[0002] Currently, an electronic device can establish a wireless fidelity (Wi-Fi) connection with another device. After the electronic device establishes a Wi-Fi connection, it can receive Wi-Fi signals through the Wi-Fi connection. When the electronic device does not receive a Wi-Fi signal, it needs to listen to whether there is a Wi-Fi signal sent to the electronic device in the channel. Generally, the electronic device listens to the channel through the main channel in the electronic device.

[0003] Generally, when establishing a Wi-Fi connection, an electronic device will negotiate a set of transmission parameters with the highest performance (e.g., multi-antenna reception, high operating bandwidth (e.g., 80 MHz), high-order modulation and coding scheme (MCS) (e.g., MCS order is 11)) to configure the main channel. In this way, the electronic device consumes a lot of power. Summary of the invention

[0031] In one possible implementation, the second period is equal to the third period, and the second moment is different from the third moment. In this way, the duty cycle period of the wake-up frame sent by the first electronic device received by the second WUR receiver of the second electronic device is the same as the duty cycle period of the wake-up frame sent by the third electronic device. However, the start time of the duty cycle period of the wake-up frame sent by the first electronic device received by the second WUR receiver is different from the start time of the duty cycle period of the wake-up frame sent by the third electronic device.

The second electronic device can determine the WUR-related parameters of the second WUR receiver for receiving the WUR-related parameters sent by the third electronic device only through the second request frame.

[0076] In one possible implementation, the second period is equal to the third period, and the second moment is different from the third moment. In this way, the duty cycle period of the wake-up frame sent by the first electronic device received by the second WUR receiver of the second electronic device is the same as the duty cycle period of the wake-up frame sent by the third electronic device. However, the start time of the duty cycle period of the wake-up frame sent by the first electronic device received by the second WUR receiver is different from the start time of the duty cycle period of the wake-up frame sent by the third electronic device. In this way, the first electronic device and the third electronic device can be prevented from waking up the second main channel in the second electronic device at the same time, thereby avoiding traffic conflicts.

[0100] The terms used in the following embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to be used as limitations to the present application. As used in the specification and appended claims of the present application, the singular expressions "one", "a kind of", "said", "above", "the" and "this" are intended to also include plural expressions, unless there is a clear indication to the contrary in the context. It should also be understood that the term "and / or" used in the present application refers to and includes any or all possible combinations of one or more listed items.

[0101] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as suggesting or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features, and in the description of the embodiments of the present application, unless otherwise specified, "plurality" means two or more.

[0102] Currently, many electronic devices that establish Wi-Fi connections need to be powered by batteries in the electronic devices. In order to reduce the power consumption of the devices, the electronic devices can enter a sleep state. However, even in the sleep state, the terminal device needs to wake up from the sleep state from time to time to listen to and receive data sent by another electronic device (e.g., a wireless access point (AP)).

[0103] In some examples, in order to reduce the power consumption of the electronic device, a wake-up radio (WUR) receiver can be added to the electronic device. The power consumption specification of the WUR receiver is lower than the power consumption specification of the main channel in the electronic device. The electronic device can negotiate with the wireless access point (AP) to close the main channel in the electronic device when listening to the air interface, and use the WUR receiver to listen to the air interface. In this way, the power consumption of the electronic device can be reduced.

[0104] For example, Figure 1 FIG. 1 shows a WUR receiver and a main channel in an electronic device 100. Figure 1 As shown, the electronic device 100 may include a wake-up radio WUR receiver 101 , a main channel 102 , and an antenna 103 .

[0105] The power consumption specification of the WUR receiver 101 is lower than that of the main channel 102. Specifically, the working bandwidth of the WUR receiver 101 is smaller than the working bandwidth of the main channel 102, and / or the order of the modulation and coding scheme (MCS) that the WUR receiver 101 can support is smaller than the order of the MCS that the main channel 102 can support.

[0106] The MCS table can be shown in Table 1 below:

[0107] Table 1

[0108] The order of MCS Modulation Bitrate 0 BPSK 1 / 2 1 QPSK 1 / 2 2 QPSK 3 / 4 3 16-QAM 1 / 2 4 16-QAM 3 / 4 5 64-QAM 2 / 3 6 64-QAM 3 / 4 7 64-QAM 5 / 6 8 256-QAM 3 / 4 9 256-QAM 5 / 6 10 1024-QAM 3 / 4 11 1024-QAM 5 / 6

[0109] Among them, the modulation mode corresponding to MCS0 (also known as MCS order 0) is binary phase shift keying (BPSK), and the code rate is 1 / 2. The modulation mode corresponding to MCS1 is (quadrature phase shift keying, QPSK), and the code rate is 1 / 2. The modulation mode corresponding to MCS2 is QPSK, and the code rate is 1 / 2. The modulation mode corresponding to MCS3 is 16-symbol quadrature amplitude modulation (QAM) (16-QAM), and the code rate is 1 / 2. The modulation mode corresponding to MCS4 is 16-QAM, and the code rate is 3 / 4. The modulation mode corresponding to MCS5 is 64-symbol quadrature amplitude modulation (64-QAM), and the code rate is 2 / 3. The modulation mode corresponding to MCS6 is 64-QAM, and the code rate is 3 / 4. The modulation mode corresponding to MCS7 is 64-QAM, and the code rate is 5 / 6. The modulation mode corresponding to MCS8 is 256-symbol quadrature amplitude modulation (256-QAM), and the code rate is 2 / 3. The modulation mode corresponding to MCS9 is 256-QAM, and the code rate is 5 / 6. The modulation mode corresponding to MCS10 is 1024-symbol quadrature amplitude modulation (1024-QAM), and the code rate is 3 / 4. The modulation mode corresponding to MCS11 is 1024-QAM, and the code rate is 5 / 6.

[0110] Table 1 above only illustrates MCS in some Wi-Fi protocols. Other Wi-Fi protocols may have higher-order MCS, which is not limited in the embodiments of the present application.

[0111] In the embodiments of the present application, Figure 1 The WUR receiver 101 shown in the figure and the WUR receivers mentioned below may be modulated in an on-off keying (OOK) mode. OOK may also be called binary amplitude keying.

[0112] in, Figure 2 The relevant modules included in the main channel 102 are shown as an example. Figure 2As shown, the main channel 102 may include a Wi-Fi baseband chip (Wi-Fi baseband, Wi-Fi BB) 201, a receiving RF module (radio frequency receive, RF-RX) 202, a transmitting RF module (radio frequency transmit, RF-TX) 204, an analog-to-digital converter (ADC) 203, and a digital-to-analog converter (digital to analog converter, DAC) 205. The receiving channel composed of the receiving RF module 202 and the analog-to-digital converter 203 can be called the main receiving channel. The transmitting channel composed of the transmitting RF module 204 and the digital-to-analog converter 205 can be called the main transmitting channel.

[0113] When the electronic device 100 is in a sleep state, the WUR receiver 101 can be used to listen and receive via the antenna 103 a frame for waking up the electronic device (which can be called a WUR frame, or a wake-up frame, or a WUR wake-up frame, or a WUR wake-up packet, a WUR beacon frame, or a wake-up packet, etc., collectively referred to as a wake-up frame hereinafter).

[0114] When the WUR receiver 101 receives the wake-up frame, it can also be used to send a wake-up signal to the main channel 102.

[0115] When the main channel 102 receives the wake-up signal sent by the WUR receiver 101, the electronic device 100 can enter the awake state from the sleep state.

[0116] When the electronic device 100 is in the awake state, the main channel 102 can be used to send and receive Wi-Fi signals.

[0117] Among them, in the main transmission channel of the main channel 102, the digital-to-analog converter 205 can be used to convert the Wi-Fi signal output by the Wi-Fi baseband chip 201 into a Wi-Fi signal in the form of an analog signal, and then input the Wi-Fi signal in the form of an analog signal to the transmission RF module 204. The transmission RF module 204 can be used to convert the Wi-Fi signal in the form of an analog signal into a Wi-Fi signal in the form of an electromagnetic wave signal, amplify and modulate the Wi-Fi signal in the form of an electromagnetic wave signal, and then send it out through the antenna 103.

[0118] Among them, in the main receiving channel of the main channel 102, the receiving RF module 202 can be used to convert the Wi-Fi signal in the form of an electromagnetic wave signal received via the antenna 103 into a Wi-Fi signal in the form of an analog signal. The receiving RF module 202 can also amplify and demodulate the converted Wi-Fi signal in the form of an analog signal. The analog-to-digital converter 203 can be used to convert the Wi-Fi signal in the form of an analog signal converted by the receiving RF module 202 into a Wi-Fi signal in the form of a digital signal, and then input the Wi-Fi signal in the form of a digital signal to the Wi-Fi baseband chip 201.

[0119] Among them, in the main channel 102, the Wi-Fi baseband chip 201 can parse the physical frame based on the input Wi-Fi signal in the form of a digital signal. The Wi-Fi baseband chip 201 can also encode the physical frame to be sent into a Wi-Fi signal in the form of a digital signal, and convert it into an analog signal Wi-Fi signal through the digital-to-analog converter 205.

[0120] When the electronic device 100 does not send or receive data, the electronic device 100 may be in a dormant state. In an embodiment of the present application, when the electronic device 100 is in a dormant state, the main channel 102 is in a power-off state (or referred to as being in a closed state). The WUR receiver 101 is in a power-on state (or referred to as being in a working state) or is periodically in a power-on state.

[0121] Furthermore, in a possible implementation, when the electronic device 100 is in a sleep state, except for the WUR receiver 101 which is in a powered-on state (or called a working state) or periodically in a powered-on state, any device in the electronic device 100 may be in a powered-off state.

[0122] Further, in a possible implementation, if the electronic device 100 includes a volatile memory, the volatile memory may be in a powered-on state when the electronic device 100 is in a dormant state. Alternatively, before the electronic device 100 enters the dormant state, the electronic device 100 may copy the contents of the volatile memory to the non-volatile memory, and then power off the volatile memory and other devices except the WUR receiver 101 when entering the dormant state.

