[0160] FIG1a is a schematic diagram showing the architecture of a communication system according to an embodiment of the present disclosure.

[0161] As shown in FIG. 1 a , a communication system 100 includes a terminal 101 , a first device 102 , and a second device 103 .

[0162] In some embodiments, terminal 101 may be an Ambient-IoT terminal or device. Terminal 101 may not be equipped with a battery and may be excited and powered by received electromagnetic signals; or it may be equipped with a battery with a small amount of electrical storage capacity and obtain energy from the battery by obtaining external electromagnetic waves, thermal energy, kinetic energy, etc.

[0163] In some embodiments, the power acquisition and storage capabilities of the terminal 101 vary depending on the type and operating mode of the terminal 101. For example, the types of the terminal 101 may include the following:

[0164] Device 1 (device 1): cannot perform independent signal generation or amplification. For example, device 1 uses a backscattering mode or backscattering communication and does not have the ability to amplify downlink (DL) signals and / or uplink (UL) signals.

[0165] Device 2a: Has energy storage capabilities but cannot independently generate signals. For example, device 2a uses backscattering and can use stored energy for DL ​​and / or UL signal amplification.

[0166] Device 2b: has energy storage capabilities and can independently generate signals, such as a radio frequency (RF) module that actively sends signals.

[0167] Among the aforementioned terminal 101 types, device 2b has the strongest capabilities and the highest terminal cost. Device 1 and device 2a have weaker capabilities and lower terminal costs. Furthermore, because devices 1 and 2a require backscattering and cannot actively transmit signals, their supported coverage range is smaller. However, the power consumption of device 1 or 2a in this operating mode is lower than that of device 2b.

[0168] In some embodiments, the terminal 101 includes, for example, a mobile phone, a wearable device, an Internet of Things device, a car with communication function, a smart car, a tablet computer, a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, and at least one of a wireless terminal device in a smart home, but is not limited thereto.

[0169] In some embodiments, in an Ambient-IoT scenario, as shown in Figure 1b , the communication system 100 may further include a continuous wave node (CWN) 104. CWN 104 is configured to transmit continuous electromagnetic waves (CWs), which terminal 101 can use to transmit uplink information based on backscatter. CWN 104 can implement an excitation function, enabling device 1 and device 2a to perform uplink transmission based on backscatter. Furthermore, CWs can serve as an energy source (ES), providing energy to terminal 101, which can receive and store CWs.

[0170] In some embodiments, first device 102 may be an Energy Source Node (ESN) 102, configured to provide energy to terminal 101. Specifically, ESN 102 is configured to provide energy to terminal 101. For example, ESN 102 may function as both device 2a and device 2b. Due to the limited energy storage capabilities of device 2a, ES signals other than CW may not be defined for device 2a. Alternatively, ES signals may also be used for device 2a.

[0171] In some embodiments, in a downlink transmission scenario, second device 103 may be a network device or a relay device, wherein the network device or relay device may serve as a downlink signaling node (DSN), denoted as DSN 105. The network device may be a base station, and the relay device may be a relay UE. DSN 105 is configured to transmit downlink information or indication information. DSN 105 may send signaling to terminal 101 to trigger uplink transmission by terminal 101.

[0172] In some embodiments, in an uplink transmission scenario, the second device 103 may be an uplink receiver (UR), denoted as UR 106. UR 106 may be a terminal other than terminal 101 or user equipment (UE), configured to receive uplink information sent by Ambient-IoT terminal 101. For example, the UR 106 may receive uplink information sent by terminal 101 via backscatter communication, or may receive uplink information actively transmitted by terminal 101.

[0173] In some embodiments, the network device can be configured to implement at least one of the following functions: DSN 105 , CWN 104 , UR 106 , ESN 102 . Alternatively, the network device can control at least one of the following nodes: DSN 105 , CWN 104 , UR 106 , ESN 102 .

[0174] In some embodiments, as shown in Figure 1b, the Ambient-IoT communication system may include four links, for example: link 1 for transmitting downlink information, link 2 for receiving uplink information, link 3 for sending CW, and link 4 for sending charging signals.

