[0057] To facilitate understanding of the technical solutions of the embodiments of the present application, the relevant technologies of the present application are explained.

[0058] 1. Zero-power communication

[0059] The key technologies of zero-power communication include energy harvesting, backscatter communication and low-power technology.

[0060] As shown in Figure 2, a typical zero-power communication system (such as an RFID system) includes a network device (such as an RFID system reader) and a zero-power device (such as an electronic tag). The network device is used to send wireless power supply signals and downlink communication signals to the zero-power device and receive backscattered signals from the zero-power device. A basic zero-power device includes an energy harvesting module, a backscatter communication module, and a low-power computing module. In addition, the zero-power device may also have a memory or sensor for storing some basic information (such as item identification, etc.) or sensor data such as ambient temperature and ambient humidity.

[0061] For example, the energy harvesting module can collect energy carried by radio waves in space (Figure 2 shows radio waves emitted by network devices) to drive the low-power computing module of the zero-power device and implement backscatter communication. After obtaining energy, the zero-power device can receive control commands from the network device and send data to the network device based on control signaling using backscattering. The data sent can be data stored in the zero-power device itself (such as an identity identifier or pre-written information, such as the product's production date, brand, manufacturer, etc.). The zero-power device can also be loaded with various sensors, so that the data collected by various sensors can be reported based on the zero-power mechanism.

[0062] The following describes the key technologies in zero-power communication.

[0063] 1. RF Power Harvesting

[0064] As shown in Figure 3, the RF energy harvesting module uses the principle of electromagnetic induction to harvest electromagnetic wave energy from space, thereby obtaining the energy needed to operate zero-power devices. This energy is used to drive low-power demodulation and modulation modules, sensors, and memory readout. Therefore, zero-power devices do not require traditional batteries.

[0065] 2. Back Scattering

[0066] As shown in Figure 4, a zero-power device receives a carrier signal sent by a network device, modulates it, loads the information to be transmitted, and radiates the modulated signal from the antenna. This information transmission process is called backscatter communication. Backscatter and load modulation are closely related. Load modulation achieves this by adjusting and controlling the circuit parameters of the zero-power device's oscillator circuit according to the data stream's rhythm, causing parameters such as the zero-power device's impedance to change accordingly. Load modulation techniques primarily include resistive load modulation and capacitive load modulation. In resistive load modulation, a resistor is connected in parallel with the load, which is turned on or off based on the binary data stream, as shown in Figure 5. The switching of the resistor causes a change in the circuit voltage, thus implementing amplitude-shifted keying (ASK) modulation. This modulation and transmission is achieved by adjusting the amplitude of the zero-power device's backscattered signal. Similarly, in capacitive load modulation, the switching of the capacitor changes the circuit's resonant frequency, enabling frequency-shifted keying (FSK) modulation. This modulation and transmission is achieved by adjusting the operating frequency of the zero-power device's backscattered signal.

[0067] It can be seen that the zero-power device uses load modulation to modulate the incoming signal, thereby realizing the backscatter communication process. Therefore, the zero-power device has significant advantages:

[0068] (1) It does not actively transmit signals, so it does not require complex RF links, such as PA, RF filters, etc.

[0069] (2) There is no need to actively generate high-frequency signals, so no high-frequency crystal oscillator is required;

[0070] (3) With the help of backscatter communication, terminal signal transmission does not need to consume the terminal's own energy.

[0071] 3. Coding technology

[0072] Data transmitted by zero-power devices can use various codes to represent binary "1s" and "0s." RFID systems typically use one of the following encoding methods: non-return-to-zero (NRZ), Manchester, unipolar return-to-zero, differential bi-phase (DBP), differential, pulse interval encoding (PIE), bidirectional space encoding (FMO), Miller, and differential encoding. In simple terms, different encoding techniques use different pulse signals to represent 0s and 1s.

[0073] In some scenarios, based on the energy source and usage of zero-power devices, zero-power devices can be divided into the following types:

[0074] 1. Passive zero-power devices

[0075] Zero-power devices (such as electronic tags in RFID systems) do not require internal batteries. When a zero-power device is close to a network device (such as an RFID reader), it is within the near-field radiation generated by the network device's antenna. Consequently, the zero-power device's antenna generates an induced current through electromagnetic induction, which drives the device's low-power chip circuitry. This enables forward link signal demodulation and reverse link (or reflection link) signal modulation. For backscatter links, the zero-power device uses backscattering to transmit signals.

[0076] It can be seen that the passive zero-power device does not require a built-in battery to drive either the forward link or the reverse link, and is a truly zero-power device.

[0077] Passive zero-power devices do not require batteries, and the RF circuit and baseband circuit are very simple. For example, they do not require low-noise amplifiers (LNAs), power amplifiers (PAs), crystal oscillators, analog-to-digital converters (ADCs), and other devices. Therefore, they have many advantages such as small size, light weight, very low price, and long service life.

[0078] Passive zero-power terminals can also support other energy collection methods. By collecting energy from the environment (such as light energy, thermal energy, kinetic energy, mechanical energy, etc.), they can obtain energy for driving circuits and support terminal devices to communicate.

[0079] 2. Semi-passive zero-power devices

[0080] Semi-passive zero-power devices do not have conventional batteries installed themselves, but can use RF energy harvesting modules to harvest radio wave energy or use energy harvesting modules to harvest energy from the environment (such as solar energy, thermal energy, mechanical vibration energy, etc.), and store the harvested energy in an energy storage unit (such as a capacitor). After the energy storage unit obtains energy, it can drive the low-power chip circuit of the zero-power device. It can realize tasks such as demodulation of forward link signals and modulation of reverse link signals. For backscatter links, zero-power devices use backscatter implementation to transmit signals. Alternatively, based on the harvested energy, zero-power devices can use low-power transmitters for active transmission communication.

[0081] It can be seen that the semi-passive zero-power device does not require a built-in battery to drive either the forward link or the reverse link. Although it uses energy stored in capacitors during operation, the energy comes from the radio energy collected by the energy harvesting module. Therefore, it is also a truly zero-power device.

[0082] Semi-passive zero-power devices inherit many advantages of passive zero-power devices, so they have many advantages such as small size, light weight, very low price, and long service life.

[0083] 3. Active zero-power devices

[0084] In some scenarios, zero-power devices can also be active zero-power devices, which can have built-in batteries. The batteries power the low-power chip circuitry in these devices, enabling forward link signal demodulation and reverse link signal modulation. However, for backscatter links, zero-power devices use backscattering to transmit signals. Therefore, the zero-power nature of these devices lies primarily in the fact that reverse link signal transmission does not require the terminal's own power, but rather utilizes backscattering.

[0085] Active zero-power terminals have built-in batteries that power the RFID chip, increasing their read and write distance and improving communication reliability. Therefore, they are suitable for scenarios with relatively high requirements for communication distance and read latency.

[0086] In some scenarios, zero-power devices can be categorized as follows based on transmitter type:

[0087] 1) Zero-power devices based on backscattering

[0088] These zero-power devices use the aforementioned backscattering method to transmit uplink data. These devices lack an active transmitter, only a backscattering transmitter. Therefore, when these zero-power devices transmit data, they require network equipment to provide a carrier, which they then use to perform backscattering to achieve data transmission.