[0123] Optionally, when the electronic device 100 is in a sleep state, the main channel 102 being in a power-off state may include that the Wi-Fi baseband chip 201, the receiving RF module 202, the transmitting RF module 204, the analog-to-digital converter 203, the digital-to-analog converter 205 and other modules in the main channel 102 are all in a power-off state; or, some modules among the modules in the main channel 102, such as the Wi-Fi baseband chip 201, the receiving RF module 202, the transmitting RF module 204, the analog-to-digital converter 203, the digital-to-analog converter 205 and other modules are all in a power-off state are in a power-off state (for example, the Wi-Fi baseband chip 201, the receiving RF module 202, the transmitting RF module 204 in the main channel 102).

[0124] In the embodiment of the present application, the awake state is relative to the dormant state. When the electronic device 100 is in the awake state, the main channel 102 is in the powered-on state. Further, when the electronic device 100 is in the awake state, the WUR receiver 101 is in the powered-on state or is periodically in the powered-on state.

[0125] When the electronic device 100 is in a dormant state or an awake state, whether the WUR receiver 101 is always in a powered-on state or is periodically in a powered-on state is related to the WUR-related parameters of the WUR receiver 101 obtained by negotiation between the electronic device 100 and the AP. The WUR-related parameters of the WUR receiver 101 include the start time of the WUR receiver 101 being in the powered-on state, the duration of the WUR receiver 101 being in the powered-on state, and the period of the WUR receiver 101 being in the powered-on state. In Wi-Fi related protocols, the start time of the WUR receiver 101 being in the powered-on state is called the WUR duty cycle start time (WURdutycyclestarttime). The duration of the WUR receiver 101 being in the powered-on state can be called the WUR duty cycle service period (WURdutycycleserviceperiod). The period in which the WUR receiver 101 is in the powered-on state can be called the duty cycle period or the WUR duty cycle period (WURdutycycleperiod). The WUR duty cycle start time is also the start time of the duty cycle period. The WUR duty cycle service period can also be called the wake-up window duration.

[0126] Figure 3 The working mechanism of the WUR receiver 101 is shown as an example. Figure 3 As shown, the WUR receiver 101 ( Figure 3The start time of the WUR receiver 101 being in the power-on state is t0, the WUR duty cycle service period, that is, the wake-up window length is T2, and the duty cycle period is T1. T2 is less than or equal to T1. When T2 is less than T1, the WUR receiver 101 is periodically in the power-on state (also referred to as periodically turned on). When T2 is equal to T1, the WUR receiver 101 is always in the power-on state.

[0127] like Figure 3 As shown, the AP can send a wake-up frame to the electronic device 100 when the WUR receiver 101 is in a powered-on state. After receiving the wake-up frame, the WUR receiver 101 of the electronic device 100 can wake up the main channel (such as Figure 3 As shown, the primary channel may also be referred to as the primary connection radio (PCR).

[0128] The WUR-related parameters of the WUR receiver 101 (such as WUR duty cycle start time, WUR duty cycle service period, and duty cycle period, etc.) are negotiated and determined by the AP and the electronic device 100. In the Wi-Fi system constructed by the electronic device 100 and the AP, the electronic device 100 can also be called a station (STA).

[0129] Figure 4 The flowchart of the negotiation between the AP and the STA regarding WUR related parameters is shown as an example. Figure 4 As shown, the negotiation of WUR-related parameters between the AP and the STA may include the following steps:

[0130] S401. STA sends a WUR mode setting request frame to AP. The WUR mode setting request frame carries a duty cycle period field and a WUR duty cycle service period field.

[0131] When STA (which can be Figure 1 , Figure 3 In the process of establishing a Wi-Fi connection between the electronic device 100 shown in FIG. 1 and the AP, the STA can establish an association with the AP. After the STA completes the association with the AP, the STA can send a WUR mode setting request frame (WUR mode setup frame (request), or WUR mode setup request frame) to the AP.

[0132] The WUR mode setting request frame may include a duty cycle field and a WUR duty cycle service period field. For example, the duty cycle field may be used to indicate that the duty cycle of the WUR receiver in the STA is T1. The WUR duty cycle service period field may be used to indicate that the wake-up window length in the STA is T2.

[0133] The WUR mode setting request frame may also include other fields, which are not limited in the embodiments of the present application. The specific format of the WUR mode setting request frame can refer to the description in the existing protocol, which will not be repeated here.

[0134] S402. AP sends a WUR mode setting response frame to STA. The WUR mode setting response frame carries a WUR duty cycle start time field and a WUR channel offset field.

[0135] After the AP receives the WUR mode setting request frame sent by the STA, the AP may reply to the STA with a WUR mode setting response frame (WUR modesetupframe(response) or WUR modesetupresponse frame).

[0136] The WUR mode setting response frame may include a WUR duty cycle start time field and a WUR channel offset field. For example, the WUR duty cycle start time field may be used to indicate the WUR receiver 101 ( Figure 3 The start time of the duty cycle of the WUR receiver 101 (ie, the WUR receiver 101 is in the power-on state) is t0. The WUR channel offset field can be used to indicate the channel offset.

[0137] The WUR mode setting response frame may also include other fields, which are not limited in the embodiments of the present application. The specific format of the WUR mode setting response frame can refer to the description in the existing protocol, which will not be repeated here.

[0138] Optionally, in some examples, the STA may negotiate relevant parameters of the WUR receiver 101 with the AP when establishing an association. Specifically, when the STA and the AP establish an association, the STA may send an association request (association request) to the AP, and the AP may reply with an association response (association response) to the STA. Among them, the association request may carry a duty cycle period field and a WUR duty cycle service period field. Exemplarily, the duty cycle period field may be used to indicate that the duty cycle of the WUR receiver in the STA is T1. The WUR duty cycle service period field may be used to indicate that the wake-up window length in the STA is T2. The association response may carry a WUR duty cycle start time field and a WUR channel offset field. Exemplarily, the WUR duty cycle start time field may be used to indicate that the WUR receiver 101 ( Figure 3 The start time of the power-on state of the wireless communication device (abbreviated as WUR) is t0. The WUR channel offset field can be used to indicate the channel offset.

[0139] In the existing protocol, in a Wi-Fi system composed of AP and STA, only one end (STA) device is supported to sleep and wake up the device through a wake-up frame. In this way, only the power consumption of the device at one end can be saved, but the power consumption of the devices at both ends cannot be saved.

[0140] The embodiment of the present application provides a power consumption control system, in which the system may include a first electronic device and a second electronic device, the first electronic device can sleep, and can enter a wake-up state from the sleep state through a wake-up frame sent by the second electronic device. The second electronic device can also sleep, and can enter a wake-up state from the sleep state through a wake-up frame sent by the first electronic device. In this way, the first electronic device and the second electronic device in the system can both save power consumption.

[0141] Figure 5 The system 10 provided by the embodiment of the present application is exemplarily shown. Figure 5 As shown, the system 10 may include an electronic device 100, an electronic device 200 and an electronic device 300. Among them:

[0142] The electronic device 100 may establish a Wi-Fi connection with the electronic device 200 , and the electronic device 300 may also establish a Wi-Fi connection with the electronic device 200 .

[0143] In a possible implementation, the electronic device 100 and the electronic device 200 establish Wi-Fi Direct, and the electronic device 300 can also establish Wi-Fi Direct with the electronic device 200. Wi-Fi Direct may include a peer-to-peer (P2P) connection, a soft access point (softAP) connection, etc. For P2P connection and softAP, please refer to the introduction in the existing protocol, which will not be repeated here.

[0144] Exemplarily, the electronic device 100 and the electronic device 300 can establish a P2P connection, and the electronic device 200 and the electronic device 300 can establish a P2P connection. In the P2P group group formed by the electronic device 100, the electronic device 200 and the electronic device 300, one of the electronic devices 100, the electronic device 200 and the electronic device 300 can be used as a group owner (groupowner, GO) device, and the other devices can be called group client (groupclient, GC) devices. For example, the electronic device 200 can be called a GO device, and the electronic device 100 and the electronic device 300 can be called GC devices.

[0145] Optionally, in a possible implementation, the electronic device 200 may establish a Wi-Fi connection with the electronic device 100. In the Wi-Fi network formed by the electronic device 200 and the electronic device 100, the electronic device 200 may be a STA and the electronic device 100 may be an AP. Then the electronic device 200 may also establish a P2P connection with the electronic device 300.

[0146] It is understandable that the embodiment of the present application does not limit the networking method of the electronic device 100, the electronic device 200, and the electronic device 300.

[0147] The electronic device 100 may include a wake-up radio WUR receiver 101, a main channel 102, and an antenna 103. For a detailed description of the wake-up radio WUR receiver 101, the main channel 102, and the antenna 103 in the electronic device 100, please refer to the above description of Figure 1 The description in will not be repeated here.

[0148] The electronic device 100 may be in a dormant state. When the electronic device 100 is in a dormant state, the main channel 102 of the electronic device 100 may be in a power-off state, and the WUR receiver 101 in the electronic device 100 may receive the wake-up frame 2 sent by the electronic device 200 via the antenna 103. After receiving the wake-up frame 2, the WUR receiver 101 in the electronic device 100 may send a wake-up signal 1 to the main channel 102 to wake up the main channel 102 (i.e., change the main channel 102 from a power-off state to a power-on state).

[0149] The electronic device 200 may include a wake-up radio WUR receiver 105, a main channel 104, and an antenna 106. The power consumption specification of the WUR receiver 105 is lower than the power consumption specification of the main channel 104. Specifically, the operating bandwidth of the WUR receiver 105 is smaller than the operating bandwidth of the main channel 104, and / or the order of MCS that the WUR receiver 105 can support is smaller than the order of MCS that the main channel 104 can support.

[0150] For the WUR receiver 105 , please refer to the above description of the WUR receiver 101 , and for the main channel 104 , please refer to the above description of the main channel 102 , which will not be repeated here.

[0151] The electronic device 200 may be in a dormant state. When the electronic device 200 is in a dormant state, the main channel 104 of the electronic device 200 may be in a power-off state, and the WUR receiver 105 in the electronic device 200 may receive the wake-up frame 1 sent by the electronic device 100 via the antenna 106. After receiving the wake-up frame 1, the WUR receiver 105 in the electronic device 200 may send a wake-up signal 2 to the main channel 104 to wake up the main channel 104 (i.e., change the main channel 104 from the power-off state to the power-on state).

