[0097] The electronic devices involved in the embodiments of the present application may be active devices. Active devices refer to devices that have their own power supply and can actively generate and transmit signals, such as mobile phones, computers, smart watches, smart bracelets, etc.

[0098] It can also be a passive device. A passive device refers to a device that does not require a power supply or can work by receiving energy from other devices. It can be called a zero-power device, a zero-power terminal, a low-power device, a low-power terminal, etc.

[0099] It can also be a device that obtains energy from the environment, which can be called an ambient energy IoT device;

[0100] It can also be a device deployed at a fixed location, which can be called a zero-power site, a low-power site, etc.

[0101] FIG1 shows a schematic diagram of a zero-power communication system 100 provided by the related art. The zero-power communication system 100 includes a network device 120 and a zero-power device 140 .

[0102] The network device 120 is used to send wireless power supply signals, downlink communication signals and receive backscatter signals from the zero-power device 140 to the zero-power device 140. The zero-power device 140 is also called an ambient power enabled Internet of Things (Ambient IoT) device, which includes an energy collection module 141, a backscatter communication module 142 and a low-power computing module 143. The energy collection module 141 can collect energy carried by radio waves (wireless signals) in space, and is used to drive the low-power computing module 143 of the zero-power device 140 and realize backscatter communication. After obtaining energy, the zero-power device 140 can receive control signaling from the network device 120 and send data to the network device 120 based on the backscattering method according to the control signaling. The sent data can come from data stored in the zero-power device 140 itself (such as an identity or pre-written information, such as the production date, brand, manufacturer, etc. of the product).

[0103] Zero-power device 140 may also include a sensor module 144 and a memory 145. Sensor module 144 may include various sensors, and zero-power device 140 may report data collected by these sensors based on a zero-power mechanism. Memory 145 is used to store basic information (such as item identification) or obtain sensor data such as ambient temperature and humidity.

[0104] The zero-power device 140 itself does not require a battery, and at the same time, the low-power computing module 143 can perform simple signal demodulation, decoding or encoding, modulation and other simple calculation tasks. Therefore, the zero-power module only requires a very simple hardware design, making the zero-power device 140 very low in cost and small in size.

[0105] The network device 120 includes but is not limited to: cellular network devices, such as 5G / 6G network devices, base station devices; WiFi / WLAN network devices, such as access points (APs), routers, mobile access points, etc., and the mobile access point is, for example, a mobile phone.

[0106] The zero-power device 140 includes but is not limited to: handheld devices, wearable devices, vehicle-mounted devices and Internet of Things devices, etc. The zero-power device 140 can be at least one of a mobile phone, a tablet computer, an e-book reader, a laptop computer, a desktop computer, a television, a game console, an augmented reality (AR) terminal, a virtual reality (VR) terminal and a mixed reality (MR) terminal, a wearable device, a handle, an electronic tag and a controller, etc.

[0107] Next, the key technologies of zero-power communication are introduced:

[0108] Radio Frequency Power Harvesting

[0109] Figure 2 shows a schematic diagram of RF energy harvesting provided by related technologies. RF energy harvesting is based on the principle of electromagnetic induction, using a radio frequency (RF) module to conduct electromagnetic induction and maintain a parallel relationship with a capacitor C and a load resistor R. L By connecting to the power supply, the energy required to operate zero-power devices can be collected from electromagnetic waves in space, such as for driving low-power demodulation modules, modulation modules, sensors, and memory reading. Therefore, zero-power devices do not require traditional batteries.

[0110] Back scattering communication

[0111] Figure 3 shows a schematic diagram of the backscatter communication process provided by related art. A zero-power device 140 receives a wireless signal carrier 131 transmitted by a transmitter (TX) module 121 of a network device 120 using an amplifier (AMP) 122. It modulates the wireless signal carrier 131, loads the information to be transmitted using a logic processing module 147, and harvests radio frequency energy using an energy harvesting module 141. Zero-power device 140 radiates the modulated reflected signal 132 using an antenna 146. This information transmission process is called backscatter communication. A receiver (RX) module 123 of the network device 120 receives the modulated reflected signal 132 using a low-noise amplifier (LNA) 124. Backscatter and load modulation are closely related. Load modulation achieves this by adjusting and controlling the circuit parameters of the oscillator circuit of the zero-power device 140 according to the data stream's rhythm, causing parameters such as the electronic tag's impedance to change accordingly.

[0112] Load modulation technology mainly includes resistance load modulation and capacitance load modulation. Figure 4 shows a schematic diagram of resistance load modulation provided by related technology. In resistance load modulation, the load resistor R L The third resistor R3 is connected in parallel, and the switch S based on the binary code control is turned on or off. The on and off of the third resistor R3 will cause the voltage on the circuit to change. The load resistor R L Maintaining a parallel connection relationship with the first capacitor C1, the load resistor R L The first inductor L1 is connected in series with the second resistor R2, and the second resistor R2 is connected in series with the first inductor L1. The first inductor L1 is coupled to the second inductor L2, and the second inductor L2 is connected in series with the second capacitor C2. Amplitude Shift Keying (ASK) can be implemented, that is, the modulation and transmission of the signal is achieved by adjusting the amplitude of the backscattered signal of the zero-power device. Similarly, in capacitive load modulation, the resonant frequency of the circuit can be changed by turning the capacitor on and off, and frequency shift keying (FSK) can be implemented, that is, the modulation and transmission of the signal is achieved by adjusting the operating frequency of the backscattered signal of the zero-power device.

[0113] Zero-power devices use load modulation to modulate incoming signals, enabling backscatter communication. These devices offer significant advantages: they don't actively transmit signals, eliminating the need for complex RF links like power amplifiers (PAs) and RF filters. They don't actively generate high-frequency signals, eliminating the need for high-frequency crystal oscillators. Furthermore, backscatter communication allows signal transmission without consuming the device's own energy.

[0114] Extremely low power active transmission technology;

[0115] Zero-power devices can also use ultra-low-power active transmission technology. Unlike backscattering, when using ultra-low-power active transmission technology for data transmission, the device uses a relatively simple and low-power oscillator to generate the RF carrier, and then modulates the information to be transmitted onto the RF carrier. Based on current research, the power consumption of ultra-low-power active transmitters can be as low as hundreds of microwatts, thus achieving ultra-low-power data transmission.

[0116] Next, the encoding method of zero-power communication is introduced:

[0117] FIG5 is a schematic diagram of an encoding method provided by related art. The data transmitted by the electronic tag can use different forms of codes to represent binary "1" and "0". Wireless radio frequency identification systems generally use one of the following encoding methods: Not Return to Zero (NRZ) encoding, Manchester encoding, Unipolar Return to Zero (URZ) encoding, Differential Binary Phase (DBP) encoding, Miller encoding, and differential encoding. That is, different pulse signals can be used to represent 0 and 1.

[0118] ·NRZ encoding; Inverse non-return-to-zero encoding uses a high level to represent a binary "1" and a low level to represent a binary "0". Figure 5 shows a level diagram of encoding binary data: 101100101001011 using the NRZ method.

[0119] Manchester encoding: Manchester encoding is also known as split-phase coding. In Manchester encoding, a binary value is represented by a voltage level change (rising or falling) during half a bit period within the bit length. A negative transition during half a bit period represents a binary "1," and a positive transition during half a bit period represents a binary "0." Data transmission errors occur when multiple tags simultaneously transmit data bits with different values, causing the received rising and falling edges to cancel each other, resulting in an uninterrupted carrier signal throughout the entire bit length. Manchester encoding makes it impossible to have an unchanging state within the bit length. The reader can use this error to determine the specific location of the collision. Manchester encoding facilitates data transmission error detection and is commonly used for data transmission from tags to readers when using carrier load modulation or backscatter modulation. Figure 5 shows a schematic diagram of the voltage levels for binary data 101100101001011 encoded using the Manchester method.

[0120] ·URZ encoding; unipolar return-to-zero encoding: a high level in the first half of the bit period represents a binary "1", while a low level signal that lasts throughout the entire bit period represents a binary "1". Figure 5 shows a level diagram of encoding binary data: 101100101001011 using the URZ method.

[0121] DBP encoding: Differential biphase encoding uses any edge within half a bit period to represent a binary "0," while the absence of an edge represents a binary "1." Furthermore, the voltage level is inverted at the beginning of each bit period. This makes the bit beat easier for the receiver to reconstruct. Figure 5 shows the voltage levels of the binary data 101100101001011 encoded using the DBP method.

[0122] Miller coding: In Miller coding, any edge within half a bit period represents a binary "1," while a constant level throughout the next bit period represents a binary "0." The level transition at the beginning of a bit period makes it easier for the receiver to reconstruct the bit beat. Figure 5 shows the level diagram of the binary data 101100101001011 encoded using the Miller method.

[0123] Differential encoding: In differential encoding, each transmitted binary "1" causes a change in the signal level, while for a binary "0" the signal level remains unchanged.

[0124] Next, we will introduce the classification of zero-power devices:

[0125] Based on the energy source and usage of zero-power devices, zero-power devices can be divided into the following types:

[0126] Passive zero-power devices;

[0127] Zero-power devices do not require internal batteries. When they approach a network device, they are within the near field generated by the network device's antenna radiation. For example, the network device is a reader / writer in a radio frequency identification (RFID) system. Therefore, the zero-power device's antenna generates an induced current through electromagnetic induction, which drives the device's low-power chip circuitry. This enables tasks such as demodulating forward link signals and modulating reverse link signals. For backscatter links, the zero-power device can use backscatter or extremely low-power active transmission to transmit signals. Passive zero-power devices do not require internal batteries for either the forward or reverse link, making them truly zero-power devices. Passive zero-power devices do not require batteries, and their RF and baseband circuits are very simple. For example, they do not require components such as LNAs, PAs, crystal oscillators, and analog-to-digital converters (ADCs). They offer numerous advantages, including small size, light weight, very low price, and a long service life.

[0128] Semi-passive zero-power device;

[0129] Semi-passive zero-power devices lack conventional batteries. Instead, they use a radio frequency energy harvesting module to harvest radio wave energy and store it in an energy storage unit, typically a capacitor. This energy is then used to power the device's low-power chip circuitry, enabling tasks such as demodulating forward link signals and modulating backward link signals. For backscatter links, the device can transmit signals using either backscatter or extremely low-power active transmission.

[0130] Semi-passive zero-power devices require no internal batteries for either the forward or reverse link. Instead, the energy stored in the capacitors is harvested by the radio energy harvesting module, making them truly zero-power devices. They inherit many of the advantages of passive zero-power devices, including small size, light weight, very low price, and long service life.

[0131] Active zero-power devices;

[0132] Zero-power devices used in some scenarios can also be active zero-power devices, which can have built-in batteries. The battery is used to drive the low-power chip circuit of the zero-power device. This enables tasks such as demodulating forward link signals and modulating reverse link signals. However, for backscatter links, zero-power devices can use backscatter or extremely low-power active transmission to transmit signals. Therefore, the zero-power of active zero-power devices is mainly reflected in the fact that reverse link signal transmission does not consume the zero-power device's own power, but instead uses backscatter. In active zero-power devices, the built-in battery powers the RFID chip, increasing the tag's read and write distance and improving communication reliability. Therefore, they are used in scenarios with relatively high requirements for communication distance and read latency.

[0133] Next, we will introduce the classification of zero-power devices based on transmitter type:

[0134] (1) Zero-power devices based on backscattering;

[0135] These zero-power devices use backscattering, as described above, for uplink data transmission. They lack active transmitters, only backscattering transmitters. Therefore, when these zero-power devices transmit uplink data, they require network equipment to provide a carrier. These zero-power devices use backscattering based on the carrier to achieve uplink data transmission.

[0136] (2) Zero-power devices based on active transmitters;

[0137] These zero-power devices use active transmitters with active transmission capabilities for uplink data transmission. Therefore, when sending uplink data, these zero-power devices can use their own active transmitters to send uplink data without the need for network equipment to provide a carrier. Examples of active transmitters suitable for zero-power devices include ultra-low-power ASK transmitters and ultra-low-power FSK transmitters. Based on current implementations, these transmitters can reduce overall power consumption to 400-600 microwatts when transmitting a 100-microwatt signal.

[0138] (3) Zero-power devices that have both backscatter and active transmitters;

[0139] These zero-power devices can support both backscatter and active transmitters. They can determine whether to use backscatter or active transmitters based on different situations (such as varying battery levels, available ambient energy), or based on network device scheduling.

[0140] Next, let’s introduce the cellular Internet of Things:

[0141] Cellular IoT is booming. The 3rd Generation Partnership Project (3GPP) has standardized IoT technologies such as NarrowBand-Internet of Things (NB-IoT), Machine-Type Communications (MTC), and RedCap. However, IoT communication needs in many scenarios remain unmet. For example:

[0142] Harsh communication environment;

[0143] Certain IoT scenarios may encounter 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, IoT devices will not function due to the operating environment limitations of conventional power supplies. Furthermore, extreme operating environments are not conducive to IoT device maintenance, such as battery replacement.

[0144] ·Requirement for extremely small terminal form factor;

[0145] 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 use electronic tags, which are embedded in the product packaging in a very compact form factor. Another example is lightweight wearable IoT terminals that can meet user needs while improving the user experience.

[0146] Extremely low-cost IoT communication requirements;

[0147] Many IoT communication scenarios require IoT terminal devices to be sufficiently low-cost to enhance their competitiveness compared to alternative technologies. For example, in logistics or warehousing scenarios, IoT terminal devices can be attached to each item to facilitate the management of large quantities of circulating items. Communication between the IoT terminal device and the logistics network enables precise management of the entire logistics process and lifecycle. These scenarios require IoT terminal devices to be sufficiently competitively priced.

[0148] Therefore, in order to cover these unmet IoT communication needs, cellular IoT also needs to develop ultra-low-cost, extremely small-size, battery-free / maintenance-free IoT, and zero-power IoT can just meet these needs.

[0149] Zero-power IoT, also known as Ambient IoT or passive IoT, refers to IoT devices that use various environmental energies, such as radio frequency energy, light energy, solar energy, thermal energy, and mechanical energy, to power themselves. 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). Compared to existing IoT devices, Ambient IoT devices offer many advantages, including no conventional batteries, no maintenance, small size, low complexity, low cost, and a long lifespan.

[0150] Zero-power IoT can be used in at least four scenarios:

[0151] (1) Object recognition, such as logistics, production line product management, and supply chain management;

[0152] (2) Environmental monitoring, such as temperature, humidity, and harmful gas monitoring of the working environment and natural environment;

[0153] (3) Positioning, such as indoor positioning, intelligent object search, and production line item positioning;

[0154] (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).

[0155] Next, we will introduce the communication process of Ambient IoT devices:

[0156] In the future, cellular passive IoT or WLAN passive IoT, or Ambient IoT devices, new Ambient IoT devices (electronic devices) can be supported, thereby meeting the corresponding types of IoT communication needs in different application scenarios.

[0157] In actual deployment scenarios, supporting these electronic devices requires APs capable of communicating with them. However, in some application scenarios, a large number of APs supporting traditional technologies have already been deployed. If these APs can support electronic devices that can function in the environment, traditional communication functions can be maintained while reducing power consumption during communication, fully utilizing these deployed APs and reducing physical and financial resource consumption.

[0158] Figure 6 shows a schematic diagram of the communication process of an Ambient IoT device, provided by an exemplary embodiment of the present application. As a new type of Ambient IoT device, electronic device 610 is capable of communicating data with network device 620 in a WiFi system. It can be deployed within the WiFi system, fully utilizing existing network infrastructure and reducing network deployment costs.

[0159] However, since the network device 620 in the WiFi system generally does not have functions such as wireless power supply, a new network node is deployed, such as the power supply node 630 in FIG6 , which may also be called an auxiliary node, for providing wireless power supply to the electronic device 610. The network device 620 in the WiFi system may be an AP.

[0160] Next, the wake-up receiver is introduced:

[0161] 7 shows a schematic diagram of a receiver system 700 provided by the related art. The receiver system 700 includes a first receiver 710 and a main transceiver 720. The first receiver 710 may be referred to as a wake-up receiver (WUR).

[0162] In some embodiments, the main radio 720 can be equivalently understood as a main transceiver, or a main air interface communication unit.

[0163] In some embodiments, the primary transceiver 720 includes a receiver.

[0164] In some embodiments, the primary transceiver 720 includes a receiver and a transmitter.

[0165] In order to further save power, WUR is introduced to receive energy-saving signals. The wake-up receiver has the characteristics of extremely low cost, extremely low complexity and extremely low power consumption. It mainly receives energy-saving signals through envelope detection. Therefore, the energy-saving signal received by the wake-up receiver is different from the modulation method, waveform, etc. of the signal carried by the physical downlink control channel (PDCCH) defined in the relevant standards. The energy-saving signal is mainly an envelope signal that performs ASK modulation on the carrier signal. The demodulation of the envelope signal can also be completed by driving the low-power circuit with the energy provided by the wireless radio frequency signal, so it can be passive. The wake-up receiver can also be actively powered by an electronic device (terminal device). Regardless of the power supply method, the receiver greatly reduces power consumption compared to traditional receivers. For example, WUR can achieve power consumption of less than 1 milliwatt, which is much lower than the power consumption of tens to hundreds of milliwatts of the main receiver. The wake-up receiver can be combined with an electronic device as an additional module of the receiver of the electronic device, or it can be used alone as a wake-up function module of an electronic device.

[0166] As shown in Figure 7, in the initial state, the first receiver 710 is awake and the main transceiver 720 is off. The first receiver 710 receives a power-saving signal and, based on the power-saving signal, determines whether to wake up the main transceiver 720. If awakening the main transceiver 720 is necessary, the network device or power supply node may transmit a power-saving signal instructing awakening to the first receiver 710. Upon receiving the power-saving signal, the first receiver 710 awakens the main transceiver 720. Otherwise, the main transceiver 720 remains off.

[0167] In some embodiments, when the energy saving signal is sent, it is used to indicate wake-up; when the energy saving signal is not sent, it is used to indicate not wake-up.

[0168] In some embodiments, when a power-saving signal carrying a wake-up instruction is sent, it is used to instruct wake-up; when a power-saving signal carrying a non-wake-up instruction is sent, it is used to instruct non-wake-up.

[0169] Therefore, the electronic device can use the first receiver 710 to monitor the energy-saving signal. When the electronic device has no business or no paging message, the electronic device can always use the first receiver 710. Only when the electronic device has business, it receives the energy-saving signal and wakes up the main transceiver 720 to transmit and receive data. Therefore, compared with the traditional mode of always using the main transceiver 720 for data transmission and reception, the power consumption of the electronic device is reduced.

[0170] Next, we will introduce energy harvesting from electronic devices:

[0171] If an electronic device is an Ambient IoT device, it obtains energy from ambient energy. Available ambient energy includes RF energy, solar energy, light energy, thermal energy, kinetic energy, and more. The type of ambient energy used by the electronic device is determined based on the application scenario and operating environment. An electronic device can use one or more types of ambient energy. Because RF energy can be provided by radio waves transmitted through network equipment, and the transmission timing and power are relatively controllable, Ambient IoT devices that use RF energy can be applied in a variety of scenarios.

[0172] If the wireless network is a WiFi network, the network device can be an AP in the WiFi network. Electronic devices can receive radio waves transmitted by the AP to harvest energy. However, APs typically operate at 2.4 GHz or 5 GHz, which have significant radio wave attenuation. Furthermore, due to regulatory requirements, their transmission power is limited. Furthermore, the duration of radio waves transmitted by the AP depends on the needs of services within the network, and there are no clear rules for the timing and duration of transmission. Therefore, directly harvesting energy from the AP's radio waves is often inefficient. To address this issue, a dedicated energy supply node can be deployed to wirelessly power electronic devices.

[0173] The energy supply node can transmit the energy supply signal in a frequency band different from the AP operating frequency band (eg, 2.4 GHz), such as a frequency band below 1 GHz, 920 MHz to 925 MHz.

[0174] The time when the energy supply node transmits the energy supply signal and the duration of transmitting the energy supply signal can be controlled by the signaling sent by the AP, and can also be set by an application program.

[0175] The power supply signal can be a single-frequency sinusoidal wave signal or a broadband modulated signal, and can be a specified waveform such as On-Off Keying (OOK), Orthogonal Frequency Division Multiplexing (OFDM), triangle wave, sine wave or other arbitrary waveforms.

[0176] Electronic devices harvest energy at relatively low power levels, with a current sensitivity of around -20 decibels. This means that electronic devices can only harvest energy when the received energy signal strength is greater than -20 decibels. Assuming a received energy signal strength of -20 decibels, equivalent to 10 microwatts, and an energy harvesting efficiency of 50%, the power harvested by the electronic device is 5 microwatts. Electronic devices can use energy storage devices to store the harvested energy and, when sufficient energy is available, communicate with the network.

[0177] In some embodiments, the electronic device includes a first receiver (wake-up receiver) and a main transceiver (main receiver), and the power consumed by the wake-up receiver (WUR) (typically less than 1 milliwatt) is much lower than the power consumed by the main receiver (typically tens to hundreds of milliwatts). For example, if the power required to keep the main receiver awake is 50 milliwatts and the power required to keep the wake-up receiver awake is 0.5 milliwatts, then the time required for the electronic device to collect energy to keep the main receiver awake is 100 times the time required to collect energy to keep the wake-up receiver awake. Since the power of energy collection is low, waking up the main receiver consumes a lot of energy that the electronic device spends a lot of time collecting. Therefore, when there is no business, the electronic device should not only turn off the main receiver, but also turn off the WUR to save more power.

[0178] To further save energy during communication, an embodiment of the present application provides a receiver wake-up method. FIG8 shows a flowchart of the receiver wake-up method provided by an exemplary embodiment of the present application. The method is performed by an electronic device having a first receiver and a main transceiver. The operating energy consumption of the first receiver is less than the operating energy consumption of the main transceiver. The method includes:

[0179] Step 810: Receive a first energy-saving signal.

[0180] In the initial state, the first receiver and the main transceiver of the electronic device are both in a non-awakened state. This non-awakened state can also be understood as at least one of an off state, a sleep state, and a DRX monitoring state. The sleep state includes at least one of a light sleep state, a deep sleep state, and an ultra-deep sleep state. The light sleep state consumes more power than the deep sleep state, and the deep sleep state consumes more power than the ultra-deep sleep state.

[0181] The first energy-saving signal is used to indicate whether to wake up the first receiver. As an example, the first receiver is a WUR.