[0175] In some embodiments, link 4 may be controlled by the network. For example, the network may control ESN 102 to enable or disable charging of terminal 101. The energy provided by ESN 102 may come from electromagnetic waves or non-electromagnetic waves. In this case, ESN 102 can better coordinate with network scheduling and other functions to ensure that terminal 101 is charged while minimizing the impact on terminal 101's communications. Alternatively, ESN 102 may not be controlled by the network. In other words, terminal 101 may flexibly collect energy based on its capabilities and the energy sources in its actual environment. For example, it may collect electromagnetic or non-electromagnetic energy that is not controlled by the network, without a specific ESN 102 node. In this case, link 4 may be considered non-existent.

[0176] In some embodiments, the nodes involved in the four links in the above embodiments, such as DSN 105, CWN 104, ESN 102, and UR 106, can be independently configured, or can be the same node or device, or two, three, or four of them can be configured as one node or device. For example, in some embodiments, link 4 can be omitted or non-existent.

[0177] In some embodiments, the functions of the above-mentioned different nodes can be implemented or supported by a single device. For example, a single device can support the functions of multiple nodes or all of the above-mentioned nodes. Alternatively, a single device can correspond to a node with only one of the above-mentioned functions. Network device 102 can coordinate the behavior of the above-mentioned different nodes, such as CWN 104, ESN 102, and UR 106, to support effective communication with terminal 101.

[0178] In some embodiments, the network device may include at least one of an access network device and a core network device.

[0179] In some embodiments, the access network device is, for example, a node or device that accesses a terminal to a wireless network. The access network device may include an evolved NodeB (eNB), a next generation evolved NodeB (ng-eNB), a next generation NodeB (gNB), a node B (NB), a home node B (HNB), a home evolved nodeB (HeNB), a wireless backhaul device, a radio network controller (RNC), a base station controller (BSC), a base transceiver station (BTS), a base band unit (BBU), a mobile switching center, a base station in a 6G communication system, an open base station (Open RAN), a cloud base station (Cloud RAN), a base station in other communication systems, and at least one of an access node in a wireless fidelity (WiFi) system, but is not limited thereto.

[0180] In some embodiments, the number of devices or nodes in FIG. 1 a and FIG. 1 b is for illustration only, and in actual applications, multiple devices or nodes may be used.

[0181] In some embodiments, the technical solution of the present disclosure can be applied to the Open RAN architecture. In this case, the interfaces between or within the access network devices involved in the embodiments of the present disclosure can be transformed into internal interfaces of the Open RAN, and the processes and information interactions between these internal interfaces can be implemented through software or programs.

[0182] In some embodiments, the access network device can be composed of a centralized unit (CU) and a distributed unit (DU), where the CU can also be called a control unit. The CU-DU structure can be used to split the protocol layer of the access network device, with the functions of some protocol layers centrally controlled by the CU, and the functions of the remaining part or all of the protocol layers distributed in the DU, which is centrally controlled by the CU, but is not limited to this.

[0183] In some embodiments, the core network device can be a device including one or more network elements, or it can be multiple devices or device groups, each including all or part of one or more network elements. The network element can be virtual or physical. The core network includes, for example, at least one of the Evolved Packet Core (EPC), the 5G Core Network (5GCN), and the Next Generation Core (NGC). Alternatively, the core network device refers to a network element with a specific function, such as the Access Management Function (AMF), the Service Management Function (SMF), etc.

Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0188] When the terminal 101 is device 1 (device 1), the circuit system architecture can be referred to as shown in Figure 1c. The terminal 101 includes a clock generator, logic circuits (Base Band logics, BB logics) and memory. It also includes an antenna, a link for charging, a link for uplink transmission and a link for downlink reception.

[0189] Among them, the logic circuit may include a decoder, a controller and an encoder.

[0190] Terminal 101 is device 2a, which has an RF receiver. The circuit system architecture is shown in Figure 1d. Terminal 101 includes a clock generator, logic circuits, and memory. It also includes an antenna, a link for charging, a link for uplink transmission, and a link for downlink reception.

[0191] Among them, the logic circuit may include a decoder, a controller and an encoder.

[0192] In the architecture of Figure 1c or Figure 1d, terminal 101 uses a single antenna for charging, downlink reception, and uplink transmission, and a single matching network for charging and downlink reception. In this architecture, terminal 101 cannot simultaneously perform charging, downlink reception, and uplink transmission.

[0193] The embodiments of the present disclosure provide a charging method that can not only provide sufficient energy for a terminal, but also ensure timely downlink reception or uplink transmission.

