[0037] The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0038] In order to facilitate understanding of the technical solutions of the embodiments of the present application, the related technologies of the embodiments of the present application are described below. The following related technologies can be combined with the technical solutions of the embodiments of the present application in any way, and all of them fall within the protection scope of the embodiments of the present application.

[0039] In standardization discussions, zero-power IoT can also be called Ambient Power Enabled IoT, or simply Ambient IoT. Ambient IoT refers to IoT devices that utilize various forms of environmental energy, such as radio frequency energy, light energy, solar energy, thermal energy, and mechanical energy. These devices may have no energy storage capacity or very limited energy storage capacity (e.g., using capacitors with a capacitance of tens of microseconds).

[0040] ●The development needs of cellular passive IoT

[0041] Cellular IoT is booming, with 3GPP standardizing IoT technologies such as NB-IoT, MTC, and RedCap. However, there are still many IoT communication needs in various scenarios that cannot be met using existing technologies, such as:

[0042] - Harsh communication environment

[0043] Some IoT scenarios may face extreme environments such as high temperatures, extremely low temperatures, high humidity, high pressure, high radiation, or high-speed movement. Examples include ultra-high-voltage substations, high-speed train track monitoring, environmental monitoring in frigid regions, and industrial production lines. In these scenarios, existing IoT terminals will be unable to function due to the limitations of conventional power supplies. Furthermore, extreme working environments are also detrimental to IoT maintenance, such as battery replacement.

[0044] - Minimal size terminal form factor requirements

[0045] In certain IoT communication scenarios, such as food traceability, commodity distribution, and smart wearables, terminals require extremely small sizes for convenient use in these environments. For example, IoT terminals used for commodity management in the distribution process typically use electronic tags, embedded in very small packages. Furthermore, lightweight wearable devices can enhance the user experience while meeting user needs.

[0046] - Extremely low-cost IoT communication needs

[0047] Numerous IoT communication scenarios require IoT terminals to be sufficiently inexpensive to enhance their competitiveness compared to other alternative technologies. For example, in logistics or warehousing scenarios, to facilitate the management of large quantities of goods in circulation, IoT terminals can be attached to each item, enabling precise management of the entire logistics process and lifecycle through communication between the terminal and the logistics network. These scenarios necessitate that IoT terminals be priced competitively.

[0048] Therefore, in order to cover these unmet IoT communication needs, it is also necessary to develop ultra-low cost, extremely small size, battery-free / maintenance-free IoT in cellular networks, and zero-power IoT can meet this need.

[0049] ●Application scenarios of zero-power communication

[0050] Zero-power communication (ZHW) has significant advantages such as extremely low cost, zero power consumption, and small size, and can be widely used in various industries, such as logistics, smart warehousing, smart agriculture, energy and power, and industrial internet for vertical industries; it can also be used in personal applications such as smart wearables and smart homes.

[0051] Based on the discussion of Ambient IoT application scenarios in 3GPP SA1, Ambient IoT can be used in at least the following four scenarios:

[0052] Object recognition, such as in logistics, production line product management, and supply chain management;

[0053] Environmental monitoring, such as monitoring of temperature, humidity, and harmful gases in the work environment and natural environment;

[0054] Location services, such as indoor positioning, smart item finding, and production line item positioning;

[0055] Intelligent control, such as the intelligent control of various electrical appliances in smart homes (turning on and off air conditioners, adjusting temperature), and the intelligent control of various facilities in agricultural greenhouses (automatic irrigation, fertilization).

[0056] ●Classification of zero-power devices based on different transmitter designs

[0057] As is well known, zero-power IoT services, like other IoT services, will primarily focus on upstream applications. Therefore, terminals can be categorized into zero-power devices as follows:

[0058] 1) Zero-power devices based on backscattering

[0059] These zero-power devices transmit uplink data using the backscattering method described above. These devices do not have an active transmitter for active transmission, but only a backscattering transmitter. Therefore, when this type of terminal transmits data, a network device needs to provide a carrier wave, and the terminal device uses this carrier wave for backscattering to achieve data transmission.

[0060] 2) Zero-power devices based on active transmitters

[0061] These zero-power devices use active transmitters with active transmission capabilities for uplink data transmission. Therefore, when sending data, these devices can transmit data using their own active transmitters without requiring a carrier wave from network equipment. Suitable active transmitters for zero-power devices include, for example, ultra-low-power ASK or ultra-low-power FSK transmitters. Based on current implementations, these transmitters can reduce overall power consumption to 400–600 µW when transmitting a 100 µW signal.

[0062] 3) Zero-power devices that simultaneously feature backscattering and active transmitters.

[0063] These terminals can support both backscatter and active transmitters. The terminal can determine which uplink signal transmission method to use based on different conditions (such as battery level and available ambient energy) or the scheduling of network devices: whether to use backscatter or active transmitter for active transmission.

[0064] Figure 1 is a schematic diagram of a communication system provided in an embodiment of this application. As shown in Figure 1, after the zero-power device 100 enters an electromagnetic field, it receives radio frequency signals emitted by the power supply device 101. The zero-power device 100 utilizes the energy obtained from the electromagnetic field generated in space to communicate with the power supply device 101 by actively transmitting or reflecting signals. The communication protocol can be Bluetooth BLE or WiFi 802.11xx, etc. The zero-power device 100 may also have a memory or sensor for storing basic information (such as item identification ID, location, etc.) or acquiring sensor data such as ambient temperature and humidity. The zero-power device 100 features environmental energy harvesting, low-power computing, and ultra-low-power communication. In addition, the power supply device 101 can be a dedicated device with a reader / writer, which has data processing and computing functions.

[0065] ●Power supply signal in zero-power communication systems

[0066] In schemes where the power supply signal is a radio frequency energy signal, the power supply signal carrier can be a base station, a smartphone, a smart gateway, a charging station, a micro base station, etc.

[0067] - In terms of frequency band, the radio waves used for power supply can be low frequency, medium frequency, high frequency, etc.;

[0068] - In terms of waveform, the radio waves used for power supply can be sine waves, square waves, triangle waves, pulses, rectangular waves, etc.; in addition, the radio waves used for power supply can be continuous waves or discontinuous waves (i.e., allowing a certain period of interruption).

[0069] - For example, the radio waves used for power supply may be a signal specified in the 3GPP standard, such as SRS, PUSCH, PRACH, PUCCH, PDCCH, PDSCH, PBCH, etc.

[0070] Power signals can provide power to trigger, control, or wake up zero-power devices, such as Wake-up Radio (WUR).

[0071] Based on the energy source and usage method of zero-power devices, zero-power devices can be classified into the following types:

[0072] 1) Passive zero-power devices

[0073] Zero-power devices do not require an internal battery. When a zero-power device is near a network device (such as a reader in an RFID system), it falls within the near-field range of the network device's antenna radiation. Therefore, the zero-power device's antenna generates an induced current through electromagnetic induction, which drives the device's low-power chip circuitry. This enables demodulation of the forward link signal and modulation of the backward link signal. For backscatter links, the zero-power device uses backscattering to transmit signals.

[0074] As can be seen, passive zero-power devices do not require built-in batteries to drive either the forward or reverse link, making them truly zero-power devices.

[0075] Passive zero-power devices do not require batteries, and their RF and baseband circuits are very simple. For example, they do not require LNA (low noise amplifier), PA (power amplifier), crystal oscillator, ADC, etc. Therefore, they have many advantages such as small size, light weight, very low price, and long service life.

[0076] Passive zero-power devices can also support other energy harvesting methods. By harvesting energy from the environment (such as light energy, heat energy, kinetic energy, mechanical energy, etc.), they can obtain energy to drive the circuit and support the terminal device to communicate.

