These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of the embodiments of the present disclosure, the first indication information may also be referred to as the second indication information, and similarly, the second indication information may also be referred to as the first indication information. Depending on the context, the words "if" and "if" as used herein may be interpreted as "at the time of" or "when" or "in response to determining".

[0143] The embodiments of the present disclosure are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present disclosure, and should not be understood as limiting the present disclosure.

[0144] In some embodiments, the first device is a terminal, the second device is a network device, and the fourth device is a charging node.

[0145] As shown in Figure 1A, the method provided in the embodiment of the present disclosure can be applied to a wireless communication system 100, which may include a terminal 101, a network device 102, and a charging node 103. It should be noted that the wireless communication system 100 may also include other devices, and this application does not limit the devices included in the wireless communication system 100.

[0146] The wireless communication system 100 is applicable to both low-frequency and high-frequency scenarios. Application scenarios of the wireless communication system 100 include, but are not limited to, long-term evolution (LTE) systems, LTE frequency division duplex (FDD) systems, LTE time division duplex (TDD) systems, worldwide interoperability for microwave access (WiMAX) communication systems, cloud radio access networks (CRAN) systems, future fifth-generation (5G) systems, new radio (NR) communication systems, future evolved public land mobile networks (PLMN) systems, and Internet of Things systems.

[0147] Terminal 101 may be a terminal, an access terminal, a terminal unit, a terminal station, a mobile station (MS), a remote station, a remote terminal, a mobile terminal, a wireless communication device, a terminal agent, an Internet of Things terminal, etc. The terminal 101 may have a wireless transceiver function, and may communicate with one or more network devices of one or more communication systems (such as wireless communication) and receive network services provided by the network devices, where the network devices include but are not limited to the network device 102 shown in the figure. Terminal 101 may also be an Internet of Things terminal. Among them, the complexity, manufacturing cost and maintenance cost of the Internet of Things terminal are lower than those of ordinary terminals. The Internet of Things terminal may not be equipped with a battery and is powered by receiving electromagnetic signals. The Internet of Things terminal may also have a battery with a small amount of electrical storage function, which does not require manual charging, but obtains battery energy from the outside, for example, by obtaining battery energy from external electromagnetic waves, thermal energy, kinetic energy, etc.

[0148] The charging node 103 may be a third device configured to send an excitation signal to the first device. In one example, the third device is a continuous wave node (CWN), and the excitation signal is a continuous electromagnetic wave.

[0149] The charging node 103 may also be an energy source node (ESN).

[0150] In some embodiments, different terminals 101 have different capabilities. For example, different terminals 101 may have different types and working modes, and their power acquisition and storage capabilities may also be different.

[0151] The capabilities of the first type of terminal (which may be referred to as device A) include: being unable to actively send uplink signals.

[0152] In some possible embodiments, the first type of terminal (which may be referred to as device A) may or may not have energy storage capability.

[0153] In some possible embodiments, the first type of terminal (which may be referred to as device A) can only passively send uplink signals.

[0154] For example, after receiving the excitation signal sent by the network device, the first type of terminal uses the backscattering working mode to send an uplink signal. If the first type of terminal does not receive the excitation signal sent by the network device, it cannot actively send an uplink signal.

[0155] The capabilities of the second type of terminal (which may be referred to as device B) include: having energy storage capability and being unable to actively send uplink signals.

[0156] The capabilities of the third type of terminal (which may be referred to as device C) include: energy storage capability and the ability to actively send uplink signals.

[0157] In one example, the third type of terminal has a radio frequency (RF) module that actively sends uplink signals.

[0158] Of the three types of terminals mentioned above, Type 3 terminals have the strongest capabilities and the highest cost. Type 1 terminals have the weakest capabilities and the lowest cost. Furthermore, since Type 1 and Type 2 terminals can only operate in backscatter mode and cannot actively transmit uplink signals, their supported coverage range is smaller. However, the power consumption of Type 1 and Type 2 terminals in their operating mode is lower than that of Type 3 terminals.

[0159] In some embodiments, the terminal 101 is an Ambient-IoT.

[0160] In some embodiments, AmbientIoT uses backscatter communications technology, which is one of the key technologies for building a green, energy-saving, low-cost, and flexibly deployable future Internet of Things, and is an important means to achieve "intelligent connection of all things".

