Wearable devices, also known as wearable smart devices, are a general term for wearable devices that are intelligently designed by applying wearable technology to everyday wear, such as glasses, gloves, watches, clothing, and shoes. Wearable devices are portable devices that are worn directly on the body or integrated into the user's clothing or accessories. Wearable devices are not merely hardware devices, but achieve powerful functionality through software support, data interaction, and interaction with the cloud. Wearable smart devices in a broad sense include devices that are fully functional, large in size, and can achieve all or part of their functionality without relying on a smartphone, such as smartwatches and smart glasses, and further include devices that are dedicated to only one type of application function and need to be used in conjunction with a smartphone, such as smart bracelets and smart jewelry that monitor various biometric information.

[0031] Exemplary, a communication system 100 to which an embodiment of the present application applies is shown in Figure 1. The communication system 100 includes a network device 110, which may be a device that communicates with terminal devices 120 (or communication terminals, referred to as terminals). The network device 110 provides communication coverage to a specific geographic area and can communicate with terminal devices located within that coverage area.

[0032] Figure 1 illustrates one network device and two terminal devices, but the communication system 100 may optionally include multiple network devices, and the coverage of each network device may include other numbers of terminal devices; the embodiments of this application are not limited thereto.

[0033] The communication system 100 may optionally further include other network entities such as a network controller or a mobility management entity, and the embodiments of this application are not limited thereto.

[0034] In the embodiments of this application, it is understood that devices having communication functions within a network / system may be referred to as "communication devices." Taking the communication system 100 shown in Figure 1 as an example, the communication devices may include network devices 110 and terminal devices 120 that have communication functions. The network devices 110 and terminal devices 120 are specific devices described above, and a detailed description is omitted here. In addition, the communication devices may also include other devices within the communication system 100, such as other network entities such as network controllers and mobility management entities, but the embodiments of this application are not limited thereto.

[0035] It is understood that the terms "system" and "network" as used herein are generally interchangeable. The terms "and / or" as used herein describe only the relationship between related objects and indicate that three types of relationships may exist. For example, A and / or B means that A exists alone, A and B exist simultaneously, or B exists alone. The character " / " in the text generally indicates that the preceding and following related objects are in an "or" relationship.

[0036] It is understood that the “instruction” referred to in the embodiments of this application may be direct instruction, indirect instruction, or an indication of a relationship. For example, when A indicates B, it may mean that A directly indicates B, for example, that B is obtainable through A; when A indirectly indicates B, for example, that A indicates C and B is obtainable through C; or it may indicate a relationship between A and B.

[0037] In the description of the embodiments of this application, the term "corresponding" may indicate a direct or indirect correspondence between the two, a related relationship between the two, or a relationship such as "instructing and being instructed" or "setting and being set."

[0038] In the embodiments of this application, “pre-definition” can be implemented by pre-storing codes, tables, or other relevant information corresponding to devices (including, for example, terminal devices and network devices), but this application does not limit the specific implementation method. For example, pre-definition may be defined in a protocol.

[0039] In the embodiments of this application, the “protocol” may refer to a standard protocol in the field of communications, and may include, for example, the LTE protocol, the NR protocol, and related protocols applicable to future communications systems, but this application is not limited thereto.

[0040] To facilitate understanding of the technical solutions provided in the embodiments of this application, the related technologies of this application will be described below.

[0041] 1. Zero-power communication Key technologies for zero-power communications include energy harvesting, backscatter communications, and low-power technologies.

[0042] As shown in Figure 2, a typical zero-power communication system (e.g., an RFID system) includes network equipment (e.g., an RFID system reader / writer) and zero-power terminals (e.g., electronic tags). The network equipment is used to transmit radio power supply signals and downlink communication signals to the zero-power terminals and to receive backscatter signals from the zero-power terminals. A basic zero-power terminal includes an energy harvesting module, a backscatter communication module, and a low-power computing module. In addition, the zero-power terminal may further include memory or sensors, which are used to store basic information such as item identification information, or sensing data such as ambient temperature and ambient humidity.

[0043] For example, an energy harvesting module collects the energy of radio waves in space (as shown in Figure 2, radio waves emitted by network equipment) and is used to drive the low-power computing module of a zero-power terminal and to realize backscatter communication. After acquiring energy, the zero-power terminal can receive control commands from network equipment and transmit data to the network equipment using a backscatter method based on control signaling. The transmitted data may be data stored by the zero-power terminal itself (e.g., identity identifiers or pre-written information, product production date, brand, manufacturer, etc.). The zero-power terminal can also be equipped with various sensors, which will allow it to report data collected by these sensors based on the zero-power mechanism.