[0152] The electronic device 300 may include a main channel 107 and an antenna 109. Optionally, the electronic device 300 may include a wake-up radio WUR receiver 108.

[0153] The main channel 107 of the electronic device 300 can send a wake-up frame 3 to the electronic device 200 via the antenna 109. When the electronic device 200 is in a dormant state, the WUR receiver 105 in the electronic device 200 can receive the wake-up frame 3 sent by the electronic device 300 via the antenna 106. After receiving the wake-up frame 3, the WUR receiver 105 in the electronic device 200 can send a wake-up signal 2 to the main channel 104 to wake up the main channel 104 (i.e., change the main channel 104 from a power-off state to a power-on state).

[0154] The electronic device 100 , the electronic device 200 and the electronic device 300 may be a mobile phone, a tablet computer, a personal digital assistant (PDA), a car computer, etc.

[0155] Through the system 10 provided in the embodiment of the present application, both the electronic device 100 and the electronic device 200 can put the main channel into sleep mode, and then wake up the main channel after receiving the wake-up frame sent by the opposite end through the WUR receiver. In this way, the power consumption of the electronic device 100 and the electronic device 200 can be saved.

[0156] When there are multiple links in the system 10, the electronic device 200 can put the main channel into sleep mode, and then wake up the main channel after receiving the wake-up frame sent by the electronic device 100 or the electronic device 300 through the WUR receiver 105. In this way, the power consumption of the electronic device 200 can be saved, and when the electronic device 100 or the electronic device 300 has data to be sent to the electronic device 200, the electronic device 200 can be woken up and the data can be sent to the electronic device 200 in a timely manner.

[0157] In the embodiment of the present application, the first electronic device may be the electronic device 100, the second electronic device may be the electronic device 200, and the third electronic device may be the electronic device 300. The first main channel may be the main channel 102, and the first WUR receiver may be the WUR receiver 101. The second main channel may be the main channel 104, and the second WUR receiver may be the WUR receiver 105. The third main channel may be the main channel 107.

[0158] Combine the following Figure 6-Figure 10 The working mechanism of the WUR receiver in the electronic device 100 and the electronic device 200 is introduced in detail when both the electronic device 100 and the electronic device 200 are equipped with the WUR receiver.

[0159] Figure 6 The schematic diagram of the mutual awakening process of the electronic device 100 and the electronic device 200 is exemplarily shown. Figure 6 As shown, both the electronic device 100 and the electronic device 200 are equipped with a WUR receiver and a main channel. Before the main channels of the electronic device 100 and the electronic device 200 go into hibernation, the electronic device 100 can negotiate WUR-related parameters with the electronic device 200. The WUR-related parameter negotiation process will be Figure 7 ,and Fig.10 I will not go into details here.

[0160] After the electronic device 100 and the electronic device 200 have negotiated the WUR related parameters, the main channel of the electronic device 100 can be dormant, and the WUR receiver in the electronic device 100 begins to periodically listen to and receive the wake-up frame sent by the electronic device 200 according to the negotiated WUR related parameters. Figure 6 As shown, the WUR duty cycle start time of the WUR receiver in the electronic device 100 may be t0, the duty cycle period of the WUR receiver may be T1, and the wake-up window length of the WUR receiver may be T2. When there is a data packet to be sent to the electronic device 200 in the sending queue of the electronic device 100, the electronic device 100 may first wake up the main channel, and then send a wake-up frame through the main channel to wake up the electronic device 200.

[0161] like Figure 6 As shown, when the main channels of the electronic device 100 and the electronic device 200 are both in sleep mode, the electronic device 100 sending a data packet to the electronic device 200 may specifically include the following steps:

[0162] ①. The electronic device 100 wakes up the primary connection radio (PCR) of the electronic device 100.

[0163] The PCR in the electronic device 100 may be in a dormant state (also referred to as a power-off state or closed). When there is a data packet in the electronic device 100 that needs to be sent to the electronic device 200, the system of the electronic device 100 may wake up the PCR of the electronic device 100, that is, the system of the electronic device 100 may turn on the PCR, that is, power on the PCR.

[0164] The PCR may also be referred to as a main channel, that is, the PCR of the electronic device 100 may be the main channel 102 mentioned above.

[0165] ②. The PCR of the electronic device 100 sends a wake-up frame 1 to the WUR of the electronic device 200.

[0166] When the PCR of the electronic device 100 is turned on (i.e., it becomes powered on), a wake-up frame 1 can be sent to the WUR receiver of the electronic device 200. The wake-up frame 1 is used to instruct the WUR in the electronic device 200 to wake up the PCR in the electronic device 200. The format of the wake-up frame 1 can refer to the introduction of the WUR wake-up frame in the existing protocol, which will not be repeated here.

[0167] ③. The WUR of the electronic device 200 wakes up the PCR of the electronic device 200.

[0168] After receiving the wake-up frame 1, the WUR receiver of the electronic device 200 may send a wake-up signal 1 to the PCR of the electronic device 200. The wake-up signal 1 may instruct the electronic device 200 to change the PCR from a power-off state to a power-on state, that is, instruct the electronic device 200 to power on the PCR.

[0169] When the PCR of the electronic device 200 is awakened, the PCR of the electronic device 200 may send a message 1 to the PCR of the electronic device 100. The message 1 may be used to indicate that the PCR of the electronic device 200 has been awakened.

[0170] ④. The PCR of electronic device 100 sends data packet 1 to the PCR of electronic device 200.

[0171] After the PCR of the electronic device 100 receives the message 1, the PCR of the electronic device 100 may send the data packet 1 to the PCR of the electronic device 200. When the PCR in the electronic device 100 has sent the data packet 1 and no longer needs to transmit data, the PCR in the electronic device 100 may enter the dormant state again.

[0172] The PCR in the electronic device 200 can receive the data packet 1. When the PCR in the electronic device 200 has received the data packet 1 and no longer needs to transmit data, the PCR in the electronic device 200 can enter the dormant state again.

[0173] After the electronic device 100 and the electronic device 200 have negotiated the WUR related parameters, the main channel of the electronic device 200 can be dormant, and the WUR receiver in the electronic device 200 begins to periodically listen to and receive the wake-up frame sent by the electronic device 100 according to the negotiated WUR related parameters. Figure 6 As shown, the WUR duty cycle start time of the WUR receiver in the electronic device 200 may be t0, the duty cycle period of the WUR receiver may be T1, and the WUR duty cycle service period of the WUR receiver may be T2. When there is a data packet sent to the electronic device 200 in the sending queue of the electronic device 200, the electronic device 200 may first wake up the main channel, and then send a wake-up frame through the main channel to wake up the electronic device 100.

[0174] It is understandable that the WUR-related parameters in the electronic device 200 may be the same as or different from the WUR-related parameters in the electronic device 100.

[0175] In some examples, the WUR duty cycle start time of the WUR receiver in electronic device 200 is different from the WUR duty cycle start time of the WUR receiver in electronic device 100, and / or the duty cycle period of the WUR receiver in electronic device 200 is different from the duty cycle period of the WUR receiver in electronic device 100, and / or the WUR duty cycle service period of the WUR receiver in electronic device 200 is different from the WUR duty cycle service period of the WUR receiver in electronic device 100.

[0176] Figure 6 The following explanation is given by taking the example that the WUR-related parameters such as the WUR duty cycle start time, duty cycle period, and WUR duty cycle service period of the WUR receiver in the electronic device 200 are the same as the WUR-related parameters such as the WUR duty cycle start time, duty cycle period, and WUR duty cycle service period of the WUR receiver in the electronic device 100.

[0177] like Figure 6 As shown, when the main channels of the electronic device 200 and the electronic device 100 are both in sleep mode, the electronic device 200 sending a data packet to the electronic device 100 may specifically include the following steps:

[0178] ①. The electronic device 200 wakes up the PCR of the electronic device 200.

[0179] After the electronic device 200 and the electronic device 100 have negotiated the WUR-related parameters of the electronic device 200, the electronic device 200 can power off the PCR and power on the WUR receiver at the WUR duty cycle start time of the WUR receiver in the electronic device 200. That is, at the moment when the WUR in the negotiated electronic device 200 starts working, the PCR is powered off and the WUR receiver is powered on.

[0180] Alternatively, the electronic device 200 may also power off the PCR immediately after negotiating the WUR related parameters. Then, when the WUR in the negotiated electronic device 200 starts working, the WUR receiver is powered on.

[0181] When the PCR in the electronic device 200 is powered off, the PCR of the electronic device 200 is said to be in a dormant state. When there is a data packet in the electronic device 200 that needs to be sent to the electronic device 100, the system of the electronic device 200 can wake up the PCR of the electronic device 200. That is, the system of the electronic device 200 can turn on the PCR, that is, power on the PCR.

[0182] The PCR of the electronic device 200 may be the main channel 104 mentioned above.

[0183] ②. The PCR of the electronic device 200 sends a wake-up frame 2 to the WUR of the electronic device 100.

[0184] When the PCR of the electronic device 200 is powered on, a wake-up frame 2 may be sent to the WUR receiver of the electronic device 100. The wake-up frame 2 may be used to instruct the WUR receiver of the electronic device 100 to wake up the PCR in the electronic device 100.

[0185] ③. The WUR of the electronic device 100 wakes up the PCR of the electronic device 100.

[0186] After receiving the wake-up frame 2, the WUR receiver of the electronic device 100 may send a wake-up signal 2 to the PCR of the electronic device 100. The wake-up signal 2 may be used to instruct the electronic device 100 to change the PCR from a power-off state to a power-on state, that is, to instruct the electronic device 100 to power on the PCR.

[0187] When the PCR of the electronic device 100 is awakened, the PCR of the electronic device 100 may send a message 2 to the PCR of the electronic device 200. The message 2 may be used to indicate that the PCR of the electronic device 100 has been awakened.

[0188] ④. The PCR of electronic device 200 sends data packet 2 to the PCR of electronic device 100.

[0189] After the PCR of the electronic device 200 receives the message 2, the PCR of the electronic device 200 can send the data packet 2 to the PCR of the electronic device 100. When the PCR in the electronic device 200 has sent the data packet 2 and does not need to transmit data, the PCR of the electronic device 200 can enter the dormant state again.

