If no WUS signal is received, or the WUS indicates not to wake up, the terminal device can keep the main radio in a sleep state. Therefore, the WUS signal plays an important role in waking up the main radio.

[0050] FIG1 is a schematic diagram of a communication system according to an exemplary embodiment. As shown in FIG1 , the communication system may include a terminal device 11 and a network device 12. The communication system may be used to support 4G network access technology, such as Long Term Evolution (LTE) access technology, or 5G network access technology, such as New Radio Access Technology (New RAT), or other future wireless communication technologies. It should be noted that in the communication system, the number of network devices 12 and terminal devices 11 may be one or more. The number of network devices 12 and terminal devices 11 in the communication system shown in FIG1 is only an adaptive example, and the present disclosure does not limit this.

[0051] The network device 12 in Figure 1 can be used to support access of the terminal device 11. For example, the network device 12 can be an evolutionary Node B (eNB or eNodeB) in LTE; the network device 12 can also be the next generation Node B (gNB or gNodeB) in a 5G network; the network device 12 can also be a radio access network (NG Radio Access Network, NG-RAN) device in a 5G network; the network device 12 can also be a base station, broadband network service gateway (Broadband Network Gateway, BNG), aggregation switch or non-3GPP (3rd Generation Partnership Project) access device in a future evolved public land mobile network (Public Land Mobile Network, PLMN), etc.

[0052] Optionally, the network device 12 in the embodiment of the present disclosure may include various forms of base stations, such as: macro base stations, micro base stations (also known as small stations), relay stations, access points, 5G base stations or future base stations, satellites, transmission points (Transmitting and Receiving Point, TRP), transmission points (Transmitting Point, TP), mobile switching centers, and devices to devices (Device-to-Device, D2D), machines to machines (Machine-to-Machine, M2M), Internet of Things (Internet of Things, IoT), vehicle-to-everything (V2X) or other devices that perform base station functions in communications, etc., and the embodiment of the present disclosure does not specifically limit this. For the convenience of description, in all embodiments of the present disclosure, the devices that provide wireless communication functions for the terminal device 11 are collectively referred to as network devices 12 or base stations.

[0053] The terminal device 11 in FIG. 1 may be an electronic device that provides voice or data connectivity. For example, the terminal device 11 may also be referred to as a user equipment (UE), a subscriber unit (SU), a mobile station (MS), a station (ST), a terminal, etc. For example, the terminal device 11 may include a smartphone, a smart wearable device, a smart speaker, a smart tablet, a wireless modem, a wireless local loop (WLL) station, a PDA (Personal Digital Assistant), a CPE (Customer Premise Equipment), etc. With the development of wireless communication technology, any device that can access a communication system, communicate with network devices of a communication system, communicate with other objects through a communication system, or any device that allows direct communication between two or more devices may be the terminal device 11 in the embodiments of the present disclosure; for example, terminals and cars in smart transportation, household appliances in smart homes, power meter reading instruments, voltage monitoring instruments, environmental monitoring instruments in smart grids, video monitoring instruments in smart security networks, cash registers, etc. In the embodiment of the present disclosure, the terminal device 11 can communicate with the network device 12. Multiple terminal devices 11 can also communicate with each other. The terminal device 11 can be static or mobile, which is not limited in the present disclosure.

[0054] In one embodiment, the terminal device 11 in FIG1 may be a terminal device supporting a power saving function. The terminal device may include a low power (LP) wake-up receiver (WUR) and a main radio (MR). The wake-up receiver may be referred to as an LP-WUR. For example, when the terminal device 11 is not transmitting or receiving data, the main radio may be in a sleep state to varying degrees.

[0055] In one implementation, the sleep state of the terminal device 11 may include one or more of ultra-deep sleep, deep sleep, light sleep, and micro sleep. The time required for the main radio of the terminal device 11 to wake up from different sleep states varies. Furthermore, due to differences in the hardware or software capabilities of the terminal devices 11, the time required for different terminal devices 11 to wake up from the same sleep state may also vary.

[0056] It should be noted that the terminal device 11 may be in an awake state after being awakened. The awake state of the terminal device 11 may be considered as a different state relative to the sleep state, or may be considered as a special form of the sleep state, and this disclosure does not limit this.