[0161] Backscatter communication utilizes the principle of RF signal backscattering to create an extremely low-power modulation and transmission technology. Since RF signals are partially reflected when they reach surfaces, the transmitting node adjusts the matching between the receiving antenna and the impedance based on the intended transmission information, enhancing the reflection of the incoming RF signal. The node then modulates the acquired sensory data onto the reflected signal, completing the data transmission.

[0162] During backscatter communication, a terminal receives a radio frequency signal. Its internal circuitry modulates the incoming electromagnetic wave to transmit the information, using methods such as load impedance modulation. The modulated electromagnetic wave carrying the information is then transmitted. Information can be modulated using a variety of methods, including amplitude shift keying (ASK), frequency shift keying (FSK), and phase shift keying (PSK).

[0163] For terminals using backscatter communication, the process is as follows: the network device sends a downlink command to the terminal. After receiving the downlink command, the terminal sends a corresponding response message to the network device or performs the corresponding operation. While sending the response message, the terminal needs the CWN to provide it with electromagnetic waves for reflection. The CWN can be a separate node, a base station, or an intermediate node (such as a UE) that communicates with the terminal. Continuous electromagnetic waves (CW) generally have a constant amplitude. The frequency of the electromagnetic wave reflected by the terminal can be exactly the same as the frequency of the continuous electromagnetic wave, or there can be some offset. The value of this offset depends on the hardware characteristics of the terminal. The offset can be a fixed value, one of multiple fixed values ​​if the terminal hardware supports it, or a dynamically adjustable value.

[0164] Compared with other communication technologies, backscatter communication has the following advantages: it does not require complex RF structures, reduces the use of devices such as power amplifiers, high-precision crystal oscillators, duplexers, and high-precision filters, and does not require complex baseband processing. Therefore, backscatter communication technology can simplify terminal design and significantly reduce terminal node costs.

[0165] In some embodiments, as shown in FIG1B , the IoT terminal may have four types of links. Specifically:

[0166] The first link is the downlink for transmitting downlink data, which can be called link1;

[0167] The second link is the uplink for transmitting uplink data and can be called link2;

[0168] The third link is used to receive continuous electromagnetic waves and can be called link 3;

[0169] The fourth link is a link for receiving charging signals, which may be referred to as link 4.

[0170] The four nodes involved in these four links can be the same node, or two, three, or four separate nodes.

[0171] For example, the node connected by the first link is a downlink signal node (DSN), the node connected by the second link is an uplink receiver (UR), the node connected by the third link is a continuous electromagnetic wave node (CWN), and the node connected by the fourth link is an energy source node (ESN).

[0172] The fourth link (Link 4) may be controlled by the network. For example, network device 102 can control the ESN to enable or disable charging for the terminal. The energy in the fourth link (Link 4) can come from electromagnetic waves or non-electromagnetic charging signals. In this case, it can be considered that the ESN can better cooperate with network scheduling and other functions to ensure terminal charging while minimizing the impact on terminal communication.

[0173] The fourth link (Link 4) may also be uncontrolled by the network. In other words, the terminal can flexibly collect energy based on its capabilities and energy sources in the actual environment. For example, it can collect energy from electromagnetic waves or non-electromagnetic waves that are not controlled by the network. In this case, the fourth link (Link 4) can be considered non-existent.

[0174] The following embodiments in this disclosure are all applicable to the first prerequisite, which is: the premise that the charging signal is controlled by the network device. For example: the network device 102 can control the ESN to turn on or off the charging of the terminal, and the energy can come from electromagnetic wave energy or non-electromagnetic wave energy. If it is electromagnetic wave or non-electromagnetic wave energy that is not controlled by the network, it is not within the scope of discussion in this article. In some possible embodiments, as long as the terminal can receive electromagnetic waves greater than a certain power (the specific functional threshold value is related to the performance of the energy collection circuit), it can be charged through the electromagnetic wave.

[0175] The following embodiments of the present disclosure are all applicable to the second prerequisite, which is that a topology suitable for the terminal has been established, that is, a suitable DSN, UR, CWN, and ESN have been matched for the terminal.

[0180] In some embodiments, the first configuration information is used to configure a first time-frequency resource, and the first time-frequency resource is used by the terminal 101 to send the first information to the network device.

[0181] In some embodiments, the network device 102 sends the first configuration information in a broadcast manner.

[0182] In some embodiments, the network device 102 sends the first configuration information to the terminal 101 in a unicast manner.

[0183] In some embodiments, the network device 102 sends the first configuration information to the terminal 101 via the DSN in a unicast manner.