[0077] 2) Semi-passive zero-power devices

[0078] Semi-passive zero-power devices do not have conventional batteries installed, but they can use RF energy harvesting modules to harvest radio wave energy or use energy harvesting modules to harvest energy from the environment (such as solar energy, thermal energy, mechanical vibration energy, etc.), and store the harvested energy in an energy storage unit (such as a capacitor). After obtaining energy, the energy storage unit can drive the low-power chip circuitry of the zero-power device, enabling demodulation of the forward link signal and modulation of the backward link signal. For the backscatter link, the zero-power device uses backscattering to transmit signals.

[0079] As can be seen, semi-passive zero-power devices do not require built-in batteries to drive either the forward or reverse link. Although they use energy stored in capacitors during operation, the energy comes from the radio energy collected by the energy harvesting module, thus making them a true zero-power device.

[0080] Semi-passive zero-power devices inherit many advantages of passive zero-power devices, and therefore have many advantages such as small size, light weight, very low price, and long service life.

[0081] 3) Active zero-power devices

[0082] In some scenarios, zero-power devices can also be active zero-power devices, which can have a built-in battery. The battery powers the low-power chip circuitry of the zero-power device, enabling demodulation of the forward link signal and modulation of the backward link signal. However, for the backscatter link, the zero-power device uses backscattering to transmit the signal. Therefore, the zero power consumption of this type of terminal is mainly reflected in the fact that the signal transmission of the backward link does not require the terminal's own power, but instead uses backscattering.

[0083] Active zero-power devices use a built-in battery to power the RFID chip, increasing the tag's read / write distance and improving communication reliability. Therefore, they are used in scenarios with relatively high requirements for communication distance and read latency.

[0084] Some zero-power devices, such as semi-passive zero-power devices or active zero-power devices, can have the ability to actively transmit. That is, in addition to communicating through backscattering, the backlink can also communicate through active transmission.

[0085] The above provides a brief explanation of the relevant technologies / terms involved in this application, which will not be repeated in the following embodiments.

[0086] This application provides a wireless communication method, apparatus, device, chip, and storage medium. In the method, a first device transmits a power supply signal; wherein the power supply signal is used to power a second device, and the power supply signal is related to a power supply mode; thus, power is supplied to the second device.

[0087] It should be noted that, in the embodiments of this application, "zero-power device" may refer to, for example, a "zero-power terminal". In the embodiments of this application, "power supply signal" may refer to, for example, a "radio wave used for power supply".

[0088] To facilitate understanding of the technical solutions of the embodiments of this application, the technical solutions of this application are described in detail below through specific embodiments. The above-mentioned related technologies are optional solutions and can be arbitrarily combined with the technical solutions of the embodiments of this application, all of which fall within the protection scope of the embodiments of this application. The embodiments of this application include at least some of the following contents.

[0089] Figure 2 is a flowchart illustrating the wireless communication method provided in an embodiment of this application. As shown in Figure 2, the method may include the following steps:

[0090] S201, the first device transmits a power supply signal; wherein, the power supply signal is used to supply power to the second device, and the power supply signal is related to the power supply mode.

[0091] In this embodiment, the first device can also be understood as a power supply device, which can be a network device, a terminal device, a charging station, or other energy source node. For example, a network device can be a base station, a micro base station, a smart gateway, etc., and a terminal device can be called a user equipment (UE), access terminal, user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent, or user device, etc. A terminal device can be a WLAN station (STAION, ST), a cellular phone, a smartphone, an in-vehicle device, a computing device, a wearable device, etc. This embodiment does not limit the type of power supply device; in short, it only needs to have the ability to transmit radio frequency energy signals.

[0092] In the embodiments of this application, the second device may be a zero-power device, such as the passive zero-power device, semi-passive zero-power device or active zero-power device mentioned above.

[0093] In this embodiment, the type of power supply signal is not limited. From a frequency band perspective, the power supply signal can be a low-frequency signal, a medium-frequency signal, or a high-frequency signal, etc. From a waveform perspective, the power supply signal can be a sine wave, a square wave, a triangular wave, a pulse, a rectangular wave, etc. In addition, the power supply signal can be a continuous wave or a discontinuous wave (i.e., allowing for a certain period of interruption). The power supply signal can be a signal specified in the 3GPP standard, such as SRS, PUSCH, PRACH, PUCCH, PDCCH, PDSCH, PBCH, etc. In short, the power supply signal can be various types of radio wave / RF power signals.

[0094] In this embodiment, the power supply signal is related to the power supply mode. Furthermore, the first device transmits the power supply signal according to the power supply mode.

[0095] In some embodiments, the power supply mode includes one or more of the following:

[0096] (1) Information on the transmission frequency of the power supply signal;

[0097] (2) Transmission power information of the power supply signal;

[0098] (3) Transmission time information of power supply signal.

[0099] Furthermore, in some embodiments, the transmission frequency information of the power supply signal includes one or more frequency points, wherein the power supply signal is allowed to hop frequencies between one or more frequency points in a competitive or random manner within a power supply operation / duration. In the embodiments of this application, the above-mentioned transmission time information of the power supply signals at different frequency points may be the same or different.

[0100] Furthermore, in some embodiments, the transmission time information of the power supply signal includes one or more of the following:

[0101] (1) Charging operation / duration or Total Powering period; The charging operation / duration includes one or more launch cycles;

[0102] (2) Power Repetition period (Tx); One transmission period includes on duration and off duration;

[0103] (3) On duration (or Tx power length); On duration refers to the total duration of a single continuous or multiple discontinuous transmission of power signals (such as high-level signals) within the transmission cycle;

[0104] (4) Off duration; Off duration refers to the total duration of a single or multiple times during a transmission cycle when the transmission power signal (such as a high-level signal) is turned off.

[0105] (5) Transmission on time (Tx on or power on); Transmission on time refers to the duration of a single continuous transmission of a power signal (such as a high-level signal) within the on-time period;

[0106] (6) Transmit Off Time (Tx off or power off); Transmit off time refers to the duration during which the transmit power signal (such as a high-level signal) is turned off once during the on-time period;

[0107] (7) First duty cycle; The first duty cycle refers to the duty cycle of the power supply signal (such as a high-level signal) during the on-time duration;

[0108] (8) Second duty cycle; The second duty cycle refers to the duty cycle of the power supply signal (such as a high-level signal) during the transmission cycle;

[0109] (9) Third duty cycle; The third duty cycle refers to the duty cycle of the power supply signal (such as a high-level signal) during the power supply duration.

[0110] The power supply duration in the power supply signal transmission time information may include one or more transmission cycles, and the time lengths (i.e., durations, lengths) of multiple transmission cycles may be the same or different.

[0111] For example, Figure 3 is a schematic diagram of a power supply signal provided in an embodiment of this application. As shown in Figure 3, the power supply signal includes multiple transmission cycles, and the lengths of the multiple transmission cycles T1 are the same; wherein, T0 represents an example of an on duration, as shown in Figure 3, in this example, an on duration includes a transmission on time (Tx on or power on).

[0112] For example, Figure 4 is a schematic diagram of the power supply signal provided in an embodiment of this application. As shown in Figure 4, the power supply signal includes multiple transmission cycles, and the lengths of some transmission cycles are different, such as T1 and T2 shown in Figure 4. It can be seen that in Figure 4, the power supply signal hops between one or more frequency points.

[0113] For the transmission cycle of the power supply signal, the on-time duration can be continuous or discontinuous.

[0114] Figure 5 is a schematic diagram of the power supply signal provided in the embodiment of this application. As shown in Figure 5, in the transmission period T1, the on duration T0 or on duration includes a transmission on time (Tx on or power on), that is, the power supply signal (such as a high-level signal) is continuously transmitted within T0 or on duration, which can also be understood as the power transmission module is continuously powered on within T0 or on duration. In addition, as shown in Figure 5, the off duration is T1-T0, that is, the power supply signal (such as a high-level signal) is continuously turned off within the off duration, which can also be understood as the power transmission module is continuously powered off within the off duration.

