[0158] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with those of this disclosure. Rather, they are merely examples of devices and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0159] The terminology used in this disclosure is for the purpose of describing particular embodiments only and is not intended to be limiting of the present disclosure. The singular forms “a” and “the” as used in this disclosure and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0160] It should be understood that although the terms first, second, third, etc., may be used to describe various information in embodiments of this disclosure, such information should not be limited to these terms. These terms are only used to distinguish information of the same type from one another. For example, without departing from the scope of embodiments of this disclosure, first instruction information may also be referred to as second instruction information, and similarly, second instruction information may also be referred to as first instruction information. Depending on the context, the words “if” and “suppose” as used herein may be interpreted as “when”, “when”, or “in response to a determination”.

[0161] Embodiments of this disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this disclosure, and should not be construed as limiting this 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 this embodiment 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 for 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 network (CRAN) systems, future 5th-generation (5G) systems, new radio (NR) communication systems, or future evolved public land mobile network (PLMN) systems, and Internet of Things (IoT) systems.

[0165] Terminal 101 can be a terminal, access terminal, terminal unit, terminal station, mobile station (MS), remote station, remote terminal, mobile terminal, wireless communication device, terminal agent, IoT terminal, etc. Terminal 101 may have wireless transceiver capabilities, enabling it to communicate (e.g., wireless communication) with one or more network devices in one or more communication systems and receive network services provided by these network devices, including but not limited to network device 102 shown in the diagram. Terminal 101 can also be an IoT terminal. IoT terminals have lower complexity, manufacturing costs, and maintenance costs compared to ordinary terminals. IoT terminals may not require a battery and can be powered by receiving electromagnetic signals. IoT terminals may also have a battery with a small amount of energy storage capacity, which does not require manual charging but obtains energy from external sources, such as electromagnetic waves, heat, or kinetic energy.

[0166] The charging node 103 can be a third device that sends 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 can also be an energy source node (ESN).

[0168] In some embodiments, different terminals 101 have different capabilities. For example, different terminals 101 have different types and operating methods, and their power acquisition capabilities and storage capabilities may also differ.

[0169] The capabilities of a Type I terminal (which can be referred to as device A) include: it cannot 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 an excitation signal from a network device, a Type I terminal uses backscattering to send an uplink signal. If a Type I terminal does not receive an excitation signal from a network device, it cannot actively send an uplink signal.

[0173] The capabilities of the second type of terminal (which can be called device B) include: having energy storage capabilities, but not being able to actively send uplink signals.

[0174] The capabilities of the third type of terminal (which can be called device C) include: having energy storage capabilities and being able to actively send uplink signals.

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

[0176] Of the three types of terminals mentioned above, the third type has the strongest capabilities but the highest cost. The first type has the weakest capabilities but the lowest cost. Furthermore, because the first and second types of terminals can only use backscatter mode and cannot actively send uplink signals, their coverage area is relatively small. However, the power consumption of the first and second types of terminals is lower than that of the third type.

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

[0178] In some embodiments, AmbientIoT uses backscatter communications technology, which is one of the key technologies for building a green, energy-efficient, low-cost, and flexibly deployable future Internet of Things, and is an important means of realizing "intelligent interconnection of everything".

[0179] Backscatter communication utilizes the principle of backscattering radio frequency signals to design an extremely low-power modulation and transmission technology. Since a portion of the radio frequency signal is reflected when it reaches the surface of an object, the transmitting node adjusts the matching between the receiving antenna and impedance according to the information to be transmitted, enhancing the reflection of the incident radio frequency signal. It then modulates the sensed data it acquires onto the reflected signal, completing the data transmission.

[0180] In backscatter communication, the terminal receives a radio frequency signal. The terminal's internal circuitry modulates the information to be transmitted onto the incident electromagnetic wave using methods such as load impedance modulation, and then transmits the modulated electromagnetic wave carrying the information. There are various modulation methods, such as Amplitude Shift Keying (ASK), Frequency Shift Keying (FSK), and Phase Shift Keying (PSK), etc.

