence; or an encoded sequence after performing at least one level of multi-level encoding on the original sequence.

[0091] In some embodiments, when the sequence length of the first sequence is not an integer multiple of M, the first sequence is preprocessed to obtain a second sequence whose sequence length is an integer multiple of M. M is the number of OOK symbols transmitted in a preset duration. The preset duration is determined by a basic time domain unit in a cellular communication system or a WiFi system. In some embodiments, the preset duration is t OFDM symbols, and t OFDM symbols can transmit M OOK symbols. M is the number of OOK symbols transmitted in t OFDM symbols. The value of t is a positive integer.

[0092] Step 2: Divide the first sequence to obtain at least one sequence segment.

[0093] In some embodiments, when the first sequence is preprocessed to obtain the second sequence, the second sequence is divided to obtain at least one sequence segment.

[0094] Step 3: Perform OOK modulation on each sequence segment to obtain the OOK symbol corresponding to each sequence segment.

[0095] In some embodiments, OOK modulation includes at least one of: upsampling / spreading / sequence mapping, time-frequency transformation, determination of subcarrier coefficients, and inverse time-frequency transformation.

[0096] Upsampling / spreading / sequence mapping involves repeating each information element of a signal K times, where K is a positive integer greater than 1. Taking spread spectrum processing as an example, assuming the first wake-up signal sequence corresponding to the first wake-up signal is {1, 0, 0, 1} and the spreading factor is K = 4, the spread spectrum sequence is {1, 1, 1, 1, 0, 0, 0, 0, 0, 0, 1, 1, 1, 1}.

[0097] Time-frequency transform, also known as DFT, refers to the process of transforming a sequence in the time domain into frequency domain data of several sampling points.

[0098] Determining subcarrier coefficients refers to the process of determining the coefficients of multiple subcarriers during transmission based on the frequency domain data of several sampling points. This is also the process of modulating the frequency domain data after time-frequency transformation onto multiple subcarriers.

[0099] Inverse time-frequency transform, also known as inverse discrete Fourier transform (IDFT), refers to the process of converting frequency domain data of several sampling points into time domain data of several sampling points.

[0100] Optionally, the OOK modulation process further includes at least one of phase randomization, symbol randomization, and additional cyclic prefix (CP) / guard interval (GI).

[0101] Phase randomization is the process of processing intermediate data using a phase randomization factor or phase randomization sequence. Intermediate data is generated during the OOK modulation process. Adding phase randomization to the OOK modulation process can flatten the spectrum energy, improving frequency selectivity and interference immunity.

[0102] Symbol randomization eliminates spectral lines in the power spectral density (PSD) after processing OOK symbols to meet the communication requirements of some communication systems (such as 802.11) that require spectral line elimination.

[0103] Additional CP / GI is achieved by increasing CP / GI symbol by symbol or overall to reduce or eliminate multipath interference received during OOK symbol transmission, thereby improving the reception quality of OOK symbols.

[0104] In some embodiments, the first wake-up signal carries identification (ID) information of the target terminal device. In the case where the first wake-up signal carries the ID information of the target terminal device, the target terminal device receives the first wake-up signal.

[0105] In some embodiments, the first wake-up signal carries group ID information of the target terminal device group. In the case where the first wake-up signal carries the group ID information of the target terminal device group, all or some of the terminal devices in the target terminal device group receive the first wake-up signal.

[0106] In some embodiments, the awakening of the terminal device is indicated by ID information or group ID information, or the awakening of the terminal device is indicated by mapping different ID information or group ID information into a bitmap.

[0107] In some embodiments, detecting at least one of the first wake-up signal and the second wake-up signal includes at least one of the following three methods:

[0108] Method 1: detecting at least one of the first wake-up signal and the second wake-up signal based on the measurement result of the measurement signal;

[0109] Method 2: Detect at least one of the first wake-up signal and the second wake-up signal based on the configured detection period;

[0110] Method three: detecting at least one of the first wake-up signal and the second wake-up signal based on the indication signaling sent by the network device.

[0111] Based on three different methods, at least one of the first wake-up signal and the second wake-up signal is detected in different situations to meet the needs of different communication scenarios.

[0112] Method 1: detecting at least one of the first wake-up signal and the second wake-up signal based on the measurement result of the measurement signal.

[0113] In some embodiments, at least one of a first wake-up signal and a second wake-up signal is detected based on a measurement result of a first measurement signal; or at least one of the first wake-up signal and the second wake-up signal is detected based on a measurement result of a second measurement signal; or at least one of the first wake-up signal and the second wake-up signal is detected based on a measurement result of the first measurement signal and the second measurement signal; wherein the first measurement signal is associated with the first wake-up signal and the second measurement signal is associated with the second wake-up signal. The first measurement signal and the second measurement signal are reference signals.

[0114] In some embodiments, the measurement results include signal quality, which is determined by the signal-to-noise ratio (SINR) or signal strength. SINR refers to the ratio of signal to noise, typically expressed in decibels (dB). A larger signal-to-noise ratio indicates less noise and better signal quality; a smaller signal-to-noise ratio indicates more noise and poorer signal quality. Signal strength refers to the strength or power level of the received signal, typically expressed in decibel milliwatts (dBm). A larger signal strength indicates high signal strength, while a smaller signal strength indicates low signal strength.

[0115] In some embodiments, the first measurement signal has a waveform similar to the waveform 610 in FIG6 , and the adopted signal sequence includes at least one of a CAZAC sequence, a PN sequence, a Gold sequence, an M sequence, and a Hadamard sequence.

[0116] In some embodiments, the second measurement signal includes at least one of the following: a synchronization signal block (SSB), a channel state information reference signal (CSI-RS), a transmit reference signal (TRS), and a phase tracking reference signal (PT-RS).

[0117] At least one of the first wake-up signal and the second wake-up signal is detected based on the measurement results of the first measurement signal and / or the second measurement signal. When the signal quality of the measurement signal is high, the corresponding wake-up signal is detected to improve the detection success rate.

[0118] In some embodiments, when the signal quality of the first measurement signal is greater than a first threshold, the first wake-up signal is detected; when the signal quality of the first measurement signal is less than the first threshold, the second wake-up signal is detected.

[0119] In some embodiments, when the signal quality of the second measurement signal is greater than a second threshold, the second wake-up signal is detected; when the signal quality of the second measurement signal is less than the second threshold, the first wake-up signal is detected.

