[0059] To facilitate understanding of the technical solutions of the embodiments of the present application, the relevant technologies of the present application are explained.

[0060] 1. Zero-power communication

[0061] The key technologies of zero-power communication include energy harvesting, backscatter communication and low-power technology.

[0062] 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 terminal (such as an electronic tag). The network device is used to send wireless power supply signals, downlink communication signals, and receive backscattered signals from the zero-power terminal to the zero-power terminal. A basic zero-power terminal includes an energy collection module, a backscatter communication module, and a low-power computing module. In addition, the zero-power terminal 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.

[0063] 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 terminal and implement backscatter communication. After obtaining energy, the zero-power terminal 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 terminal itself (such as an identity or pre-written information, such as the product's production date, brand, manufacturer, etc.). The zero-power terminal can also be loaded with various sensors, so that the data collected by various sensors can be reported based on the zero-power mechanism.

[0064] The following describes the key technologies in zero-power communication.

[0065] 1. RF Power Harvesting

[0066] As shown in Figure 3, the RF energy harvesting module uses the principle of electromagnetic induction to collect electromagnetic wave energy from space, thereby obtaining the energy required to operate the zero-power terminal. For example, it is used to drive low-power demodulation and modulation modules, sensors, and memory reading. Therefore, the zero-power terminal does not require traditional batteries.

[0067] 2. Back Scattering

[0068] As shown in Figure 4, a zero-power terminal 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 terminal's oscillator circuit according to the data stream's rhythm, causing parameters such as the zero-power terminal'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 switched 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). This modulation and transmission of the signal is achieved by adjusting the amplitude of the zero-power terminal's backscattered signal. Similarly, in capacitive load modulation, the switching of the capacitor changes the circuit's resonant frequency, enabling frequency-shifted keying (FSK). This modulation and transmission of the signal is achieved by adjusting the operating frequency of the zero-power terminal's backscattered signal.

[0069] It can be seen that the zero-power terminal uses load modulation to modulate the incoming signal, thereby realizing the backscatter communication process. Therefore, the zero-power terminal has significant advantages:

[0070] (1) It does not actively transmit signals, so it does not require complex RF links, such as PA, RF filters, etc.

[0071] (2) There is no need to actively generate high-frequency signals, so no high-frequency crystal oscillator is required;

[0072] (3) With the help of backscatter communication, terminal signal transmission does not need to consume the terminal's own energy.

[0073] 3. Coding technology

[0074] Data transmitted by zero-power terminals can use various codes to represent binary "1" and "0." 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 0 and 1.

[0075] Due to its significant advantages such as extremely low cost, zero power consumption, and small size, zero-power communication can be widely used in various industries, such as logistics for vertical industries, smart warehousing, smart agriculture, energy and electricity, industrial Internet, etc.; it can also be applied to personal applications such as smart wearables and smart homes.

[0076] In some scenarios, based on their energy sources and usage, zero-power terminals can be categorized into the following types:

[0077] 1. Passive zero-power terminal

[0078] Zero-power terminals (such as electronic tags in RFID systems) do not require internal batteries. When a zero-power terminal approaches 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 terminal's antenna generates an induced current through electromagnetic induction, which drives the low-power chip circuitry in the zero-power terminal. This enables forward link signal demodulation and reverse link (or reflection link) signal modulation. For backscatter links, the zero-power terminal uses backscattering to transmit signals.

[0079] It can be seen that the passive zero-power terminal does not require a built-in battery to drive either the forward link or the reverse link, and is a true zero-power terminal.

[0080] Passive zero-power terminals 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.

[0081] 2. Semi-passive zero-power terminal

[0082] Semi-passive zero-power terminals do not have conventional batteries themselves, but instead use RF energy harvesting modules to harvest radio wave energy and store it in an energy storage unit (such as a capacitor). This energy is then used to power the low-power chip circuitry in the zero-power terminal, performing tasks such as demodulating forward link signals and modulating reverse link signals. For backscatter links, the zero-power terminal uses backscattering to transmit signals.

[0083] It can be seen that the semi-passive zero-power terminal does not require a built-in battery to drive either the forward link or the reverse link. Although energy stored in capacitors is used in operation, the energy comes from the radio energy collected by the energy harvesting module. Therefore, it is also a true zero-power terminal.

