[0030] The following will clearly and completely describe the technical solutions of this disclosure in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of this disclosure, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of this disclosure without making any creative efforts shall fall within the scope of protection of this disclosure.

[0031] It should be noted that in this disclosure, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described in this disclosure as "exemplary" or "for example" should not be construed as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0032] In the following, the terms "first," "second," etc. are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the quantity of the technical features indicated. Therefore, a feature specified as "first," "second," etc. may explicitly or implicitly include one or more of the features.

[0033] In the description of this disclosure, unless otherwise specified, " / " means "or." For example, A / B can mean A or B. "And / or" herein is merely a description of an association relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can mean: only A, only B, and both A and B. Furthermore, "at least one" means one or more, and "a plurality" means two or more.

[0034] In wireless power delivery systems, channel measurement is typically achieved by measuring a reference signal. However, charging devices that lack or disable signal detection cannot demodulate the reference signal and therefore cannot measure the channel.

[0035] The communication method provided by the embodiments of the present disclosure can be applied to systems of various communication formats. For example, the communication method provided by the embodiments of the present disclosure can be applied to systems including, but not limited to, long-term evolution (LTE) systems, various versions based on LTE evolution, fifth-generation (5G) systems, and other next-generation communication systems. In addition, the communication method provided by the embodiments of the present disclosure can also be applied to future-oriented communication systems.

[0036] As shown in FIG1 , a wireless energy supply system is provided in an embodiment of the present disclosure. The wireless energy supply system includes an energy supply device 10 and a charging device 20 .

[0037] The energy supply device 10 is used to supply energy to the energy charging device 20 by sending an energy signal to the energy charging device 20. Accordingly, the energy charging device 20 is used to receive the energy signal sent by the energy supply device 10 and convert the energy signal into its own electrical energy.

[0038] In the embodiment of the present disclosure, one or more wireless charging technologies can be used between the energy supply device 10 and the charging device 20, such as wireless charging technology based on electromagnetic induction, wireless charging technology based on magnetic field resonance, and wireless charging technology based on radio waves, without limitation.

[0039] In the embodiment of the present disclosure, the energy supply device 10 and the charging device 20 may comply with one or more wireless charging standards, such as the Qi standard, the Power Matters Alliance (PMA) standard, and the Alliance for Wireless Power (A4WP) standard, without limitation.

[0040] In some embodiments, the energy supply device 10 can transmit energy signals via directional beams to concentrate the radiated energy of the energy signals, thereby increasing the coverage distance of the energy signals. When the energy signals are transmitted via directional beams, beam training can be performed between the energy supply device 10 and the charging device 20 to determine the optimal beam. This beam training can include beam training at the transmitting end (referred to as transmit beam training) and beam training at the receiving end (referred to as receive beam training).

[0041] In some embodiments, the charging device 20 may also have a communication function. Based on this, the energy supply device 10 and the charging device 20 can communicate with each other. As an example, the charging device 20 can send energy signal-related demand information to the energy supply device 10. As another example, the energy supply device 10 can send energy signal-related information (such as the energy signal period) to the charging device 20.

[0042] In some embodiments, based on the fact that the charging device 20 has a communication function, the charging device 20 may enable discontinuous reception (DRX) to save energy.

[0043] In the embodiments of the present disclosure, there is no limitation on the product forms of the energy supply device 10 and the energy charging device 20. As an example, as shown in FIG1 , the energy supply device 10 may be a base station, and the energy charging device 20 may be a terminal.

[0044] In some embodiments, the base station can be a base station or an evolved base station (eNB or eNodeB) in long term evolution (LTE), long term evolution advanced (LTEA), a base station device in a 5G network, or a base station in a future communication system, etc. The base station can include various macro base stations, micro base stations, home base stations, wireless remote stations, reconfigurable intelligent surfaces (RISs), routers, wireless fidelity (WIFI) devices and other network side devices.

[0045] In some embodiments, the terminal can be a device with wireless transceiver function. The terminal can be a mobile phone, a tablet computer, a computer with wireless transceiver function, a virtual reality (VR) terminal, an augmented reality (AR) terminal, a wireless terminal in industrial control, a wireless terminal in unmanned driving, a wireless terminal in remote medical, a wireless terminal in smart grid, a wireless terminal in transportation safety, a wireless terminal in smart city, a wireless terminal in smart home, etc. The embodiments of the present disclosure do not limit the application scenarios. The terminal can sometimes also be referred to as a user, user equipment (UE), access terminal, UE unit, UE station, mobile station, mobile station, remote station, remote terminal, mobile device, UE terminal, wireless communication equipment, UE agent or UE device, etc., and the embodiments of the present disclosure do not limit this.