[0190] The PCR in the electronic device 100 can receive the data packet 2. When the PCR in the electronic device 100 has received the data packet 2 and does not need to transmit data anymore, the PCR in the electronic device 100 can enter the dormant state again.

[0191] The following will be combined Figure 7-10 The process of negotiating WUR related parameters between the electronic device 100 and the electronic device 200 is described in detail.

[0192] In a possible implementation, the electronic device 100 and the electronic device 200 may negotiate WUR-related parameters twice. One time is when the electronic device 100 actively sends a WUR mode setting request frame to determine the duty cycle of the WUR receiver in the electronic device 100, and the WUR duty cycle service period. The other time is when the electronic device 200 actively sends a WUR mode setting request frame to determine the duty cycle of the WUR receiver in the electronic device 200, and the WUR duty cycle service period. See below for details. Figure 7 Description.

[0193] Figure 7 A schematic diagram of a process of negotiating WUR related parameters between the electronic device 100 and the electronic device 200 is shown as an example. Figure 7 As shown, the electronic device 100 and the electronic device 200 may negotiate WUR-related parameters including the following steps:

[0194] S701. The electronic device 200 sends a WUR mode setting request frame 1 to the electronic device 100. The WUR mode setting request frame 1 carries a duty cycle field 1 and a WUR duty cycle service period field 1. The duty cycle field 1 is used to indicate that the duty cycle is T1, and the WUR duty cycle service period field 1 is used to indicate that the wake-up window length is T2.

[0195] S702. The electronic device 100 sends a WUR mode setting response frame 1 to the electronic device 200. The WUR mode setting response frame 1 carries a WUR duty cycle start time field 1 and a WUR channel offset field 1. The WUR duty cycle start time field 1 is used to indicate that the WUR duty cycle start time is t0, and the WUR channel offset field 1 is used to indicate that the WUR channel offset is offset1.

[0196] After the electronic device 100 completes the association with the electronic device 200, the electronic device 200 may negotiate with the electronic device 100 about the relevant parameters of the WUR receiver in the electronic device 200. Exemplarily, as described in step S701, the electronic device 200 may send a WUR mode setting request frame 1 to the electronic device 100. The WUR mode setting request frame 1 may carry a duty cycle field 1 and a WUR duty cycle service period field 1. Among them, the duty cycle field 1 may be used to indicate that the duty cycle is T1. The WUR duty cycle service period field 1 may be used to indicate that the wake-up window length is T2.

[0197] After the electronic device 100 receives the WUR mode setting request frame 1 sent by the electronic device 200, as described in step S702, the electronic device 100 may reply to the electronic device 200 with a WUR mode setting response frame 1. The WUR mode setting response frame 1 may carry a WUR duty cycle start time field 1 and a WUR channel offset field 1. Among them, the WUR duty cycle start time field 1 may be used to indicate that the WUR duty cycle start time is t0. The WUR channel offset field 1 may be used to indicate that the WUR channel offset is offset1.

[0198] When the electronic device 100 and the electronic device 200 negotiate the WUR-related parameters of the WUR receiver in the electronic device 200 according to the above steps S701 and S702, the electronic device 200 can act as the STA role in the Wi-Fi network, and the electronic device 100 can act as the AP role in the Wi-Fi network. That is, the steps performed by the electronic device 200 can refer to the above steps. Figure 4 The steps performed by the STA are described in the above description; the steps performed by the electronic device 100 can refer to the above Figure 4 The description of the steps performed by the AP in is not repeated here.

[0199] After the electronic device 200 and the electronic device 100 have negotiated the WUR-related parameters of the WUR receiver in the electronic device 200, the WUR receiver in the electronic device 200 can start to power on at time t0, and the duration in the power-on state is T2, and the cycle of each power-on start is T1. The electronic device 100 can send a wake-up frame to the WUR receiver in the electronic device 200 starting from time t0 within the duration of T2. In this way, the electronic device 200 turns on the WUR receiver and listens for and receives the wake-up frame according to the negotiated WUR-related parameters, and the electronic device 100 sends the wake-up frame only when the WUR receiver in the electronic device 200 is in the power-on state according to the negotiated WUR-related parameters. In this way, it can be avoided that the electronic device 100 sends a wake-up frame when the WUR receiver is not turned on. In addition, the WUR receiver in the electronic device 200 can determine the channel for receiving the wake-up frame according to the WUR channel offset offset1. Moreover, the main channel in the electronic device 200 can be put into sleep mode after the parameters are negotiated, and the main channel will be awakened only after the WUR receiver receives the wake-up frame, which can save the power consumption of the electronic device 200.

[0200] S703, the electronic device 100 sends a WUR mode setting request frame 2 to the electronic device 200. The WUR mode setting request frame 2 carries a duty cycle field 2 and a WUR duty cycle service period field 2. The duty cycle field 2 is used to indicate that the duty cycle is T3, and the WUR duty cycle service period field 2 is used to indicate that the wake-up window length is T4.

[0201] S704. The electronic device 200 sends a WUR mode setting response frame 2 to the electronic device 100. The WUR mode setting response frame 2 carries a WUR duty cycle start time field 2 and a WUR channel offset field 2. The WUR duty cycle start time field 2 is used to indicate that the WUR duty cycle start time is t1, and the WUR channel offset field 2 is used to indicate that the WUR channel offset is offset2.

[0202] After the electronic device 100 completes the association with the electronic device 200, the electronic device 100 may also negotiate with the electronic device 200 about the relevant parameters of the WUR receiver in the electronic device 100. Exemplarily, as described in step S703, the electronic device 100 may send a WUR mode setting request frame 2 to the electronic device 200. The WUR mode setting request frame 2 may carry a duty cycle field 2 and a WUR duty cycle service period field 2. Among them, the duty cycle field 2 may be used to indicate that the duty cycle is T3. The WUR duty cycle service period field may be used to indicate that the wake-up window length is T4.

[0203] After the electronic device 200 receives the WUR mode setting request frame 2 sent by the electronic device 100, as described in step S704, the electronic device 200 may reply to the electronic device 100 with a WUR mode setting response frame 2. The WUR mode setting response frame 2 may carry a WUR duty cycle start time field 2 and a WUR channel offset field 2. Among them, the WUR duty cycle start time field 2 may be used to indicate that the WUR duty cycle start time is t1. The WUR channel offset field 2 may be used to indicate that the WUR channel offset is offset2.

[0204] When the electronic device 100 and the electronic device 200 negotiate the WUR-related parameters of the WUR receiver in the electronic device 100 according to the above steps S703 and S704, the electronic device 100 can act as the STA role in the Wi-Fi network, and the electronic device 200 can act as the AP role in the Wi-Fi network. That is, when the electronic device 100 and the electronic device 200 negotiate the WUR-related parameters of the WUR receiver in the electronic device 100, the steps performed by the electronic device 100 can refer to the above steps. Figure 4 The steps performed by the STA are described in the above description; the steps performed by the electronic device 200 can refer to the above Figure 4 The description of the steps performed by the AP in is not repeated here.

[0205] After the electronic device 100 and the electronic device 200 have negotiated the WUR-related parameters of the WUR receiver in the electronic device 100, the WUR receiver in the electronic device 100 can start to power on at time t1, and the duration in the power-on state is T4, and the cycle of each power-on start is T3. The electronic device 200 can send a wake-up frame to the WUR receiver in the electronic device 200 starting from time t1 within the duration of T4. In this way, the electronic device 100 turns on the WUR receiver and listens for and receives the wake-up frame according to the negotiated WUR-related parameters, and the electronic device 200 only sends the wake-up frame when the WUR receiver in the electronic device 100 is in the power-on state according to the negotiated WUR-related parameters. In this way, it can be avoided that the electronic device 200 sends a wake-up frame when the WUR receiver is not turned on. In addition, the WUR receiver in the electronic device 100 can determine the channel for receiving the wake-up frame according to the WUR channel offset offset2. Moreover, the main channel in the electronic device 100 can be put into sleep mode after the parameters are negotiated, and the main channel will be awakened only after the WUR receiver receives a wake-up frame, which can save power consumption of the electronic device 100.

[0206] It can be understood that the embodiment of the present application does not limit the execution order of the electronic device 100 and the electronic device 200 negotiating the relevant parameters of the WUR receiver in the electronic device 100, and the electronic device 200 and the electronic device 100 negotiating the relevant parameters of the WUR receiver in the electronic device 200. That is, the electronic device 100 and the electronic device 200 can first execute step S701 and step S702, and then execute step S703 and step S704. The electronic device 100 and the electronic device 200 can also first execute step S703 and step S704, and then execute step S701 and step S702. The embodiment of the present application does not limit this.

[0207] In the embodiment of the present application, the relevant parameters of the WUR receiver in the electronic device 100 and the relevant parameters of the WUR receiver in the electronic device 200 may be the same or different.

[0208] Exemplarily, in a possible implementation, the WUR duty cycle start time t1 may be the same as the WUR duty cycle start time t0, that is, t1 may be equal to t0. The duty cycle period T3 may be the same as the duty cycle period T1, that is, T3 may be equal to T1. The WUR duty cycle service period T4 may be the same as the WUR duty cycle service period T2, that is, T4 may be equal to T1. That is, the start of operation of the WUR receiver in the power-on state, the duration of being in the power-on state, and the period of being in the power-on state in the electronic device 100 and the start of operation of the WUR receiver in the power-on state, the duration of being in the power-on state, and the period of being in the power-on state in the electronic device 200 may be the same. In addition, the WUR channel offset offset1 may be the same as the WUR channel offset, or it may be different. In this way, the electronic device 100 and the electronic device 200 have the same sleep time. When the PCR of the electronic device 100 is in sleep mode, the PCR of the electronic device 200 is also in sleep mode. In this way, the power consumption of the electronic device 100 and the electronic device 200 can be saved.

[0209] For example, Figure 8 The schematic diagram shows that the start time, duration, and period of the WUR receiver in the power-on state in the electronic device 100 are the same as the start time, duration, and period of the WUR receiver in the power-on state in the electronic device 200. Figure 8 As shown, the WUR duty cycle start time (also referred to as the start time) of the WUR receiver in the electronic device 100 is t0, the duty cycle period is T1, and the WUR duty cycle service period is T2. The start time of the WUR receiver in the electronic device 200 is t0, the duty cycle period is T1, and the WUR duty cycle service period is T2.