[0115] Figure 6 is a schematic diagram of the transmission cycle of the power supply signal provided in the embodiment of this application. As shown in Figure 6, in the transmission cycle T1, T0 or the on duration includes multiple transmission on times (Tx on or power on), that is, multiple discontinuous transmissions of the power supply signal (such as a high-level signal) within T0 or the on duration, which can also be understood as multiple discontinuous power-on transmission modules within T0 or the on duration. In addition, as shown in Figure 6, the off duration is (T1-T0), or the off duration includes (T1-T0) and the cumulative duration of the transmission off times (Tx off or power off) in T0.

[0116] It can be understood that the so-called transmit on time (Tx on or power on) refers to the duration of a single continuous transmission of a power signal (such as a high-level signal), which is the duration of the continuous power transmission module being turned on. As shown in Figure 5, one T0 or on duration can include one Tx on; as shown in Figure 6, one T0 or on duration can also include multiple transmit on times or multiple Tx on.

[0117] Therefore, the first duty cycle can be understood as the duty cycle of Tx on within a T0 or on duration, that is, the proportion of the effective time of power signal transmission within T0 or on duration. The second duty cycle can be understood as the duty cycle of Tx on within a transmission cycle, that is, the proportion of the effective time of power signal transmission within a transmission cycle. The third duty cycle can be understood as the proportion of Tx on within a power supply duration (charging operation / duration).

[0118] In some embodiments, the transmission time information of the power supply signal satisfies one or more of the following time requirements:

[0119] (1) The minimum value of the off duration is equal to the first duration;

[0120] (2) The maximum value of the on duration is equal to the second duration;

[0121] (3) The minimum value of the transmit off time (Tx off or power off) is equal to the third duration;

[0122] (4) The minimum value of the launch on time (Tx on or power on) is equal to the fourth duration;

[0123] (5) The first duty cycle is greater than or equal to the first threshold;

[0124] (6) The second duty cycle is greater than or equal to the second threshold;

[0125] (7) The third duty cycle is greater than or equal to the third threshold.

[0126] The time requirements for the transmission time information of the power supply signal mentioned above can be understood as the capability of the first device, which can be included in the power supply mode.

[0127] In some embodiments, the first device sends one or more of the aforementioned time requirements to the second or third device.

[0128] For S201, the first device transmits a power supply signal; wherein, the power supply signal is used to supply power to the second device, and the power supply signal is related to the power supply mode.

[0129] It is understandable that the first device initiates or triggers a charging operation / duration, controlling the power transmission module to power on or power off according to a configured or predefined charging mode. However, during the charging process of the first device, there may be a need for non-charging operations.

[0130] Based on this, further, in some embodiments, the first device transmits a power supply signal, including: the first device transmits a power supply signal according to a power supply mode and a predefined priority; wherein, the predefined priority includes the priority of power supply operation and one or more non-power supply operations; power supply operation refers to transmitting a power supply signal.

[0131] It is understood that in this embodiment, the first device transmits power supply signals according to the power supply mode and a predefined priority. That is, it transmits power supply signals according to the power supply mode and the predefined priority of power supply operation and non-power supply operation, thereby achieving reasonable processing of power supply operation and non-power supply operation. The first device transmits power supply signals according to the predefined priority and power supply mode, rather than according to the configured priority (i.e., the priority of power supply operation and non-power supply operation) and power supply mode. In this way, while achieving reasonable processing of power supply operation and non-power supply operation, it is beneficial to save the signaling overhead caused by configuring priority.

[0132] In some embodiments, among the predefined priorities, the power supply operation may have the highest priority, or the power supply operation may have a higher priority than the non-power supply operation. In other embodiments, among the predefined priorities, the priorities from highest to lowest are: first operation, power supply operation, and second operation; wherein the first operation and the second operation are non-power supply operations. The first device can control whether to perform a non-power supply operation during the power supply operation according to the predefined priorities.

[0133] That is, in some embodiments, the first device transmits a power supply signal according to the power supply mode and a predefined priority, including: if the first device needs to perform a non-power supply operation during the power supply operation, the first device transmits a power supply signal according to the power supply mode and a predefined priority.

[0134] It is understandable that the first device transmits power supply signals according to the power supply mode and predefined priorities. Compared to transmitting power supply signals according to configured priorities, this is beneficial for saving signaling overhead. The first device can control power supply and non-power supply operations according to the predefined priorities. Here, the configured priorities refer to the priorities between power supply operations and one or more non-power supply operations.

[0135] For example, non-powered operation includes one or more of the following:

[0136] (1) Paging;

[0137] (2) Voice communication;

[0138] (3) Data communication;

[0139] (4) Layer 1 Measurement;

[0140] (5) Layer 3 Measurement;

[0141] (6) Positioning measurement.

[0142] For example, Layer 1 measurement, Layer 3 measurement, or positioning measurement includes the transmission or reception of measurement reference signals for uplink or downlink channels. Layer 1 can be understood as physical layer measurement, and Layer 3 can be understood as radio resource control (RRC) layer measurement.

[0143] It should be noted that in the embodiments of this application, "power supply operation" can also be referred to as "power supply behavior" or "non-power supply operation" or "non-power supply behavior".

[0144] The following describes how the first device handles power supply operations and non-power supply operations during the power supply process, for different predefined priorities.

[0145] Example 1:

[0146] In Embodiment 1, among the predefined priorities, the power supply operation has the highest priority. In this case, if the first device needs to perform a non-power supply operation during the power supply operation, the first device transmits a power supply signal according to the power supply mode and the predefined priority, including:

[0147] During the power supply operation, the first device continuously transmits a power supply signal during the transmission on-time (Tx on or power on), and interrupts any necessary non-power supply operations during the transmission on-time; and,

[0148] During the power supply operation, the first device interrupts the required non-power supply operation during the transmission off time (Tx off or power off).

[0149] In other words, during the charging operation / duration, the first device is only allowed to perform charging operations, and non-charging operations (such as other communication services) are interrupted.

[0150] Figure 7 is a schematic diagram of the power supply operation and non-power supply operation provided in the embodiment of this application. As shown in Figure 7, during the process of the first device transmitting the power supply signal, non-power supply operations (such as Paging / voice or Data) are interrupted, whether during the transmission on time (Tx on or power on) or the transmission off time (Tx off or power off).

[0151] It should be noted that the power supply mode of the power supply signal shown in Figure 7 is the same as that shown in Figure 5, that is, a T0 or on duration can include a Tx on. Of course, the handling of non-power supply operations during the power supply operation described in Embodiment 1 also applies to the power supply mode shown in Figure 6, that is, non-power supply operations (such as Paging / voice or Data) are interrupted during both the transmit on time (Tx on or power on) and the transmit off time (Tx off or power off).

[0152] Example 2:

[0153] In Embodiment 2, within a predefined priority hierarchy, power supply operations have a higher priority than non-power supply operations. In this case, if a non-power supply operation is required during a power supply operation, the first device transmits a power supply signal according to the power supply mode and the predefined priority, including:

[0154] During the power supply operation, the first device continuously transmits power supply signals during the transmission on time (Tx on or power on) and interrupts the non-power supply operation that needs to be performed during the transmission on time (Tx on or power on).

[0155] During the power supply operation, the first device performs necessary non-power supply operations during the launch off time (Tx off / power off).

[0156] Figure 8 is a schematic diagram of the power supply and non-power supply operations provided in the embodiments of this application. As shown in Figure 8, during Tx on or power on, the first device is only allowed to perform power supply operations, and all other communication services are interrupted; during Tx off, the first device is allowed to perform sending and / or receiving signals on other communication links, such as receiving paging, voice, data, or measurement reference signals SSB / CSI-RS / PRS, etc.

