[0160] It should be understood that although the terms first, second, third, etc. may be used to describe various information in the embodiments of the present disclosure, such information should not be limited to these terms. 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".

[0161] 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.

[0162] In some embodiments, the first device is a terminal, the second device is a network device, and the fourth device is a charging node.

[0163] 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 and a network device 102. 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.

[0164] 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.

[0165] 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.

[0166] 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.

[0167] The charging node 103 may also be an energy source node (ESN).

[0168] 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.

[0169] The capabilities of the first type of terminal (which may be referred to as device A) include: being unable to actively send uplink signals.

[0170] 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.

[0171] In some possible embodiments, the first type of terminal (which may be referred to as device A) can only passively send uplink signals.

[0172] 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.

[0173] 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.

[0174] 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.

[0175] In one example, the third type of terminal has a radio frequency (RF) module that actively sends uplink signals.

[0176] 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.

[0177] In some embodiments, the terminal 101 is an Ambient-IoT.

[0178] 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".

[0179] 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.

[0180] 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).

[0181] 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.

[0182] 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.

[0183] In some embodiments, as shown in FIG1B , the IoT terminal may have four types of links. Specifically:

[0184] The first link is the downlink for transmitting downlink data, which can be called link1;

[0185] The second link is the uplink for transmitting uplink data and can be called link2;

[0186] The third link is used to receive continuous electromagnetic waves and can be called link 3;

[0187] The fourth link is a link for receiving charging signals, which may be referred to as link 4.

[0188] The four nodes involved in these four links can be the same node, or two, three, or four separate nodes.

[0189] 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).

[0190] 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.

[0191] 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.

[0192] The following embodiments of the present disclosure are applicable to terminals having energy storage capabilities, and may be applicable to a first type of terminal (which may be referred to as device A), a second type of terminal (which may be referred to as device B), or a third type of terminal (which may be referred to as device C).

[0193] The embodiments of the present disclosure involve four modes, which include:

[0194] In the first mode, the downlink signal is monitored without using energy storage;

[0195] Among them, the terminal does not consume stored energy in the first mode. When the network device needs to send a downlink signal to the terminal, it needs to use high power to send the downlink signal to the terminal, or use high power to send a dedicated signal to activate the terminal.

[0196] The activation here can be understood as converting the terminal from an idle state to a working state.

[0197] In the second mode, energy storage is used to monitor downlink signals;

[0198] Among them, the terminal consumes stored energy in the second mode. When the network device needs to send a downlink signal to the terminal, it uses low power to send the downlink signal to the terminal, or uses low power to send a dedicated signal to activate the terminal.

[0199] The third mode does not use energy storage to demodulate the downlink signal;

[0200] Among them, the terminal does not consume stored energy in the first mode. When the network device needs to send a downlink signal to the terminal, it needs to use high power to send the downlink signal to the terminal to ensure that the terminal can use the energy provided by the high-power signal to demodulate the downlink signal.

[0201] The fourth mode uses energy storage to demodulate the downlink signal.

[0202] Among them, the terminal consumes stored energy in the fourth mode, and the network device can use low power to send downlink signals, or when the terminal uses stored energy to demodulate the downlink signal, the network device can use a more complex signal modulation method (such as OFDM) or use high-order modulation or high-code rate encoding.

[0203] In some embodiments, when monitoring a downlink signal, the terminal monitors the downlink signal according to the first mode or the second mode.

[0204] In some embodiments, when demodulating the downlink signal, the terminal monitors the downlink signal according to the third mode or the fourth mode.

[0205] In some embodiments, monitoring means that the terminal receives information and attempts to decode to determine whether it is a downlink signal sent to the terminal without knowing the time-frequency resources of the downlink signal.

[0206] Optionally, monitoring can be replaced by blind detection.

[0207] In some embodiments, demodulation refers to the terminal receiving and demodulating the downlink signal when the time-frequency resources of the downlink signal are known.

[0208] Optionally, demodulation may be replaced by reception and demodulation.

