[0024] The technical solutions in the present application will be described below with reference to the accompanying drawings.

[0025] Ambient Internet of Things (A-IoT)

[0026] A-IoT communication adopts energy harvesting and backscattering communication technology. An A-IoT device refers to an IoT device that is driven by various environmental energies such as wireless radio frequency energy, light energy, solar energy, thermal energy, mechanical energy, and the like. Such a device can have no energy storage capability or can have very limited energy storage capability (such as using a capacitor with a capacity of tens of microfarads (uF)). Compared with a traditional Internet of Things (IoT) device, an A-IoT device has many advantages such as no conventional battery, no maintenance, small size, low complexity, low cost, long service life, and the like.

[0027] In some scenarios, an A-IoT device can also be referred to as a zero-power device or an AMP device.

[0028] An ambient Internet of Things can include a network device 110 and an A-IoT device 120, as shown in FIG. 1. The network device is used to send a wireless energy supply signal, a downlink communication signal to the A-IoT device, and receive a backscattering signal of the A-IoT device. A basic A-IoT device includes an energy harvesting module, a backscattering communication module, and a low-power computing module. In addition, the A-IoT device can also have a memory or a sensor for storing some basic information (such as an article identifier) or obtaining environmental temperature, environmental humidity, and the like.

[0029] It should be noted that FIG. 1 exemplarily shows one network device and one A-IoT device. Alternatively, the communication system 100 can include a plurality of network devices, and each network device can include other numbers of A-IoT devices within its coverage range, which is not limited in the embodiments of the present application.

[0030] In addition, in some implementations, the communication system 100 can also include a network controller, a mobile management entity, and other network entities, which are not limited in the embodiments of the present application.

[0031] It should be understood that the technical solutions of the embodiments of the present application can be applied to various communication systems, for example: a 5th generation (5G) system or new radio (NR), a long term evolution (LTE) system, an LTE frequency division duplex (FDD) system, an LTE time division duplex (TDD), a cellular Internet of Things (IoT), and the like. The technical solutions provided in the present application can also be applied to future communication systems, such as a 6th generation mobile communication system, and the like.

[0032] The A-IoT device in the embodiments of the present application can be used as a terminal device, which can also be referred to as a user equipment (UE), an access terminal, a user unit, a user station, a mobile station, a mobile station (MS), a mobile terminal (MT), a remote station, a remote terminal, a mobile device, a user terminal, a terminal device, a wireless communication device, a user agent, or a user apparatus. The terminal device in the embodiments of the present application can be a device that provides voice and / or data connectivity for a user, and can be used to connect people, things, and machines, such as household appliances, sensors, electronic tags, and the like with wireless connection functions. The terminal in the embodiments of the present application can be a wireless terminal in a smart home, a wireless terminal in an IWSN, a wireless terminal in smart logistics and smart warehousing, a wireless terminal in self driving, a wireless terminal in remote medical surgery, a wireless terminal in a smart grid, a wireless terminal in transportation safety, a wireless terminal in a smart city, and the like.

[0033] The network device in the embodiments of the present application can be a device for communicating with a terminal device. If the terminal is an electronic tag, the network device can be a reader / writer (for example, a reader / writer based on radio frequency identification (RFID) technology) for reading and writing the electronic tag. The network device can also be an access network device or a radio access network device, for example, the network device can be a base station. The network device in the embodiments of the present application can refer to a radio access network (RAN) node (or device) for accessing a terminal device to a wireless network. The base station can broadly cover various names in the following or be replaced by the following names, such as: Node B (NodeB), evolved Node B (eNB), next generation Node B (gNB), relay station, access point, transmitting and receiving point (TRP), transmitting point (TP), master station MeNB, auxiliary station SeNB, multi-standard radio (MSR) node, home base station, network controller, access node, wireless node, access point (AP), transmission node, transceiver node, baseband unit (BBU), remote radio unit (RRU), active antenna unit (AAU), remote radio head (RRH), central unit (CU), distributed unit (DU), positioning node, etc. The base station can be a macro base station, a micro base station, a relay node, a donor node or the like, or a combination thereof. The base station can also refer to a communication module, modem or chip for being arranged in the foregoing device or apparatus. The base station can also be a mobile switching center and a device for device-to-device (D2D), vehicle-to-everything (V2X), machine-to-machine (M2M) communication, a network side device in a 6G network, a device for a base station function in a future communication system, etc. The base station can support networks of the same or different access technologies. The embodiments of the present application do not limit the specific technology and specific device form adopted by the network device.

[0034] A base station can be fixed or mobile. For example, a helicopter or an unmanned aerial vehicle (UAV) can be configured to function as a mobile base station, and one or more cells can move according to the location of the mobile base station. In other examples, a helicopter or an unmanned aerial vehicle can be configured to function as a device that communicates with another base station.