[0089] 2) Zero-power devices based on active transmitters

[0090] This type of zero-power device uses an active transmitter with active transmission capabilities for uplink data transmission. Therefore, when sending data, this type of zero-power device can use its own active transmitter to send data without the need for network equipment to provide a carrier. Active transmitters suitable for zero-power devices can include ultra-low-power ASK and ultra-low-power FSK transmitters. When transmitting a 100uW signal, the overall power consumption can be reduced to 400-600uW.

[0091] 3) Zero-power devices with both backscatter transmitters and active transmitters

[0092] These zero-power devices can support both backscatter and active transmitters. They can determine which signal transmission method to use, namely, active or backscatter, based on different conditions (such as battery life and available ambient energy) or based on network device scheduling.

[0093] With the rapid development of the Internet of Things, existing IoT communication technologies can no longer meet the IoT communication needs in many scenarios, such as:

[0094] 1. Harsh communication environment

[0095] Certain IoT scenarios may face extreme environments such as high temperature, extremely low temperature, high humidity, high voltage, high radiation, or high-speed movement. Examples include ultra-high voltage substations, high-speed train track monitoring, environmental monitoring in high-altitude cold regions, and industrial production lines. In these scenarios, existing IoT terminals will not function due to the operating environment limitations of conventional power supplies. Furthermore, extreme operating environments are not conducive to IoT maintenance, such as battery replacement.

[0096] 2. Demand for extremely small terminal form factors

[0097] Certain IoT communication scenarios, such as food traceability, commodity distribution, and smart wearables, require terminals to be extremely small for ease of use. For example, IoT terminals used for commodity management in the distribution process often take the form of electronic tags, embedded in product packaging in a very compact form factor. Another example is lightweight wearable devices that can meet user needs while improving the user experience.

[0098] 3. Extremely low-cost IoT communication requirements

[0099] Many IoT communication scenarios require IoT terminals to be sufficiently affordable to enhance their competitiveness compared to alternative technologies. For example, in logistics or warehousing, to facilitate the management of large quantities of circulating items, IoT terminals can be attached to each item. Communication between the terminal and the logistics network enables precise management of the entire logistics process and lifecycle. These scenarios require IoT terminals to be competitively priced.

[0100] Therefore, in order to cover these unmet IoT communication needs, cellular networks also need to develop ultra-low-cost, extremely small-size, battery-free / maintenance-free IoT, and zero-power IoT can just meet this need.

[0101] The zero-power Internet of Things (IoT) can also be referred to as the ambient power enabled IoT (Ambient IoT or AMP IoT). Zero-power devices are also called Ambient IoT devices or AMP IoT devices. Ambient IoT devices can refer to IoT devices that use various ambient energies, such as radio frequency energy, light energy, solar energy, thermal energy, and mechanical energy. These devices can have no energy storage capacity or very limited energy storage capacity, such as using capacitors with a capacity of tens of microfarads.

[0102] Ambient IoT can be used in at least four scenarios:

[0103] 1. Object recognition, such as logistics, production line product management, and supply chain management;

[0104] 2. Environmental monitoring, such as temperature, humidity, and harmful gas monitoring of the working environment and natural environment;

[0105] 3. Positioning, such as indoor positioning, intelligent object search, production line item positioning, etc.

[0106] 4. Intelligent control, such as intelligent control of various electrical appliances in smart homes (turning on and off air conditioners, adjusting temperature), and intelligent control of various facilities in agricultural greenhouses (automatic irrigation and fertilization).

[0107] 2. Cellular Passive IoT

[0108] As 5G industry applications expand, the types of connected objects and application scenarios will increase, placing higher demands on the cost and power consumption of communication terminals. The application of battery-free, low-cost passive IoT devices has become a key technology for cellular IoT, expanding the types and number of terminals connected to 5G networks and truly realizing the interconnection of everything. Passive IoT devices can be based on zero-power communication technologies, such as RFID, and can be extended to suit cellular IoT.

[0109] To facilitate understanding of the embodiments of the present application, the power supply signal, scheduling signal and carrier signal related to zero-power communication are explained.

[0110] 1. Energy supply signal

[0111] The energy supply signal is the energy source for the zero-power device to harvest energy.

[0112] From the perspective of energy supply signal carriers, it can be base stations, smart phones, smart gateways, charging stations, micro base stations, etc.

[0113] In terms of frequency band, the frequency band of radio waves used for energy supply can be low frequency, medium frequency, high frequency, etc.

[0114] In terms of waveform, the radio waves used for power supply can be sine waves, square waves, triangle waves, pulses, rectangular waves, etc.

[0115] In addition, the power supply signal can be a continuous wave or a discontinuous wave (ie, a certain period of interruption is allowed).

[0116] Optionally, the energy supply signal can be an existing signal in the 3GPP standard, such as a sounding reference signal (SRS), a physical uplink shared channel (PUSCH), a physical random access channel (PRACH), a physical uplink control channel (PUCCH), a physical downlink control channel (PDCCH), a physical downlink shared channel (PDSCH), a physical broadcast channel (PBCH), etc., or it can be a WiFi signal or a Bluetooth signal.

[0117] Optionally, the energy supply signal may also be implemented by adding a new signal, for example, adding a signal dedicated to energy supply.

[0118] 2. Trigger signal or scheduling signal

[0119] The trigger signal is used to trigger or schedule the zero-power device to transmit data.

[0120] From the perspective of trigger signal carrier, it can be a base station, smart phone, smart gateway, etc.

[0121] In terms of frequency band, the radio waves used for triggering or scheduling can be low frequency, medium frequency, high frequency, etc.

[0122] In terms of waveform, the radio wave used for triggering or scheduling can be a sine wave, square wave, triangle wave, pulse, rectangular wave, etc.

[0123] In addition, the trigger signal can be a continuous wave or a discontinuous wave (ie, a certain period of interruption is allowed).

[0124] Optionally, the trigger signal may be an existing signal in the 3GPP standard, such as SRS, PUSCH, PRACH, PUCCH, PDCCH, PDSCH, PBCH, or a WIFI signal or a Bluetooth signal.

[0125] Optionally, the trigger signal may also be implemented by adding a new signal, for example, adding a signal dedicated to triggering or scheduling.

[0126] 3. Carrier signal

[0127] The carrier signal is used by the zero-power device to generate a backscatter signal. For example, the zero-power device may modulate the received carrier signal according to the information to be sent to form a backscatter signal.

[0128] From the perspective of carrier signal carrier, it can be a base station, smart phone, smart gateway, etc.

[0129] In terms of frequency band, the radio waves used as carrier signals can be low frequency, medium frequency, high frequency, etc.

[0130] In terms of waveform, the radio wave used as the carrier signal can be a sine wave, square wave, triangle wave, pulse, rectangular wave, etc.

[0131] In addition, the carrier signal can be a continuous wave or a discontinuous wave (ie, a certain period of interruption is allowed).