[0184] Optionally, the first time-frequency resource is a periodic time-frequency resource.

[0185] Optionally, the first time-frequency resource is not a periodic time-frequency resource.

[0186] Step S2102 , the terminal 101 sends first information to the network device 102 .

[0187] In some embodiments, after receiving the first configuration information, the terminal 101 may determine whether to send the first information.

[0188] In some embodiments, the first information is used by the network device 102 to determine whether to charge the terminal 101.

[0189] In some embodiments, the first information is used to request the network device 102 to charge the terminal 101.

[0190] In one example, when the first information is used to request the network device 102 to charge the terminal 101, the first information can be called first request information.

[0191] In some embodiments, when the remaining energy is less than or equal to a first threshold, the terminal 101 sends first information to the network device 102 , where the first information is first request information.

[0192] In some embodiments, terminal 101 does not periodically send the first information.

[0193] In some embodiments, the first information includes energy information of the terminal.

[0194] In some embodiments, when the first information includes energy information of the terminal, the first information may be referred to as second request information.

[0195] In one example, the second request information is auxiliary information, and the network device 102 is prompted to refer to the auxiliary information.

[0196] In some embodiments, the energy information includes at least one of the following:

[0197] Information on remaining energy;

[0212] In some embodiments, when receiving unicast first configuration information, the first information may or may not include the identifier of terminal 101, that is, the first information does not necessarily include the identifier of terminal 101. It is understandable that when the first configuration information is unicast, the first time-frequency resource is terminal-specific, and the network device can determine terminal 101 through the terminal-specific first time-frequency resource. In addition, when the first configuration information is unicast, there may be a situation where multiple terminals are configured with the same first time-frequency resource, so the first information may also include the identifier of terminal 101.

[0213] In some embodiments, terminal 101 is a first type terminal (which may be referred to as device A) with clock maintenance capability.

[0238] In some embodiments, the network device 102 updates the second duration during a period when the charging node does not send a charging signal to the terminal.

[0239] In some embodiments, the network device 102 sends second notification information to the charging node 103 before sending downlink data information to the terminal 102 .

[0240] In some embodiments, the network device 102 sends second notification information to the charging node 103 before the terminal 102 sends uplink data.

[0241] In step S2105 , the charging node 103 performs charging processing.

[0242] In some embodiments, when the charging node 103 continues to charge the terminal 101 before step S2105, and receives the first notification information sent by the network device 102, and the first notification information does not correspond to the first duration, it still continues to charge the terminal 101.

[0245] In one example, the charging node 103 needs to continue charging the terminal 101 by default until the second notification information is received.

[0246] In some embodiments, when the charging node 103 continues to charge the terminal 101 before step S2105, it receives a second notification message sent by the network device 102, and when the second notification message corresponds to a second time period, it does not charge the terminal 101 within the second time period, and continues to charge the terminal 101 after the second time period ends.

For example, step S2102 may be implemented as an independent embodiment, step S2102 and step S2103 may be implemented as independent embodiments, step S2102, step S2103, and step S2104 may be implemented as independent embodiments, and step S2102, step S2103, step S2104, and step S2105 may be implemented as independent embodiments, but are not limited thereto.

[0261] In some embodiments, step S2101, step S2103, and step S2105 are optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0262] In some embodiments, the execution order of different steps in steps S2101 to S2105 can be changed.

[0263] FIG2B is an interactive diagram of a charging method according to an embodiment of the present disclosure. As shown in FIG2B , the method includes the following steps:

[0264] Step S2201: The network device 102 sends first configuration information to the terminal 101.

[0265] The optional implementation of step S2201 is the same as the optional implementation of step S2101, refer to step S2101.

[0266] Step S2202 : The network device 102 sends second configuration information to the charging node 103 .

[0267] In some embodiments, the second configuration information is used to configure the charging node 103 to send a charging signal to the terminal 101, or is called the second configuration information is used to configure the charging mode (pattern), wherein the second configuration information includes at least one of the following parameters: the second period, the duration of sending the charging signal in the second period (onduration), the duration of not sending the charging signal in the second period (offduration), the time domain offset (offset), and the power of the charging signal.

[0268] In an example, in the second configuration information, the second period is 1280 ms, the sending duration (onduration) in the second period is 640 ms, the non-sending duration (offduration) in the second period is 640 ms, and the time domain offset (offset) is 0 ms.

[0269] In one example, the time domain offset is 40ms, the second period is Tms, and the starting positions of the second periods are 40ms, 40+Tms, 40+2Tms, and so on.