[0044] The following describes the key technologies in zero-power communication.

[0045] 1. RF Energy Harvesting (RF Power Harvesting) As shown in Figure 3, the RF energy harvesting module collects spatial electromagnetic wave energy based on the principle of electromagnetic induction, thereby obtaining the energy necessary for the operation of the zero-power terminal, such as energy to drive low-power demodulation and modulation modules, sensors, memory readouts, etc. Therefore, conventional batteries are not required for the zero-power terminal.

[0046] 2. Backscattering As shown in Figure 4, the zero-power terminal receives a carrier signal transmitted by network equipment, modulates the carrier signal to load 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 functions are closely inseparable. Load modulation completes the modulation process by adjusting and controlling the circuit parameters of the zero-power terminal's oscillation circuit according to the tempo of the data stream, thereby changing parameters such as the magnitude of the zero-power terminal's impedance. Load modulation techniques mainly include two types: resistive load modulation and capacitive load modulation. As shown in Figure 5, in resistive load modulation, a resistor is connected in parallel to the load, and this resistor is turned on / off based on the control of the binary data stream. As the circuit voltage changes by turning the resistor on / off, amplitude shift modulation (ASK) is realized. That is, the modulation and transmission of the signal are realized by adjusting the amplitude of the backscatter signal of the zero-power terminal. Similarly, in capacitive load modulation, the resonant frequency of the circuit is changed by turning a capacitor on / off, thereby realizing frequency shift modulation (FSK). In other words, signal modulation and transmission are achieved by adjusting the operating frequency of the backscatter signal of the zero-power terminal.

[0047] As can be seen from the above, zero-power terminals apply information modulation to the incident signal using a load modulation method, thereby realizing a backscatter communication process. Therefore, zero-power terminals have the following significant advantages. (1) Because it does not actively emit signals, complex RF circuits such as PAs and RF filters are unnecessary. (2) Since it does not actively generate high-frequency signals, a high-frequency crystal oscillator is not required. (3) Backscatter communication eliminates the need for the terminal to consume its own energy for signal transmission.

[0048] 3, encoding technology Data transmitted by zero-power terminals can represent binary "1s" and "0s" using different coding formats. Radio frequency identification (RFID) systems use one of the following coding schemes: general, non-zero return (NRZ) coding, Manchester coding, unipolar return zero coding, differential two-phase phase (DBP) coding, differential coding, pulse interval coding (PIE), two-phase space (FM0) coding, Miller coding, and differential coding. In simple terms, different coding techniques are techniques that use different pulse signals to represent "0s" and "1s".

[0049] Zero-power communication offers significant advantages such as extremely low cost, zero power consumption, and small size, making it widely applicable across various industries. For example, it can be applied to vertical sectors such as logistics, smart warehouses, smart agriculture, energy and power, and industrial internet, as well as to consumer applications such as smart wearables and smart homes.

[0050] In some scenarios, zero-power terminals can be classified into the following types based on their energy source and usage:

[0051] 1. Passive Zero Power Terminal Zero-power terminals (e.g., electronic tags in RFID systems) do not need to have a built-in battery and, when in close proximity to network equipment (RFID system readers / writers), are within the range of the near-field formed by the antenna radiation of the network equipment. Therefore, the antenna of the zero-power terminal generates an induced current through electromagnetic induction, and this induced current drives the low-power chip circuitry of the zero-power device. This enables operations such as demodulation of forward link signals and modulation of signals in the reverse link (also called a reflected link). In the case of backscatter links, the zero-power terminal transmits signals using a backscatter implementation.

[0052] Passive zero-power terminals do not require an internal battery to drive either the forward or reverse link, demonstrating that they are truly zero-power terminals.

[0053] Passive zero-power terminals do not require batteries, and their radio frequency and baseband circuits are very simple, eliminating the need for devices such as low-noise amplifiers (LNAs), power amplifiers (PAs), crystal oscillators, and analog-to-digital converters (ADCs). As a result, they have many advantages, including being small, lightweight, very inexpensive, and having a long service life.

[0054] 2. Semi-passive zero-power terminals A semi-passive zero-power terminal itself does not have a conventional battery, but it can collect radio wave energy using an RF energy collection module. The collected energy is then stored in an energy storage unit (e.g., a capacitor). After the energy storage unit acquires the energy, it can drive the low-power consumption chip circuitry of the zero-power terminal. This enables functions such as demodulation of forward link signals and modulation of reverse link signals. In the case of backscatter links, the zero-power terminal transmits signals using a backscatter implementation.

