[0049] The following will describe the technical solutions in the embodiments of this application in conjunction with the drawings in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of the embodiments. With respect to the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0050] The technical solutions of the embodiments of the present application can be applied to various communication systems, such as Wireless Local Area Networks (WLAN), Wireless Fidelity (WiFi), or other communication systems.

[0051] Please refer to Figure 1, which shows a schematic diagram of a wireless communication system provided by an embodiment of the present application. As shown in Figure 1, the wireless communication system may include: an access point (AP) and a station (STA).

[0052] In some scenarios, an AP can be referred to as an AP STA, meaning that in a sense, an AP is also a type of STA. In some scenarios, a STA can be referred to as a non-AP STA.

[0053] In some embodiments, STAs may include AP STAs and non-AP STAs. Communication in a communication system may be between an AP and a non-AP STA, between a non-AP STA and a non-AP STA, or between a STA and a peer STA. A peer STA may refer to a device that communicates with a STA. For example, a peer STA may be an AP or a non-AP STA.

[0054] An AP acts as a bridge between wired and wireless networks, connecting wireless network clients together and then connecting the wireless network to the Ethernet. An AP can be a terminal device (such as a mobile phone) or a network device (such as a router) equipped with a Wireless Fidelity (Wi-Fi) chip.

[0055] It should be understood that the role of STA in the communication system is not absolute. For example, in some scenarios, when a mobile phone is connected to a router, the mobile phone is a non-AP STA. When the mobile phone serves as a hotspot for other mobile phones, the mobile phone plays the role of AP.

[0056] APs and non-AP STAs can be devices used in the Internet of Vehicles, IoT nodes and sensors in the Internet of Things (IoT), smart cameras, smart remote controls, smart water and electricity meters in smart homes, and sensors in smart cities.

[0057] In some embodiments, a non-AP STA may support 802.11be. A non-AP STA may also support various current and future 802.11 family wireless LAN standards, such as 802.11ax, 802.11ac, 802.11n, 802.11g, 802.11b, and 802.11a.

[0058] In some embodiments, the AP may be a device supporting the 802.11be standard. The AP may also be a device supporting various current and future 802.11 family WLAN standards, such as 802.11ax, 802.11ac, 802.11n, 802.11g, 802.11b, and 802.11a.

[0059] In the embodiment of the present application, the STA may be a mobile phone, tablet computer, computer, virtual reality (VR) device, augmented reality (AR) device, wireless device in industrial control, set-top box, wireless device in self-driving, in-vehicle communication equipment, wireless device in remote medical, wireless device in smart grid, wireless device in transportation safety, wireless device in smart city, wireless device in smart home, wireless communication chip, ASIC (Application Specific Integrated Circuit), SOC (System on Chip), etc. that supports WLAN / WIFI technology.

[0060] The frequency bands supported by WLAN technology may include but are not limited to: low frequency bands (2.4 GHz, 5 GHz, 6 GHz) and high frequency bands (45 GHz, 60 GHz).

[0061] There are one or more links between the station and the access point. In some embodiments, the station and the access point support multi-band communication. For example, communication is performed simultaneously on the 2.4 GHz, 5 GHz, 6 GHz, 45 GHz, and 60 GHz frequency bands, or communication is performed simultaneously on different channels of the same frequency band (or different frequency bands), thereby improving the communication throughput and / or reliability between devices. Such a device is generally referred to as a multi-band device, or a multi-link device (MLD), sometimes also referred to as a multi-link entity or a multi-band entity. A multi-link device can be an access point device or a station device. If the multi-link device is an access point device, the multi-link device includes one or more APs; if the multi-link device is a station device, the multi-link device includes one or more non-AP STAs.

[0062] A multi-link device including one or more APs may be referred to as an AP MLD, and a multi-link device including one or more non-AP STAs may be referred to as a Non-AP MLD.

[0063] In an embodiment of the present application, the AP may include multiple APs, the Non-AP may include multiple STAs, multiple links may be formed between the APs in the AP and the STAs in the Non-AP, and data communication may be performed between the APs in the AP and the corresponding STAs in the Non-AP through the corresponding links.

[0064] An AP is a device deployed in a wireless local area network to provide wireless communication capabilities for STAs. A station may include: User Equipment (UE), an access terminal, a subscriber unit, a subscriber station, a mobile station, a mobile station, a remote station, a remote terminal, a mobile device, a wireless communication device, a user agent, or a user device. Optionally, a station may also be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with wireless communication capabilities, a computing device or other processing device connected to a wireless modem, a vehicle-mounted device, or a wearable device, but the embodiments of the present application are not limited thereto.

[0065] Optionally, both the station and the access point support the IEEE 802.11 standard.

[0066] It should be understood that the terms "system" and "network" are often used interchangeably herein. The term "and / or" is simply a description of an association between related objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " generally indicates that the related objects are in an "or" relationship.

[0067] The terms used in the embodiments of this application are intended only to explain the specific embodiments of this application and are not intended to limit this application. The terms "first," "second," "third," and "fourth," etc. in the specification and claims of this application and the accompanying drawings are used to distinguish different objects, not to describe a specific order. In addition, the terms "including" and "having," and any variations thereof, are intended to cover non-exclusive inclusions.

[0068] It should be understood that the "indication" mentioned in the embodiments of this application can be a direct indication, an indirect indication, or an indication of an association. For example, "A indicates B" can mean that A directly indicates B, for example, B can be obtained through A; it can also mean that A indirectly indicates B, for example, A indicates C, and B can be obtained through C; it can also mean that there is an association between A and B.

[0069] In the description of the embodiments of the present application, the term "corresponding" may indicate a direct or indirect correspondence between the two, or an association relationship between the two, or a relationship between indication and being indicated, configuration and being configured, etc.

[0070] In the embodiments of the present application, "pre-definition" or "pre-configuration" may be implemented by pre-storing corresponding codes, tables, or other methods that can be used to indicate relevant information in a device (e.g., a terminal device and a network device). The present application does not limit the specific implementation method. For example, pre-definition may refer to information defined in a protocol.

[0071] In the embodiments of the present application, the “protocol” may refer to a standard protocol in the communications field, for example, it may be an evolution of an existing LTE protocol, NR protocol, Wi-Fi protocol, or a protocol related to other communication systems. The present application does not limit the protocol type.