[0157] Figure 8 is a schematic diagram of the processing of power supply and non-power supply operations provided in the embodiment of this application. As shown in Figure 8, during the process of the first device transmitting a power supply signal, non-power supply operations (such as Paging / voice or Data) are interrupted, whether during the transmission on time (Tx on or power on) or the transmission off time (Tx off or power off).

[0158] It should be noted that the power supply mode of the power supply signal shown in Figure 8 is the same as that shown in Figure 5, that is, a T0 or on duration can include a Tx on. Of course, the processing of non-power supply operations during the power supply operation described in Embodiment 2 is also applicable to the power supply mode shown in Figure 6.

[0159] Example 3:

[0160] For Embodiment 3, in the predefined priorities, the priorities from high to low are: first operation, power supply operation, and second operation; wherein, non-power supply operations include the first operation and the second operation; in this case, if the first device needs to perform a non-power supply operation during the power supply operation, the first device transmits a power supply signal according to the power supply mode and the predefined priorities, including:

[0161] If the first device needs to perform a first operation and / or a second operation during the power supply operation, it shall perform the first operation during the transmission on time (Tx on or power on) and / or transmit a power supply signal during the transmission on time.

[0162] Furthermore, during the power supply operation, the first device performs the first operation and / or the second operation within the transmission off time (Tx off or power off).

[0163] In other words, during the launch on time (Tx on or power on), the first device is allowed to perform power supply operations, and some non-power supply operations will be interrupted, while the higher-priority first operation (non-power supply operation) is not allowed to be interrupted.

[0164] For example, in some embodiments, the first operation includes paging and / or voice communication; the second operation includes data communication, layer 1 measurement, layer 3 measurement and / or positioning measurement.

[0165] Figure 9 is a schematic diagram of the power supply and non-power supply operations provided in the embodiments of this application. As shown in Figure 9, during the transmit on time (Tx on or power on), the first device is allowed to perform power supply operations, and some communication services will be interrupted, such as connected data and measurement reference signals SSB / CSI-RS / PRS, while idle paging and voice services have higher priority and are not allowed to be interrupted; during the transmit off time (Tx off or power off), the first device always allows other communication links to perform transmitting and receiving signals, such as idle receiving paging / voice, connected data, and measurement reference signals SSB / CSI-RS / PRS, etc.

[0166] It should be noted that the power supply mode of the power supply signal shown in Figure 9 is the same as that shown in Figure 5, that is, a T0 or on duration can include a Tx on. Of course, the processing of non-power supply operations during the power supply operation described in Embodiment 3 is also applicable to the power supply mode shown in Figure 6.

[0167] In Embodiment 3, if the first device needs to perform a first operation and / or a second operation during the power supply operation, it performs the first operation during the transmission on-time (Tx on or power on) and / or transmits a power supply signal during the transmission on-time; and the first device performs the first operation and / or the second operation during the transmission off-time (Tx off or power off) during the power supply operation. It is understood that multiple combinations are described here, and some of these combinations are described below:

[0168] In combination scheme 1: During the power supply operation, if the first device needs to perform a first operation, it performs the first operation during the transmission on time (Tx on or power on), and transmits a power supply signal during the transmission on time (Tx on or power on); and the first device performs the first operation during the transmission off time (Tx off or power off).

[0169] In combination scheme 2, if the first device needs to perform a first operation during the power supply operation, it performs the first operation and interrupts the transmission of the power supply signal during the transmission on time (Tx on or power on); and performs the first operation during the transmission off time (Tx off or power off).

[0170] In combination scheme 3, if the first device needs to perform a second operation during the power supply operation, it transmits a power supply signal and interrupts the second operation during the transmission on time (Tx on or power on); and if the first device performs a second operation during the transmission off time (Tx off or power off) during the power supply operation.

[0171] In combination scheme 4, if the first device needs to perform the first operation and the second operation during the power supply operation, it performs the first operation and transmits the power supply signal during the transmission on time (Tx on or power on) and interrupts the second operation; and if the first device needs to perform the first operation and the second operation during the transmission off time (Tx off or power off) during the power supply operation, it performs the first operation and the second operation.

[0172] In combination scheme 5, if the first device needs to perform a first operation and a second operation during the power supply operation, it performs the first operation during the transmission on time (Tx on or power on) and interrupts the second operation and the transmission of the power supply signal during the transmission on time (Tx on or power on); and the first device performs the first operation and the second operation during the transmission off time (Tx off or power off) during the power supply operation.

[0173] As in Embodiment 3 and further or additional embodiments of Embodiment 3 described above, during the power supply operation of the first device, the second operation is interrupted during the transmission on time (Tx on or power on).

[0174] Of course, in other embodiments, if the second operation to be performed is not allowed to be interrupted during the transmission on time (Tx on or power on), the second operation is performed during the transmission on time.

[0175] Figure 10 is a schematic diagram of the power supply operation and non-power supply operation provided in the embodiment of this application. As shown in Figure 10, if the first device receives a communication service that cannot be interrupted (such as connected data and measurement reference signals SSB / CSI-RS / PRS, etc.) within the transmission on time (Tx on or power on), then Tx on immediately switches to Tx off and resets the Tx off time to meet the minimum value requirement, that is, the minimum value of Tx off or power off (min Tx off length) is equal to the third duration (such as 200ms).

[0176] It should be noted that the power supply mode of the power supply signal shown in Figure 10 is the same as that shown in Figure 5, that is, a T0 or on duration can include a Tx on. Of course, the handling of non-power supply operations during the power supply operation shown in Figure 10 also applies to the power supply mode shown in Figure 6.

[0177] Example 4:

[0178] In Embodiment 4, in the predefined priorities, non-power supply operations have a higher priority than power supply operations; wherein, non-power supply operations include the first operation and the second operation; in this case, if the first device needs to perform a non-power supply operation during the power supply operation, the first device transmits a power supply signal according to the power supply mode and the predefined priorities, including:

[0179] If a non-power supply operation is required during the power supply operation of the first device, the non-power supply operation shall be performed during the transmission on time (Tx on or power on), and / or a power supply signal shall be transmitted during the transmission on time.

[0180] During the power supply operation, the first device performs a non-power supply operation during the transmission off time (Tx off or power off).

[0181] For example, in some embodiments, the first operation includes paging and / or voice communication; the second operation includes data communication, layer 1 measurement, layer 3 measurement and / or positioning measurement.

[0182] Figure 11 is a schematic diagram of the power supply and non-power supply operations provided in the embodiments of this application. As shown in Figure 11, during the transmit on time (Tx on or power on), the first device is allowed to perform power supply and non-power supply operations, such as connected data and measurement reference signals SSB / CSI-RS / PRS, etc., and idle paging and voice services have higher priority; during the transmit off time (Tx off or power off), the first device always allows other communication links to perform transmit and receive signals, such as idle paging / voice reception, connected data and measurement reference signals SSB / CSI-RS / PRS, etc.

[0183] It should be noted that the power supply mode of the power supply signal shown in Figure 11 is the same as that shown in Figure 5, that is, a T0 or on duration can include a Tx on. Of course, the processing of non-power supply operations during the power supply operation described in Embodiment 4 is also applicable to the power supply mode shown in Figure 6.

[0184] In this application embodiment, there is no limitation on whether the first device needs to interrupt the transmission of the power supply signal when performing the first operation and / or the second operation during the transmission on time (Tx on or power on). Of course, whether the transmission of the power supply signal needs to be interrupted is also related to the capability of the first device.

[0185] In some embodiments, the first device interrupts the transmission of the power supply signal when performing a first operation and / or a second operation during the transmission on time (Tx on or power on); the first device continuously transmits the power supply signal when not performing the first operation and / or the second operation during the transmission on time (Tx on or power on).

[0186] In other embodiments, the first device does not interrupt the transmission of the power supply signal when performing the first operation and / or the second operation during the transmission on time (Tx on or power on).