[0084] Semi-passive zero-power consumption terminals inherit many advantages of passive zero-power consumption terminals, so they have many advantages such as small size, light weight, very low price, and long service life.

[0085] 3. Active zero-power terminal

[0086] In some scenarios, zero-power terminals can also be active zero-power terminals, which can have built-in batteries. The batteries power the low-power chip circuits in the zero-power terminal, which perform tasks such as demodulating forward link signals and modulating reverse link signals. However, for backscatter links, zero-power terminals 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.

[0087] 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.

[0088] In some scenarios, zero-power devices can be categorized as follows based on transmitter type:

[0089] 1) Zero-power devices based on backscattering

[0090] 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.

[0091] 2) Zero-power devices based on active transmitters

[0092] 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.

[0093] 3) Zero-power devices with both backscatter transmitters and active transmitters

[0094] 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.

[0095] 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:

[0096] 1. Harsh communication environment

[0097] 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.

[0098] 2. Demand for extremely small terminal form factors

[0099] 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.

[0100] 3. Extremely low-cost IoT communication requirements

[0101] 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.

[0102] 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.

[0103] 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.

[0104] Ambient IoT can be used in at least four scenarios:

[0105] 1. Object recognition, such as logistics, production line product management, and supply chain management;

[0106] 2. Environmental monitoring, such as temperature, humidity, and harmful gas monitoring of the working environment and natural environment;

[0107] 3. Positioning, such as indoor positioning, intelligent object search, production line item positioning, etc.

[0108] 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).

[0109] In order to further save power in terminal equipment, it is considered to introduce a wake-up receiver (WUR) to receive the wake-up signal. The wake-up receiver has the characteristics of extremely low cost, extremely low complexity and extremely low power consumption. It mainly receives the wake-up signal (WUS) based on envelope detection. Therefore, the WUS received by the wake-up receiver is different from the modulation method and waveform of the signal carried by the physical downlink control channel (PDCCH). The wake-up signal is mainly an envelope signal modulated by amplitude shift keying (ASK) of the carrier signal. The demodulation of the envelope signal is also mainly based on the energy provided by the wireless radio frequency signal to drive the low-power circuit, so it can be passive. The wake-up receiver can also be powered by the terminal. Regardless of the power supply method, the wake-up receiver greatly reduces power consumption compared to the traditional receiver of the UE. The wake-up receiver can be combined with the UE as an additional module of the UE receiver, or it can be used as a wake-up function module of a UE alone.

[0110] The block diagram of the receiver system based on the wake-up signal is shown in FIG6 . The wake-up receiver receives the wake-up signal and can instruct the UE to turn on the main receiver if necessary. Otherwise, the UE's main receiver can be turned off.

[0111] In some scenarios, wake-up radio (WUR) signals are used to achieve energy saving of devices. The WUR AP notifies the WUR non-AP STA of energy saving operations through the WUR wake-up frame. The wake-up frame is carried in the WUR physical layer Protocol Data Unit (PPDU) frame. As shown in Figure 7, a WUR PPDU frame contains three parts: legacy preamble, WUR synchronization (WUR-Sync) and WUR data (WUR-Data). Among them, the legacy preamble is used to protect the WUR-Sync and WUR-Data parts. It is a non-WUR part retained for compatibility reasons. It uses traditional orthogonal frequency-division multiplexing (OFDM) modulation and 20MHz bandwidth. WUR-Sync is used to help identify and demodulate the WUR-data part, and the WUR-Data part is used to carry the WUR PSDU.

[0112] The WUR-Sync and WUR-data sections use on-off keying (OOK) modulation and 4 MHz of the 20 MHz channel bandwidth. OOK modulation modulates the carrier signal's amplitude to non-zero and zero values, corresponding to "on" and "off," respectively, to represent information bits. OOK is also known as binary amplitude shift keying (2ASK). Figure 8 shows the principle diagram of OOK modulation. The WUR-data section carries user information, which is encoded and modulated using OOK to form MC-OOK symbols of the appropriate length.