[0057] It should also be noted that the above-mentioned main radio may include a main transceiver and / or a main receiver. The main transceiver may be one or more, and the main receiver may also be one or more.

[0058] The terminal device 11 in FIG1 can support receiving low-power WUS signals.

[0059] In one embodiment, the terminal device may receive the WUS signal using a primary radio (primary transceiver and / or primary receiver).

[0060] In another embodiment, the terminal device may use a separate receiver to receive the WUS signal, and use a main transceiver to receive downlink signals and send uplink signals, or use a main receiver to receive downlink signals, and the main receiver and / or main transceiver may be referred to as the main radio of the terminal device. If the terminal device receives a WUS signal indicating that the terminal device is awake, the terminal device will turn on the main transceiver for transmitting, receiving and processing downlink / uplink information, or turn on the main receiver for receiving and processing downlink information; if the WUS signal is not received, or the WUS signal indicates not to wake up, the terminal device will maintain the sleep state of the main transceiver and / or main receiver, wherein the WUS signal can be applied to any state of the terminal device, such as RRC (Radio Resource Control) connected state, RRC idle state or RRC deactivated state.

[0061] In some embodiments, there are multiple ways to configure resources for low-power wake-up signals. When the signal quality is poor, more PRB resources (Physical Resource Block) are configured for low-power wake-up signals to improve transmission reliability; when the signal quality is poor, fewer PRB resources are configured for low-power wake-up signals to save more frequency domain resources.

[0062] Low-power wake-up signals are typically generated using a sequence. Due to modulation constraints, the sequence is related to the actual PRB resources used for transmission. Given a fixed PRB resource, the more energy the sequence accumulates in the time domain, the more beneficial the signal transmission. Furthermore, the terminal device must ensure that the sequence used to generate the low-power wake-up signal is effective for determining the energy threshold, providing a reference for determining the energy threshold. Therefore, the sequence used to generate the low-power wake-up signal requires further clarification.

[0063] Figure 2 is a flow chart of a method for determining a signal sequence according to some embodiments. As shown in Figure 2 , the method for determining a signal sequence may be used in a terminal device and includes the following steps.

[0064] In step S110 , a low-power wake-up signal sent by a network device is received.

[0065] In some embodiments, a terminal device can receive at least one low-power wake-up signal sent by a network device. As described above, the terminal device can use a primary radio to receive at least one low-power wake-up signal sent by a network device. The low-power wake-up signal can be used to change the sleep state of the primary radio in the terminal device.

[0066] In step S120 , a generation sequence of a low power consumption wake-up signal is determined.

[0067] In some embodiments, the low-power wake-up signal is obtained by the network device based on a generation sequence. For example, the terminal device may determine the generation sequence based on the low-power wake-up signal, the low-power synchronization signal, or sequence indication information sent by the network device. The specific method for determining the generation sequence of the low-power wake-up signal is not specifically limited here and may be selected based on actual circumstances.

[0068] As an example, the low-power wake-up signal generation sequence may be:

[0069] It is understandable that the determined low-power wake-up signal generation sequence can generate a low-power wake-up signal on a single channel, or can generate multiple low-power wake-up signals on multiple channels. In addition, the determined low-power wake-up signal generation sequence can be a set of sampling points corresponding to Fourier transform / inverse transform, a set of subcarrier coefficients, or information carrying the amount of information carried per unit time length of the low-power wake-up signal.

[0070] By determining the generation sequence of the low-power wake-up signal, the cumulative energy of the sequence can be obtained. Based on the cumulative energy, the energy threshold of the reference signal can be dynamically adjusted, thereby improving the accuracy of information determination.

[0071] The embodiments of the present disclosure provide that a terminal device can receive a low-power wake-up signal sent by a network device and can determine a generation sequence of the low-power wake-up signal. By determining the generation sequence corresponding to the low-power wake-up signal, the energy threshold can be flexibly adjusted.

[0072] Fig. 3 is a flow chart of a method for determining a signal sequence according to some other embodiments. As shown in Fig. 3 , the method for determining a signal sequence can be used in a terminal device and includes the following steps.

[0073] In step S210, the configuration resource of the low-power wake-up signal sent by the network device is obtained.