[0072] As 5G industry applications expand, the types of connected objects and application scenarios will increase, placing higher demands on the price and power consumption of communication terminals. The application of battery-free, low-cost passive IoT devices has become a key technology for cellular IoT, expanding the types and number of terminals connected to 5G networks and truly realizing the Internet of Everything. Passive IoT devices can be based on existing zero-power devices, such as radio frequency identification (RFID) technology, and can be extended to suit cellular IoT.

[0073] In order to facilitate a better understanding of the embodiments of the present application, the classification of zero-power devices related to the present application is explained.

[0074] Optionally, based on the energy source and usage of the zero-power device, the zero-power device can be divided into a passive zero-power device, a semi-passive zero-power device and an active zero-power device.

[0075] 1) Passive zero-power devices

[0076] Zero-power devices do not require internal batteries. When they approach network devices (such as the reader / writer of a radio frequency identification (RFID) system), they are within the near field formed by the radiation from the network device's antenna. Therefore, the zero-power device antenna generates an induced current through electromagnetic induction, which drives the low-power chip circuit of the zero-power device. This implements tasks such as demodulating the forward link signal (downlink, the link from the network device to the zero-power device) and modulating the backward link signal (uplink, the link from the zero-power device to the network device). For backscatter links, the zero-power device uses backscattering to transmit signals.

[0077] It can be seen that the passive zero-power device does not require a built-in battery to drive either the forward link or the reverse link, and is a truly zero-power device.

[0078] Passive zero-power devices do not require batteries, and their RF and baseband circuits are very simple. For example, they do not require a low-noise amplifier (LNA), a power amplifier (PA), a crystal oscillator, or an analog-to-digital conversion (ADC). Therefore, they have many advantages such as small size, light weight, very low price, and long service life.

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

[0080] Semi-passive zero-power devices do not have conventional batteries themselves, but instead use radio frequency (RF) energy harvesting modules to harvest radio wave energy, or solar / light / thermal / kinetic energy harvesting modules to harvest energy, and store the harvested energy in an energy storage unit (such as a capacitor). Once the energy storage unit harvests energy, it drives the low-power chip circuitry of the zero-power device, performing tasks such as demodulating forward link signals and modulating backward link signals. For backscatter links, the zero-power device uses backscattering to transmit signals.

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

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

[0083] 3) Active zero-power devices

[0084] The zero-power devices used in some scenarios can also be active zero-power devices. Such terminals can have built-in batteries (conventional batteries, such as dry batteries, rechargeable lithium batteries, etc.). The battery is used to drive the low-power chip circuit of the zero-power device. It realizes the demodulation of the forward link signal and the modulation of the reverse link signal. However, for the backscatter link, the zero-power device uses the backscatter implementation method to transmit the signal. Therefore, the zero power consumption of this type of terminal is mainly reflected in the fact that the signal transmission of the reverse link does not require the terminal's own power, but uses the backscatter method. Although the active zero-power device uses a battery, due to the sampling of ultra-low power communication technology, the power consumption is very low, so compared with the existing technology, the battery life can be greatly improved.

[0085] Active zero-power devices, with built-in batteries to power the RFID chip, increase the tag's read and write distance and improve communication reliability. Therefore, they are suitable for scenarios with relatively high requirements for communication distance and read latency.

[0086] To facilitate a better understanding of the embodiments of the present application, the environmental energy-based devices related to the present application are described.

[0087] In NR and Wi-Fi systems, the battery-free and low-cost nature of devices enables low-cost, large-scale deployment and maintenance-free development of IoT devices. Current standards are exploring how to support ambient energy-based IoT devices in NR and Wi-Fi systems. These devices, known as ambient IoT (AMP IoT) devices, draw their operating energy from harvested ambient energy sources, such as wireless signals, solar energy, and thermal energy. These devices are similar to passive or semi-passive devices in zero-power communications.

[0088] To facilitate a better understanding of the embodiments of the present application, the physical layer protocol data unit (PPDU) related to the present application is explained.

[0089] Wi-Fi device information is transmitted based on PPDU frames. A PPDU frame consists of a physical layer header and data. For example, the 802.11a / g physical layer header begins with three parts: a short training field (STF), a long training field (LTF), and a signal (SIGNAL). These two parts, along with the data portion, are shown in Figure 2. The first part, the STF, consists of 10 short symbols (t1-t10), each 0.8µs long. These symbols perform a variety of functions, primarily implementing frame synchronization and coarse frequency synchronization. t1-t7 primarily encompass signal detection, automatic gain control (AGC), and diversity selection, while t8-t10 primarily encompass coarse frequency, offset estimation, and timing synchronization. The second part is the LTF, which implements fine frequency synchronization and channel estimation. The SIGNAL part carries information related to the data portion, including the data transmission rate, packet length, reserved bits, and tail bits. The data portion of the PPDU carries the Media Access Control (MAC) frame. The MAC frame format consists of the following parts: MAC header, frame body, and frame check sequence (FCS), as shown in Figure 3.

[0090] To facilitate a better understanding of the embodiments of the present application, a wake-up receiver (WUR) related to the present application is described.

[0091] In the 802.11ba technology, the WUR STA device has a wake-up receiver (WUR) for receiving wake-up signals. The wake-up receiver has the characteristics of extremely low cost, extremely low complexity and extremely low power consumption. It mainly receives the wake-up signal through envelope detection. When the WUR STA is in sleep state, its main receiver can be turned off to save power, while the WUR is in the on state to receive the wake-up signal sent by the AP. If the AP needs to transmit data with the STA, it can use the wake-up signal to wake up the STA and turn on the main receiver. Otherwise, the UE's main receiver can be in the off state.

[0092] In a WiFi system, if a STA device is not associated with an AP, it needs to perform active scanning to discover surrounding APs and select a suitable AP to initiate the association process. If a STA is already associated with an AP, it may move out of the coverage area of ​​the AP and therefore needs to perform a scanning process to discover new APs. Typically, a STA will scan on multiple channels, searching for beacon frames sent by the AP or actively sending probe request frames and waiting for probe response frames sent by the AP. This scanning process increases the STA's power consumption and latency. To reduce the power consumption and latency of scanning, a WUR STA can perform scanning through the WUR, especially when the WUR STA is in sleep mode and the main receiver is turned off. In 802.11ba technology, a WUR AP can send a WUR discovery frame to indicate the AP's compressed Service Set Identifier (SSID) and the primary channel of the AP's corresponding Basic Service Set (BSS). WUR STA receives WUR discovery frame through WUR and obtains BSS information of nearby APs, thereby reducing the power consumption and delay of the WUR STA's main receiver for scanning.