[0055] The semi-passive zero-power terminal does not require an internal battery to drive either the forward or reverse link. While it uses capacitive stored energy during operation, this energy originates from radio energy collected by an energy collection module, making it a truly zero-power device.

[0056] Semi-passive zero-power terminals inherit many of the advantages of passive zero-power terminals, resulting in numerous benefits such as smaller size, lighter weight, very low cost, and a longer service life.

[0057] 3. Active Zero Power Terminals Zero-power terminals used in some scenarios may be active zero-power terminals, and such devices may have a built-in battery. The battery is for driving the low-power chip circuitry of the zero-power terminal. This enables functions such as demodulation of forward link signals and modulation of reverse link signals. However, in the case of backscatter links, zero-power terminals transmit signals using a backscatter implementation. Therefore, the zero-power nature of such devices is mainly reflected in the fact that reverse link signal transmission does not require power from the terminal itself and uses a backscatter method.

[0058] Active zero-power terminals use a built-in battery to power the RFID chip, extending the read / write range and improving communication reliability. Therefore, they are applied in scenarios where there are relatively high requirements for communication range and read latency.

[0059] In some scenarios, zero-power devices can be classified into the following types based on the type of transmitter:

[0060] 1) Zero-power devices based on backscattering This type of zero-power device transmits uplink data using the backscattering method described above. Such a zero-power device does not have an active transmitter that transmits data actively, but only a backscattering transmitter. Therefore, when this type of zero-power device transmits data, it is necessary to have a carrier wave provided by network equipment, and the zero-power device achieves data transmission by performing backscattering based on the carrier wave.

[0061] 2) Zero-power devices based on active transmitters Such zero-power devices perform uplink data transmission using an active transmitter that has the capability to transmit actively. Therefore, when transmitting data, such zero-power devices can transmit data simply by using their own active transmitter, and do not need to provide a carrier wave from network equipment. Examples of active transmitters applicable to zero-power devices include ultra-low power ASK transmitters and ultra-low power FSK transmitters, which can reduce total power consumption to 400-600 μW when transmitting a 100 μW signal.

[0062] 3) Zero-power device equipped with both a backscatter transmitter and an active transmitter. Such zero-power devices can accommodate both backscatter and active transmitters. These zero-power devices can determine which signal transmission method (i.e., whether to use an active transmitter or a backscatter transmitter) to use based on different circumstances (e.g., power supply conditions, available environmental energy) or network equipment scheduling.

[0063] As the Internet of Things (IoT) develops rapidly, existing IoT communication technologies are no longer able to meet the IoT communication needs in many scenarios. For example,

[0064] 1. Harsh communication environment Some IoT scenarios may face extreme environments such as high temperatures, extremely low temperatures, high humidity, high pressure, high radiation, and high-speed movement. Examples include ultra-high voltage substations, rail monitoring for high-speed trains, environmental monitoring in cold regions, and industrial production lines. In these scenarios, existing IoT devices may not function properly due to the limitations of normal power supply operating environments. Furthermore, extreme operating environments are disadvantageous for IoT maintenance (e.g., battery replacement).

[0065] 2. Need for extremely small device form factors In some IoT communication scenarios, such as food traceability, product distribution, and smart wearables, terminals are required to be extremely small, which is convenient for use in these scenarios. For example, IoT terminals used for product management as part of distribution typically take the form of electronic tags and are embedded in product packaging in a very small size. Also, lightweight wearable devices, for example, can meet user needs while simultaneously improving the user experience.

[0066] 3. Ultra-low-cost IoT communication needs In many IoT communication scenarios, the cost of IoT devices must be sufficiently low to enhance their competitiveness against alternative technologies. For example, in logistics or warehouse management scenarios, IoT devices can be attached to each item to facilitate the management of large volumes of goods in circulation. This enables precise management of the entire logistics process and cycle through communication between the device and the logistics network. In these scenarios, the price of IoT devices must be sufficiently competitive.

[0067] Therefore, to cover these unmet IoT communication needs, it is necessary to develop ultra-low-cost, extremely small, battery-free / maintenance-free IoT devices, even on cellular networks, and zero-power IoT can precisely meet this need.

[0068] Zero-power IoT (Internet of Things) is also called 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 refer to IoT devices that utilize various types of environmental energy, such as radio frequency (RF) energy, light energy, solar energy, thermal energy, and mechanical energy. Such devices do not need to have energy storage capabilities, and may have very limited energy storage capabilities, such as using a capacitor with a capacitance of several tens of microfibers.