[0182] In some embodiments, waking up the first receiver can also be equivalently understood as: monitoring the transmission of downlink data or data frames via the first receiver; or can also be equivalently understood as: monitoring the control channel used to schedule uplink data or downlink data or data frames via the first receiver. The above three expressions have the same meaning in the embodiments of the present application.

[0183] In some embodiments, not waking up the first receiver can also be equivalently understood as keeping the first receiver in an off state; can also be equivalently understood as keeping the first receiver in a sleep state; can also be equivalently understood as keeping the first receiver in a DRX monitoring state. The above four expressions have the same meaning in the embodiments of the present application.

[0184] In some embodiments, the first power-saving signal is used to instruct the first receiver to wake up, which can also be equivalently understood as: the first power-saving signal is used to instruct the first receiver to monitor the transmission of downlink data or data frames; it can also be equivalently understood as: the first power-saving signal is used to instruct the first receiver to monitor the control channel used for scheduling uplink data or downlink data or data frames. The above three expressions have the same meaning in the embodiments of the present application.

[0185] In some embodiments, the first energy-saving signal is used to instruct not to wake up the first receiver. This can also be equivalently understood as: the first energy-saving signal is used to instruct to keep the first receiver in a powered-off state; this can also be equivalently understood as: the first energy-saving signal is used to instruct to keep the first receiver in a sleeping state; this can also be equivalently understood as: the first energy-saving signal is used to instruct to keep the first receiver in a DRX monitoring state. The above four expressions have the same meaning in the embodiments of the present application.

[0186] In some embodiments, the first power-saving signal is received by a first receiver.

[0187] In some embodiments, the electronic device is an active device, which refers to a device that has its own power supply and can actively generate and transmit signals, such as a mobile phone, a computer, a smart watch, a smart bracelet, etc.

[0188] In some embodiments, the electronic device is a passive device, which refers to a device that does not require power supply or can work by receiving energy from other devices. It can be called a zero-power device, a zero-power terminal, a low-power device, a low-power terminal, etc.

[0189] In some embodiments, the electronic device obtains energy from the environment and can be called an ambient energy IoT device.

[0190] In some embodiments, electronic devices are deployed at fixed locations, which may be referred to as zero-power sites, low-power sites, etc.

[0191] In some embodiments, the first energy-saving signal for instructing wake-up and the first energy-saving signal for instructing not to wake-up differ from each other in at least one of the following ways:

[0192] Different waveforms;

[0193] Different modulation methods;

[0194] Sequence lengths vary;

[0195] Different sequences;

[0196] Different frequencies used;

[0197] Different frequency ranges used;

[0198] The values ​​of the information bits carried are different.

[0199] For example, the first energy-saving signal has a first sequence or a second sequence, the first sequence being used to indicate waking up the first receiver, and the second sequence being used to indicate not waking up the first receiver. For example, the first sequence is ZC sequence (Zadoff-Chu sequence) 1, which is used to indicate waking up the first receiver, and the second sequence is ZC sequence 2, which is used to indicate not waking up the first receiver; this is not limited in the embodiments of the present application.

[0200] For another example, the first energy-saving signal has a first sequence length or a second sequence length, the first sequence length being used to indicate waking up the first receiver, and the second sequence length being used to indicate not waking up the first receiver. For example, the first sequence length is 16 bits, which is used to indicate waking up the first receiver, and the second sequence length is 8 bits, which is used to indicate not waking up the first receiver; or the first sequence length is 8 bits, which is used to indicate waking up the first receiver, and the second sequence length is 16 bits, which is used to indicate not waking up the first receiver; this embodiment of the present application is not limited to this.

[0201] In some embodiments, the first energy-saving signal is a wake-up signal. The network device sends a dedicated wake-up signal to the electronic device, where the dedicated wake-up signal is a signal different from the power supply signal.

[0202] In some embodiments, the first energy-saving signal is a power supply signal, and the first energy-saving signal is sent by a network device or a power supply node.

[0203] Since the network device cannot wake up the electronic device by sending signals to the WUR (first receiver) and the main transceiver when both are in the off state, the WUR can be woken up by sending a power supply signal.

[0204] In some embodiments, the first energy-saving signal for indicating not to wake up has a first waveform. For example, the first energy-saving signal is a single-frequency sine wave, and no information is modulated on the single-frequency sine wave.

[0205] In some embodiments, the first energy-saving signal for indicating wake-up is a sequence modulated using a first modulation method, for example, an OOK modulation sequence such as 111000 or 101010, where 1 represents a high level of OOK and 0 represents a low level of OOK.

[0206] The modulation mode of the first energy-saving signal may also be FSK, Phase Shift Keying (PSK), etc., and the sequence length and sequence may also be other values, which are not limited in the embodiment of the present application.

[0207] In some embodiments, the frequency of sending the first power saving signal is changed to indicate whether to wake up the WUR.

[0208] For example, the first energy-saving signal is sent at a first frequency point or a first frequency range, and the first frequency point or the first frequency range is used to indicate that the WUR is being woken up.

[0209] For another example, the first energy-saving signal is sent at the second frequency point or within the second frequency range, and the indication sent at the second frequency point or within the second frequency range is not to wake up the WUR.

[0210] The first frequency point and the second frequency point may be located in the same frequency band or in different frequency bands. The first frequency range and the second frequency range may be located in the same frequency band or in different frequency bands.

[0211] The electronic device measures the energy of received signals at two frequency points or two frequency ranges through a peripheral circuit, thereby determining whether the first energy-saving signal is sent at the first frequency point or the second frequency point, or determining whether the first energy-saving signal is sent within the first frequency range or the second frequency range.

[0212] In some embodiments, the first energy-saving signal may be received in any of the following two ways:

[0213] Method 1: Receive the first energy-saving signal through the second receiver.

[0214] FIG9 shows a schematic diagram of receiving a first energy-saving signal provided by an exemplary embodiment of the present application. As shown in FIG9( a ), the electronic device further includes a second receiver 730 , and the electronic device receives the first energy-saving signal through the second receiver 730 ;

[0215] The operating energy consumption of the second receiver 730 is less than that of the first receiver 710. For example, the second receiver 730 is an RF-based receiver (RF envelope detection receiver), while the first receiver 710 is an intermediate frequency (IF)-based receiver. Therefore, the power consumption of the second receiver 730 is a few microwatts, for example, 5 microwatts, while the power consumption of the first receiver 710 is hundreds of microwatts, for example, 100 microwatts. Therefore, the operating energy consumption of the second receiver 730 is less than that of the first receiver 710.

[0216] In some embodiments, the second receiver 730 and the first receiver 710 are on the same chip or on different chips and are connected via electronic wires.

[0217] Method 2: receiving the first energy-saving signal through the first circuit.

[0218] As shown in FIG9( b ), the electronic device further includes a first circuit 740 , and the electronic device receives the first energy-saving signal through the first circuit 740 .

[0219] In some embodiments, the first circuit 740 includes a wireless energy harvesting circuit of an electronic device, or a peripheral circuit of the first receiver 710 .

[0220] The wireless energy harvesting circuit is used for performing wireless energy harvesting. When the first receiver 710 and the main transceiver 720 are both turned off, the wireless energy harvesting circuit remains in operation and continues to perform wireless energy harvesting.

[0221] The electronic device measures the received signal energy at two frequency points or two frequency ranges through the first circuit 740, thereby determining whether the first energy-saving signal is sent at the first frequency point or the second frequency point, or determining whether the first energy-saving signal is sent within the first frequency range or the second frequency range.

[0222] In some embodiments, the first receiver uses first receiver parameters, the first receiver parameters including a first receiver type and / or a first reception bandwidth.

[0223] The receiver type indicates the type of receiver architecture used by the electronic device, such as a radio frequency (RF)-based receiver or an intermediate frequency (zero intermediate frequency)-based receiver; the receiving bandwidth indicates the bandwidth used to receive signals.

[0224] In some embodiments, the first receiver type is an RF-based receiver type. Using the first receiver of the RF-based receiver type (RF envelope detection receiver type) directly detects the RF signal, eliminating the need for frequency conversion of the RF signal and converting it to a baseband signal, thereby reducing power consumption of the first receiver.

[0225] Since this receiver type can only receive the first energy-saving signal within a specified frequency range based on the implemented RF filter or matching network parameters, the first energy-saving signal can be received on the first frequency band or the first channel within the first frequency band.

[0226] In some embodiments, a first power-saving signal is received within a first frequency band.

[0227] The receiving bandwidth of the first receiver is equal to the bandwidth of the first frequency band, and the first receiver receives the first energy-saving signal within a bandwidth range not exceeding the first frequency band, for example, the first energy-saving signal is received at 920 MHz to 925 MHz.

[0228] In some embodiments, a first power-saving signal is received on a first channel within a first frequency band.

[0229] When the first frequency band includes multiple channels, the first energy-saving signal is received on one of the channels (the first channel), and the receiving bandwidth of the first receiver is equal to the bandwidth of the first channel. For example, 20 channels with a bandwidth of 250 kHz are allocated within the 920 MHz to 925 MHz frequency band, and the first energy-saving signal is received on the first channel.

[0230] For another example, when operating at 2.4 GHz, the frequency band is 2400 MHz to 2485 MHz, which can be divided into multiple channels, such as a channel from 2400 MHz to 2420 MHz, a channel from 2420 MHz to 2440 MHz, a channel from 2440 MHz to 2460 MHz, etc. Therefore, the first energy-saving signal can be received on a first channel within the frequency band, such as a channel from 2400 MHz to 2420 MHz.

[0231] In some embodiments, the first channel is any channel within the first frequency band; or,

[0232] The first channel is a designated channel in the first frequency band; or,

[0233] The first channel is the centralmost channel in the first frequency band; or

[0234] The first channel is one of the two central channels in the first frequency band.

[0235] When the number of channels included in the first frequency band is an odd number, the first channel is the most central channel in the first frequency band; when the number of channels included in the first frequency band is an even number, the first channel is one of the two most central channels in the first frequency band.

[0236] Exemplarily, when the first frequency band includes five channels, the first channel is the most central channel (the third channel); or, when the first frequency band includes four channels, the first channel is one of the two most central channels (the second channel or the third channel).

[0237] Step 830: Receive a second energy-saving signal.

[0238] The second energy-saving signal is used to indicate whether to wake up the main transceiver.

[0239] In some embodiments, step 830 may also be performed before step 810. In the embodiment of the present application, step 810 is performed first and then step 830 is performed as an example for explanation.

[0240] In some embodiments, waking up the main transceiver can also be equivalently understood as waking up the main transceiver; or can also be equivalently understood as waking up the main air interface communication unit. The above three expressions have the same meaning in the embodiments of the present application.

[0241] In some embodiments, waking up the master transceiver can also be equivalently understood as: monitoring the transmission of downlink data or data frames through the master transceiver; or equivalently understood as: monitoring the control channel used to schedule uplink data or downlink data or data frames through the master transceiver. The above three expressions have the same meaning in the embodiments of the present application.

[0242] In some embodiments, not waking up the primary transceiver can also be equivalently understood as keeping the primary transceiver in a powered-off state; or can also be equivalently understood as keeping the primary transceiver in a DRX monitoring state. The above three expressions have the same meaning in the embodiments of the present application.

[0243] In some embodiments, the second energy-saving signal for instructing wake-up and the second energy-saving signal for instructing not to wake-up differ from each other in at least one of the following ways:

[0244] Different waveforms;

[0245] Different modulation methods;

[0246] Sequence lengths vary;

[0247] Different sequences;

[0248] Different frequencies used;

[0249] Different frequency ranges used;

[0250] The values ​​of the information bits carried are different.

[0251] For example, the first energy-saving signal has a first sequence or a second sequence, the first sequence being used to indicate waking up the first receiver, and the second sequence being used to indicate not waking up the first receiver. For example, the first sequence is ZC sequence (Zadoff-Chu sequence) 1, which is used to indicate waking up the first receiver, and the second sequence is ZC sequence 2, which is used to indicate not waking up the first receiver; this is not limited in the embodiments of the present application.

[0252] For another example, the first energy-saving signal has a first sequence length or a second sequence length, the first sequence length being used to indicate waking up the first receiver, and the second sequence length being used to indicate not waking up the first receiver. For example, the first sequence length is 16 bits, which is used to indicate waking up the first receiver, and the second sequence length is 8 bits, which is used to indicate not waking up the first receiver; or the first sequence length is 8 bits, which is used to indicate waking up the first receiver, and the second sequence length is 16 bits, which is used to indicate not waking up the first receiver; this embodiment of the present application is not limited to this.

[0253] In some embodiments, the receiving condition of the second energy-saving signal includes any one of the following two conditions:

[0254] Case 1: After the first receiver wakes up, the second energy-saving signal is received through the first receiver.

[0255] When the first receiver is awakened, it receives the second energy-saving signal, demodulates the second energy-saving signal, and transmits corresponding content to the main transceiver to instruct whether to wake up the main transceiver.

[0256] In some embodiments, "after the first receiver wakes up" can also be equivalently understood as: after the first receiver enters a state of monitoring the transmission of downlink data or data frames; it can also be equivalently understood as: after the first receiver enters a state of monitoring a control channel for scheduling uplink data or downlink data or data frames. The above three expressions have the same meaning in the embodiments of the present application.

[0257] In some embodiments, the first receiver monitors a second energy-saving signal based on a discontinuous reception (DRX) cycle; if the second energy-saving signal associated with the first DRX cycle is monitored, the main transceiver is kept in an awake state or in a non-awakened state during an activation time period in the first DRX cycle according to an indication of the second energy-saving signal associated with the first DRX cycle.

[0258] The second energy-saving signal is sent in either of the following two ways:

[0259] (1) The second energy-saving signal is always sent, and each second energy-saving signal carries a wake-up indication or a non-wake-up indication.

[0260] The first receiver monitors the second energy-saving signal based on the DRX cycle; if the second energy-saving signal associated with the first DRX cycle is monitored, the main transceiver is controlled to be in an awake state during the activation time period of the first DRX cycle according to the wake-up indication carried by the second energy-saving signal; or the main transceiver is kept in a non-awakening state during the activation time period of the first DRX cycle according to the non-wake-up indication carried by the second energy-saving signal.

[0261] (2) The second energy-saving signal is sent on demand, indicating wake-up when sent and not indicating not wake-up when not sent.

[0262] The first receiver monitors the second energy-saving signal based on the DRX cycle; if the second energy-saving signal associated with the first DRX cycle is monitored, the main transceiver is kept in an awake state during the activation time period of the first DRX cycle according to the instruction of the second energy-saving signal associated with the first DRX cycle; if the second energy-saving signal associated with the first DRX cycle is not monitored, the main transceiver is kept in a non-awakened state during the activation time period of the first DRX cycle.

[0263] In some embodiments, the second energy-saving signal associated with the first DRX cycle may be sent before the activation period of the first DRX cycle, or may be sent at an initial position in the activation period of the first DRX cycle.

[0264] Case 2: The second energy-saving signal is received by the main transceiver.

[0265] Wherein, the first receiver and the main transceiver are both in a non-awakening state.

[0266] In some embodiments, the main transceiver monitors a second energy-saving signal based on the DRX cycle; if the second energy-saving signal associated with the first DRX cycle is monitored, the main transceiver is kept in an awake state or in a non-awakened state during the activation time period in the first DRX cycle according to the indication of the second energy-saving signal associated with the first DRX cycle.

[0267] The second energy-saving signal is sent in either of the following two ways:

[0268] (1) The second energy-saving signal is always sent, and each second energy-saving signal carries a wake-up indication or a non-wake-up indication.

[0269] The main transceiver monitors the second energy-saving signal based on the DRX cycle; if the second energy-saving signal associated with the first DRX cycle is monitored, the main transceiver is controlled to be in an awake state during the activation time period in the first DRX cycle according to the wake-up indication carried by the second energy-saving signal; or the main transceiver is kept in a non-awakening state during the activation time period in the first DRX cycle according to the non-wake-up indication carried by the second energy-saving signal.

[0270] (2) The second energy-saving signal is sent on demand, indicating wake-up when sent and not indicating not wake-up when not sent.

[0271] The main transceiver monitors the second energy-saving signal based on the DRX cycle; if the second energy-saving signal associated with the first DRX cycle is monitored, the main transceiver is kept in an awake state during the activation time period of the first DRX cycle according to the instruction of the second energy-saving signal associated with the first DRX cycle; if the second energy-saving signal associated with the first DRX cycle is not monitored, the main transceiver is kept in a non-awakened state during the activation time period of the first DRX cycle.

[0272] In some embodiments, the second energy-saving signal associated with the first DRX cycle may be sent before the activation period of the first DRX cycle, or may be sent at an initial position in the activation period of the first DRX cycle.

[0273] In some embodiments, maintaining the master transceiver in an awake state during the active time period of the first DRX cycle can also be equivalently understood as: monitoring the transmission of downlink data or data frames via the master transceiver during the active time period of the first DRX cycle; or equivalently understood as: monitoring the control channel for scheduling uplink data or downlink data or data frames via the master transceiver during the active time period of the first DRX cycle. The above three expressions have the same meaning in the embodiments of the present application.

[0274] Maintaining the master transceiver in a non-awakened state during the active time period of the first DRX cycle can also be equivalently understood as: during the active time period of the first DRX cycle, the master transceiver does not monitor the transmission of downlink data or data frames; can also be equivalently understood as: during the active time period of the first DRX cycle, the master transceiver does not monitor the control channel used for scheduling uplink data or downlink data or data frames. The above three expressions have the same meaning in the embodiments of the present application.

[0275] A DRX cycle includes "On Duration" and "Opportunity for DRX". During the On Duration (activation time period), the electronic device is in an awake state receiving data, and during the DRX opportunity, the electronic device is in a sleep state not receiving data.

[0276] Exemplarily, the electronic device monitors the second energy-saving signal based on the DRX cycle, and monitors the second energy-saving signal before the activation time period of the first DRX cycle. The second energy-saving signal indicates that the main transceiver is in the awake state. Then, during the activation time period in the first DRX cycle, the main transceiver is kept in the awake state.

[0277] In some embodiments, the first energy-saving signal further carries an identifier of the device to be awakened or an identifier of a group of devices to be awakened.

[0278] In some embodiments, the second energy-saving signal further carries an identifier of the device to be awakened or an identifier of a group of devices to be awakened.

[0279] The identifier of the device group to be awakened, that is, the device group identifier (IDentity document, ID) to be awakened, is the ID of the group where the device to be awakened is located. The group includes at least one device to be awakened.

[0280] Whether the electronic device needs to be awakened is determined based on the ID of the device to be awakened or the group ID of the device to be awakened carried in the first energy-saving signal or the second energy-saving signal. If the ID of the electronic device is the same as the ID of the device to be awakened, the electronic device is awakened; if the ID of the electronic device is different from the ID of the device to be awakened, the electronic device is not awakened. If the group ID of the electronic device is the same as the group ID of the device to be awakened, the electronic device is awakened; if the group ID of the electronic device is different from the group ID of the device to be awakened, the electronic device is awakened.

[0281] In some embodiments, the second energy-saving signal further carries synchronization information, and the synchronization information is used to synchronize the wireless network and the electronic device. Synchronization includes time domain synchronization and / or frequency domain synchronization. The wireless network includes at least one of a WiFi network, a cellular network, and a wireless power supply network.

[0282] In summary, the method provided in this embodiment receives a first energy-saving signal that indicates whether to wake up the first receiver; and receives a second energy-saving signal that indicates whether to wake up the main transceiver. When the first receiver is awakened first and then the main transceiver, the power consumption of the electronic device is reduced compared to always keeping the first receiver awake. For example, if the first receiver consumes 0.5 milliwatts of power to stay awake, and the main transceiver consumes 50 milliwatts of power to stay awake, the electronic device collects energy at a lower power of 50 microwatts. When the first receiver and / or the main transceiver are always awake, the rate of energy consumption is greater than the rate of energy collection. Therefore, in the initial state, both the first receiver and the main transceiver of the electronic device are in an inactive state. When preparing for data transmission, the first receiver, which consumes less power, is awakened first, waiting for the data transmission service to begin. When the data transmission service begins, the main transceiver, which consumes more power, is awakened to begin the data transmission service. This reduces the power consumption of the electronic device compared to always keeping the first receiver and / or the main transceiver awake.

[0283] The method provided in this embodiment further receives the first energy-saving signal through the second receiver or the first circuit. The second receiver or the first circuit consumes less power than the first receiver, thereby saving power of the electronic device.

[0284] The method provided in this embodiment further includes receiving a second energy-saving signal through the first receiver after the first receiver wakes up, demodulating the second energy-saving signal, and transmitting the corresponding content to the main transceiver. Because the operating energy consumption of the first receiver is less than that of the main transceiver, the power consumption of the electronic device is reduced.

[0285] The method provided in this embodiment also monitors the second energy-saving signal based on the DRX cycle. The energy consumption of using the main transceiver based on the DRX mechanism is lower than that of using the first receiver, and the first receiver does not need to be used, so that the first receiver and the main transceiver are decoupled, thereby adapting to different application scenarios.

[0286] Since the first receiver consumes less energy than the main transceiver, transferring part of the main transceiver's work to the first receiver can further save the power of the electronic device. In the related art, the first information is received by the main transceiver. In the embodiment of the present application, the first information is received by the first receiver instead, thereby reducing the power consumption of the electronic device. Figure 10 shows a flowchart of a receiver wake-up method provided by an exemplary embodiment of the present application. The method is performed by an electronic device, which has a first receiver and a main transceiver. The operating energy consumption of the first receiver is less than the operating energy consumption of the main transceiver. The method includes:

[0287] Step 810: Receive a first energy-saving signal.

[0288] For specific implementation details, please refer to step 810 of the embodiment of Figure 8, which will not be repeated here.

[0289] Step 820: When the first receiver is in an awake state, receive first information through the first receiver.

[0290] The first information is used for communication between the electronic device and a wireless network, which includes at least one of a WiFi network, a cellular network, and a wireless power supply network.

[0291] In some embodiments, the first information includes information for communication between the first receiver and a wireless network.

[0292] In some embodiments, the electronic device is an active device, which refers to a device that has its own power supply and can actively generate and transmit signals, such as a mobile phone, a computer, a smart watch, a smart bracelet, etc.

[0293] In some embodiments, the electronic device is a passive device, which refers to a device that does not require power supply or can work by receiving energy from other devices. It can be called a zero-power device, a zero-power terminal, a low-power device, a low-power terminal, etc.

[0294] In some embodiments, the electronic device obtains energy from the environment and can be called an ambient energy IoT device.

[0295] In some embodiments, electronic devices are deployed at fixed locations, which may be referred to as zero-power sites, low-power sites, etc.