[0187] For Embodiments 1 to 4 and further or additional embodiments of each embodiment, in some embodiments, after the first device completes the required non-power supply operation, it continues to transmit a power supply signal in the power supply mode. That is, performing a non-power supply operation during one or more Tx on or Tx off periods will not affect the start time and length of subsequent Tx on and Tx off, and the subsequent power supply operation will still be performed in the manner defined by the power supply mode.

[0188] It is understood that the above embodiments one to four and further or additional embodiments describe a method for the first device to handle non-power supply operations that need to be performed during the power supply operation. This method can be understood as different capabilities of the first device, and the first device can report one or more of these capabilities to the network or notify the second device.

[0189] For Embodiments 2 to 4 and further or additional embodiments of each embodiment, coexistence between power supply operation and non-power supply operation (i.e., other communication services) is realized, thereby satisfying the power supply demand while also satisfying the demand for some communication services, so that power supply operation and some other communication services can coexist reasonably in the first device.

[0190] It is understood that in the wireless communication methods provided in one or more of the above embodiments, the non-powered operation may affect the normal operation of the powered mode. That is, the transmission of the power supply signal may be interrupted during the transmission on time (Tx on or power on), thereby affecting the power supply to the second device. Of course, the transmission of the power supply signal may also be interrupted due to other factors.

[0191] Based on this, in some embodiments, the wireless communication method provided in this embodiment further includes: a first device reporting a first indication to a higher layer or a third device through the physical layer; the first indication is used to indicate the power supply result to the second device; the first indication is related to the execution of the power supply mode by the first device.

[0192] It is understandable that the first device reports the power supply results to the higher or third device through the physical layer. This facilitates the monitoring of the power supply results of the first device by the higher or third device, thereby enabling timely adjustment of the power supply mode of the first device and ensuring that the power supply results of the first device meet the requirements.

[0193] Furthermore, in some embodiments, the first indication is used to indicate whether the power supply to the second device is adequate, or the first indication is used to indicate whether the power supply link to the second device has failed.

[0194] For higher layers, by way of example, in some embodiments, higher layers include one or more of the RRC layer, NAS layer, and application layer.

[0195] For example, in some embodiments, the third device includes network devices, such as base stations.

[0196] Optionally, in some embodiments, a higher-level or third-level device may adjust the power supply mode of the first device based on one or more first instructions sent by the first device.

[0197] That is, in some embodiments, the wireless communication method provided in this embodiment further includes: a first device transmitting a power supply signal according to a new power supply mode indicated by a higher layer; wherein the new power supply mode is determined based on one or more first instructions.

[0198] In other embodiments, the wireless communication method provided in this embodiment further includes: a first device receiving first configuration information sent by a third device, the first configuration information being used to indicate a new power supply mode; the first device transmitting a power supply signal according to the new power supply mode indicated by the first configuration information; wherein the new power supply mode is associated with one or more first indications, and further, the new power supply mode is determined based on one or more first indications.

[0199] It is understandable that whether the first device's power supply to the second device meets the standard, that is, the power supply result of the first device to the second device (i.e., power supply effect, power supply efficiency, etc.), may be affected by non-power supply operations or other factors.

[0200] Optionally, in some embodiments, a first indication for indicating whether the power supply to the second device is adequate is related to the first device's performance of the power supply mode over one or more charging operation / durations.

[0201] Furthermore, the execution of the power supply mode by the first device during one or more charging operations / durations includes one or more of the following:

[0202] (1) Execution status of launch activation time (Tx on or power on);

[0203] (2) Execution status of the launch shutdown time (Tx off or power off);

[0204] (3) Execution status of enabling duration (on duration).

[0205] For example, in some embodiments, the execution of the transmit on time (Tx on or power on) includes one or more of the following:

[0206] (1) First count: The first count refers to the cumulative number of times the launch on time (Tx on or power on) is interrupted within one or more charging operation / durations.

[0207] (2) Second count: The second count refers to the cumulative number of times the launch on time (Tx on or power on) is not interrupted within one or more charging operation / durations.

[0208] (3) First duration: The first duration refers to the cumulative transmission duration of the power supply signal corresponding to the second number, that is, the cumulative duration of Tx on or power on that is not interrupted within one or more power supply durations (charging operation / duration);

[0209] (4) Second duration: The second duration refers to the cumulative transmission duration of the power supply signal within one or more power supply durations (charging operation / duration), that is, the actual cumulative duration (i.e., effective duration) of the power supply signal (such as a high-level signal) transmitted by the first device within one or more power supply durations (charging operation / duration).

[0210] It is understandable that the first count refers to the cumulative number of times Tx on or power on is interrupted within one or more charging operations / durations. An interruption of Tx on or power on can be understood as a switch from Tx on or power on to Tx off or power off. For example, the first device interrupts the transmission of the power supply signal when performing a first operation and / or a second operation during the transmission activation time (Tx on or power on).

[0211] In one possible implementation, a counter (which we call the first counter) can be used to accumulate the number of times Tx on or power on is interrupted within one or more charging operations / durations.

[0212] Figure 12 is a schematic diagram illustrating the cumulative number of interruptions of Tx on or power on according to an embodiment of this application. As shown in Figure 12, when the first Tx on or power on is interrupted, the value of the first counter is 1, i.e., N = 1; when the fourth Tx on or power on is interrupted, the value of the first counter is incremented by 1, i.e., N = 2; and so on.

[0213] The second count, in contrast to the first count, refers to the cumulative number of times the transmission on-time (Tx on or power on) was not interrupted within one or more charging operation / durations. "Tx on or power on not being interrupted" means that the first device continuously transmits a charging signal without interruption within Tx on or power on; that is, the duration of a single continuous transmission of a charging signal (such as a high-level signal) by the first device is equal to the length of Tx on or power on.

[0214] In one possible implementation, a counter (which we call the second counter) can be used to accumulate the number of times Tx on or power on is not interrupted within one or more charging operations / durations.

[0215] Figure 13 is a schematic diagram illustrating the cumulative number of times Tx on or power on is not interrupted according to an embodiment of this application. As shown in Figure 13, when the first Tx on or power on is interrupted and the second Tx on or power on is not interrupted, the value of the second counter is 1, i.e., N = 1; when the third Tx on or power on is not interrupted, the value of the second counter is incremented by 1, i.e., N = 2; and so on.

[0216] For example, in some embodiments, the execution of the transmit off time (Tx off or power off) includes one or more of the following:

[0217] (1) The third count refers to the cumulative number of times the transmission power signal is turned off within one or more charging operation / durations;

[0218] (2) Third duration: The third duration refers to the cumulative transmission duration of the power supply signal being turned off within one or more charging operation / durations. That is, the cumulative duration of Tx off or power off within one or more charging operation / durations. Alternatively, it can be understood as the cumulative duration of the power transmission module being turned off to interrupt the transmission of power supply signals (such as high-level signals) within one or more charging operation / durations.

[0219] It is understood that the third count refers to the cumulative number of times Tx is off or power is off within one or more charging operations / durations. Optionally, in some embodiments, the cumulative number in the third count also includes the number of times Tx is switched from on or power on to off or power off.

[0220] In one possible implementation, a counter (which we call the third counter) can be used to accumulate the number of times Tx off or power off occurs within one or more charging operations / durations.

[0221] Figure 14 is a schematic diagram illustrating the cumulative number of Tx off or power off operations provided in an embodiment of this application. As shown in Figure 14, after the first Tx off or power off operation is completed, the value of the third counter is 1, i.e., N = 1; after the second Tx off or power off operation is completed, the value of the third counter is incremented by 1, i.e., N = 2; and so on.

[0222] For example, in some embodiments, the execution of the activation duration includes one or more of the following:

[0223] The fourth count is the cumulative number of times the on-duration period is interrupted within one or more charging operation / duration periods.