[0093] In 802.11ba technology, although the WUR of a WUR STA has extremely low power consumption compared to the main receiver, it is still an active device and its energy supply is not limited. For AMP STAs, their energy source is unstable and their energy storage capacity is also significantly limited, so they have more stringent requirements for energy use. Especially in their initial operation phase, without energy, subsequent processes such as scanning BSS and association are impossible. Therefore, when an AMP STA is out of power, the first thing it needs to solve is to obtain energy. Although wireless signals in space are relatively abundant, they are not stable. A reliable method is for an AP or a dedicated power supply node to provide energy to AMP STAs within its coverage area.

[0094] In order to facilitate a better understanding of the embodiments of the present application, the problems solved by the present application are explained.

[0095] IoT devices powered by ambient energy primarily draw their energy from the environment, such as radio frequency signals. When communicating with the network, devices must first collect sufficient ambient energy to support subsequent processes such as synchronization and access. Currently, there is no stable source of ambient energy, such as radio frequency signals, to power these communication processes. This makes stable and reliable operation of IoT devices based on ambient energy difficult to achieve. Furthermore, it's currently difficult to detect ambient energy devices.

[0096] Based on the above problems, the present application proposes a solution for discovering environmental energy sites, in which the environmental energy sites receive discovery signals on at least one preset channel, avoiding the blind detection of discovery signals by the environmental energy sites on all channels, reducing the delay in detecting discovery signals, and reducing the energy consumed by the environmental energy sites due to detecting discovery signals, thereby ensuring the communication accessibility of the environmental energy sites. Alternatively, the present application proposes a solution for supplying energy to environmental energy sites, in which the environmental energy sites receive power supply signals on at least one preset channel, avoiding the blind detection of power supply signals by the environmental energy sites on all channels, thereby providing energy to the environmental energy sites more stably and efficiently, ensuring the communication accessibility of the environmental energy sites.

[0097] To facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific embodiments. The following related technologies can be combined with the technical solutions of the embodiments of the present application as optional solutions, and they all fall within the scope of protection of the embodiments of the present application. The embodiments of the present application include at least part of the following contents.

[0098] FIG4 is a schematic flowchart of a wireless communication method 200 according to an embodiment of the present application. As shown in FIG4 , the wireless communication method 200 may include at least part of the following contents:

[0099] S210, the environment-capable access point sends a discovery signal on at least one preset channel;

[0100] S220: The environment-capable station receives a discovery signal on at least one preset channel.

[0101] In an embodiment of the present application, the environmental energy site receives a discovery signal on at least one preset channel, so that the environmental energy access point can discover the environmental energy site, avoiding the environmental energy site from blindly detecting the discovery signal on all channels, reducing the delay in detecting the discovery signal, and reducing the energy consumed by the environmental energy site due to detecting the discovery signal, thereby ensuring the communication reachability of the environmental energy site.

[0102] In an embodiment of the present application, the environmental energy site obtains the energy required for communication by collecting environmental energy (such as light energy, thermal energy, wind energy, radio frequency energy, mechanical energy, kinetic energy, etc.), and can support backscattering communication mode and active transmission communication mode.

[0103] In the embodiments of the present application, an ambient power site may also be referred to as an "Ambient power enabled IoT device" or "Ambient IoT device." Specifically, an ambient power IoT device refers to an IoT device that uses various ambient energies, such as radio frequency energy, light energy, solar energy, thermal energy, mechanical energy, and the like. An ambient IoT device may have no energy storage capability or may have very limited energy storage capability (e.g., using a capacitor with a capacity of tens of microfarads).

[0104] In an embodiment of the present application, an ambient energy access point (AMP AP) can be a device that communicates with an ambient energy station (AMP STA). It can be a conventional access point (AP) or, like an ambient energy station, obtain the energy required for communication by collecting ambient energy (such as light energy, thermal energy, wind energy, radio frequency energy, mechanical energy, kinetic energy, etc.).

[0105] In some embodiments, ambient energy stations can also be zero-power devices, featuring features such as battery-free and maintenance-free operation. Specifically, zero-power devices have a simple structure, low complexity, and low cost. They can support energy harvesting from ambient energy (e.g., light, heat, radio frequency, mechanical, kinetic, etc.) to obtain the energy required for communication. They can support backscatter communication and, for some zero-power devices, active transmission communication.

[0106] In some embodiments, in the above S220, the ambient energy station receives the discovery signal on the at least one channel before associating with the ambient energy access point. That is, before the ambient energy station associates with the ambient energy access point, the ambient energy station receives the discovery signal on at least one preset channel, thereby avoiding the ambient energy station blindly detecting the discovery signal on all channels, reducing the delay in detecting the discovery signal, and reducing the energy consumed by the ambient energy station due to detecting the discovery signal, thereby ensuring the communication reachability of the ambient energy station.

[0107] In some embodiments, the discovery signal received on the at least one channel carries at least one of the following:

[0108] The SSID of the ambient access point and the primary channel information of the BSS corresponding to the ambient access point.

[0109] For example, the SSID of the environment access point carried by the discovery signal received on the at least one channel may be a compressed SSID.

[0110] That is, in this embodiment, the ambient access point can carry the compressed SSID of the ambient access point and the primary channel information of the BSS corresponding to the ambient access point in the discovery signal. The ambient access point scans for discovery signals on at least one preset channel. When obtaining the discovery signal, it also obtains the compressed SSID of the ambient access point and the primary channel information of the BSS corresponding to the ambient access point. This avoids the ambient access point from directly scanning all channels, reduces the delay in detecting the discovery signal, and reduces the energy consumed by the ambient access point due to detecting the discovery signal.

[0111] In some embodiments, the discovery signal received on the at least one channel carries transmission parameters of a beacon frame of the environment access point.

[0112] In some embodiments, the discovery signal received on the at least one channel carries at least one of the following:

[0113] The SSID of the ambient access point, the primary channel information of the BSS corresponding to the ambient access point, and the transmission parameters of the beacon frame of the ambient access point.