[0209] In the embodiment corresponding to FIG. 2A below, the working mode switching of the terminal is not involved.

[0214] In some embodiments, the default operating mode includes a default listening mode and a default demodulation mode; wherein:

[0215] The default monitoring mode is one of the first mode and the second mode.

[0216] The default demodulation mode is one of the third mode and the fourth mode.

[0218] In one example, the default operating mode includes a first mode and a fourth mode.

[0219] In one example, the default operating mode includes a second mode and a third mode.

[0222] The parameters include at least one of the following:

[0223] waveform;

[0224] Modulation method;

[0225] Encoding bit rate;

[0226] Chip rate.

[0227] In some embodiments, the terminal receives configuration information sent by the network device for configuring parameters supported in the third mode.

[0228] Step S2101: The terminal sends capability information to the network device.

[0229] In some embodiments, the terminal sends first capability information to the network device.

[0230] In one example, the first capability information is used to indicate an operating mode supported by the terminal, and the operating mode is at least one of the first mode, the second mode, the third mode, and the fourth mode.

[0233] Step S2102: The terminal processes the downlink signal.

[0236] In one example, the default working mode is the second mode, and the terminal monitors the downlink signal according to the second mode.

[0237] In one example, the default operating mode is the third mode, and the terminal demodulates the downlink signal according to the third mode.

[0238] In one example, the default operating mode is the fourth mode, and the terminal demodulates the downlink signal according to the fourth mode.

[0239] The method for processing downlink signals involved in the embodiments of the present disclosure may include at least one of steps S2100 to S2102. For example, step S2102 may be implemented as an independent embodiment, and steps S2101 and S2102 may be implemented as independent embodiments, but are not limited thereto.

[0240] In some embodiments, step S2100 and step S2102 are optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0241] In some embodiments, the execution order of different steps in steps S2100 to S2102 can be changed.

[0242] Example embodiment 1:

[0243] The supported working modes reported by the terminal to the network device are the first mode, the second mode and the third mode.

[0244] The default operating modes determined by the terminal according to the protocol include the first mode and the third mode.

[0245] During the process of monitoring the downlink signal, the terminal monitors the downlink signal according to the first mode.

[0246] During the process of demodulating the downlink signal, the terminal demodulates the downlink signal according to the third mode.

[0247] The following embodiments corresponding to FIG. 2B and FIG. 2C involve automatic switching of the operating mode of the terminal.

[0248] The present disclosure provides a method for processing downlink signals. FIG2B is a flow chart of a method for processing downlink signals according to an embodiment of the present disclosure. As shown in FIG2B , the method includes the following steps:

[0249] Step S2200: The terminal determines the working mode.

[0250] The optional implementation of step S2200 is the same as the optional implementation of step S2100, refer to step S2100.

[0251] Step S2201: The terminal determines the switching mode.

[0252] In some embodiments, the switching mode refers to a mode of switching between two operating modes.

[0253] In some embodiments, the switching manner is: switching between the first mode and the second mode during the process of monitoring the downlink signal.

[0254] In some embodiments, during the process of demodulating the downlink signal, switching is performed between the third mode and the fourth mode.

[0255] In some embodiments, during monitoring and demodulating downlink signals, switching is performed between a fifth mode and a sixth mode, wherein the fifth mode is one of the first mode and the second mode, and the sixth mode is one of the third mode and the fourth mode.

[0256] In some embodiments, the terminal determines the switching mode according to a default working mode.

[0257] The default working mode includes a default monitoring mode and a default demodulation mode, and the switching mode is determined as: switching between the default monitoring mode and the default demodulation mode.

[0258] In an example, the default monitoring mode is the first mode, the default demodulation mode is the second mode, and the switching manner is: switching between the first mode and the second mode.

[0259] In some embodiments, during monitoring of downlink signals, switching is performed between a default monitoring mode and a non-default monitoring mode, where the default monitoring mode is one of a first mode and a second mode, and the non-default monitoring mode is a mode other than the default monitoring mode between the first mode and the second mode.