[0046] The application scenarios of the embodiments of the present disclosure are not limited. The system architecture and business scenarios described in the embodiments of the present disclosure are intended to more clearly illustrate the technical solutions of the embodiments of the present disclosure and do not constitute a limitation on the technical solutions provided by the embodiments of the present disclosure. Those skilled in the art will appreciate that with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided by the embodiments of the present disclosure are equally applicable to similar technical problems.

[0047] As shown in FIG2 , a communication method is provided in an embodiment of the present disclosure, and the communication method includes S101 and S102 .

[0048] In S101 , the energy supply device sends an energy signal to the energy charging device; correspondingly, the energy charging device receives the energy signal sent by the energy supply device.

[0049] The energy signal can be a narrowband signal or a broadband signal.

[0050] In some embodiments, the energy supply device may send the energy signal periodically or aperiodically, which is not limited.

[0051] In S102 , the energy charging device sends measurement information of the energy signal to the energy supply device; correspondingly, the energy supply device receives the measurement information of the energy signal sent by the energy charging device.

[0052] In some embodiments, after receiving the energy signal, the charging device may obtain measurement information of the energy signal by measuring the energy signal.

[0053] The energy signal measurement information includes a measurement value of the energy signal. Exemplarily, the measurement value of the energy signal includes at least one of the following: received signal strength indicator, received signal power, received signal quality, energy collection efficiency, energy collection status, maximum energy value, and minimum energy value.

[0054] Some of the above-mentioned measurement values, such as received signal power, received signal quality, and energy collection efficiency, can be reported in the form of quantized values, levels, maximum values, minimum values, or average values.

[0055] The energy harvesting status can be used to indicate whether energy has been harvested. For example, a first energy harvesting status indicates that the charging device has harvested energy, or that the energy-related parameters (such as power, efficiency, and amplitude) collected by the charging device are greater than a threshold value. A second energy harvesting status indicates that the charging device has not harvested energy, or that the energy-related parameters collected by the charging device are less than or equal to a threshold value.

[0056] In some embodiments, the measurement information may also include an energy signal index corresponding to the measured value. Exemplarily, the energy signal index includes at least one of the following: a time domain resource index, a frequency domain resource index, and a port index. It should be understood that the energy signal index is used to identify the energy signal. In some scenarios (e.g., during beam training), the energy signal index may also serve as the index of the beam that transmits the energy signal.

[0057] In some embodiments, during beam training, the measurement information may also include at least one of the following: the indexes of the best m beams and the indexes of the worst k beams, where m and k are both positive integers. For a charging device, the best m beams may be the m beams with the best channel quality among the multiple beams configured for the charging device. The worst k beams may be the k beams with the worst channel quality among the multiple beams configured for the charging device. The channel quality of a beam can be determined by measuring the energy signal transmitted by that beam.

[0058] It should be understood that, when the measurement information includes the indexes of the optimal m beams, the energy supply device may select a beam from the optimal m beams for communicating or transmitting energy with the charging device.

[0059] In the case where the measurement information includes the indexes of the worst k beams, the energy supply device may select a beam for communicating or transmitting energy with the charging device from beams other than the worst k beams.

[0060] In the disclosed embodiments, the energy signal measurement value in the energy signal measurement information can reflect information about the channel between the energy supply device and the charging device. For example, the received signal strength of the energy signal can indirectly reflect the quality of the channel. Therefore, by sending the energy signal measurement information to the energy supply device, the charging device can obtain information about the channel between the energy supply device and the charging device, thereby achieving channel measurement between the energy supply device and the charging device.

[0061] Compared to traditional reference signal-based channel measurement methods, the energy signal-based channel measurement method in the disclosed embodiments does not require the energy supply device to send additional reference signals, thus saving transmission resource overhead. Furthermore, the energy signal-based channel measurement method in the disclosed embodiments places fewer hardware restrictions on the charging device. Regardless of whether the charging device has or has enabled signal detection, the charging device can measure the energy signal and provide feedback of the energy signal measurement information to the energy supply device to achieve channel measurement.