[0114] In some embodiments, the transmission parameters of the beacon frame of the environment-capable access point include but are not limited to at least one of the following: beacon interval, target beacon transmission times (TBTT), and time domain offset information between the discovery signal carrying the transmission parameters of the beacon frame of the environment-capable access point and the TBTT (such as the most recent TBTT).

[0115] That is, in this embodiment, the ambient energy access point can carry the transmission parameters of the beacon frame of the ambient energy access point on the discovery signal, so that the ambient energy station can detect the beacon frame of the ambient energy access point based on the transmission parameters of the beacon frame of the ambient energy access point, thereby reducing the delay in detecting the beacon frame and reducing the energy consumed by the ambient energy station due to detecting the beacon frame.

[0116] In some embodiments, the ambient energy station obtains energy through the discovery signal received on the at least one channel. That is, in this embodiment, the discovery signal can also provide energy to the ambient energy station, which can solve the energy supply problem of the ambient energy station and avoid the ambient energy station blindly detecting the energy supply signal on all channels, thereby providing energy to the ambient energy station more stably and efficiently.

[0117] For example, for ambient energy sites to operate, the ambient energy access point needs to provide a basic energy supply signal. For example, the ambient energy access point sends a discovery signal on at least one preset channel. When the ambient energy site is out of power, it preferentially obtains energy through the discovery signal on the at least one channel to carry out subsequent operations. This prevents the ambient energy site from scanning for energy supply signals when there is no energy storage or the energy storage is very low.

[0118] In some embodiments, the at least one channel belongs to one or more frequency bands. Specifically, for example, the at least one preset channel includes a specific channel in a specific frequency band, such as channel 1 in the 2.4 GHz band, or channels 40, 44, 149, and 153 in the 5 GHz band, and also includes channels in frequency bands below 1 GHz. Before an ambient energy station is associated with an ambient energy access point, it can obtain energy through the at least one preset channel.

[0119] In some embodiments, the frequency band to which the at least one channel belongs is agreed upon by a protocol, and / or the frequency domain resources for the environment-capable station to receive the discovery signal within the at least one channel are agreed upon by a protocol.

[0120] For example, the frequency domain resources for receiving discovery signals in at least one channel of an ambient energy station can be part of the bandwidth of a 20MHz channel in the 2.4GHz band. The center frequencies of the 14 partially overlapping channels in the 2.4GHz band can be as shown in Table 1, with the center frequencies of different channels spaced 5MHz apart. The effective bandwidth of each channel is 20MHz, with an additional 2MHz as isolation bandwidth. For example, for an ambient energy station, when out of power, it is necessary to obtain a discovery signal on channel 1 in the 2.4GHz band in order to perform corresponding energy storage and then carry out subsequent work.

[0121] Table 1

[0122] In some embodiments, the discovery signal received by the environment-capable station on the at least one channel carries first indication information;

[0123] In which, the first indication information is used to indicate the information of the channel where the power supply signal of the environmental energy site is located (such as the channel number or channel index), or the first indication information is used to indicate the information of the channel set where the power supply signal of the environmental energy site is located (such as the channel set number or channel set index), or the first indication information is used to indicate the information of the frequency band where the power supply signal of the environmental energy site is located (such as the frequency band number or frequency band index).

[0124] For example, after obtaining energy storage through a discovery signal received on at least one preset channel, the channel (channel) or frequency band where other energy supply signals are located can be directly obtained. For example, the first indication information can be directly carried on the discovery signal, which can indicate the channel number or frequency band number of other energy supply. Specifically, after obtaining the first indication information, the environmental energy station can tune (retuning) to the corresponding channel or frequency band to obtain energy. Specifically, the first indication information can also indicate a channel set (i.e., a first channel set), which contains multiple channels. After obtaining energy storage through a discovery signal received on at least one preset channel, the environmental energy station can scan on the channel or frequency band indicated by the first indication information to obtain other energy supply signals. For example, the discovery signal received on a preset channel on channel 1 of the 2.4GHz frequency band carries the first indication information, and the first indication information can indicate that the channel set (i.e., the first channel set) where other energy supply signals are located includes channel 6, channel 7, and channel 8.

[0125] In some embodiments, when the first indication information is used to indicate information about the channel where the power supply signal of the environmental energy site is located, the channel where the power supply signal of the environmental energy site is located is the same as the channel through which the environmental energy site performs communication.

[0126] In some embodiments, when the first indication information is used to indicate information of a channel set where the power supply signal of the environmental energy site is located, the channel set where the power supply signal of the environmental energy site is located includes a channel on which the environmental energy site performs communication.

[0127] In some embodiments, when the first indication information is used to indicate the frequency band of the power supply signal of the environmental energy site, the frequency band of the power supply signal of the environmental energy site is the same as the frequency band in which the environmental energy site performs communication.

[0128] Specifically, in order to avoid the AMP STA from constantly retuning between the energy collection and communication channels, preferably, the energy supply signal and the communication-related channel are on the same channel or on the same frequency band.

[0129] In some embodiments, the energy supply signal received by the environmental energy station based on the first indication information carries second indication information; wherein,

[0130] The second indication information is used to indicate the channel number of the primary channel of the target BSS, and / or, the second indication information is used to indicate the frequency band number where the primary channel of the target BSS is located; or,

[0131] The second indication information is used to indicate the number of a channel in the channel set of the target BSS, and / or the second indication information is used to indicate the number of a frequency band where the channel in the channel set of the target BSS is located.

[0132] In some embodiments, the discovery signal received by the environment-capable station on the at least one channel carries second indication information; wherein,

[0133] The second indication information is used to indicate the channel number of the primary channel of the target BSS, and / or, the second indication information is used to indicate the frequency band number where the primary channel of the target BSS is located; or,

[0134] The second indication information is used to indicate the number of a channel in the channel set of the target BSS, and / or the second indication information is used to indicate the number of a frequency band where the channel in the channel set of the target BSS is located.

[0135] Optionally, the primary channel of the target BSS is a channel through which beacon frames of the target BSS are sent.

[0136] In some embodiments, the second indication information is further used to indicate identification information of the target BSS.

[0137] In some embodiments, the primary channel of the target BSS is used for the environment-capable station to receive beacon frames, and / or, the primary channel of the target BSS is used for the environment-capable station to send probe request frames, and / or, the primary channel of the target BSS is used for the environment-capable station to receive probe response frames.