[0194] Figure 2a is an interactive diagram of a communication processing method according to an embodiment of the present disclosure. As shown in Figure 2a, the present disclosure embodiment relates to a communication processing method, the method comprising:

[0195] Step S2101: The first device 102 sends a charging signal to the terminal 101.

[0196] In some embodiments, the first device 102 may be the node ESN 102 shown in FIG. 1 b .

[0197] In some embodiments, the first device 102 may be the same node as the network device, or a node controlled by the network device, and may charge the terminal 101 according to the control of the network device.

[0198] In some embodiments, the terminal 101 is an Ambient IoT terminal.

[0199] In some embodiments, the terminal 101 receives a charging signal from the first device 102 in the first state.

[0200] In some embodiments, the first state is a charging or waiting-to-charge state.

[0201] In some embodiments, as shown in FIG2c , the terminal 101 switches between different states, wherein the first state can be regarded as a default state or an initial state of the terminal 101 .

[0202] In some embodiments, the charging signal may be an electromagnetic signal, such as a high-power electromagnetic signal.

[0203] In some embodiments, the terminal 101 can obtain energy by receiving a charging signal in the first state.

[0204] Step S2102: When the first condition is met, the terminal 101 switches from the first state to the second state.

[0205] In some embodiments, the second state is a downlink receiving state. When the terminal 101 is in the second state, it can receive downlink information sent by the second device 102, as described in step S2103.

[0206] In some embodiments, as shown in FIG1c or 1d, at the same time, the terminal 101 can select one of the three links for charging, downlink reception, or uplink transmission through a device such as a switch, and implement link switching through the switch.

[0207] In some embodiments, the first condition includes at least one of the following:

[0208] receiving a conversion signal sent by the second device 102;

[0209] The stored energy is greater than or equal to the energy threshold;

[0210] The duration of receiving the charging signal is greater than or equal to the duration threshold.

[0211] In some embodiments, when any of the above conditions is met, the terminal 101 may be converted from the first state to the second state.

[0212] In some embodiments, the conversion signal may be a state transition symbol. When the second device 102 needs to transmit downlink information, it may send a conversion signal to the terminal 101 to indicate that the network device 102 will enter downlink transmission after the conversion signal ends.

[0213] In some embodiments, the conversion signal includes a waveform pattern in the time domain, and the waveform pattern includes periodic high-level symbols and / or low-level symbols.

[0214] The waveform pattern of the transition signal or state transition symbol in the time domain can be specific or set, that is, both the terminal 101 and the second device 102 can determine whether the signal is a transition signal through the waveform pattern in the time domain. For example, in the time domain, the duration or symbol duration of each transition signal consists of a high-level (ON) symbol and a low-level (OFF) symbol, where the length of the ON symbol is 10 microseconds (μs) and the length of the OFF symbol is 10 μs. Within the duration of the transition signal, the ON symbol-OFF symbol cycle can repeat for four cycles.

[0215] In some embodiments, the conversion signal is a zero-power signal.

[0216] The zero-power signal may have a set duration, for example, during the duration or time period corresponding to the conversion signal, the second device 102 does not send a powered signal.

[0217] In some embodiments, the duration of the transition signal is greater than or equal to a first duration, where the first duration is the duration required for the terminal to transition from the first state to the second state. Thus, after receiving the transition signal, the terminal has sufficient time to transition to a new state and perform downlink reception in a timely manner.

[0218] In some embodiments, the duration of the transition signal is defined by a protocol or configured by a network device.

[0219] In some embodiments, the second device 103 may be the node DSN 105 shown in FIG. 1 b , for example, the second device 103 is a network device or a relay device.

[0220] In some embodiments, if the first device 102 and the second device 103 are the same or different, the time interval between the end position of the charging signal and the start position of the downlink information is greater than or equal to the duration of the conversion signal.

[0221] In some embodiments, for example, ESN 102 and DSN 105 are not the same node, that is, the node sending the charging signal is different from the node sending the downlink information. DSN 105 coordinates with ESN 102, or the two nodes are coordinated through a network device, so that the interval between the end position of the charging signal sent by ESN 102 and the start position of the signal sent by DSN 105 is at least the duration of the conversion signal.

[0222] In some embodiments, the energy threshold or the duration threshold is used to indicate that the terminal 101 has obtained sufficient energy and can have sufficient energy to receive data.

[0223] Step S2103 , the second device 102 sends downlink information to the terminal 101 .