[0120] In some embodiments, the first threshold and the second threshold are the same or different. When the first threshold and the second threshold are different, the difference between the first threshold and the second threshold is the first difference. When configuring the network device, the first threshold and the second threshold can be independently configured, or the first threshold and the first difference can be configured, or the second threshold and the first difference can be configured.

[0121] In some embodiments, when the signal quality of the first measurement signal is greater than a first threshold and the signal quality of the second measurement signal is greater than a second threshold, the first wake-up signal and the second wake-up signal are detected; when the signal quality of the first measurement signal is greater than the first threshold and the signal quality of the second measurement signal is less than the second threshold, the first wake-up signal is detected; when the signal quality of the first measurement signal is less than the first threshold and the signal quality of the second measurement signal is greater than the second threshold, the second wake-up signal is detected.

[0122] By comparing the signal quality of the measurement signal with different thresholds, the first wake-up signal and / or the second wake-up signal are selectively detected, thereby reducing detection energy consumption.

[0123] In some embodiments, if the signal quality of the first measurement signal is less than a first threshold and the signal quality of the second measurement signal is less than a second threshold, control channel detection is initiated; the control channel detection includes at least one of DRX detection and paging detection. In this case, the first wake-up signal and the second wake-up signal are no longer detected subsequently, that is, the wake-up signal mechanism is not used, and DRX detection is initiated according to the DRX cycle, and paging detection is initiated according to the paging occasion.

[0124] If the signal quality of the first measurement signal is less than the first threshold and the signal quality of the second measurement signal is less than the second threshold, this may indicate that the detection of the first and second measurement signals has failed. In this case, since the detection of the first and second wake-up signals is likely to have failed, the control channel detection is directly initiated without detecting the first and second wake-up signals. This reduces the power consumption of the terminal device compared to detecting the first and second wake-up signals before initiating control channel detection.

[0125] Method 2: Based on the configured detection period, detect at least one of the first wake-up signal and the second wake-up signal.

[0126] In some embodiments, the detection period includes a first period and a second period; the first wake-up signal is detected based on the first period; when the first wake-up signal is detected, the second wake-up signal is detected based on the second period; wherein the first period is associated with the first wake-up signal and the second period is associated with the second wake-up signal.

[0127] In some embodiments, the first cycle is greater than the second cycle; the first cycle includes a first time period, which is a time period for detecting the first wake-up signal; the second cycle includes a second time period, which is a time period for detecting the second wake-up signal.

[0128] Figure 7 shows a schematic diagram of a first cycle and a second cycle provided by an exemplary embodiment of the present application, wherein each first cycle includes a first time period, and each second cycle includes a second time period.

[0129] In some embodiments, when the first wake-up signal is detected in the i-th first cycle, the second wake-up signal is detected in the third time period within the (i+1)-th first cycle; wherein the third time period is the intersection time period of the first time period and the second time period, and i is a positive integer.

[0130] For example, when i=1, if the first awakening signal is detected in the first first cycle, the second awakening signal is detected in the third time period of the second first cycle. As shown in FIG7 , the second awakening signal is detected in two third time periods represented by black squares.

[0131] Since the second wake-up signal is not detected under normal circumstances, the second wake-up signal is detected only after the first wake-up signal is detected. This saves more power than always detecting the second wake-up signal and reduces the power consumption of the terminal device.

[0132] In some embodiments, the detection period includes a first period and a second period; the second wake-up signal is detected based on the second period; when the second wake-up signal is detected, the first wake-up signal is detected based on the first period; wherein the first period is associated with the first wake-up signal and the second period is associated with the second wake-up signal.

[0133] In some embodiments, the first cycle is smaller than the second cycle; the first cycle includes a first time period, which is a time period for detecting the first wake-up signal; the second cycle includes a second time period, which is a time period for detecting the second wake-up signal.

[0134] Fig. 8 shows a schematic diagram of a first cycle and a second cycle provided by an exemplary embodiment of the present application, wherein each first cycle includes a first time period, and each second cycle includes a second time period.

[0135] In some embodiments, when the second wake-up signal is detected in the i-th second cycle, the first wake-up signal is detected in a third time period within the (i+1)-th second cycle; wherein the third time period is the intersection time period of the first time period and the second time period, and i is a positive integer.

[0136] For example, when i=1, if the second awakening signal is detected in the first second cycle, the first awakening signal is detected in the third time period of the second second cycle. As shown in FIG8 , the first awakening signal is detected in the two third time periods indicated by black squares.

[0137] When the network device knows in advance that the arrival time of the downlink data is around time T1, but the specific arrival time is unknown, the network device sends a second wake-up signal, causing the terminal device to enter a shorter detection cycle. When the downlink data actually arrives, the terminal device is quickly awakened by the first wake-up signal to receive the downlink data. For example, if the arrival time of the downlink data is around 0:0:00, the second cycle is configured to be 5 seconds and the first cycle is 1 second. When the second wake-up signal is detected in the i-th second cycle, the first wake-up signal is detected in the third time period within the i+1-th second cycle, where i is a positive integer. Compared with constantly detecting the first and second wake-up signals, this method consumes less power and can transmit data immediately if there is data to be transmitted, reducing data latency.

[0138] Method three: detecting at least one of the first wake-up signal and the second wake-up signal based on the indication signaling sent by the network device.

[0139] In some embodiments, when the indication signaling is used to indicate detection of a first wake-up signal, the first wake-up signal is detected; when the indication signaling is used to indicate detection of a second wake-up signal, the second wake-up signal is detected; when the indication signaling is used to indicate detection of a first wake-up signal and a second wake-up signal, the first wake-up signal and the second wake-up signal are detected.

[0140] Detecting the wake-up signal according to the indication signaling does not require any other design and is simpler and easier to implement.

[0141] In some embodiments, before detecting at least one of the first wake-up signal and the second wake-up signal based on the indication signaling sent by the network device, it also includes: sending measurement results of the first measurement signal and / or the second measurement signal, and the measurement results are used to assist the network device in sending the indication signaling.

[0142] By sending the measurement result to the network device, the network device is helped to determine the indication signaling to send. For example, when the measurement result of the first measurement signal indicates that the signal quality of the first measurement signal is greater than a first threshold, the network device sends the first indication signaling, and the first indication signaling is used to instruct the terminal device to detect the first wake-up signal.

[0143] For another example, when the measurement result of the first measurement signal indicates that the signal quality of the first measurement signal is less than the first threshold, and the measurement result of the second measurement signal indicates that the signal quality of the second measurement signal is less than the second threshold, the network device sends a fourth indication signaling, and the fourth indication signaling is used to instruct the terminal device to start detection of the control channel.