[0210] Optionally, in another possible implementation, the WUR duty cycle start time t1 may be different from the WUR duty cycle start time t0, that is, t1 may not be equal to t0. The duty cycle period T3 may be the same as the duty cycle period T1.

[0211] For example, Fig. 9 Schematic diagram of a scenario in which the start time of the WUR receiver in the electronic device 100 being powered on is different from the start time of the WUR receiver in the electronic device 200 being powered on. Fig. 9 As shown, the WUR duty cycle start time (also referred to as the start time) of the WUR receiver is t0, the duty cycle period is T1, and the WUR duty cycle service period is T2. The start time of the WUR receiver in the electronic device 200 is t1, the duty cycle period is T3, and the WUR duty cycle service period is T4.

[0212] like Fig. 9 As shown, t0 is not equal to t1. Optionally, t1 is greater than or equal to M1, and M1 is the sum of t0 and T1.

[0213] like Fig. 9 As shown, T1 can be equal to T3. Optionally, the sum of T2 and T4 can be equal to T1 (also equal to T3), or less than T1, which is not limited here. T2 and T4 can be equal or unequal, and the size of T2 and T4 is not limited here.

[0214] In this way, the PCR wake-up time in the electronic device 100 and the PCR wake-up time in the electronic device 200 can be staggered, thereby reducing the conflict of the electronic device 100 and the electronic device 200 sending data to the opposite end device at the same time, and staggering the traffic.

[0215] Optionally, in a possible implementation, the electronic device 100 and the electronic device 200 may negotiate WUR-related parameters only once. Then, the WUR receiver in the electronic device 100 and the WUR receiver in the electronic device 200 both listen and receive the wake-up frame according to the negotiated WUR-related parameters.

[0216] Fig.10 Another flow chart of the negotiation of WUR related parameters between the electronic device 100 and the electronic device 200 is shown as an example. Fig.10 As shown, the electronic device 100 and the electronic device 200 may negotiate WUR-related parameters including the following steps:

[0217] S1001. The electronic device 200 sends a WUR mode setting request frame 1 to the electronic device 100. The WUR mode setting request frame 1 carries a duty cycle field 1 and a WUR duty cycle service period field 1. The duty cycle field 1 is used to indicate that the duty cycle is T1, and the WUR duty cycle service period field 1 is used to indicate that the wake-up window length is T2.

[0218] S1002. The electronic device 100 sends a WUR mode setting response frame 1 to the electronic device 200. The WUR mode setting response frame 1 carries a WUR duty cycle start time field 1 and a WUR channel offset field 1. The WUR duty cycle start time field 1 is used to indicate that the WUR duty cycle start time is t0, and the WUR channel offset field 1 is used to indicate that the WUR channel offset is offset1.

[0219] Step S1001 and step S1002 may refer to the description of the above-mentioned step S701 and step S702, which will not be repeated here.

[0220] After the electronic device 100 establishes an association with the electronic device 200, the electronic device 200 can negotiate WUR related parameters with the electronic device 100. When the electronic device 100 establishes a Wi-Fi P2P connection with the electronic device 200, if in the P2P group, the electronic device 100 is a GO device and the electronic device 200 is a GC device. Then the electronic device 200 can perform the above step S1001 as a STA in the Wi-Fi network, and the electronic device 100 can perform the above step S1002 as an AP in the Wi-Fi network.

[0221] Optionally, when in a P2P group, the electronic device 200 is a GO device and the electronic device 100 is a GC device, the electronic device 100 can perform the above step S1001 as a STA in a Wi-Fi network, and the electronic device 200 can perform the above step S1002 as an AP in a Wi-Fi network. That is, the electronic device 100 sends a WUR mode setting request frame, which can carry a duty cycle period field and a WUR duty cycle service period field. Then, the electronic device 200 replies with a WUR mode setting response frame, which can carry a WUR duty cycle start time field and a WUR channel offset field.

[0222] Optionally, when the electronic device 100 and the electronic device 200 establish an association or before establishing an association, the device information (for example, the remaining power, whether it is an active device, etc.) can be exchanged, and then the electronic device 100 and the electronic device 200 can determine which of the electronic devices 100 and 200 has more power or is an active device, or an electronic device that is the service initiator to perform the above Figure 4 The steps performed by the AP in the above step are to reply to the WUR mode setting response frame. In step S1001 and step S1002, the electronic device 100 is a device with more power or an active device, or is a service initiator. The electronic device 100 can perform the above steps. Figure 4 The steps performed by the AP in the process are to reply to the WUR mode setting response frame.

[0223] Optionally, the electronic device 200 may be the electronic device with more power or an active device, or the electronic device that initiates the service. The electronic device 200 may perform the following steps: Figure 4 The steps performed by the AP in the process are to reply with a WUR mode setting response frame.

[0224] When the electronic device 100 and the electronic device 200 negotiate once to obtain WUR related parameters, for example, the WUR related parameters include: WUR duty cycle start time t0, duty cycle period T1, WUR duty cycle service period T2, and WUR channel offset offset1. The WUR receiver in the electronic device 100 and the WUR receiver in the electronic device 200 are both powered on at the start time t0, the duration in the powered-on state is T2, and the working period in the powered-on state is T1. For details, please refer to Figure 8 The description in will not be repeated here.

[0225] Optionally, when the electronic device 100 and the electronic device 200 negotiate WUR related parameters according to the above steps S1001 and S1002, the WUR duty cycle start time t0, the duty cycle period T1, the WUR duty cycle service period T2, and the WUR channel offset offset1 are obtained. Then, the electronic device 100 or the electronic device 200 can derive another set of WUR related parameters according to the WUR duty cycle start time t0, the duty cycle period T1, the WUR duty cycle service period T2, and the WUR channel offset offset1.

[0226] Exemplarily, the WUR receiver in the electronic device 200 can listen and receive wake-up frames according to the negotiated WUR-related parameters. The electronic device 100 can derive another set of WUR-related parameters based on the WUR duty cycle start time t0, the duty cycle period T1, the WUR duty cycle service period T2, and the WUR channel offset offset1. The WUR duty cycle start time derived by the electronic device 100 is (t0+(x1 / x2)T2), where " / " represents division, and x1 is less than or equal to x2. The duty cycle period derived by the electronic device 100 can be x3T1, where x3 is a positive number greater than 0, for example, x3 can be 1. The WUR duty cycle service period derived by the electronic device 100, that is, the wake-up window length is (T1-(x4 / x5)T2), where x4 is less than or equal to x5. The embodiments of the present application do not limit the specific values ​​of x1, x2, x3, x4, and x5.

[0227] For example, the WUR related parameters derived by the electronic device 100 may be: WUR duty cycle start time t1 (i.e. t1 = (t0 + (x1 / x2)T2)), duty cycle period T3 (i.e. T3 = x3T1), WUR duty cycle service period T4 (i.e. T4 = (T1-(x4 / x5)T2)), and WUR channel offset is offset1. Then, the electronic device 100 may send an action frame to the electronic device 200, and the action frame may include a WUR duty cycle start time field, a duty cycle period field, a WUR duty cycle service period field, and a WUR channel offset field. Among them, the WUR duty cycle start time field may be used to indicate that the WUR duty cycle start time is t0. The duty cycle period field may be used to indicate that the duty cycle period is T3. The WUR duty cycle service period field may be used to indicate the WUR duty cycle service period, that is, the wake-up window length is T4. The WUR channel offset field is used to indicate that the WUR channel offset is offset1. That is, the electronic device 100 can inform the electronic device 200 of the WUR-related parameters of the WUR receiver in the electronic device 100 through the action frame. Then, the electronic device 200 can send a wake-up frame to the WUR receiver of the electronic device 100 when the WUR receiver in the electronic device 100 is in a powered-on state according to the WUR-related parameters of the WUR receiver in the electronic device 100.

[0228] Further, in a possible implementation, among the WUR related parameters derived by the electronic device 100, the WUR duty cycle start time t1 is different from the WUR duty cycle start time t0, the duty cycle period T3 may be the same as the duty cycle period T1, the WUR duty cycle service period T4 may be different from the WUR duty cycle service period T2, and the WUR channel offset offset2 may be the same as the WUR channel offset offset1. For example, see Fig. 9 The description in will not be repeated here.

[0229] In the application embodiment, there may be multiple devices in the Wi-Fi network, one of the multiple devices has a WUR receiver, and the main channel can be dormant. Then other devices in the multiple devices can send a wake-up frame to the device with the WUR receiver to wake up the main channel in the device. For example, Figure 5 The system 10 shown may include an electronic device 100, an electronic device 200, and an electronic device 300. The electronic device 200 in the system 10 may put the main channel into sleep mode, and then wake up the main channel after receiving a wake-up frame sent by the electronic device 100 or the electronic device 300 through the WUR receiver 105.

[0230] In one possible implementation, the electronic device 200 may have two WUR receivers (WUR receiver 1 and WUR receiver 2). The electronic device 200 may negotiate with the electronic device 100 about the WUR-related parameters of the WUR receiver 1. Then, the electronic device 100 may send a wake-up frame to the WUR receiver 1 when the WUR receiver 1 is powered on, according to the WUR-related parameters of the WUR receiver 1. The negotiation between the electronic device 200 and the electronic device 100 about the WUR-related parameters of the WUR receiver 1 in the electronic device 200 may refer to the above Figure 7 and Fig.10 The specific process of the electronic device 100 sending a wake-up frame to the WUR receiver 1 in the electronic device 200 to wake up the PCR in the electronic device 200 can be referred to Figure 6 The process of electronic device 100 waking up the PCR in electronic device 200 is shown in FIG. 1 , which will not be repeated here.