[0270] In some embodiments, after receiving the second configuration information, the charging node 103 starts charging the terminal, that is, charging the terminal according to the second configuration information, or, described as, charging the terminal according to the charging mode of the second configuration information.

[0271] In some embodiments, after receiving the second configuration information, the charging node 103 does not start charging the terminal, but only saves the second configuration information.

[0272] In some embodiments, the network device 102 determines the parameters in the second configuration information based on the auxiliary information in the first information.

[0273] In one example, the network device 102 determines the power of the charging signal in the second configuration information according to the remaining power in the first information.

[0274] In one example, the network device 102 determines the duration of sending the charging signal within the second period in the second configuration information according to the remaining power in the first information.

[0275] Step S2203 , the terminal 101 sends first information to the network device 102 .

[0276] The optional implementation of step S2203 is the same as the optional implementation of step S2102, refer to step S2102.

[0277] In step S2204 , the network device 102 determines whether to charge the terminal 101 based on the first information.

[0278] The optional implementation of step S2204 is the same as the optional implementation of step S2103, refer to step S2103.

[0279] In step S2205 , the network device 102 sends notification information to the charging node 103 .

[0280] The optional implementation of step S2205 is the same as the optional implementation of step S2104, refer to step S2103.

[0281] In step S2206, the charging node 103 performs charging processing.

[0282] In some embodiments, when the charging node 103 has used the charging mode (i.e., the charging mode configured by the second configuration information) to charge the terminal, the processing method for receiving different notification information is as follows:

[0283] When the first notification information sent by the network device 102 is received and the first notification information does not correspond to the first duration, the charging node 103 still uses the charging mode to charge the terminal, or continues to charge the terminal in the current cycle and resumes using the charging mode to charge the terminal 101 at the beginning of the next cycle.

[0284] When the first notification information sent by the network device 102 is received and the first notification information corresponds to the first duration, the terminal is continuously charged within the first duration, and the charging mode is continued to be used to charge the terminal after the first duration ends. Alternatively, the charging node 103 uses the charging mode to charge the terminal within the first duration, and continues to use the charging mode to charge the terminal after the first duration ends.

[0285] When the second notification information sent by the network device 102 is received and the second notification information does not correspond to the second duration, the charging node 103 does not charge the terminal 101 in the current cycle, and resumes using the charging mode to charge the terminal in the next cycle, or does not charge the terminal 101 until the first notification information is received.

[0286] The network device 102 receives the second notification information sent by the network device 102, and the second notification information corresponds to the second duration. The charging node 103 does not charge the terminal 101 within the second duration. After the second duration ends, the charging mode is restored to charge the terminal 101.

[0287] In one example, in the second configuration information, the second period is 1280 ms, the sending duration (onduration) within the second period is 640 ms, the non-sending duration (offduration) within the second period is 640 ms, and the time domain offset (offset) is 0 ms. The time period corresponding to the sending duration (onduration) within the second period is called the first time period, and the time period corresponding to the non-sending duration (offduration) within the second period is called the second time period.

[0288] The ESN periodically charges the terminal 101 according to the second configuration information. Specifically, the ESN sends a charging signal during a first period and does not send a charging signal during a second period.

[0289] The network device 102 sends a first notification message to the ESN, and the first notification message does not correspond to the first duration. Then, after receiving the first notification message, the ESN will start sending a charging signal to continuously charge the terminal until the end of the current cycle, and at the beginning of the next cycle, it will resume using the charging mode to charge the terminal 101.

[0290] The network device 102 can send a first notification message to the ESN, and the first notification message corresponds to a first duration of T1. Then, after receiving the first notification message, the ESN will start sending a charging signal and maintain the T1 duration. After the T1 duration ends, it will resume using the charging mode to charge the terminal 101. Alternatively, the charging node 103 uses the charging mode to charge the terminal within the T1 duration, and continues to use the charging mode to charge the terminal after the T1 duration ends.

[0291] The network device 102 sends a second notification message to the ESN, and the second notification message does not correspond to the second duration. The ESN will stop sending the charging signal after receiving the second notification message until the end of the current cycle, and resume using the charging mode to charge the terminal 101 at the beginning of the next cycle, or will not charge the terminal until the first notification message is received.

[0292] The network device 102 sends a second notification message to the ESN, and the second duration is T2. The ESN will stop sending the charging signal after receiving the second notification message and maintain the duration of T2. After T2 ends, it will resume using the charging mode to charge the terminal 101.