[0296] In some embodiments, when the first receiver is in an awake state, the network device or the power supply node 630 in the embodiment of Figure 6 sends first information to the first receiver. The first information can be called auxiliary information to help the electronic device quickly establish a connection with the wireless network and complete communication after waking up the main transceiver.

[0297] In some embodiments, the first information includes information used for communication between the primary transceiver and the wireless network. This can also be equivalently understood as the first information including information used for communication between the primary transceiver (or primary air interface communication unit) and the wireless network.

[0298] In some embodiments, the first information includes but is not limited to at least one of the following information:

[0299] Configuration information for receiving downlink data;

[0300] Configuration information for receiving downlink control signaling;

[0301] Used to receive configuration information broadcast by the system;

[0302] Configuration information for sending uplink data;

[0303] Configuration information used to send uplink control signaling;

[0304] Synchronization information for synchronization;

[0305] Configuration information for receiving a second energy-saving signal;

[0306] Wireless network capability information.

[0307] The configuration information for receiving downlink data includes at least one of the following information: a time domain position for receiving downlink data, a frequency position for receiving downlink data, a period for receiving downlink data, etc.;

[0308] The configuration information for receiving downlink control signaling includes at least one of: a time domain location for receiving downlink control signaling, a frequency location for receiving downlink control signaling, a control resource set for monitoring downlink control signaling, a search space set for monitoring downlink control signaling, and a Radio-Network Temporary Identifier (RNTI) for monitoring downlink control signaling;

[0309] The configuration information for receiving the system broadcast includes at least one of the following information: a time domain position of the broadcast frame, a frequency position of the broadcast frame, a broadcast period of the broadcast frame, etc.;

[0310] The configuration information for sending uplink data includes at least one of the following information: a time domain position for sending uplink data, a frequency position for sending uplink data, a period for sending uplink data, etc.;

[0311] The configuration information for sending uplink control signaling includes: at least one of information such as a time domain position for sending uplink control signaling and a frequency position for sending uplink control signaling;

[0312] The synchronization information used for synchronization includes at least one of synchronization information for time domain synchronization and synchronization information for frequency domain synchronization, and helps the first receiver achieve time and frequency synchronization with the wireless network;

[0313] The configuration information for receiving the second energy-saving signal includes at least one of information such as a time domain position for receiving the second energy-saving signal and a frequency position for receiving the second energy-saving signal;

[0314] The capability information of the wireless network includes at least one of the following information: a code rate supported by the wireless network, a modulation and coding scheme (MCS) supported by the wireless network, etc. Such information is generally carried in a beacon frame.

[0315] It should be noted that the above examples of information do not limit the first information. The above first information has different names or definitions in different wireless networks. For example, cellular networks use system information broadcast configuration information, while WiFi networks use beacon frames to broadcast configuration information. Such examples will not be repeated here.

[0316] In some embodiments, the frequency position may be in the form of a channel, a bandwidth, a carrier, etc. For example, downlink data is received on a first channel.

[0317] In some embodiments, the frequency position related information can enable the electronic device to obtain the frequency position when the main transceiver communicates with the wireless network through the first receiver, avoiding the main transceiver from waking up and then scanning to obtain the frequency position, thereby reducing power consumption.

[0318] In some embodiments, the first information is sent via a data frame; or, the first information is sent via a beacon frame.

[0319] In some embodiments, the network device sends the first information first and then sends the second energy-saving signal.

[0320] In some embodiments, the first information is carried in the second power-saving signal.

[0321] After waking up the first receiver, the network device sends a second energy-saving signal. By receiving the second energy-saving signal, the electronic device can simultaneously obtain at least one of the first information, information on whether to wake up the main transceiver, and synchronization information used for synchronization.

[0322] Step 830: Receive a second energy-saving signal.

[0323] For specific implementation details, please refer to step 830 of the embodiment of Figure 8, which will not be repeated here.

[0324] Step 840: When the master transceiver is in the awake state, communicate with the wireless network based on the first information.

[0325] When the main transceiver is in the awake state, the electronic device obtains the configuration of the wireless network based on the content carried by the first information.

[0326] Exemplarily, when the first information includes configuration information for receiving downlink data, the primary transceiver receives the downlink data based on information such as the time domain location and frequency location of the downlink data. Before receiving the downlink data, the primary transceiver may be kept in a non-awakened state as much as possible, thereby further saving power.

[0327] In a case where the first information includes configuration information for receiving downlink control signaling, the downlink control signaling is used to indicate relevant information for receiving downlink data. The master transceiver monitors the downlink control signaling based on the time domain location and frequency location of receiving the downlink control signaling, and receives downlink data according to the relevant information for receiving the downlink data indicated by the downlink control signaling, thereby communicating with the wireless network. By receiving the configuration information in advance, the master transceiver is kept in a non-awakened state for a longer period of time, thereby reducing power consumption of the electronic device.

[0328] When the first information includes configuration information for receiving a system broadcast, the primary transceiver receives the system broadcast of the wireless network based on information such as the time domain position and frequency position of the broadcast frame. By receiving the configuration information of the system broadcast in advance, the primary transceiver can remain in a non-awakened state during the stages of receiving the system broadcast and obtaining the configuration information in the system broadcast, thereby saving power.

[0329] When the first information includes configuration information for sending uplink data, the master transceiver sends the uplink data based on information such as the time domain location and frequency location of the uplink data. Before receiving the uplink data, the master transceiver can be kept in a non-awakened state as much as possible, thereby saving power.

[0330] In the case where the first information includes configuration information for sending uplink control signaling, the uplink control signaling is used to provide feedback on whether downlink data has been received, and the master transceiver monitors the uplink control signaling based on information such as the time domain location and frequency location of the uplink control signaling. By receiving the configuration information in advance, the master transceiver can remain in a non-awakened state for a longer period of time, thereby reducing power consumption of the electronic device.

[0331] When the first information includes synchronization information for synchronization, the electronic device enables the master transceiver to obtain time and frequency synchronization with the wireless network based on the synchronization information for time domain synchronization and / or the synchronization information for frequency domain synchronization, thereby eliminating the need for the master transceiver to wake up and then perform time and frequency synchronization;

[0332] When the first information includes configuration information for receiving the second energy-saving signal, the master transceiver monitors or receives the second energy-saving signal based on information such as the time domain location and frequency location of receiving the second energy-saving signal. By receiving the configuration information in advance, the master transceiver is kept in a non-awakened state for a longer period of time, thereby reducing power consumption of the electronic device.

[0333] When the first information includes wireless network capability information, the primary transceiver communicates with the wireless network based on information such as the bit rate and MCS supported by the wireless network, for example, communicating with the wireless network at a bit rate of 128 kilobits per second. This eliminates the need for the primary transceiver to wake up and read other content, such as a beacon frame, to obtain the capability information, thereby reducing power consumption of the electronic device.

[0334] After receiving the first information, the electronic device uses the primary transceiver to establish a connection or association with the network and then communicate. The primary transceiver uses a communication protocol in related technologies, such as 802.11b and 802.11n, so that the electronic device can communicate with a network device (such as an AP) in related technologies.

[0335] To sum up, the method provided in this embodiment receives the first information through the first receiver when the first receiver is in an awake state. The first information is used for communication between the electronic device and the wireless network, so that the main transceiver of the electronic device does not need to read the first information from the beacon frame after waking up, which can help the electronic device quickly establish a connection with the wireless network and save power of the electronic device.

[0336] Since the working energy consumption of the first receiver is less than that of the main transceiver, the first receiver receives information communicated between the first receiver and the wireless network, which can reduce the power consumption of the electronic device compared to using the main transceiver to receive the above information.

[0337] In some embodiments, the first information includes information for communication between the first receiver and a wireless network.

[0338] In some embodiments, the first information includes at least one of the following:

[0339] Configuration information for receiving downlink data;

[0340] Configuration information for receiving downlink control signaling;

[0341] Used to receive configuration information broadcast by the system;

[0342] Synchronization information for synchronization;

[0343] Configuration information for receiving a first energy-saving signal;

[0344] Configuration information for receiving a second energy-saving signal;

[0345] Wireless network capability information.

[0346] The configuration information for receiving downlink data includes at least one of the following information: a time domain position for receiving downlink data, a frequency position for receiving downlink data, a period for receiving downlink data, etc.;

[0347] The configuration information for receiving downlink control signaling includes: at least one of: a time domain position for receiving downlink control signaling, a frequency position for receiving downlink control signaling, a control resource set for monitoring downlink control signaling, a search space set for monitoring downlink control signaling, and an RNTI for monitoring downlink control signaling;

[0348] The configuration information for receiving the system broadcast includes at least one of the following information: a time domain position of the broadcast frame, a frequency position of the broadcast frame, a broadcast period of the broadcast frame, etc.;

[0349] The synchronization information used for synchronization includes at least one of synchronization information for time domain synchronization and synchronization information for frequency domain synchronization, and helps the first receiver achieve time and frequency synchronization with the wireless network, so that the master transceiver does not need to perform time and frequency synchronization after waking up;

[0350] The configuration information for receiving the first energy-saving signal includes at least one of information such as a time domain position for receiving the first energy-saving signal and a frequency position for receiving the first energy-saving signal;

[0351] The configuration information for receiving the second energy-saving signal includes at least one of information such as a time domain position for receiving the second energy-saving signal and a frequency position for receiving the second energy-saving signal;

[0352] The capability information of the wireless network includes at least one of the bit rate supported by the wireless network, the MCS supported by the wireless network, and other information. This information is generally carried in the beacon frame, so the main transceiver does not need to read the beacon frame after waking up, thereby reducing the power consumption of the electronic device.

[0353] It should be noted that the above examples of information do not limit the first information. The above first information has different names or definitions in different wireless networks. For example, cellular networks use system information broadcast configuration information, while WiFi networks use beacon frames to broadcast configuration information. Such examples will not be repeated here.

[0354] In some embodiments, the first receiver communicates with the wireless network based on the content carried by the first information.

[0355] Exemplarily, when the first information includes configuration information for receiving downlink data, the first receiver receives the downlink data based on information such as a time domain position for receiving the downlink data and a frequency position for receiving the downlink data;

[0356] In a case where the first information includes configuration information for receiving downlink control signaling, the downlink control signaling is used to indicate relevant information for receiving downlink data, the first receiver monitors the downlink control signaling based on a time domain location and a frequency location for receiving the downlink control signaling, and receives the downlink data according to relevant information for receiving the downlink data indicated by the downlink control signaling, thereby communicating with the wireless network;

[0357] In a case where the first information includes configuration information for receiving the system broadcast, the first receiver receives the system broadcast of the wireless network based on information such as a time domain position of the broadcast frame and a frequency position of the broadcast frame;

[0358] In a case where the first information includes synchronization information for synchronization, the first receiver acquires time and frequency synchronization with the wireless network based on the synchronization information for time domain synchronization and / or the synchronization information for frequency domain synchronization;

[0359] In a case where the first information includes configuration information for receiving the first energy-saving signal, the first receiver monitors or receives the first energy-saving signal based on information such as a time domain location for receiving the first energy-saving signal and a frequency location for receiving the first energy-saving signal;

[0360] In a case where the first information includes configuration information for receiving the second energy-saving signal, the first receiver monitors or receives the second energy-saving signal based on information such as a time domain location for receiving the second energy-saving signal and a frequency location for receiving the second energy-saving signal;

[0361] When the first information includes capability information of the wireless network, the first receiver communicates with the wireless network based on information such as the bit rate and MCS supported by the wireless network, for example, at a bit rate of 8 kilobits per second.

[0362] In some embodiments, taking the wireless network as a WiFi network as an example, the first information includes at least one of the following information:

[0363] Network timestamp information when network devices communicate with the master transceiver;

[0364] Frequency location information of the communication channel used by the primary transceiver for communication;

[0365] The time domain location information of the beacon frame;

[0366] Wireless network capability information;

[0367] Synchronization information for synchronization.

[0368] In the case where the first information includes network timestamp information when the network device communicates with the primary transceiver, the electronic device obtains the timestamp information in advance through the first receiver, so that the primary transceiver can obtain the network communication time without reading the beacon frame after waking up. The primary transceiver can be equivalent to a primary transceiver or a primary air interface communication unit;

[0369] When the first information includes frequency position information of a communication channel used by the primary transceiver for communication, the electronic device adjusts the working channel to the frequency position to avoid waking up the primary transceiver and then scanning the frequency of the primary transceiver to obtain the frequency position of the working channel;

[0370] In the case where the first information includes the time domain position information of the beacon frame, the electronic device receives the beacon frame based on the time domain position. For example, at the time domain position of the signal transmission of a non-beacon frame, the electronic device turns off the main transceiver; at the time domain position of the beacon frame transmission, the electronic device turns on the main transceiver, thereby reducing power consumption. At the same time, considering the clock deviation of the electronic device, the main transceiver can be turned on at the first time domain position. The first time domain position is the time domain position of a time margin before the time domain position of the beacon frame transmission. The time margin can be adjusted according to actual conditions.

[0371] In the case where the first information includes capability information of the wireless network, since the capability information of the wireless network is generally carried in a beacon frame, it is possible to avoid the main transceiver from reading the beacon frame after waking up, thereby reducing power consumption of the electronic device;

[0372] In the case that the first information includes synchronization information for synchronization, the first receiver obtains time and frequency synchronization with the wireless network, so that the main transceiver does not need to perform time and frequency synchronization after waking up.

[0373] In some embodiments, the first information includes downlink data, such as data with a data volume lower than a first threshold, or data with a transmission delay requirement lower than a first delay. The first threshold and the first delay are preset values ​​or value ranges.

[0374] In some embodiments, the first information is received by the first receiver. The first receiver receives data with a data volume lower than a first threshold, or data with a transmission delay requirement lower than a first delay, without using a main transceiver for reception, thereby further reducing power consumption of the electronic device.

[0375] To sum up, the method provided in this embodiment receives the first information through the first receiver when the first receiver is in an awake state. The first information is used for communication between the electronic device and the wireless network, and communication with the wireless network is performed through the first receiver without using a main transceiver, thereby saving power of the electronic device.

[0376] FIG11 shows a flowchart of a method for shutting down a receiver provided by an exemplary embodiment of the present application. The method is executed by an electronic device, wherein the electronic device includes a first receiver and a main transceiver, and the operating energy consumption of the first receiver is less than the operating energy consumption of the main transceiver. The method includes:

[0377] Step 1110: When the first condition is met, turn off the main transceiver.

[0378] Since the main transceiver consumes a lot of energy, when the first condition is met, the main transceiver is turned off.

[0379] For example, the electricity consumption of different users is queried through the Internet of Things electricity meter, and after the query is completed, the main transceiver is turned off.

[0380] Step 1120: If the second condition is met, turn off the first receiver.

[0381] Among them, the first condition and the second condition are two different conditions.

[0382] Although the operating energy consumption of the first receiver is less than that of the main transceiver, in order to further save power, the first receiver is turned off when the second condition is met.

[0383] For example, the electricity consumption of different users is queried through the IoT electricity meter, and after the query is completed, the main transceiver is turned off. When feedback information such as confirmation (ACK) information sent by the wireless network is received, the first receiver is turned off.

[0384] To sum up, the method provided in this embodiment turns off the main transceiver when the first condition is met; and turns off the first receiver when the second condition is met, thereby choosing to turn off one receiver or both receivers according to actual conditions, which meets more application scenarios and saves power of electronic devices.

[0385] FIG12 shows a flowchart of a method for shutting down a receiver provided by an exemplary embodiment of the present application. The method is executed by an electronic device, wherein the electronic device includes a first receiver and a main transceiver, and the operating energy consumption of the first receiver is less than the operating energy consumption of the main transceiver. The method includes:

[0386] Step 1210: When the third condition is met, turn off the first receiver and the main transceiver.

[0387] Among them, the third condition is different from the first condition and the second condition of the embodiment of Figure 11.

[0388] In order to further save power, when the third condition is met, the first receiver and the main transceiver are all turned off.

[0389] Exemplarily, when the IoT storage device receives all the item data stored in the warehouse, the first receiver and the main transceiver are all turned off.

[0390] In summary, the method provided in this embodiment further saves power of the electronic device by shutting down the first receiver and the main transceiver when the third condition is met.

[0391] In the above embodiments, step 1110 and step 1120 in the embodiment corresponding to Figure 11 can be implemented separately, or can be implemented in combination with the embodiment corresponding to Figure 8 or the embodiment corresponding to Figure 10 , for example, step 1110 and step 1120 can be performed after step 840, or step 1110 and step 1120 can be performed after step 830.

[0392] The embodiment corresponding to FIG12 may be implemented alone or in combination with the embodiment corresponding to FIG8 or the embodiment corresponding to FIG10 . For example, step 1210 may be performed after step 840 , or step 1210 may be performed after step 830 .

[0393] FIG13 shows a flowchart of a receiver wake-up method provided by an exemplary embodiment of the present application. The method is executed by a network device or a power supply node, and the method includes:

[0394] Step 1310: Send a first energy-saving signal.

[0395] The first energy-saving signal is used to indicate whether to wake up the first receiver. The electronic device comprises a first receiver and a main transceiver, and the working energy consumption of the first receiver is less than the working energy consumption of the main transceiver.

[0396] In some embodiments, the first energy-saving signal for instructing wake-up and the first energy-saving signal for instructing not to wake-up differ from each other in at least one of the following ways:

[0397] The waveform is different;

[0398] Different modulation methods;

[0399] Sequence lengths vary;

[0400] The sequence is different;

[0401] The frequencies used are different;

[0403] The values ​​of the information bits carried are different.

[0404] In some embodiments, the first power saving signal is a wake-up signal.

[0405] In some embodiments, the first energy-saving signal is a power supply signal.

[0406] In some embodiments, the first energy-saving signal is sent by a network device or a power supply node.

[0407] In some embodiments, the electronic device further includes a second receiver, the first energy-saving signal is a signal received by the electronic device through the second receiver, and the operating energy consumption of the second receiver is less than the operating energy consumption of the first receiver.

[0408] In some embodiments, the electronic device further includes a first circuit, and the first power-saving signal is a signal received by the electronic device through the first circuit.

[0409] In some embodiments, the first circuit includes a wireless energy harvesting circuit of an electronic device, or a peripheral circuit of a first receiver.

[0410] In some embodiments, the first power saving signal is a signal received by the electronic device through the first receiver.

[0411] In some embodiments, the first receiver uses first receiver parameters, the first receiver parameters including a first receiver type and / or a first reception bandwidth.

[0412] In some embodiments, the first receiver type is an RF-based receiver type.

[0413] In some embodiments, the first power-saving signal is sent within a first frequency band.

[0414] In some embodiments, the first power-saving signal is sent on a first channel within a first frequency band.

[0415] In some embodiments, the first channel is any channel within the first frequency band; or,

[0416] The first channel is a designated channel in the first frequency band; or,

[0417] The first channel is the centralmost channel in the first frequency band; or

[0418] The first channel is one of the two central channels in the first frequency band.

[0419] Step 1330: Send a second energy-saving signal.

[0420] The second energy-saving signal is used to indicate whether to wake up the main transceiver.

[0421] In some embodiments, after the first receiver wakes up, a second power-saving signal is sent to the first receiver.

[0422] In some embodiments, the second power saving signal is a signal received by the electronic device via the primary transceiver.

[0423] In some embodiments, the second energy-saving signal is a signal that the electronic device monitors based on the DRX cycle; if the electronic device monitors the second energy-saving signal associated with the first DRX cycle, then according to the indication of the second energy-saving signal associated with the first DRX cycle, the main transceiver is kept in an awake state or in a non-awakened state during the activation time period in the first DRX cycle.

[0424] In some embodiments, the primary transceiver is turned off by the electronic device if the first condition is met.

[0425] In some embodiments, the first receiver is turned off by the electronic device if the second condition is met.

[0426] In some embodiments, the first receiver and the primary transceiver are turned off by the electronic device if a third condition is met.

[0427] The specific implementation details of the above receiver wake-up method are shown in the embodiment of FIG8 and will not be repeated here.

[0428] In summary, the method provided in this embodiment transmits a first power-saving signal that indicates whether to wake up the first receiver, and transmits a second power-saving signal that indicates whether to wake up the primary transceiver. When the first receiver is instructed to wake up first and then the primary transceiver, the power consumption of the electronic device is reduced compared to always keeping the first receiver awake.

[0429] FIG14 shows a flowchart of a receiver wake-up method provided by an exemplary embodiment of the present application. The method is executed by a network device or a power supply node, and the method includes:

[0430] Step 1310: Send a first energy-saving signal.

[0431] Step 1320: When the first receiver is in an awake state, send first information to the first receiver.

[0432] The first information is used for communication between the electronic device and the wireless network.

[0433] In some embodiments, the first information includes information for communication between the first receiver and a wireless network.

[0434] In some embodiments, the first information includes at least one of the following:

[0435] Configuration information for receiving downlink data;

[0436] Configuration information for receiving downlink control signaling;

[0437] Used to receive configuration information broadcast by the system;

[0438] Synchronization information for synchronization;

[0439] Configuration information for receiving a first energy-saving signal;

[0440] Configuration information for receiving a second energy-saving signal;

[0441] Wireless network capability information.

[0442] In some embodiments, the first information includes information for communication between the primary transceiver and the wireless network.

[0443] In some embodiments, the first information includes at least one of the following:

[0444] Configuration information for receiving downlink data;

[0445] Configuration information for receiving downlink control signaling;

[0446] Used to receive configuration information broadcast by the system;

[0447] Configuration information for sending uplink data;

[0448] Configuration information for sending uplink control signaling;

[0449] Synchronization information for synchronization;

[0450] Configuration information for receiving a second energy-saving signal;

[0451] Wireless network capability information.

[0452] In some embodiments, the first information is sent via a data frame; or, the first information is sent via a beacon frame.

[0453] In some embodiments, the electronic device communicates with the wireless network based on the first information when the primary transceiver is in an awake state.

[0454] In some embodiments, the first information is carried in the second power-saving signal.

[0455] In some embodiments, the second energy-saving signal further carries an identifier of the device to be awakened or an identifier of a group of devices to be awakened.

[0456] In some embodiments, the second energy-saving signal further carries synchronization information, and the synchronization information is used for synchronization between the wireless network and the electronic device.

[0457] Step 1330: Send a second energy-saving signal.

[0458] The specific implementation details of the above receiver wake-up method are shown in the embodiment of FIG10 and will not be repeated here.

[0459] In summary, the method provided in this embodiment transmits a first power-saving signal that indicates whether to wake up the first receiver, and transmits a second power-saving signal that indicates whether to wake up the primary transceiver. When the first receiver is instructed to wake up first and then the primary transceiver, the power consumption of the electronic device is reduced compared to always keeping the first receiver awake.