[0181] For terminals using backscatter communication, the workflow is as follows: The network device sends a downlink command to the terminal. Upon receiving the downlink command, the terminal sends a corresponding response message or performs a corresponding operation to the network device. Simultaneously, the terminal needs a CWN (Continuous Wave Network) to provide electromagnetic waves for reflection. The CWN can be a single node, or it can be a base station or intermediate node (e.g., a UE) communicating with the terminal. Continuous 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 wave, or it can have some offset. The value of this offset is related to the terminal's hardware characteristics. The offset may be a fixed value, or, if the terminal's hardware supports it, one of several fixed values. Alternatively, the offset may be a dynamically adjustable value.

[0182] Backscatter communication has the following advantages compared to other communication technologies: it does not require complex radio frequency 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 the cost of terminal nodes.

[0183] In some embodiments, as shown in Figure 1B, the IoT terminal can have four types of links. Specifically:

[0184] The first link is the downlink link used to transmit downlink data, and can be called link1;

[0185] The second link is the uplink used to transmit uplink data, and can be called link2;

[0186] The third link is used to receive continuous electromagnetic waves and can be called link3;

[0187] The fourth link is used to receive charging signals and can be called link4.

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

[0189] For example: the first link connects to a downlink signal node (DSN), the second link connects to an uplink receiver (UR), the third link connects to a continuous wave node (CWN), and the fourth link connects to an energy source node (ESN).

[0190] The fourth link (Link 4) may be network-controlled. For example, network device 102 can control the ESN to enable or disable charging of the terminal. The energy in the fourth link (Link 4) can come from electromagnetic waves or from non-electromagnetic charging signals. In this case, it can be assumed that the ESN can better coordinate with network scheduling and other functions to ensure terminal charging while minimizing disruption to terminal communication.

[0191] The fourth link may also be uncontrolled by the network, or in other words, the terminal can flexibly collect energy on its own based on its capabilities and the energy sources in the actual environment. For example, it can collect electromagnetic wave energy or non-electromagnetic wave energy that is not controlled by the network. In this case, the fourth link can be considered to not exist.

[0192] The following embodiments in this disclosure are applicable to terminals with energy storage capabilities, and can be applied 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 this disclosure involve four modes, which include:

[0194] The first mode does not use energy storage to monitor downlink signals;

[0195] In the first mode, the terminal does not consume energy storage. When the network device needs to send downlink signals to the terminal, it needs to use high power to send downlink signals to the terminal, or use high power to send dedicated signals to activate the terminal.

[0196] Activation here can be understood as switching the terminal from an idle state to a working state.

[0197] The second mode uses energy storage to monitor downlink signals;

[0198] In the second mode, the terminal consumes stored energy. When the network device needs to send downlink signals to the terminal, it sends downlink signals to the terminal using low power, or it sends dedicated signals using low power, which can activate the terminal.

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

[0200] In the first mode, the terminal does not consume energy storage. When the network device needs to send downlink signals to the terminal, it needs to use high power to send downlink signals 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] In the fourth mode, the terminal consumes stored energy, and the network device can transmit downlink signals with low power. Alternatively, if the terminal uses stored energy to demodulate downlink signals, the network device can use more complex signal modulation methods (such as OFDM), higher-order modulation, or higher-rate encoding.

[0203] In some embodiments, when the terminal is listening to downlink signals, it listens to downlink signals according to a first mode or a second mode.

[0204] In some embodiments, when demodulating downlink signals, the terminal listens to downlink signals according to a third mode or a fourth mode.

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

[0206] Optionally, listening can be replaced with blind detection.

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

[0208] Optionally, demodulation can be replaced with receiving and demodulating.

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

[0210] This disclosure provides a method for processing downlink signals. Figure 2A is a flowchart of a method for processing downlink signals according to an embodiment of this disclosure. As shown in Figure 2A, the method includes the following steps:

[0211] Step S2100: The terminal determines the working mode.

[0212] In some embodiments, the terminal determines the default operating mode.

[0213] In one example, the terminal determines the default operating mode according to the protocol.