[0035] In some deployments, the network device in the embodiments of the present application can refer to a CU or a DU, or the network device includes a CU and a DU. The gNB can also include an AAU.

[0036] The network device and the terminal device can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; can also be deployed on the water surface; can also be deployed on aircraft, balloons and satellites in the air. The scene where the network device and the terminal device are located in the embodiments of the present application is not limited.

[0037] It should be understood that all or part of the functions of the communication device in the present application can also be implemented by software functions running on hardware, or by virtualized functions instantiated on a platform (such as a cloud platform).

[0038] In some implementations, the terminal 120 can include an energy harvesting module 121 and a backscatter communication module 122. In some cases, the terminal 120 can also include a low-power computing module 123. The low-power computing module 123 is configured to provide computing functions for the terminal, such as data processing, etc. In other cases, the terminal 120 can also include a sensor 124 for collecting external information (such as ambient temperature, ambient humidity, etc.). In other cases, the terminal 120 can also include a memory 125 for storing some information (such as external information collected by the above-mentioned sensor, or, for example, an article identifier, etc.).

[0039] The energy harvesting module 121 described above is configured to harvest energy. In some implementations, energy can be harvested through a wireless energy supply signal transmitted by the network device. The wireless energy supply signal can be a "radio frequency signal" transmitted by the network device, so the energy harvesting module is also called a "radio frequency energy harvesting module".

[0040] The backscattering communication module 122 is configured to perform backscattering communication between the terminal and the network device. For example, the terminal 120 receives a wireless signal transmitted by the network device 110, and modulates the wireless signal to load information to be transmitted. Finally, the modulated signal is radiated from the antenna, and this information transmission process is called backscattering communication. The backscattering communication and the load modulation function are inseparable. The load modulation adjusts and controls the circuit parameters of the oscillation loop of the terminal according to the beat of the data stream, so that the size and other parameters of the impedance of the terminal change, thereby completing the modulation process. The load modulation technology mainly includes resistance load modulation and capacitance load modulation.

[0041] In some implementations, other devices such as an amplifier can also be arranged on the transport (TX) path of the network device 110 to process the signal to be transmitted. Other devices such as a low noise amplifier (LNA) can also be arranged on the receive (RX) path of the network device 110 to process the received signal.

[0042] In another implementation, the terminal 120 can be provided with an energy harvesting unit to harvest the energy of the wireless energy signal transmitted by the network device. Of course, the terminal 120 can also be provided with a logic processing unit to perform corresponding calculation functions.

[0043] Classification of A-IoT devices

[0044] In some scenarios, A-IoT devices can be classified into three categories based on their energy sources and energy usage: passive A-IoT devices, semi-passive A-IoT devices, and active A-IoT devices.

[0045] I. Passive A-IoT devices

[0046] Passive A-IoT devices usually do not need to be equipped with a battery. When the A-IoT device is close to the network device, the A-IoT device is in the near-field range formed by the antenna radiation of the network device. At this time, the antenna of the A-IoT device can generate an induced current through electromagnetic induction, and the induced current can provide energy for the A-IoT device to implement demodulation of the received signal, and / or modulation, coding, and other operations on the to-be-transmitted signal. In some implementations, the passive A-IoT device described above can be an electronic tag, and correspondingly, the network device can be a reader / writer of a radio frequency identification (RFID) system, which is configured to read the content of the electronic tag and / or to change the content of the electronic tag.

[0047] II. Semi-passive A-IoT device

[0048] The semi-passive A-IoT device does not install a regular battery itself, but can use the energy harvesting module 121 to harvest radio wave energy, and meanwhile store the harvested energy in an energy storage unit (such as a capacitor). After the energy storage unit obtains energy, it can power the A-IoT device to implement demodulation of a received signal, and / or modulation, coding, etc. of a to-be-transmitted signal.

[0049] III. Active A-IoT device

[0050] The active A-IoT device can be built-in with a battery. The battery can power the A-IoT device to implement demodulation of a received signal, and / or modulation, coding, etc. of a to-be-transmitted signal. However, when the A-IoT device communicates by using the backscatter technology, the A-IoT device does not need to consume the energy of the battery. Therefore, for such an A-IoT device, "zero power consumption" mainly refers to the scenario in which the terminal communicates by using the backscatter technology.

[0051] In some implementations, the active A-IoT device described above can be an electronic tag, and the network device can be an RFID reader. In this case, the built-in battery can power the RFID chip in the A-IoT device to increase the read-write distance between the RFID reader and the electronic tag. On the other hand, the built-in battery can power the RFID chip in the A-IoT device to shorten the read-write latency of the RFID reader to the electronic tag, which is beneficial to improve the reliability of communication.