[0224] The fifth count is the cumulative number of times the on-duty period is not interrupted within one or more charging operation / durations.

[0225] As mentioned earlier, the on-duration refers to the total duration of a single continuous or multiple discontinuous transmission of power signals within a transmission cycle. The length of one on-duration can be equal to the length of one Tx on or power on signal, and one on-duration can also include multiple Tx on or power on signals. In some embodiments, interrupting one or more Tx on or power on signals within the on-duration is referred to as the on-duration being interrupted. Conversely, in some embodiments, the fact that all Tx on or power on signals within an on-duration are not interrupted is referred to as the on-duration not being interrupted.

[0226] In one possible implementation, a counter (which we call the fourth counter) can be used to accumulate the number of times the duration is interrupted within one or more charging operations / durations.

[0227] In one possible implementation, a counter (which we call the fifth counter) can be used to accumulate the number of times the duration is not interrupted within one or more charging operations / durations.

[0228] Figure 15 is a schematic diagram illustrating the cumulative number of interruptions during the on-duration event provided in an embodiment of this application. As shown in Figure 15, in the first on-duration event, two Tx on or power on events are interrupted, so the value of the fourth counter is 1, i.e., N = 1; in the second on-duration event, two Tx on or power on events are interrupted, so the value of the fourth counter is incremented by 1, i.e., N = 2; and so on.

[0229] Figure 16 is a schematic diagram illustrating the cumulative number of uninterrupted on-duration events according to an embodiment of this application. As shown in Figure 16, in the first on-duration event, there is a complete and uninterrupted Tx on or power on event, so the value of the fifth counter is 1, i.e., N = 1; in the second on-duration event, there is a complete and uninterrupted Tx on or power on event, so the value of the fifth counter is 2, i.e., N = 2; in the second on-duration event, there is an interrupted Tx on or power on event, so the value of the fifth counter is 2, i.e., N = 2; and so on.

[0230] Figure 17 is a schematic diagram of the cumulative number of uninterrupted on-duration times provided in an embodiment of this application. As shown in Figure 17, in the first on-duration, two of the Tx on or power on are interrupted, so the value of the fifth counter is 0, i.e., N = 0; in the second on-duration, each Tx on or power on is complete and uninterrupted, so the value of the fifth counter is 1, i.e., N = 1; and so on.

[0231] In this embodiment, a first value can be used to indicate that the power supply to the second device is insufficient. We can also refer to this first indication (OOS) as "out of sync" or "out of service," etc. Insufficient power supply to the second device can also be understood as insufficient or substandard charging efficiency.

[0232] In some embodiments, when a first condition is met, the first indication includes a first value indicating that the power supply to the second device is insufficient, or the first value indicating that the power supply link to the second device has failed; wherein the first condition includes one or more of the following conditions:

[0233] (1) The first count is greater than or equal to the corresponding threshold;

[0234] (2) The second number is less than or equal to the corresponding threshold;

[0235] (3) The first duration is less than or equal to the corresponding threshold;

[0236] (4) The proportion of the first duration in the cumulative duration of one or more charging operation / durations is less than or equal to the corresponding threshold;

[0237] (5) The second duration is less than or equal to the corresponding threshold;

[0238] (6) The proportion of the second duration in the cumulative duration of one or more charging operation / durations is less than or equal to the corresponding threshold;

[0239] (7) The third number is greater than or equal to the corresponding threshold;

[0240] (8) The third duration is greater than or equal to the corresponding threshold;

[0241] (9) The proportion of the third duration in the cumulative duration of one or more charging operation / durations is greater than or equal to the corresponding threshold;

[0242] (10) The proportion of the third duration in the second duration is greater than or equal to the corresponding threshold;

[0243] (11) The fourth time is greater than or equal to the corresponding threshold;

[0244] (12) The fifth time is less than the corresponding threshold.

[0245] For example, if the first device meets one or more of the first conditions mentioned above in its execution of the power supply mode during a power supply operation / duration, the first value indicates that the power supply to the second device is not up to standard.

[0246] For example, if the first device performs the power supply mode in a power supply mode for a number of power supply operations / durations and meets one or more of the first conditions mentioned above, the first value indicates that the power supply link to the second device has failed.

[0247] In one possible implementation, the higher-level equipment or the third-level equipment adopts different handling strategies for the two monitoring results: "the power supply to the second equipment is insufficient" and "the power supply link to the second equipment has failed." For example, the adjustment strategy for the power supply mode of the first equipment differs depending on whether the monitoring result is "the power supply to the second equipment is insufficient" or "the power supply link to the second equipment has failed."

[0248] In the embodiments of this application, a second value can be used to indicate that the power supply to the second device meets the standard. We can also refer to the first indication that the power supply to the second device meets the standard as "in sync(IS) indication" or "in of service," etc. The power supply to the second device meeting the standard can also be understood as the charging efficiency of the second device being sufficient or meeting the standard, or as the power supply to the second device being effective.

[0249] In some embodiments, when the second condition is met, the first indication includes a second value indicating that the power supply to the second device is satisfactory, or the second value indicating that the power supply link to the second device is successful; wherein the second condition includes one or more of the following conditions:

[0250] (1) The first number is less than the corresponding threshold;

[0251] (2) The second number is greater than the corresponding threshold;

[0252] (3) The first duration exceeds the corresponding threshold;

[0253] (4) The proportion of the first duration in the cumulative duration of one or more charging operation / durations is greater than the corresponding threshold;

[0254] (5) The second duration exceeds the corresponding threshold;

[0255] (6) The proportion of the second duration in the cumulative duration of one or more power supply durations is greater than the corresponding threshold;

[0256] (7) The third number is less than the corresponding threshold;

[0257] (8) The third duration is less than the corresponding threshold;

[0258] (9) The proportion of the third duration in the cumulative duration of one or more power supply durations is less than the corresponding threshold;

[0259] (10) The proportion of the third duration in the second duration is less than the corresponding threshold;

[0260] (11) The fourth time is less than the corresponding threshold;

[0261] (12) The fifth time is greater than or equal to the corresponding threshold.

[0262] For example, if the first device meets one or more of the second conditions mentioned above in its execution of the power supply mode during a power supply operation / duration, the first value indicates that the power supply to the second device is not up to standard.

[0263] For example, if the first device satisfies one or more of the second conditions mentioned above in the execution of the power supply mode during multiple power supply operations / durations, the first value indicates that the power supply link to the second device is successful.

[0264] In one possible implementation, the higher-level equipment or the third-level equipment adopts different processing strategies for the two monitoring results: "the power supply to the second equipment meets the standards" and "the power supply link to the second equipment is successful." For example, the adjustment strategy for the power supply mode of the first equipment differs depending on whether the monitoring result is "the power supply to the second equipment meets the standards" or "the power supply link to the second equipment is successful."

[0265] In some embodiments, the wireless communication method provided in this embodiment further includes: when a first device determines a first instruction, setting the values ​​of one or more counters used to statistically analyze the execution status to zero. For example, the first to fourth counters mentioned above.

[0266] In this embodiment of the application, the first device may report the first instruction by triggering, or it may report the first instruction periodically.

[0267] In some embodiments, the first device reports a first indication to a higher layer or a third device through the physical layer, including: when a first condition is met, the first device reports a first indication including a first value to a higher layer or a third device through the physical layer.

[0268] In some embodiments, the first device reports a first indication to a higher layer or a third device through the physical layer, including: if a second condition is met, the first device reports a first indication including a second value to a higher layer or a third device through the physical layer.

[0269] In other embodiments, the first device reports a first instruction to a higher layer or a third device through the physical layer, including: the first device periodically reporting the first instruction to a higher layer or a third device through the physical layer.

[0270] As mentioned earlier, in some embodiments, for the execution of the power supply mode by the first device within one power supply operation / duration, the first indication reported may be an indication of whether the power supply to the second device is up to standard; for the execution of the power supply mode by the first device within multiple power supply operation / durations, the first indication reported may be an indication of whether the power supply link to the second device has failed.