[0113] The above-mentioned OOK signal is generated by multi-carrier (MC), so the OOK signal is called MC-OOK signal. The MC-OOK signal can be an OOK signal generated by multi-carrier modulation such as OFDM modulation, which can maintain good compatibility with the OFDM system and reduce the transmitter complexity introduced by the implementation of the WUR signal. Figure 9 is a schematic diagram of the MC-OOK signal generated by multi-carrier. By mapping the corresponding amplitude values ​​to multiple subcarriers in the frequency domain, the waveform of the time domain signal converted to the inverse discrete Fourier transform (IDFT) is similar to the waveform formed by ASK modulation, wherein bit 1 is represented by the high level of the signal and bit 0 is represented by the low level of the signal.

[0114] In some scenarios, the following MC-ASK waveform generation method is considered, where K represents the number of IDFT points, and N is the number of subcarriers used to transmit the WUS signal.

[0115] The first MC-ASK waveform generation method (denoted as OOK-1): Each OFDM symbol carries 1 bit. The subcarrier carrying the WUS signal is modulated and IDFT-ed, and the corresponding output OOK signal is 1. The subcarrier carrying the WUS signal is zero-power, and the corresponding output OOK signal is 0. Figure 10 shows a schematic diagram of the WUS signal generation process based on the OOK-1 waveform generation method.

[0116] The second MC-ASK waveform generation method (denoted as OOK-2): Each OFDM symbol carries M bits in the frequency domain. The N subcarriers carrying the AMP signal are divided into M segments, each of which carries 1 bit of information. In each segment, when all subcarriers are modulated, the corresponding output OOK signal is 1; when all subcarriers are at zero power, the corresponding output OOK signal is 0. Figure 11 shows a schematic diagram of the AMP signal generation process based on the OOK-2 waveform generation method when M = 2.

[0117] The third MC-ASK waveform generation method (denoted as OOK-3) uses a single OFDM symbol to carry one bit, and the N subcarriers carrying the AMP signal are divided into M segments. Within each of the M segments, when one subcarrier in each segment is modulated and the other subcarriers are at zero power, the corresponding output OOK signal is 1. When all subcarriers in all segments are at zero power, the corresponding output OOK signal is 0.

[0118] The fourth MC-ASK waveform generation method (denoted as OOK-4): Each OFDM symbol carries M bits in the time domain. The N subcarriers carrying the AMP signal are generated through DFT, with S sampling points representing the M bits. These S sampling points are transformed through DFT to form S subcarriers. Furthermore, the S subcarriers are truncated and other processing is performed to form N subcarriers, which are then transformed through IDFT to generate the OOK signal. Figure 12 shows a schematic diagram of the AMP signal generation process based on the OOK-3 waveform generation method when M = 4.

[0119] In addition to the MC-ASK waveform, LP-WUS can also use the MC-FSK waveform. For example, the following MC-FSK waveform generation method can be used:

[0120] The first MC-FSK waveform generation method (denoted as FSK-1): N subcarriers carrying AMP signals are divided into M pairs of segments. In each OFDM symbol, one segment in each pair of segments is modulated and the other segment is zero power.

[0121] The first MC-FSK waveform generation method (denoted as FSK-2): The N subcarriers carrying the AMP signal are divided into 2 M segments, in each OFDM symbol, 2 M One of the segments is modulated and the other segments are at zero power.

[0122] The bit rates, resource overhead, and performance of the above-mentioned MC-ASK and MC-FSK signal generation methods are different. In practical applications, the transmitting device can flexibly select one of the multiple signal generation methods based on specific needs. For the receiving device, how to receive the signal is an urgent problem that needs to be solved.

[0169] For example, the receiving end device may know in advance the number and / or positions of subcarriers occupied by the first signal, and the receiving end device may receive the first signal at the corresponding resource position.

[0170] In some embodiments, the receiving device may determine the resource location of the target signal based on the pre-known resource location of the first signal and the association between the resource location of the first signal and the resource location of the target signal.

[0171] Case 2: The receiving device can know the resource location of the target signal in advance

[0172] For example, the resource location of the target signal is predefined, or preconfigured by the transmitting device.

[0173] Optionally, the resource location of the target signal may include: the number and / or location of subcarriers occupied by the target signal.

[0182] The frequency domain resources occupied by the target signal are the same as the frequency domain resources occupied by the first signal, or the frequency domain resources occupied by the first signal are a part of the frequency domain resources occupied by the target signal.

[0183] In some embodiments, the frequency domain resources of the first signal may include the subcarriers occupied by the first signal, or the subcarriers used to carry the first signal, and the frequency domain resources of the target signal may include the subcarriers occupied by the target signal, or the subcarriers used to carry the target signal.