[0052] For the passive A-IoT device and the semi-passive A-IoT device described above, since there is no built-in battery in the A-IoT device, the A-IoT device needs to collect energy from the environment (power harvesting). On the one hand, the A-IoT device can drive the circuit to perform data reception or data transmission only when the environmental energy collected by the A-IoT device reaches a certain amount. Before the A-IoT device collects enough energy, the A-IoT device cannot perform data reception or transmission. On the other hand, when the A-IoT device performs data reception or data transmission, the stored energy will be consumed. When the stored energy is lower than a certain amount, the A-IoT device cannot perform data reception or transmission any more. At this time, the A-IoT device needs to continue to obtain energy from the environment so as to continue to perform data reception or transmission subsequently.

[0053] In some other scenarios, based on the type of the transmitter, the A-IoT device can be divided into three categories including the following types: A-IoT device based on backscatter, A-IoT device based on active transmitter, and A-IoT device with both backscatter and active transmitter.

[0054] 1) A-IoT device based on backscattering.

[0055] Such A-IoT device uses the backscattering mode for uplink data transmission as described above. Such device does not have an active transmitter for active transmission, but only has a backscattering transmitter. Therefore, when such terminal transmits data, the network device needs to provide a carrier, and the terminal device performs backscattering based on the carrier to realize data transmission.

[0056] 2) A-IoT device based on active transmitter.

[0057] Such A-IoT device uses an active transmitter with active transmission capability for uplink data transmission, so such A-IoT device can transmit data using its own active transmitter when transmitting data, without the need for the network device to provide a carrier. The active transmitter suitable for A-IoT device may be, for example, an ultra-low-power ASK, an ultra-low-power FSK transmitter, etc. Based on the current implementation, the overall power consumption of such transmitter can be reduced to 400-600uw when transmitting a 100uw signal.

[0058] 3) A-IoT device with both backscattering and active transmitter.

[0059] Such terminal can support both backscattering and active transmitter. The terminal can determine which transmission mode of uplink signal to use, backscattering or active transmitter for active transmission, according to different situations (such as the situation of power, available environmental energy), or based on the scheduling of the network device.

[0060] Low-power Internet of Things based on cellular network

[0061] Cellular Internet of Things is booming, and 3GPP has standardized Internet of Things technologies such as narrow band Internet of Things (NB-IoT), machine type communication (MTC), reduced capability (RedCap), etc. However, there are still many Internet of Things communication needs in various scenarios that cannot be met by existing technologies, such as: harsh communication environment (high temperature, extremely low temperature, high humidity, high pressure, high radiation or high-speed movement, etc.), extremely small terminal form factor requirement, extremely low cost, etc.

[0062] Therefore, in order to cover these unmet Internet of Things communication needs, ultra-low-cost, extremely small size, battery-free / maintenance-free Internet of Things are needed in cellular networks, and environmental Internet of Things can exactly meet this demand.

[0063] Based on the discussion of A-IoT application scenarios in 3GPP system architecture (SA) 1, A-IoT can be used for at least four types of scenarios as follows:

[0064] • Object identification, such as logistics, production line product management, supply chain management.

[0065] • Environmental monitoring, such as temperature, humidity, harmful gas monitoring of working environment and natural environment.

[0066] • Positioning, such as indoor positioning, intelligent lost-and-found, production line article positioning, etc.

[0067] • Intelligent control, such as intelligent control of various appliances in smart home (turning on / off air conditioner, adjusting temperature), intelligent control of various facilities in agricultural greenhouse (automatic irrigation, fertilization).

[0068] In the low-power Internet of Things based on cellular network, the A-IoT device can directly transmit and receive carrier, data or signal from the network device, and transmit or backscatter data or channel to the network device (e.g., base station or AP), as shown in FIG. 2 (denoted as the first topology). Alternatively, the communication between the A-IoT and the network device is implemented through an intermediate node, in which case the intermediate node transmits carrier, data or signal to the A-IoT device, the A-IoT device transmits or backscatters data or signal to the intermediate node, and the intermediate node transmits the received data or signal to the network device, as shown in FIG. 3 (denoted as the second topology).

[0069] In the embodiments of the present application, the intermediate node is not limited. In some implementations, the intermediate node can be a terminal device. In other implementations, the intermediate node can be a network device. In other implementations, the intermediate node can be an integrated access and backhaul (IAB) node.