[0144] By sending the measurement result of the measurement signal, the network device is assisted in sending the indication signaling, so that the network device can reasonably send the indication signaling based on the signal quality of the measurement signal, thereby reducing the situation where the network device sends indication signaling that is not in line with reality. For example, if the signal quality of the second measurement signal is less than the second threshold, the network device will not send the indication signaling for instructing the detection of the second wake-up signal.

[0145] To summarize, the method provided in this embodiment detects at least one of the first wake-up signal and the second wake-up signal; wherein, the detection energy consumption of the first wake-up signal is lower than the detection energy consumption of the second wake-up signal, and the use of the first wake-up signal with lower detection energy consumption reduces the power consumption of the terminal device; the use of the second wake-up signal with a wider coverage area ensures the communication range of the terminal device; the combination of the first wake-up signal and the second wake-up signal can flexibly respond to communication scenarios with different needs.

[0146] The method provided in this embodiment further detects at least one of the first wake-up signal and the second wake-up signal based on the measurement result of the measurement signal. Based on the relationship between the signal quality of the measurement signal and different thresholds, at least one of the first wake-up signal and the second wake-up signal is selected for detection, thereby reducing detection energy consumption and thus reducing power consumption of the terminal device.

[0147] The method provided in this embodiment further detects at least one of the first wake-up signal and the second wake-up signal based on a configured detection period. By detecting the first wake-up signal based on a longer period, and then detecting the second wake-up signal based on a shorter period when the first wake-up signal is detected, there is no need to continuously detect both wake-up signals, thereby reducing power consumption of the terminal device.

[0148] The method provided in this embodiment also detects at least one of the first wake-up signal and the second wake-up signal based on the indication signaling sent by the network device. Detecting the wake-up signal based on the indication signaling does not require other designs and is simpler and easier to implement.

[0149] FIG9 shows a flowchart of a method for detecting a wake-up signal provided by an exemplary embodiment of the present application. The method is executed by a network device and includes:

[0150] Step 910: Send at least one of a first wake-up signal and a second wake-up signal.

[0151] The energy consumption of detecting the first wake-up signal is lower than the energy consumption of detecting the second wake-up signal.

[0152] In some embodiments, the network device further sends a measurement signal, where the measurement signal is used by the terminal device to detect at least one of the first wake-up signal and the second wake-up signal based on a measurement result of the measurement signal.

[0153] In some embodiments, the measurement signal includes a first measurement signal and a second measurement signal;

[0154] The first measurement signal is associated with the first wake-up signal, and the second measurement signal is associated with the second wake-up signal.

[0158] The first period is associated with the first wake-up signal, and the second period is associated with the second wake-up signal.

[0159] In some embodiments, the first cycle is greater than the second cycle; the first cycle includes a first time period, which is a time period for the terminal device to detect the first wake-up signal; the second cycle includes a second time period, which is a time period for the terminal device to detect the second wake-up signal.

[0160] In some embodiments, the first cycle is smaller than the second cycle; the first cycle includes a first time period, which is a time period for the terminal device to detect a first wake-up signal; the second cycle includes a second time period, which is a time period for the terminal device to detect a second wake-up signal.

[0161] For specific details of the detection cycle, please refer to the terminal device side embodiment and will not be repeated here.

[0162] In some embodiments, the first wake-up signal and the second wake-up signal are sent when there is downlink data or a paging instruction to be sent.

[0163] In some embodiments, the network device further sends an indication signaling, where the indication signaling is used to instruct the terminal device to detect at least one of the first wake-up signal and the second wake-up signal.

[0164] In some embodiments, the indication signaling includes at least one of a first indication signaling, a second indication signaling, and a third indication signaling;

[0165] The first indication signaling is used to instruct the terminal device to detect a first wake-up signal;

[0166] The second indication signaling is used to instruct the terminal device to detect the second wake-up signal;

[0167] The third indication signaling is used to instruct the terminal device to detect the first wake-up signal and the second wake-up signal.

[0168] In some embodiments, before sending the indication signaling, the network device further sends a measurement signal and receives a measurement result of the measurement signal, where the measurement result of the measurement signal is the signal quality obtained by the terminal device measuring the measurement signal.

[0169] In some embodiments, the measurement results include signal quality, which is determined by SINR or signal strength. SINR refers to the ratio of signal to noise, typically expressed in decibels (dB). A larger signal-to-noise ratio indicates less noise and better signal quality; a smaller signal-to-noise ratio indicates more noise and poorer signal quality. Signal strength refers to the strength or power level of the received signal, typically expressed in decibel milliwatts (dBm). A larger signal strength indicates high signal strength, while a smaller signal strength indicates low signal strength.

[0170] In some embodiments, the first measurement signal has a waveform similar to the waveform 610 in FIG6 , and the adopted signal sequence includes at least one of a CAZAC sequence, a PN sequence, a Gold sequence, an M sequence, and a Hadamard sequence.

[0171] In some embodiments, the second measurement signal includes at least one of the following: SSB, CSI-RS, TRS, PT-RS.

[0172] In some embodiments, indication signaling is sent based on the measurement result of the measurement signal.

[0173] In some embodiments, sending indication signaling based on a measurement result of the measurement signal includes:

[0174] Sending an indication signaling based on the measurement result of the first measurement signal; or,

[0175] Sending an indication signaling based on the measurement result of the second measurement signal; or,

[0176] Sending indication signaling based on measurement results of the first measurement signal and the second measurement signal;

[0177] The first measurement signal is associated with the first wake-up signal, and the second measurement signal is associated with the second wake-up signal.

[0178] In some embodiments, the first measurement signal and the second measurement signal are both reference signals. If the signal quality of the first measurement signal is poor and the signal quality of the second measurement signal is good, then the indication signaling indicates detection of the second wake-up signal; if the signal quality of the second measurement signal is poor and the signal quality of the first measurement signal is good, then the indication signaling indicates detection of the first wake-up signal.

[0179] In some embodiments, when the signal quality of the first measurement signal is greater than a first threshold, a first indication signaling is sent, and the first indication signaling is used to instruct the terminal device to detect the first wake-up signal; when the signal quality of the first measurement signal is less than the first threshold, a second indication signaling is sent, and the second indication signaling is used to instruct the terminal device to detect the second wake-up signal.