[0231] The electronic device 200 can negotiate the WUR-related parameters of the WUR receiver 2 with the electronic device 300. Then, the electronic device 300 can send a wake-up frame to the WUR receiver 2 when the WUR receiver 2 is in the power-on state according to the WUR-related parameters of the WUR receiver 2. The negotiation between the electronic device 200 and the electronic device 300 on the WUR-related parameters of the WUR receiver 2 in the electronic device 200 can refer to the above Figure 7 and Fig.10 The specific process of the electronic device 300 sending a wake-up frame to the WUR receiver 2 in the electronic device 200 to wake up the PCR in the electronic device 200 can be referred to Figure 6 The process of electronic device 100 waking up the PCR in electronic device 200 is shown in FIG. 1 , which will not be repeated here.

[0232] Preferably, in another possible implementation, the electronic device 200 has a WUR receiver, and the electronic device 200 negotiates with the electronic device 100 and the electronic device 300 on a set of WUR-related parameters of the WUR receiver. The electronic device 100 can send a wake-up frame to the WUR receiver of the electronic device 200 according to the time when the WUR receiver is in the power-on state in the WUR-related parameters negotiated between the electronic device 100 and the electronic device 200. The electronic device 300 can send a wake-up frame to the WUR receiver of the electronic device 200 according to the time when the WUR receiver is in the power-on state in the WUR-related parameters negotiated between the electronic device 300 and the electronic device 200. For details, please refer to the following description. Figure 11-Figure 15 The description in will not be repeated here.

[0233] Combine the following Figure 11-Figure 15A detailed description is given of the wake-up mechanism by which the electronic device 100 and the electronic device 300 respectively wake up the electronic device 200 when the electronic device 200 is provided with a WUR receiver.

[0234] Fig.11 The schematic diagram of the scene in which the electronic device 100 and the electronic device 300 respectively wake up the electronic device 200 is exemplarily shown. Fig.11 As shown, the electronic device 200 may be equipped with a WUR receiver and a PCR, the electronic device 100 may be equipped with a PCR, and the electronic device 300 may be equipped with a PCR. When the WUR receiver in the electronic device 200 is initially powered on, the PCR in the electronic device 200 may be in a dormant state.

[0235] Before the WUR receiver in the electronic device 200 is turned on, the electronic device 200 can negotiate WUR related parameters with the electronic device 100 and the electronic device 300 respectively. For details on how the electronic device 200 negotiates WUR related parameters with the electronic device 100 and the electronic device 300 respectively, please refer to the following description of Fig.12 and Fig.15 The description of is not repeated here.

[0236] exist Fig.11 In the example, the WUR-related parameter 1 obtained by negotiation between the electronic device 200 and the electronic device 100 is the same as the WUR-related parameter 2 obtained by negotiation between the electronic device 200 and the electronic device 300. Fig.11 As shown, WUR related parameters 1 and WUR related parameters 2 may include: WUR duty cycle start time t0, duty cycle period T1, and WUR duty cycle service period T2.

[0237] like Fig.11 As shown, when the main channel of the electronic device 200 is dormant, the specific steps of the electronic device 100 waking up the main channel of the electronic device 200 and sending data to the electronic device are as follows:

[0238] ①. The PCR of the electronic device 100 sends a wake-up frame 3 to the WUR of the electronic device 200.

[0239] When the PCR of the electronic device 100 is turned on (i.e., it becomes powered on), a wake-up frame 3 can be sent to the WUR receiver of the electronic device 200. The wake-up frame 3 is used to instruct the WUR in the electronic device 200 to wake up the PCR in the electronic device 200. The format of the wake-up frame 3 can refer to the introduction of the WUR wake-up frame in the existing protocol, which will not be repeated here.

[0240] ②. The WUR of the electronic device 200 wakes up the PCR of the electronic device 200.

[0241] After receiving the wake-up frame 3, the WUR receiver of the electronic device 200 may send a wake-up signal 3 to the PCR of the electronic device 200. The wake-up signal 3 may instruct the electronic device 200 to change the PCR from a power-off state to a power-on state, that is, instruct the electronic device 200 to power on the PCR.

[0242] ③. The PCR of electronic device 100 sends data packet 3 to the PCR of electronic device 200.

[0243] The PCR of the electronic device 100 may send data packet 3 to the PCR of the electronic device 200. The PCR in the electronic device 200 may receive the data packet 3. When the PCR in the electronic device 200 has received the data packet 3 and no longer needs to transmit data, the PCR in the electronic device 200 may enter the dormant state again.

[0244] like Fig.11 As shown, when the main channel of the electronic device 200 is dormant, the specific steps of the electronic device 300 waking up the main channel of the electronic device 200 and sending data to the electronic device are as follows:

[0245] ①. The PCR of the electronic device 300 sends a wake-up frame 4 to the WUR of the electronic device 200.

[0246] When the PCR of the electronic device 300 is turned on (i.e., it becomes powered on), a wake-up frame 4 can be sent to the WUR receiver of the electronic device 200. The wake-up frame 4 is used to instruct the WUR in the electronic device 200 to wake up the PCR in the electronic device 200. The format of the wake-up frame 4 can refer to the introduction of the WUR wake-up frame in the existing protocol, which will not be repeated here.

[0247] ②. The WUR of the electronic device 200 wakes up the PCR of the electronic device 200.

[0248] After receiving the wake-up frame 4, the WUR receiver of the electronic device 200 may send a wake-up signal 4 to the PCR of the electronic device 200. The wake-up signal 4 may instruct the electronic device 200 to change the PCR from a power-off state to a power-on state, that is, instruct the electronic device 200 to power on the PCR.

[0249] ③. The PCR of the electronic device 300 sends data packet 4 to the PCR of the electronic device 200.

[0250] The PCR of the electronic device 300 may send a data packet 4 to the PCR of the electronic device 200. The PCR in the electronic device 200 may receive the data packet 4. When the PCR in the electronic device 200 has received the data packet 4 and no longer needs to transmit data, the PCR in the electronic device 200 may enter the dormant state again.

[0251] The following will be combined Figure 12-Figure 15The process of electronic device 200 negotiating WUR related parameters with electronic device 100 and electronic device 300 respectively is described in detail.

[0252] In a possible implementation, the electronic device 200 may send a WUR mode setting request frame to the electronic device 100 and the electronic device 300, respectively, and then the electronic device 100 and the electronic device 300 reply with a WUR mode setting response frame, respectively. The electronic device 200 may send an action frame to the electronic device 100 or the electronic device 300, and the action frame may carry a modified WUR duty cycle start time, and / or a modified duty cycle period, and / or a modified WUR duty cycle service period, and / or a modified WUR channel offset.

[0253] Fig.12 The figure shows a flow chart of the electronic device 200 negotiating WUR related parameters with the electronic device 100 and the electronic device 300. Fig.12 As shown, the electronic device 200 negotiates WUR-related parameters with the electronic device 100 and the electronic device 300 respectively, which may include the following steps:

[0254] S1201. The electronic device 200 sends a WUR mode setting request frame 3 to the electronic device 100. The WUR mode setting request frame 3 carries a duty cycle field 3 and a WUR duty cycle service period field 3. The duty cycle field 3 is used to indicate that the duty cycle is T5, and the WUR duty cycle service period field 3 is used to indicate that the wake-up window length is T6.

[0255] S1202. The electronic device 100 sends a WUR mode setting response frame 3 to the electronic device 200. The WUR mode setting response frame 3 carries a WUR duty cycle start time field 3 and a WUR channel offset field 3. The WUR duty cycle start time field 3 is used to indicate that the WUR duty cycle start time is t2, and the WUR channel offset field 3 is used to indicate that the WUR channel offset is offset3.

[0256] After the electronic device 100 is associated with the electronic device 200, the electronic device 200 can negotiate with the electronic device 100 about the WUR-related parameter 1 of the WUR receiver in the electronic device 200. The electronic device 100 can send a wake-up frame to the electronic device 200 when the WUR receiver is in a powered-on state according to the WUR-related parameter 1. The WUR receiver in the electronic device 200 can also start to power on according to the WUR-related parameter 1, and listen to and receive the wake-up frame sent by the electronic device 100.

[0257] Exemplarily, as described in step S1201, the electronic device 200 may send a WUR mode setting request frame 3 to the electronic device 100. The WUR mode setting request frame 3 may carry a duty cycle field 3 and a WUR duty cycle service period field 3. Among them, the duty cycle field 3 may be used to indicate that the duty cycle is T5. The WUR duty cycle service period field 3 may be used to indicate that the wake-up window length is T6.

[0258] After the electronic device 100 receives the WUR mode setting request frame 3 sent by the electronic device 200, as described in step S1202, the electronic device 100 may reply to the electronic device 200 with a WUR mode setting response frame 3. The WUR mode setting response frame 3 may carry a WUR duty cycle start time field 3 and a WUR channel offset field 3. Among them, the WUR duty cycle start time field 3 may be used to indicate that the WUR duty cycle start time is t2. The WUR channel offset field 3 may be used to indicate that the WUR channel offset is offset3.

[0259] After the electronic device 200 and the electronic device 100 have negotiated the WUR-related parameters 1 of the WUR receiver in the electronic device 200, the WUR receiver in the electronic device 200 can start to power on at time t2, and the duration in the power-on state is T6, and the cycle of each power-on start is T5. The electronic device 100 can send a wake-up frame to the WUR receiver in the electronic device 200 starting from time t2 within the duration of T6. In this way, the electronic device 200 turns on the WUR receiver and listens for and receives the wake-up frame according to the negotiated WUR-related parameters, and the electronic device 100 sends the wake-up frame only when the WUR receiver in the electronic device 200 is in the power-on state according to the negotiated WUR-related parameters. In this way, it can be avoided that the electronic device 100 sends a wake-up frame when the WUR receiver is not turned on. In addition, the WUR receiver in the electronic device 200 can determine the channel for receiving the wake-up frame according to the WUR channel offset offset3. Moreover, the main channel in the electronic device 200 can be put into sleep mode after the parameters are negotiated, and the main channel will be awakened only after the WUR receiver receives the wake-up frame, which can save the power consumption of the electronic device 200.

[0260] Step S1201 and step S1202 may refer to the description of the above-mentioned step S701 and step S702, which will not be repeated here.