[0184] The following describes the association relationship between the frequency domain resources of the first signal and the frequency domain resources of the target signal in combination with Examples 1-1 to 1-3.

[0185] Example 1-1: The subcarrier used to carry the first signal is the same as the subcarrier used to carry the target signal.

[0186] That is, no matter which signal generation method is adopted for the target signal, the subcarriers occupied by the first signal and the subcarriers occupied by the target signal are the same.

[0187] In some specific embodiments, as shown in FIG14 , the target signal is generated based on the first MC-ASK waveform generation method, and the target signal is carried by N subcarriers (i.e., SC#0 to SC#N-1), and the subcarriers occupied by the first signal are the same as the subcarriers occupied by the target signal.

[0188] In other specific embodiments, as shown in Figure 15, the target signal is generated based on the second MC-ASK waveform generation method, and the target signal is carried by N subcarriers (i.e., SC#0 to SC#N-1). The N subcarriers are divided into 2 (i.e., M=2) segments, and the subcarriers occupied by the first signal are the same as the subcarriers occupied by the target signal.

[0189] Example 1-2: The subcarrier used to carry the first signal is the same as the subcarrier corresponding to one or more segments of the N segments, and the N segments are all segments corresponding to the N subcarriers used to carry the target signal, where N is a positive integer.

[0190] In this embodiment 1-2, the N subcarriers used to carry the target signal are divided into M segments, and the first signal occupies subcarriers corresponding to X segments of the M segments, where X is a positive integer and X<M.

[0191] Optionally, the X segments may be the first X segments of the M segments, or the last X segments, or the middle X segments.

[0192] Optionally, the positions of the X segments in the M segments may be predefined or configured by the transmitting end device.

[0193] Optionally, the association relationship between the resource location of the first signal and the resource location of the target signal may include:

[0194] The position information of the X segments among the M segments.

[0195] In some specific embodiments, as shown in Figure 16, the target signal is generated based on the second MC-ASK waveform generation method, and the target signal is carried by N subcarriers (i.e., SC#0 to SC#N-1). The N subcarriers are divided into 2 (i.e., M=2) segments. The first signal occupies the subcarrier corresponding to the first segment of the two segments (i.e., the segment corresponding to m=0), or it can also occupy the subcarrier corresponding to the second segment of the two segments (i.e., the segment corresponding to m=1), or the first signal can also be sent on the subcarriers corresponding to the two segments.

[0196] In other specific embodiments, as shown in Figure 17, the target signal is generated based on the second MC-ASK waveform generation method, and the target signal is carried by N subcarriers (i.e., SC#0 to SC#N-1), and the N subcarriers are divided into 4 (i.e., M=4) segments. The first signal occupies the subcarriers corresponding to the first two segments of the 4 segments (i.e., the segments corresponding to m=0 and m=1), or it can also occupy the subcarriers corresponding to the last two segments of the 4 segments (i.e., the segments corresponding to m=2 and m=3), or it can also occupy the subcarriers corresponding to the middle two segments of the 4 segments (i.e., the segments corresponding to m=1 and m=2).

[0197] Example 1-3: The subcarrier used to carry the first signal is the same as Y subcarriers among the N subcarriers used to carry the target signal, where N is a positive integer, Y is a positive integer, and Y<N.

[0198] That is, in the embodiments 1-3, the subcarriers corresponding to the first signal are some of the N subcarriers corresponding to the target signal. The subcarriers may be independent of the number of segments of the N subcarriers corresponding to the target signal.

[0199] Optionally, the positions of the Y subcarriers in the N subcarriers may be predefined, or may be configured by the transmitting end device.

[0200] In some embodiments, the Y subcarriers are the center Y subcarriers of the N subcarriers, or the first Y subcarriers, or the last Y subcarriers of the N subcarriers.

[0201] Optionally, the association relationship between the resource location of the first signal and the resource location of the target signal may include:

[0202] Position information of the Y subcarriers among the N subcarriers.

[0203] In some specific embodiments, as shown in FIG18 , the target signal is generated based on a first MC-ASK waveform generation method, the target signal is carried by N subcarriers (i.e., SC#0 to SC#N-1), and the first signal occupies part of the N subcarriers.