[0180] In some embodiments, when the signal quality of the second measurement signal is greater than the second threshold, a second indication signaling is sent, and the second indication signaling is used to instruct the terminal device to detect the second wake-up signal; when the signal quality of the second measurement signal is less than the second threshold, a first indication signaling is sent, and the first indication signaling is used to instruct the terminal device to detect the first wake-up signal.

[0181] In some embodiments, the first threshold and the second threshold are the same or different. When the first threshold and the second threshold are different, the difference between the first threshold and the second threshold is the first difference. When configuring the network device, the first threshold and the second threshold can be independently configured, or the first threshold and the first difference can be configured, or the second threshold and the first difference can be configured.

[0182] In some embodiments, when the signal quality of the first measurement signal is greater than a first threshold and the signal quality of the second measurement signal is greater than a second threshold, a third indication signaling is sent, the third indication signaling being used to instruct the terminal device to detect the first wake-up signal and the second wake-up signal; when the signal quality of the first measurement signal is greater than the first threshold and the signal quality of the second measurement signal is less than the second threshold, a first indication signaling is sent, the first indication signaling being used to instruct the terminal device to detect the first wake-up signal; when the signal quality of the first measurement signal is less than the first threshold and the signal quality of the second measurement signal is greater than the second threshold, a second indication signaling is sent, the second indication signaling being used to instruct the terminal device to detect the second wake-up signal. When the signal quality of the first measurement signal is less than the first threshold and the signal quality of the second measurement signal is less than the second threshold, a fourth indication signaling is sent, the fourth indication signaling being used to instruct the terminal device to initiate control channel detection; wherein the control channel detection includes at least one of DRX detection and paging detection.

[0183] In some embodiments, failure to detect the signal quality of the first measurement signal is considered to be less than a first threshold, and failure to detect the signal quality of the second measurement signal is considered to be less than a second threshold.

[0184] According to the size relationship between the signal quality of the first measurement signal and different thresholds, and the size relationship between the signal quality of the second measurement signal and different thresholds, corresponding indication signaling is sent, thereby adapting to communication scenarios with different channel qualities and being more flexible and energy-saving.

[0185] In some embodiments, the first wake-up signal is sent when there is downlink data or a paging instruction to be sent.

[0186] In some embodiments, the second wake-up signal is sent when there is downlink data or a paging instruction to be sent.

[0187] In some embodiments, the first wake-up signal and the second wake-up signal are sent when there is downlink data or a paging instruction to be sent.

[0188] The first wake-up signal and / or the second wake-up signal are wake-up signals sent on demand and are not sent when there is no downlink data to be sent or a paging instruction.

[0189] In some embodiments, the first wake-up signal is a signal having a first waveform, and the second wake-up signal is a signal having a second waveform;

[0190] The first waveform is obtained based on a single-carrier modulation mode, and the second waveform is obtained based on a multi-carrier modulation mode.

[0191] In some embodiments, the first waveform includes at least one of an OOK waveform, a BSK waveform, an ASK waveform, and an FSK waveform; and the second waveform includes an OFDM waveform.

[0192] For specific details of the first waveform and the second waveform, please refer to the terminal device side embodiment and will not be repeated here.

[0193] In summary, the method provided in this embodiment enables a terminal device to detect at least one of a first wake-up signal and a second wake-up signal by sending at least one of the first wake-up signal and the second wake-up signal; wherein the detection energy consumption of the first wake-up signal is lower than the detection energy consumption of the second wake-up signal. By using the first wake-up signal with lower detection energy consumption, the terminal device can reduce power consumption; by using the second wake-up signal with a wider coverage area, the communication range can be guaranteed; and by combining the first and second wake-up signals, the terminal device can flexibly respond to communication scenarios with different requirements.

[0194] The method provided in this embodiment further transmits a measurement signal, which is used by the terminal device to detect at least one of the first wake-up signal and the second wake-up signal based on the measurement result of the measurement signal. The terminal device selects to detect at least one of the first wake-up signal and the second wake-up signal based on the relationship between the signal quality of the measurement signal and different thresholds, thereby reducing detection energy consumption and thus reducing power consumption of the terminal device.

[0195] The method provided in this embodiment further configures a detection period for the terminal device to detect at least one of the first wake-up signal and the second wake-up signal. The terminal device detects the first wake-up signal based on a longer period. Upon detecting the first wake-up signal, the terminal device detects the second wake-up signal based on a shorter period. This eliminates the need to continuously detect both wake-up signals, thereby reducing power consumption of the terminal device.

[0196] The method provided in this embodiment further includes sending indication signaling to instruct the terminal device to detect at least one of the first wake-up signal and the second wake-up signal. Detecting the wake-up signal based on the indication signaling does not require any additional design, making it simpler and easier to implement. Furthermore, by sending corresponding indication signaling based on the relationship between the signal quality of the first measurement signal and different thresholds, as well as the relationship between the signal quality of the second measurement signal and different thresholds, the method adapts to communication scenarios with varying channel qualities, providing greater flexibility and energy conservation.

[0197] In the above embodiments, the embodiment corresponding to Figure 4 and the embodiment corresponding to Figure 9 can be implemented separately or in combination, and this application does not limit this. Figure 10 shows a schematic diagram of a communication scenario provided by an exemplary embodiment of the present application.

[0198] In some embodiments, the first terminal device 111 and the third terminal device 113 are within the coverage range of the first measurement signal, and the second terminal device 112 is within the coverage range of the second measurement signal. Since the first measurement signal is associated with the first wake-up signal, and the second measurement signal is associated with the second wake-up signal, the coverage range of the first measurement signal is also the coverage range of the first wake-up signal, and the coverage range of the second measurement signal is also the coverage range of the second wake-up signal. The first terminal device 111 and the third terminal device 113 can detect the first wake-up signal (first measurement signal) and the second wake-up signal (second measurement signal), and the second terminal device 112 can only detect the second wake-up signal (second measurement signal).

[0199] In some embodiments, second terminal device 112 sends measurement results of the first measurement signal and the second measurement signal. Because the first measurement signal is not detected, it is deemed that the signal quality of the first measurement signal is less than a first threshold; and because the signal quality of the second measurement signal is greater than a second threshold, network device 120 sends second indication signaling, where the second indication signaling is used to instruct second terminal device 112 to detect the second wake-up signal.

[0200] In some embodiments, the second terminal device 112 only detects the second wake-up signal. To ensure that the second terminal device 112 can receive the paging in time, when only detecting the second wake-up signal, the network device configures a smaller second period for the second terminal device 112.