[0260] During the process of demodulating the downlink signal, switching is performed between the default demodulation mode and the non-default demodulation mode. The default demodulation mode is one of the third mode and the fourth mode, and the non-default demodulation mode is a mode other than the default demodulation mode between the third mode and the fourth mode.

[0261] In some embodiments, the switching mode is a switching mode dynamically configured by the network device. Step S2201 is: the network device sends first configuration information to the terminal, the first configuration information is used to configure the switching mode of the terminal, and the terminal determines the switching mode according to the first configuration information, that is, determines that the switching mode is the switching mode configured by the first configuration information.

[0262] In one example, the switching mode configured by the first configuration information is one of the following:

[0263] In the process of monitoring the downlink signal and demodulating the downlink signal, switching between the first mode and the third mode;

[0264] Switching between the first mode and the fourth mode during monitoring and demodulating the downlink signal;

[0265] In the process of monitoring the downlink signal and demodulating the downlink signal, switching between the second mode and the third mode;

[0266] In the process of monitoring the downlink signal and demodulating the downlink signal, switching is performed between the second mode and the fourth mode.

[0267] Step S2202: The terminal sends capability information to the network device.

[0269] In one example, the first capability information is used to indicate an operating mode supported by the terminal, and the operating mode is at least one of the first mode, the second mode, the third mode, and the fourth mode.

[0270] In some embodiments, the first capability information is further used to indicate a switching mode supported by the terminal.

[0271] In some embodiments, the terminal sends second capability information to the network device, where the second capability information is used to indicate parameters supported by the terminal in the third mode;

[0272] In some embodiments, the terminal sends third capability information to the network device, where the third capability information is used to indicate a default working mode of the terminal.

[0273] Step S2203: The terminal demodulates the downlink signal.

[0274] In some embodiments, the terminal demodulates the downlink signal according to a default demodulation mode.

[0275] Step S2204: The terminal monitors the downlink signal.

[0276] In some embodiments, after the terminal completes receiving the downlink signal, it switches from the process of demodulating the downlink signal to the process of monitoring the downlink signal, and automatically switches the working mode according to the default switching method. During the process of monitoring the downlink signal, the downlink signal is monitored according to the switched mode.

[0277] In one example, when switching between the first mode and the third mode, after switching from the process of demodulating the downlink signal to the process of monitoring the downlink signal, the working mode is automatically switched according to the default switching method, that is, from the third mode to the first mode, and in the process of monitoring the downlink signal, the downlink signal is monitored according to the first mode.

[0283] The supportable switching modes reported by the terminal to the network device are the switching mode between the first mode and the third mode, and the switching mode between the first mode and the fourth mode.

[0284] The terminal determines the default working modes as the first mode and the third mode according to the protocol.

[0285] The terminal determines that the default switching mode is the switching mode between the first mode and the third mode.

[0286] In the stage of demodulating the downlink signal, the terminal demodulates the downlink signal according to the third mode.

[0403] Example embodiment 9:

[0404] The supported working modes reported by the terminal to the network device are the first mode, the second mode, the third mode and the fourth mode.

[0405] The supported switching modes reported by the terminal to the network device are:

[0406] a switching method between the first mode and the third mode, and

[0407] The switching method between the second mode and the third mode, and

[0408] a switching method between the first mode and the fourth mode, and

[0409] Switching method between the second mode and the fourth mode.

[0410] The terminal determines the default working modes as the first mode and the fourth mode according to the protocol.

[0411] In the process of the terminal monitoring the downlink signal, the first mode is used to monitor the downlink signal, that is, energy storage is not used to monitor the downlink signal. Before sending the downlink signal, the network device uses high power to send a trigger message to the terminal to activate the terminal. The trigger information also indicates that the switching mode is a switching mode between the first mode and the third mode. The trigger information indicates that the terminal uses the third mode to demodulate the downlink signal in the process of demodulating the downlink signal. (Wherein, the terminal detects the trigger information and continues the first mode without using energy storage, that is, the default is to detect the trigger information according to the third mode).