[0062] In some embodiments, the feedback mode of the measurement information may be a periodic feedback mode or an aperiodic feedback mode. It should be understood that the charging device may determine the feedback mode of the measurement information based on pre-configuration or control signaling sent by the energy supply device.

[0063] In some embodiments, based on the periodic transmission of the energy signal and the periodic feedback of the measurement information, the energy signal transmission period T1 and the measurement information feedback period T2 may be the same or different, without limitation. The time units of the transmission period T1 and the feedback period T2 may be any one of microseconds, milliseconds, frames, subframes, half frames, time slots, and symbols.

[0064] For example, assuming that the energy signal transmission period T1 and the measurement information feedback period T2 are the same, as shown in Figure 3, after receiving the energy signal, the charging device can send the energy signal measurement information to the energy supply device after a preset time T3. The charging device then repeats the process of receiving the energy signal and feeding back the measurement information. It should be understood that the preset time T3 can be preconfigured or configured by the energy supply device for the charging device. The time unit of the preset time T3 can be any one of microseconds, milliseconds, frames, subframes, half-frames, time slots, and symbols.

[0065] In some embodiments, when the measurement information is fed back in an aperiodic manner, the energy supply device detects in real time whether the charging device feeds back the measurement information.

[0066] In some embodiments, when the measurement information is fed back in an aperiodic manner, the charging device may feed back the measurement information of the energy signal once after receiving the energy signal multiple times.

[0067] The measurement information is fed back in an aperiodic manner. The following examples 1 to 5 illustrate how the charging device feeds back the measurement information.

[0068] In example one, the charging device may send measurement information to the energy supply device when the measured value of the energy signal is less than the first threshold. In this way, the energy supply device may learn that the measured value of the energy signal is less than the first threshold, thereby increasing the charging power (that is, the transmission power of the energy signal) or re-performing the beam training process with the charging device. The first threshold may be a preset value or calculated based on the best measured value during the beam training process. For example, the first threshold may satisfy the following relationship: η = αP, where η represents the first threshold, P represents the best measured value during the beam training process, and 0<α<1.

[0069] In a second example, the charging device may send measurement information to the energy supply device when the measured value of the energy signal is greater than a second threshold. In this way, the energy supply device may learn that the measured value of the energy signal is greater than the second threshold, thereby reducing the charging power.

[0070] In a third example, the charging device may send measurement information to the energy supply device when the power level of the charging device is greater than a third threshold.

[0071] In other words, when the battery level of the charging device is low, the charging device can enter a dormant state, only receiving energy signals but not transmitting signals (i.e., not feeding back measurement information). After the charging device has collected sufficient power, it sends measurement information to the energy supply device. After receiving this measurement information, the energy supply device can determine that the battery level of the charging device is greater than the third threshold and can therefore decide to stop supplying energy to the charging device.

[0072] In a fourth example, a charging device may send measurement information to an energy supply device while sending a charging request message to the energy supply device. The charging request message is used to request the energy supply device to supply energy to the charging device. The charging request message may include measurement information of the energy signal; alternatively, the charging request message and measurement information may be two independent pieces of signaling.

[0073] In Example 5, the charging device may send measurement information to the energy supply device while sending a charging change request message to the energy supply device. The charging change request message may include any of the following: an instruction to stop charging, an instruction to increase the charging power, or an instruction to decrease the charging power. The charging change request message may include measurement information of the energy signal; alternatively, the charging change request message and the measurement information may be two independent pieces of signaling.

[0074] In some embodiments, the energy supply device sends measurement information configuration information to the charging device; correspondingly, the charging device receives the measurement information configuration information sent by the energy supply device. The measurement information configuration information is used to configure at least one of the feedback method of the measurement information, the content of the measurement information, and the transmission resource of the measurement information.

[0075] For example, the configuration information of the measurement information may configure the measurement information to adopt a periodic feedback mode, and the measurement value in the measurement information includes the received signal power.

[0076] For another example, the configuration information of the measurement information may configure the measurement information to adopt a non-periodic feedback mode, and the measurement values ​​in the measurement information include energy collection efficiency and energy collection status.

[0077] On the basis of the periodic feedback mode of the measurement information, the configuration information of the measurement information may also be used to configure the feedback period of the measurement information.

[0078] On the basis of adopting the aperiodic feedback mode of the measurement information, the configuration information of the measurement information can also be used to configure the feedback condition of the measurement information. Exemplarily, the feedback condition of the measurement information includes any one of the following conditions 1 to 5.