[0070] Assistant node

[0071] In some scenarios, an assistant node is introduced to assist the network device in communicating with the A-IoT device (also referred to as ambient power (AMP) device). For example, the assistant node transmits carrier to the A-IoT device, so that the A-IoT device communicates with the network device based on the backscattering of the carrier.

[0072] Energizer

[0073] In some scenarios, an energizer is introduced to assist a network device to communicate with an A-IoT device (also referred to as an ambient power (AMP) device). For example, the energizer provides energy and / or wireless power to the A-IoT device, so that the A-IoT device communicates with the network device based on the harvested energy and / or wireless power.

[0074] In some implementations, the energizer can send a wake-up signal to the A-IoT device to wake up the A-IoT device.

[0075] In some implementations, the energizer can connect to an access point (AP) (as an example of a network device) through a wireless interface (e.g., WiFi).

[0076] In embodiments of the present application, the relationship between the above-mentioned assisting node, intermediate node and energizer is not limited. In some implementations, the assisting node and the energizer can be deployed on the same device. Of course, in embodiments of the present application, the assisting node and the energizer can be independently deployed.

[0077] In other implementations, the assisting node and the intermediate node can be deployed on the same device. Of course, in embodiments of the present application, the assisting node and the intermediate node can be independently deployed. In other implementations, the assisting node, the energizer and the intermediate node can all be deployed on the same device. Of course, in embodiments of the present application, the assisting node, the energizer and the intermediate node can be independently deployed.

[0078] In embodiments of the present application, the energizer introduced above can be taken as an example of a first device below, and correspondingly, the AMP device or A-IoT device introduced above can be taken as an example of a second device below. The AMP device may, for example, be an AMP station (STA) or an AMP non-AP STA.

[0079] At present, the energizer (also referred to as a first device) is a new type of device, and its functions, control mechanisms and signal transmission have not been researched. Therefore, for a network device and a second device, it is not possible to determine how the first device assists the network device to communicate with the second device.

[0080] To address the above problem, embodiments of the present application propose that the network device can send control information to the first device to control the first device to assist the second device to communicate with the network device. A schematic flowchart of a method of wireless communication in embodiments of the present application is introduced below in conjunction with FIG. 4. The method shown in FIG. 4 includes step S410.

[0081] In step S410, the network device sends control information to the first device, the control information being used to control the first device to assist the second device to communicate with the network device.

[0082] In some implementations, the control information is used to control one or more of the following: transmission of the first signal; transmission of the wake-up signal of the second device; transmission of the downlink PPDU; transmission of the preamble; operating state of the first device.

[0083] For example, in the case that the control information is used to control transmission of the first signal, in some implementations, the first signal is used to provide energy and / or wireless power for the second device, for example, the first signal can be a wireless power transfer (WPT) signal or a WPT physical layer protocol data unit (PPDU). Of course, in the embodiments of the present application, the first signal can also be understood as a signal in a first field in the WPT PPDU, wherein the first field is used to carry a signal for providing energy and / or wireless power. In some scenarios, the field in the WPT PPDU used to carry a signal for providing energy and / or wireless power can be referred to as a “charging field”.

[0084] In some implementations, the control information indicates one or more of the following: waveform of the first signal; frequency information of the first signal; PPDU format of the first signal; downlink PPDU format; whether to start transmission of the first signal; transmission time of the first signal; beam information of the first signal; LBT information associated with the first signal; transmission power information of the first signal; whether the first device only transmits a field for providing energy and / or wireless power; whether the first signal is used to provide energy and / or wireless power for an active device or a backscatter device.

[0085] In some implementations, the waveform of the first signal indicated by the control information can include a waveform of a WPT signal.

[0086] In some implementations, the frequency information of the first signal indicated by the control information includes one or more of the following: frequency band for transmitting the first signal, center frequency of the first signal, frequency domain range of the first signal.

[0087] For example, if the frequency information of the first signal indicated by the control information includes the frequency band for transmitting the first signal, the control information is used to indicate whether the frequency band of the WPT signal is S1G (Sub 1GHz).

[0088] In some implementations, the PPDU format of the first signal indicated by the control information can include a PPDU format of a WPT PPDU.

[0089] In some embodiments, the control information indicating the downlink PPDU format can comprise the control information indicating whether the downlink PPDU format is a PPDU format that can be used for 2.4 GHz, wherein the downlink PPDU can be understood as a PPDU transmitted by the network device to the second device through the first device, or the downlink PPDU can be understood as a PPDU transmitted by the network device to the second device.

[0090] In some embodiments, the control information indicating whether to start the transmission of the first signal can comprise the control information indicating whether to start the transmission of the WPT signal (denoted as “WPT on / off”).