[0412] Optionally, the trigger information may further indicate parameters of the terminal when operating in the third mode.

[0413] According to the trigger information and the default working mode, the terminal can determine that the switching mode triggered by the network device is a switching mode between the first mode and the third mode.

[0414] After receiving the trigger information, the terminal demodulates the downlink signal according to the third mode during the process of demodulating the downlink signal.

[0415] After the terminal completes demodulating the downlink signal, it starts monitoring the downlink signal and automatically switches the mode, that is, switches from the third mode to the first mode. During the process of monitoring the downlink signal, the terminal monitors the downlink signal according to the first mode.

[0416] Example embodiment 10:

[0417] The supported working modes reported by the terminal to the network device are the first mode, the second mode, the third mode and the fourth mode.

[0418] The supported switching modes reported by the terminal to the network device are:

[0422] Switching method between the second mode and the fourth mode.

[0423] The terminal determines the default working modes as the second mode and the third mode according to the protocol.

[0424] In the process of the terminal monitoring the downlink signal, the second mode is used to monitor the downlink signal, that is, energy storage is used to monitor the downlink signal. Before sending the downlink signal, the network device uses low power to send a trigger message to the terminal to activate the terminal. The trigger information also indicates that the switching mode is a switching mode between the second mode and the fourth mode. The method in which the trigger information indicates the switching mode is to instruct the terminal in the trigger information to use the fourth mode to demodulate the downlink signal in the process of demodulating the downlink signal. (Wherein, the terminal detects the trigger information and continues the second mode without using energy storage, that is, the default is to detect the trigger information according to the fourth mode).

[0425] Optionally, the trigger information may further indicate parameters of the terminal when operating in the fourth mode.

[0426] According to the trigger information and the default working mode, the terminal can determine that the switching mode triggered by the network device is a switching mode between the second mode and the fourth mode.

[0427] After receiving the trigger information, the terminal demodulates the downlink signal according to the fourth mode during the process of demodulating the downlink signal.

[0428] After the terminal completes demodulating the downlink signal, it starts monitoring the downlink signal and automatically switches the mode, that is, switches from the fourth mode to the second mode. During the process of monitoring the downlink signal, the terminal monitors the downlink signal according to the second mode.

[0429] Example embodiment 11:

[0430] The supported working modes reported by the terminal to the network device are the first mode, the second mode, the third mode and the fourth mode.

[0433] The switching method between the second mode and the third mode, and

[0434] a switching method between the first mode and the fourth mode, and

[0435] Switching method between the second mode and the fourth mode.

[0436] The terminal determines the default working modes as the second mode and the fourth mode according to the protocol.

[0437] In the process of the terminal monitoring the downlink signal, the second mode is used to monitor the downlink signal, that is, energy storage is used to monitor the downlink signal. Before sending the downlink signal, the network device uses low power to send a trigger message to the terminal to activate the terminal. The trigger information also indicates that the switching mode is a switching mode between the second mode and the third mode. The method in which the trigger information indicates the switching mode is to instruct the terminal in the trigger information to use the third mode to demodulate the downlink signal in the process of demodulating the downlink signal. (Wherein, the terminal detects the trigger information and continues the second mode without using energy storage, that is, the default is to detect the trigger information according to the third mode).

[0438] Optionally, the trigger information may further indicate parameters of the terminal when operating in the third mode.

[0439] According to the trigger information and the default working mode, the terminal can determine that the switching mode triggered by the network device is a switching mode between the second mode and the third mode.

[0440] After receiving the trigger information, the terminal demodulates the downlink signal according to the third mode during the process of demodulating the downlink signal.

[0441] After the terminal completes demodulating the downlink signal, it starts monitoring the downlink signal and automatically switches the mode, that is, switches from the third mode to the second mode. During the process of monitoring the downlink signal, the terminal monitors the downlink signal according to the second mode.