[0074] In the embodiment of the present disclosure, after receiving each low-power wake-up signal, the terminal device can obtain the configuration resource of each low-power wake-up signal and determine the generation sequence of the low-power wake-up signal based on the configuration resource of the low-power wake-up signal.

[0075] Here, the configuration resources of the low-power wake-up signal can be time domain resources, frequency domain resources, or time-frequency resources. Among them, time domain resources may include time domain symbols, time slots, radio frames, radio subframes, mini time slots (micro time slots), etc.; frequency domain resources may include RB (Resource Block), RE (Resource Element), RBG (Resource Block Group), and BWP (Bandwidth Part), etc.; time-frequency resources can be time domain resources of any unit and frequency domain resources of any unit. For example, time-frequency resources can be the previous time domain symbol of the time domain resource and the previous RB of the frequency domain resource.

[0076] In step S220 , a generation sequence of the low power wake-up signal is determined according to the configuration resources of the low power wake-up signal.

[0077] In some implementations, the terminal device may determine a low-power wake-up signal generation sequence based on a configuration resource for the low-power wake-up signal. The configuration resource for the low-power wake-up signal and the generation sequence for the low-power wake-up signal may have a certain correspondence. After obtaining the configuration resource for the low-power wake-up signal, the terminal device may determine the corresponding generation sequence for the low-power wake-up signal.

[0078] In a specific embodiment, the terminal device can obtain the time domain resources of the low-power wake-up signal sent by the network device, and on this basis, obtain the generation sequence of the low-power wake-up signal corresponding to the time domain resources. Here, the time domain resources of at least one low-power wake-up signal can correspond to one or a generation sequence. For example, when the time domain resources of the low-power wake-up signal are 2 symbols, the corresponding generation sequence of the low-power wake-up signal is the first generation sequence. For another example, when the time domain resources of the low-power wake-up signal are 5 symbols, the corresponding generation sequence of the low-power wake-up signal is the second generation sequence.

[0079] In another specific embodiment, the terminal device can obtain the frequency domain resources of the low-power wake-up signal sent by the terminal device, and on this basis, obtain the generation sequence of the low-power wake-up signal corresponding to the frequency domain resources. Here, the frequency domain resources of at least one low-power wake-up signal can correspond to one or a generation sequence. For example, when the frequency domain resources of the low-power wake-up signal are 2 PRBs, the corresponding generation sequence of the low-power wake-up signal is the first generation sequence. For another example, when the frequency domain resources of the low-power wake-up signal are 4 PRBs, the corresponding generation sequence of the low-power wake-up signal is the second generation sequence.

[0080] In another specific embodiment, the terminal device may obtain the time domain resources and frequency domain resources of the low-power wake-up signal sent by the terminal device, and on this basis, combine the time domain resources and frequency domain resources to obtain the corresponding low-power wake-up signal generation sequence. Here, the time domain resources and frequency domain resources of at least one low-power wake-up signal may correspond to one or a generation sequence. For example, when the time domain resources of the low-power wake-up signal are 2 symbols and the frequency domain resources are 2 PRBs, the corresponding low-power wake-up signal generation sequence is the first generation sequence.

[0081] It should be noted that when combining the time domain resources and frequency domain resources of the low-power wake-up signal to obtain the generation sequence corresponding to the low-power wake-up signal, the terminal device can first calculate the product of the time domain resources and the frequency domain resources of the low-power wake-up signal. On this basis, the corresponding generation sequence is obtained based on the calculation result. For example, when the number of symbols of the time domain resources of the low-power wake-up signal * the number of PRBs of the frequency domain resources is greater than the first value, the generation sequence of the low-power wake-up signal is determined to be the first generation sequence. For another example, when the number of symbols of the time domain resources of the low-power wake-up signal * the number of PRBs of the frequency domain resources is greater than the second value, the generation sequence of the low-power wake-up signal is determined to be the second generation sequence.

[0082] In the disclosed embodiments, the configuration resource of the low-power wake-up signal may be indicated by higher-layer signaling or dynamic signaling. For example, the configuration resource of the low-power wake-up signal may be carried in signaling such as higher-layer signaling RRC, dynamic signaling DCI (Downlink Control Information), and MAC CE (MAC Control Element).