[0460] The method provided in this embodiment also sends first information to the first receiver when the first receiver is in an awake state. The first information is used for communication between the electronic device and the wireless network, so that the main transceiver of the electronic device does not need to read the first information from the beacon frame after waking up, which can help the electronic device quickly establish a connection with the wireless network.

[0461] With the continuous evolution of wireless communication technology, IoT technology is applied to all aspects of production and life. Due to the requirements for power consumption and size of the IoT in different scenarios, ultra-low power consumption, extremely small size, and battery-free zero-power IoT has emerged. In different communication scenarios or different communication processes, the electronic device in the zero-power IoT has only a first receiver. In order to save power, the first receiver is usually in a non-awakened state. Figure 15 shows a flowchart of a receiver wake-up method provided by an exemplary embodiment of the present application. The method is executed by an electronic device, and the electronic device has a first receiver. The method includes:

[0462] Step 1510: Receive a first energy-saving signal.

[0463] In the initial state, the first receiver and the main transceiver of the electronic device are both in a non-awakened state. This non-awakened state can also be understood as at least one of an off state, a sleep state, and a DRX monitoring state. The sleep state includes at least one of a light sleep state, a deep sleep state, and an ultra-deep sleep state. The light sleep state consumes more power than the deep sleep state, and the deep sleep state consumes more power than the ultra-deep sleep state.

[0464] The first energy-saving signal is used to indicate whether to wake up the first receiver. As an example, the first receiver is a WUR.

[0465] In some embodiments, waking up the first receiver can also be equivalently understood as: monitoring the transmission of downlink data or data frames via the first receiver; or can also be equivalently understood as: monitoring the control channel used to schedule uplink data or downlink data or data frames via the first receiver. The above three expressions have the same meaning in the embodiments of the present application.

[0466] In some embodiments, not waking up the first receiver can also be equivalently understood as keeping the first receiver in an off state; can also be equivalently understood as keeping the first receiver in a sleep state; can also be equivalently understood as keeping the first receiver in a DRX monitoring state. The above four expressions have the same meaning in the embodiments of the present application.

[0467] In some embodiments, the first power-saving signal is used to instruct the first receiver to wake up, which can also be equivalently understood as: the first power-saving signal is used to instruct the first receiver to monitor the transmission of downlink data or data frames; it can also be equivalently understood as: the first power-saving signal is used to instruct the first receiver to monitor the control channel used for scheduling uplink data or downlink data or data frames. The above three expressions have the same meaning in the embodiments of the present application.

[0468] In some embodiments, the first energy-saving signal is used to instruct not to wake up the first receiver. This can also be equivalently understood as: the first energy-saving signal is used to instruct to keep the first receiver in a powered-off state; this can also be equivalently understood as: the first energy-saving signal is used to instruct to keep the first receiver in a sleeping state; this can also be equivalently understood as: the first energy-saving signal is used to instruct to keep the first receiver in a DRX monitoring state. The above four expressions have the same meaning in the embodiments of the present application.

[0469] In some embodiments, the first power-saving signal is received by a first receiver.

[0470] In some embodiments, the electronic device is an active device, which refers to a device that has its own power supply and can actively generate and transmit signals, such as a mobile phone, a computer, a smart watch, a smart bracelet, etc.

[0471] In some embodiments, the electronic device is a passive device, which refers to a device that does not require power supply or can work by receiving energy from other devices. It can be called a zero-power device, a zero-power terminal, a low-power device, a low-power terminal, etc.

[0472] In some embodiments, the electronic device obtains energy from the environment and can be called an ambient energy IoT device.

[0473] In some embodiments, the electronic device has an energy harvesting module, which is used to harvest ambient energy from the environment, and the ambient energy is used to power the first receiver.

[0474] In some embodiments, electronic devices are deployed at fixed locations, which may be referred to as zero-power sites, low-power sites, etc.

[0475] In some embodiments, the first energy-saving signal for instructing wake-up and the first energy-saving signal for instructing not to wake-up differ from each other in at least one of the following ways:

[0476] Different waveforms;

[0477] Different modulation methods;

[0478] Sequence lengths vary;

[0479] Different sequences;

[0480] Different frequencies used;

[0481] Different frequency ranges used;

[0482] The values ​​of the information bits carried are different.

[0483] For example, the first energy-saving signal has a first sequence or a second sequence, the first sequence being used to indicate waking up the first receiver, and the second sequence being used to indicate not waking up the first receiver. For example, the first sequence is ZC sequence (Zadoff-Chu sequence) 1, which is used to indicate waking up the first receiver, and the second sequence is ZC sequence 2, which is used to indicate not waking up the first receiver; this is not limited in the embodiments of the present application.

[0484] For another example, the first energy-saving signal has a first sequence length or a second sequence length, the first sequence length being used to indicate waking up the first receiver, and the second sequence length being used to indicate not waking up the first receiver. For example, the first sequence length is 16 bits, which is used to indicate waking up the first receiver, and the second sequence length is 8 bits, which is used to indicate not waking up the first receiver; or the first sequence length is 8 bits, which is used to indicate waking up the first receiver, and the second sequence length is 16 bits, which is used to indicate not waking up the first receiver; this embodiment of the present application is not limited to this.

[0485] In some embodiments, the first energy-saving signal is a wake-up signal. The network device sends a dedicated wake-up signal to the electronic device, where the dedicated wake-up signal is a signal different from the power supply signal.

[0486] In some embodiments, the first energy-saving signal is a power supply signal, and the first energy-saving signal is sent by a network device or a power supply node.

[0487] Since the network device cannot wake up the electronic device by sending signals to the WUR (first receiver) and the main transceiver when both are in the off state, the WUR can be woken up by sending a power supply signal.

[0488] In some embodiments, the first energy-saving signal for indicating not to wake up has a first waveform. For example, the first energy-saving signal is a single-frequency sine wave, and no information is modulated on the single-frequency sine wave.

[0489] In some embodiments, the first energy-saving signal for indicating wake-up is a sequence modulated using a first modulation method, for example, an OOK modulation sequence such as 111000 or 101010, where 1 represents a high level of OOK and 0 represents a low level of OOK.

[0490] The modulation mode of the first energy-saving signal may also be FSK, PSK, etc., and the sequence length and sequence may also be other values, which are not limited in the embodiment of the present application.

[0491] In some embodiments, the frequency of sending the first power saving signal is changed to indicate whether to wake up the WUR.

[0492] For example, the first energy-saving signal is sent at a first frequency point or a first frequency range, and the first frequency point or the first frequency range is used to indicate that the WUR is being woken up.

[0493] For another example, the first energy-saving signal is sent at the second frequency point or within the second frequency range, and the indication sent at the second frequency point or within the second frequency range is not to wake up the WUR.

[0494] The first frequency point and the second frequency point may be located in the same frequency band or in different frequency bands. The first frequency range and the second frequency range may be located in the same frequency band or in different frequency bands.

[0495] The electronic device measures the energy of received signals at two frequency points or two frequency ranges through a peripheral circuit, thereby determining whether the first energy-saving signal is sent at the first frequency point or the second frequency point, or determining whether the first energy-saving signal is sent within the first frequency range or the second frequency range.

[0496] In some embodiments, the first energy-saving signal may be received in any of the following two ways:

[0497] Method 1: Receive the first energy-saving signal through the second receiver.

[0498] FIG9 shows a schematic diagram of receiving a first energy-saving signal provided by an exemplary embodiment of the present application. As shown in FIG9( a ), the electronic device further includes a second receiver 730 , and the electronic device receives the first energy-saving signal through the second receiver 730 ;

[0499] The operating energy consumption of the second receiver 730 is less than that of the first receiver 710. For example, the second receiver 730 is an RF-based receiver (RF envelope detection receiver), while the first receiver 710 is an intermediate frequency (IF)-based receiver. Therefore, the power consumption of the second receiver 730 is a few microwatts, for example, 5 microwatts, while the power consumption of the first receiver 710 is hundreds of microwatts, for example, 100 microwatts. Therefore, the operating energy consumption of the second receiver 730 is less than that of the first receiver 710.

[0500] In some embodiments, the second receiver 730 and the first receiver 710 are on the same chip or on different chips and are connected via electronic wires.

[0501] Method 2: receiving the first energy-saving signal through the first circuit.

[0502] As shown in FIG9( b ), the electronic device further includes a first circuit 740 , and the electronic device receives the first energy-saving signal through the first circuit 740 .

[0503] In some embodiments, the first circuit 740 includes a wireless energy harvesting circuit of an electronic device, or a peripheral circuit of the first receiver 710 .

[0504] The wireless energy harvesting circuit is used for performing wireless energy harvesting. When the first receiver 710 and the main transceiver 720 are both turned off, the wireless energy harvesting circuit remains in operation and continues to perform wireless energy harvesting.

[0505] The electronic device measures the received signal energy at two frequency points or two frequency ranges through the first circuit 740, thereby determining whether the first energy-saving signal is sent at the first frequency point or the second frequency point, or determining whether the first energy-saving signal is sent within the first frequency range or the second frequency range.

[0506] In some embodiments, the operating energy consumption of the first receiver is less than a preset threshold. The preset threshold is typically a smaller value than the operating energy consumption of the primary transceiver, such that the operating energy consumption of the first receiver is significantly less than that of the primary transceiver. For example, if the preset threshold is 1 milliwatt, the operating energy consumption of the primary transceiver is 50 milliwatts, and the operating energy consumption of the first receiver is 0.5 milliwatts.

[0507] In some embodiments, the first receiver uses first receiver parameters, the first receiver parameters including a first receiver type and / or a first reception bandwidth.

[0508] The receiver type indicates the type of receiver architecture used by the electronic device, such as an RF-based receiver or an intermediate frequency (zero intermediate frequency)-based receiver; the reception bandwidth indicates the bandwidth used to receive signals.

[0509] In some embodiments, the first receiver type is an RF-based receiver type. Using the first receiver of the RF-based receiver type (RF envelope detection receiver type) directly detects the RF signal, eliminating the need for frequency conversion of the RF signal and converting it to a baseband signal, thereby reducing power consumption of the first receiver.

[0510] Since this receiver type can only receive the first energy-saving signal within a specified frequency range based on the implemented RF filter or matching network parameters, the first energy-saving signal can be received on the first frequency band or the first channel within the first frequency band.

[0511] In some embodiments, a first power-saving signal is received within a first frequency band.

[0512] The receiving bandwidth of the first receiver is equal to the bandwidth of the first frequency band, and the first receiver receives the first energy-saving signal within a bandwidth range not exceeding the first frequency band, for example, the first energy-saving signal is received at 920 MHz to 925 MHz.

[0513] In some embodiments, a first power-saving signal is received on a first channel within a first frequency band.

[0514] When the first frequency band includes multiple channels, the first energy-saving signal is received on one of the channels (the first channel), and the receiving bandwidth of the first receiver is equal to the bandwidth of the first channel. For example, 20 channels with a bandwidth of 250 kHz are allocated within the 920 MHz to 925 MHz frequency band, and the first energy-saving signal is received on the first channel.

[0515] For another example, when operating at 2.4 GHz, the frequency band is 2400 MHz to 2485 MHz, which can be divided into multiple channels, such as a channel from 2400 MHz to 2420 MHz, a channel from 2420 MHz to 2440 MHz, a channel from 2440 MHz to 2460 MHz, etc. Therefore, the first energy-saving signal can be received on a first channel within the frequency band, such as a channel from 2400 MHz to 2420 MHz.

[0516] In some embodiments, the first channel is any channel within the first frequency band; or,

[0517] The first channel is a designated channel in the first frequency band; or,

[0518] The first channel is the centralmost channel in the first frequency band; or

[0519] The first channel is one of the two central channels in the first frequency band.

[0520] When the number of channels included in the first frequency band is an odd number, the first channel is the most central channel in the first frequency band; when the number of channels included in the first frequency band is an even number, the first channel is one of the two most central channels in the first frequency band.

[0521] Exemplarily, when the first frequency band includes five channels, the first channel is the most central channel (the third channel); or, when the first frequency band includes four channels, the first channel is one of the two most central channels (the second channel or the third channel).

[0522] In summary, the method provided in this embodiment receives a first energy-saving signal that indicates whether to wake up the first receiver. When only the low-power receiver needs to work, only the first receiver is woken up, thereby reducing the power consumption of the electronic device.

[0523] FIG16 shows a flowchart of a receiver wake-up method provided by an exemplary embodiment of the present application. The method is performed by an electronic device, wherein the electronic device includes a first receiver and a main transceiver, and the operating energy consumption of the first receiver is less than the operating energy consumption of the main transceiver. The method includes:

[0524] Step 1510: Receive a first energy-saving signal.

[0525] For specific implementation details, please refer to step 1510 of the embodiment of Figure 15, which will not be repeated here.

[0526] Step 1520: When the first receiver is in an awake state, receive first information through the first receiver.

[0527] The first information is used for communication between the electronic device and a wireless network, which includes at least one of a WiFi network, a cellular network, and a wireless power supply network.

[0528] In some embodiments, the first information includes information for communication between the first receiver and a wireless network.

[0529] In some embodiments, the electronic device is an active device, which refers to a device that has its own power supply and can actively generate and transmit signals, such as a mobile phone, a computer, a smart watch, a smart bracelet, etc.

[0530] In some embodiments, the electronic device is a passive device, which refers to a device that does not require power supply or can work by receiving energy from other devices. It can be called a zero-power device, a zero-power terminal, a low-power device, a low-power terminal, etc.

[0531] In some embodiments, the electronic device obtains energy from the environment and can be called an ambient energy IoT device.

[0532] In some embodiments, the electronic device has an energy harvesting module, which is used to harvest ambient energy from the environment, and the ambient energy is used to power the first receiver.

[0533] In some embodiments, electronic devices are deployed at fixed locations, which may be referred to as zero-power sites, low-power sites, etc.

[0534] In some embodiments, when the first receiver is in an awake state, the network device or the power supply node 630 in the embodiment of Figure 6 sends first information to the first receiver. The first information can be called auxiliary information to help the electronic device quickly establish a connection with the wireless network and complete communication after waking up the main transceiver.

[0535] In some embodiments, the first information includes information used for communication between the primary transceiver and the wireless network. This can also be equivalently understood as the first information including information used for communication between the primary transceiver (or primary air interface communication unit) and the wireless network. In some embodiments, the first information includes, but is not limited to, at least one of the following information:

[0536] Configuration information for receiving downlink data;

[0537] Configuration information for receiving downlink control signaling;

[0538] Used to receive configuration information broadcast by the system;

[0539] Configuration information for sending uplink data;

[0540] Configuration information used to send uplink control signaling;

[0541] Synchronization information for synchronization;

[0542] Configuration information for receiving a second energy-saving signal;

[0543] Wireless network capability information.

[0544] The configuration information for receiving downlink data includes at least one of the following information: a time domain position for receiving downlink data, a frequency position for receiving downlink data, a period for receiving downlink data, etc.;

[0545] The configuration information for receiving downlink control signaling includes: at least one of: a time domain position for receiving downlink control signaling, a frequency position for receiving downlink control signaling, a control resource set for monitoring downlink control signaling, a search space set for monitoring downlink control signaling, and an RNTI for monitoring downlink control signaling;

[0547] The configuration information for sending uplink data includes at least one of the following information: a time domain position for sending uplink data, a frequency position for sending uplink data, a period for sending uplink data, etc.;

[0548] The configuration information for sending uplink control signaling includes: at least one of information such as a time domain position for sending uplink control signaling and a frequency position for sending uplink control signaling;

[0549] The synchronization information used for synchronization includes at least one of synchronization information for time domain synchronization and synchronization information for frequency domain synchronization, and helps the first receiver achieve time and frequency synchronization with the wireless network;

[0550] The configuration information for receiving the second energy-saving signal includes: at least one of information such as a time domain position for receiving the second energy-saving signal and a frequency position for receiving the second energy-saving signal; the second energy-saving signal is used to indicate whether to wake up the main transceiver;

[0551] The capability information of the wireless network includes at least one of the following information: the bit rate supported by the wireless network, the MCS supported by the wireless network, etc., and such information is generally carried in a beacon frame.

[0552] It should be noted that the above examples of information do not limit the first information. The above first information has different names or definitions in different wireless networks. For example, cellular networks use system information broadcast configuration information, while WiFi networks use beacon frames to broadcast configuration information. Such examples will not be repeated here.

[0553] In some embodiments, the frequency position may be in the form of a channel, a bandwidth, a carrier, etc. For example, downlink data is received on a first channel.

[0554] In some embodiments, the frequency position related information can enable the electronic device to obtain the frequency position when the main transceiver communicates with the wireless network through the first receiver, avoiding the main transceiver from waking up and then scanning to obtain the frequency position, thereby reducing power consumption.

[0555] In some embodiments, the first information is sent via a data frame; or, the first information is sent via a beacon frame.

[0556] Step 1530: Receive a second energy-saving signal.

[0557] In some embodiments, the electronic device is an active device, which refers to a device that has its own power supply and can actively generate and transmit signals, such as a mobile phone, a computer, a smart watch, a smart bracelet, etc.

[0558] In some embodiments, the electronic device further includes a main transceiver, and the operating energy consumption of the first receiver is less than the operating energy consumption of the main transceiver.

[0559] The second energy-saving signal is used to indicate whether to wake up the main transceiver.

[0560] In some embodiments, step 1530 may also be performed before step 1510. In the embodiment of the present application, step 1510 is performed first and then step 1530 is performed as an example for explanation.

[0561] In some embodiments, waking up the main transceiver can also be equivalently understood as waking up the main transceiver; or can also be equivalently understood as waking up the main air interface communication unit. The above three expressions have the same meaning in the embodiments of the present application.

[0562] In some embodiments, waking up the master transceiver can also be equivalently understood as: monitoring the transmission of downlink data or data frames through the master transceiver; or equivalently understood as: monitoring the control channel used to schedule uplink data or downlink data or data frames through the master transceiver. The above three expressions have the same meaning in the embodiments of the present application.

[0563] In some embodiments, not waking up the primary transceiver can also be equivalently understood as keeping the primary transceiver in a powered-off state; or can also be equivalently understood as keeping the primary transceiver in a DRX monitoring state. The above three expressions have the same meaning in the embodiments of the present application.

[0564] In some embodiments, the second energy-saving signal for instructing wake-up and the second energy-saving signal for instructing not to wake-up differ from each other in at least one of the following ways:

[0565] Different waveforms;

[0566] Different modulation methods;

[0567] Sequence lengths vary;

[0568] Different sequences;

[0569] Different frequencies used;

[0570] Different frequency ranges used;

[0571] The values ​​of the information bits carried are different.

[0572] For example, the first energy-saving signal has a first sequence or a second sequence, the first sequence being used to indicate waking up the first receiver, and the second sequence being used to indicate not waking up the first receiver. For example, the first sequence is ZC sequence (Zadoff-Chu sequence) 1, which is used to indicate waking up the first receiver, and the second sequence is ZC sequence 2, which is used to indicate not waking up the first receiver; this is not limited in the embodiments of the present application.

[0573] For another example, the first energy-saving signal has a first sequence length or a second sequence length, the first sequence length being used to indicate waking up the first receiver, and the second sequence length being used to indicate not waking up the first receiver. For example, the first sequence length is 16 bits, which is used to indicate waking up the first receiver, and the second sequence length is 8 bits, which is used to indicate not waking up the first receiver; or the first sequence length is 8 bits, which is used to indicate waking up the first receiver, and the second sequence length is 16 bits, which is used to indicate not waking up the first receiver; this embodiment of the present application is not limited to this.

[0574] In some embodiments, the receiving condition of the second energy-saving signal includes any one of the following two conditions:

[0575] Case 1: After the first receiver wakes up, the second energy-saving signal is received through the first receiver.

[0576] When the first receiver is awakened, it receives the second energy-saving signal, demodulates the second energy-saving signal, and transmits corresponding content to the main transceiver to instruct whether to wake up the main transceiver.

[0577] In some embodiments, "after the first receiver wakes up" can also be equivalently understood as: after the first receiver enters a state of monitoring the transmission of downlink data or data frames; it can also be equivalently understood as: after the first receiver enters a state of monitoring a control channel for scheduling uplink data or downlink data or data frames. The above three expressions have the same meaning in the embodiments of the present application.

[0578] In some embodiments, the first receiver monitors a second energy-saving signal based on the DRX cycle; if the second energy-saving signal associated with the first DRX cycle is monitored, the main transceiver is kept in an awake state or in a non-awakened state during the activation time period in the first DRX cycle according to the indication of the second energy-saving signal associated with the first DRX cycle.

[0579] The second energy-saving signal is sent in either of the following two ways:

[0580] (1) The second energy-saving signal is always sent, and each second energy-saving signal carries a wake-up indication or a non-wake-up indication.

[0581] The first receiver monitors the second energy-saving signal based on the DRX cycle; if the second energy-saving signal associated with the first DRX cycle is monitored, the main transceiver is controlled to be in an awake state during the activation time period of the first DRX cycle according to the wake-up indication carried by the second energy-saving signal; or the main transceiver is kept in a non-awakening state during the activation time period of the first DRX cycle according to the non-wake-up indication carried by the second energy-saving signal.

[0582] (2) The second energy-saving signal is sent on demand, indicating wake-up when sent and not indicating not wake-up when not sent.

[0583] The first receiver monitors the second energy-saving signal based on the DRX cycle; if the second energy-saving signal associated with the first DRX cycle is monitored, the main transceiver is kept in an awake state during the activation time period of the first DRX cycle according to the instruction of the second energy-saving signal associated with the first DRX cycle; if the second energy-saving signal associated with the first DRX cycle is not monitored, the main transceiver is kept in a non-awakened state during the activation time period of the first DRX cycle.

[0584] In some embodiments, the second energy-saving signal associated with the first DRX cycle may be sent before the activation period of the first DRX cycle, or may be sent at an initial position in the activation period of the first DRX cycle.

[0585] Case 2: The second energy-saving signal is received by the main transceiver.

[0586] Wherein, the first receiver and the main transceiver are both in a non-awakening state.

[0587] In some embodiments, the main transceiver monitors a second energy-saving signal based on the DRX cycle; if the second energy-saving signal associated with the first DRX cycle is monitored, the main transceiver is kept in an awake state or in a non-awakened state during the activation time period in the first DRX cycle according to the indication of the second energy-saving signal associated with the first DRX cycle.

[0588] The second energy-saving signal is sent in either of the following two ways:

[0589] (1) The second energy-saving signal is always sent, and each second energy-saving signal carries a wake-up indication or a non-wake-up indication.