[0069] Ambient IoT can be applied to at least the following four types of scenarios. 1. Object identification, e.g., logistics, production line product management, supply chain management, 2. Environmental monitoring, for example, monitoring of temperature, humidity, and harmful gases in the work environment and natural environment. 3. Location determination, for example, indoor location determination, smart item search, location determination of items on a production line, etc. 4. Smart control, for example, smart control of various electrical appliances in a smart home (turning air conditioners on / off, temperature adjustment), and smart control of various equipment in an agricultural greenhouse (automatic irrigation, fertilization).

[0070] To further reduce power consumption in terminal equipment, it is conceivable to introduce a Wake Up Receiver (WUR) to receive the wake-up signal. The WUR features ultra-low cost, ultra-low complexity, and ultra-low power consumption, and primarily receives the wake-up signal (WUS) using an envelope detection method. Therefore, the WUS received by the WUR differs from the signal carried by the Physical Downlink Control Channel (PDCCH) in terms of modulation method, waveform, etc. The wake-up signal is primarily an envelope signal obtained by applying amplitude shift keying (ASK) to the carrier signal. Demodulation of the envelope signal is also primarily performed by driving a low-power circuit using energy provided by the wireless RF signal, thus allowing for a power-free operation. The WUR can also receive power from the terminal equipment, and regardless of the power supply method, the WUR's power consumption is significantly reduced compared to conventional UE receivers. The WUR can function as an add-on module to the UE receiver when integrated with the UE, or it can function as a standalone wake-up function module for the UE.

[0071] A block diagram of the receiver system based on the wake-up signal is shown in Figure 6. The wake-up receiver (WUR) receives the wake-up signal and can instruct the UE (User Equipment) to activate the main receiver if necessary. Otherwise, the UE's main receiver can remain off.

[0072] In some scenarios, a wake-up radio (WUR) signal is used to enable energy saving in a device. The WUR AP notifies the WURnon-AP STA of energy-saving operation via a WUR wake-up frame. The wake-up frame is carried into a WUR Physical Layer Protocol Data Unit (PPDU) frame. As shown in Figure 7, one WUR PPDU frame contains three parts: a legacy preamble, a WUR-Sync, and a WUR-Data. Here, the legacy preamble's role is to protect the WUR-Sync and WUR-Data portions; it is a non-WUR portion reserved for compatibility and uses conventional orthogonal frequency-division multiplexing (OFDM) modulation and a 20 MHz bandwidth. The WUR-Sync is used to assist in the identification and demodulation of the WUR-Data portion, which is used to carry the WUR PSDU.

[0073] The WUR-Sync and WUR-Data sections use an On-Off Keying (OOK) modulation scheme and 4 MHz of the 20 MHz channel bandwidth. The OOK modulation principle involves modulating the amplitude of the carrier signal into non-zero and zero values, corresponding to On and Off, respectively, to represent information bits. OOK is also called binary amplitude shift modulation (2ASK). Figure 8 shows the principle of OOK modulation; the WUR-Data section carries user information, which is encoded, then OOK modulation is applied to form MC-OOK symbols of the corresponding length.

[0074] The above OOK signal is generated by multi-carrier (MC) modulation, and is therefore called an MC-OOK signal. The MC-OOK signal may also be an OOK signal generated by employing a multi-carrier modulation scheme such as OFDM modulation, maintaining good compatibility with OFDM systems and reducing the complexity of the transmitter that arises with the implementation of WUR signals. Figure 9 shows an MC-OOK signal generated by multi-carrier modulation. When the amplitude values ​​corresponding to multiple subcarriers in the frequency domain are mapped and converted into a time-domain signal via an inverse discrete Fourier transform (IDFT), the waveform approximates the waveform formed by ASK modulation. Here, bit 1 is represented by the high level of the signal, and bit 0 is represented by the low level of the signal.

[0075] In some scenarios, the following MC-ASK waveform generation method can be considered, where K represents the point size of the IDFT and N represents the number of subcarriers used for transmitting the WUS signal.

[0076] First MC-ASK waveform generation method (denoted as OOK-1): Each OFDM symbol carries 1 bit. Here, the OOK signal output after the subcarrier carrying the WUS signal is modulated and then passes through IDFT is 1, and the OOK signal output corresponding to the case where the subcarrier carrying the WUS signal is zero power is 0. Figure 10 shows the WUS signal generation process based on the OOK-1 waveform generation method.