[0214] In some embodiments, the default operating modes include a default monitoring mode and a default demodulation mode; wherein:

[0215] The default listening mode is one of the first mode or the second mode.

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

[0217] In one example, the default operating modes include mode 1 and mode 3.

[0218] In one example, the default operating modes include mode 1 and mode 4.

[0219] In one example, the default operating modes include mode 2 and mode 3.

[0220] In one example, the default operating modes include mode 2 and mode 4.

[0221] In some embodiments, the terminal determines the parameters supported in the third mode according to the protocol agreement.

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

[0223] Waveform;

[0224] Modulation method;

[0225] Encoding bitrate;

[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 the operating modes supported by the terminal, which are at least one of a first mode, a second mode, a third mode, and a fourth mode.

[0231] In some embodiments, the terminal sends second capability information to the network device, wherein the second capability information is used to indicate the parameters supported by the terminal in the third mode;

[0232] In some embodiments, the terminal sends third capability information to the network device, the third capability information being used to indicate the terminal's default operating mode.

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

[0234] In some embodiments, when the operating mode is the default operating mode, the terminal processes downlink signals according to the default operating mode.

[0235] In one example, the default operating mode is the first mode, and the terminal listens for downlink signals according to the first mode.

[0236] In one example, the default operating mode is the second mode, and the terminal listens for downlink signals 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 mode 4, and the terminal demodulates the downlink signal according to mode 4.

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

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

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

[0242] Example 1:

[0243] The supported operating modes reported by the terminal to the network device are mode 1, mode 2, and mode 3.

[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 listening to downlink signals, the terminal listens to downlink signals according to the first mode.

[0246] During the demodulation of downlink signals, the terminal demodulates downlink signals according to the third mode.

[0247] In the embodiments corresponding to Figures 2B and 2C below, the automatic switching of the terminal's working mode is involved.

[0248] This disclosure provides a method for processing downlink signals. Figure 2B is a flowchart of a method for processing downlink signals according to an embodiment of this disclosure. As shown in Figure 2B, 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, and refer to step S2100.

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

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

[0253] In some embodiments, the switching method is to switch between a first mode and a second mode while monitoring downlink signals.

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

[0255] In some embodiments, during the process of monitoring and demodulating downlink signals, switching is made 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 method based on the default operating mode.

[0257] The default operating modes include the default monitoring mode and the default demodulation mode. The switching method is to switch between the default monitoring mode and the default demodulation mode.

[0258] In one example, the default listening mode is mode one, the default demodulation mode is mode two, and the switching method is to switch between mode one and mode two.

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

[0260] During the demodulation of downlink signals, the system switches between the default demodulation mode and the non-default demodulation mode. The default demodulation mode is one of the third and fourth modes, while the non-default demodulation mode is any mode other than the default demodulation mode in the third and fourth modes.

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

[0262] In one example, the switching method for the first configuration information configuration is one of the following:

[0263] During the process of monitoring and demodulating downlink signals, switching is performed between the first mode and the third mode;

[0264] During the process of monitoring and demodulating downlink signals, switching is performed between the first mode and the fourth mode.

[0265] During the process of monitoring and demodulating downlink signals, switching between the second and third modes is performed.

[0266] During the process of monitoring and demodulating downlink signals, the system switches between the second and fourth modes.

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

[0268] In some embodiments, the terminal sends first capability information to the network device.

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

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

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

[0272] In some embodiments, the terminal sends third capability information to the network device, the third capability information being used to indicate the terminal's default operating mode.

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

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

[0275] Step S2204: The terminal listens for downlink signals.

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

[0277] In one example, the switching method is as follows: when switching between the first mode and the third mode, after switching from the process of demodulating the downlink signal to the process of listening to 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. During the process of listening to the downlink signal, the downlink signal is listened to according to the first mode.

[0278] The method for processing downlink signals according to the embodiments of this disclosure may include at least one of steps S2200 to S2204. For example, step S2203 may be implemented as a standalone embodiment, and steps S2203 and S2204 may be implemented as standalone embodiments, but are not limited thereto.