[0138] Optionally, the beacon frame may be an AMP beacon frame, which may be a dedicated beacon frame for an AMP STA.

[0139] Optionally, the probe request frame may be an AMP probe request frame, which may be a dedicated probe request frame for an AMP STA. Optionally, the probe response frame may be an AMP response request frame, which may be a dedicated response request frame for an AMP STA.

[0140] Specifically, the AMP STA can obtain the channel number of the main channel of the target BSS or the channel number in the channel set of the target BSS while obtaining power, thereby reducing the power consumption and delay of the subsequent AMP STA scanning on multiple channels to determine the primary channel of the target BSS. The AMP STA can receive the AMP beacon frame, or send the probe request frame and receive the probe response frame on the channel indicated by the second indication information. For example, the power supply signal received on channel 1 in the 2.4GHz frequency band carries the second indication information, indicating that the primary channel of the target BSS is channel 6. In addition to indicating the primary channel of the target BSS, the information carried in the power supply signal can also indicate the ID information of the target BSS.

[0141] In some embodiments, the waveform of the energy supply signal is generally a continuous wave (CW). The energy supply signal can carry information (such as second indication information) by amplitude modulation (such as On-Off Keying (OOK) modulation). As shown in Figure 5, OOK modulation is performed in the energy supply signal to carry information 101010 as the second indication information. The energy supply signal can be used as a periodic signal to repeatedly send energy supply information. The energy supply signal can be sent in a certain frame structure, which includes a part that carries information and a part that does not carry information. Among them, the energy supply efficiency of the part that does not carry information is higher than that of the part that carries information.

[0142] In some embodiments, the beacon frame or probe response frame received by the ambient energy station on the main channel of the target BSS carries first power supply information; wherein, the first power supply information is used to indicate the channel and / or frequency band in which the ambient energy station receives the power supply signal after associating with the target BSS.

[0143] In some embodiments, the beacon frame or probe response frame received by the ambient energy station on the primary channel of the target BSS includes a radio frequency energy source information element, wherein the radio frequency energy source information element includes an operating class field and a channel field, the operating class field is used to indicate the frequency band in which the ambient energy station receives the power supply signal after associating with the target BSS, and the channel field is used to indicate the channel in which the ambient energy station receives the power supply signal after associating with the target BSS. For example, the radio frequency energy source information element may be as shown in FIG6.

[0144] For example, when the AMP STA receives the AMP beacon frame on the primary channel through the collected energy scan, it can obtain the parameters of the target BSS and carry out the subsequent association process. The AMP beacon frame can carry information related to the power supply signal, such as the frequency band and channel, so that the AMP STA can obtain power on the corresponding channel and communicate on the same or different channels. The power supply signal here is a power supply signal specific to the target BSS, which is used as the power supply signal required for the AMP STA to work in the target BSS. The frequency band and channel mentioned above can be indicated by the operating class and channel information. Among them, the operating class is an index number, which corresponds to a set of channel frequency ranges, channel bandwidths, channel center frequencies and specification requirements that need to be met.

[0145] In some embodiments, after the ambient-capable station associates with the ambient-capable access point, the ambient-capable station receives a discovery signal sent by the ambient-capable access point. The discovery signal received by the ambient-capable station after associating with the ambient-capable access point carries at least one of the following: the SSID of the neighboring access point, primary channel information of the BSS corresponding to the neighboring access point, and transmission parameters of the beacon frame of the neighboring access point.

[0146] Optionally, the SSID of the neighboring access point may be a compressed SSID.

[0147] In some embodiments, the transmission parameters of the beacon frame of the neighboring access point include at least one of the following: beacon interval, TBTT, and time domain offset information between the discovery signal carrying the transmission parameters of the beacon frame of the neighboring access point and the TBTT (such as the most recent TBTT).

[0148] In some embodiments, the discovery signal received by the ambient energy station after associating with the ambient energy access point is a power supply signal of the ambient energy station after associating with the ambient energy access point.

[0149] In some embodiments, the channel and / or frequency band on which the environment-capable station receives the discovery signal after associating with the environment-capable access point is indicated by the environment-capable access point through at least one of the following frames: a beacon frame, a probe response frame, a management frame, and a control frame.

[0150] Specifically, for AMP STA, when it is not associated with an ambient energy access point, it obtains energy through the power supply signal on the preset channel and performs a scanning process. When the AMP STA is associated with an ambient energy access point, since the AMP STA may move out of the coverage of the ambient energy access point, it is also necessary to perform a scanning process to discover new APs. At this stage, the STA will scan on multiple channels, searching for beacon frames sent by the AP or actively sending probe request frames and waiting for probe response frames sent by the AP. The power consumption of this scanning process is unacceptable for the AMP STA. Similar to the purpose of introducing the WUR discovery frame in 802.11ba, the scanning process of the AMP STA also needs to consider a scanning method that reduces power consumption. Due to the need for AMP STA to be powered, the process of scanning for power supply signals can also be used as a process to scan nearby BSSs.

[0151] Specifically, the ambient energy access point (AMP AP) indicates the frequency band and channel of the power supply signal to the ambient energy station (AMP STA) through an AMP beacon frame or probe response frame, or other types of management frames or control frames. The AMP AP can carry the compressed SSID of the nearby AP and the primary channel information of the BSS corresponding to the AP on the power supply signal. On these channels, the AMP STA scans for the power supply signal. While obtaining power, these power supply signals also obtain the compressed SSID of the nearby AP and the primary channel information of the BSS corresponding to the AP, thereby reducing the power consumption and delay of the AMP STA when directly scanning multiple channels according to the existing STA scanning method. Furthermore, in addition to carrying the compressed SSID of the nearby AP and the primary channel information of the BSS corresponding to the AP, the power supply signal can also carry the transmission parameters of the Beacon frame, such as the beacon interval, target beacon transmission times (TBTTs), and the time offset between the (most recent) TBTT and the power supply signal carrying the above information. AMP STA can detect Beacon based on this information, which can reduce the power consumption required to detect Beacon frames.

[0152] In this embodiment, the discovery signal no longer serves solely as a discovery signal to assist the AMP STA in scanning for nearby BSSs; it also provides power, reducing power consumption. As shown in Figure 7, the AMP STA obtains the SSID and primary channel of the nearby BSS through the power signal on channel 1 and directly detects Beacon frames on channel 6.