[0224] In some embodiments, in combination with the description of the foregoing embodiments, the second device 102 is a network device such as a base station, or a relay device such as a relay UE.

[0225] In some embodiments, the terminal 101 receives downlink information sent by the network device or the relay device, and can perform corresponding operations based on the downlink information.

[0226] In some embodiments, taking a warehouse inventory process (inventory) as an example, the downlink information may include a query (Query) signaling and / or a repeated query (QueryRep) signaling in the inventory process.

[0227] In some embodiments, Query signaling may also be referred to as a Query command, and QueryRep signaling may also be referred to as a QueryRep command. During the inventory process, the network device first sends a Query signaling, then a QueryRep signaling, and may send Query signaling or QueryRep signaling multiple times. In this scenario, terminal 101 may be a radio frequency identification (RFID) tag.

[0228] In the RFID warehouse inventory business model, after receiving a Query signaling, an RFID tag can set a random value counter based on the Q value in the Query signaling, where counter <= Q. If counter = 0, the RFID tag can begin backscattering uplink information, such as RN16 (a 16-bit random number) used to temporarily represent the tag ID. If the counter value is not 0, the RFID tag does not transmit information and waits to receive a QueryRep command. Each time the RFID tag receives a QueryRep command, the counter value is decremented by 1 until the counter value reaches 0, at which point the RFID tag will transition to the reply state and backscatter uplink information. If an ACK is received, the RFID tag confirms successful access. Otherwise, if an invalid ACK is received, an ACK with an erroneous RN16 is received, or if no corresponding command is received within a set period of time, the RFID tag considers the access unsuccessful.

[0229] In some embodiments, the downlink information may also be a command, which may be used to instruct the terminal 101 to perform a write or access operation.

[0230] Step S2104: When the second condition is met, the terminal 101 switches from the second state to the first state.

[0231] In some embodiments, the description of the second state or the first state can refer to the description of the aforementioned embodiments and will not be repeated here.

[0232] In some embodiments, the second condition includes at least one of the following:

[0233] There is no uplink transmission requirement;

[0234] There is no downlink reception requirement;

[0235] The stored energy is less than the energy threshold.

[0236] In some embodiments, the absence of an uplink transmission requirement can be determined based on received downlink information. For example, using the inventory process as an example, if terminal 101 receives a Query signaling or a QueryRep signaling and the counter value has not decremented to 0, terminal 101 determines that an uplink transmission is not necessary, i.e., there is no uplink transmission requirement. For another example, if terminal 101 receives a downlink command indicating a write or access request, terminal 101 determines that an uplink transmission is not necessary.

[0237] In some embodiments, there is no downlink receiving demand, or the second device 102 has no downlink sending demand. When the terminal 101 is in the second state, if the network device or relay device has no further downlink sending demand, that is, the network device or relay device does not need to send information to the terminal 101, then the terminal 101 has no downlink receiving demand.

[0238] In some embodiments, if the energy stored in the terminal 101 is lower than the energy threshold, it indicates that the terminal 101 needs to enter the first state for charging. If it is not charged, the terminal 101 may not have enough energy for subsequent information sending and receiving.

[0239] In some embodiments, the terminal 101 enters the first state to charge and store power.

[0240] In some embodiments, the names of signals, etc. are not limited to the names described in the embodiments, and terms such as "information", "message", "signaling", "report", "configuration", "indication", "instruction", "command", "channel", "parameter", "domain", and "field" can be used interchangeably.

[0244] In some embodiments, terms such as "moment", "time point", "time", and "time position" can be replaced with each other, and terms such as "duration", "period", "time window", "window", and "time" can be replaced with each other.

[0245] In some embodiments, the terms "component carrier (CC)", "cell", "frequency carrier", "carrier frequency" and the like can be used interchangeably.

[0247] In some embodiments, the determination or judgment can be performed by a value represented by 1 bit (0 or 1), or by a true or false value (Boolean value) represented by true or false, or by comparison of numerical values ​​(for example, comparison with a predetermined value), but is not limited thereto.

[0248] In some embodiments, "not expecting to receive" can be interpreted as not receiving on time domain resources and / or frequency domain resources, or as not performing subsequent processing on the data after receiving it; "not expecting to send" can be interpreted as not sending, or as sending but not expecting the recipient to respond to the content sent.

[0249] The method involved in the embodiment of the present disclosure may include at least one of steps S2101 to S2104.