[0279] In some embodiments, at least one of steps S2200 to S2202 is optional, and one or more of these steps may be omitted or substituted in different embodiments.

[0280] In some embodiments, the execution order of different steps in steps S2200 to S2204 can be changed.

[0281] Example 2:

[0282] The supported operating modes reported by the terminal to the network device are mode 1, mode 2, and mode 3.

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

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

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

[0286] During the downlink signal demodulation phase, the terminal demodulates the downlink signal according to the third mode. After the downlink signal reception ends, it enters the downlink signal monitoring phase and automatically switches according to the default switching method, that is, from the third mode to the first mode. During the downlink signal demodulation phase, the downlink signal is demodulated according to the first mode.

It automatically switches the working mode according to the default switching method. During the demodulation of the downlink signal, it detects the downlink signal according to the switched mode.

[0298] In one example, the default switching method is that when switching between the second mode and the third mode, after the terminal listens to the downlink signal for the terminal, it switches from the process of listening to the downlink signal to the process of demodulating the downlink signal. The working mode is automatically switched according to the default switching method, that is, from the second mode to the third mode. During the demodulation of the downlink signal, the downlink signal is listened to according to the third mode.

[0304] The supported switching methods reported by the terminal to the network device are the switching methods between the first mode and the third mode, and the switching methods between the first mode and the fourth mode.

[0305] The terminal determines the default working mode as the first mode and the third mode according to the protocol.

[0306] The terminal determines that the default switching method is the switching method between the first mode and the third mode.

[0307] During the process of listening to downlink signals, the terminal listens to downlink signals according to the first mode. After listening to the downlink signal for the terminal, it enters the stage of demodulating the downlink signal. It automatically switches according to the default switching method, that is, it switches from the first mode to the third mode. During the demodulation of downlink signals, the downlink signal is demodulated according to the third mode.

[0326] Step S2405: The terminal demodulates the downlink signal.

[0388] The optional implementation of step S2602 is the same as the optional implementation of step S2202, refer to step S2202.

[0389] Step S2603: The terminal listens for downlink signals.

[0390] In some embodiments, the terminal listens for downlink signals according to the default listening mode.

[0391] In step S2604, the network device sends trigger information to the terminal, which is used to indicate the switching mode.

[0392] In some embodiments, the network device sends downlink preamble information, which includes triggering information;

[0393] In some embodiments, the network device sends downlink control information, which includes triggering information;

[0394] In some embodiments, the network device sends dedicated downlink information, which includes triggering information;

[0395] In some embodiments, the network device sends a wake-up signal, which includes trigger information.

[0396] Step S2605: The terminal demodulates the downlink signal.

[0397] In some embodiments, the terminal performs a switch according to the switching method indicated by the trigger information.

[0398] In some embodiments, after the terminal detects a downlink signal for the terminal, it switches from the process of detecting the downlink signal to the process of demodulating the downlink signal. The working mode is switched according to the switching method indicated by the trigger information. During the demodulation of the downlink signal, the downlink signal is detected according to the switched mode.

[0399] In this embodiment of the disclosure, the switching mode indicated by the trigger information has a higher priority than the terminal's default switching mode.

[0400] The method for processing downlink signals according to the embodiments of this disclosure may include at least one of steps S2600 to S2605. For example, step S2604 may be implemented as a standalone embodiment, and steps S2604 and S2605 may be implemented as standalone embodiments, but are not limited thereto.

[0401] In some embodiments, at least one of steps S2600 to S2603 is optional, and one or more of these steps may be omitted or substituted in different embodiments.

[0402] In some embodiments, the execution order of different steps in steps S2600 to S2603 can be changed.

[0403] Example 9:

[0404] The supported operating modes reported by the terminal to the network device are mode 1, mode 2, mode 3, and mode 4.

[0405] The supported handover methods reported by the terminal to the network device are:

[0406] The switching method between the first and third modes, and,

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

[0408] The switching method between the first and fourth modes, and,

[0409] The switching method between the second and fourth modes.