[0083] In summary, the embodiments of the present disclosure can pre-define N generation sequences, and the time domain resources / frequency domain resources / time-frequency resources of different low-power wake-up signals can correspond to different generation sequences, that is, at least one time domain resource / frequency domain resource / time-frequency resource of a low-power wake-up signal can correspond to one generation sequence. For example, two generation sequences are pre-defined, the first resource and the second resource of the low-power wake-up signal correspond to the first generation sequence, and the third resource of the low-power wake-up signal corresponds to the second generation sequence. Among them, the first resource, the second resource and the third resource of the low-power wake-up signal can be time domain resources, frequency domain resources or time-frequency resources.

[0084] It should be noted that, for multiple embodiments or features separated by "or", even if some of the features are not achievable, it will not affect other solutions. In addition, the embodiments of the present disclosure can be combined with other embodiments or implementations of the signal sequence determination method for terminal devices and their various optional solutions, unless there is any contradiction, which will not be repeated here.

[0085] The embodiments of the present disclosure stipulate that the terminal device can receive a low-power wake-up signal sent by a network device and can obtain the configuration resources of the low-power wake-up signal. On this basis, the configuration resources of the low-power wake-up signal are used to determine the generation sequence of the low-power wake-up signal, so that the generation sequence can be obtained accurately and effectively.

[0086] Fig. 4 is a flow chart of a method for determining a signal sequence according to some further embodiments. As shown in Fig. 4 , the method for determining a signal sequence can be used in a terminal device and includes the following steps.

[0087] In step S310, the configuration resource of the low power consumption reference signal sent by the network device is obtained.

[0088] In the disclosed embodiments, before receiving at least one low-power wake-up signal, the terminal device may receive at least one low-power reference signal, and then obtain the configuration resources for each low-power reference signal. Based on this, the terminal device determines a sequence for generating the low-power wake-up signal based on the configuration resources for the low-power reference signal.

[0089] Here, the configuration resources of the low-power reference signal can be time domain resources, frequency domain resources, or both time domain resources and frequency domain resources. Among them, time domain resources can include time domain symbols, time slots, radio frames, radio subframes, mini time slots, etc.; frequency domain resources can include RBs, REs, RBGs, etc.; time-frequency resources can be time domain resources of any unit and frequency domain resources of any unit. For example, time-frequency resources can be the previous time domain symbol of the time domain resource and the previous RB of the frequency domain resource.

[0090] In step S320 , a generation sequence of a low-power wake-up signal is determined according to the configuration resources of the low-power reference signal.

[0091] In some implementations, the terminal device may determine a low-power wake-up signal generation sequence based on a configuration resource of a low-power reference signal. The configuration resource of the low-power reference signal and the generation sequence of the low-power wake-up signal may have a certain correspondence. After obtaining the configuration resource of the low-power reference signal, the terminal device may determine the corresponding generation sequence of the low-power wake-up signal.

[0092] In a specific embodiment, the terminal device can obtain the time domain resources of the low-power reference signal sent by the network device, and on this basis, obtain the generation sequence of the low-power wake-up signal corresponding to the time domain resources. Here, the time domain resources of at least one low-power reference signal can correspond to one or a generation sequence. For example, when the time domain resources of the low-power reference signal are 2 symbols, the corresponding generation sequence of the low-power wake-up signal is the first generation sequence. For another example, when the time domain resources of the low-power reference signal are 5 symbols, the corresponding generation sequence of the low-power wake-up signal is the second generation sequence.

[0093] In another specific embodiment, the terminal device can obtain the frequency domain resources of the low-power reference signal sent by the terminal device, and on this basis, obtain the generation sequence of the low-power wake-up signal corresponding to the frequency domain resources. Here, the frequency domain resources of at least one low-power reference signal can correspond to one or a generation sequence. For example, when the frequency domain resources of the low-power reference signal are 2 PRBs, the corresponding generation sequence of the low-power wake-up signal is the first generation sequence. For another example, when the frequency domain resources of the low-power reference signal are 4 PRBs, the corresponding generation sequence of the low-power wake-up signal is the second generation sequence.