[0590] The main transceiver monitors the second energy-saving signal based on the DRX cycle; if the second energy-saving signal associated with the first DRX cycle is monitored, the main transceiver is controlled to be in an awake state during the activation time period in the first DRX cycle according to the wake-up indication carried by the second energy-saving signal; or the main transceiver is kept in a non-awakening state during the activation time period in the first DRX cycle according to the non-wake-up indication carried by the second energy-saving signal.

[0591] (2) The second energy-saving signal is sent on demand, indicating wake-up when sent and not indicating not wake-up when not sent.

[0592] The main transceiver monitors the second energy-saving signal based on the DRX cycle; if the second energy-saving signal associated with the first DRX cycle is monitored, the main transceiver is kept in an awake state during the activation time period of the first DRX cycle according to the instruction of the second energy-saving signal associated with the first DRX cycle; if the second energy-saving signal associated with the first DRX cycle is not monitored, the main transceiver is kept in a non-awakened state during the activation time period of the first DRX cycle.

[0593] In some embodiments, the second energy-saving signal associated with the first DRX cycle may be sent before the activation period of the first DRX cycle, or may be sent at an initial position in the activation period of the first DRX cycle.

[0594] In some embodiments, maintaining the master transceiver in an awake state during the active time period of the first DRX cycle can also be equivalently understood as: monitoring the transmission of downlink data or data frames via the master transceiver during the active time period of the first DRX cycle; or equivalently understood as: monitoring the control channel for scheduling uplink data or downlink data or data frames via the master transceiver during the active time period of the first DRX cycle. The above three expressions have the same meaning in the embodiments of the present application.

[0595] Maintaining the master transceiver in a non-awakened state during the active time period of the first DRX cycle can also be equivalently understood as: during the active time period of the first DRX cycle, the master transceiver does not monitor the transmission of downlink data or data frames; can also be equivalently understood as: during the active time period of the first DRX cycle, the master transceiver does not monitor the control channel used for scheduling uplink data or downlink data or data frames. The above three expressions have the same meaning in the embodiments of the present application.

[0596] A DRX cycle includes "On Duration" and "Opportunity for DRX". During the On Duration (activation time period), the electronic device is in an awake state receiving data, and during the DRX opportunity, the electronic device is in a sleep state not receiving data.

[0597] Exemplarily, the electronic device monitors the second energy-saving signal based on the DRX cycle, and monitors the second energy-saving signal before the activation time period of the first DRX cycle. The second energy-saving signal indicates that the main transceiver is in the awake state. Then, during the activation time period in the first DRX cycle, the main transceiver is kept in the awake state.

[0598] In some embodiments, the first energy-saving signal further carries an identifier of the device to be awakened or an identifier of a group of devices to be awakened.

[0599] In some embodiments, the second energy-saving signal further carries an identifier of the device to be awakened or an identifier of a group of devices to be awakened.

[0600] The identifier of the device group to be awakened, that is, the device group ID to be awakened, is the ID of the group where the device to be awakened belongs. The group includes at least one device to be awakened.

[0601] Whether the electronic device needs to be awakened is determined based on the ID of the device to be awakened or the group ID of the device to be awakened carried in the first energy-saving signal or the second energy-saving signal. If the ID of the electronic device is the same as the ID of the device to be awakened, the electronic device is awakened; if the ID of the electronic device is different from the ID of the device to be awakened, the electronic device is not awakened. If the group ID of the electronic device is the same as the group ID of the device to be awakened, the electronic device is awakened; if the group ID of the electronic device is different from the group ID of the device to be awakened, the electronic device is awakened.

[0602] In some embodiments, the second energy-saving signal further carries synchronization information, and the synchronization information is used to synchronize the wireless network and the electronic device. Synchronization includes time domain synchronization and / or frequency domain synchronization. The wireless network includes at least one of a WiFi network, a cellular network, and a wireless power supply network.

[0603] In some embodiments, the network device sends the first information first and then sends the second energy-saving signal.

[0604] In some embodiments, the first information is carried in the second power-saving signal.

[0605] After waking up the first receiver, the network device sends a second energy-saving signal. By receiving the second energy-saving signal, the electronic device can simultaneously obtain at least one of the first information, information on whether to wake up the main transceiver, and synchronization information for synchronization.

[0606] Step 1540: When the master transceiver is in the awake state, communicate with the wireless network based on the first information.

[0607] When the main transceiver is in the awake state, the electronic device obtains the configuration of the wireless network based on the content carried by the first information.

[0608] Exemplarily, when the first information includes configuration information for receiving downlink data, the primary transceiver receives the downlink data based on information such as the time domain location and frequency location of the downlink data. Before receiving the downlink data, the primary transceiver may be kept in a non-awakened state as much as possible, thereby further saving power.

[0609] In a case where the first information includes configuration information for receiving downlink control signaling, the downlink control signaling is used to indicate relevant information for receiving downlink data. The master transceiver monitors the downlink control signaling based on the time domain location and frequency location of receiving the downlink control signaling, and receives downlink data according to the relevant information for receiving the downlink data indicated by the downlink control signaling, thereby communicating with the wireless network. By receiving the configuration information in advance, the master transceiver is kept in a non-awakened state for a longer period of time, thereby reducing power consumption of the electronic device.

[0610] When the first information includes configuration information for receiving a system broadcast, the primary transceiver receives the system broadcast of the wireless network based on information such as the time domain position and frequency position of the broadcast frame. By receiving the configuration information of the system broadcast in advance, the primary transceiver can remain in a non-awakened state during the stages of receiving the system broadcast and obtaining the configuration information in the system broadcast, thereby saving power.

[0611] When the first information includes configuration information for sending uplink data, the master transceiver sends the uplink data based on information such as the time domain location and frequency location of the uplink data. Before receiving the uplink data, the master transceiver can be kept in a non-awakened state as much as possible, thereby saving power.

[0612] In the case where the first information includes configuration information for sending uplink control signaling, the uplink control signaling is used to provide feedback on whether downlink data has been received, and the master transceiver monitors the uplink control signaling based on information such as the time domain location and frequency location of the uplink control signaling. By receiving the configuration information in advance, the master transceiver can remain in a non-awakened state for a longer period of time, thereby reducing power consumption of the electronic device.

[0613] When the first information includes synchronization information for synchronization, the electronic device enables the master transceiver to obtain time and frequency synchronization with the wireless network based on the synchronization information for time domain synchronization and / or the synchronization information for frequency domain synchronization, thereby eliminating the need for the master transceiver to wake up and then perform time and frequency synchronization;

[0614] When the first information includes configuration information for receiving the second energy-saving signal, the master transceiver monitors or receives the second energy-saving signal based on information such as the time domain location and frequency location of receiving the second energy-saving signal. By receiving the configuration information in advance, the master transceiver is kept in a non-awakened state for a longer period of time, thereby reducing power consumption of the electronic device.

[0615] When the first information includes wireless network capability information, the primary transceiver communicates with the wireless network based on information such as the bit rate and MCS supported by the wireless network, for example, communicating with the wireless network at a bit rate of 128 kilobits per second. This eliminates the need for the primary transceiver to wake up and read other content, such as a beacon frame, to obtain the capability information, thereby reducing power consumption of the electronic device.

[0616] After receiving the first information, the electronic device uses the primary transceiver to establish a connection or association with the network and then communicate. The primary transceiver uses a communication protocol in related technologies, such as 802.11b and 802.11n, so that the electronic device can communicate with a network device (such as an AP) in related technologies.

[0617] To sum up, the method provided in this embodiment receives the first information through the first receiver when the first receiver is in an awake state. The first information is used for communication between the electronic device and the wireless network, so that the main transceiver of the electronic device does not need to read the first information from the beacon frame after waking up, which can help the electronic device quickly establish a connection with the wireless network and save power of the electronic device.

[0618] Since the working energy consumption of the first receiver is less than that of the main transceiver, the first receiver receives information communicated between the first receiver and the wireless network, which can reduce the power consumption of the electronic device compared to using the main transceiver to receive the above information.

[0619] In some embodiments, the first information includes information for communication between the first receiver and a wireless network.

[0620] In some embodiments, the first information includes at least one of the following:

[0621] Configuration information for receiving downlink data;

[0622] Configuration information for receiving downlink control signaling;

[0623] Used to receive configuration information broadcast by the system;

[0624] Synchronization information for synchronization;

[0625] Configuration information for receiving a first energy-saving signal;

[0626] Configuration information for receiving a second energy-saving signal;

[0627] Wireless network capability information.

[0628] The configuration information for receiving downlink data includes at least one of the following information: a time domain position for receiving downlink data, a frequency position for receiving downlink data, a period for receiving downlink data, etc.;

[0629] The configuration information for receiving downlink control signaling includes: at least one of: a time domain position for receiving downlink control signaling, a frequency position for receiving downlink control signaling, a control resource set for monitoring downlink control signaling, a search space set for monitoring downlink control signaling, and an RNTI for monitoring downlink control signaling;

[0630] The configuration information for receiving the system broadcast includes at least one of the following information: a time domain position of the broadcast frame, a frequency position of the broadcast frame, a broadcast period of the broadcast frame, etc.;

[0631] The synchronization information used for synchronization includes at least one of synchronization information for time domain synchronization and synchronization information for frequency domain synchronization, and helps the first receiver achieve time and frequency synchronization with the wireless network, so that the master transceiver does not need to perform time and frequency synchronization after waking up;

[0632] The configuration information for receiving the first energy-saving signal includes at least one of information such as a time domain position for receiving the first energy-saving signal and a frequency position for receiving the first energy-saving signal;

[0633] The configuration information for receiving the second energy-saving signal includes at least one of information such as a time domain position for receiving the second energy-saving signal and a frequency position for receiving the second energy-saving signal;

[0634] The capability information of the wireless network includes at least one of the bit rate supported by the wireless network, the MCS supported by the wireless network, and other information. This information is generally carried in the beacon frame, so the main transceiver does not need to read the beacon frame after waking up, thereby reducing the power consumption of the electronic device.

[0635] It should be noted that the above examples of information do not limit the first information. The above first information has different names or definitions in different wireless networks. For example, cellular networks use system information broadcast configuration information, while WiFi networks use beacon frames to broadcast configuration information. Such examples will not be repeated here.

[0636] In some embodiments, the first receiver communicates with the wireless network based on the content carried by the first information.

[0637] Exemplarily, when the first information includes configuration information for receiving downlink data, the first receiver receives the downlink data based on information such as a time domain position for receiving the downlink data and a frequency position for receiving the downlink data;

[0638] In a case where the first information includes configuration information for receiving downlink control signaling, the downlink control signaling is used to indicate relevant information for receiving downlink data, the first receiver monitors the downlink control signaling based on a time domain location and a frequency location for receiving the downlink control signaling, and receives the downlink data according to relevant information for receiving the downlink data indicated by the downlink control signaling, thereby communicating with the wireless network;

[0639] In a case where the first information includes configuration information for receiving the system broadcast, the first receiver receives the system broadcast of the wireless network based on information such as a time domain position of the broadcast frame and a frequency position of the broadcast frame;

[0640] In a case where the first information includes synchronization information for synchronization, the first receiver acquires time and frequency synchronization with the wireless network based on the synchronization information for time domain synchronization and / or the synchronization information for frequency domain synchronization;

[0641] In a case where the first information includes configuration information for receiving the first energy-saving signal, the first receiver monitors or receives the first energy-saving signal based on information such as a time domain location for receiving the first energy-saving signal and a frequency location for receiving the first energy-saving signal;

[0642] In a case where the first information includes configuration information for receiving the second energy-saving signal, the first receiver monitors or receives the second energy-saving signal based on information such as a time domain location for receiving the second energy-saving signal and a frequency location for receiving the second energy-saving signal;

[0643] When the first information includes capability information of the wireless network, the first receiver communicates with the wireless network based on information such as the bit rate and MCS supported by the wireless network, for example, at a bit rate of 8 kilobits per second.

[0644] In some embodiments, taking the wireless network as a WiFi network as an example, the first information includes at least one of the following information:

[0645] Network timestamp information when network devices communicate with the master transceiver;

[0646] Frequency location information of the communication channel used by the primary transceiver for communication;

[0647] The time domain location information of the beacon frame;

[0648] Wireless network capability information;

[0649] Synchronization information for synchronization.

[0650] In the case where the first information includes network timestamp information when the network device communicates with the primary transceiver, the electronic device obtains the timestamp information in advance through the first receiver, so that the primary transceiver can obtain the network communication time without reading the beacon frame after waking up. The primary transceiver can be equivalent to a primary transceiver or a primary air interface communication unit;

[0651] When the first information includes frequency position information of a communication channel used by the primary transceiver for communication, the electronic device adjusts the working channel to the frequency position to avoid waking up the primary transceiver and then scanning the frequency of the primary transceiver to obtain the frequency position of the working channel;

[0652] In the case where the first information includes the time domain position information of the beacon frame, the electronic device receives the beacon frame based on the time domain position. For example, at the time domain position of the signal transmission of a non-beacon frame, the electronic device turns off the main transceiver; at the time domain position of the beacon frame transmission, the electronic device turns on the main transceiver, thereby reducing power consumption. At the same time, considering the clock deviation of the electronic device, the main transceiver can be turned on at the first time domain position. The first time domain position is the time domain position of a time margin before the time domain position of the beacon frame transmission. The time margin can be adjusted according to actual conditions.

[0653] In the case where the first information includes capability information of the wireless network, since the capability information of the wireless network is generally carried in a beacon frame, it is possible to avoid the main transceiver from reading the beacon frame after waking up, thereby reducing power consumption of the electronic device;

[0654] In the case that the first information includes synchronization information for synchronization, the first receiver obtains time and frequency synchronization with the wireless network, so that the main transceiver does not need to perform time and frequency synchronization after waking up.

[0655] In some embodiments, the first information includes downlink data, such as data with a data volume lower than a first threshold, or data with a transmission delay requirement lower than a first delay. The first threshold and the first delay are preset values ​​or value ranges.

[0656] In some embodiments, the first information is received by the first receiver. The first receiver receives data with a data volume lower than a first threshold, or data with a transmission delay requirement lower than a first delay, without using a main transceiver for reception, thereby further reducing power consumption of the electronic device.

[0657] To sum up, the method provided in this embodiment receives the first information through the first receiver when the first receiver is in an awake state. The first information is used for communication between the electronic device and the wireless network, and communication with the wireless network is performed through the first receiver without using a main transceiver, thereby saving power of the electronic device.

[0658] In the above embodiments, step 1110 and step 1120 in the embodiment corresponding to Figure 11 can be implemented in combination with the embodiment corresponding to Figure 15 or the embodiment corresponding to Figure 16, for example, step 1110 and step 1120 are performed after step 1540, or step 1110 and step 1120 can be performed after step 1530.

When the first receiver is instructed to wake up first and then the primary transceiver, the power consumption of the electronic device is reduced compared to always keeping the first receiver awake.

[0730] The method provided in this embodiment also sends first information to the first receiver when the first receiver is in an awake state. The first information is used for communication between the electronic device and the wireless network, so that the main transceiver of the electronic device does not need to read the first information from the beacon frame after waking up, which can help the electronic device quickly establish a connection with the wireless network.

[0731] With the continuous evolution of wireless communication technology, IoT technology is applied to all aspects of production and life. In different scenarios, there are different requirements for power consumption and latency of IoT devices. Electronic devices used in IoT often face the problem of slow receiver wake-up speed during communication.

For example, cellular networks use system information broadcast configuration information, while WiFi networks use beacon frames to broadcast configuration information. Such examples will not be repeated here.

[0764] In some embodiments, the frequency position may be in the form of a channel, a bandwidth, a carrier, etc. For example, downlink data is received on a first channel.

[0765] In some embodiments, the frequency position related information can enable the electronic device to obtain the frequency position when the main transceiver communicates with the wireless network through the first receiver, avoiding the main transceiver from waking up and then scanning to obtain the frequency position, thereby reducing power consumption.

[0766] In some embodiments, the first information is sent via a data frame; or, the first information is sent via a beacon frame.

[0767] To sum up, the method provided in this embodiment receives the first information through the first receiver when the first receiver is in an awake state. The first information is used for communication between the electronic device and the wireless network, so that the main transceiver of the electronic device does not need to read the first information from the beacon frame after waking up, which can help the electronic device quickly establish a connection with the wireless network.

[0768] FIG20 shows a flowchart of an information transmission method provided by an exemplary embodiment of the present application. The method is performed by an electronic device, wherein the electronic device includes a first receiver and a main transceiver, wherein the operating energy consumption of the first receiver is less than the operating energy consumption of the main transceiver. The method includes:

[0769] Step 1910: When the first receiver is in an awake state, receive first information through the first receiver.

[0770] For specific implementation details, please refer to step 1910 of the embodiment of Figure 19, which will not be repeated here.

[0771] Step 1920: Receive a second energy-saving signal.

[0772] The second energy-saving signal is used to indicate whether to wake up the main transceiver.

[0773] In some embodiments, waking up the main transceiver can also be equivalently understood as waking up the main transceiver; or can also be equivalently understood as waking up the main air interface communication unit. The above three expressions have the same meaning in the embodiments of the present application.

[0774] In some embodiments, waking up the master transceiver can also be equivalently understood as: monitoring the transmission of downlink data or data frames through the master transceiver; or equivalently understood as: monitoring the control channel used to schedule uplink data or downlink data or data frames through the master transceiver. The above three expressions have the same meaning in the embodiments of the present application.

[0775] In some embodiments, not waking up the primary transceiver can also be equivalently understood as keeping the primary transceiver in a powered-off state; or can also be equivalently understood as keeping the primary transceiver in a DRX monitoring state. The above three expressions have the same meaning in the embodiments of the present application.

[0776] In some embodiments, the second energy-saving signal for instructing wake-up and the second energy-saving signal for instructing not to wake-up differ from each other in at least one of the following ways:

[0777] Different waveforms;

[0778] Different modulation methods;

[0779] Sequence lengths vary;

[0780] Different sequences;

[0781] Different frequencies used;

[0782] Different frequency ranges used;

[0783] The values ​​of the information bits carried are different.

[0784] For example, the first energy-saving signal has a first sequence or a second sequence, the first sequence being used to indicate waking up the first receiver, and the second sequence being used to indicate not waking up the first receiver. For example, the first sequence is ZC sequence (Zadoff-Chu sequence) 1, which is used to indicate waking up the first receiver, and the second sequence is ZC sequence 2, which is used to indicate not waking up the first receiver; this is not limited in the embodiments of the present application.

[0785] For another example, the first energy-saving signal has a first sequence length or a second sequence length, the first sequence length being used to indicate waking up the first receiver, and the second sequence length being used to indicate not waking up the first receiver. For example, the first sequence length is 16 bits, which is used to indicate waking up the first receiver, and the second sequence length is 8 bits, which is used to indicate not waking up the first receiver; or the first sequence length is 8 bits, which is used to indicate waking up the first receiver, and the second sequence length is 16 bits, which is used to indicate not waking up the first receiver; this embodiment of the present application is not limited to this.

[0786] In some embodiments, the receiving condition of the second energy-saving signal includes any one of the following two conditions:

[0787] Case 1: After the first receiver wakes up, the second energy-saving signal is received through the first receiver.

[0788] When the first receiver is awakened, it receives the second energy-saving signal, demodulates the second energy-saving signal, and transmits corresponding content to the main transceiver to instruct whether to wake up the main transceiver.

[0789] In some embodiments, "after the first receiver wakes up" can also be equivalently understood as: after the first receiver enters a state of monitoring the transmission of downlink data or data frames; it can also be equivalently understood as: after the first receiver enters a state of monitoring a control channel for scheduling uplink data or downlink data or data frames. The above three expressions have the same meaning in the embodiments of the present application.

[0790] In some embodiments, the first receiver monitors a second energy-saving signal based on the DRX cycle; if the second energy-saving signal associated with the first DRX cycle is monitored, the main transceiver is kept in an awake state or in a non-awakened state during the activation time period in the first DRX cycle according to the indication of the second energy-saving signal associated with the first DRX cycle.

[0791] The second energy-saving signal is sent in either of the following two ways:

[0792] (1) The second energy-saving signal is always sent, and each second energy-saving signal carries a wake-up indication or a non-wake-up indication.

[0793] The first receiver monitors the second energy-saving signal based on the DRX cycle; if the second energy-saving signal associated with the first DRX cycle is monitored, the main transceiver is controlled to be in an awake state during the activation time period of the first DRX cycle according to the wake-up indication carried by the second energy-saving signal; or the main transceiver is kept in a non-awakening state during the activation time period of the first DRX cycle according to the non-wake-up indication carried by the second energy-saving signal.

[0794] (2) The second energy-saving signal is sent on demand, indicating wake-up when sent and not indicating not wake-up when not sent.

[0795] The first receiver monitors the second energy-saving signal based on the DRX cycle; if the second energy-saving signal associated with the first DRX cycle is monitored, the main transceiver is kept in an awake state during the activation time period of the first DRX cycle according to the instruction of the second energy-saving signal associated with the first DRX cycle; if the second energy-saving signal associated with the first DRX cycle is not monitored, the main transceiver is kept in a non-awakened state during the activation time period of the first DRX cycle.

[0796] In some embodiments, the second energy-saving signal associated with the first DRX cycle may be sent before the activation period of the first DRX cycle, or may be sent at an initial position in the activation period of the first DRX cycle.

[0797] Case 2: The second energy-saving signal is received by the main transceiver.

[0798] Wherein, the first receiver and the main transceiver are both in a non-awakening state.

[0799] In some embodiments, the main transceiver monitors a second energy-saving signal based on the DRX cycle; if the second energy-saving signal associated with the first DRX cycle is monitored, the main transceiver is kept in an awake state or in a non-awakened state during the activation time period in the first DRX cycle according to the indication of the second energy-saving signal associated with the first DRX cycle.

[0800] The second energy-saving signal is sent in either of the following two ways:

[0801] (1) The second energy-saving signal is always sent, and each second energy-saving signal carries a wake-up indication or a non-wake-up indication.

[0802] The main transceiver monitors the second energy-saving signal based on the DRX cycle; if the second energy-saving signal associated with the first DRX cycle is monitored, the main transceiver is controlled to be in an awake state during the activation time period in the first DRX cycle according to the wake-up indication carried by the second energy-saving signal; or the main transceiver is kept in a non-awakening state during the activation time period in the first DRX cycle according to the non-wake-up indication carried by the second energy-saving signal.

[0803] (2) The second energy-saving signal is sent on demand, indicating wake-up when sent and not indicating not wake-up when not sent.