[0079] Condition 1: The measured value of the energy signal is less than a first threshold.

[0080] Condition 2: The measured value of the energy signal is greater than the second threshold.

[0081] Condition 3: The power level of the charging device is greater than a third threshold.

[0082] Condition 4: The charging device sends a charging request message to the energy supply device.

[0083] Condition 5: The charging device sends a charging change request message to the energy supply device.

[0084] In some embodiments, the charging device and the energy supply device can determine the optimal beam through a beam training process. The optimal beam can include an optimal transmit beam and an optimal receive beam aligned with the optimal transmit beam. During the energy transmission phase, the energy supply device transmits the energy signal through the optimal transmit beam, and the charging device receives the energy signal through the optimal receive beam. If the measured value of the energy signal is less than a threshold value, the beam training process can be repeated between the charging device and the energy supply device. The beam training process includes transmit beam training and can further include receive beam training.

[0085] In some embodiments, a beam training process based on the energy signal can be performed between the energy supply device and the charging device. Alternatively, if the charging device has a signal detection function, a beam training process based on the first measurement reference signal can also be performed between the energy supply device and the charging device.

[0086] The following is an introduction to the beam training process based on energy signals.

[0087] (1) Send beam training

[0088] The above S101 can be implemented as follows: the energy supply device transmits energy signals to the charging device using M transmission beams; correspondingly, the charging device receives the energy signals transmitted by the energy supply device using the M transmission beams, where M is an integer greater than 1.

[0089] It should be noted that the energy signals sent using different transmit beams may occupy the same frequency domain resources, but occupy different time domain resources (ie, different transmission times).

[0090] The above S102 can be implemented as follows: the charging device sends measurement information corresponding to each of the M transmission beams to the power supply device; correspondingly, the power supply device receives measurement information of energy signals corresponding to each of the M transmission beams sent by the charging device.

[0091] In this way, the energy supply device can determine the transmit beam with the best measurement value as the optimal transmit beam based on the measurement information corresponding to each of the M transmit beams.

[0092] As an example, with reference to Figure 4 , the energy supply device is configured with transmit beams 1 to 4. The energy supply device uses different transmit beams to transmit energy signals at different times. For example, transmit beam 1 transmits energy signal 1, transmit beam 2 transmits energy signal 2, transmit beam 3 transmits energy signal 4, and transmit beam 4 transmits energy signal 4. The energy supply device can measure the received signal strength corresponding to different transmit beams. As can be seen from Figure 4 , since transmit beam 2 has the highest received signal strength, transmit beam 2 can be determined to be the optimal transmit beam.

[0093] In some embodiments, for each transmit beam, the charging device may receive the energy signal from a transmit beam and then, after a preset time interval, send measurement information of the energy signal corresponding to that transmit beam to the power supply device. In other words, the measurement information corresponding to each of the M transmit beams may be reported to the power supply device in a time-sharing manner.

[0094] In some embodiments, after receiving the energy signals sent by the M transmit beams, the charging device may send the measurement information corresponding to the transmit beam to the energy supply device after a preset time. In other words, the measurement information corresponding to each of the M transmit beams may be reported to the energy supply device simultaneously.

[0095] In some embodiments, during the beam training process, the charging device may also report only one piece of measurement information, where the measurement information includes the indexes of the best m beams and / or the indexes of the worst k beams.

[0096] (2) Receive beam training

[0097] If the charging device is configured with N receiving beams, the power supply device sends N energy signals to the charging device through each of the M transmitting beams. For the same transmitting beam, the charging device uses different receiving beams in turn to receive the energy signals sent by the transmitting beam.

[0098] In this way, for each transmit beam, the charging device can obtain the measurement values ​​corresponding to each of the N receive beams. Based on the measurement values ​​corresponding to each of the N receive beams, the charging device selects the receive beam corresponding to the best measurement value as the receive beam aligned with the transmit beam. The measurement value corresponding to the receive beam is the measurement value of the energy signal received by the receive beam.

[0099] In some embodiments, for each transmit beam, the measurement information corresponding to that transmit beam includes the measured value of the energy signal received by the receive beam aligned with that transmit beam. Thus, as shown in Figure 5, the charging device can report the measurement information corresponding to the transmit beam once after the energy supply device has sent energy signals using the same transmit beam N times. This eliminates the need for the charging device to provide measurement information for each energy signal, saving signaling overhead.