[0094] In another specific embodiment, the terminal device may obtain the time domain resources and frequency domain resources of the low-power reference signal sent by the terminal device, and on this basis, combine the time domain resources and frequency domain resources to obtain the corresponding low-power wake-up signal generation sequence. Here, the time domain resources and frequency domain resources of at least one low-power reference signal may correspond to one or a generation sequence. For example, when the time domain resources of the low-power reference signal are 2 symbols and the frequency domain resources are 2 PRBs, the corresponding low-power wake-up signal generation sequence is the first generation sequence.

[0095] It should be noted that when combining the time domain resources and frequency domain resources of the low-power reference signal to obtain the generation sequence corresponding to the low-power wake-up signal, the terminal device can first calculate the product of the time domain resources and the frequency domain resources of the low-power reference signal. On this basis, the corresponding generation sequence is obtained based on the calculation result. For example, when the number of symbols of the time domain resources of the low-power reference signal * the number of PRBs of the frequency domain resources is greater than the first value, the generation sequence of the low-power wake-up signal is determined to be the first generation sequence. For another example, when the number of symbols of the time domain resources of the low-power reference signal * the number of PRBs of the frequency domain resources is greater than the second value, the generation sequence of the low-power wake-up signal is determined to be the second generation sequence.

[0096] In the embodiment of the present disclosure, the configuration resources of the low power reference signal can be indicated by higher layer signaling or dynamic signaling. For example, the configuration resources of the low power reference signal can be carried in higher layer signaling RRC, dynamic signaling DCI, MAC CE and other signaling.

[0097] In summary, the embodiments of the present disclosure can pre-define N generation sequences, and different time domain resources / frequency domain resources / time-frequency resources of low-power reference signals can correspond to different generation sequences, that is, the time domain resources / frequency domain resources / time-frequency resources of at least one low-power reference signal can correspond to one generation sequence. For example, two generation sequences are pre-defined, the first resource and the second resource of the low-power reference signal correspond to the first generation sequence, and the third resource of the low-power reference signal corresponds to the second generation sequence, wherein the first resource, the second resource, and the third resource of the low-power reference signal can be time domain resources, frequency domain resources, or time-frequency resources.

[0098] The embodiments of the present disclosure stipulate that the terminal device can receive a low-power reference signal sent by a network device and can obtain the configuration resources of the low-power reference signal. On this basis, the configuration resources of the low-power reference signal are used to determine the generation sequence of the low-power wake-up signal, so that the generation sequence can be obtained quickly and effectively.

[0099] Fig. 5 is a flow chart of a method for determining a signal sequence according to some further embodiments. As shown in Fig. 5 , the method for determining a signal sequence can be used in a terminal device and includes the following steps.

[0100] In step S410, the configuration resource of the low-power synchronization signal sent by the network device is acquired.

[0101] In the disclosed embodiment, before receiving at least one low-power wake-up signal, the terminal device may receive at least one low-power synchronization signal, and then the terminal device may obtain the configuration resources of each low-power synchronization signal. Based on this, the terminal device determines the generation sequence of the low-power wake-up signal according to the configuration resources of the low-power synchronization signal.

[0102] Here, the configuration resources of the low-power synchronization signal can be time domain resources, frequency domain resources, or both time domain resources and frequency domain resources. Among them, time domain resources can include time domain symbols, time slots, radio frames, radio subframes, mini time slots, etc.; frequency domain resources can include RBs, REs, RBGs, etc.; time-frequency resources can be time domain resources of any unit and frequency domain resources of any unit. For example, time-frequency resources can be the previous time domain symbol of the time domain resource and the previous RB of the frequency domain resource.

[0103] In step S420 , a generation sequence of a low-power wake-up signal is determined according to the configuration resources of the low-power synchronization signal.

[0104] In some implementations, the terminal device may determine a low-power wake-up signal generation sequence based on a configuration resource for the low-power synchronization signal. The configuration resource for the low-power synchronization signal and the generation sequence for the low-power wake-up signal may have a certain correspondence. After obtaining the configuration resource for the low-power synchronization signal, the terminal device may determine the corresponding low-power wake-up signal generation sequence.