[0153] In some embodiments, the process of BSS scanning performed by an AMP STA may be as shown in Figure 8. Specifically, the AMP STA may obtain wireless energy through a preset channel. When the energy collection conditions of the AMP STA are met (such as the communication conditions of the AMP STA are met), the AMP STA scans on at least one channel to receive beacon frames and associates with the target BSS.

[0154] In some embodiments, the process of AMP STA performing BSS scanning can be shown in Figure 9. During the scanning process to associate with the target BSS, the AMP STA may be unable to continue the scan due to power consumption. When the energy collected by the AMP STA is not enough to meet the work, it can continue to obtain energy through the wireless power supply signal on the preset channel. As shown in Figure 9, during the scanning process of the AMP STA, it is determined whether the energy collection meets the conditions (such as meeting the communication conditions of the AMP STA). If so, the scan continues. Otherwise, it is necessary to obtain energy through the wireless power supply signal on the preset channel.

[0155] Therefore, in an embodiment of the present application, the environmental energy site receives the discovery signal on at least one preset channel, so that the environmental energy access point can discover the environmental energy site, avoiding the environmental energy site from blindly detecting the discovery signal on all channels, reducing the delay in detecting the discovery signal, and reducing the energy consumed by the environmental energy site due to detecting the discovery signal, thereby ensuring the communication accessibility of the environmental energy site.

[0156] FIG10 is a schematic flowchart of a wireless communication method 300 according to an embodiment of the present application. As shown in FIG10 , the wireless communication method 300 may include at least part of the following contents:

[0157] S310, the ambient energy access point sends an energy supply signal on at least one preset channel;

[0158] S320: The environmental energy site receives an energy supply signal on at least one preset channel.

[0159] In an embodiment of the present application, the environmental energy site receives the power supply signal on at least one preset channel, avoiding the environmental energy site from blindly detecting the power supply signal on all channels, thereby providing energy to the environmental energy site more stably and efficiently, and ensuring the communication accessibility of the environmental energy site.

[0160] In an embodiment of the present application, the environmental energy site obtains the energy required for communication by collecting environmental energy (such as light energy, thermal energy, wind energy, radio frequency energy, mechanical energy, kinetic energy, etc.), and can support backscattering communication mode and active transmission communication mode.

[0161] In the embodiments of the present application, an ambient power site may also be referred to as an "Ambient power enabled IoT device" or "Ambient IoT device." Specifically, an ambient power IoT device refers to an IoT device that uses various ambient energies, such as radio frequency energy, light energy, solar energy, thermal energy, mechanical energy, and the like. An ambient IoT device may have no energy storage capability or may have very limited energy storage capability (e.g., using a capacitor with a capacity of tens of microfarads).

[0162] In an embodiment of the present application, an ambient energy access point (AMP AP) can be a device that communicates with an ambient energy station (AMP STA). It can be a conventional access point (AP) or, like an ambient energy station, obtain the energy required for communication by collecting ambient energy (such as light energy, thermal energy, wind energy, radio frequency energy, mechanical energy, kinetic energy, etc.).

[0163] In some embodiments, the ambient energy station can also be a zero-power device, featuring features such as being battery-free and maintenance-free. Specifically, a zero-power device has a simple structure, low complexity, and low cost. It can support energy harvesting from ambient energy (e.g., light, heat, radio frequency, mechanical, kinetic, etc.) to obtain the energy required for communication. It can support backscatter communication and, for some zero-power devices, can also support active transmission communication.

[0164] In some embodiments, in the above S320, the ambient energy station receives the energy supply signal on the at least one channel before associating with the ambient energy access point. That is, before the ambient energy station associates with the ambient energy access point, the ambient energy station receives the energy supply signal on at least one preset channel, thereby avoiding the ambient energy station blindly detecting the energy supply signal on all channels. This can provide energy to the ambient energy station more stably and efficiently, thereby ensuring the communication reachability of the ambient energy station.

[0165] In some embodiments, the power supply signal received on the at least one channel carries at least one of the following:

[0166] SSID of the ambient access point and the primary channel information of the BSS corresponding to the ambient access point.

[0167] For example, the SSID of the ambient energy access point carried by the energy supply signal received on the at least one channel may be a compressed SSID.

[0168] That is, in this embodiment, the ambient energy access point can carry its compressed SSID and the primary channel information of the BSS to which it corresponds in its power supply signal. The ambient energy access point scans for power supply signals on at least one preset channel. Upon receiving the power supply signal, the ambient energy access point also obtains its compressed SSID and the primary channel information of the BSS to which it corresponds. This prevents the ambient energy station from directly scanning all channels, reduces the delay in detecting power supply signals, and reduces the energy consumed by the ambient energy station during power supply signal detection.

[0169] In some embodiments, the power supply signal received on the at least one channel carries transmission parameters of a beacon frame of the ambient energy access point.

[0170] In some embodiments, the transmission parameters of the beacon frame of the environment-capable access point include but are not limited to at least one of the following: a beacon interval, a target beacon transmission time (TBTT), and time domain offset information between the power signal carrying the transmission parameters of the beacon frame of the environment-capable access point and the TBTT (such as the most recent TBTT).

[0171] That is, in this embodiment, the ambient energy access point can carry the transmission parameters of the beacon frame of the ambient energy access point on the power supply signal, so that the ambient energy station can detect the beacon frame of the ambient energy access point based on the transmission parameters of the beacon frame of the ambient energy access point, thereby reducing the delay in detecting the beacon frame and reducing the energy consumed by the ambient energy station due to detecting the beacon frame.

[0172] In some embodiments, the energy supply signal received by the ambient energy station on the at least one channel is also used to discover the ambient energy station. This allows the ambient energy access point to discover the ambient energy station, preventing the ambient energy station from blindly detecting discovery signals on all channels. This reduces the latency of detecting discovery signals and the energy consumed by the ambient energy station due to detecting discovery signals, thereby ensuring the communication reachability of the ambient energy station.

[0173] Specifically, in this embodiment of the present application, the network needs to provide a basic power supply signal for AMP STA operation. For example, the power supply signal can be sent on a preset channel in a certain frequency band. When the AMP STA is out of power, it can first obtain energy through the power supply signal on this preset channel to carry out subsequent operations. This prevents the AMP STA from scanning for power supply signals when there is no energy storage or the energy storage is very low.