[0132] Optionally, the carrier signal may be an existing signal in the 3GPP standard, such as SRS, PUSCH, PRACH, PUCCH, PDCCH, PDSCH, PBCH, or a WIFI signal or a Bluetooth signal.

[0133] Optionally, the carrier signal may also be implemented by adding a new signal, for example, adding a carrier signal dedicated to generating a backscatter signal.

[0134] It should be noted that in the embodiment of the present application, the power supply signal, the scheduling signal and the carrier signal can be the same signal, or they can be different signals. For example, the power supply signal can be used as a carrier signal, and the scheduling signal can also be used as a carrier signal, etc.

[0135] In some scenarios, to reduce air interface signaling and quickly restore wireless connections and data services, a new Radio Resource Control (RRC) state, RRC_INACTIVE, is defined. This state is different from the RRC_IDLE and RRC_CONNECTED states.

[0136] In the RRC_IDLE state, mobility is based on cell selection and reselection by the terminal device, paging is initiated by the core network (CN), and the paging area is configured by the CN. There is no terminal device access stratum (AS) context on the base station side, and no RRC connection exists.

[0137] In the RRC_CONNECTED state, an RRC connection exists, and a device AS context exists between the base station and the terminal. The network knows the terminal's location at the cell level. Mobility is controlled by the network. Unicast data can be transmitted between the terminal and the base station.

[0138] RRC_INACTIVE: Mobility is based on cell selection and reselection of the terminal device. There is a connection between CN and NR. The AS context of the terminal device exists on a certain base station. Paging is triggered by the Radio Access Network (RAN). The RAN-based paging area is managed by the RAN. The network equipment knows the location of the terminal device based on the RAN paging area level.

[0139] In some scenarios, to save power for terminals, a discontinuous reception (DRX) mechanism is introduced. This allows the terminal to enter a discontinuous reception state when there is no data to receive, rather than having to keep the receiver on. Specifically, the network device can configure the terminal to wake up during the on duration and monitor the Physical Downlink Control Channel (PDCCH), and sleep at other times. That is, the terminal does not need to monitor the PDCCH.

[0140] The evolution of NR technology has placed higher demands on terminal power conservation. For example, with the existing DRX mechanism, during each on-duration, the UE needs to continuously monitor the PDCCH to determine whether the base station has scheduled data transmission for it. However, for most UEs, there may be long periods without the need to receive data, but they still need to wake up regularly to monitor possible downlink transmissions. For these UEs, there is room for further optimization of terminal power conservation.

[0141] In some scenarios, to further reduce the power consumption of terminals in the RRC_CONNECTED state, power saving signaling is introduced. This signaling is used in conjunction with the DRX mechanism, and the terminal receives an indication of the power saving signal before the on duration. When the terminal has data to transmit during the upcoming on duration, the network "wakes up" the terminal through the power saving signal so that it can monitor the PDCCH during the upcoming on duration. Otherwise, the network instructs the terminal to continue "sleeping" through the power saving signal, and the terminal does not need to monitor the PDCCH during the upcoming on duration. Compared to the existing DRX mechanism, when the terminal has no data to transmit, the terminal can omit monitoring the PDCCH during the on duration, thereby achieving energy saving for the terminal.

[0142] In some scenarios, the power consumption of terminals in RRC_IDLE and RRC_INACTIVE states mainly comes from periodic discontinuous reception of paging, which includes the power consumption of time-frequency synchronization recovery and automatic gain control (AGC) before the paging opportunity arrives, and the power consumption of detecting the paging PDCCH during the paging opportunity. To further save energy for terminals in RRC_INACTIVE and RRC_IDLE states, an energy-saving signal for paging reception, called Paging Early Indication (PEI), is introduced. It is used to indicate whether the terminal needs to receive paging on the paging opportunity before the terminal's paging opportunity arrives.

[0143] In some scenarios, in order to further save power on the terminal, it is considered to introduce a low power wake-up receiver (LP-WUR) to monitor the low power wake-up signaling (LP-WUS). When the LP-WUS is received from the network device, the LP-WUR wakes up the main radio (MR) of the terminal device.

[0144] Due to the simplicity of LP-WUR implementation, low device complexity, and low-power operation, the corresponding LP-WUS also uses simple coding and modulation methods. This can easily lead to a shorter coverage range for the LP-WUS signal, which is lower than the coverage performance of the PDCCH and Physical Uplink Shared Channel (PUSCH) in some scenarios.

[0145] Therefore, how to send LP-WUS to improve the coverage and transmission performance of LP-WUS is an urgent problem to be solved.

[0146] To facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific embodiments. The above related technologies can be combined arbitrarily with the technical solutions of the embodiments of the present application as optional solutions, and all of them fall within the scope of protection of the embodiments of the present application. The embodiments of the present application include at least part of the following contents.

[0147] FIG6 is a schematic interaction diagram of a wireless communication method 200 according to an embodiment of the present application. As shown in FIG6 , the method 200 includes at least part of the following:

[0148] S210: The network device sends a first target signal, where the first target signal includes K first signals, where K is a positive integer, for example, K>1.

[0149] Correspondingly, the terminal device receives part or all of the K first signals. For example, the terminal device monitors the first signals through LP-WUR.

[0150] In an embodiment of the present application, the terminal device has a main receiver and an LP-WUR, wherein the power consumption of the LP-WUR is lower than that of the main receiver.

[0151] In some embodiments, the first signal is used to wake up a main receiver of the terminal device. In this case, the first signal is also called an LP-WUS, a wake-up signal, and the first target signal is also called an LP-WUS group.

[0152] In some other embodiments, the first target signal is used to wake up the main receiver of the terminal device. In this case, the first target signal is also called LP-WUS or wake-up signal, and the first signal can be considered as a sub-signal of LP-WUS.

[0153] In some other embodiments, the first signal or the first target signal may also be a signal in a zero-power communication scenario, such as a control signal. For example, a signal sent by a network device to a terminal for paging, scheduling, triggering, communication control and other functions may also be sent and processed using the sending method of an embodiment of the present application. The present application is not limited to this.

[0154] The following is an example in which the first signal is LP-WUS and the first target signal is the LP-WUS group, but the present application is not limited to this. In other scenarios, the names of the first signal and the first target signal can also be adaptively adjusted according to their functions.

[0155] In some embodiments, a network device sends a first target signal, where the first target signal includes K first signals. This may be considered as the network device sending the LP-WUS by aggregating K LP-WUSs. The aggregation of K LP-WUSs may be referred to as bundling of K LP-WUSs or repetition of K LP-WUSs.

[0156] In some embodiments, the network device may be a base station in a cellular communication system, such as a gNB in ​​an NR system, or an AP in a WIFI system, etc., which is not limited in this application.

[0157] In some embodiments, the terminal device may be a terminal device in a cellular communication system, such as a UE in an NR system, or a STA in a WIFI system, or an ambient energy device (AMP device or Ambient device), etc. This application does not limit this.

[0158] In the embodiments of the present application, the ambient energy device is also called an ambient energy Internet of Things device (AMP IoT device or Ambient IoT device), a zero-power device, or a zero-power terminal.