[0105] In a specific embodiment, the terminal device can obtain the time domain resources of the low-power synchronization signal sent by the network device, and on this basis, obtain the generation sequence of the low-power wake-up signal corresponding to the time domain resources. Here, the time domain resources of at least one low-power synchronization signal can correspond to one or a generation sequence. For example, when the time domain resources of the low-power synchronization signal are 2 symbols, the corresponding generation sequence of the low-power wake-up signal is the first generation sequence. For another example, when the time domain resources of the low-power synchronization signal are 5 symbols, the corresponding generation sequence of the low-power wake-up signal is the second generation sequence.

[0106] In another specific embodiment, the terminal device can obtain the frequency domain resources of the low-power synchronization signal sent by the terminal device, and on this basis, obtain the generation sequence of the low-power wake-up signal corresponding to the frequency domain resources. Here, the frequency domain resources of at least one low-power synchronization signal can correspond to one or a generation sequence. For example, when the frequency domain resources of the low-power synchronization signal are 2 PRBs, the corresponding generation sequence of the low-power wake-up signal is the first generation sequence. For another example, when the frequency domain resources of the low-power synchronization signal are 4 PRBs, the corresponding generation sequence of the low-power wake-up signal is the second generation sequence.

[0107] In another specific embodiment, the terminal device may obtain the time domain resources and frequency domain resources of the low-power synchronization signal sent by the terminal device, and on this basis, combine the time domain resources and frequency domain resources to obtain the corresponding low-power wake-up signal generation sequence. Here, the time domain resources and frequency domain resources of at least one low-power synchronization signal may correspond to one or a generation sequence. For example, when the time domain resources of the low-power synchronization signal are 2 symbols and the frequency domain resources are 2 PRBs, the corresponding low-power wake-up signal generation sequence is the first generation sequence.

[0108] It should be noted that when combining the time domain resources and frequency domain resources of the low-power synchronization signal to obtain the generation sequence corresponding to the low-power wake-up signal, the terminal device can first calculate the product of the time domain resources and the frequency domain resources of the low-power synchronization signal. On this basis, the corresponding generation sequence is obtained based on the calculation result. For example, when the number of symbols in the time domain resources of the low-power synchronization signal * the number of PRBs in the frequency domain resources is greater than the first value, the generation sequence of the low-power wake-up signal is determined to be the first generation sequence. For another example, when the number of symbols in the time domain resources of the low-power synchronization signal * the number of PRBs in the frequency domain resources is greater than the second value, the generation sequence of the low-power wake-up signal is determined to be the second generation sequence.

[0109] In the embodiment of the present disclosure, the configuration resource of the low power synchronization signal can be indicated by high-layer signaling or dynamic signaling. For example, the configuration resource of the low power synchronization signal can be carried in high-layer signaling RRC, dynamic signaling DCI, MAC CE and other signaling.

[0110] In summary, the embodiments of the present disclosure can pre-define N generation sequences, and the time domain resources / frequency domain resources / time-frequency resources of different low-power synchronization signals can correspond to different generation sequences, that is, the time domain resources / frequency domain resources / time-frequency resources of at least one low-power synchronization signal can correspond to one generation sequence. For example, two generation sequences are pre-defined, the first resource and the second resource of the low-power synchronization signal correspond to the first generation sequence, and the third resource of the low-power synchronization signal corresponds to the second generation sequence, wherein the first resource, the second resource, and the third resource of the low-power synchronization signal can be time domain resources, frequency domain resources, or time-frequency resources.

[0111] It should be noted that, for multiple embodiments or features separated by "or", even if some of the features are not achievable, it will not affect other solutions. In addition, the embodiments of the present disclosure can be combined with other embodiments or implementations of the signal sequence determination method for terminal devices and their various optional solutions, unless there is any contradiction, which will not be repeated here.

[0112] The embodiments of the present disclosure stipulate that the terminal device can receive the low-power synchronization signal sent by the network device and can obtain the configuration resources of the low-power synchronization signal. On this basis, the configuration resources of the low-power communication signal are used to determine the generation sequence of the low-power wake-up signal, so that the generation sequence can be obtained quickly and effectively.

[0114] In step S510, a first signaling sent by a network device is received.

[0115] In some implementations, the terminal device may receive a first signaling sent by the network device, wherein the first signaling may be used to carry the sequence index information. In addition, the first signaling may be carried by a high-layer signaling RRC, a dynamic signaling DCI, a MAC CE, or other signaling.