[0077] 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 segment carrying 1 bit of information. In each segment, if all subcarriers are modulated, the corresponding output OOK signal is 1; if all subcarriers are at zero power, the corresponding output OOK signal is 0. Figure 11 shows the AMP signal generation process based on the OOK-2 waveform generation method when M=2.

[0078] Third MC-ASK waveform generation method (denoted as OOK-3): Each OFDM symbol carries 1 bit. The N subcarriers carrying the AMP signal are divided into M segments. In each of the M segments, if one subcarrier is modulated and the other subcarriers are at zero power, the corresponding output OOK signal is 1. If all subcarriers in all segments are at zero power, the corresponding output OOK signal is 0.

[0079] The fourth MC-ASK waveform generation method (denoted as OOK-4): Each OFDM symbol carries M bits in the time domain. N subcarriers carrying the AMP signal are generated by DFT, and M bits are represented by S sampling points. The S sampling points undergo DFT transformation to form S subcarriers. Furthermore, the S subcarriers undergo truncation and other processes to form N subcarriers, and then the OOK signal is generated through IDFT transformation. Figure 12 shows the AMP signal generation process based on the OOK-3 waveform generation method when M=4.

[0080] In addition to MC-ASK waveforms, LP-WUS may also use MC-FSK waveforms. For example, the following MC-FSK waveform generation method may be used.

[0081] First MC-FSK waveform generation method (denoted as FSK-1): The N subcarriers carrying the AMP signal are divided into M pairs of segments. In each OFDM symbol, one segment from each pair is modulated, and the other segment is at zero power.

[0082] The 2 MC-FSK waveform generation method (denoted as FSK-2): The N subcarriers that carry the AMP signal are 2 M It is divided into segments. In each OFDM symbol, 2 M One of the segments is modulated, while the other segments are at zero power.

[0083] The different MC-ASK and MC-FSK signal generation methods described above differ in bitrate, resource overhead, and performance. In practical applications, transmitting equipment can flexibly select one of several signal generation methods based on specific needs. In this case, how the receiving equipment receives the signal becomes an urgent issue that needs to be addressed.

The first signal is positioned in the first part, and the target signal includes at least the data part but does not include the first part.

[0118] Selectively, the first portion may be a portion dedicated to carrying the first signal in the second signal.

[0119] In some embodiments, the first signal may be used to explicitly indicate the signal generation method and / or resource location information of the target signal, or to implicitly indicate the signal generation method and / or resource location information of the target signal. For example, the signal generation methods of the first signal and the target signal may be the same, or the resource locations of the first signal and the target signal may be related. This application does not limit the specific indication methods.

[0120] In some embodiments, the first signal is used to indicate the signal generation method for the target signal. The first signal is used to indicate a specific signal generation method for the target signal and / or signal generation parameters corresponding to the target signal.

[0121] In some embodiments, the first signal is used to indicate the resource location information of the target signal. The first signal is used to indicate information about the subcarriers occupied by the target signal, such as the number and / or location of the subcarriers.

[0122] The relationship between the resource location of the first signal and the resource location of the target signal will be explained below by combining Examples 1 and 2.

[0123] Example 1: The resource location of the first signal and the resource location of the target signal are related. Selectively, the relationship may be predefined, pre-configured by the transmitting device, or indicated by the transmitting device in the first signal.

[0124] Case 1: The receiving device can know the resource location of the first signal in advance. For example, the resource location of the first signal is either predefined or pre-set by the transmitting equipment.

[0125] Selectively, the resource location of the first signal may include the number and / or location of subcarriers occupied by the first signal.

[0126] For example, if the receiving device can know in advance the number and / or location of the subcarriers occupied by the first signal, the receiving device can receive the first signal at the corresponding resource location.

[0127] In some embodiments, the receiving device may determine the resource location of the target signal by combining the resource location of the first signal, which has been determined in advance, with the relationship between the resource location of the first signal and the resource location of the target signal.

[0128] Case 2: The receiving device can determine the resource location of the target signal in advance. For example, the resource location of the target signal is either predefined or pre-set by the transmitting equipment.

[0129] Selectively, the resource location of the target signal may include the number and / or location of subcarriers occupied by the target signal.

[0130] In some embodiments, the receiving device may determine the resource location of the first signal by combining the resource location of the target signal, which it has known in advance, with the relationship between the resource location of the first signal and the resource location of the target signal, and then receive the first signal at the corresponding resource location.