[0250] In some embodiments, the method includes steps S2101 to S2102, and step S2103 or S2104 may be omitted, and may be replaced by one or more steps in different embodiments.

[0251] In some embodiments, the method includes steps S2101 to S2103, and step S2104 may be omitted and may be replaced by one or more steps in different embodiments.

[0252] In some embodiments, the method includes steps S2101 to S2104.

[0253] In some embodiments, reference may be made to other optional implementations described before or after the description corresponding to FIG. 2 a .

[0254] FIG2b is an interactive diagram of a communication processing method according to an embodiment of the present disclosure. As shown in FIG2b, an embodiment of the present disclosure relates to a communication processing method, the method comprising:

[0255] Step S2201: The first device 102 sends a charging signal to the terminal 101.

[0256] In some embodiments, the implementation of step S2201 can refer to the implementation of step S2101 in Figure 2a, and will not be repeated here.

[0257] Step S2202: When the first condition is met, the terminal 101 switches from the first state to the third state.

[0258] In some embodiments, the third state is an uplink sending state. When the terminal 101 is in the third state, it can send uplink information to the second device 102, as described in step S2203.

[0259] In some embodiments, as shown in FIG1c or 1d, at the same time, the terminal 101 can select one of the three links for charging, downlink reception, or uplink transmission through a device such as a switch, and implement link switching through the switch.

[0260] In some embodiments, the second device 102 may be the UR 106 in FIG. 1 b , which may be a network device, or other terminal, or a terminal controlled by the network device.

[0261] In some embodiments, the first condition includes:

[0262] There is an uplink transmission requirement.

[0263] In some embodiments, the terminal 101 may be configured to actively send uplink information. If the terminal 101 determines that it needs to actively send uplink information or an uplink signal, it may be converted from the first state to the third state.

[0264] In some embodiments, the terminal 101 actively sending uplink information may be configured as periodic active sending or aperiodic active sending.

[0265] In some embodiments, the terminal 101 may determine the start time of the uplink transmission according to the instruction of the network device. In the scenario where the start time of the uplink transmission is determined, the terminal 101 may independently determine the time to end charging or transition from the first state to the third state.

[0266] For example, the method further includes receiving an indication message sent by a network device, the indication message being used to indicate a start time for the terminal to transmit uplink information. In some embodiments, terminal 101 receives the indication message. Assuming that the indication message indicates a start time t0 for transmitting uplink information, terminal 101 will terminate charging at time t1 before t0, i.e., terminate receiving the charging signal, and transition to the third state of transmitting uplink information.

[0267] In some embodiments, the time interval between the end position of the charging signal and the start position of sending the uplink information is greater than or equal to a second duration, and the second duration is the duration required for the terminal to transition from the first state to the third state.

[0268] For example, in the above embodiment, the interval between t1 and t0 should be greater than or equal to the second interval.

[0269] In some embodiments, the duration of the interval between t1 and t0 may be defined by a protocol.

[0270] Step S2203 , the terminal 101 sends uplink information to the second device 103 .

[0271] In some embodiments, combined with the description of the foregoing embodiments, the second device 102 is UR 106 .

[0272] In some embodiments, terminal 101 may determine whether to perform uplink transmission based on received downlink information or instructions. For example, in conjunction with the Query signaling and QueryRep signaling in the embodiment of the aforementioned inventory process, when the counter value decreases to 0, terminal 101 transmits uplink information.

[0273] In some embodiments, the terminal 101 may communicate based on a backscattering method. Backscattering or backscatter communications is an extremely low-power modulation and transmission technology that uses the principle of backscattering of radio frequency signals, and is a means to achieve the intelligent connection of all things. In backscattering communications, radio frequency signals such as electromagnetic waves are received by the terminal 101, and the internal circuit of the terminal 101 modulates the information to be transmitted on the basis of the incident electromagnetic wave through load impedance modulation and other methods, and then sends out the modulated electromagnetic wave carrying the information. There are many ways to modulate information, such as amplitude shift keying (ASK), frequency-shift keying (FSK) or phase-shift keying (PSK).

[0274] In some embodiments, for a terminal 101 using a backscatter method, the workflow may include: the network device sends a downlink instruction (such as Query signaling or QueryRep signaling) to the terminal 101, and after receiving the downlink instruction, the terminal 101 sends a corresponding response to the network device or performs a corresponding operation.