[0293] In some embodiments, when the charging node 103 does not charge the terminal, the processing method of receiving different notification information is as follows:

[0294] When the first notification information sent by the network device 102 is received and the first notification information does not correspond to the first duration, the charging mode is started to charge the terminal.

[0295] When the first notification information sent by the network device 102 is received and the first notification information corresponds to the first duration, the terminal is charged using the charging mode during the first duration, and charging of the terminal is stopped after the first duration ends.

[0296] The second notification information sent by the network device 102 is received, and when the second notification information does not correspond to the second duration, the terminal 101 continues to not be charged.

[0297] The second notification information sent by the network device 102 is received, and the second notification information corresponds to the second duration, and the terminal 101 continues to remain uncharged.

[0298] In some embodiments, when the charging node 103 is a CWN, the charging signal is a continuous electromagnetic wave.

[0299] In some embodiments, when the charging node 103 is an ESN, the charging signal is an energy signal.

[0300] The disclosed embodiments are applicable to the third type of terminal (which may be referred to as device C), the second type of terminal with clock maintenance capability (which may be referred to as device B), and the first type of terminal with clock maintenance capability (which may be referred to as device A).

[0301] The charging method involved in the embodiment of the present disclosure may include at least one of steps S2201 to S2206. For example:

[0302] Step S2201 and step S2202 may be implemented as independent embodiments;

[0303] Step S2203 may be implemented as an independent embodiment;

[0309] In some embodiments, the execution order of different steps in steps S2201 to S2206 can be changed.

[0310] FIG2C is an interactive diagram of a charging method according to an embodiment of the present disclosure, wherein the charging node 103 is a CWN. As shown in FIG2C , the method includes the following steps:

[0311] In step S2301 , the CWN sends continuous electromagnetic waves to the terminal 101 , and the terminal 101 sends first information to the network device 102 .

[0312] In some embodiments, the CWN sends continuous electromagnetic waves to the terminal 101 via the second time-frequency resource.

[0313] In some embodiments, the second time-frequency resource is semi-statically configured by the network device 102 .

[0314] In some embodiments, the second time-frequency resource is dynamically indicated by the network device 102 .

[0315] In some embodiments, the terminal 101 sends the first information using the excitation signal based on backscatter technology.

[0316] Optionally, the first information is first request information, or second request information.

[0317] In some embodiments, terminal 101 is a second type terminal (which may be referred to as device B) that does not have the capability of maintaining a clock, or a first type terminal (which may be referred to as device A) that does not have the capability of maintaining a clock.

[0318] Step S2302: The network device 102 sends a second notification message to the CWN.

[0319] In some embodiments, the second notification information is used to notify the charging node 101 to stop sending the charging signal to the terminal 101.

[0320] In some embodiments, the second notification information corresponds to a second time period, and the charging node 103 does not send a charging signal to the terminal 101 during the second time period.

[0321] Step S2303: The CWN performs charging processing according to the second notification information.

[0322] In some embodiments, after receiving the second notification information sent by the network device 102 , the charging node 103 does not send a charging signal to the terminal 101 .

[0323] In some embodiments, the charging node 103 is turned on by default, that is, the charging node 103 continues to charge the terminal 101 until the second notification information sent by the network device 102 is received.

[0324] In some embodiments, the charging node 103 receives the second notification information sent by the network device 102, and when the second notification information does not correspond to the second duration, the charging node 103 does not send charging information to the terminal 101 in the current cycle, and resumes using the second configuration information to send a charging signal to the terminal in the next cycle.

[0325] In some embodiments, charging node 103 receives a second notification message sent by network device 102, and the second notification message corresponds to a second duration. Charging node 103 does not send a charging signal to terminal 101 during the second duration. After the second duration ends, charging node 103 resumes sending a charging signal to terminal 101 using the second configuration information, or continues to send a charging signal to terminal 101.

[0326] FIG2D is an interactive schematic diagram of a charging method provided according to an embodiment of the present disclosure. As shown in FIG2D , the method includes the following steps:

[0327] Step S2401 , the network device 102 sends downlink data information to the terminal 101 .

[0328] Step S2402: Terminal 101 is charged through downlink data information.

[0329] In some embodiments, the time domain symbol corresponding to the setting information includes a high level signal and a low level signal.

[0330] In some embodiments, the terminal 101 uses the high-level signal to charge during a period corresponding to the high-level signal (which may be referred to as a high-level period).