[0201] In some embodiments, first terminal device 111 sends measurement results of the first measurement signal and the second measurement signal. Because the signal quality of the first measurement signal is greater than the first threshold and the signal quality of the second measurement signal is greater than the second threshold, network device 120 sends third indication signaling, where the third indication signaling is used to instruct first terminal device 111 to detect the first wake-up signal and the second wake-up signal.

[0202] In some embodiments, the network device 120 configures a first period and a second period, the first period is greater than the second period, the first period includes a first time period, and the first time period is a time period for detecting a first wake-up signal; the second period includes a second time period, and the second time period is a time period for detecting a second wake-up signal.

[0203] Exemplarily, when the first terminal device 111 detects the first wake-up signal in the first first cycle, it detects the second wake-up signal in the third time period in the second first cycle; wherein the third time period is the intersection time period of the first time period and the second time period.

[0204] Since the second wake-up signal is not detected under normal circumstances, the second wake-up signal is detected only after the first wake-up signal is detected. This saves more power than always detecting the second wake-up signal and reduces the power consumption of the terminal device.

[0205] In some embodiments, the network device 120 configures a first period and a second period, the first period is smaller than the second period, the first period includes a first time period, and the first time period is a time period for detecting a first wake-up signal; the second period includes a second time period, and the second time period is a time period for detecting a second wake-up signal.

[0206] Exemplarily, when the first terminal device 111 detects the second wake-up signal in the first first cycle, it detects the first wake-up signal in the third time period in the second second cycle; wherein the third time period is the intersection time period of the first time period and the second time period.

[0207] When the network device 120 knows in advance that the arrival time of the downlink data is around time T1, but the specific arrival time is unknown, the network device 120 sends a second wake-up signal, causing the first terminal device 111 to enter a shorter detection cycle. When the downlink data actually arrives, the first terminal device 111 is quickly awakened by the first wake-up signal to receive the downlink data. For example, if the arrival time of the downlink data is around 0:0:00, the second cycle is configured to be 5 seconds and the first cycle is 1 second. When the second wake-up signal is detected in the i-th second cycle, the first wake-up signal is detected in the third time period within the i+1-th second cycle, where i is a positive integer. Compared with always detecting the first wake-up signal and the second wake-up signal, this method consumes less power and can transmit the data immediately when there is data to be transmitted, thereby reducing data latency.

[0208] In some embodiments, the third terminal device 113 interferes with the detection of the second measurement signal by the first terminal device 111, causing the signal quality of the second measurement signal to be less than a second threshold. The first terminal device 111 sends the measurement results of the first measurement signal and the second measurement signal. Because the signal quality of the first measurement signal is greater than the first threshold and the signal quality of the second measurement signal is less than the second threshold, the network device 120 sends a first indication signaling, where the first indication signaling is used to instruct the first terminal device 111 to detect the first wake-up signal.

[0209] In some embodiments, the first terminal device 111 only detects the first wake-up signal. To ensure that the first terminal device 111 can receive the paging in time, when only the first wake-up signal is detected, the network device configures a smaller first period for the first terminal device 111.

[0210] In summary, the network device 120 reasonably sends different wake-up signals in different scenarios based on the measurement results of the measurement signals sent by the terminal device, thereby reducing the power consumption of the terminal device.

[0211] FIG11 shows a block diagram of a wake-up signal detection apparatus provided by an exemplary embodiment of the present application. The apparatus can be implemented as a terminal device, or as a part of a terminal device, through software or hardware, or a combination of both. The apparatus includes:

[0212] The detection module 1110 is configured to detect at least one of a first wake-up signal and a second wake-up signal; wherein the energy consumption of detecting the first wake-up signal is lower than the energy consumption of detecting the second wake-up signal.

[0213] In a possible design of this embodiment, the first wake-up signal and the second wake-up signal have at least one of the following differences: different waveforms, different configuration periods, different time domain positions, and different corresponding receivers.

[0214] In one possible design of this embodiment, whether the first wake-up signal and the second wake-up signal are received is used to indicate whether to start DRX detection and paging detection. If the first wake-up signal or the second wake-up signal is received, it indicates that DRX detection and paging detection are started; if the first wake-up signal and the second wake-up signal are not received, it indicates that DRX detection and paging detection are not started.

[0215] In a possible design of this embodiment, the first wake-up signal carries first wake-up indication information, and the second wake-up signal carries second wake-up indication information. The first wake-up indication information and the second wake-up indication information are used to indicate whether to start DRX detection and paging detection and the start time.

[0216] In a possible design of this embodiment, the first wake-up signal is a signal having a first waveform, and the second wake-up signal is a signal having a second waveform;

[0217] The first waveform is obtained based on a single-carrier modulation scheme, and the second waveform is obtained based on a multi-carrier modulation scheme. Both the first and second waveforms are simple waveforms, and the modulation schemes used include amplitude modulation, frequency modulation, and phase modulation. Single-carrier modulation refers to a modulation technique that uses only one carrier within a fixed frequency band, while multi-carrier modulation refers to a modulation technique that uses multiple carriers within a fixed frequency band.

[0218] Figure 5 shows a schematic diagram of amplitude modulation provided by an exemplary embodiment of the present application. Exemplarily, the signal sequence corresponding to the first wake-up signal is 101010, and after modulating the unmodulated carrier based on this signal sequence, the waveform of the modulated carrier is obtained as shown in Figure 5.

[0219] In a possible design of this embodiment, the first waveform includes at least one of an OOK waveform, a binary phase shift keying (BSK) waveform, an ASK waveform, and a frequency shift keying (FSK) waveform; the second waveform includes an orthogonal frequency division multiplexing (OFDM) waveform.

[0220] In the related art, by using a second wake-up signal, the activation time (Active Time) of the DRX mechanism is entered when the second wake-up signal is received, thereby saving power. The second wake-up signal has a PDCCH waveform and can be called a normal wake-up signal. Its detection energy consumption is relatively high, which will lead to an increase in the working energy consumption of the detection device of the wake-up signal. In the embodiment of the present application, by using a first wake-up signal with lower detection energy consumption, further power saving can be achieved. By using the second wake-up signal, a larger communication area can be covered. By detecting at least one of the two wake-up signals in combination with specific scenarios, it is possible to adapt to different channel environments and save energy flexibly.