[0159] In some embodiments, the first target signal may be sent to a terminal device, or may be sent to a group of terminal devices, that is, the first target signal or the first signal is used to wake up the main receiver of a terminal device, or to wake up the main receiver of a group of terminal devices.

[0160] In some embodiments, the K first signals are sent according to a first pattern (or structure).

[0161] Optionally, the first pattern may be predefined, or configured by the network device, such as dynamically configured or semi-statically configured.

[0162] In some implementations, the network device may configure a specific pattern of the first pattern.

[0163] In other implementations, the network device may indicate an index of a target pattern among multiple patterns, wherein each pattern corresponds to an index, and the network device may indicate the index of the target pattern. Optionally, the multiple patterns may be predefined, or the network device may be configured in advance.

[0164] Example 1: Design of the first target signal

[0165] Below, the distribution of K LP-WUS is described by taking the first signal as LP-WUS and the first target signal as the LP-WUS group as an example. This application does not limit this. It can also be considered that the first target signal is LP-WUS, then the first signal can be considered as a sub-signal of LP-WUS, and the corresponding distribution of K first signals can be considered as the distribution of K sub-signals.

[0166] It should be understood that the distribution of the K first signals given below is only an example and this application does not limit this. As long as the network device and the terminal device have the same understanding of the pattern of the K first signals, this application is not limited to this.

[0167] Example 1-1: Pattern Design of K First Signals

[0168] In some embodiments, the K first signals are time-division multiplexing (TDM) and / or frequency division multiplexing (FDM).

[0169] That is, the K first signals may be sent using different time domain resources and / or frequency domain resources.

[0170] Case 1: K first signals are sent using the same frequency domain resources.

[0171] For example, the center frequencies and bandwidths of the frequency domain resources used by the K first signals are equal.

[0172] As an example, as shown in FIG. 7A to FIG. 7C , the K first signals use the same frequency domain resources.

[0173] In some embodiments, the K first signals are transmitted continuously in the time domain. In other words, the time domain resources of the K first signals are continuous. As an example, as shown in Figures 7A, 8A, and 9A, the K first signals are transmitted continuously.

[0174] In other embodiments, the K first signals may also be discontinuous in the time domain. In other words, the time domain resources of the K first signals are discontinuous. As an example, as shown in Figures 7B, 7C, 8B, 8C, 9B, and 9C, there is a time interval (denoted as T0) between the K first signals in the time domain.

[0175] Optionally, the time interval T0 may be predefined or configured by the network device, such as dynamically or semi-statically. For example, the network device may configure a specific value for the time interval T0. For another example, the network device may indicate an index of a target time interval among multiple time intervals, where each time interval corresponds to an index, and the network device may indicate the index of the target time interval. Optionally, the multiple time intervals may be predefined or configured in advance by the network device.

[0176] In some implementations, the time intervals between two adjacent first signals among the K first signals may be equal.

[0177] In other implementations, the time intervals between two adjacent first signals among the K first signals may be unequal.

[0178] In some embodiments, no signal is sent between adjacent first signals.

[0179] As an example, as shown in FIG7B , FIG8B , and FIG9B , no signal is sent between adjacent first signals.

[0180] In other embodiments, signals may also be sent between adjacent first signals.

[0181] As an example, as shown in FIG7C , FIG8C , and FIG9C , a third signal exists between K first signals.

[0182] Optionally, the third signal may be used only to separate adjacent first signals and may not carry information. Alternatively, the third signal may also be used to carry information, such as synchronization information (e.g., as a synchronization beacon) or index information of the first signal. Optionally, when the third signal is used as a synchronization signal, it may be considered that the third signal does not carry information.

[0183] In the embodiment of the present application, for the convenience of distinction and explanation, the bandwidth of a first signal is referred to as the LP-WUS bandwidth, the total bandwidth occupied by K first signals is referred to as the LP-WUS group bandwidth or the bandwidth of the first target signal, and the duration of a first signal in the time domain is referred to as an LP-WUS duration.

[0184] In some embodiments, the bandwidth of the third signal is the same as the bandwidth of the first signal, that is, the bandwidth of the third signal is equal to the LP-WUS bandwidth, as shown in FIG. 7C , FIG. 8C , and FIG. 9C .

[0185] For example, the network device may use the same frequency domain resources to send a third signal after each first signal, or use the frequency domain resources of the previous first signal to send a third signal before each first signal, or use the frequency domain resources of the first signal to send a third signal before each first signal, or use fixed frequency domain resources, such as the frequency domain resources of the Xth first signal, or predefined frequency domain resources, or frequency domain resources configured by the network device to send the third signal.

[0186] In some embodiments, the bandwidth of the third signal is greater than the bandwidth of the first signal. For example, the bandwidth of the third signal is equal to the bandwidth of K first signals, that is, the bandwidth of the third signal is equal to the LP-WUS group bandwidth, as shown in FIG. 10C .

[0187] In some embodiments, the duration of a first signal in the time domain (ie, a LP-WUS duration) may be equal to the time interval between adjacent first signals, or may be less than the time interval between two adjacent first signals.

[0188] Case 2: K first signals are sent using different frequency domain resources.

[0189] For example, at least two first signals among the K first signals are sent using different frequency domain resources.

[0190] As an example, as shown in FIG8A to FIG10C , at least two first signals among the K first signals are sent using different frequency domain resources.

[0191] In some embodiments, the different frequency domain resources may be adjacent frequency domain resources, i.e., there is no frequency domain interval between the frequency domain resources, as shown in, for example, Figures 8A to 8C. The transmission of the K first signals in the time domain may refer to the time domain transmission design of the K first signals under the same frequency domain resources in Case 1, and for the sake of brevity, it is not further described here.

[0192] In other embodiments, the different frequency domain resources may be separated by frequency domain intervals, such as shown in FIG9A to FIG9C . The transmission of the K first signals in the time domain may refer to the time domain transmission design of the K first signals under the same frequency domain resources in Case 1, and for the sake of brevity, it is not further described here.

[0193] Optionally, the frequency domain interval is predefined, or configured by the network device, for example, dynamically configured or semi-statically configured.

[0194] In some implementations, the network device may configure a specific value of the frequency domain interval.

[0195] In other implementations, the network device may indicate an index of a target frequency domain interval among a plurality of frequency domain intervals, wherein each frequency domain interval corresponds to an index, and the network device may indicate the index of the target frequency domain interval. Optionally, the plurality of frequency domain intervals may be predefined, or the network device may be configured in advance.

[0196] In some embodiments, two adjacent first signals among the K first signals are sent using different frequency domain resources, or at least two adjacent first signals among the K first signals are sent using different frequency domain resources.

[0197] For example, each time a first signal is sent, the frequency domain resources are switched, as shown in Figures 8A to 9C. Alternatively, there may be two adjacent first signals using the same frequency domain resources, and the K first signals are sent using greater than or equal to 2 frequency domain resources, for example, as shown in Figures 10A to 10C. Taking four first signals as an example, the frequency domain resources used by the four first signals are: frequency domain resource 1, frequency domain resource 2, frequency domain resource 2, and frequency domain resource 1, then when the first first signal and the second first signal are sent, the network device switches the frequency domain resources, when the second and third first signals are sent, the network device does not switch the frequency domain resources, and when the third and fourth first signals are sent, the network device switches the frequency domain resources.