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

[0411] During the process of the terminal listening to downlink signals, it uses the first mode to listen to downlink signals, that is, it does not use energy storage to listen to downlink signals. Before sending downlink signals, the network device sends a trigger message to the terminal using high power to activate the terminal. The trigger message also indicates the switching mode between the first mode and the third mode. The trigger message instructs the terminal to use the third mode to demodulate downlink signals during the demodulation process. (The terminal's detection of the trigger message continues the practice of not using energy storage in the first mode, that is, the default is to detect the trigger message according to the third mode).

[0412] Optionally, the trigger information can also indicate parameters when the terminal is operating in the third mode.

[0413] Based on the triggering information and the default operating mode, the terminal can determine whether the switching method triggered by the network device is a switching method 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 demodulation process.

[0415] After the terminal demodulates the downlink signal, it starts listening to the downlink signal and automatically switches modes, that is, from the third mode to the first mode. During the process of listening to the downlink signal, it listens to the downlink signal according to the first mode.

[0416] Example 10:

[0417] The supported operating modes reported by the terminal to the network device are mode 1, mode 2, mode 3, and mode 4.

[0418] The supported handover methods reported by the terminal to the network device are:

[0419] The switching method between the first and third modes, and,

[0420] The switching method between the second and third modes, and,

[0421] The switching method between the first and fourth modes, and,

[0422] The switching method between the second and fourth modes.

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

[0424] During the process of the terminal listening to downlink signals, it uses the second mode to listen to downlink signals, which is to use energy storage to listen to downlink signals. Before sending downlink signals, the network device sends a trigger message to the terminal using low power to activate the terminal. The trigger message also indicates the switching mode between the second mode and the fourth mode. The method by which the trigger message indicates this switching mode is that it instructs the terminal to use the fourth mode to demodulate downlink signals during the demodulation process. (Note that the terminal's detection of the trigger message continues the second mode's practice of not using energy storage, meaning that the default is to detect the trigger message according to the fourth mode).

[0425] Optionally, the trigger information can also indicate the parameters when the terminal is operating in the fourth mode.

[0426] Based on the triggering information and the default operating mode, the terminal can determine whether the switching method triggered by the network device is a switching method 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 demodulation process.

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

[0429] Example 11:

[0430] The supported operating modes reported by the terminal to the network device are mode 1, mode 2, mode 3, and mode 4.

[0431] The supported handover methods reported by the terminal to the network device are:

[0432] The switching method between the first and third modes, and,

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

[0434] The switching method between the first and fourth modes, and,

[0435] The switching method between the second and fourth modes.

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

[0437] During the process of the terminal listening to downlink signals, it uses the second mode to listen to downlink signals, which is to use energy storage to listen to downlink signals. Before sending downlink signals, the network device sends a trigger message to the terminal using low power to activate the terminal. The trigger message also indicates the switching method between the second mode and the third mode. The method of indicating this switching method in the trigger message is that it instructs the terminal to use the third mode to demodulate downlink signals during the demodulation process. (Note that the terminal's detection of the trigger message continues the practice of not using energy storage in the second mode, that is, the default is to detect the trigger message according to the third mode).

[0438] Optionally, the trigger information can also indicate parameters when the terminal is operating in the third mode.

[0439] Based on the triggering information and the default operating mode, the terminal can determine whether the switching method triggered by the network device is a switching method 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 demodulation process.

[0441] After the terminal demodulates the downlink signal, it starts listening to the downlink signal and automatically switches modes, that is, from the third mode to the second mode. During the downlink signal listening process, the downlink signal is listened to according to the second mode.

[0456] In some embodiments, at least one of steps S2700 to S2703 is optional, and one or more of these steps may be omitted or substituted in different embodiments.

[0457] In some embodiments, the execution order of different steps in steps S2700 to S2705 can be changed.

[0461] The switching method between the first and third modes, and,

[0462] The switching method between the second and third modes, and,

[0463] The method for switching between the first mode and the second mode.

[0464] The terminal determines the default working mode as the first mode and the third mode according to the protocol.