[0221] Figure 6 shows a schematic diagram of generating a first wake-up signal provided by an exemplary embodiment of the present application. In a possible design of this embodiment, the first wake-up indication information is information carried by the first wake-up signal, and the first wake-up indication information is converted into a signal sequence of length K, where K is a positive integer greater than 1. The conversion method includes at least one of upsampling, spread spectrum, and sequence mapping. Optionally, in the method of converting the first wake-up indication information in a sequence mapping manner, the sequence includes at least one of a constant envelope zero autocorrelation (CAZAC) sequence, a pseudo-noise (PN) sequence, a Gold sequence, an M sequence, and a Hadamard sequence.

[0222] The converted signal sequence is subjected to a discrete Fourier transform (DFT) to form multiple subcarrier signals. For example, the converted signal sequence y(n) is subjected to a DFT to obtain x(1), x(2) and so on to x(n). The multiple subcarrier signals generate a first wake-up signal through an inverse fast Fourier transform (IFFT). The waveform of the first wake-up signal in the time domain is expressed as a first waveform 610. Optionally, the multiple subcarrier signals can also be multiplexed with other NR signals before performing IFFT. Optionally, instead of performing DFT and IFFT on the converted signal sequence, single-carrier amplitude modulation is directly performed to obtain the first wake-up signal.

[0223] Optionally, the first wake-up signal is obtained by OOK modulation. OOK modulation is a process of modulating a digital sequence into a wireless signal with an MC-OOK waveform.

[0224] In one possible design of this embodiment, the first wake-up signal carries the ID information of the target wake-up signal detection device. In the case where the first wake-up signal carries the ID information of the target wake-up signal detection device, the target wake-up signal detection device receives the first wake-up signal.

[0225] In one possible design of this embodiment, the first wake-up signal carries the group ID information of the target wake-up signal detection device group. When the first wake-up signal carries the group ID information of the target wake-up signal detection device group, the first wake-up signal is received by all or some of the wake-up signal detection devices in the target wake-up signal detection device group.

[0226] In a possible design of this embodiment, the awakening of the awakening signal detection device is indicated by ID information or group ID information, or the awakening of the awakening signal detection device is indicated by mapping different ID information or group ID information into a bitmap.

[0227] In one possible design of this embodiment, the detection module 1110 is configured to use at least one of the following three detection methods:

[0228] Method 1: detecting at least one of the first wake-up signal and the second wake-up signal based on the measurement result of the measurement signal;

[0229] Method 2: Detect at least one of the first wake-up signal and the second wake-up signal based on the configured detection period;

[0230] Method three: detecting at least one of the first wake-up signal and the second wake-up signal based on the indication signaling sent by the wake-up signal sending device.

[0231] Method 1: detecting at least one of the first wake-up signal and the second wake-up signal based on the measurement result of the measurement signal.

[0232] In one possible design of this embodiment, detection module 1110 is configured to detect at least one of a first wake-up signal and a second wake-up signal based on a measurement result of a first measurement signal; or, based on a measurement result of a second measurement signal, detect at least one of the first wake-up signal and the second wake-up signal; or, based on the measurement results of the first measurement signal and the second measurement signal, detect at least one of the first wake-up signal and the second wake-up signal; wherein the first measurement signal is associated with the first wake-up signal, and the second measurement signal is associated with the second wake-up signal. The first measurement signal and the second measurement signal are reference signals.

[0233] In one possible design of this embodiment, the measurement result includes signal quality, and the signal quality is determined by the signal-to-noise ratio (SINR) or signal strength. SINR refers to the ratio of signal to noise, typically expressed in decibels (dB). A larger signal-to-noise ratio indicates less noise and better signal quality; a smaller signal-to-noise ratio indicates more noise and poorer signal quality. Signal strength refers to the strength or power level of the received signal, typically expressed in decibel milliwatts (dBm). A larger signal strength indicates high signal strength, and a smaller signal strength indicates low signal strength.

[0234] In a possible design of this embodiment, the waveform of the first measurement signal is similar to the waveform 610 in FIG6 , and the adopted signal sequence includes at least one of a CAZAC sequence, a PN sequence, a Gold sequence, an M sequence, and a Hadamard sequence.

[0235] In a possible design of this embodiment, the second measurement signal includes at least one of the following: a synchronization signal block (SSB), a channel state information reference signal (CSI-RS), a transmit reference signal (TRS), and a phase tracking reference signal (PT-RS).

[0236] At least one of the first wake-up signal and the second wake-up signal is detected based on the measurement results of the first measurement signal and / or the second measurement signal. When the signal quality of the measurement signal is high, the corresponding wake-up signal is detected to improve the detection success rate.

[0237] In a possible design of this embodiment, the detection module 1110 is used to detect a first wake-up signal when the signal quality of the first measurement signal is greater than a first threshold; and to detect a second wake-up signal when the signal quality of the first measurement signal is less than the first threshold.

[0238] In a possible design of this embodiment, the detection module 1110 is used to detect the second wake-up signal when the signal quality of the second measurement signal is greater than the second threshold; and to detect the first wake-up signal when the signal quality of the second measurement signal is less than the second threshold.

[0239] In a possible design of this embodiment, the detection module 1110 is used to detect the first wake-up signal and the second wake-up signal when the signal quality of the first measurement signal is greater than the first threshold and the signal quality of the second measurement signal is greater than the second threshold; detect the first wake-up signal when the signal quality of the first measurement signal is greater than the first threshold and the signal quality of the second measurement signal is less than the second threshold; detect the second wake-up signal when the signal quality of the first measurement signal is less than the first threshold and the signal quality of the second measurement signal is greater than the second threshold.

[0240] By comparing the signal quality of the measurement signal with different thresholds, the first wake-up signal and / or the second wake-up signal are selectively detected, thereby reducing detection energy consumption.

[0241] In one possible design of this embodiment, the detection module 1110 is further configured to initiate control channel detection when the signal quality of the first measurement signal is less than a first threshold and the signal quality of the second measurement signal is less than a second threshold; the control channel detection includes at least one of DRX detection and paging detection. In this case, the first wake-up signal and the second wake-up signal are no longer detected subsequently, that is, the wake-up signal mechanism is not used, and DRX detection is initiated according to the DRX cycle, and paging detection is initiated according to the paging occasion.

[0242] If the signal quality of the first measurement signal is less than the first threshold and the signal quality of the second measurement signal is less than the second threshold, this indicates that detection of the first and second measurement signals has failed. In this case, since detection of the first and second wake-up signals has likely failed, detection of the first and second wake-up signals is not performed, and control channel detection is initiated directly. This reduces power consumption of the wake-up signal detection device compared to detecting the first and second wake-up signals before initiating control channel detection.