[0271] Of course, in other embodiments, the first indication reported regarding the execution of the power supply mode by the first device over multiple power supply durations may also be an indication of whether the power supply to the second device is up to standard.

[0272] The following describes another implementation of determining whether the power supply link of the second device has failed.

[0273] In some embodiments, the wireless communication method provided in this embodiment further includes: a first device reporting a second indication to a higher layer or a third device through the physical layer; the second indication is used to indicate whether the power supply link has failed within a monitoring time window; wherein, the monitoring time window includes one or more charging operation / durations.

[0274] It is understandable that the first device reports whether the power supply link has failed to the higher or third device through the physical layer. This facilitates the higher or third device to monitor the power supply results of the first device, thereby making it easier to adjust the power supply mode of the first device in a timely manner, so that the power supply results of the first device meet the requirements.

[0275] Optionally, in some embodiments, a higher-level or third-level device may adjust the power supply mode of the first device based on one or more second instructions sent by the first device.

[0276] That is, in some embodiments, the wireless communication method provided in this embodiment further includes: a first device transmitting a power supply signal according to a new power supply mode indicated by a higher layer; wherein the new power supply mode is associated with one or more second indications, and further, the new power supply mode is determined based on one or more second indications.

[0277] In other embodiments, the wireless communication method provided in this embodiment further includes: a first device receiving second configuration information sent by a third device, the second configuration information being used to indicate a new power supply mode; the first device transmitting a power supply signal according to the new power supply mode indicated by the second configuration information; wherein the new power supply mode is associated with one or more second indications, and further, the new power supply mode is determined based on one or more second indications.

[0278] In the embodiments of this application, the new power supply mode indicated by the first configuration information and the second configuration information may be the same or different.

[0279] In some other embodiments, the first device may determine the power supply mode (e.g., adjust or set) based on the response of the second device; wherein the response of the second device is related to the power supply signal.

[0280] In the embodiments of this application, the response of the second device can also be understood as the feedback of the second device to the power supply signal. Further, in some embodiments, the response of the second device includes one or more of the following information:

[0281] Cold start time of the second device;

[0282] The hot start time of the second device;

[0283] For measurement information of the power supply signal, such as the received signal strength;

[0284] The time interval at which the second device sends data packets;

[0285] First instruction;

[0286] Second instruction.

[0287] The following section further describes possible implementations for determining whether the power supply link to the second device has failed.

[0288] In some embodiments, if a third condition is met, the second indication includes a third value indicating a power supply link failure; wherein the third condition includes one or more of the following conditions:

[0289] (1) The cumulative number of first indications including the first value within the monitoring time window is greater than or equal to the corresponding threshold; wherein, the first value indicates that the power supply to the second device is substandard during one or more power supply durations;

[0290] (2) The cumulative number of first indications including the second value within the monitoring time window is less than the corresponding threshold; wherein the second value indicates that the power supply to the second device meets the standard within one or more power supply durations.

[0291] In some embodiments, when a fourth condition is met, the second indication includes a fourth value indicating that the power supply link is successful; wherein the fourth condition includes one or more of the following conditions:

[0292] (1) The cumulative number of first indications including the first value within the monitoring time window is less than the corresponding threshold; wherein, the first value indicates that the power supply to the second device is substandard during one or more power supply durations;

[0293] (2) The cumulative number of first indications including the second value within the monitoring time window is greater than or equal to the corresponding threshold; wherein the third value indicates that the power supply to the second device meets the standard within one or more power supply durations.

[0294] In one possible implementation, a counter (which we call the sixth counter) can be used to accumulate the cumulative number of the first indications, including the first value, determined within the monitoring time window.

[0295] In one possible implementation, a counter (which we call the seventh counter) can be used to accumulate the cumulative number of the first indication, including the second value, determined within the monitoring time window.

[0296] In some embodiments, when a second instruction is determined, the first device sets the value of a counter used to count one or more cumulative numbers of the first instruction to zero.

[0297] In this embodiment of the application, the first device may report the second instruction by triggering, or it may report the second instruction periodically.

[0298] In some embodiments, the first device reports a second indication to a higher layer or a third device through the physical layer, including: if a third condition is met, the first device reports a second indication including a third value to a higher layer or a third device through the physical layer.

[0299] In some embodiments, the first device reports a second indication to a higher layer or a third device through the physical layer, including: if a fourth condition is met, the first device reports a second indication including a fourth value to a higher layer or a third device through the physical layer.

[0300] In other embodiments, the first device reports a second instruction to a higher layer or a third device through the physical layer, including: the first device periodically reporting the second instruction to a higher layer or a third device through the physical layer.

[0301] The wireless communication method provided in the embodiments of this application has been introduced above. To facilitate understanding of the embodiments of this application, the following describes possible implementation schemes of the wireless communication method applicable to the embodiments of this application, taking the first device as the power supply device and the second device as an A-IoT device as an example.

[0302] A-IoT devices (or Ambient IoT devices) are low in complexity and cost, and can be maintenance-free and battery-free. They can be divided into passive zero-power terminals, semi-passive zero-power terminals, and active zero-power terminals, etc. They obtain energy for communication by harvesting energy from the environment (such as radio frequency energy, light energy, heat energy, mechanical energy, kinetic energy, etc.). In terms of communication methods, they can support backscattering and / or active transmission communication methods.

[0303] The power supply device provides a power signal to wirelessly charge / power A-IoT devices. The A-IoT device collects and stores sufficient energy and then begins to send or receive communication signals. During the power supply process, in addition to the strength of the transmitted power signal, its pattern, i.e., the Tx on / off period, the length and ratio of the on duration and off duration, all have a significant impact on the energy collection efficiency and cold / warm start time of the A-IoT device. On the one hand, the charging and discharging efficiency and strategy of the A-IoT device must be considered; on the other hand, the coexistence of the power supply device's own radio frequency and baseband processing capabilities, and other communication services besides A-IoT services must also be met. Therefore, a reasonable design for the Tx on / off function of the power supply device is needed to monitor and indicate the power supply status and results, so as to adjust the power supply and normal communication to achieve reasonable coexistence and meet the specified requirements for emission heat and radiation.

[0304] 1) As shown in Figure 18, the power supply device 1801 provides a power supply signal on a certain frequency point or frequency band to the A-IoT device 1802, and the A-IoT device 1802 transmits communication signals (such as broadcasting signals via Bluetooth) by active transmission or passive reflection; the power supply device 1801 can be a terminal or network device or other energy source node;

[0305] 2) The network configures the power supply pattern (i.e. power supply mode) for the power supply device, or the power supply device selects and adjusts the power supply pattern to enable the power supply, or the power supply device sets or adjusts the power supply pattern based on the response of the A-IoT device (such as response latency or period, more specifically, it can be divided into cold start or hot start time).

[0306] The pattern includes at least one of the following: the cycle of the switch that sends the power signal (i.e., the transmission cycle of the power signal), the total duration of the switch (i.e., the duration of power supply), the on ratio (such as the first duty cycle, the second duty cycle, the third duty cycle) or the off ratio, the duration of one on (i.e., Tx on or power on) or the duration of one off (i.e., Tx off or power off).

[0307] For example, the configuration of the power supply signal (Tx) for a power supply device can be: rfid_tx_on(power, center_freq, duration, duty_cycle, hopping_config); where power represents the transmit power of the power supply signal, center_freq represents the center frequency / center point of the power supply signal, duration represents the duration of the power supply signal, duty_cycle represents the duty cycle of the power supply signal, and hopping_config represents the frequency hopping configuration of the power supply signal. For example, as shown in Figure 4, within a power supply duration (charging operation / duration), the power supply signal is allowed to hop frequencies between multiple frequency points in a competitive or random manner.