[0198] In some embodiments, M first signals among the K first signals are sent on the same time domain resources, and the M first signals are sent based on different frequency domain resources.

[0199] That is, when M first signals are sent on the same time domain resources, the M first signals may be sent based on different frequency domain resources.

[0200] In some embodiments, the K first signals may be frequency-division multiplexed only, i.e., the K first signals are sent using K different frequency domain resources and use the same time domain resources in the time domain, i.e., they occupy only one LP-WUS duration in the time domain. The K different frequency domain resources may be adjacent, or may have a frequency domain interval, and a signal may or may not be sent in the frequency domain interval. For a specific implementation, reference is made to the relevant implementation of the time domain design of the K first signals under the same frequency domain resources. For the sake of brevity, this description is not repeated here.

[0201] In some embodiments, there is only one first signal on one time domain resource. In this case, the K first signals are time-divided only, or time-divided and frequency-divided, as shown in FIG7A to FIG9C .

[0202] In other embodiments, a time domain resource may also contain multiple first signals. In this case, the K first signals may be frequency-divided only, or time-divided and frequency-divided, as shown in FIG10A to FIG10C .

[0203] It should be understood that in an embodiment of the present application, the time domain resources occupied by the K first signals may be one time domain resource with one first signal, or one time domain resource with multiple first signals, or one first signal may be present on some time domain resources and multiple first signals may be present on other time domain resources. The present application does not limit the specific distribution pattern.

[0204] As shown in FIG11 , in the structure or pattern of K first signals, multiple first signals are sent on some time domain resources, and only one first signal is sent on another part of time domain resources.

[0205] Example 1-2: Design of sending the first target signal

[0206] In some embodiments, the first target signal is sent periodically.

[0207] In some specific embodiments, the transmission timing of the first target signal is periodically distributed in the time domain.

[0208] Figure 12 shows a schematic diagram of a periodically distributed transmission timing of a first target signal. As shown in Figure 12, the transmission timing of the first target signal may be periodically distributed with T as an interval, where T may be the interval between the end position of the transmission timing of the previous first target signal and the start position of the transmission timing of the next first target signal.

[0209] In some embodiments, the period of the transmission opportunity of the first target signal may be predefined, or configured by the network device, such as dynamically or semi-statically. For example, the network device may configure a specific value of the period. For another example, the network device may indicate an index of a target period among multiple candidate periods, where each candidate period corresponds to an index, and the network device may indicate the index of the target period. Alternatively, the multiple candidate periods may be predefined, or configured in advance by the network device.

[0210] In some other specific embodiments, the time domain resources where the transmission opportunities of the first target signal are located are periodically distributed, wherein one or more transmission opportunities of the first target signal are distributed on the time domain resources within a period.

[0211] As an example, the time domain resource where the transmission opportunity of the first target signal is located is shown in Figure 13. The period of the time domain resource is D. Within the period D, the length of the time domain resource occupied by the transmission opportunity of the first target signal is X, where X<=D. One or more transmission opportunities of the first target signal are periodically distributed within the time domain resource of length X.

[0212] Optionally, the period D of the time domain resource may be predefined or configured by the network device, such as dynamically or semi-statically. For example, the network device may configure a specific value of the period D. For another example, the network device may indicate an index of a target period among multiple candidate periods, where each candidate period corresponds to an index, and the network device may indicate the index of the target period. Optionally, the multiple candidate periods may be predefined or configured in advance by the network device.

[0213] Optionally, the length X of the time domain resource may be predefined or configured by the network device, such as dynamically or semi-statically. For example, the network device may configure a specific value of the length X. For another example, the network device may indicate an index of a target length among multiple candidate lengths, where each candidate length corresponds to an index, and the network device may indicate the index of the target length. Optionally, the multiple candidate lengths may be predefined or configured in advance by the network device.

[0214] Optionally, there is a time interval T between the transmission opportunities of two adjacent first signals. This time interval T can be predefined or configured by the network device, such as dynamically or semi-statically. For example, the network device can configure a specific value for the time interval T. For another example, the network device can indicate the index of a target time interval of multiple candidate time intervals, where each candidate time interval corresponds to an index, and the network device can indicate the index of the target time interval. Optionally, the multiple candidate time intervals can be predefined or configured in advance by the network device.

[0215] Optionally, the starting position of the time domain resources occupied by the transmission timing of the first target signal can be aligned with the starting position of a period D, or can also have a certain time offset. Optionally, the time offset can be predefined, or configured by the network device, such as dynamically configured or semi-statically configured. For example, the network device can configure the specific value of the time offset. For another example, the network device can indicate the index of the target time offset of multiple candidate time offsets, wherein each candidate time offset corresponds to an index, and the network device can indicate the index of the target time offset. Optionally, the multiple candidate time offsets can be predefined, or the network device can be configured in advance.

[0216] In some other embodiments, the first target signal is sent based on an event trigger.

[0217] For example, when data arrives at the network device, the network device may send a first target signal.

[0218] In some embodiments, one event is used to trigger the sending of one first target signal, or is used to trigger the sending of multiple first target signals.

[0219] In some specific embodiments, an event may be used to trigger a time domain resource window, in which there are multiple transmission opportunities for the first target signal. Optionally, the multiple transmission opportunities are periodically distributed.

[0220] As shown in Figure 14, an event can be used to trigger the sending of a first target signal, or it can also be used to trigger a time domain resource window, in which there are multiple transmission opportunities for the first target signal. Optionally, the multiple transmission opportunities of the first target signal are periodically distributed.

[0221] In some embodiments, the transmission timing of the first target signal is determined based on a reference signal.

[0222] Optionally, the reference signal may be a paging signal, or may be other downlink signals, such as a synchronization signal.

[0223] In some embodiments, the transmission timing of the first target signal is determined according to the time domain position of the reference signal and the first time interval.

[0224] As an example, the interval between the transmission timing of the first target signal and the time domain position of the reference signal is greater than or equal to the first time interval. Optionally, the interval here can be the time interval between the end position of the transmission timing of the first target signal and the starting position of the reference signal, or the time interval between the starting position of the transmission timing of the first target signal and the starting position of the reference signal, etc., which is not limited in this application.

[0225] As another example, the time domain position of the reference signal and the first time interval are used to determine multiple transmission opportunities of the first target signal.

[0226] In some specific implementations, the time domain position of the reference signal and the first time interval are used to determine a time domain resource window, in which multiple transmission opportunities of the first target signal are distributed. Optionally, the multiple transmission opportunities of the first target signal are periodically distributed.

[0227] As shown in FIG15 , the time domain position of the reference signal and the first time interval are used to determine a time domain resource window, within which multiple transmission opportunities of the first target signal are distributed.