[0243] Method 2: Based on the configured detection period, detect at least one of the first wake-up signal and the second wake-up signal.

[0244] In a possible design of this embodiment, the detection period includes a first period and a second period; the detection module 1110 is used to detect a first wake-up signal based on the first period; when the first wake-up signal is detected, the second wake-up signal is detected based on the second period; wherein the first period is associated with the first wake-up signal, and the second period is associated with the second wake-up signal.

[0245] In a possible design of this embodiment, the first cycle is greater than the second cycle; the first cycle includes a first time period, which is a time period for detecting a first wake-up signal; the second cycle includes a second time period, which is a time period for detecting a second wake-up signal.

[0246] Figure 7 shows a schematic diagram of a first cycle and a second cycle provided by an exemplary embodiment of the present application, wherein each first cycle includes a first time period, and each second cycle includes a second time period.

[0247] In a possible design of this embodiment, the detection module 1110 is used to detect a second wake-up signal in a third time period within the (i+1)th first cycle when a first wake-up signal is detected in the i-th first cycle; wherein the third time period is the intersection time period of the first time period and the second time period, and i is a positive integer.

[0248] For example, when i=1, if the first awakening signal is detected in the first first cycle, the second awakening signal is detected in the third time period of the second first cycle. As shown in FIG7 , the second awakening signal is detected in two third time periods represented by black squares.

[0249] Since the second wake-up signal is not detected in general, detecting the second wake-up signal after detecting the first wake-up signal saves more power than always detecting the second wake-up signal, thereby reducing the power consumption of the wake-up signal detection device.

[0250] In a possible design of this embodiment, the detection period includes a first period and a second period; the detection module 1110 is used to detect the second wake-up signal based on the second period; when the second wake-up signal is detected, the first wake-up signal is detected based on the first period; wherein the first period is associated with the first wake-up signal, and the second period is associated with the second wake-up signal.

[0251] In a possible design of this embodiment, the first cycle is smaller than the second cycle; the first cycle includes a first time period, which is a time period for detecting a first wake-up signal; the second cycle includes a second time period, which is a time period for detecting a second wake-up signal.

[0252] Fig. 8 shows a schematic diagram of a first cycle and a second cycle provided by an exemplary embodiment of the present application, wherein each first cycle includes a first time period, and each second cycle includes a second time period.

[0253] In a possible design of this embodiment, the detection module 1110 is used to detect the first wake-up signal in a third time period within the (i+1)th second cycle when the second wake-up signal is detected in the i-th second cycle; wherein the third time period is the intersection time period of the first time period and the second time period, and i is a positive integer.

[0254] For example, when i=1, if the second awakening signal is detected in the first second cycle, the first awakening signal is detected in the third time period of the second second cycle. As shown in FIG8 , the first awakening signal is detected in the two third time periods indicated by black squares.

[0255] When the wake-up signal transmitting device knows in advance that the arrival time of the downlink data is around time T1, but the specific arrival time is unknown, the wake-up signal transmitting device transmits a second wake-up signal, causing the wake-up signal detection device to enter a shorter detection cycle. When the downlink data actually arrives, the wake-up signal detection device is quickly awakened by the first wake-up signal to receive the downlink data. For example, if the arrival time of the downlink data is around 0:0:00, the second cycle is configured to be 5 seconds and the first cycle is 1 second. When the second wake-up signal is detected in the i-th second cycle, the first wake-up signal is detected in the third time period within the i+1-th second cycle, where i is a positive integer. Compared with constantly detecting the first and second wake-up signals, this reduces power consumption and, if there is data to be transmitted, enables immediate transmission of the data, reducing data latency.

[0256] Method three: detecting at least one of the first wake-up signal and the second wake-up signal based on the indication signaling sent by the wake-up signal sending device.

[0257] In a possible design of this embodiment, the detection module 1110 is used to detect the first wake-up signal when the indication signaling is used to indicate the detection of the first wake-up signal; detect the second wake-up signal when the indication signaling is used to indicate the detection of the second wake-up signal; and detect the first wake-up signal and the second wake-up signal when the indication signaling is used to indicate the detection of the first wake-up signal and the second wake-up signal.

[0258] Detecting the wake-up signal according to the indication signaling does not require any other design and is simpler and easier to implement.

[0259] In a possible design of this embodiment, the sending module 1120 is used to send measurement results of the first measurement signal and / or the second measurement signal, and the measurement results are used to assist the sending device of the wake-up signal to send indication signaling.

[0260] By sending the measurement result to the wake-up signal sending device, the wake-up signal sending device is helped to determine the indication signaling to send. For example, when the measurement result of the first measurement signal indicates that the signal quality of the first measurement signal is greater than a first threshold, the wake-up signal sending device sends the first indication signaling, and the first indication signaling is used to instruct the wake-up signal detection device to detect the first wake-up signal.

[0261] For another example, when the measurement result of the first measurement signal indicates that the signal quality of the first measurement signal is less than the first threshold, and the measurement result of the second measurement signal indicates that the signal quality of the second measurement signal is less than the second threshold, the wake-up signal sending device sends a fourth indication signaling, and the fourth indication signaling is used to instruct the wake-up signal detection device to start the detection of the control channel.

[0262] By sending the measurement result of the measurement signal, the wake-up signal sending device is assisted in sending the indication signaling, so that the wake-up signal sending device can reasonably send the indication signaling based on the signal quality of the measurement signal, thereby reducing the situation where the wake-up signal sending device sends indication signaling that does not conform to reality. For example, if the signal quality of the second measurement signal is less than the second threshold, the wake-up signal sending device will not send the indication signaling for instructing the detection of the second wake-up signal.

[0263] In this embodiment, the detection module 1110 can be divided into at least one detection submodule, each detection submodule is used to perform at least one of the above detection steps, such as a first detection submodule, a second detection submodule, and a third detection submodule. The first detection submodule is configured to detect at least one of the first wake-up signal and the second wake-up signal based on the measurement result of the measurement signal, the second detection submodule is configured to detect at least one of the first wake-up signal and the second wake-up signal based on a configured detection period, and the third detection submodule is configured to detect at least one of the first wake-up signal and the second wake-up signal based on an indication signaling sent by the wake-up signal sending device; or the first detection submodule is configured to detect at least one of the first wake-up signal and the second wake-up signal based on the configured detection period, the second detection submodule is configured to detect at least one of the first wake-up signal and the second wake-up signal based on an indication signaling sent by the wake-up signal sending device, and the third detection submodule is configured to detect at least one of the first wake-up signal and the second wake-up signal based on the measurement result of the measurement signal; or the first detection submodule is configured to detect at least one of the first wake-up signal and the second wake-up signal based on the indication signaling sent by the wake-up signal sending device, the second detection submodule is configured to detect at least one of the first wake-up signal and the second wake-up signal based on the measurement result of the measurement signal, and the third detection submodule is configured to detect at least one of the first wake-up signal and the second wake-up signal based on a configured detection period. This embodiment does not limit the functions of the different detection submodules.