[0091] In some embodiments, the control information indicating the transmission time of the first signal can comprise the control information indicating the transmission time of the first signal based on one or more of the following: the transmission period of the first signal, the duration of the on transmission of the first signal, the duration of the off transmission of the first signal, and the start transmission time of the first signal.

[0092] For example, the first signal is a WPT signal, and the duration of the on transmission of the first signal is also referred to as “WPT on duration”. Correspondingly, the duration of the off transmission of the first signal is also referred to as “WPT off duration”.

[0093] For another example, the first signal is a signal carried by the first domain, and correspondingly, the start transmission time of the first signal can be understood as the start time of the first domain, or in other words, the time of starting to transmit the first domain.

[0094] In some embodiments, the beam information of the first signal indicated by the control information can indicate that the first signal is transmitted using an omni-directional beam or a beamforming technology.

[0095] In some embodiments, if the beam information of the first signal indicates that the first signal is transmitted using a beamforming technology, the beam information of the first signal can be used to indicate a parameter associated with the beamforming technology.

[0096] In the embodiments of the present application, the parameter associated with the beamforming technology is not limited. For example, the parameter associated with the beamforming technology can comprise a parameter indicating a beam width and / or a parameter indicating a beam direction.

[0097] In some embodiments, the listen before talk (LBT) information associated with the first signal indicated by the control information can indicate one or more of the following: whether the first signal is allowed to be superimposed and transmitted with other signals, whether the LBT is activated for the first device, and an LBT parameter.

[0098] In some implementations, the LBT information is used to indicate whether the first signal is allowed to be superposed with other signals, which can be understood as the LBT information is used to indicate whether the first signal is allowed to be superposed with other first signals transmitted by other first devices.

[0099] In the embodiments of the present application, the LBT parameter is not limited. In some implementations, the LBT parameter can include an LBT threshold, which is used to determine whether the listened channel is idle.

[0100] In some implementations, the transmission time of the first signal can be a time window, and the first device can perform LBT in the time window to determine whether the channel is idle.

[0101] In some implementations, the transmission power information of the first signal indicated by the control information can include an initial transmission power of the first signal and / or a power adjustment parameter. For example, the power adjustment parameter is used to increase or decrease the transmission power of the first signal on the basis of the initial transmission power. For another example, the power adjustment parameter is used to increase or decrease the level of the transmission power of the first signal on the basis of the transmission power level corresponding to the initial transmission power.

[0102] For example, the first signal is a signal carried by the first domain, and accordingly, the transmission power information of the first signal can include an initial transmission power of the first domain and / or a power adjustment parameter.

[0103] In some scenarios, the network device and the first device can both communicate with the second device (for example, in the scheme shown in FIG. 3), at this time, the network device can indicate, through the control information, which parts (or fields) in the PPDU need to be transmitted by the first device. For example, the control information is used to indicate whether the first device only transmits the field for providing energy and / or wireless power. In some scenarios, the field for providing energy and / or wireless power is also called the energizing part.

[0104] Accordingly, in some implementations, the parts (for example, the preamble and / or the downlink data) in the PPDU other than the energizing part can be transmitted by the network device to the second device.

[0105] In some implementations, the control information is used to indicate that the first signal is used to provide energy and / or wireless power for an active device or a backscatter device. For example, if the control information indicates that the first signal is used to provide energy and / or wireless power for an active device, the first signal can be transmitted in the 2.4 GHz frequency band. For another example, if the control information indicates that the first signal is used to provide energy and / or wireless power for a backscatter device, the first signal can be transmitted in the S1G frequency band.

[0106] It should be noted that in some scenarios, the first signal can also be a backscatter signal, which is used for backscatter communication between the second device and the network device. Of course, in the embodiments of the present application, the first signal and the backscatter signal can be different signals.

[0107] For example, the control information is used to control the transmission of the wake-up signal, in some implementations, the wake-up signal is used to wake up the exciter and / or the second device.

[0108] In some implementations, the control information is used to indicate the transmission parameter of the wake-up signal. For example, the wake-up signal is carried in a PPDU, and the transmission parameter of the wake-up signal is used to determine the PPDU format of the wake-up signal. In the embodiments of the present application, the transmission parameter is not limited. For example, the transmission parameter can include a data rate and / or a modulation mode.

[0109] For example, the control information is used to control the transmission of the preamble, in some implementations, the control information is used to indicate one or more of the following: the waveform of the preamble, the transmission time of the preamble, the format of the preamble.

[0110] For example, the control information is used to control the working state of the first device, in some implementations, the control information is used to indicate one or more of the following: the first device is in sleep (or said to be in sleep state); the first device is activated (or said to be in active state); the sleep time of the first device; the activation time of the first device.