[0228] In some embodiments, the first time interval may be predefined or configured by the network device, such as dynamically or semi-statically. For example, the network device may configure a specific value for the first time interval. For another example, the network device may indicate an index of a target time interval for a plurality of candidate time intervals, where each candidate time interval corresponds to an index, and the network device may indicate the index of the target time interval. Alternatively, the plurality of candidate time intervals may be predefined or configured in advance by the network device.

[0229] Example 2: Reception and processing of the first target signal by the terminal device

[0230] In some embodiments, factors affecting the terminal device's reception performance of the LP-WUS may include, but are not limited to, at least one of the following:

[0231] The coverage capability of the LP-WUS (e.g., coverage range), the capability or type of the terminal device, and the reception mode used by the terminal device.

[0232] Optionally, the coverage capability of the LP-WUS may include the signal strength of the LP-WUS.

[0233] For example, the signal strength of LP-WUS includes but is not limited to at least one of the following:

[0234] Reference Signal Receiving Power (RSRP), Reference Signal Receiving Quality (RSRQ), Signal to Interference plus Noise Ratio (SINR), Received Signal Strength Indication (RSSI).

[0235] For LP-WUS with different coverage capabilities, the terminal device side has different reception performance for LP-WUS. Therefore, the terminal device can adopt an appropriate reception method to receive LP-WUS according to the coverage capability of LP-WUS to ensure the reception performance of LP-WUS.

[0236] For example, for an LP-WUS with a higher RSRP, the terminal device may receive the LP-WUS once; and for an LP-WUS with a lower RSRP, the terminal device may receive multiple LP-WUSs and combine them for processing.

[0237] In some embodiments, a communication system may include multiple terminal devices with different capabilities or types, and the capabilities or types may be divided according to the implementation of the LP-WUR. For example, the implementation of the LP-WUR may be different for terminal devices with different capabilities or types. For example, the LP-WUR of some terminal devices supports monitoring a single LP-WUS for demodulation, decoding, and other reception processing, while the LP-WUR of some terminal devices supports monitoring multiple LP-WUS for combined reception processing, thereby improving the coverage and transmission performance of the LP-WUS.

[0238] For example, terminal devices of different capabilities or types have different reception performance for LP-WUS. Therefore, a suitable reception method can be used to receive LP-WUS according to the capability or type of the terminal device to ensure the reception performance of LP-WUS.

[0239] In some specific embodiments, there are at least two capabilities or types of terminal devices, for example, terminal devices of a first capability (or, a first type) and a second capability (or, a second type), wherein the LP-WUR of the terminal device of the first capability is a first type of LP-WUR, and the LP-WUR of the terminal device of the second capability is a second type of LP-WUR, the power consumption of the first type of LP-WUR is lower than the power consumption of the second type of LP-WUR, and / or the first type of LP-WUR only supports receiving one LP-WUS, and the second type of LP-WUR supports receiving multiple LP-WUS.

[0240] Optionally, the first type of LP-WUR only needs to receive one LP-WUS in the LP-WUS group to complete the solution; then, the terminal device with the first capability can receive the first LP-WUS in the LP-WUS group. The first LP-WUS can be any LP-WUS in the LP-WUS group, or can be determined according to a predefined rule (e.g., a predefined Yth LP-WUS), or determined according to the configuration of the network device.

[0241] In some scenarios, if the LP-WUS group is transmitted in frequency division and only occupies the time length of one LP-WUS in the time domain, the first type of LP-WUR can only receive part of the bandwidth corresponding to the LP-WUS group or the LP-WUS signal in one LP-WUS bandwidth, where the LP-WUS bandwidth is the bandwidth of one LP-WUS signal.

[0242] Optionally, the second type of LP-WUR can support receiving multiple LP-WUS in the LP-WUS group for combined processing, thereby increasing the data transmission performance and coverage of the LP-WUS. For example, the second type of LP-WUR can always receive multiple LP-WUS, or determine whether to receive one LP-WUS or multiple LP-WUS based on auxiliary information (such as the coverage capability of the LP-WUS or the configuration information of the network device); when receiving multiple LP-WUS, it can receive all LP-WUS in the entire LP-WUS group, or receive some LP-WUS in the LP-WUS group.

[0243] In some scenarios, if the LP-WUS group is sent in frequency division and only occupies the time length of one LP-WUS in the time domain, the second type of LP-WUR can receive the LP-WUS signal on the entire bandwidth corresponding to the LP-WUS group and merge the received multiple LP-WUS.

[0244] In some embodiments, for a terminal device with the first capability, LP-WUS may be received once, and for a terminal device with the second capability, multiple LP-WUS may be received and combined for processing.

[0245] In some embodiments, the receiving mode adopted by the terminal device may refer to the reception processing method of the LP-WUR of the terminal device to the LP-WUS, wherein different receiving modes may correspond to different power consumption.

[0246] In some embodiments, the LP-WUR of the terminal device can support multiple reception modes, for example, a first reception mode and a second reception mode, wherein the power consumption of the first reception mode is lower than the power consumption of the second reception mode.

[0247] For example, in the first receiving mode, the LP-WUR of the terminal device receives only one LP-WUS in the LP-WUS group, and in the second receiving mode, the LP-WUR of the terminal device receives multiple LP-WUS in the LP-WUS group and performs merge processing.

[0248] In some embodiments, the LP-WUR of the terminal device of the second capability or the second type can support receiving multiple LP-WUS, then the LP-WUR can support the first receiving mode and the second receiving mode, and the terminal device can determine whether to adopt the first receiving mode or the second receiving mode based on auxiliary information (such as the coverage capability of the LP-WUS or the configuration information of the network device, etc.).

[0249] In some embodiments, the terminal device may determine the reception mode to use based on at least one of the coverage capability of the LP-WUS, configuration information of the network device, and the location of the terminal device. The configuration information of the network device may be used to configure the reception mode used by the terminal device to receive the LP-WUS.

[0250] In some specific embodiments, the terminal device may determine whether to adopt the first receiving mode or the second receiving mode according to the signal strength and the signal strength threshold of the LP-WUS.

[0251] For example, when the signal strength of the first signal and the signal strength threshold meet a first preset condition, the first receiving mode is adopted; when the signal strength of the first signal and the signal strength threshold meet a second preset condition, the second receiving mode is adopted.

[0252] Optionally, if the signal strength of the first signal and the signal strength threshold meet the first preset condition, it can be considered that the coverage capability of the first signal is strong, or the coverage range of the first signal is large, or the terminal device is in the central coverage area (i.e., the distance between the terminal device and the network device is close). In this case, using the first receiving mode to receive LP-WUS is beneficial to reducing the power consumption of the terminal device.

[0253] In some embodiments, the signal strength of the first signal and the signal strength threshold satisfying the first preset condition may include:

[0254] The signal strength of the first signal is greater than the signal strength threshold; or

[0255] The signal strength of the first signal is greater than or equal to the signal strength threshold.

[0256] Optionally, if the signal strength of the first signal and the signal strength threshold meet the second preset condition, it can be considered that the coverage capability of the first signal is weak, or the coverage range of the first signal is small, or the terminal device is at the edge of the coverage area (i.e., the distance between the terminal device and the network device is far). In this case, using the second receiving mode to receive the LP-WUS is beneficial to improving the coverage range and transmission performance of the LP-WUS.