[0100] The beam training process is described below with reference to Figure 6. As shown in Figure 6, the energy supply device is configured with transmit beams 1 to 4, and the charging device is configured with receive beams 1 and 2. The energy supply device sends energy signal 1 via transmit beam 1, and the charging device receives energy signal 1 via receive beam 1. The energy supply device sends energy signal 2 via transmit beam 1, and the charging device receives energy signal 2 via receive beam 2. In this way, based on the measurement values ​​of receive beam 1 and receive beam 2, the charging device can determine the receive beam aligned with transmit beam 1 from receive beam 1 and receive beam 2, and feedback measurement information 1 corresponding to transmit beam 1 to the energy supply device. This measurement information 1 includes the measurement values ​​corresponding to the receive beam aligned with transmit beam 1.

[0101] Continuing with Figure 6, the energy supply device transmits energy signal 3 via transmit beam 2, and the charging device receives energy signal 3 via receive beam 1. The energy supply device transmits energy signal 4 via transmit beam 2, and the charging device receives energy signal 4 via receive beam 2. In this way, based on the measurement values ​​of receive beam 1 and receive beam 2, the charging device can determine the receive beam aligned with transmit beam 2 from receive beam 1 and receive beam 2, and feed back measurement information 2 corresponding to transmit beam 2 to the energy supply device. This measurement information 2 includes the measurement values ​​corresponding to the receive beam aligned with transmit beam 2.

[0102] Similarly, the charging device can determine the receiving beam that each transmitting beam is aligned with, and feed back the measurement information corresponding to each transmitting beam to the power supply device.

[0103] In some embodiments, the charging device can switch between a charging state and a communication state. As shown in FIG7 , there is a switching time t0 between the charging time period and the communication time period of the charging device. It should be understood that the length of the switching time depends on the capabilities of the charging device itself.

[0104] In some embodiments, the charging device can transition between the charging state and the communication state using DRX. Specifically, as shown in Figure 8, during the DRX-on phase, the charging device is in the communication state; during the DRX-off phase, the charging device is in the charging state. It should be understood that by using DRX to transition between the charging state and the communication state, the charging device's charging and communication time periods do not conflict, thus achieving the goal of balancing the charging device's communication and charging needs.

[0105] In some embodiments, during the DRX-on phase, the charging device and the energy supply device may perform channel measurements and / or beam training for communication. During the DRX-off phase, the charging device transitions from the communication state to the charging state, and the energy supply device may use the channel measurement results and / or beam training results to send an energy signal to the charging device.

[0106] In some embodiments, during the DRX on phase, the energy supply device may send a first measurement reference signal to the charging device and receive feedback from the charging device regarding the measurement result of the first measurement reference signal to implement channel measurement and / or beam training. This process is described in detail in the embodiment shown in FIG. 9 below and is not further described here.

[0107] In some embodiments, during the DRX on phase, the energy supply device may receive a second measurement reference signal sent by the charging device to implement channel measurement. This process is described in detail in the embodiment shown in FIG. 14 below and is not described in detail here.

[0108] In some embodiments, during the DRX on phase, the energy supply device may send control signaling to the charging device. Exemplarily, the control signaling may include configuration information of the measurement information, configuration information of the second measurement reference signal, and / or other configuration information (e.g., configuration information for configuring the transmission resources of the energy signal). The control signaling may be downlink control information (DCI), a medium access control-control element (MAC CE), or radio resource control (RRC) signaling, without limitation.

[0109] In some embodiments, during the DRX off phase, the charging device may obtain measurement information of the energy signal based on the measurement of the energy signal, and send the measurement information to the energy supply device.

[0110] In some embodiments, during the DRX off phase, the charging device may obtain energy signal measurement information based on the energy signal measurement, but the charging device does not report the measurement information. After switching to the DRX on phase, the charging device sends the measurement information to the energy supply device.

[0111] In some embodiments, the energy supply device may send one or more DRX configurations to the charging device; correspondingly, the charging device receives the one or more DRX configurations sent by the energy supply device.

[0112] In the case where the energy supply device sends multiple DRX configurations, the charging device may inform the energy supply device of the DRX configuration that the charging device desires to use.

[0113] The DRX configuration may include at least one of the following parameters: DRX on-duration (drx-onDurationTimer), DRX on-time delay (drx-SlotOffset), DRX long cycle and on-time delay (drx-LongCycleStartOffset), DRX activation time (drx-InactivityTimer), and short DRX cycle (drx-ShortCycleTime). The meaning of the parameters in the DRX configuration can be referred to in related technologies and will not be detailed here.