[0275] In some embodiments, when terminal 101 transmits uplink information or data to UR 106, it requires an energy source, such as CWN 104, to provide it with a CW for reflection (i.e., link 3 is required). The CW typically has a constant amplitude. The frequency of the electromagnetic wave reflected by terminal 101 can be exactly the same as the CW frequency, or there can be some offset. The offset size depends on the hardware characteristics of terminal 101. For example, the offset may be a fixed value, or, if supported by the hardware of terminal 101, it may support multiple fixed values, or it may be a dynamically adjustable value.

[0276] In some embodiments, for the Ambient-IoT terminal 101, one way to utilize frequency resources is to divide the available spectrum into multiple sub-channels, each sub-channel occupies a fixed bandwidth, and the sub-channels are orthogonal in the frequency domain. The terminal 101 can be instructed by the network to use one or more of the sub-channels to transmit data, or it can select one or more sub-channels to transmit data through a certain algorithm. For the terminal 101 using the backscattering method, the working bandwidth of its antenna is relatively wide, for example, tens of megahertz (Mhz). If the CWN 103 transmits CWs at multiple frequency points within the working bandwidth of the terminal 101, then the terminal 101 will receive CWs at multiple frequency points and backscatter these multiple CWs, that is, the terminal 101 does not have the ability to reflect only the CW of the specific sub-channel it selects. Which uplink sub-channel the terminal 101 can use for uplink transmission actually depends on the frequency and offset capabilities of the CW.

[0277] In some embodiments, the second device 103 receives uplink information sent by the terminal 101.

[0278] Step S2204: When the third condition is met, the terminal 101 switches from the third state to the first state.

[0279] In some embodiments, the description of the third state and the first state can refer to the description of the aforementioned embodiments and will not be repeated here.

[0280] In some embodiments, the third condition includes at least one of the following:

[0281] Uplink transmission is non-periodic;

[0282] Within the third time duration (T2) after the Nth uplink transmission ends, there is no N+1th uplink transmission requirement, and the third time duration is greater than the threshold value;

[0283] There is no downlink reception requirement;

[0284] The uplink transmission is periodic and the transmission period is greater than a fourth time duration (T3), where the fourth time duration is the time duration required for the terminal to transition from the third state to the first state;

[0285] The stored energy is less than the energy threshold.

[0286] In some embodiments, if the uplink transmission is non-periodic, the terminal 101 cannot anticipate the time of the next uplink transmission after performing an uplink transmission, and thus can transition from the third state to the first state.

[0287] In some embodiments, when the uplink transmission is non-periodic, if no new uplink transmission occurs within a third time period after the end of the uplink transmission, the terminal 101 may transition from the third state to the first state.

[0288] In some embodiments, after sending an uplink message, if the terminal 101 does not need to receive downlink information, it can transition from the third state to the first state. For example, if the terminal 101 has sent uplink information and does not need to receive feedback information (such as ACK / NACK confirmation information) sent by the network side, it can transition from the third state to the first state.

[0289] In some embodiments, when the uplink transmission is periodic, when the period>T3, the terminal 101 can enter the first state after performing one uplink transmission.

[0290] In some embodiments, the fourth time duration is greater than or equal to the time duration for the terminal to switch from the third state to the first state, or the fourth time duration is greater than the time duration for the terminal to switch from the third state to the first state, to ensure that the terminal 101 has sufficient time to charge.

[0291] In some embodiments, if the energy stored in the terminal 101 is lower than the energy threshold, it indicates that the terminal 101 needs to enter the first state for charging. If it is not charged, the terminal 101 may not have enough energy for subsequent information sending and receiving.

[0292] In some embodiments, the terminal 101 enters the first state to charge and store power.

[0332] In an embodiment of the present disclosure, a method for wireless charging in an ambient IoT network is provided. In this method, by flexibly switching between charging and downlink reception or uplink transmission, both charging and downlink reception and uplink transmission are ensured. To facilitate understanding of the embodiments of the present disclosure, some examples are listed below:

[0333] Example 1:

[0334] As shown in FIG2c , the states defining the UE behavior include: state 1: charging / waiting for charging, state 2: receiving signals sent by the DSN, and state 3: sending signals to the UR.

[0335] In some embodiments, state 1 corresponds to the first state of the aforementioned embodiment, state 2 corresponds to the second state of the aforementioned embodiment, and state 3 corresponds to the third state of the aforementioned embodiment.