[0204] In other specific embodiments, as shown in Figure 19, the target signal is generated based on the second MC-ASK waveform generation method, and the target signal is carried by N subcarriers (i.e., SC#0 to SC#N-1). The N subcarriers are divided into 2 (i.e., M=2) segments, and the first signal occupies part of the N subcarriers.

[0205] Embodiment 2: The resource location of the first signal and the resource location of the target signal have no correlation relationship, or in other words, the resource location of the first signal and the resource location of the target signal are independent.

[0206] In this embodiment 2, the receiving end device can know the resource location of the first signal in advance, and the receiving end device can receive the first signal at the corresponding resource location.

[0207] For example, the resource location of the first signal is predefined, or preconfigured by the transmitting device.

[0208] In some embodiments, the receiving device can receive the first signal based on the resource location of the first signal known in advance. The first signal can indicate the resource location of the target signal, and the receiving device can obtain the resource location of the target signal based on the indication in the first signal.

[0209] In some embodiments, the resource location of the first signal and the resource location of the target signal have no correlation relationship, which may include:

[0210] The subcarrier used to carry the first signal and the subcarrier used to carry the target signal do not overlap, or partially overlap.

[0211] In some specific embodiments, as shown in FIG20 , the target signal is generated based on the first MC-ASK waveform generation method, and the target signal is carried by N subcarriers (i.e., SC#0 to SC#N-1), and the subcarriers occupied by the first signal and the subcarriers occupied by the target signal do not overlap.

[0212] In other specific embodiments, as shown in Figure 21, the target signal is generated based on the first MC-ASK waveform generation method, and the target signal is carried by N subcarriers (i.e., SC#0 to SC#N-1), and the subcarriers occupied by the first signal and the subcarriers occupied by the target signal partially overlap.

[0213] In some embodiments of the present application, as shown in Figures 14 to 21, the target signal and other signals are multiplexed within the frequency band, where the other signals may refer to existing signals or channels in the communication system, or legacy signals or channels, for example, legacy signals or channels in the NR system, or existing signals or frames in the WIFI system.

[0214] In some embodiments, the signal generation method of the first signal can be an MC-ASK waveform generation method, such as the aforementioned first MC-ASK waveform generation method, the second MC-ASK waveform generation method, the third MC-ASK waveform generation method, the fourth MC-ASK waveform generation method, or other MC-ASK waveform generation methods.

[0215] In other embodiments, the signal generation method of the first signal may be an MC-FSK waveform generation method, such as the aforementioned first MC-FSK waveform generation method, the second MC-FSK waveform generation method, or other MC-FSK waveform generation methods.

[0216] In some embodiments, the first signal is generated in the same manner as the target signal.

[0217] For example, both the first signal and the target signal adopt the MC-ASK waveform generation method or the MC-FSK waveform generation method.

[0218] As an example, the first signal and the target signal both adopt the first MC-ASK waveform generation mode, the second MC-ASK waveform generation mode, the third MC-ASK waveform generation mode or the fourth MC-ASK waveform generation mode, or both adopt the first MC-FSK waveform generation mode or the second MC-FSK waveform generation mode, etc.

[0219] It should be understood that when the first signal and the target signal are generated in the same manner, the first signal and the target signal may use the same signal generation parameters, or they may use different signal generation parameters. For example, when the first signal and the target signal both use the second MC-ASK waveform generation manner, the third MC-ASK waveform generation manner, or the MC-FSK waveform generation manner, they use different numbers of segments M, or when both use the fourth MC-ASK waveform generation manner, they use different S, M, or N parameters, etc.

[0220] In some embodiments, the signal generation method of the first signal and the signal generation method of the target signal are independent, for example, they are different.

[0221] For example, the first signal adopts the MC-ASK waveform generation method, and the target signal adopts the MC-FSK waveform generation method.

[0222] As a specific example, the first signal adopts a first MC-ASK waveform generation method, the target signal adopts a second MC-FSK waveform generation method, and so on.

[0223] As another specific example, the first signal adopts a first MC-ASK waveform generation method, the target signal adopts a second MC-ASK waveform generation method, and so on.

[0224] In some embodiments, the signal generation method of the first signal is predefined, or preconfigured by the transmitting end device.