[0111] The control information in the embodiments of the present application is introduced above, and the transmission mode of the control information in the embodiments of the present application is introduced below. In some implementations, the control information can be carried in one or more frames. For example, the information for indicating the activation of the first device can be carried in a first frame with the first signal, and correspondingly, the information in the above control information except the information for indicating the activation of the first device (for example, the frequency information for indicating the first signal and / or the information for indicating the format of the downlink PPDU) can be carried in a second frame.

[0112] In some implementations, the control information can be transmitted based on a preconfigured mode. For example, the network device can send the control information to the first device in a preconfigured mode, and correspondingly, the control information is valid for a period of time, and during this period of time, the first device can communicate based on the control information.

[0113] In some embodiments, the control information can be transmitted in a dynamic indication manner. For example, the network device can dynamically indicate the control information to the first device each time the first device is activated. That is, if the control information is transmitted in the dynamic indication manner, the method further includes: the network device sending a first request to the first device, the first request being used to request the first device to provide energy and / or wireless power for the second device (or the first request being used to request to activate the first device), and the first request carrying the control information.

[0114] In some embodiments, the first device can send a response message to the network device for the first request, the response message being used to indicate whether the first device accepts to provide energy and / or wireless power for the second device. Of course, in the embodiments of the present application, the first device can also not send the response message to the network device for the first request, so as to reduce the overhead of transmitting the response message.

[0115] It should be noted that the dynamic indication manner and the pre-configuration manner described above can be used alone or in combination in the embodiments of the present application. In some embodiments, part of the control information can be transmitted in the dynamic indication manner, and another part of the control information can be transmitted in the pre-configuration manner. For example, if the control information is transmitted in the pre-configuration manner, the control information is used to indicate the waveform of the first signal; and / or if the control information is transmitted in the dynamic indication manner, the control information is used to indicate one or more of the following: whether to start the transmission of the first signal, the transmission time of the first signal, the PPDU format of the first signal, and the PPDU format of the downlink signal.

[0116] The embodiments of the present application do not limit the manner of transmitting the first signal in the transmission time described above. In some embodiments, the first device can directly transmit the first signal in the transmission time of the first signal indicated by the control information without performing LBT to determine whether the channel is idle. In other embodiments, the first device can first perform LBT in the transmission time of the first signal indicated by the control information to determine whether the channel is idle, and transmit the first signal if the channel is idle.

[0117] In other embodiments, the network device can pre-configure the control information for the first device in a pre-configuration manner, and then activate the control information in a dynamic indication manner. In this way, it is helpful to reduce the overhead of transmitting information in the process of dynamic indication. That is, if the control information is transmitted in the pre-configuration manner, the method further includes: the network device sending first indication information to the first device, the first indication information being used to indicate to activate the control information carried by the pre-configuration information.

[0118] In some embodiments, the first indication information is carried in the first request, and the first request is used to request the first device to provide energy and / or wireless power for the second device. That is, the first indication information can be indicated to the first device in each activation process of the first device.

[0119] In some embodiments, the method further includes: in response to receiving the first request, the first device sends the first signal to the second device based on the control information.

[0120] In some scenarios, the network device sending the control information to the first device can be triggered by the second device through a third request. That is, the method further includes: the second device sends a third request to the network device, and the third request is used to provide energy and / or wireless power for the second device. Accordingly, the network device can send the control information to the first device. For related introduction, please refer to FIG. 6.

[0121] At present, different types of first devices have different capabilities in the communication system. In some scenarios, the first device can send first information for determining the capability related to the first signal to the network device, so that the network device controls the communication of the first device based on the capability of the first device, which helps to improve the rationality of the network device controlling the first device. Of course, in the embodiments of the present application, the scheme for indicating the capability can be used independently of the related scheme of the control information introduced in the foregoing, for example, the network device can select a suitable first device to provide energy and / or wireless power for the second device based on the capability of the first device.

[0122] In some embodiments, the method further includes: the first device sends first information to the network device, and the first information is used to determine the capability of the first device related to the first signal. Taking the first signal as WPT for example, the capability is also referred to as WPT-related capability.

[0123] In some embodiments, the first information is used to indicate one or more of the following: the position of the first device; whether the first device is an active device; the bandwidth supported by the first device for transmitting the first signal; the frequency band supported by the first device for transmitting the first signal; the transmission power supported by the first device for transmitting the first signal; whether the transmission power of the first device for transmitting the first signal is adjustable; whether the first device supports transmitting the first signal based on beamforming; the second device provided with energy and / or wireless power by the first device; and the maximum transmission power supported by the first device.