[0804] The main transceiver monitors the second energy-saving signal based on the DRX cycle; if the second energy-saving signal associated with the first DRX cycle is monitored, the main transceiver is kept in an awake state during the activation time period of the first DRX cycle according to the instruction of the second energy-saving signal associated with the first DRX cycle; if the second energy-saving signal associated with the first DRX cycle is not monitored, the main transceiver is kept in a non-awakened state during the activation time period of the first DRX cycle.

[0805] In some embodiments, the second energy-saving signal associated with the first DRX cycle may be sent before the activation period of the first DRX cycle, or may be sent at an initial position in the activation period of the first DRX cycle.

[0806] In some embodiments, maintaining the master transceiver in an awake state during the active time period of the first DRX cycle can also be equivalently understood as: monitoring the transmission of downlink data or data frames via the master transceiver during the active time period of the first DRX cycle; or equivalently understood as: monitoring the control channel for scheduling uplink data or downlink data or data frames via the master transceiver during the active time period of the first DRX cycle. The above three expressions have the same meaning in the embodiments of the present application.

[0807] Maintaining the master transceiver in a non-awakened state during the active time period of the first DRX cycle can also be equivalently understood as: during the active time period of the first DRX cycle, the master transceiver does not monitor the transmission of downlink data or data frames; can also be equivalently understood as: during the active time period of the first DRX cycle, the master transceiver does not monitor the control channel used for scheduling uplink data or downlink data or data frames. The above three expressions have the same meaning in the embodiments of the present application.

[0808] A DRX cycle includes "On Duration" and "Opportunity for DRX". During the On Duration (activation time period), the electronic device is in an awake state receiving data, and during the DRX opportunity, the electronic device is in a sleep state not receiving data.

[0809] Exemplarily, the electronic device monitors the second energy-saving signal based on the DRX cycle, and monitors the second energy-saving signal before the activation time period of the first DRX cycle. The second energy-saving signal indicates that the main transceiver is in the awake state. Then, during the activation time period in the first DRX cycle, the main transceiver is kept in the awake state.

[0810] In some embodiments, the second energy-saving signal further carries an identifier of the device to be awakened or an identifier of a group of devices to be awakened.

[0811] The identifier of the device group to be awakened, that is, the device group ID to be awakened, is the ID of the group where the device to be awakened belongs. The group includes at least one device to be awakened.

[0812] Whether the electronic device needs to be awakened is determined based on the ID of the device to be awakened or the group ID of the device to be awakened carried in the second energy-saving signal. If the ID of the electronic device is the same as the ID of the device to be awakened, the electronic device is awakened; if the ID of the electronic device is different from the ID of the device to be awakened, the electronic device is not awakened. If the group ID of the electronic device is the same as the group ID of the device to be awakened, the electronic device is awakened; if the group ID of the electronic device is different from the group ID of the device to be awakened, the electronic device is not awakened.

[0813] In some embodiments, the second energy-saving signal further carries synchronization information, and the synchronization information is used to synchronize the wireless network and the electronic device. Synchronization includes time domain synchronization and / or frequency domain synchronization. The wireless network includes at least one of a WiFi network, a cellular network, and a wireless power supply network.

[0814] In some embodiments, the network device sends the first information first and then sends the second energy-saving signal.

[0815] In some embodiments, the first information is carried in the second power-saving signal.

[0816] After waking up the first receiver, the network device sends a second energy-saving signal. By receiving the second energy-saving signal, the electronic device can simultaneously obtain at least one of the first information, information on whether to wake up the main transceiver, and synchronization information used for synchronization.

[0817] Step 1930: When the master transceiver is in the awake state, communicate with the wireless network based on the first information.

[0818] When the main transceiver is in the awake state, the electronic device obtains the configuration of the wireless network based on the content carried by the first information.

[0819] Exemplarily, when the first information includes configuration information for receiving downlink data, the primary transceiver receives the downlink data based on information such as the time domain location and frequency location of the downlink data. Before receiving the downlink data, the primary transceiver may be kept in a non-awakened state as much as possible, thereby further saving power.

[0820] In a case where the first information includes configuration information for receiving downlink control signaling, the downlink control signaling is used to indicate relevant information for receiving downlink data. The master transceiver monitors the downlink control signaling based on the time domain location and frequency location of receiving the downlink control signaling, and receives downlink data according to the relevant information for receiving the downlink data indicated by the downlink control signaling, thereby communicating with the wireless network. By receiving the configuration information in advance, the master transceiver is kept in a non-awakened state for a longer period of time, thereby reducing power consumption of the electronic device.

[0821] When the first information includes configuration information for receiving a system broadcast, the primary transceiver receives the system broadcast of the wireless network based on information such as the time domain position and frequency position of the broadcast frame. By receiving the configuration information of the system broadcast in advance, the primary transceiver can remain in a non-awakened state during the stages of receiving the system broadcast and obtaining the configuration information in the system broadcast, thereby saving power.

[0822] When the first information includes configuration information for sending uplink data, the master transceiver sends the uplink data based on information such as the time domain location and frequency location of the uplink data. Before receiving the uplink data, the master transceiver can be kept in a non-awakened state as much as possible, thereby saving power.

[0823] In the case where the first information includes configuration information for sending uplink control signaling, the uplink control signaling is used to provide feedback on whether downlink data has been received, and the master transceiver monitors the uplink control signaling based on information such as the time domain location and frequency location of the uplink control signaling. By receiving the configuration information in advance, the master transceiver can remain in a non-awakened state for a longer period of time, thereby reducing power consumption of the electronic device.

[0824] When the first information includes synchronization information for synchronization, the electronic device enables the master transceiver to obtain time and frequency synchronization with the wireless network based on the synchronization information for time domain synchronization and / or the synchronization information for frequency domain synchronization, thereby eliminating the need for the master transceiver to wake up and then perform time and frequency synchronization;

[0825] When the first information includes configuration information for receiving the second energy-saving signal, the master transceiver monitors or receives the second energy-saving signal based on information such as the time domain location and frequency location of receiving the second energy-saving signal. By receiving the configuration information in advance, the master transceiver is kept in a non-awakened state for a longer period of time, thereby reducing power consumption of the electronic device.

[0826] When the first information includes wireless network capability information, the primary transceiver communicates with the wireless network based on information such as the bit rate and MCS supported by the wireless network, for example, communicating with the wireless network at a bit rate of 128 kilobits per second. This eliminates the need for the primary transceiver to wake up and read other content, such as a beacon frame, to obtain the capability information, thereby reducing power consumption of the electronic device.

[0827] After receiving the first information, the electronic device uses the primary transceiver to establish a connection or association with the network and then communicate. The primary transceiver uses a communication protocol in related technologies, such as 802.11b and 802.11n, so that the electronic device can communicate with a network device (such as an AP) in related technologies.

[0828] To sum up, the method provided in this embodiment receives the first information through the first receiver when the first receiver is in an awake state. The first information is used for communication between the electronic device and the wireless network, so that the main transceiver of the electronic device does not need to read the first information from the beacon frame after waking up, which can help the electronic device quickly establish a connection with the wireless network.

[0829] The method provided in this embodiment further includes receiving a second energy-saving signal through the first receiver after the first receiver wakes up, demodulating the second energy-saving signal, and transmitting the corresponding content to the main transceiver. Because the operating energy consumption of the first receiver is less than that of the main transceiver, the power consumption of the electronic device is reduced.

[0830] The method provided in this embodiment also monitors the second energy-saving signal based on the DRX cycle. The energy consumption of using the main transceiver based on the DRX mechanism is lower than that of using the first receiver, and the first receiver does not need to be used, so that the first receiver and the main transceiver are decoupled, thereby adapting to different application scenarios.

[0831] Since the working energy consumption of the first receiver is less than that of the main transceiver, the first receiver receives information communicated between the first receiver and the wireless network, which can reduce the power consumption of the electronic device compared to using the main transceiver to receive the above information.

[0832] In some embodiments, the first information includes information for communication between the first receiver and a wireless network.

[0833] In some embodiments, the first information includes at least one of the following:

[0834] Configuration information for receiving downlink data;

[0835] Configuration information for receiving downlink control signaling;

[0836] Used to receive configuration information broadcast by the system;

[0837] Synchronization information for synchronization;

[0838] Configuration information for receiving a first energy-saving signal;

[0839] Configuration information for receiving a second energy-saving signal;

[0840] Wireless network capability information.

[0841] The configuration information for receiving downlink data includes at least one of the following information: a time domain position for receiving downlink data, a frequency position for receiving downlink data, a period for receiving downlink data, etc.;

[0842] The configuration information for receiving downlink control signaling includes: at least one of: a time domain position for receiving downlink control signaling, a frequency position for receiving downlink control signaling, a control resource set for monitoring downlink control signaling, a search space set for monitoring downlink control signaling, and an RNTI for monitoring downlink control signaling;

[0843] The configuration information for receiving the system broadcast includes at least one of the following information: a time domain position of the broadcast frame, a frequency position of the broadcast frame, a broadcast period of the broadcast frame, etc.;

[0844] The synchronization information used for synchronization includes at least one of synchronization information for time domain synchronization and synchronization information for frequency domain synchronization, and helps the first receiver achieve time and frequency synchronization with the wireless network, so that the master transceiver does not need to perform time and frequency synchronization after waking up;

[0845] The configuration information for receiving the first energy-saving signal includes at least one of the time domain location for receiving the first energy-saving signal, the frequency location for receiving the first energy-saving signal, etc. The first energy-saving signal is a signal for instructing whether to wake up the first receiver.

[0846] The configuration information for receiving the second energy-saving signal includes at least one of information such as a time domain position for receiving the second energy-saving signal and a frequency position for receiving the second energy-saving signal;

[0847] The capability information of the wireless network includes at least one of the bit rate supported by the wireless network, the MCS supported by the wireless network, and other information. This information is generally carried in the beacon frame, so the main transceiver does not need to read the beacon frame after waking up, thereby reducing the power consumption of the electronic device.

[0848] It should be noted that the above examples of information do not limit the first information. The above first information has different names or definitions in different wireless networks. For example, cellular networks use system information broadcast configuration information, while WiFi networks use beacon frames to broadcast configuration information. Such examples will not be repeated here.

[0849] In some embodiments, the first receiver communicates with the wireless network based on the content carried by the first information.

[0850] Exemplarily, when the first information includes configuration information for receiving downlink data, the first receiver receives the downlink data based on information such as a time domain position for receiving the downlink data and a frequency position for receiving the downlink data;

[0851] In a case where the first information includes configuration information for receiving downlink control signaling, the downlink control signaling is used to indicate relevant information for receiving downlink data, the first receiver monitors the downlink control signaling based on a time domain location and a frequency location for receiving the downlink control signaling, and receives the downlink data according to relevant information for receiving the downlink data indicated by the downlink control signaling, thereby communicating with the wireless network;

[0852] In a case where the first information includes configuration information for receiving the system broadcast, the first receiver receives the system broadcast of the wireless network based on information such as a time domain position of the broadcast frame and a frequency position of the broadcast frame;

[0853] In a case where the first information includes synchronization information for synchronization, the first receiver acquires time and frequency synchronization with the wireless network based on the synchronization information for time domain synchronization and / or the synchronization information for frequency domain synchronization;

[0854] In a case where the first information includes configuration information for receiving the first energy-saving signal, the first receiver monitors or receives the first energy-saving signal based on information such as a time domain location for receiving the first energy-saving signal and a frequency location for receiving the first energy-saving signal;

[0855] In a case where the first information includes configuration information for receiving the second energy-saving signal, the first receiver monitors or receives the second energy-saving signal based on information such as a time domain location for receiving the second energy-saving signal and a frequency location for receiving the second energy-saving signal;

[0856] When the first information includes capability information of the wireless network, the first receiver communicates with the wireless network based on information such as the bit rate and MCS supported by the wireless network, for example, at a bit rate of 8 kilobits per second.

[0857] In some embodiments, taking the wireless network as a WiFi network as an example, the first information includes at least one of the following information:

[0858] Network timestamp information when network devices communicate with the master transceiver;

[0859] Frequency location information of the communication channel used by the primary transceiver for communication;

[0860] The time domain location information of the beacon frame;

[0861] Wireless network capability information;

[0862] Synchronization information for synchronization.

[0863] In the case where the first information includes network timestamp information when the network device communicates with the primary transceiver, the electronic device obtains the timestamp information in advance through the first receiver, so that the primary transceiver can obtain the network communication time without reading the beacon frame after waking up. The primary transceiver can be equivalent to a primary transceiver or a primary air interface communication unit;

[0864] When the first information includes frequency position information of a communication channel used by the primary transceiver for communication, the electronic device adjusts the working channel to the frequency position to avoid waking up the primary transceiver and then scanning the frequency of the primary transceiver to obtain the frequency position of the working channel;

[0865] In the case where the first information includes the time domain position information of the beacon frame, the electronic device receives the beacon frame based on the time domain position. For example, at the time domain position of the signal transmission of a non-beacon frame, the electronic device turns off the main transceiver; at the time domain position of the beacon frame transmission, the electronic device turns on the main transceiver, thereby reducing power consumption. At the same time, considering the clock deviation of the electronic device, the main transceiver can be turned on at the first time domain position. The first time domain position is the time domain position of a time margin before the time domain position of the beacon frame transmission. The time margin can be adjusted according to actual conditions.

[0866] In the case where the first information includes capability information of the wireless network, since the capability information of the wireless network is generally carried in a beacon frame, it is possible to avoid the main transceiver from reading the beacon frame after waking up, thereby reducing power consumption of the electronic device;

[0867] In the case that the first information includes synchronization information for synchronization, the first receiver obtains time and frequency synchronization with the wireless network, so that the main transceiver does not need to perform time and frequency synchronization after waking up.

[0868] In some embodiments, the first information includes downlink data, such as data with a data volume lower than a first threshold, or data with a transmission delay requirement lower than a first delay. The first threshold and the first delay are preset values ​​or value ranges.

[0869] In some embodiments, the first information is received by the first receiver. The first receiver receives data with a data volume lower than a first threshold, or data with a transmission delay requirement lower than a first delay, without using a main transceiver for reception, thereby further reducing power consumption of the electronic device.

[0870] To sum up, the method provided in this embodiment receives the first information through the first receiver when the first receiver is in an awake state. The first information is used for communication between the electronic device and the wireless network, and communication with the wireless network is performed through the first receiver without using a main transceiver, thereby saving power of the electronic device.

[0871] In the above embodiments, step 1110 and step 1120 in the embodiment corresponding to Figure 11 can be implemented in combination with the embodiment corresponding to Figure 19 or the embodiment corresponding to Figure 20, for example, step 1110 and step 1120 are performed after step 1930, or step 1110 and step 1120 can be performed after step 1920.

[0872] The embodiment corresponding to FIG. 12 may be implemented in combination with the embodiment corresponding to FIG. 19 or the embodiment corresponding to FIG. 20 . For example, step 1210 may be performed after step 1930 , or step 1210 may be performed after step 1920 .

The primary transceiver receives the second energy-saving signal based on the DRX mechanism, thereby reducing power consumption of the electronic device and extending battery life.

[0913] In the above embodiments, steps with the same sequence number can be considered to be the same step. Among them, the embodiment corresponding to Figure 8, the embodiment corresponding to Figure 10, the embodiment corresponding to Figure 11, the embodiment corresponding to Figure 12, the embodiment corresponding to Figure 13, the embodiment corresponding to Figure 14, the embodiment corresponding to Figure 15, the embodiment corresponding to Figure 16, the embodiment corresponding to Figure 17, the embodiment corresponding to Figure 18, the embodiment corresponding to Figure 19, the embodiment corresponding to Figure 20, the embodiment corresponding to Figure 21, and the embodiment corresponding to Figure 22 can be implemented separately or in combination, and this application does not limit this.

[0914] Figure 23 shows a block diagram of an electronic device provided by an exemplary embodiment of the present application. The device can be implemented as an electronic device, or as a part of an electronic device, through software or hardware or a combination of both. The device has a first receiver and a main transceiver. The working energy consumption of the first receiver is less than the working energy consumption of the main transceiver. The device includes a first receiving module 2310, a second receiving module 2320, a shutdown module 2330, a third receiving module 2340 and a communication module 2350.

[0915] The first receiving module 2310 is configured to receive a first energy-saving signal, where the first energy-saving signal is used to indicate whether to wake up the first receiver.

[0916] In the initial state, both the first receiver and the primary transceiver are in a non-awakened state. This non-awakened state can also be understood as at least one of an off state, a sleep state, and a DRX monitoring state. The sleep state includes at least one of a light sleep state, a deep sleep state, and an ultra-deep sleep state. The light sleep state consumes more power than the deep sleep state, and the deep sleep state consumes more power than the ultra-deep sleep state.

[0917] The first energy-saving signal is used to indicate whether to wake up the first receiver. As an example, the first receiver is a WUR.

[0918] In one possible design of this embodiment, waking up the first receiver can also be equivalently understood as: monitoring the transmission of downlink data or data frames via the first receiver; or equivalently understood as: monitoring the control channel used to schedule uplink data or downlink data or data frames via the first receiver. The above three expressions have the same meaning in the embodiments of this application.

[0919] In one possible design of this embodiment, not waking up the first receiver can also be equivalently understood as keeping the first receiver in an off state; can also be equivalently understood as keeping the first receiver in a sleep state; can also be equivalently understood as keeping the first receiver in a DRX monitoring state. The above four expressions have the same meaning in the embodiments of this application.

[0920] In one possible design of this embodiment, the first energy-saving signal is used to instruct the first receiver to wake up, which can also be equivalently understood as: the first energy-saving signal is used to instruct the first receiver to monitor the transmission of downlink data or data frames; it can also be equivalently understood as: the first energy-saving signal is used to instruct the first receiver to monitor the control channel used for scheduling uplink data or downlink data or data frames. The above three expressions have the same meaning in the embodiments of the present application.

[0921] In one possible design of this embodiment, the first energy-saving signal is used to instruct not to wake up the first receiver. This can also be equivalently understood as: the first energy-saving signal is used to instruct to keep the first receiver in a powered-off state; this can also be equivalently understood as: the first energy-saving signal is used to instruct to keep the first receiver in a sleeping state; this can also be equivalently understood as: the first energy-saving signal is used to instruct to keep the first receiver in a DRX monitoring state. The above four expressions have the same meaning in the embodiments of this application.

[0922] In a possible design of this embodiment, the electronic device is an active device, which refers to a device that has its own power supply and can actively generate and transmit signals, such as a mobile phone, a computer, a smart watch, a smart bracelet, etc.

[0923] In one possible design of this embodiment, the electronic device is a passive device. A passive device refers to a device that does not require a power supply or can operate by receiving energy from other devices. It can be called a zero-power device, a low-power device, etc. The zero-power device can be implemented as at least one of a zero-power device and a zero-power terminal, or as a part of at least one of a zero-power device and a zero-power terminal. The low-power device can be implemented as at least one of a low-power device and a low-power terminal, or as a part of at least one of a low-power device and a low-power terminal.

[0924] In a possible design of this embodiment, the electronic device obtains energy from the environment and can be called an ambient energy Internet of Things device.

[0925] In one possible design of this embodiment, the electronic device is deployed at a fixed location and may be referred to as a zero-power device, a low-power device, or the like. The zero-power device may be implemented as a zero-power site, or as part of a zero-power site. The low-power device may be implemented as a low-power site, or as part of a low-power site.

[0926] In a possible design of this embodiment, the first receiving module 2310 is configured to receive a first energy-saving signal through a first receiver.

[0927] In a possible design of this embodiment, the first energy-saving signal for instructing wake-up and the first energy-saving signal for instructing not to wake up have at least one of the following differences:

[0928] Different waveforms;

[0929] Different modulation methods;

[0930] Sequence lengths vary;

[0931] Different sequences;

[0932] Different frequencies used;

[0933] Different frequency ranges used;

[0934] The values ​​of the information bits carried are different.

[0935] For example, the first energy-saving signal has a first sequence or a second sequence, the first sequence being used to indicate waking up the first receiver, and the second sequence being used to indicate not waking up the first receiver. For example, the first sequence is ZC sequence (Zadoff-Chu sequence) 1, which is used to indicate waking up the first receiver, and the second sequence is ZC sequence 2, which is used to indicate not waking up the first receiver; this is not limited in the embodiments of the present application.

[0936] For another example, the first energy-saving signal has a first sequence length or a second sequence length, the first sequence length being used to indicate waking up the first receiver, and the second sequence length being used to indicate not waking up the first receiver. For example, the first sequence length is 16 bits, which is used to indicate waking up the first receiver, and the second sequence length is 8 bits, which is used to indicate not waking up the first receiver; or the first sequence length is 8 bits, which is used to indicate waking up the first receiver, and the second sequence length is 16 bits, which is used to indicate not waking up the first receiver; this embodiment of the present application is not limited to this.

[0937] In a possible design of this embodiment, the first energy-saving signal is a wake-up signal. The network device sends a dedicated wake-up signal to the electronic device, where the dedicated wake-up signal is a signal different from the energy-supply signal.

[0938] In a possible design of this embodiment, the first energy-saving signal is a power supply signal.

[0939] In a possible design of this embodiment, the first energy-saving signal is sent by a network device or a power supply node.

[0940] Since the network device cannot wake up the electronic device by sending signals to the WUR (first receiver) and the main transceiver when both are in the off state, the WUR can be woken up by sending a power supply signal.

[0941] In a possible design of this embodiment, the first energy-saving signal for indicating not to wake up has a first waveform. For example, the first energy-saving signal is a single-frequency sine wave, and no information is modulated on the single-frequency sine wave.

[0942] In one possible design of this embodiment, the first energy-saving signal for indicating wake-up is a sequence modulated using a first modulation method. For example, the sequence using OOK modulation is 111000 or 101010, where 1 represents a high level of OOK and 0 represents a low level of OOK.

[0943] The modulation mode of the first energy-saving signal may also be FSK, PSK, etc., and the sequence length and sequence may also be other values, which are not limited in the embodiment of the present application.

[0944] In a possible design of this embodiment, the frequency of sending the first energy-saving signal is changed to indicate whether to wake up the WUR.

[0945] For example, the first energy-saving signal is sent at a first frequency point or a first frequency range, and the first frequency point or the first frequency range is used to indicate that the WUR is being woken up.

[0946] For another example, the first energy-saving signal is sent at the second frequency point or within the second frequency range, and the indication sent at the second frequency point or within the second frequency range is not to wake up the WUR.

[0947] The first frequency point and the second frequency point may be located in the same frequency band or in different frequency bands. The first frequency range and the second frequency range may be located in the same frequency band or in different frequency bands.