[0465] During the process of the terminal listening to downlink signals, it uses the first mode to listen to downlink signals, that is, it does not use power storage to listen to downlink signals. Before sending downlink signals, the network device sends a trigger message to the terminal using high power to activate the terminal. The trigger message also indicates the switching mode between the first mode and the second mode. The method by which the trigger message indicates this switching mode is that it instructs the terminal to use the second mode to demodulate the downlink signals during the downlink signal listening process.

[0466] Based on the triggering information and the default listening mode, the terminal can determine whether the switching method triggered by the network device is a switching method between the first mode and the second mode.

[0467] During the subsequent process of monitoring downlink signals, the terminal switches modes, that is, from the first mode to the second mode. During the process of monitoring downlink signals, the terminal monitors downlink signals according to the second mode.

[0468] In another implementation, the triggering information is a wake-up signal. After receiving the wake-up signal, the terminal switches from the first mode to the second mode to obtain better downlink signal monitoring capabilities.

[0472] The switching method between the first and third modes, and,

[0473] The switching method between the second and third modes, and,

[0474] The method for switching between the first mode and the second mode.

[0475] The terminal determines the default working mode as the second mode and the third mode according to the protocol.

[0476] During the process of the terminal listening to downlink signals, it uses a second mode to listen to downlink signals, that is, to use energy storage to listen to downlink signals. Before sending downlink signals, the network device sends a trigger message to the terminal using low power to activate the terminal. The trigger message also indicates the switching mode between the first mode and the second mode. The method by which the trigger message indicates this switching mode is by instructing the terminal to use the first mode to demodulate the downlink signals during the downlink signal listening process.

[0477] Based on the triggering information and the default operating mode, the terminal can determine whether the switching method triggered by the network device is a switching method between the first mode and the second mode.

[0478] During the subsequent process of monitoring downlink signals, the terminal switches modes, that is, from the second mode to the first mode. During the process of monitoring downlink signals, it monitors downlink signals according to the first mode.

[0479] This disclosure provides a method for processing downlink signals. Figure 2H is a flowchart of a method for processing downlink signals according to an embodiment of this disclosure. As shown in Figure 2H, the method includes the following steps:

[0480] Step S2800: The terminal determines the working mode.

[0481] The optional implementation of step S2800 is the same as the optional implementation of step S2100, and refer to step S2100.

[0490] In some embodiments, the terminal switches its operating mode according to the switching method indicated by the trigger information, and demodulates the downlink signal according to the switched mode during the demodulation of the downlink signal.

[0491] The method for processing downlink signals according to the embodiments of this disclosure may include at least one of steps S2800 to S2805. For example, step S2804 may be implemented as a standalone embodiment, and steps S2804 and S2805 may be implemented as standalone embodiments, but are not limited thereto.

[0492] In some embodiments, at least one of steps S2800 to S2803 is optional, and one or more of these steps may be omitted or substituted in different embodiments.

[0500] The terminal determines the default working mode as the second mode and the third mode according to the protocol.

[0501] During the demodulation of downlink signals by the terminal, the third mode is used to listen to the downlink signals, meaning that power storage is not used for demodulation. Before transmitting the downlink signals, the network device sends a trigger message to the terminal using high power. The trigger message also indicates the switching mode between the third and fourth modes. The method by which the trigger message indicates this switching mode is to instruct the terminal to use the fourth mode to demodulate the downlink signals during the listening process.

[0502] Based on the triggering information and the default operating mode, the terminal can determine whether the switching method triggered by the network device is a switching method between the third mode and the fourth mode.

[0503] During the subsequent demodulation of downlink signals, the terminal automatically switches modes, that is, from the third mode to the fourth mode. During the demodulation of downlink signals, the terminal listens for downlink signals according to the fourth mode.

[0511] During the demodulation of downlink signals by the terminal, a fourth mode is used to listen to the downlink signals, meaning that power storage is not used for demodulation. Before transmitting the downlink signals, the network device sends a trigger message to the terminal using low power. The trigger message also indicates the switching mode between the third and fourth modes. The trigger message indicates this switching mode by instructing the terminal to use the third mode to demodulate the downlink signals during the listening process.