[0124] Taking the first information used to indicate the location of the first device as an example, the location of the first device helps the network device determine the capabilities of the first device associated with the first signal (e.g., the efficiency with which the first device provides power and / or wireless power). For example, if the location of the first device is far from the location of the second device, the efficiency of the first device in providing power and / or wireless power to the second device is low. In this case, the capability of the first device is low, and therefore, the network device may not select the first device to provide power and / or wireless power to the second device. Conversely, if the location of the first device is close to the location of the second device, the efficiency of the first device in providing power and / or wireless power to the second device is high. In this case, the capability of the first device is high, and therefore, the network device may select the first device to provide power and / or wireless power to the second device.

[0125] Taking the first information used to indicate whether the first device is an active device as an example, whether the first device is an active device can be understood as whether the first device is powered by a battery.

[0126] In some implementations, whether the first device is an active device helps the network device determine the capabilities of the first device associated with the first signal (e.g., the amount of power and / or wireless power the first device can provide). For example, if the first device is an active device, it can provide a greater amount of power and / or wireless power, thus its capability is higher, and the network device can accordingly select the first device to provide power and / or wireless power to the second device. Conversely, if the first device is not an active device (e.g., a passive device), it can provide a smaller amount of power and / or wireless power, thus its capability is lower, and the network device may not select the first device to provide power and / or wireless power to the second device.

[0127] Taking the first information used to indicate the bandwidth supported by the first device for transmitting the first signal as an example, the bandwidth supported by the first device for transmitting the first signal helps the network device determine the capabilities of the first device related to the first signal (e.g., the efficiency of the first device in providing power and / or wireless power). For example, if the bandwidth supported by the first device for transmitting the first signal is large, the first device can provide power and / or wireless power to the second device in a shorter time. Accordingly, the efficiency of the first device in providing power and / or wireless power to the second device is high. Therefore, the network device can select the first device to provide power and / or wireless power to the second device. Conversely, if the bandwidth supported by the first device for transmitting the first signal is small, the first device may not be able to provide power and / or wireless power to the second device in a shorter time. Accordingly, the efficiency of the first device in providing power and / or wireless power to the second device is low. Therefore, the network device may not select the first device to provide power and / or wireless power to the second device.

[0128] For example, the first signal is the signal carried by the first domain, and correspondingly, the bandwidth supported by the first device for transmitting the first signal can be understood as the bandwidth supported by the first device for transmitting the first domain.

[0129] For example, if the first signal is a WPT signal, then the bandwidth supported by the first device for transmitting the first signal can be understood as the bandwidth supported by the first device for transmitting the WPT signal.

[0130] Taking the first information used to indicate the frequency band that the first device supports for transmitting the first signal as an example, in some scenarios, the frequency band for transmitting the first signal may include S1G for transmitting WPT signals and / or 2.4GHz for transmitting WPT PPDU.

[0131] For example, if the first signal is a WPT signal, then the frequency band supported by the first device for transmitting the first signal can be understood as the frequency band (or operating frequency band) supported by the first device for transmitting the WPT signal.

[0132] Taking the first information used to indicate the transmission power supported by the first device for transmitting the first signal as an example, the transmission power supported by the first device for transmitting the first signal helps the network device determine the capabilities of the first device associated with the first signal (e.g., the efficiency of the first device in providing power and / or wireless power). For example, if the first device supports a higher transmission power for transmitting the first signal, the first device is more efficient in providing power and / or wireless power to the second device; therefore, the network device can select the first device to provide power and / or wireless power to the second device. Conversely, if the first device supports a lower transmission power for transmitting the first signal, the first device is less efficient in providing power and / or wireless power to the second device; therefore, the network device may not select the first device to provide power and / or wireless power to the second device.

[0133] In some implementations, the transmission power of the first signal can be the maximum transmission power of the first device for transmitting the first signal in a certain frequency band.

[0134] Taking the first information used to indicate whether the first device supports adjustable transmission power for transmitting the first signal as an example, whether the first device supports adjustable transmission power for transmitting the first signal helps the network device determine the capabilities of the first device related to the first signal (e.g., the efficiency of the first device in providing power and / or wireless power). For example, if the first device supports adjustable transmission power for transmitting the first signal, the transmission power of the first signal can be adjusted based on the distance between the first device and the second device. In this case, the first device is more efficient in providing power and / or wireless power, and therefore, the network device can select the first device to provide power and / or wireless power to the second device. As another example, if the first device supports non-adjustable transmission power for transmitting the first signal, the transmission power of the first signal cannot be adjusted based on the distance between the first device and the second device. In this case, if the first device and the second device are far apart, the first device is less efficient in providing power and / or wireless power, and therefore, the network device may not select the first device to provide power and / or wireless power to the second device.