[0308] Specifically, regarding the time requirements for Tx on / off in Pattern, the following methods can be used:

[0309] Optionally, the minimum Tx off period (i.e., T1-T0) is 200ms, 300ms, or 500ms, etc.; it can be a UE capability, which characterizes the minimum interval requirement for the UE to continuously provide power at this frequency point, for receiving other communication data, radio frequency or baseband resource processing or adjustment, etc.

[0310] Another approach 2 is that, optionally, the maximum Tx on period (T0) is 500ms, 700ms, 800ms, etc.; it can also correspond to UE capability, which represents the longest continuous power supply time of the UE in this frequency band, used to ensure that the UE's Tx link does not exceed the overheating / PA junction temperature requirements, radiation requirements, and the maximum interruption time requirements for other communication services.

[0311] Another method, 3, stipulates that the duty cycle of Tx on in Tx on / off cannot exceed 75%, 50%, 25%, 12.5%, etc.; and the minimum length of a single continuous Tx off within a cycle (min Tx off length, T1-T0) is 200ms, 100ms, 4ms, or 1ms, etc. In method 3, the time outside of Tx off can be called on duration, which can be continuous Tx on (as shown in Figure 5) or a periodic Tx on / off with a certain duty cycle (as shown in Figure 6), for example, Tx on accounts for 50%, and on / off at the slot / ms level.

[0312] 3) The power supply equipment starts the power supply operation (charging operation / duration), and controls Tx on / off according to the configured or preset pattern.

[0313] One implementation method is as shown in Figure 7, where the power supply device is only allowed to perform power supply operations during the charging operation / duration, and other communication services are interrupted; where other communication services can be understood as an example of non-power supply operations.

[0314] Another implementation method 2 is, as shown in Figure 8, that during the time Tx on, the power supply device is only allowed to perform power supply operations, and all other communication services are interrupted;

[0315] During the Tx off period, the power supply device allows other communication links to perform signal transmission and reception, such as receiving paging, data, measurement reference signals SSB / CSI-RS / PRS, etc.

[0316] Another implementation method 3 is as shown in Figure 9. During the Tx on time, the power supply device is allowed to perform power supply operations, and some communication services will be interrupted, such as data and measurement reference signals SSB / CSI-RS / PRS in the connected state, while paging and voice services in the idle state have higher priority and are not allowed to be interrupted.

[0317] During the Tx off period, the power supply device always allows other communication links to perform signal transmission and reception, such as receiving paging / voice in idle state, data and measurement reference signals SSB / CSI-RS / PRS in connected state, etc.

[0318] Optionally, for implementation method 3, in some embodiments, if a communication service that cannot be interrupted (such as connected state data and measurement reference signals SSB / CSI-RS / PRS, etc.) is received during the Tx on time, the time for immediately switching Tx on to Tx off and resetting Tx off must meet the minimum Tx off length (e.g., 200ms), see Figure 10.

[0319] In some embodiments, the priority of Tx on compared to other services is, in one optional transmission priority order: ACQ / Paging > Voice > "Tx on" > Data. This priority can be the default, or it can be reported or notified to the base station or A-IoT device by the UE through UE preference signaling. The UE is an example of a power supply device.

[0320] The above-mentioned implementation methods can represent different capabilities of the power supply equipment; they can also report or notify the network or A-IoT devices.

[0321] 4) Monitoring of power supply equipment Tx on / off

[0322] One method for calculating the monitoring indication is as shown in Figure 12. Each time Tx on is interrupted, the count is incremented by 1. Before the charging operation ends, if the accumulated N is greater than the threshold N1 (e.g., N=5, N1=4), then the charging efficiency is considered insufficient or substandard, and an OOS indication is sent.

[0323] Another method for calculating the monitoring indication is as follows: each time Tx on is interrupted, it immediately enters Tx off until the end of the Tx off length (as shown in Figure 10). The UE counts the time of this Tx on length as sub-Ton_1. After the next Tx on, the same logic is followed, counting sub-Ton_2, or the total time of Tx on as sub-Ton_1+sub-Ton_2, ..., sub-Ton_n, or the total time of Tx on as sub-Ton_1+...+sub-Ton_n. Here, the UE can be an example of a power supply device.

[0324] If the total accumulated Tx on time is less than the threshold Tx_on_threthold before the charging operation ends, the charging efficiency is considered insufficient or substandard, and an OOS indication is reported.

[0325] Another method for monitoring and indicating calculation is as shown in Figure 14. Each time the Tx off counter is incremented by 1, if the cumulative number of Tx off N is greater than the threshold N2 before the end of the charging operation, it is considered that the charging efficiency is insufficient or substandard, and an OOS indication is reported.

[0326] Another method for calculating the monitoring indication is as shown in Figure 14. Each time the Tx off counter N is incremented by 1; before the end of the charging operation, if the proportion of the total number of Tx off N3*Tx_off_length to the charging duration is greater than X, then the charging efficiency is considered insufficient or substandard, and an OOS indication is reported.

[0327] Another method for monitoring and calculating the indication is as shown in Figure 15. Each time the ON duration is interrupted, the counter N is incremented by 1. Before the end of the charging operation, if the cumulative number of Tx on interruptions exceeds N4, or if the ratio of N*Tx_off_length to charging duration*Tx_on_dutyclcyle (effective Tx on time) is greater than Y, then the charging efficiency is considered insufficient or substandard, and an OOS indication is reported.

[0328] Another method for monitoring and indicating calculation is as shown in Figure 16 or Figure 17: if each Tx on length is complete and uninterrupted during a charging duration, the counter P is incremented by 1, indicating that the charging has met the standard, and an in-sync indication is reported.

[0329] Another method for calculating the monitoring indication is, as shown in Figure 16, the proportion of occurrences of complete Tx on length excluding interruptions in a charging duration, or the total duration, exceeds the configured duty cycle threshold default proportion (e.g., 50%) or duty_cycle. The counter P is incremented by 1, indicating that the charging is considered to have met the standard, and an OOS indication is reported.

[0330] It should be noted that the OOS and IS indicators mentioned above, also known as out of power or in power indicators, respectively indicate whether the power supply is effective during a charging duration.

[0331] 5) The terminal's physical layer instructs higher layers to report indicator instructions periodically or via triggering within the configured or specification-required monitoring window (i.e., the monitoring time window), based on the network or terminal's own configured pattern. Specifically,

[0332] a) Methods for indicating Tx power failure and power supply link failure (RLF):

[0333] - Within the monitoring time window M1, count the number of indicators for each "Tx off" or the total duration of Tx off. If the number of times Q1 or the total duration Q2 is exceeded, report the indication to higher level, indicating low power supply level; A-IoT device charging failure or link failure RLF.

[0334] or,

[0335] - Within the monitoring time window M2, calculate whether the total time of Tx on is lower than a certain proportion Q3 or threshold Q4, indicating a low power supply level; A-IoT devices fail to charge or still experience link failure (RLF).

[0336] or

[0337] - As shown in Figure 19, within the monitoring time window M3, the indicator of "OOS" for each charging duration is counted, and the counter is incremented by one. When the count exceeds Q5, an indication is reported to the higher layer, indicating that the power supply has failed; the A-IoT device is not charging successfully or the link connection is still failed (RLF).

[0338] b) Indicating that Tx power meets the standard, and the power supply link is normal or has returned to normal:

[0339] As shown in Figure 19, the number of times Tx on length is completed within the monitoring time window M1 is counted. If the indicator shows "IS" for P consecutive times, an indication is reported to the higher level, indicating that the power supply is normal or restored.

[0340] It is understood that, in one or more of the above embodiments, a method for power supply monitoring and indication is provided to determine the power supply effect of the power supply device on the A-IoT device, so as to better control the power supply scheme, meet the communication requirements of the power supply device, and ensure the power supply needs of A-IoT.