[0264] This embodiment is described by taking one detection module 1110 as an example, and the number of detection modules 1110 is not limited.

[0266] For an introduction to the functions of the sending module 1120 , please refer to the content of step 410 in the embodiment of FIG. 4 .

[0267] FIG12 shows a block diagram of a device for sending a wake-up signal according to an exemplary embodiment of the present application. The device can be implemented as a network device or as part of a network device through software or hardware or a combination of both. The device includes:

[0268] The sending module 1210 is configured to send at least one of a first wake-up signal and a second wake-up signal; wherein the detection energy consumption of the first wake-up signal is lower than the detection energy consumption of the second wake-up signal.

[0269] In a possible design of this embodiment, the first wake-up signal and the second wake-up signal have at least one of the following differences: different waveforms, different configuration periods, different time domain positions, and different corresponding receivers.

[0270] In one possible design of this embodiment, whether the wake-up signal detection apparatus receives the first wake-up signal and the second wake-up signal is used to indicate whether the wake-up signal detection apparatus initiates DRX detection and paging detection. If the first wake-up signal or the second wake-up signal is received, it indicates that DRX detection and paging detection are initiated; if the first wake-up signal and the second wake-up signal are not received, it indicates that DRX detection and paging detection are not initiated.

[0271] In a possible design of this embodiment, the first wake-up signal carries first wake-up indication information, and the second wake-up signal carries second wake-up indication information. The first wake-up indication information and the second wake-up indication information are used to indicate whether the wake-up signal detection device starts DRX detection and paging detection and the start time.

[0272] In a possible design of this embodiment, the first wake-up signal is a signal having a first waveform, and the second wake-up signal is a signal having a second waveform;

[0273] The first waveform is obtained based on a single-carrier modulation scheme, and the second waveform is obtained based on a multi-carrier modulation scheme. Both the first and second waveforms are simple waveforms, and the modulation schemes used include amplitude modulation, frequency modulation, and phase modulation. Single-carrier modulation refers to a modulation technique that uses only one carrier within a fixed frequency band, while multi-carrier modulation refers to a modulation technique that uses multiple carriers within a fixed frequency band.

[0274] Figure 5 shows a schematic diagram of amplitude modulation provided by an exemplary embodiment of the present application. Exemplarily, the signal sequence corresponding to the first wake-up signal is 101010, and after modulating the unmodulated carrier based on this signal sequence, the waveform of the modulated carrier is obtained as shown in Figure 5.

[0275] In a possible design of this embodiment, the first waveform includes at least one of an OOK waveform, a binary phase shift keying (BSK) waveform, an ASK waveform, and a frequency shift keying (FSK) waveform; the second waveform includes an orthogonal frequency division multiplexing (OFDM) waveform.

[0276] In the related art, by using a second wake-up signal, the activation time (Active Time) of the DRX mechanism is entered when the second wake-up signal is received, thereby saving power. The second wake-up signal has a PDCCH waveform and can be called a normal wake-up signal. Its detection energy consumption is relatively high, which will lead to an increase in the working energy consumption of the detection device of the wake-up signal. In the embodiment of the present application, by using a first wake-up signal with lower detection energy consumption, further power saving can be achieved. By using the second wake-up signal, a larger communication area can be covered. By detecting at least one of the two wake-up signals in combination with specific scenarios, it is possible to adapt to different channel environments and save energy flexibly.

[0277] Figure 6 shows a schematic diagram of generating a first wake-up signal provided by an exemplary embodiment of the present application. In a possible design of this embodiment, the first wake-up indication information is information carried by the first wake-up signal, and the first wake-up indication information is converted into a signal sequence of length K, where K is a positive integer greater than 1. The conversion method includes at least one of upsampling, spread spectrum, and sequence mapping. Optionally, in the method of converting the first wake-up indication information in a sequence mapping manner, the sequence includes at least one of a constant envelope zero autocorrelation (CAZAC) sequence, a pseudo-noise (PN) sequence, a Gold sequence, an M sequence, and a Hadamard sequence.

[0278] The converted signal sequence is subjected to a discrete Fourier transform (DFT) to form multiple subcarrier signals. For example, the converted signal sequence y(n) is subjected to a DFT to obtain x(1), x(2) and so on to x(n). The multiple subcarrier signals generate a first wake-up signal through an inverse fast Fourier transform (IFFT). The waveform of the first wake-up signal in the time domain is expressed as a first waveform 610. Optionally, the multiple subcarrier signals can also be multiplexed with other NR signals before performing IFFT. Optionally, instead of performing DFT and IFFT on the converted signal sequence, single-carrier amplitude modulation is directly performed to obtain the first wake-up signal.

[0279] Optionally, the first wake-up signal is obtained by OOK modulation. OOK modulation is a process of modulating a digital sequence into a wireless signal with an MC-OOK waveform.

[0280] In one possible design of this embodiment, the first wake-up signal carries the ID information of the target wake-up signal detection device. In the case where the first wake-up signal carries the ID information of the target wake-up signal detection device, the target wake-up signal detection device receives the first wake-up signal.

[0281] In one possible design of this embodiment, the first wake-up signal carries the group ID information of the target wake-up signal detection device group. When the first wake-up signal carries the group ID information of the target wake-up signal detection device group, the first wake-up signal is received by all or some of the wake-up signal detection devices in the target wake-up signal detection device group.

[0282] In a possible design of this embodiment, the awakening of the awakening signal detection device is indicated by ID information or group ID information, or the awakening of the awakening signal detection device is indicated by mapping different ID information or group ID information into a bitmap.

[0292] In a possible design of this embodiment, the receiving module 1120 is configured to receive a measurement result of a measurement signal, where the measurement result of the measurement signal is a signal quality obtained by a detection device for a wake-up signal measuring the measurement signal.

[0294] In one possible design of this embodiment, the measurement result includes signal quality, and the signal quality is determined by the signal-to-noise ratio (SINR) or signal strength. SINR refers to the ratio of signal to noise, typically expressed in decibels (dB).