[0135] Taking the first information used to indicate whether the first device supports beamforming transmission of the first signal as an example, beamforming transmission of the first signal helps to concentrate the energy and / or wireless power of the first signal in a certain direction, thereby improving the efficiency of providing energy and / or wireless power to the second device through the first signal.

[0136] Taking the first information used to indicate a second device powered and / or wirelessly powered by a first device as an example, in some implementations, the first information may carry an identifier of the second device powered and / or wirelessly powered by the first device.

[0137] In this application embodiment, the first information is not limited. In some implementations, the first information can also be used to indicate whether the first device supports receiving and / or transmitting wake-up signals based on PPDU transmission. For example, the first information is used to indicate whether the first device supports transmitting PPDUs carrying wake-up signals on 2.4 GHz. In other implementations, the first information can be used to indicate whether the first device supports receiving and / or transmitting downlink PPDUs. For example, the first information is used to indicate whether the first device supports transmitting downlink PPDUs on 2.4 GHz. In still other implementations, the first information can be used to indicate the maximum transmit power supported by the first device.

[0138] In some scenarios, the aforementioned first information may be actively sent by the first device to the network device, or the first information may be requested based on a second request sent by the network device. That is to say, the above method further includes: the network device sending a second request to the first device, the second request being used to request the capabilities of the first device related to the first signal, or in other words, the second request being used to request the first information from the first device.

[0139] In some implementations, the network device can also acquire the capabilities of the second device. That is, the above method also includes: the network device sending a fourth request to the second device, the fourth request being used to request the capabilities of the second device; and / or the network device receiving the capabilities of the second device sent by the second device.

[0140] In some implementations, the capabilities of the second device are correlated with its energy output; for example, the capabilities of the second device are used to indicate the efficiency of its energy and / or wireless power harvesting. This will be explained below with reference to Figure 5.

[0141] For ease of understanding, a schematic flowchart illustrating the reporting capabilities of the first and second devices to the network device in this embodiment of the application is provided below with reference to Figure 5. It is assumed that the first device is an exciter, the second device is an AMP no-AP STA, and the network device is an AP. The method shown in Figure 5 includes steps S510 to S540. It should be understood that Figure 5 mainly illustrates the relevant process; for information regarding the process, please refer to the above description.

[0142] In step S510, the AP sends a second request to the exciter, which requests the first information. For a description of the second request, please refer to the above text.

[0143] In step S520, the actuator sends first information to the AP. In some implementations, the first information is also called a capability report; a related introduction to the first information can be found above.

[0144] In step S530, the AP sends a fourth request to the AMP no-AP STA, which requests the capability of the second device.

[0145] In step S540, the AMP no-AP STA sends the capabilities of the second device to the AP. For details on the capabilities of the second device, please refer to the above text.

[0146] It should be noted that the scheme shown in Figure 5 can be understood as the initialization process of WPT, that is, the initialization process of the scheme shown in Figure 6. Accordingly, the first information sent by the exciter and the capabilities of the second device reported by the second device are also called initial parameters.

[0147] Figure 6 is a schematic flowchart illustrating how a first device provides energy and / or wireless power to a second device in an embodiment of this application. It is assumed that the first device is an exciter, the second device is an AMP no-AP STA, and the network device is an AP. The method shown in Figure 6 includes steps S610 to S660. It should be understood that Figure 6 mainly describes the relevant process; for more information about the process, please refer to the above description.

[0148] In step S610, the AMP no-AP STA sends a third request to the AP, which is used to provide power and / or wireless power to the second device.

[0149] In step S620, the AP sends a first request to the exciter. The first request is used to request the first device to provide energy and / or wireless power to the second device. The first request carries control information.

[0150] In step S630, the exciter sends a response message to the AP in response to the first request, indicating whether to accept or refuse to provide energy and / or wireless power to the second device.

[0151] In step S640, the actuator sends WPT signal 1 to the AMP no-AP STA based on the control information.

[0152] In step S650, the AMP no-AP STA communicates with the AP based on the WPT signal (referred to as "Tx / Rx"). For example, the AMP no-AP STA sends a signal to the AP based on the WPT signal, and / or the AMP no-AP STA receives a signal sent by the AP based on the WPT signal.

[0153] In step S660, the exciter sends WPT signal 2 to the AMP no-AP STA based on the control information.

[0154] It should be noted that in the scheme shown in Figure 6, the exciter sending WPT and / or Tx / Rx of the AMP no-AP STA (e.g., step S640) can be repeated. During this repetition process, a WPT request from the AP (i.e., the first request) and a response from the exciter can be inserted as needed to reconfigure the control information. Additionally, the process of the AMP no-AP STA sending a third request can also be inserted multiple times in the scheme shown in Figure 6.