[0261] It can be understood that the duty cycle period T5 may be equal to or unequal to the duty cycle period T1. The WUR duty cycle service period T6 may be equal to or unequal to the WUR duty cycle service period T2. The WUR duty cycle start time t2 may be equal to or unequal to the WUR duty cycle start time t0. The WUR channel offset offset3 may be equal to or unequal to the WUR channel offset offset1. The embodiment of the present application does not limit the values ​​of the duty cycle period T5, the WUR duty cycle service period T6, the WUR duty cycle start time t2, and the WUR channel offset offset3.

[0262] S1203, the electronic device 200 sends a WUR mode setting request frame 4 to the electronic device 300. The WUR mode setting request frame 4 carries a duty cycle field 4 and a WUR duty cycle service period field 4. The duty cycle field 4 is used to indicate that the duty cycle is T7, and the WUR duty cycle service period field 4 is used to indicate that the wake-up window length is T8.

[0263] S1204, the electronic device 300 sends a WUR mode setting response frame 4 to the electronic device 200. The WUR mode setting response frame 4 carries a WUR duty cycle start time field 4 and a WUR channel offset field 4. The WUR duty cycle start time field 4 is used to indicate that the WUR duty cycle start time is t3, and the WUR channel offset field 4 is used to indicate that the WUR channel offset is offset4.

[0264] After the electronic device 200 is associated with the electronic device 300, the electronic device 200 can negotiate with the electronic device 300 about the WUR-related parameter 2 in the electronic device 200. The electronic device 300 can send a wake-up frame to the electronic device 200 when the WUR receiver is powered on according to the WUR-related parameter 2. The WUR receiver in the electronic device 200 can also start to power on according to the WUR-related parameter 2, and listen to and receive the wake-up frame sent by the electronic device 300.

[0265] Exemplarily, as described in step S1202, the electronic device 200 may send a WUR mode setting request frame 4 to the electronic device 300. The WUR mode setting request frame 4 may carry a duty cycle field 4 and a WUR duty cycle service period field 4. Among them, the duty cycle field 4 may be used to indicate that the duty cycle is T7. The WUR duty cycle service period field 4 may be used to indicate that the wake-up window length is T8.

[0266] After the electronic device 300 receives the WUR mode setting request frame 4 sent by the electronic device 200, as described in step S1204, the electronic device 300 may reply to the electronic device 200 with a WUR mode setting response frame 4. The WUR mode setting response frame 4 may carry a WUR duty cycle start time field 4 and a WUR channel offset field 4. Among them, the WUR duty cycle start time field 4 may be used to indicate that the WUR duty cycle start time is t4. The WUR channel offset field 4 may be used to indicate that the WUR channel offset is offset4.

[0267] After the electronic device 200 and the electronic device 100 have negotiated the WUR-related parameters 2 of the WUR receiver in the electronic device 200, the WUR receiver in the electronic device 200 can start to power on at time t3, and the duration in the power-on state is T8, and the cycle of each power-on start is T7. The electronic device 300 can send a wake-up frame to the WUR receiver in the electronic device 200 starting from time t3 within the duration of T8. In this way, the electronic device 200 turns on the WUR receiver and listens for and receives the wake-up frame according to the negotiated WUR-related parameters, and the electronic device 300 sends the wake-up frame only when the WUR receiver in the electronic device 200 is in the power-on state according to the negotiated WUR-related parameters. In this way, it can be avoided that the electronic device 300 sends a wake-up frame when the WUR receiver is not turned on. In addition, the WUR receiver in the electronic device 200 can determine the channel for receiving the wake-up frame according to the WUR channel offset offset4. Moreover, the main channel in the electronic device 200 can be put into sleep mode after the parameters are negotiated, and the main channel will be awakened only after the WUR receiver receives the wake-up frame, which can save the power consumption of the electronic device 200.

[0268] Step S1203 and step S1204 may refer to the description of the above-mentioned step S701 and step S702, which will not be repeated here.

[0269] It can be understood that the duty cycle period T7 may be equal to or unequal to the duty cycle period T1. The WUR duty cycle service period T8 may be equal to or unequal to the WUR duty cycle service period T2. The WUR duty cycle start time t3 may be equal to or unequal to the WUR duty cycle start time t0. The WUR channel offset offset4 may be equal to or unequal to the WUR channel offset offset1. The embodiment of the present application does not limit the values ​​of the duty cycle period T7, the WUR duty cycle service period T8, the WUR duty cycle start time t3, and the WUR channel offset offset4.

[0270] It is understandable that the electronic device 200 may first negotiate the WUR-related parameter 2 with the electronic device 300, and then negotiate the WUR-related parameter 1 with the electronic device 100. The embodiment of the present application does not limit the order in which the electronic device 200 negotiates the WUR-related parameter 1 with the electronic device 100, and the electronic device 200 negotiates the WUR-related parameter 2 with the electronic device 300. That is, the electronic device 200 may first execute step S1201, and then execute step S1203. Alternatively, the electronic device 200 may first execute step S1203, and then execute step S1201.

[0271] It can be understood that WUR-related parameter 1 and WUR-related parameter 2 may be the same or different.

[0272] Optionally, in a possible implementation, the electronic device 200 may change the WUR duty cycle start time and / or WUR channel offset negotiated between the electronic device 200 and the electronic device 100 through an action frame. Alternatively, the electronic device 200 may change the WUR duty cycle start time and / or WUR channel offset negotiated between the electronic device 200 and the electronic device 300 through an action frame.

[0273] S1205, the electronic device 200 sends an action frame 1 to the electronic device 300. The action frame 1 carries a WUR duty cycle start time field 5 and a WUR channel offset field 5. The WUR duty cycle start time field 5 is used to indicate that the WUR duty cycle start time is t4, and the WUR channel offset field 5 is used to indicate that the WUR channel offset is offset5.

[0274] Optionally, the electronic device 200 may perform step S1205, that is, the electronic device 200 may send an action frame 1 to the electronic device 300. The action frame 1 may carry a WUR duty cycle start time field 5 and a WUR channel offset field 5. The WUR duty cycle start time field 5 may be used to indicate that the WUR duty cycle start time is t4, and the WUR channel offset field 5 may be used to indicate that the WUR channel offset is offset5.

[0275] In one possible implementation, the electronic device 200 may carry an indication field in the WUR mode setting request frame 3 sent in step S1203, and the value of the indication field may be A1 or A2. A1 may be used to indicate that the electronic device 200 will subsequently send an action frame. A2 may be used to indicate that the electronic device 200 will not subsequently send an action frame. A1 and A2 are not equal. For example, A1 may be 1, and A2 may be 0. Alternatively, A1 may be 0, and A2 may be 1. The embodiments of the present application do not limit the specific values ​​of A1 and A2.

[0276] In one possible implementation, when the WUR duty cycle start time t2 in the WUR related parameter 1 is not equal to the WUR duty cycle start time t3 in the WUR related parameter 2, and the WUR channel offset offset3 in the WUR related parameter 1 is not equal to the WUR channel offset offset4 in the WUR related parameter 2, the electronic device 200 can modify the WUR duty cycle start time in the WUR related parameter 2 to be equal to the WUR duty cycle start time t2, and modify the WUR channel offset in the WUR related parameter 2 to be equal to the WUR channel offset offset3 in the WUR related parameter 1 through step S1205. That is, the WUR duty cycle start time t4 can be equal to the WUR duty cycle start time t2. The WUR channel offset offset5 can be equal to the WUR channel offset offset3.

[0277] Optionally, the electronic device 100 can modify the WUR duty cycle start time in the WUR related parameter 1 to be equal to the WUR duty cycle start time t3, and modify the WUR channel offset in the WUR related parameter 1 to be equal to the WUR channel offset offset4 in the WUR related parameter 2 by sending an action frame to the electronic device 200.

[0278] Exemplarily, in one possible implementation, WUR-related parameter 1 is the same as WUR-related parameter 2. For example, WUR duty cycle start time t3 or WUR duty cycle start time t4 may be the same as WUR duty cycle start time t2, that is, t3 or t4 may be equal to t2. Duty cycle period T7 may be the same as duty cycle period T5, that is, T7 may be equal to T5. WUR duty cycle service period T8 may be the same as WUR duty cycle service period T6, that is, T8 may be equal to T6. WUR channel offset offset4 or WUR channel offset offset5 may be equal to WUR channel offset offset3.

[0279] For example, Fig.13 The same schematic diagram of WUR related parameters 1 and WUR related parameters 2 is shown. Fig.13As shown, WUR related parameter 1 is the same as WUR related parameter 2. That is, the WUR receiver in the electronic device 200 can be in a powered-on state according to the WUR related parameters (WUR duty cycle start time t2, duty cycle period T5, WUR duty cycle service period T6, WUR channel offset offset3), and listen to and receive the wake-up frame sent by the electronic device 100 or the electronic device 300. The electronic device 100 and the electronic device 300 can determine the time when the WUR receiver in the electronic device 200 is in the powered-on state based on WUR related parameters such as WUR duty cycle start time t2, duty cycle period T5, WUR duty cycle service period T6, WUR channel offset offset3. The electronic device 100 or the electronic device 300 can send a wake-up frame to the electronic device 200 when the WUR receiver in the electronic device 200 is in the powered-on state.

[0280] Optionally, in another possible implementation, the WUR duty cycle start time in WUR-related parameter 1 is different from the WUR duty cycle start time in WUR-related parameter 2. The duty cycle period T5 in WUR-related parameter 1 and the duty cycle period T7 in WUR-related parameter 2 may be the same.

[0281] Furthermore, the WUR duty cycle start time in the WUR related parameter 2 may be the WUR duty cycle start time t3, or the electronic device 200 may obtain the WUR duty cycle start time t4 by modifying the action frame 1.

[0282] For example, Fig.14 FIG. 2 is a schematic diagram showing a scenario in which the electronic device 300 and the electronic device 100 start sending a wake-up frame to the electronic device 200 at different times. Fig.14 As shown, the WUR-related parameters 1 negotiated by the electronic device 200 and the electronic device 100 may include: WUR duty cycle start time t2, duty cycle period T5, WUR duty cycle service period T6. That is, the WUR receiver in the electronic device 200 can start receiving the wake-up frame sent by the electronic device 100 at a start time of t2, a listening and receiving duration of T6, and a period of T5. Fig.14 As shown, the WUR-related parameters 2 negotiated by the electronic device 200 and the electronic device 100 may include: WUR duty cycle start time t2, duty cycle period T7, WUR duty cycle service period T8. That is, the WUR receiver in the electronic device 200 can start receiving the wake-up frame sent by the electronic device 300 at a start time of t3, the listening and receiving duration is T8, and the period is T7.