[0131] In some embodiments, the resource location of the first signal and the resource location of the target signal are related. The time-domain resources of the first signal and the time-domain resources of the target signal are related, and / or This may also include the condition that the frequency domain resources of the first signal and the frequency domain resources of the target signal are related.

[0132] In some embodiments, the time-domain resources of the first signal and the time-domain resources of the target signal are related. This may include the condition that the time-domain resources of the first signal and the time-domain resources of the target signal are adjacent or have a certain time interval between them.

[0133] Selectively, the time interval may be predefined or set by the transmitting device.

[0134] In some embodiments, the frequency domain resources of the first signal and the frequency domain resources of the target signal are related. This may include the condition that the frequency domain resources occupied by the target signal are the same as those occupied by the first signal, or that the frequency domain resources occupied by the first signal are a part of the frequency domain resources occupied by the target signal.

[0135] In some embodiments, the frequency domain resources of the first signal may include subcarriers occupied by the first signal, i.e., subcarriers for carrying the first signal, and the frequency domain resources of the target signal may include subcarriers occupied by the target signal, i.e., subcarriers for carrying the target signal.

[0136] The following describes the relationship between the frequency domain resources of the first signal and the frequency domain resources of the target signal by combining Examples 1-1 to 1-3.

[0137] Example 1-1: The subcarrier for carrying the first signal and the subcarrier for carrying the target signal are the same.

[0138] In other words, regardless of the signal generation method employed by the target signal, the subcarrier occupied by the first signal and the subcarrier occupied by the target signal are the same.

[0139] In some specific embodiments, as shown in Figure 14, the target signal is generated based on a first MC-ASK waveform generation scheme and carried via N subcarriers (i.e., SC#0 to SC#N-1). The subcarriers occupied by the first signal and the subcarriers occupied by the target signal are the same.

[0140] In some other specific embodiments, as shown in Figure 15, the target signal is generated based on a second MC-ASK waveform generation scheme and carried via N subcarriers (i.e., SC#0 to SC#N-1). These N subcarriers are divided into two segments (i.e., M=2), and the subcarriers occupied by the first signal and the subcarriers occupied by the target signal are identical.

[0141] Example 1-2: The subcarrier for carrying the first signal is the same as the subcarrier corresponding to one or more of the N segments. The N segments are all the segments corresponding to the N subcarriers for carrying the target signal, where N is a positive integer.

[0142] In this embodiment 1-2, the N subcarriers for carrying the target signal are divided into M segments, and the first signal occupies the subcarriers corresponding to X segments out of the M segments. Here, X is a positive integer, and X <Mである。

[0143] Selectively, the X segments may be the first X segments, the last X segments, or an intermediate X segments out of M segments.

[0144] Selectively, the positions of the X segments within the M segments may be predefined or set by the transmitting device.

[0145] Selectively, the relationship between the resource location of the first signal and the resource location of the target signal is: This may include location information for X segments within M segments.

[0146] In some specific embodiments, as shown in Figure 16, the target signal is generated based on a second MC-ASK waveform generation scheme and carried via N subcarriers (i.e., SC#0 to SC#N-1). These N subcarriers are divided into two segments (i.e., M=2), and the first signal may occupy the subcarrier corresponding to the first segment of the two segments (i.e., the segment corresponding to m=0), or the subcarrier corresponding to the second segment of the two segments (i.e., the segment corresponding to m=1), or the first signal may be transmitted to both subcarriers corresponding to the two segments.

[0147] In some other specific embodiments, as shown in Figure 17, the target signal is generated based on a second MC-ASK waveform generation scheme and carried via N subcarriers (i.e., SC#0 to SC#N-1). These N subcarriers are divided into four segments (i.e., M=4), and the first signal may occupy the subcarriers corresponding to the first two segments of the four segments (i.e., the segments corresponding to m=0 and m=1), the last two segments of the four segments (i.e., the segments corresponding to m=2 and m=3), or the two middle segments of the four segments (i.e., the segments corresponding to m=1 and m=2).

[0148] Example 1-3: The subcarrier for carrying the first signal and Y subcarriers out of N subcarriers for carrying the target signal are identical. Here, N is a positive integer, Y is a positive integer, and Y <Nである。

[0149] In other words, in this embodiment 1-3, the subcarrier corresponding to the first signal is a portion of the N subcarriers corresponding to the target signal. This portion of subcarriers may be independent of the number of segments of the N subcarriers corresponding to the target signal.

[0150] Selectively, the positions of Y subcarriers in N subcarriers may be predefined or set by the transmitting equipment.

[0151] In some embodiments, the Y subcarriers may be the central Y subcarriers among the N subcarriers, the first Y subcarriers among the N subcarriers, or the last Y subcarriers.