[0948] The electronic device measures the energy of received signals at two frequency points or two frequency ranges through a peripheral circuit, thereby determining whether the first energy-saving signal is sent at the first frequency point or the second frequency point, or determining whether the first energy-saving signal is sent within the first frequency range or the second frequency range.

[0949] In a possible design of this embodiment, the electronic device further includes a second receiver; and the first receiving module 2310 is configured to receive the first energy-saving signal through the second receiver.

[0950] The second receiver consumes less energy than the first receiver. For example, the second receiver 730 is an RF-based receiver (RF envelope detection receiver), while the first receiver 710 is an intermediate frequency (IF)-based receiver. Therefore, the power consumption of the second receiver 730 is a few microwatts, for example, 5 microwatts, while the power consumption of the first receiver 710 is hundreds of microwatts, for example, 100 microwatts. Therefore, the power consumption of the second receiver 730 is less than that of the first receiver 710.

[0951] In a possible design of this embodiment, the second receiver and the first receiver are on the same chip or on different chips and are connected via electronic leads.

[0952] In a possible design of this embodiment, the first receiving module 2310 can be implemented by a first receiver or a second receiver.

[0953] In a possible design of this embodiment, the electronic device further includes a first circuit; and a first receiving module 2310, configured to receive a first energy-saving signal through the first circuit.

[0954] In a possible design of this embodiment, the first circuit includes a wireless energy harvesting circuit of the electronic device, or a peripheral circuit of the first receiver.

[0955] The wireless energy harvesting circuit is used for performing wireless energy harvesting. When the first receiver and the main transceiver are both turned off, the wireless energy harvesting circuit remains in operation and continues to perform wireless energy harvesting.

[0956] The electronic device measures the received signal energy at two frequency points or two frequency ranges through a first circuit, thereby determining whether the first energy-saving signal is sent at the first frequency point or the second frequency point, or determining whether the first energy-saving signal is sent within the first frequency range or the second frequency range.

[0957] In a possible design of this embodiment, the first receiver uses first receiver parameters, where the first receiver parameters include a first receiver type and / or a first receiving bandwidth.

[0958] The receiver type indicates the type of receiver architecture used by the electronic device, such as an RF-based receiver or an intermediate frequency (zero intermediate frequency)-based receiver; the receiving bandwidth indicates the bandwidth used to receive signals.

[0959] In one possible design of this embodiment, the first receiver type is an RF-based receiver type. Using the first receiver type (RF envelope detection receiver type) directly detects the RF signal, eliminating the need for frequency conversion or conversion of the RF signal to a baseband signal. This reduces power consumption of the first receiver.

[0960] Since this receiver type can only receive the first energy-saving signal within a specified frequency range based on the implemented RF filter or matching network parameters, the first energy-saving signal can be received on the first frequency band or the first channel within the first frequency band.

[0961] In a possible design of this embodiment, the first receiving module 2310 is configured to receive a first energy-saving signal within a first frequency band.

[0962] The receiving bandwidth of the first receiver is equal to the bandwidth of the first frequency band, and the first receiver receives the first energy-saving signal within a bandwidth range not exceeding the first frequency band, for example, the first energy-saving signal is received at 920 MHz to 925 MHz.

[0963] In a possible design of this embodiment, the first receiving module 2310 is used to receive a first energy-saving signal on a first channel in a first frequency band.

[0964] When the first frequency band includes multiple channels, the first energy-saving signal is received on one of the channels (the first channel), and the receiving bandwidth of the first receiver is equal to the bandwidth of the first channel. For example, 20 channels with a bandwidth of 250 kHz are allocated within the 920 MHz to 925 MHz frequency band, and the first energy-saving signal is received on the first channel.

[0965] For another example, when operating at 2.4 GHz, the frequency band is 2400 MHz to 2485 MHz, which can be divided into multiple channels, such as a channel from 2400 MHz to 2420 MHz, a channel from 2420 MHz to 2440 MHz, a channel from 2440 MHz to 2460 MHz, etc. Therefore, the first energy-saving signal can be received on a first channel within the frequency band, such as a channel from 2400 MHz to 2420 MHz.

[0966] In a possible design of this embodiment, the first channel is any channel in the first frequency band; or,

[0967] The first channel is a designated channel in the first frequency band; or,

[0968] The first channel is the centralmost channel in the first frequency band; or

[0969] The first channel is one of the two central channels in the first frequency band.

[0970] When the number of channels included in the first frequency band is an odd number, the first channel is the most central channel in the first frequency band; when the number of channels included in the first frequency band is an even number, the first channel is one of the two most central channels in the first frequency band.

[0971] Exemplarily, when the first frequency band includes five channels, the first channel is the most central channel (the third channel); or, when the first frequency band includes four channels, the first channel is one of the two most central channels (the second channel or the third channel).

[0972] In a possible design of this embodiment, the second receiving module 2320 is used to receive a second energy-saving signal, and the second energy-saving signal is used to indicate whether to wake up the main transceiver.

[0973] In a possible design of this embodiment, waking up the main transceiver can also be equivalently understood as waking up the main transceiver; or can also be equivalently understood as waking up the main air interface communication unit. The above three expressions have the same meaning in the embodiment of this application.

[0974] In one possible design of this embodiment, waking up the master transceiver can also be equivalently understood as: monitoring the transmission of downlink data or data frames via the master transceiver; or equivalently understood as: monitoring the control channel used to schedule uplink data or downlink data or data frames via the master transceiver. The above three expressions have the same meaning in the embodiments of this application.

[0975] In one possible design of this embodiment, not waking up the primary transceiver can also be equivalently understood as: keeping the primary transceiver in a turned-off state; or can also be equivalently understood as: keeping the primary transceiver in a DRX monitoring state. The above three expressions have the same meaning in the embodiments of this application.

[0976] In a possible design of this embodiment, the second energy-saving signal for instructing wake-up and the second energy-saving signal for instructing not to wake up have at least one of the following differences:

[0977] Different waveforms;

[0978] Different modulation methods;

[0979] Sequence lengths vary;

[0980] Different sequences;

[0981] Different frequencies used;

[0982] Different frequency ranges used;

[0983] The values ​​of the information bits carried are different.

[0984] For example, the first energy-saving signal has a first sequence or a second sequence, the first sequence being used to indicate waking up the first receiver, and the second sequence being used to indicate not waking up the first receiver. For example, the first sequence is ZC sequence (Zadoff-Chu sequence) 1, which is used to indicate waking up the first receiver, and the second sequence is ZC sequence 2, which is used to indicate not waking up the first receiver; this is not limited in the embodiments of the present application.

[0985] For another example, the first energy-saving signal has a first sequence length or a second sequence length, the first sequence length being used to indicate waking up the first receiver, and the second sequence length being used to indicate not waking up the first receiver. For example, the first sequence length is 16 bits, which is used to indicate waking up the first receiver, and the second sequence length is 8 bits, which is used to indicate not waking up the first receiver; or the first sequence length is 8 bits, which is used to indicate waking up the first receiver, and the second sequence length is 16 bits, which is used to indicate not waking up the first receiver; this embodiment of the present application is not limited to this.

[0986] In a possible design of this embodiment, the second receiving module 2320 is used to receive the second energy-saving signal through the first receiver after the first receiver is awakened.

[0987] When the first receiver is awakened, it receives the second energy-saving signal, demodulates the second energy-saving signal, and transmits corresponding content to the main transceiver to instruct whether to wake up the main transceiver.

[0988] In one possible design of this embodiment, "after the first receiver wakes up" can also be equivalently understood as: after the first receiver enters a state of monitoring the transmission of downlink data or data frames; it can also be equivalently understood as: after the first receiver enters a state of monitoring a control channel for scheduling uplink data or downlink data or data frames. The above three expressions have the same meaning in the embodiments of this application.

[0989] In a possible design of this embodiment, the first receiver monitors the second energy-saving signal based on the DRX cycle; if the second energy-saving signal associated with the first DRX cycle is monitored, the main transceiver is kept in an awake state or in a non-awakened state during the activation time period in the first DRX cycle according to the indication of the second energy-saving signal associated with the first DRX cycle.

[0990] The second energy-saving signal is sent in either of the following two ways:

[0991] (1) The second energy-saving signal is always sent, and each second energy-saving signal carries a wake-up indication or a non-wake-up indication.

[0992] The first receiver monitors the second energy-saving signal based on the DRX cycle; if the second energy-saving signal associated with the first DRX cycle is monitored, the main transceiver is controlled to be in an awake state during the activation time period of the first DRX cycle according to the wake-up indication carried by the second energy-saving signal; or the main transceiver is kept in a non-awakening state during the activation time period of the first DRX cycle according to the non-wake-up indication carried by the second energy-saving signal.

[0993] (2) The second energy-saving signal is sent on demand, indicating wake-up when sent and not indicating not wake-up when not sent.

[0994] The first receiver monitors the second energy-saving signal based on the DRX cycle; if the second energy-saving signal associated with the first DRX cycle is monitored, the main transceiver is kept in an awake state during the activation time period of the first DRX cycle according to the instruction of the second energy-saving signal associated with the first DRX cycle; if the second energy-saving signal associated with the first DRX cycle is not monitored, the main transceiver is kept in a non-awakened state during the activation time period of the first DRX cycle.

[0995] In a possible design of this embodiment, the second energy-saving signal associated with the first DRX cycle can be sent before the activation time period of the first DRX cycle, or can be sent at an initial position in the activation time period of the first DRX cycle.

[0996] In a possible design of this embodiment, the second receiving module 2320 is configured to receive the second energy-saving signal through the main transceiver.

[0997] Wherein, the first receiver and the main transceiver are both in a non-awakening state.

[0998] In a possible design of this embodiment, the main transceiver monitors the second energy-saving signal based on the DRX cycle; if the second energy-saving signal associated with the first DRX cycle is monitored, the main transceiver is kept in an awake state or in a non-awakened state during the activation time period in the first DRX cycle according to the indication of the second energy-saving signal associated with the first DRX cycle.

[0999] The second energy-saving signal is sent in either of the following two ways:

[1000] (1) The second energy-saving signal is always sent, and each second energy-saving signal carries a wake-up indication or a non-wake-up indication.

[1001] The main transceiver monitors the second energy-saving signal based on the DRX cycle; if the second energy-saving signal associated with the first DRX cycle is monitored, the main transceiver is controlled to be in an awake state during the activation time period in the first DRX cycle according to the wake-up indication carried by the second energy-saving signal; or the main transceiver is kept in a non-awakening state during the activation time period in the first DRX cycle according to the non-wake-up indication carried by the second energy-saving signal.

[1002] (2) The second energy-saving signal is sent on demand, indicating wake-up when sent and not indicating not wake-up when not sent.

[1003] The main transceiver monitors the second energy-saving signal based on the DRX cycle; if the second energy-saving signal associated with the first DRX cycle is monitored, the main transceiver is kept in an awake state during the activation time period of the first DRX cycle according to the instruction of the second energy-saving signal associated with the first DRX cycle; if the second energy-saving signal associated with the first DRX cycle is not monitored, the main transceiver is kept in a non-awakened state during the activation time period of the first DRX cycle.

[1004] In a possible design of this embodiment, the second energy-saving signal associated with the first DRX cycle can be sent before the activation time period of the first DRX cycle, or can be sent at an initial position in the activation time period of the first DRX cycle.

[1005] In one possible design of this embodiment, maintaining the master transceiver in an awake state during the active time period of the first DRX cycle can also be equivalently understood as: monitoring the transmission of downlink data or data frames through the master transceiver during the active time period of the first DRX cycle; can also be equivalently understood as: monitoring the control channel used for scheduling uplink data or downlink data or data frames through the master transceiver during the active time period of the first DRX cycle. The above three expressions have the same meaning in the embodiments of the present application.

[1006] Maintaining the master transceiver in a non-awakened state during the active time period of the first DRX cycle can also be equivalently understood as: during the active time period of the first DRX cycle, the master transceiver does not monitor the transmission of downlink data or data frames; can also be equivalently understood as: during the active time period of the first DRX cycle, the master transceiver does not monitor the control channel used for scheduling uplink data or downlink data or data frames. The above three expressions have the same meaning in the embodiments of the present application.

[1007] A DRX cycle includes "On Duration" and "Opportunity for DRX". During the On Duration (activation time period), the electronic device is in an awake state receiving data, and during the DRX opportunity, the electronic device is in a sleep state not receiving data.

[1008] Exemplarily, the electronic device monitors a second energy-saving signal based on a DRX cycle, and monitors the second energy-saving signal before the activation time period of the first DRX cycle. The second energy-saving signal indicates that the main transceiver is in an awake state. Then, during the activation time period in the first DRX cycle, the main transceiver is kept in an awake state.

[1009] In a possible design of this embodiment, the first energy-saving signal further carries an identifier of the device to be awakened or an identifier of a group of devices to be awakened.

[1010] In a possible design of this embodiment, the second energy-saving signal further carries an identifier of the device to be awakened or an identifier of a group of devices to be awakened.

[1011] The identifier of the device group to be awakened, that is, the device group ID to be awakened, is the ID of the group where the device to be awakened belongs. The group includes at least one device to be awakened.

[1012] Based on the ID of the device to be awakened or the group ID of the device to be awakened carried in the first or second energy-saving signal, determine whether the electronic device needs to be awakened. If the ID of the electronic device is the same as the ID of the device to be awakened, the electronic device is awakened; if the ID of the electronic device is different from the ID of the device to be awakened, the electronic device is not awakened. If the group ID of the electronic device is the same as the group ID of the device to be awakened, the electronic device is awakened; if the group ID of the electronic device is different from the group ID of the device to be awakened, the electronic device is awakened.

[1013] In one possible design of this embodiment, the second energy-saving signal further carries synchronization information, and the synchronization information is used to synchronize the wireless network and the electronic device. Synchronization includes time domain synchronization and / or frequency domain synchronization. The wireless network includes at least one of a WiFi network, a cellular network, and a wireless power supply network.

[1014] In a possible design of this embodiment, the shut-down module 2330 is configured to shut down the main transceiver when a first condition is met.

[1015] Since the main transceiver consumes a lot of energy, when the first condition is met, the main transceiver is turned off.

[1016] For example, the electricity consumption of different users is queried through the Internet of Things electricity meter, and after the query is completed, the main transceiver is turned off.

[1017] In a possible design of this embodiment, the shut-down module 2330 is configured to shut down the first receiver when the second condition is met.

[1018] Among them, the first condition and the second condition are two different conditions.

[1019] Although the operating energy consumption of the first receiver is less than that of the main transceiver, in order to further save power, the first receiver is turned off when the second condition is met.

[1020] For example, the electricity consumption of different users is queried through the IoT electricity meter, and after the query is completed, the main transceiver is turned off. When feedback information such as ACK information sent by the wireless network is received, the first receiver is turned off.

[1021] In a possible design of this embodiment, the shut-down module 2330 is configured to shut down the first receiver and the main transceiver when a third condition is met.

[1022] Among them, the third condition is different from the first condition and the second condition.

[1023] In order to further save power, when the third condition is met, the first receiver and the main transceiver are all turned off.

[1024] Exemplarily, when the IoT storage device receives all the item data stored in the warehouse, the first receiver and the main transceiver are all turned off.

[1025] In a possible design of this embodiment, the shut-down module 2330 can be implemented independently as a shut-down device for a receiver.

[1026] In a possible design of this embodiment, the third receiving module 2340 is configured to receive the first information through the first receiver when the first receiver is in an awake state;

[1027] The first information is used for communication between the electronic device and a wireless network, which includes at least one of a WiFi network, a cellular network, and a wireless power supply network.

[1028] In a possible design of this embodiment, the first information includes: information used for communication between the first receiver and the wireless network.

[1029] In a possible design of this embodiment, the electronic device is an active device, which refers to a device that has its own power supply and can actively generate and transmit signals, such as a mobile phone, a computer, a smart watch, a smart bracelet, etc.

[1030] In one possible design of this embodiment, the electronic device is a passive device. A passive device refers to a device that does not require a power supply or can operate by receiving energy from other devices. It can be called a zero-power device, a low-power device, etc. The zero-power device can be implemented as at least one of a zero-power device and a zero-power terminal, or as a part of at least one of a zero-power device and a zero-power terminal. The low-power device can be implemented as at least one of a low-power device and a low-power terminal, or as a part of at least one of a low-power device and a low-power terminal.

[1031] In a possible design of this embodiment, the electronic device obtains energy from the environment and can be called an ambient energy Internet of Things device.

[1032] In one possible design of this embodiment, the electronic device is deployed at a fixed location and may be referred to as a zero-power device, a low-power device, or the like. The zero-power device may be implemented as a zero-power site, or as part of a zero-power site. The low-power device may be implemented as a low-power site, or as part of a low-power site.

[1033] In a possible design of this embodiment, when the first receiver is in an awake state, the network device or the power supply node 630 in the embodiment of Figure 6 sends first information to the first receiver. The first information can be called auxiliary information to help the electronic device quickly establish a connection with the wireless network and complete communication after waking up the main transceiver.

[1034] In a possible design of this embodiment, the first information includes: information used for communication between the primary transceiver and the wireless network. This can also be equivalently understood as the first information including: information used for communication between the primary transceiver (or primary air interface communication unit) and the wireless network.

[1035] In a possible design of this embodiment, the first information includes but is not limited to at least one of the following information:

[1036] Configuration information for receiving downlink data;

[1037] Configuration information for receiving downlink control signaling;

[1038] Used to receive configuration information broadcast by the system;

[1039] Configuration information for sending uplink data;

[1040] Configuration information used to send uplink control signaling;

[1041] Synchronization information for synchronization;

[1042] Configuration information for receiving a second energy-saving signal;

[1043] Wireless network capability information.

[1044] The configuration information for receiving downlink data includes at least one of the following information: a time domain position for receiving downlink data, a frequency position for receiving downlink data, a period for receiving downlink data, etc.;

[1045] The configuration information for receiving downlink control signaling includes: at least one of: a time domain position for receiving downlink control signaling, a frequency position for receiving downlink control signaling, a control resource set for monitoring downlink control signaling, a search space set for monitoring downlink control signaling, and an RNTI for monitoring downlink control signaling;

[1046] The configuration information for receiving the system broadcast includes at least one of the following information: a time domain position of the broadcast frame, a frequency position of the broadcast frame, a broadcast period of the broadcast frame, etc.;

[1047] The configuration information for sending uplink data includes at least one of the following information: a time domain position for sending uplink data, a frequency position for sending uplink data, a period for sending uplink data, etc.;

[1048] The configuration information for sending uplink control signaling includes: at least one of information such as a time domain position for sending uplink control signaling and a frequency position for sending uplink control signaling;

[1049] The synchronization information used for synchronization includes at least one of synchronization information for time domain synchronization and synchronization information for frequency domain synchronization, and helps the first receiver achieve time and frequency synchronization with the wireless network;

[1050] The configuration information for receiving the second energy-saving signal includes at least one of information such as a time domain position for receiving the second energy-saving signal and a frequency position for receiving the second energy-saving signal;

[1051] The capability information of the wireless network includes at least one of the following information: the bit rate supported by the wireless network, the MCS supported by the wireless network, etc., and such information is generally carried in a beacon frame.

[1052] It should be noted that the above examples of information do not limit the first information. The above first information has different names or definitions in different wireless networks. For example, cellular networks use system information broadcast configuration information, while WiFi networks use beacon frames to broadcast configuration information. Such examples will not be repeated here.

[1053] In a possible design of this embodiment, the frequency position may be in a channel, bandwidth, or carrier format, etc. For example, downlink data is received on a first channel.

[1054] In a possible design of this embodiment, the relevant information of the frequency position can enable the electronic device to obtain the frequency position when the main transceiver communicates with the wireless network through the first receiver, avoiding the need to obtain the frequency position through frequency scanning after the main transceiver wakes up, thereby reducing power consumption.

[1055] In a possible design of this embodiment, the first information is sent via a data frame; or, the first information is sent via a beacon frame.

[1056] In a possible design of this embodiment, the network device first sends the first information and then sends the second energy-saving signal.

[1057] In a possible design of this embodiment, the first information is carried in the second energy-saving signal.

[1058] After waking up the first receiver, the network device sends a second energy-saving signal. By receiving the second energy-saving signal, the electronic device can simultaneously obtain at least one of the first information, information on whether to wake up the main transceiver, and synchronization information for synchronization.

[1059] In a possible design of this embodiment, the communication module 2350 is configured to communicate with the wireless network based on the first information when the main transceiver is in an awake state.

[1060] When the main transceiver is in an awake state, the electronic device obtains the configuration of the wireless network based on the content carried by the first information.

[1061] Exemplarily, when the first information includes configuration information for receiving downlink data, the primary transceiver receives the downlink data based on information such as the time domain location and frequency location of the downlink data. Before receiving the downlink data, the primary transceiver may be kept in a non-awakened state as much as possible, thereby further saving power.

[1062] In a case where the first information includes configuration information for receiving downlink control signaling, the downlink control signaling is used to indicate relevant information for receiving downlink data. The master transceiver monitors the downlink control signaling based on the time domain location and frequency location of receiving the downlink control signaling, and receives downlink data according to the relevant information for receiving the downlink data indicated by the downlink control signaling, thereby communicating with the wireless network. By receiving the configuration information in advance, the master transceiver can remain in the non-awakened state for a longer period of time, thereby reducing power consumption of the electronic device.

[1063] When the first information includes configuration information for receiving a system broadcast, the primary transceiver receives the system broadcast of the wireless network based on information such as the time domain position and frequency position of the broadcast frame. By receiving the configuration information of the system broadcast in advance, the primary transceiver can remain in a non-awakened state during the stages of receiving the system broadcast and obtaining the configuration information in the system broadcast, thereby saving power.

[1064] When the first information includes configuration information for sending uplink data, the master transceiver sends the uplink data based on information such as the time domain location and frequency location of the uplink data. Before receiving the uplink data, the master transceiver can be kept in a non-awakened state as much as possible, thereby saving power.

[1065] In the case where the first information includes configuration information for sending uplink control signaling, the uplink control signaling is used to provide feedback on whether downlink data has been received, and the master transceiver monitors the uplink control signaling based on information such as the time domain location and frequency location of the uplink control signaling. By receiving the configuration information in advance, the master transceiver can remain in a non-awakened state for a longer period of time, thereby reducing power consumption of the electronic device;

[1066] In a case where the first information includes synchronization information for synchronization, the electronic device enables the master transceiver to obtain time and frequency synchronization with the wireless network based on the synchronization information for time domain synchronization and / or the synchronization information for frequency domain synchronization, thereby eliminating the need for the master transceiver to wake up and then perform time and frequency synchronization;

[1067] When the first information includes configuration information for receiving the second energy-saving signal, the master transceiver monitors or receives the second energy-saving signal based on information such as the time domain location and frequency location of receiving the second energy-saving signal. By receiving the configuration information in advance, the master transceiver remains in a non-awakened state for a longer period of time, thereby reducing power consumption of the electronic device.