[0114] It should be understood that, compared to ordinary terminals (that is, terminals that only communicate), the DRX configuration of charging devices needs to additionally consider the switching time between the charging state and the communication state. For charging devices, the duration of the DRX on phase is determined according to the duration that the charging device is in the communication state, and the duration of the DRX off phase is determined according to the duration that the charging device is in the charging state and the switching duration. For example, as shown in Figure 8, within a DRX cycle, the duration of the DRX on phase is the same as that of a device that only communicates, and the DRX off phase requires two additional switching times t0. Therefore, each DRX cycle needs to be extended by 2*t0. Assuming that the DRX cycle for the communication device is T, then for the charging device, the configured DRX cycle is T+2t0.

[0115] As shown in FIG9 , the embodiment of the present disclosure further provides a communication method, which includes the following S201 to S202 .

[0116] In S201 , the energy supply device sends a first measurement reference signal to the energy charging device; correspondingly, the energy charging device receives the first measurement reference signal sent by the energy supply device.

[0117] As an implementation manner, when the charging device is in the DRX on stage, or in the communication state, the energy supply device sends a first measurement reference signal to the charging device; accordingly, the charging device receives the first measurement reference signal sent by the energy supply device.

[0118] The first measurement reference signal includes any one of the following: a channel state information-reference signal (CSI-RS), a demodulation reference signal (DMRS), and a synchronization signal / physical broadcast channel block (SS / PBCH).

[0119] In some embodiments, the first measurement reference signal may also be other types of signals, such as a broadband pulse signal, a single-frequency sinusoidal wave signal, a square wave signal, a triangle wave signal, a sawtooth wave signal, or an orthogonal frequency division multiplexing (OFDM) signal.

[0120] In some embodiments, the first measurement reference signal may be sent periodically or aperiodically. The time unit of the transmission period of the first measurement reference signal may be a symbol, a time slot, a frame, a subframe, etc., which is not limited thereto.

[0121] In some embodiments, as shown in Figure 10, the first measurement reference signal may occupy only one subcarrier in the frequency band. In this case, the first measurement reference signal is a narrowband signal. Each square in Figure 10 represents a resource element (RE), which includes one symbol in the time domain and one subcarrier in the frequency domain.

[0122] In some embodiments, the first measurement reference signal is transmitted using a single port associated with multiple beams. Therefore, the energy supply device can transmit the first measurement reference signal in a time-division manner. That is, the energy supply device can transmit the first measurement reference signal using different beams at different transmission times on the same port to perform beam training.

[0123] In some embodiments, as shown in Figure 11, the first measurement reference signal can occupy all subcarriers in the frequency band. For example, if the physical resource blocks (PRBs) of the frequency band allocated for energy transmission are numbered 1 to 50, the first measurement reference signal is inserted into each subcarrier of these 50 resource blocks. For the energy supply device, the first measurement reference signals on all subcarriers within the same symbol time are transmitted using the same beam; while the first measurement reference signals at different symbol times are transmitted using different beams.

[0124] In some embodiments, the first measurement reference signal may occupy P subcarriers in the frequency band, where P is less than the total number of subcarriers in the frequency band used for energy transmission, and P is an integer greater than 1.

[0125] As an example, as shown in FIG12 , the first measurement reference signal can be inserted into P subcarriers at equal intervals on the frequency band. The subcarrier number p of the subcarrier into which the first measurement reference signal is inserted can be calculated using formula (1): p = m + Kn (1)

[0126] In formula (1), K is a positive integer representing the spacing between two adjacent subcarriers inserted with the first sounding reference signal. m represents the spacing between the first subcarrier inserted with the first sounding reference signal and the first subcarrier in the frequency band, where m is an integer satisfying 0 ≤ m ≤ K. n is a non-negative integer.

[0127] As another example, as shown in FIG13 , the first measurement reference signal may occupy P consecutive subcarriers in the frequency band.

[0128] The aforementioned frequency bands may be used for energy transmission, without limitation. Frequency bands used for energy transmission may be preconfigured or configured by the energy supply device for the charging device. For multiple charging devices served by the same energy supply device, all charging devices may be configured with the same frequency band; alternatively, different devices may be independently configured with different frequency bands.