[0225] That is, the receiving device can know in advance the signal generation method of the first signal, so that the receiving device can receive the first signal in an appropriate receiving method, and further determine the signal generation method and / or resource location of the target signal based on the first signal.

[0226] In some embodiments, the first signal may include first indication information for indicating the resource location of the target signal and / or information related to the signal generation method of the target signal. That is, the first signal may explicitly indicate the resource location of the target signal and / or information related to the signal generation method of the target signal.

[0232] In other embodiments, the target signal may be generated by an MC-FSK waveform generation method, such as the aforementioned first MC-FSK waveform generation method or the second MC-FSK waveform generation method, or may be other MC-FSK waveform generation methods.

[0233] It should be understood that the above-mentioned signal generation method is only an example, and the target signal can also adopt other multi-carrier based waveform generation methods, which is not limited in this application.

[0234] In some embodiments, the signal generation parameter corresponding to the target signal includes at least one of the following:

[0235] The modulation method used to generate the target signal, such as ASK (such as OOK) or FSK;

[0236] The number of segments of N subcarriers used to carry the target signal, where N is a positive integer;

[0241] The subcarrier spacing corresponding to the target signal;

[0242] The position of the modulated subcarrier in a segment;

[0243] The cyclic prefix (CP) length of the OFDM symbol.

[0244] In some embodiments, for the OOK modulation mode, the number of segments of the N subcarriers used to carry the target signal is greater than or equal to 1.

[0245] In some embodiments, for the FSK modulation mode, the number of segments of the N subcarriers used to carry the target signal is M pairs or 2 M indivual.

[0246] In some embodiments, for an OOK modulation scheme, the bit carrying scheme in a segment may refer to:

[0247] Different segments carry different information, such as the second MC-ASK waveform generation method; or,

[0248] Different segments carry the same information, such as the third MC-ASK waveform generation method.

[0249] In some embodiments, for an FSK modulation mode, the bit carrying mode in a segment may refer to:

[0250] Each pair of segments carries 0 and 1 respectively, such as the first MC-FSK waveform generation method; or,

[0251] One segment carries 0, and the other segments carry 0, for example, the second MC-FSK waveform generation method.

[0252] In some embodiments, for the first MC-ASK waveform generation mode and the third MC-ASK waveform generation mode, the number of bits carried by an OFDM symbol is 1; for the second MC-ASK waveform generation mode and the fourth MC-ASK waveform generation mode, the number of bits carried by an OFDM symbol is M.

[0253] In some embodiments, for the fourth MC-FSK waveform generation mode, the signal generation parameters corresponding to the target signal may further include the number S of sampling points and the number N of subcarriers.

[0254] In some embodiments, the guard band information between segments may include: whether there is a guard band between segments, and / or guard band size information.

[0255] In some embodiments, the subcarrier spacing corresponding to the target signal may be the same as or different from the subcarrier spacing corresponding to other signals multiplexed within the frequency band.

[0256] In some embodiments, for the third MC-ASK waveform generation method, when each segment carries 1 bit, the position of the modulated subcarrier in a segment may refer to: the position of the modulated subcarrier in a segment in the segment.

[0257] In some embodiments, if there are multiple CP lengths, the transmitting device may indicate a target CP length corresponding to an OFDM symbol through a first signal.

[0258] In some embodiments, the subcarrier information corresponding to the target signal includes: position information and / or quantity information of the subcarriers used to carry the target signal. For example, when the resource location of the target signal and the resource location of the first signal are not associated (e.g., do not overlap or partially overlap), the positions of the N subcarriers corresponding to the target signal can be indicated by the first signal.

[0259] In some embodiments of the present application, the method 200 further includes:

[0260] The transmitting end device transmits the target signal using the signal generation method and / or resource location of the target signal indicated by the first signal.

[0261] Correspondingly, the receiving end device receives the target signal according to the signal generation method and / or resource location indicated in the first signal, thereby ensuring that the receiving end device correctly demodulates the target signal and ensures the reception performance of the target signal.

[0262] In summary, in the embodiments of the present application, the transmitting device can flexibly select the signal generation method of the target signal as needed, and further indicate the signal generation method and / or resource location information of the target signal to the receiving device through the first signal. In this way, the receiving device can receive the target signal according to the signal generation method and / or resource location information indicated by the first signal, thereby ensuring that the receiving device correctly demodulates the target signal and ensures the reception performance of the target signal.