[0174] In some embodiments, the at least one channel belongs to one or more frequency bands. Specifically, for example, the at least one preset channel includes a specific channel in a specific frequency band, such as channel 1 in the 2.4 GHz band, or channels 40, 44, 149, and 153 in the 5 GHz band, and also includes channels in frequency bands below 1 GHz. Before an ambient energy station is associated with an ambient energy access point, it can obtain energy through the at least one preset channel.

[0175] In some embodiments, the frequency band to which the at least one channel belongs is agreed upon by a protocol, and / or the frequency domain resources for the ambient energy station to receive the power supply signal within the at least one channel are agreed upon by a protocol.

[0176] For example, the frequency domain resources for receiving power supply signals in at least one channel of an ambient energy station can be part of the bandwidth of a 20MHz channel in the 2.4GHz band. The center frequencies of the 14 partially overlapping channels in the 2.4GHz band can be as shown in Table 1 above, with the center frequencies of different channels spaced 5MHz apart. The effective bandwidth of each channel is 20MHz, with an additional 2MHz as isolation bandwidth. For example, for an ambient energy station, when it is out of power, it is necessary to obtain a discovery signal on channel 1 in the 2.4GHz band in order to perform corresponding energy storage and then carry out subsequent work.

[0177] In some embodiments, the energy supply signal received by the environmental energy station on the at least one channel carries first indication information;

[0178] In which, the first indication information is used to indicate the information of the channel where the power supply signal of the environmental energy site is located (such as the channel number or channel index), or the first indication information is used to indicate the information of the channel set where the power supply signal of the environmental energy site is located (such as the channel set number or channel set index), or the first indication information is used to indicate the information of the frequency band where the power supply signal of the environmental energy site is located (such as the frequency band number or frequency band index).

[0179] For example, after obtaining stored energy through a power supply signal received on at least one preset channel, the channel or frequency band where other power supply signals are located can be directly obtained. For example, the first indication information can be directly carried on the power supply signal, which can indicate the channel number or frequency band number of other power supply. Specifically, after obtaining the first indication information, the environmental energy station can tune (retuning) to the corresponding channel or frequency band to obtain power. Specifically, the first indication information can also indicate a channel set (i.e., a first channel set) that includes multiple channels. After obtaining stored energy through a power supply signal received on at least one preset channel, the environmental energy station can scan on the channel or frequency band indicated by the first indication information to obtain other power supply signals. For example, the power supply signal received on a preset channel on channel 1 in the 2.4 GHz frequency band carries the first indication information, and the first indication information can indicate that the channel set (i.e., the first channel set) where other power supply signals are located includes channel 6, channel 7, and channel 8.

[0180] In some embodiments, when the first indication information is used to indicate information about the channel where the power supply signal of the environmental energy site is located, the channel where the power supply signal of the environmental energy site is located is the same as the channel through which the environmental energy site performs communication.

[0181] In some embodiments, when the first indication information is used to indicate information of a channel set where the power supply signal of the environmental energy site is located, the channel set where the power supply signal of the environmental energy site is located includes a channel on which the environmental energy site performs communication.

[0182] In some embodiments, when the first indication information is used to indicate the frequency band of the power supply signal of the environmental energy site, the frequency band of the power supply signal of the environmental energy site is the same as the frequency band in which the environmental energy site performs communication.

[0183] Specifically, in order to avoid the AMP STA from constantly retuning between the energy collection and communication channels, preferably, the energy supply signal and the communication-related channel are on the same channel or on the same frequency band.

[0184] In some embodiments, the energy supply signal received by the environmental energy station based on the first indication information carries second indication information; wherein,

[0185] The second indication information is used to indicate the channel number of the primary channel of the target BSS, and / or, the second indication information is used to indicate the frequency band number where the primary channel of the target BSS is located; or,

[0186] The second indication information is used to indicate the number of a channel in the channel set of the target BSS, and / or the second indication information is used to indicate the number of a frequency band where the channel in the channel set of the target BSS is located.

[0187] In some embodiments, the energy supply signal received by the environmental energy station on the at least one channel carries second indication information; wherein,

[0188] The second indication information is used to indicate the channel number of the primary channel of the target BSS, and / or, the second indication information is used to indicate the frequency band number where the primary channel of the target BSS is located; or,

[0189] The second indication information is used to indicate the number of a channel in the channel set of the target BSS, and / or the second indication information is used to indicate the number of a frequency band where the channel in the channel set of the target BSS is located.

[0190] Optionally, the primary channel of the target BSS is a channel through which beacon frames of the target BSS are sent.

[0191] In some embodiments, the second indication information is further used to indicate identification information of the target BSS.

[0192] In some embodiments, the primary channel of the target BSS is used for the environment-capable station to receive beacon frames, and / or, the primary channel of the target BSS is used for the environment-capable station to send probe request frames, and / or, the primary channel of the target BSS is used for the environment-capable station to receive probe response frames.

[0193] Optionally, the beacon frame may be an AMP beacon frame, which may be a dedicated beacon frame for an AMP STA.

[0194] Optionally, the probe request frame may be an AMP probe request frame, which may be a dedicated probe request frame for an AMP STA. Optionally, the probe response frame may be an AMP response request frame, which may be a dedicated response request frame for an AMP STA.

[0195] Specifically, the AMP STA can obtain the channel number of the main channel of the target BSS or the channel number in the channel set of the target BSS while obtaining power, thereby reducing the power consumption and delay of the subsequent AMP STA scanning on multiple channels to determine the primary channel of the target BSS. The AMP STA can receive the AMP beacon frame, or send the probe request frame and receive the probe response frame on the channel indicated by the second indication information. For example, the power supply signal received on channel 1 in the 2.4GHz frequency band carries the second indication information, indicating that the primary channel of the target BSS is channel 6. In addition to indicating the primary channel of the target BSS, the information carried in the power supply signal can also indicate the ID information of the target BSS.