[0257] In some embodiments, the signal strength of the first signal and the signal strength threshold satisfying the second preset condition may include:

[0258] The signal strength of the first signal is less than or equal to the signal strength threshold; or

[0259] The signal strength of the first signal is less than the signal strength threshold.

[0260] Optionally, the signal strength threshold may be predefined or configured by the network device.

[0261] In other specific embodiments, if the network device configures the terminal device to adopt the first receiving mode, the terminal device adopts the first receiving mode; if the network device configures the terminal device to adopt the second receiving mode, the terminal device adopts the second receiving mode.

[0262] In some embodiments of the present application, the method 200 further includes:

[0263] The terminal device determines a receiving mode of the first target signal according to the first information;

[0264] The first information includes at least one of the following:

[0265] The capabilities of the terminal device, the receiving mode of the terminal device, the coverage capability of the first target signal, and the configuration information of the network device.

[0266] In some embodiments, the configuration information of the network device can be used to configure a receiving method used by the terminal device to receive the second target signal. For example, the terminal device can be configured to receive one first signal among the first target signals, or multiple first signals. More specifically, the terminal device can be configured to receive which first signal or signals among the first target signals.

[0267] In some specific embodiments, when the first condition is met, the terminal device receives a first signal among the first target signals;

[0268] The first condition includes at least one of the following:

[0269] The terminal device is a terminal device of a first capability or a first type;

[0270] The terminal device adopts a first receiving mode;

[0271] The signal strength of the first signal and the signal strength threshold meet a first preset condition.

[0272] In some other specific embodiments, when the second condition is met, the terminal device receives a plurality of first signals in the first target signal;

[0273] The second condition includes at least one of the following:

[0274] The terminal device is a terminal device of the second capability or the second type;

[0275] The terminal device adopts a second receiving mode;

[0276] The signal strength and the signal strength threshold of the first signal meet a second preset condition.

[0277] In summary, the network device can send the wake-up signal in the form of an LP-WUS group, for example, by periodically sending the first target signal or sending the first target signal based on an event trigger, thereby improving the coverage performance and transmission performance of the wake-up signal.

[0278] Correspondingly, the terminal device can adopt a suitable receiving method to receive and process the LP-WUS, which is conducive to taking into account both the power consumption of the terminal device and the receiving performance of the LP-WUS.

[0279] Embodiment 2: Sending a wake-up signal based on the LP-WUS group cascade mode.

[0280] For example, the next level LP-WUS group is obtained from the previous level LP-WUS group.

[0281] In some embodiments of the present application, the method 200 further includes:

[0282] The network device sends a second target signal, where the second target signal is obtained based on L first target signals, where L is a positive integer, for example, L=1, or L>1.

[0283] In some embodiments, the first target signal may be considered to be a carrier signal of the second target signal, or in other words, a previous-level wake-up signal.

[0284] For example, the network device modulates L first target signals to obtain a second target signal.

[0285] In some embodiments, the information carried in the first target signal and the second target signal may be the same, or may be different.

[0286] For example, the first target signal is used to carry wake-up information for a terminal device, and the second target signal is used to carry wake-up information for a terminal group.

[0287] It should be understood that in an embodiment of the present application, when the network device sends a wake-up signal in a cascade manner, the first target signal and the second target signal can be any adjacent two-level wake-up signals in a multi-level wake-up signal. For example, the first target signal can be the k-th level wake-up signal in the multi-level wake-up signal, and the second target signal is the k+1-th level wake-up signal in the multi-level wake-up, where k=1, 2,…, K-1, and K is the total number of levels.

[0288] In some embodiments, the second target signal is obtained from L first target signals and may include:

[0289] The second target signal is obtained based on a first target signal, as shown in (a) of Figure 16. The distribution of the K first signals in the first target signal can refer to the relevant description in Example 1, which is not repeated here for the sake of brevity.

[0290] Optionally, in this embodiment, the second target signal may include K second signals, and the distribution of the K second signals refers to the distribution of the K first signals in Example 1, that is, the K second signals may be time division multiplexing and / or frequency division multiplexing. The specific implementation refers to the relevant description in Example 1, and for the sake of brevity, it will not be repeated here.

[0291] In some other embodiments, the second target signal is obtained from L first target signals and may include:

[0292] The second target signal is obtained based on the multiple first target signals, as shown in (b) of FIG16 .

[0293] It should be understood that (b) in Figure 16 only takes the time division multiplexing of the multiple first target signals as an example, but the present application is not limited to this. The multiple first target signals can be time division multiplexed and / or frequency division multiplexed. The distribution of the multiple first target signals can refer to the relevant description of the distribution of K first signals in Example 1, that is, replacing the first signal in Example 1 with the first target signal can obtain the specific implementation of the distribution of the multiple first target signals. For the sake of brevity, it will not be repeated here.

[0294] Optionally, in this embodiment, the second target signal may include K*L second signals, and the distribution of the K*L second signals refers to the distribution of the K first signals in Example 1, that is, the K*L second signals may be time division multiplexing and / or frequency division multiplexing. The specific implementation refers to the relevant description in Example 1, and for the sake of brevity, it will not be repeated here.

[0295] In a specific embodiment, L>1, the L first target signals in the second target signal are only time-division multiplexed, for example, using the same frequency domain resources, or, the L first target signals are only frequency-division multiplexed, then the L first target signals occupy the time length of one first target signal in the time domain.

[0296] In some embodiments, the second target signal and the first target signal are modulated in different ways.

[0297] For example, the first target signal is obtained by modulating P third target signals using a first modulation method, and the second target signal is obtained by modulating L first target signals using a second modulation method, wherein the third target signal is the carrier signal of the first target signal, the first modulation method and the second modulation method are different, and P is a positive integer.

[0298] Optionally, the complexity of the second modulation method is lower than the complexity of the first modulation method, that is, the complexity of the terminal device receiving and processing the second target signal is lower than the complexity of the terminal device receiving and processing the first target signal.

[0299] Optionally, the second modulation mode may be on-off keying (OOK), and the first modulation mode may be phase shift keying (PSK), amplitude shift keying (ASK) or frequency shift keying (FSK), etc.

[0300] In other embodiments, the modulation schemes used by the second target signal and the first target signal may also be the same, for example, both use OOK modulation.

[0301] In some embodiments, the second target signal and the first target signal are encoded in different ways, or they may be the same, for example, both use Manchester encoding.

[0302] In some embodiments, the second target signal and the first target signal have different symbol lengths.

[0303] For example, the symbol length of the first target signal is smaller than the symbol length of the second target signal. As a specific example, the length of each symbol in the second target signal is equal to an integer multiple of the time length of the first target signal, as shown in FIG17 .

[0304] In some embodiments of the present application, the method 200 further includes:

[0305] The terminal device determines a receiving mode of the second target signal according to the second information;

[0306] The second information includes at least one of the following:

[0307] The capabilities of the terminal device, the receiving mode of the terminal device, the coverage capability of the second target signal, and the configuration information of the network device.