[0336] Example 2:

[0337] Based on Example 1, the default state of the device is state 1. In other words, the initial state of the device is state 1.

[0338] In some embodiments, Device corresponds to the terminal 101 of the aforementioned embodiment.

[0339] Example 3:

[0340] Based on Example 1 or Example 2, this example describes the transition from State 1 to State 2. State 1 can transition to State 2 when any of the following conditions are met:

[0341] Condition 1: If the device receives a state transition symbol, it transitions from receiving charging signals to receiving downlink signals. If the network wants to send a downlink signal to the device, a state transition symbol must precede the downlink signal. This state transition symbol indicates that the network device will enter the downlink transmission state after the state transition symbol ends.

[0342] I. The state transition symbol can be a time domain symbol with a specific waveform in the time domain, such as an on-off pattern symbol with a specific symbol duration in the time domain (for example, the on symbol length is 10us, the off symbol length is 10us, and the on-off pattern is repeated for 4 cycles);

[0343] Ii. The state transition symbol can also be a period of zero power symbols, that is, during the state transition symbol period, the network does not send any power signal;

[0344] iii. The duration T of the state transition symbol is defined by the protocol. T>=the transition time required for the device to switch to downlink reception;

[0345] If the ESN and DSN sending the charging signal are not the same node, coordination is required between the ESN and DSN nodes. The end position of the charging signal sent by the ESN must be separated from the start position sent by the DSN by at least the duration T of the state transition symbol.

[0346] Condition 2: If the device storage power reaches the threshold, the state transition is performed.

[0347] Condition 3: If the duration for which the device receives the charging signal reaches a threshold, the device undergoes a state transition.

[0348] In some embodiments, only one of the above conditions 1, 2, or 3 needs to be met.

[0349] Example 4:

[0350] Based on any of the above examples, this example describes the transition from state 2 to state 1. State 2 can transition to state 1 when any of the following conditions are met:

[0351] Condition 1: After receiving a downlink signal, if the device does not need to send an uplink signal, it transitions to state 1. For example, during an inventory, if the device receives a query or queryRep command but its Q value has not yet decreased to 0, the device does not need to send an uplink signal. Alternatively, if the device receives a downlink command (such as write or access), it does not need to send an uplink signal.

[0352] Condition 2: The device's stored power level is below the threshold (failure to recharge the device may result in insufficient energy for subsequent information transmission and reception).

[0353] Example 5:

[0354] Based on any of the above examples, this example describes the transition from state 1 to state 3. State 1 can transition to state 3 when any of the following conditions are met:

[0355] Condition 1: If the device is configured to actively send uplink information, the state transition occurs when the device actively sends uplink signals. Active transmission can include periodic active transmission or aperiodic active transmission.

[0356] Condition 2: If the device is instructed by the network to start sending uplink signals at time t0, it will stop receiving charging signals at time T1 before t0 and transition to the uplink signal transmission state. The duration of T1 must be greater than or equal to the duration of the state transition. The duration of T1 can be defined by the protocol.

[0357] Example 6:

[0358] Based on any of the above examples, this example describes the transition from state 3 to state 1. State 3 can transition to state 1 when any of the following conditions are met:

[0359] Condition 1: If the device is sending uplink information aperiodically, and after sending an uplink message, it is impossible to predict when the next uplink message will be sent, the device will transition to state 1.

[0360] I. More specifically, if no uplink transmission occurs within T2 after the end of the uplink transmission, the device enters state 1.

[0361] Condition 2: If the device has no need to receive further downlink information after sending uplink information, it enters state 1. For example, if the device has sent uplink information and does not need to receive ACK / NACK confirmation information sent by the network side, it enters state 1.

[0362] Condition 3: If the device periodically sends uplink information. When the period is greater than T3, the device enters State 1 after an uplink transmission. (T3 should be much longer than the transition time between State 3 and State 1 to allow sufficient time for recharging.) If the period is less than or equal to T3, the device does not enter State 1.

[0363] Condition 4: The device's stored power level is below the threshold (failure to recharge the device may result in insufficient energy for subsequent information transmission and reception).

[0364] The embodiments of the present disclosure further provide an apparatus for implementing any of the above methods. For example, an apparatus is provided, comprising units or modules for implementing each step performed by a terminal in any of the above methods.

In addition, it can also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a neural network processing unit (NPU), a tensor processing unit (TPU), a deep learning processing unit (DPU), etc.