[0283] like Fig.14 As shown, t2 is not equal to t3. Optionally, t3 is greater than or equal to M2, and M2 is the sum of t2 and T6.

[0284] Optionally, in a possible implementation, when t3 is less than M2, the electronic device 200 may modify the WUR time start to t4 through the above step S1205, where t4 is greater than or equal to M2.

[0285] like Fig.14 As shown, T5 is equal to T7. The sum of T6 and T8 can be equal to T5 (also equal to T7), or less than T5, which is not limited here. T6 and T8 can be equal or unequal, and the size of T6 and T8 is not limited here.

[0286] In this way, the time when the electronic device 100 sends the wake-up frame to the electronic device 200 can be staggered with the time when the electronic device 300 sends the wake-up frame to the electronic device 200. This can reduce the conflict of the electronic device 100 and the electronic device 300 sending data to the electronic device 200 at the same time, and can stagger the traffic.

[0287] Optionally, in another possible implementation, when the electronic device 200 negotiates WUR-related parameters of the WUR receiver in the electronic device 200 with the electronic device 100 or the electronic device 300, the electronic device 200 may specify parameters such as the WUR duty cycle start time, WUR duty cycle service period, duty cycle, and WUR channel offset of the WUR receiver in the electronic device 200 through an action frame or a modified WUR mode setting request frame.

[0288] Fig.15 Another flow chart of the electronic device 200 negotiating WUR related parameters with the electronic device 100 and the electronic device 300 is shown as an example. Fig.15 As shown, the electronic device 200 negotiates WUR-related parameters with the electronic device 100 and the electronic device 300 respectively, which may include the following steps:

[0289] S1501. The electronic device 200 sends an action frame 3 to the electronic device 100. The action frame 3 carries a duty cycle field 6, a WUR duty cycle service period field 6, a WUR duty cycle start time field 6, and a WUR channel offset field 6.

[0290] S1502 , the electronic device 100 sends a response 1 to the electronic device 200 .

[0291] After the electronic device 100 is associated with the electronic device 200, the electronic device 200 can negotiate with the electronic device 100 about the WUR-related parameter 1 of the WUR receiver in the electronic device 200. The electronic device 100 can send a wake-up frame to the electronic device 200 when the WUR receiver is in a powered-on state according to the WUR-related parameter 1. The WUR receiver in the electronic device 200 can also start to power on according to the WUR-related parameter 1, and listen to and receive the wake-up frame sent by the electronic device 100.

[0292] Exemplarily, as shown in step S1501, the electronic device 200 may send an action frame 3 to the electronic device 100. The action frame 3 may carry a duty cycle field 6, a WUR duty cycle service period 6, a WUR duty cycle start time field 6, and a WUR channel offset field 6. The duty cycle field 6 may be used to indicate the value of the period for the WUR receiver in the electronic device 200 to listen to and receive the wake-up frame of the electronic device 100. The WUR duty cycle service period 6 may be used to indicate the value of the duration of each period for the WUR receiver in the electronic device 200 to listen to and receive the wake-up frame of the electronic device 100. The WUR duty cycle start time field 6 may be used to indicate or suggest the value of the start time for the WUR receiver in the electronic device 200 to listen to and receive the wake-up frame of the electronic device 100. The WUR channel offset field 6 may be used to indicate or suggest the channel offset for the WUR receiver in the electronic device 200 to listen to and the wake-up frame of the electronic device 100.

[0293] Optionally, the period for the WUR receiver in the electronic device 200 to listen to and receive the wake-up frame of the electronic device 100 may be T5. The duration for each period for the WUR receiver in the electronic device 200 to listen to and receive the wake-up frame of the electronic device 100 may be T6. The start time for the WUR receiver in the electronic device 200 to listen to and receive the wake-up frame of the electronic device 100 may be t2. The channel offset for the WUR receiver in the electronic device 200 to listen to and receive the wake-up frame of the electronic device 100 may be offset3. The embodiment of the present application does not limit the specific values ​​of the period for the WUR receiver in the electronic device 200 to listen to and receive the wake-up frame of the electronic device 100, the duration for each period for the WUR receiver in the electronic device 200 to listen to and receive the wake-up frame of the electronic device 100, the start time for the WUR receiver in the electronic device 200 to listen to and receive the wake-up frame of the electronic device 100, and the channel offset for the WUR receiver in the electronic device 200 to listen to and receive the wake-up frame of the electronic device 100.

[0294] After receiving the action frame 3 , the electronic device 100 may reply with a response 1 .

[0295] In one possible implementation, when the WUR duty cycle start time field 6 and the WUR channel offset field 6 in the action frame 3 are respectively used to indicate the start time of the WUR receiver in the electronic device 200 to listen to and receive the wake-up frame of the electronic device 100 and the channel offset for indicating the WUR receiver in the electronic device 200 to listen to and receive the wake-up frame of the electronic device 100, the response 1 can be an acknowledgment message (ACK).

[0296] Optionally, in another possible implementation, when the WUR duty cycle start time field 6 and the WUR channel offset field 6 in the action frame 3 are respectively used to suggest the WUR receiver in the electronic device 200 to listen to and receive the start time of the wake-up frame of the electronic device 100 and the value of the channel offset for suggesting the WUR receiver in the electronic device 200 to listen to and receive the wake-up frame of the electronic device 100, the response 1 can also be an action frame, and the action frame can carry the WUR duty cycle start time field 8 and the WUR channel offset field 8. The WUR duty cycle start time field 8 can be used to indicate the start time of the WUR receiver in the electronic device 200 to listen to and receive the wake-up frame of the electronic device 100. The WUR channel offset field 8 can be used to indicate the channel offset for the WUR receiver in the electronic device 200 to listen to and receive the wake-up frame of the electronic device 100. The WUR duty cycle start time indicated in the WUR duty cycle start time field 8 can be the same as the WUR duty cycle start time suggested in the WUR start field 6. The WUR channel offset indicated in WUR channel offset field 8 may be the same as the WUR channel offset indicated in WUR channel offset field 6.

[0297] Optionally, in a possible implementation, the electronic device 200 sends a WUR mode setting request frame 5 to the electronic device 100. Compared with the WUR mode setting request frame in the existing protocol, the WUR mode setting request frame 5 includes not only the duty cycle field 9 and the WUR duty cycle service period field 9 specified in the existing protocol, but also includes a customized WUR start field 9 and a WUR channel offset field 9. The duty cycle field 9 can be used to indicate the value of the period in which the WUR receiver in the electronic device 200 listens to and receives the wake-up frame of the electronic device 100. The WUR duty cycle service period 9 can be used to indicate the value of the duration of each period in which the WUR receiver in the electronic device 200 listens to and receives the wake-up frame of the electronic device 100. The WUR duty cycle start time field 9 can be used to indicate or suggest the value of the start time for the WUR receiver in the electronic device 200 to listen to and receive the wake-up frame of the electronic device 100. The WUR channel offset field 9 can be used to indicate or suggest the value of the channel offset for the WUR receiver in the electronic device 200 to listen to and receive the wake-up frame of the electronic device 100.

[0298] When the electronic device 100 receives the WUR mode setting request frame 5, it can reply with a response 1.

[0299] In one possible implementation, when the WUR duty cycle start time field 9 and the WUR channel offset field 9 in the WUR mode setting request frame 5 are respectively used to indicate the start time of the WUR receiver in the electronic device 200 listening and receiving the wake-up frame of the electronic device 100 and the channel offset for indicating the WUR receiver in the electronic device 200 listening and the wake-up frame of the electronic device 100, the response 1 can be an acknowledgment message (ACK).

[0300] Optionally, in another possible implementation, when the WUR duty cycle start time field 9 and the WUR channel offset field 9 in the WUR mode setting request frame 5 are respectively used to suggest the WUR receiver in the electronic device 200 to listen to and receive the start time of the wake-up frame of the electronic device 100 and the value of the channel offset for suggesting the WUR receiver in the electronic device 200 to listen to and receive the wake-up frame of the electronic device 100, the response 1 may also be a WUR mode setting response frame 5, and the WUR mode setting response frame 5 may carry the WUR duty cycle start time field 10 and the WUR channel offset field 10. The WUR duty cycle start time field 10 may be used to indicate the start time for the WUR receiver in the electronic device 200 to listen to and receive the wake-up frame of the electronic device 100. The WUR channel offset field 10 may be used to indicate the channel offset for the WUR receiver in the electronic device 200 to listen to and receive the wake-up frame of the electronic device 100. The WUR duty cycle start time indicated in the WUR duty cycle start time field 10 may be the same as the WUR duty cycle start time suggested in the WUR start field 9. The WUR channel offset indicated in the WUR channel offset field 10 may be the same as the WUR channel offset indicated in the WUR channel offset field 9.

[0301] S1503, the electronic device 200 sends an action frame 4 to the electronic device 300, the action frame 4 carries the duty cycle field 7, the WUR duty cycle service period field 7, the WUR duty cycle start time field 7, and the WUR channel offset field 7.

[0302] S1504 , the electronic device 300 sends a response 2 to the electronic device 200 .

[0303] After the electronic device 300 is associated with the electronic device 200, the electronic device 200 can negotiate with the electronic device 300 about the WUR-related parameter 2 of the WUR receiver in the electronic device 200. The electronic device 300 can send a wake-up frame to the electronic device 200 when the WUR receiver is in a powered-on state according to the WUR-related parameter 2. The WUR receiver in the electronic device 200 can also start to power on according to the WUR-related parameter 2, and listen to and receive the wake-up frame sent by the electronic device 300.

[0304] Exemplarily, as shown in step S1503, the electronic device 200 may send an action frame 4 to the electronic device 300. The action frame 4 may carry a duty cycle field 7, a WUR duty cycle service period 7, a WUR duty cycle start time field 7, and a WUR channel offset field 7. The duty cycle field 7 may be used to indicate the value of the period for the WUR receiver in the electronic device 200 to listen to and receive the wake-up frame of the electronic device 100.