[0308] In some embodiments, the configuration information of the network device can be used to configure a receiving method used by the terminal device to receive the second target signal. For example, the terminal device can be configured to receive one of the second target signals, or multiple second signals. More specifically, the terminal device can be configured to receive which second signal or signals among the second target signals.

[0309] In some specific embodiments, when the third condition is met, the terminal device receives a second signal among the second target signals;

[0310] The third condition includes at least one of the following:

[0311] The terminal device is a terminal device of a first capability or a first type;

[0312] The terminal device adopts a first receiving mode;

[0313] The signal strength of the second signal and the signal strength threshold meet a third preset condition.

[0314] In some other specific embodiments, when the fourth condition is met, the terminal device receives a plurality of second signals in the second target signal;

[0315] The fourth condition includes at least one of the following:

[0316] The terminal device is a terminal device of the second capability or the second type;

[0317] The terminal device adopts a second receiving mode;

[0318] The signal strength and the signal strength threshold of the second signal meet a fourth preset condition.

[0319] In some embodiments, the signal strength of the second signal and the signal strength threshold satisfying the third preset condition may include:

[0320] The signal strength of the second signal is greater than the signal strength threshold; or

[0321] The signal strength of the second signal is greater than or equal to the signal strength threshold.

[0322] In some embodiments, the signal strength of the second signal and the signal strength threshold satisfying the fourth preset condition may include:

[0323] The signal strength of the second signal is less than or equal to the signal strength threshold; or

[0324] The signal strength of the second signal is less than the signal strength threshold.

[0325] Optionally, the signal strength threshold may be predefined or configured by the network device. The signal strength threshold may be the same as the signal strength threshold in Example 1, or may be different.

[0326] In the scenario of this embodiment 2, the terminal device can only receive the second target signal, or it can also receive both the first target signal and the second target signal. For example, after completing demodulation, decoding and other processing on the second target signal, it further performs demodulation, decoding and other processing on the first target signal.

[0327] In some embodiments of the present application, the method 200 further includes:

[0328] The network device sends first configuration information to the terminal device, where the first configuration information is used by the terminal device to receive a target signal (or a wake-up signal), and the target signal is used to wake up a main receiver of the terminal device.

[0329] In some embodiments, the target signal may include a first target signal and / or a second target signal.

[0330] In some embodiments, the first configuration information is used to configure at least one of the following information:

[0331] The number of the K first signals, that is, the number of LP-WUSs in an LP-WUS group;

[0332] The number M of first signals frequency-division multiplexed in the frequency domain among the K first signals;

[0333] The number N of transmission opportunities of the K first signals in the time domain, or in other words, the number N of LP-WUS durations occupied by the K first signals in the time domain;

[0334] A frequency domain interval between two adjacent first signals frequency-division multiplexed in the frequency domain among the K first signals;

[0335] A time interval between two adjacent first signals time-division multiplexed in the time domain among the K first signals;

[0336] patterns of the K first signals;

[0337] A threshold for the terminal device to switch the receiving mode;

[0338] spatial information corresponding to the K first signals;

[0339] The number L of first target signals on which the second target signal is based is obtained.

[0340] It should be understood that the parameters configured in the first configuration information can be configured through one signaling, or can be configured through different signaling, can be dynamically configured, or can be semi-statically configured, for example, through RRC signaling.

[0341] In some embodiments, the number M of first signals frequency-division multiplexed in the frequency domain among the K first signals and the number NN of LP-WUS durations occupied by the K first signals in the time domain can be used to determine the number of LP-WUSs in an LP-WUS group, for example, K=M*N.

[0342] In some embodiments, the threshold for the terminal device to switch the receiving mode may include the signal quality threshold mentioned above.

[0343] In some embodiments, the spatial information corresponding to the K first signals (i.e., the first target signals) can be used to indicate a quasi-co-located (QCL) relationship between the first target signal and the reference signal, for example, through a transmission configuration indicator (TCI) status indication.

[0344] Optionally, the reference signal can be an existing signal or channel in the communication system, such as a channel state information reference signal (CSI-RS), a synchronization signal block (SSB), a physical downlink control channel (PDCCH), etc.

[0345] In some embodiments, the spatial information corresponding to the first target signal may include beam information corresponding to the first target signal.

[0346] In some embodiments, when the first configuration information does not include the number K, the number K may be predefined.

[0347] In some embodiments, when the first configuration information does not include the number M, the number M may be predefined.

[0348] In some embodiments, when the first configuration information does not include the number N, the number M may be predefined.

[0349] In some embodiments, when the first configuration information does not include the number L, the number L may be predefined.

[0350] In some embodiments, when the first configuration information does not include a frequency domain interval between two adjacent first signals, the frequency domain interval may be predefined.

[0351] In some embodiments, when the first configuration information does not include the time interval between two adjacent first signals, the time interval may be predefined.

[0352] In some embodiments, when the first configuration information does not include a pattern of the K first signals, the pattern may be predefined.

[0353] In some embodiments, when the first configuration information does not include a threshold for the terminal device to switch the receiving mode, the threshold for the terminal device to switch the receiving mode may be predefined.

[0354] In some embodiments, when the first configuration information does not include spatial information corresponding to the K first signals, the spatial information corresponding to the K first signals may be predefined or determined according to a preset rule.

[0355] For example, the correspondence between LP-WUS groups and reference signals on different time domain resources, frequency domain resources, or code domain resources is predefined. In this way, the spatial information of the LP-WUS group can be determined based on the time domain resources, frequency domain resources, or code domain resources of the LP-WUS group.

[0356] In summary, the embodiments of the present application provide a method for sending a wake-up signal. The network device can use time division and / or frequency division to send the wake-up signal in units of LP-WUS groups, or it can use a cascaded manner to send the wake-up signal. It can adapt to terminal devices of various capabilities or types, as well as different receiving modes of terminal devices, thereby improving the coverage and transmission performance of the wake-up signal.

[0357] Correspondingly, the terminal device can determine the LP-WUS reception mode based on at least one of its own capabilities, the coverage capability of the LP-WUS, the LP-WUR reception mode, and the configuration information of the network device.

[0358] For example, the LP-WUR of some terminals (such as terminals with the first capability) adopts a low-level (lower power consumption or lower complexity) receiving and processing method to receive and process the LP-WUS, such as only receiving one LP-WUS in the LP-WUS group, or only receiving the first target signal. Some terminals (such as terminals with the second capability) adopt a high-level (higher power consumption or higher complexity) receiving and processing method to receive and process the LP-WUS, such as receiving multiple LP-WUS in the LP-WUS group for combined processing, or receiving LP-WUS in multiple LP-WUS groups in a cascaded LP-WUS group.

[0359] For example, the terminal device can determine whether to adopt a low-level (lower power consumption or lower complexity) receiving and processing method or a high-level (higher power consumption or higher complexity) receiving and processing method based on the coverage capability of the LP-WUS to ensure the receiving performance of the LP-WUS with different coverage capabilities.