[0152] Selectively, the relationship between the resource location of the first signal and the resource location of the target signal is: This may include positional information for Y subcarriers within N subcarriers.

[0153] In some specific embodiments, as shown in Figure 18, the target signal is generated based on a first MC-ASK waveform generation scheme and carried via N subcarriers (i.e., SC#0 to SC#N-1). The first signal occupies some of these N subcarriers.

[0154] In some other specific embodiments, as shown in Figure 19, the target signal is generated based on a second MC-ASK waveform generation scheme and carried via N subcarriers (i.e., SC#0 to SC#N-1). These N subcarriers are divided into two segments (i.e., M=2), and the first signal occupies some of these N subcarriers.

[0155] Example 2: The resource location of the first signal and the resource location of the target signal are not related; that is, the resource location of the first signal and the resource location of the target signal are independent.

[0156] In this embodiment 2, if the receiving device can know the resource location of the first signal in advance, it can receive the first signal at the corresponding resource location.

[0157] For example, the resource location of the first signal is either predefined or pre-set by the transmitting equipment.

[0158] In some embodiments, the receiving device may receive the first signal based on the resource location of the first signal which is known in advance, and the first signal may include information indicating the resource location of the target signal. In this case, the receiving device can obtain the resource location of the target signal based on the indication in the first signal.

[0159] In some embodiments, the resource location of the first signal and the resource location of the target signal are not related. The subcarrier for carrying the first signal and the subcarrier for carrying the target signal may not overlap, or may partially overlap.

[0160] In some specific embodiments, as shown in Figure 20, the target signal is generated based on a first MC-ASK waveform generation scheme and carried via N subcarriers (i.e., SC#0 to SC#N-1). The subcarriers occupied by the first signal and the subcarriers occupied by the target signal do not overlap.

[0161] In some other specific embodiments, as shown in Figure 21, the target signal is generated based on a first MC-ASK waveform generation scheme and carried via N subcarriers (i.e., SC#0 to SC#N-1). The subcarriers occupied by the first signal and the subcarriers occupied by the target signal partially overlap.

[0162] In some embodiments of this application, as shown in Figures 14-21, the target signal and other signals are multiplexed within a frequency band. Here, "other signals" refers to existing signals or channels in a communication system (i.e., legacy signals or channels), such as legacy signals or channels in an NR system, or existing signals or frames in a WIFI system.

[0163] In some embodiments, the signal generation method for the first signal may be an MC-ASK waveform generation method, such as the 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 any other MC-ASK waveform generation method.

[0164] In some other embodiments, the signal generation method for the first signal may be an MC-FSK waveform generation method, for example, the first MC-FSK waveform generation method, the second MC-FSK waveform generation method described above, or any other MC-FSK waveform generation method.

[0165] In some embodiments, the signal generation method for the first signal and the signal generation method for the target signal are the same.

[0166] For example, both the first signal and the target signal employ either the MC-ASK waveform generation method or the MC-FSK waveform generation method.

[0167] Specific examples include both the first signal and the target signal employing the first MC-ASK waveform generation method, the second MC-ASK waveform generation method, the third MC-ASK waveform generation method, or the fourth MC-ASK waveform generation method, or both employing the first MC-FSK waveform generation method or the second MC-FSK waveform generation method.

[0168] It is understood that if the signal generation method for the first signal and the target signal is the same, the first signal and the target signal may employ the same signal generation parameters, or they may employ different signal generation parameters. For example, if both the first signal and the target signal employ the second MC-ASK waveform generation method, the third MC-ASK waveform generation method, or the MC-FSK waveform generation method, they may employ different number of segments M, or if both employ the fourth MC-ASK waveform generation method, they may employ different S, M, or N parameters.

[0169] In some embodiments, the signal generation method for the first signal and the signal generation method for the target signal are independent and, for example, different.

[0170] For example, the first signal uses the MC-ASK waveform generation method, while the target signal uses the MC-FSK waveform generation method.

[0171] As a specific example, the first signal uses the first MC-ASK waveform generation method, and the target signal uses the second MC-FSK waveform generation method.

[0172] As another example, the first signal uses the first MC-ASK waveform generation method, and the target signal uses the second MC-ASK waveform generation method.

[0173] In some embodiments, the signal generation method for the first signal is predefined or pre-configured by the transmitting device.

[0174] In other words, the receiving device can know the signal generation method of the first signal in advance, thereby adopting an appropriate receiving method to receive the first signal, and further determining the signal generation method and / or resource location of the target signal based on the first signal.