[1068] When the first information includes wireless network capability information, the primary transceiver communicates with the wireless network based on information such as the bit rate and MCS supported by the wireless network, for example, communicating with the wireless network at a bit rate of 128 kilobits per second. This eliminates the need for the primary transceiver to wake up and read other content, such as a beacon frame, to obtain the capability information, thereby reducing power consumption of the electronic device.

[1069] After receiving the first information, the electronic device uses the main transceiver to establish a connection or association with the network and then communicate. The main transceiver uses a communication protocol in the related art, such as 802.11b, 802.11n, so that the electronic device can communicate with a network device (such as an AP) in the related art.

[1070] Since the working energy consumption of the first receiver is less than that of the main transceiver, the first receiver receives information communicated between the first receiver and the wireless network, which can reduce the power consumption of the electronic device compared to using the main transceiver to receive the above information.

[1071] In one possible design of this embodiment, the first information includes at least one of the following:

[1072] Configuration information for receiving downlink data;

[1073] Configuration information for receiving downlink control signaling;

[1074] Used to receive configuration information broadcast by the system;

[1075] Synchronization information for synchronization;

[1076] Configuration information for receiving a first energy-saving signal;

[1077] Configuration information for receiving a second energy-saving signal;

[1078] Wireless network capability information.

[1079] The configuration information for receiving downlink data includes at least one of the following information: a time domain position for receiving downlink data, a frequency position for receiving downlink data, a period for receiving downlink data, etc.;

[1080] The configuration information for receiving downlink control signaling includes: at least one of: a time domain position for receiving downlink control signaling, a frequency position for receiving downlink control signaling, a control resource set for monitoring downlink control signaling, a search space set for monitoring downlink control signaling, and an RNTI for monitoring downlink control signaling;

[1081] The configuration information for receiving the system broadcast includes at least one of the following information: a time domain position of the broadcast frame, a frequency position of the broadcast frame, a broadcast period of the broadcast frame, etc.;

[1082] The synchronization information used for synchronization includes at least one of synchronization information for time domain synchronization and synchronization information for frequency domain synchronization, and helps the first receiver achieve time and frequency synchronization with the wireless network, so that the master transceiver does not need to perform time and frequency synchronization after waking up;

[1083] The configuration information for receiving the first energy-saving signal includes at least one of information such as a time domain position for receiving the first energy-saving signal and a frequency position for receiving the first energy-saving signal;

[1084] The configuration information for receiving the second energy-saving signal includes at least one of information such as a time domain position for receiving the second energy-saving signal and a frequency position for receiving the second energy-saving signal;

[1085] The capability information of the wireless network includes at least one of the bit rate supported by the wireless network, the MCS supported by the wireless network, and other information. This information is generally carried in the beacon frame, so the main transceiver does not need to read the beacon frame after waking up, thereby reducing the power consumption of the electronic device.

[1086] It should be noted that the above examples of information do not limit the first information. The above first information has different names or definitions in different wireless networks. For example, cellular networks use system information broadcast configuration information, while WiFi networks use beacon frames to broadcast configuration information. Such examples will not be repeated here.

[1087] In a possible design of this embodiment, the first receiver communicates with the wireless network based on content carried by the first information.

[1088] Exemplarily, when the first information includes configuration information for receiving downlink data, the first receiver receives the downlink data based on information such as a time domain position for receiving the downlink data and a frequency position for receiving the downlink data;

[1089] In a case where the first information includes configuration information for receiving downlink control signaling, the downlink control signaling is used to indicate relevant information for receiving downlink data, the first receiver monitors the downlink control signaling based on a time domain location and a frequency location for receiving the downlink control signaling, and receives the downlink data according to relevant information for receiving the downlink data indicated by the downlink control signaling, thereby communicating with the wireless network;

[1090] In a case where the first information includes configuration information for receiving the system broadcast, the first receiver receives the system broadcast of the wireless network based on information such as a time domain position of the broadcast frame and a frequency position of the broadcast frame;

[1091] In a case where the first information includes synchronization information for synchronization, the first receiver acquires time and frequency synchronization with the wireless network based on the synchronization information for time domain synchronization and / or the synchronization information for frequency domain synchronization;

[1092] In a case where the first information includes configuration information for receiving the first energy-saving signal, the first receiver monitors or receives the first energy-saving signal based on information such as a time domain location for receiving the first energy-saving signal and a frequency location for receiving the first energy-saving signal;

[1093] In a case where the first information includes configuration information for receiving the second energy-saving signal, the first receiver monitors or receives the second energy-saving signal based on information such as a time domain location for receiving the second energy-saving signal and a frequency location for receiving the second energy-saving signal;

[1094] When the first information includes capability information of the wireless network, the first receiver communicates with the wireless network based on information such as the bit rate and MCS supported by the wireless network, for example, at a bit rate of 8 kilobits per second.

[1095] In a possible design of this embodiment, taking the wireless network as a WiFi network as an example, the first information includes at least one of the following information:

[1096] Network timestamp information when the network device communicates with the host transceiver;

[1097] Frequency location information of the communication channel used by the primary transceiver for communication;

[1098] The time domain location information of the beacon frame;

[1099] Wireless network capability information;

[1100] Synchronization information for synchronization.

[1101] In the case where the first information includes network timestamp information when the network device communicates with the primary transceiver, the electronic device obtains the timestamp information in advance through the first receiver, so that the primary transceiver can obtain the network communication time without reading the beacon frame after waking up. The primary transceiver can be equivalent to a primary transceiver or a primary air interface communication unit;

[1102] When the first information includes frequency position information of a communication channel used by the primary transceiver for communication, the electronic device adjusts the working channel to the frequency position to avoid waking up the primary transceiver and then scanning the frequency of the primary transceiver to obtain the frequency position of the working channel;

[1103] In the case where the first information includes the time domain position information of the beacon frame, the electronic device receives the beacon frame based on the time domain position. For example, at the time domain position of the signal transmission of a non-beacon frame, the electronic device turns off the main transceiver; at the time domain position of the beacon frame transmission, the electronic device turns on the main transceiver, thereby reducing power consumption. At the same time, considering the clock deviation of the electronic device, the main transceiver can be turned on at the first time domain position. The first time domain position is the time domain position of a time margin before the time domain position of the beacon frame transmission. The time margin can be adjusted according to actual conditions.

[1104] In the case where the first information includes capability information of the wireless network, since the capability information of the wireless network is generally carried in a beacon frame, it is possible to avoid the main transceiver from reading the beacon frame after waking up, thereby reducing the power consumption of the electronic device;

[1105] In the case that the first information includes synchronization information for synchronization, the first receiver obtains time and frequency synchronization with the wireless network, so that the main transceiver does not need to perform time and frequency synchronization after waking up.

[1106] In one possible design of this embodiment, the first information includes downlink data, such as data having a data volume lower than a first threshold, or data requiring a transmission delay lower than a first delay. The first threshold and the first delay are preset values ​​or value ranges.

[1107] In one possible design of this embodiment, the first information is received by the first receiver. When the first receiver receives data with a data volume lower than a first threshold or data requiring a transmission delay lower than a first delay, the first receiver does not need to use a main transceiver for reception, thereby further reducing power consumption of the electronic device.

[1108] In this embodiment, the first receiving module 2310 can be split into multiple receiving submodules, such as a first receiving submodule, a second receiving submodule, and a third receiving submodule. The first receiving submodule is configured to receive the first energy-saving signal via the second receiver, the second receiving submodule is configured to receive the first energy-saving signal via the first circuit, and the third receiving submodule is configured to receive the first energy-saving signal via the first receiver; or the first receiving submodule is configured to receive the first energy-saving signal via the first circuit, the second receiving submodule is configured to receive the first energy-saving signal via the first receiver, and the third receiving submodule is configured to receive the first energy-saving signal via the second receiver. This embodiment does not limit the functions of the different receiving submodules.

[1109] In this embodiment, the second receiving module 2320 can be split into multiple receiving submodules, such as a first receiving submodule and a second receiving submodule. The first receiving submodule is configured to receive the second energy-saving signal via the first receiver after the first receiver is awakened, and the second receiving submodule is configured to receive the second energy-saving signal via the main transceiver; alternatively, the first receiving submodule is configured to receive the second energy-saving signal via the main transceiver, and the second receiving submodule is configured to receive the second energy-saving signal via the first receiver after the first receiver is awakened. This embodiment does not limit the functions of the different receiving submodules.

[1110] In this embodiment, the shutdown module 2330 can be divided into multiple shutdown modules, such as a first shutdown module, a second shutdown module, and a third shutdown module. The first shutdown module is configured to shut down the main transceiver when a first condition is met, the second shutdown module is configured to shut down the first receiver when a second condition is met, and the third shutdown module is configured to shut down the first receiver and the main transceiver when the third condition is met. Alternatively, the first shutdown module is configured to shut down the first receiver when the second condition is met, the second shutdown module is configured to shut down the first receiver and the main transceiver when the third condition is met, and the main transceiver is shut down when the first condition is met, and the third shutdown module is configured to shut down the main transceiver when the first condition is met. This embodiment does not limit the functions of the different shutdown modules.

[1119] Figure 24 shows a block diagram of a network device provided by an exemplary embodiment of the present application. The device can be implemented as a network device or as a part of a network device through software or hardware or a combination of both. The device includes a first sending module 2410, a second sending module 2420 and a third sending module 2430.

[1120] The first sending module 2410 is configured to send a first energy-saving signal, where the first energy-saving signal is used to indicate whether to wake up the first receiver.

[1121] The electronic device comprises a first receiver and a main transceiver, and the working energy consumption of the first receiver is less than the working energy consumption of the main transceiver.

[1122] In the initial state, both the first receiver and the primary transceiver are in a non-awakened state. This non-awakened state can also be understood as at least one of an off state, a sleep state, and a DRX monitoring state. The sleep state includes at least one of a light sleep state, a deep sleep state, and an ultra-deep sleep state. The light sleep state consumes more power than the deep sleep state, and the deep sleep state consumes more power than the ultra-deep sleep state.

[1123] The first energy-saving signal is used to indicate whether to wake up the first receiver. As an example, the first receiver is a WUR.

[1124] In one possible design of this embodiment, waking up the first receiver can also be equivalently understood as: monitoring the transmission of downlink data or data frames via the first receiver; or equivalently understood as: monitoring the control channel used to schedule uplink data or downlink data or data frames via the first receiver. The above three expressions have the same meaning in the embodiments of this application.

[1125] In one possible design of this embodiment, not waking up the first receiver can also be equivalently understood as keeping the first receiver in an off state; can also be equivalently understood as keeping the first receiver in a sleep state; can also be equivalently understood as keeping the first receiver in a DRX monitoring state. The above four expressions have the same meaning in the embodiments of this application.

[1126] In one possible design of this embodiment, the first energy-saving signal is used to instruct the first receiver to wake up, which can also be equivalently understood as: the first energy-saving signal is used to instruct the first receiver to monitor the transmission of downlink data or data frames; it can also be equivalently understood as: the first energy-saving signal is used to instruct the first receiver to monitor the control channel used for scheduling uplink data or downlink data or data frames. The above three expressions have the same meaning in the embodiments of the present application.

[1127] In one possible design of this embodiment, the first energy-saving signal is used to instruct not to wake up the first receiver. This can also be equivalently understood as: the first energy-saving signal is used to instruct to keep the first receiver in a powered-off state; this can also be equivalently understood as: the first energy-saving signal is used to instruct to keep the first receiver in a sleeping state; this can also be equivalently understood as: the first energy-saving signal is used to instruct to keep the first receiver in a DRX monitoring state. The above four expressions have the same meaning in the embodiments of this application.

[1128] In a possible design of this embodiment, the electronic device is an active device, which refers to a device that has its own power supply and can actively generate and transmit signals, such as a mobile phone, a computer, a smart watch, a smart bracelet, etc.

[1129] In one possible design of this embodiment, the electronic device is a passive device. A passive device refers to a device that does not require a power supply or can operate by receiving energy from other devices. It can be called a zero-power device, a low-power device, etc. The zero-power device can be implemented as at least one of a zero-power device and a zero-power terminal, or as a part of at least one of a zero-power device and a zero-power terminal. The low-power device can be implemented as at least one of a low-power device and a low-power terminal, or as a part of at least one of a low-power device and a low-power terminal.

[1130] In a possible design of this embodiment, the electronic device obtains energy from the environment and can be called an ambient energy Internet of Things device.

[1131] In one possible design of this embodiment, the electronic device is deployed at a fixed location and may be referred to as a zero-power device, a low-power device, or the like. The zero-power device may be implemented as a zero-power site, or as part of a zero-power site. The low-power device may be implemented as a low-power site, or as part of a low-power site.

[1132] In a possible design of this embodiment, the first energy-saving signal is a signal received by the electronic device through a first receiver.

[1133] In a possible design of this embodiment, the first energy-saving signal for instructing wake-up and the first energy-saving signal for instructing not to wake up have at least one of the following differences:

[1134] Different waveforms;

[1135] Different modulation methods;

[1136] Sequence lengths vary;

[1137] Different sequences;

[1138] Different frequencies used;

[1139] Different frequency ranges used;

[1140] The values ​​of the information bits carried are different.

[1141] For example, the first energy-saving signal has a first sequence or a second sequence, the first sequence being used to indicate waking up the first receiver, and the second sequence being used to indicate not waking up the first receiver. For example, the first sequence is ZC sequence (Zadoff-Chu sequence) 1, which is used to indicate waking up the first receiver, and the second sequence is ZC sequence 2, which is used to indicate not waking up the first receiver; this is not limited in the embodiments of the present application.

[1142] For another example, the first energy-saving signal has a first sequence length or a second sequence length, the first sequence length being used to indicate waking up the first receiver, and the second sequence length being used to indicate not waking up the first receiver. For example, the first sequence length is 16 bits, which is used to indicate waking up the first receiver, and the second sequence length is 8 bits, which is used to indicate not waking up the first receiver; or the first sequence length is 8 bits, which is used to indicate waking up the first receiver, and the second sequence length is 16 bits, which is used to indicate not waking up the first receiver; this embodiment of the present application is not limited to this.

[1143] In a possible design of this embodiment, the first energy-saving signal is a wake-up signal. The network device sends a dedicated wake-up signal to the electronic device, where the dedicated wake-up signal is a signal different from the energy-supply signal.

[1144] In a possible design of this embodiment, the first energy-saving signal is a power supply signal.

[1145] In a possible design of this embodiment, the first energy-saving signal is sent by the network device or the energy supply node.

[1146] Since the network device cannot wake up the electronic device by sending signals to the WUR (first receiver) and the main transceiver when both are in the off state, the WUR can be woken up by sending a power supply signal.

[1147] In a possible design of this embodiment, the first energy-saving signal for indicating not to wake up has a first waveform. For example, the first energy-saving signal is a single-frequency sine wave, and no information is modulated on the single-frequency sine wave.

[1148] In one possible design of this embodiment, the first energy-saving signal for indicating wake-up is a sequence modulated using a first modulation method. For example, the sequence using OOK modulation is 111000 or 101010, where 1 represents a high level of OOK and 0 represents a low level of OOK.

[1149] The modulation mode of the first energy-saving signal may also be FSK, PSK, etc., and the sequence length and sequence may also be other values, which are not limited in the embodiment of the present application.

[1150] In a possible design of this embodiment, the frequency of sending the first energy-saving signal is changed to indicate whether to wake up the WUR.

[1151] For example, the first energy-saving signal is sent at a first frequency point or a first frequency range, and the first frequency point or the first frequency range is used to indicate that the WUR is being woken up.

[1152] For another example, the first energy-saving signal is sent at the second frequency point or within the second frequency range, and the indication sent at the second frequency point or within the second frequency range is not to wake up the WUR.

[1153] The first frequency point and the second frequency point may be located in the same frequency band or in different frequency bands. The first frequency range and the second frequency range may be located in the same frequency band or in different frequency bands.

[1154] The electronic device measures the received signal energy at two frequency points or two frequency ranges through a peripheral circuit, thereby determining whether the first energy-saving signal is sent at the first frequency point or the second frequency point, or determining whether the first energy-saving signal is sent within the first frequency range or the second frequency range.

[1155] In a possible design of this embodiment, the electronic device further includes a second receiver, the first energy-saving signal is a signal received by the electronic device through the second receiver, and the operating energy consumption of the second receiver is less than the operating energy consumption of the first receiver.

[1156] In a possible design of this embodiment, the second receiver and the first receiver are on the same chip or on different chips and are connected via electronic leads.

[1157] In a possible design of this embodiment, the electronic device further includes a first circuit, and the first energy-saving signal is a signal received by the electronic device through the first circuit.

[1158] In a possible design of this embodiment, the first circuit includes a wireless energy harvesting circuit of an electronic device, or a peripheral circuit of a first receiver.

[1159] The wireless energy harvesting circuit is used for performing wireless energy harvesting. When the first receiver and the main transceiver are both turned off, the wireless energy harvesting circuit remains in operation and continues to perform wireless energy harvesting.

[1160] The electronic device measures the received signal energy at two frequency points or two frequency ranges through the first circuit, thereby determining whether the first energy-saving signal is sent at the first frequency point or the second frequency point, or determining whether the first energy-saving signal is sent within the first frequency range or the second frequency range.

[1161] In a possible design of this embodiment, the first receiver uses first receiver parameters, where the first receiver parameters include a first receiver type and / or a first receiving bandwidth.

[1162] The receiver type indicates the type of receiver architecture used by the electronic device, such as an RF-based receiver or an intermediate frequency (zero intermediate frequency)-based receiver; the reception bandwidth indicates the bandwidth used to receive signals.

[1163] In one possible design of this embodiment, the first receiver type is an RF-based receiver type. Using the first receiver type (RF envelope detection receiver type) directly detects the RF signal, eliminating the need for frequency conversion or conversion of the RF signal to a baseband signal. This reduces power consumption of the first receiver.

[1164] Since this receiver type can only receive the first energy-saving signal within a specified frequency range based on the implemented RF filter or matching network parameters, the first energy-saving signal can be received on the first frequency band or the first channel within the first frequency band.

[1165] In a possible design of this embodiment, the first sending module 2410 is used to send a first energy-saving signal in a first frequency band.

[1166] The receiving bandwidth of the first receiver is equal to the bandwidth of the first frequency band, and the first receiver receives the first energy-saving signal within a bandwidth range not exceeding the first frequency band, for example, the first energy-saving signal is received at 920 MHz to 925 MHz.

[1167] In a possible design of this embodiment, the first sending module 2410 is used to send a first energy-saving signal on a first channel in a first frequency band.

[1168] When the first frequency band includes multiple channels, the first energy-saving signal is transmitted on one of the channels (the first channel), and the receiving bandwidth of the first receiver is equal to the bandwidth of the first channel. For example, 20 channels with a bandwidth of 250 kHz are allocated within the 920 MHz to 925 MHz frequency band, and the first receiver receives the first energy-saving signal on the first channel.

[1169] For another example, when operating at 2.4 GHz, the frequency band is 2400 MHz to 2485 MHz, which can be divided into multiple channels, such as a channel from 2400 MHz to 2420 MHz, a channel from 2420 MHz to 2440 MHz, a channel from 2440 MHz to 2460 MHz, etc. Therefore, the first receiver can receive the first energy-saving signal on a first channel within the frequency band, such as a channel from 2400 MHz to 2420 MHz.

[1170] In a possible design of this embodiment, the first channel is any channel in the first frequency band; or,

[1171] The first channel is a designated channel in the first frequency band; or,

[1172] The first channel is the centralmost channel in the first frequency band; or

[1173] The first channel is one of the two central channels in the first frequency band.

[1174] When the number of channels included in the first frequency band is an odd number, the first channel is the most central channel in the first frequency band; when the number of channels included in the first frequency band is an even number, the first channel is one of the two most central channels in the first frequency band.

[1175] Exemplarily, when the first frequency band includes five channels, the first channel is the most central channel (the third channel); or, when the first frequency band includes four channels, the first channel is one of the two most central channels (the second channel or the third channel).

[1176] In a possible design of this embodiment, the second sending module 2420 is used to send a second energy-saving signal, and the second energy-saving signal is used to indicate whether to wake up the main transceiver.

[1177] In a possible design of this embodiment, waking up the main transceiver can also be equivalently understood as waking up the main transceiver; or can also be equivalently understood as waking up the main air interface communication unit. The above three expressions have the same meaning in the embodiment of this application.

[1178] In one possible design of this embodiment, waking up the master transceiver can also be equivalently understood as: monitoring the transmission of downlink data or data frames via the master transceiver; or equivalently understood as: monitoring the control channel used to schedule uplink data or downlink data or data frames via the master transceiver. The above three expressions have the same meaning in the embodiments of this application.

[1179] In one possible design of this embodiment, not waking up the primary transceiver can also be equivalently understood as: keeping the primary transceiver in a turned-off state; or can also be equivalently understood as: keeping the primary transceiver in a DRX monitoring state.

[1184] Different sequences;

[1185] Different frequencies used;

[1186] Different frequency ranges used;

[1187] The values ​​of the information bits carried are different.

[1188] For example, the first energy-saving signal has a first sequence or a second sequence, the first sequence being used to indicate waking up the first receiver, and the second sequence being used to indicate not waking up the first receiver. For example, the first sequence is ZC sequence (Zadoff-Chu sequence) 1, which is used to indicate waking up the first receiver, and the second sequence is ZC sequence 2, which is used to indicate not waking up the first receiver; this is not limited in the embodiments of the present application.

[1189] For another example, the first energy-saving signal has a first sequence length or a second sequence length, the first sequence length being used to indicate waking up the first receiver, and the second sequence length being used to indicate not waking up the first receiver. For example, the first sequence length is 16 bits, which is used to indicate waking up the first receiver, and the second sequence length is 8 bits, which is used to indicate not waking up the first receiver; or the first sequence length is 8 bits, which is used to indicate waking up the first receiver, and the second sequence length is 16 bits, which is used to indicate not waking up the first receiver; this embodiment of the present application is not limited to this.

[1190] In a possible design of this embodiment, the second sending module 2420 is used to send a second energy-saving signal to the first receiver after the first receiver is awakened.