[0196] In some embodiments, the waveform of the energy supply signal is generally a continuous wave (CW). The energy supply signal can carry information (such as second indication information) by amplitude modulation (such as OOK modulation). As shown in Figure 5, OOK modulation is performed in the energy supply signal to carry information 101010 as the second indication information. The energy supply signal can be used as a periodic signal to repeatedly send energy supply information. The energy supply signal can be sent in a certain frame structure, which includes a part that carries information and a part that does not carry information. Among them, the energy supply efficiency of the part that does not carry information is higher than that of the part that carries information.

[0197] In some embodiments, the beacon frame or probe response frame received by the ambient energy station on the main channel of the target BSS carries first power supply information; wherein, the first power supply information is used to indicate the channel and / or frequency band in which the ambient energy station receives the power supply signal after associating with the target BSS.

[0198] In some embodiments, the beacon frame or probe response frame received by the ambient energy station on the primary channel of the target BSS includes a radio frequency energy source information element, wherein the radio frequency energy source information element includes an operating class field and a channel field, the operating class field is used to indicate the frequency band in which the ambient energy station receives the power supply signal after associating with the target BSS, and the channel field is used to indicate the channel in which the ambient energy station receives the power supply signal after associating with the target BSS. For example, the radio frequency energy source information element may be as shown in FIG6.

[0199] For example, when the AMP STA receives the AMP beacon frame on the primary channel through the collected energy scan, it can obtain the parameters of the target BSS and carry out the subsequent association process. The AMP beacon frame can carry information related to the power supply signal, such as the frequency band and channel, so that the AMP STA can obtain power on the corresponding channel and communicate on the same or different channels. The power supply signal here is a power supply signal specific to the target BSS, which is used as the power supply signal required for the AMP STA to work in the target BSS. The frequency band and channel mentioned above can be indicated by the operating class and channel information. Among them, the operating class is an index number, which corresponds to a set of channel frequency ranges, channel bandwidths, channel center frequencies and specification requirements that need to be met.

[0200] In some embodiments, after the ambient energy station associates with the ambient energy access point, the ambient energy station receives a power supply signal sent by the ambient energy access point. The power supply signal received by the ambient energy station after associating with the ambient energy access point carries at least one of the following: the SSID of the neighboring access point, primary channel information of the BSS corresponding to the neighboring access point, and transmission parameters of the beacon frame of the neighboring access point.

[0201] Optionally, the SSID of the neighboring access point may be a compressed SSID.

[0202] In some embodiments, the transmission parameters of the beacon frame of the neighboring access point include at least one of the following: beacon interval, TBTT, and time domain offset information between the power signal carrying the transmission parameters of the beacon frame of the neighboring access point and the TBTT (such as the most recent TBTT).

[0203] In some embodiments, the power supply signal received by the ambient energy station after associating with the ambient energy access point is a discovery signal of the ambient energy station after associating with the ambient energy access point.

[0204] In some embodiments, the channel and / or frequency band on which the ambient-enabled station receives the power supply signal after associating with the ambient-enabled access point is indicated by the ambient-enabled access point through at least one of the following frames: a beacon frame, a probe response frame, a management frame, and a control frame.

[0205] Specifically, for AMP STA, when it is not associated with an ambient energy access point, it obtains energy through the power supply signal on the preset channel and performs a scanning process. When the AMP STA is associated with an ambient energy access point, since the AMP STA may move out of the coverage of the ambient energy access point, it is also necessary to perform a scanning process to discover new APs. At this stage, the STA will scan on multiple channels, searching for beacon frames sent by the AP or actively sending probe request frames and waiting for probe response frames sent by the AP. The power consumption of this scanning process is unacceptable for the AMP STA. Similar to the purpose of introducing the WUR discovery frame in 802.11ba, the scanning process of the AMP STA also needs to consider a scanning method that reduces power consumption. Due to the need for AMP STA to be powered, the process of scanning for power supply signals can also be used as a process to scan nearby BSSs.

[0206] Specifically, the ambient energy access point (AMP AP) indicates the frequency band and channel of the power supply signal to the ambient energy station (AMP STA) through an AMP beacon frame or probe response frame, or other types of management frames or control frames. The AMP AP can carry the compressed SSID of the nearby AP and the primary channel information of the BSS corresponding to the AP on the power supply signal. On these channels, the AMP STA scans for the power supply signal. While obtaining power, these power supply signals also obtain the compressed SSID of the nearby AP and the primary channel information of the BSS corresponding to the AP, thereby reducing the power consumption and delay of the AMP STA when directly scanning multiple channels according to the existing STA scanning method. Furthermore, in addition to carrying the compressed SSID of the nearby AP and the primary channel information of the BSS corresponding to the AP, the power supply signal can also carry the transmission parameters of the Beacon frame, such as the beacon interval, target beacon transmission times (TBTTs), and the time offset between the (most recent) TBTT and the power supply signal carrying the above information. AMP STA can detect Beacon based on this information, which can reduce the power consumption required to detect Beacon frames.

[0207] In this embodiment, the power signal no longer serves solely as a power supply; it can also serve as a discovery signal to assist the AMP STA in scanning for nearby BSSs, reducing power consumption. As shown in Figure 7, the AMP STA obtains the SSID and primary channel of the nearby BSS through the power signal on channel 1 and directly detects Beacon frames on channel 6.

[0208] In some embodiments, the process of BSS scanning performed by an AMP STA may be as shown in Figure 8. Specifically, the AMP STA may obtain wireless energy through a preset channel. When the energy collection conditions of the AMP STA are met (such as the communication conditions of the AMP STA are met), the AMP STA scans on at least one channel to receive beacon frames and associates with the target BSS.

[0209] In some embodiments, the process of AMP STA performing BSS scanning can be shown in Figure 9. During the scanning process to associate with the target BSS, the AMP STA may be unable to continue the scan due to power consumption. When the energy collected by the AMP STA is not enough to meet the work, it can continue to obtain energy through the wireless power supply signal on the preset channel. As shown in Figure 9, during the scanning process of the AMP STA, it is determined whether the energy collection meets the conditions (such as meeting the communication conditions of the AMP STA). If so, the scan continues. Otherwise, it is necessary to obtain energy through the wireless power supply signal on the preset channel.

[0210] Therefore, in an embodiment of the present application, the environmental energy site receives the power supply signal on at least one preset channel, avoiding the environmental energy site from blindly detecting the power supply signal on all channels, thereby providing energy to the environmental energy site more stably and efficiently, and ensuring the communication accessibility of the environmental energy site.