[0175] In some embodiments, the first signal may include first instruction information used to indicate the resource location of the target signal and / or the signal generation method of the target signal. That is, the first signal can explicitly indicate the resource location of the target signal and / or the signal generation method of the target signal.

[0176] In some embodiments, the first instruction information described above is The signal generation method for the target signal, Signal generation parameters corresponding to the target signal, It is used to indicate at least one of the subcarrier information corresponding to the aforementioned target signal.

[0177] In some embodiments, the signal generation method for the target signal may be an MC-ASK waveform generation method, such as the 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 any other MC-ASK waveform generation method.

[0178] In some other embodiments, the signal generation method for the target signal may be an MC-FSK waveform generation method, for example, the first MC-FSK waveform generation method, the second MC-FSK waveform generation method, or any other MC-FSK waveform generation method.

[0179] The above signal generation method is merely an example, and the target signal may employ other multi-carrier based waveform generation methods, but this application is not limited thereto.

[0180] In some embodiments, the signal generation parameters corresponding to the target signal are: The modulation scheme used to generate the aforementioned target signal, for example, ASK (e.g., OOK) or FSK, The number of segments of N subcarriers for carrying the target signal, where N is a positive integer, and The number of subcarriers included in one segment, Bit transport method in segments, The number of bits carried by one orthogonal frequency division multiplexed OFDM symbol, Guard band information between segments, The subcarrier interval corresponding to the target signal, The position of the subcarrier modulated in one segment, It includes at least one of the following: the cyclic prefix CP length of the OFDM symbol.

[0181] In some embodiments, for the OOK modulation scheme, the number of N subcarrier segments for carrying the target signal is 1 or more.

[0182] In some embodiments, for an FSK modulation scheme, the number of subcarrier segments for carrying the target signal is M pairs or 2. M It is an individual.

[0183] In some embodiments, the bit transport scheme in a segment is as follows, relative to the OOK modulation scheme: Different segments carrying different information, for example, the second MC-ASK waveform generation method, This refers to different segments carrying the same information, such as the third MC-ASK waveform generation method.

[0184] In some embodiments, the bit transport scheme in a segment is different from the FSK modulation scheme. Each pair of segments carries 0 and 1 respectively, for example, the first MC-FSK waveform generation method, One segment 1 This means that one segment carries zeros, while other segments carry zeros, for example, the second MC-FSK waveform generation method.

[0185] In some embodiments, for the first MC-ASK waveform generation method and the third MC-ASK waveform generation method, the number of bits carried by one OFDM symbol is 1, and for the second MC-ASK waveform generation method and the fourth MC-ASK waveform generation method, the number of bits carried by one OFDM symbol is M.

[0186] In some embodiments, the fourth MC- A For the SK waveform generation method, the signal generation parameters corresponding to the target signal may further include the number of sampling points S and the number of subcarriers N.

[0187] In some embodiments, the guard band information between segments may include whether or not there is a guard band between segments, and / or information on the size of the guard band.

[0188] 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.

[0189] In some embodiments, for the third MC-ASK waveform generation scheme, if each segment carries 1 bit, the position of the modulated subcarrier in one segment refers to the position of the modulated subcarrier within that segment.

[0190] In some embodiments, when multiple CP lengths exist, the transmitting device can indicate a target CP length corresponding to one OFDM symbol via a first signal.

[0191] In some embodiments, the subcarrier information corresponding to the target signal includes positional and / or quantity information of subcarriers for carrying the target signal. For example, if the resource positions of the target signal and the resource positions of the first signal are not related (e.g., they do not overlap or partially overlap), the positions of N subcarriers corresponding to the target signal can be indicated via the first signal.

[0192] In some embodiments of this application, the method 200 is The transmitting device further includes transmitting a target signal by employing a signal generation scheme and / or resource location for the target signal indicated by the first signal.

[0193] Accordingly, the receiving device receives the target signal based on the signal generation method and / or resource location indicated in the first signal, thereby ensuring that the receiving device can correctly demodulate the target signal and guaranteeing the reception performance of the target signal.

[0194] In summary, in the embodiments of this application, the transmitting device can flexibly select a signal generation method for the target signal based on its needs, and further instructs the receiving device on the signal generation method and / or resource location information for the target signal via a first signal. As a result, the receiving device can receive the target signal based on the signal generation method and / or resource location information instructed by the first signal, thereby ensuring that the receiving device correctly demodulates the target signal and guaranteeing the reception performance of the target signal.