[0116] In the disclosed embodiment, the first signaling may be sent to the terminal device together with the low-power wake-up signal, may be sent to the terminal device before the low-power wake-up signal, or may be sent after the low-power wake-up signal is sent. The order of sending the first signaling and the low-power wake-up signal is not explicitly limited and can be selected based on actual circumstances.

[0117] In step S520 , a generation sequence of the low power consumption wake-up signal is determined according to the sequence index information.

[0118] As an optional manner, the terminal device may predefine N generation sequences. After receiving the first signaling sent by the network device, the terminal device may determine the generation sequence of the low-power wake-up signal based on the sequence index information carried by the first signaling. Here, the sequence index indicated by the sequence index information may uniquely correspond to one generation sequence, that is, one sequence index may correspond to one generation sequence.

[0119] As an example, the sequence index information is 2 bits, 00 represents index 0; 01 represents index 1; 10 represents index 1; and 11 represents index 2. Different indices have different corresponding low-power wake-up signal generation sequences. For example, when the sequence index information is 01, the corresponding low-power refresh signal generation sequence is the first generation sequence. For another example, when the sequence index information is 10, the corresponding low-power refresh signal generation sequence is the second generation sequence.

[0120] It should be noted that, for multiple embodiments or features separated by "or", even if some of the features are not achievable, it will not affect other solutions.

In addition, the second signaling may be carried by a high-layer signaling RRC, a dynamic signaling DCI, a MAC CE, or other signaling.

[0125] In the disclosed embodiments, the second signaling may be sent to the terminal device together with the low-power wake-up signal, may be sent to the terminal device before the low-power wake-up signal, or may be sent after the low-power wake-up signal is sent. The order of sending the second signaling and the low-power wake-up signal is not explicitly limited and can be selected based on actual circumstances.

[0126] In step S620 , a generation sequence of the low power consumption wake-up signal is determined according to the sequence indication information.

[0127] As an optional manner, the terminal device may predefine N generation sequences. After receiving the second signaling sent by the network device, the terminal device may determine the generation sequence of the low-power wake-up signal based on the sequence indication information carried by the second signaling, that is, the generation sequence of the corresponding low-power wake-up signal is indicated by the sequence indication information. Specifically, the sequence indication information may be n bits, and each bit from high to low may correspond to a different generation sequence.

[0128] As an example, the sequence indication information is 4 bits, and the 1st, 2nd, 3rd, and 4th bits from high to low can correspond to different generation sequences. For example, when the sequence indication information is 1000, the generation sequence of the low-power wake-up signal is the first generation sequence. For another example, when the sequence indication information is 0100, the generation sequence of the low-power wake-up signal is the second generation sequence.

[0152] Figure 11 is a flow chart of a signal sequence determination method according to some further embodiments. As shown in Figure 11 , the signal sequence determination method can be used in a terminal device and includes the following steps.

[0153] In step 1010 , a reference sequence corresponding to a reference domain of a low-power wake-up signal is determined.

[0154] In the disclosed embodiment, the low-power wake-up signal may include a reference domain and a data domain, so the terminal device may determine the generation sequence of the low-power wake-up signal through the reference domain within the low-power wake-up signal. Specifically, the terminal device may first determine the reference sequence corresponding to the reference domain within the low-power wake-up signal.

[0163] In step S1130 , the energy threshold of the reference signal is adjusted according to the generation sequence of the low power consumption wake-up signal.

[0164] In some embodiments, after determining the low-power wake-up signal generation sequence, the terminal device can adjust the reference signal threshold based on the low-power wake-up signal generation sequence. In other words, the terminal device can adjust the reference signal determination threshold based on the low-power wake-up signal generation sequence. Based on this, the adjusted energy threshold is used to determine the information to be sent.

Therefore, the maximum energy accumulated on the time domain symbol can be 16, that is, the energy threshold is adjusted to 16. On this basis, the terminal device can determine the symbol to be sent according to the adjusted energy threshold 16. If the energy of the symbol to be sent is greater than the adjusted energy threshold 16, the symbol to be sent is determined to be an on symbol, which represents information A; otherwise, the symbol to be sent is determined to be an off symbol, which represents information B.