[0129] In some embodiments, the first measurement reference signal can be sent using multiple ports, each of which is associated with a beam. This means that different beams can be carried on different ports to transmit the first measurement reference signal. Furthermore, the same port can transmit the first measurement reference signal multiple times consecutively to assist the charging device in beam training at the receiving end.

[0130] In some embodiments, the first measurement reference signal includes at least one of the following: a first measurement reference signal of a first type, a first measurement reference signal of a second type, and a first measurement reference signal of a third type. The first measurement reference signal of the first type is used for energy transmission, the second type of first measurement reference signal is used for communication, and the third type of first measurement reference signal is used for both energy transmission and communication. Different types of first measurement reference signals correspond to different ports, time-frequency resources, and / or signal types.

[0131] As an example, the time-frequency resources of the first measurement reference signal used for energy transmission are different from the time-frequency resources of the first measurement reference signal used for communication. In this way, the charging device can identify whether the received first measurement reference signal is the first measurement reference signal used for energy transmission based on the time-frequency resources of the first measurement reference signal.

[0132] As another example, the port of the first measurement reference signal used for energy transmission is different from the port of the first measurement reference signal used for communication. In this way, the charging device can identify whether the received first measurement reference signal is the first measurement reference signal used for energy transmission based on the port of the received first measurement reference signal.

[0133] In S202 , the energy charging device sends a measurement result of a first measurement reference signal to the energy supply device; correspondingly, the energy supply device receives the measurement result of the first measurement reference signal sent by the energy charging device.

[0134] In some embodiments, the charging device measures the first measurement reference signal to obtain a measurement result of the first measurement reference signal. The measurement result may also be channel state information (CSI).

[0135] In some embodiments, the measurement results may include parameters for indicating the beamforming vector used by the energy supply device to transmit the energy signal, such as a precoding matrix indicator (PMI), a channel quality indicator (CQI), a layer indicator (LI), and a rank indicator (RI). For example, after the charging device estimates the channel using the received first measurement reference signal, it calculates the optimal precoding vector and quantizes the optimal precoding vector using a codebook to determine the PMI.

[0136] In some embodiments, the measurement results may also include relevant parameters used to assist beam training, such as Layer 1-Reference Signal Receiving Power (L1-RSRP) and Synchronization Signal / Physical Broadcast Channel Block Resource Indicator (SSBRI). For example, during beam training, the power supply device may use different beams at different times to send the first measurement reference signal; accordingly, the power supply device may measure the first measurement reference signals of different beams to determine the L1-RSRP corresponding to the different beams.

[0137] In some embodiments, the measurement result may further include at least one of the following: a time index of the first measurement reference signal, a received signal strength indicator, a resource index of the first measurement reference signal, a port index of the first measurement reference signal, and a transmission mode. The port index may also be referred to as a port number, which is not limited thereto.

[0138] In some embodiments, the feedback method for the measurement result of the first measurement reference signal may be a periodic feedback method or an aperiodic feedback method. When the measurement result of the first measurement reference signal is fed back aperiodically, the feedback conditions for the measurement result of the first measurement reference signal may refer to the feedback method for the measurement information of the energy signal described above, and are not further described here.

[0139] In some embodiments, taking the energy supply device as a base station and the charging device as a terminal as an example, the measurement result of the first measurement reference signal can be carried on a physical uplink shared channel (PUSCH) or a physical uplink control channel (PUCCH) for transmission.

[0140] In some embodiments, taking the case where both the energy supply device and the charging device are terminals, the measurement result of the first measurement reference signal can be carried on a physical sidelink shared channel (PSSCH) or a physical sidelink control channel (PSCCH) for transmission.

[0141] In some embodiments, the energy supply device may determine an energy signal transmission configuration based on a measurement result of the first measurement reference signal; during the DRX off phase of the energy charging device, the energy supply device transmits the energy signal to the energy charging device based on the energy signal transmission configuration. The transmission configuration includes, but is not limited to, at least one of the following: precoding weight, transmit power, transmit period, and transmission resource.

[0142] In the disclosed embodiment, the energy supply device transmits a first measurement reference signal to the charging device and receives feedback from the charging device regarding the measurement result of the first measurement reference signal. Because this measurement result reflects the channel state information between the energy supply device and the charging device, the energy supply device can provide stable and efficient energy supply services to the charging device based on this measurement result.

[0143] As shown in FIG14 , an embodiment of the present disclosure further provides a communication method, which includes the following S301 and S302 .

[0144] In S301 , the energy supply device sends configuration information of a second measurement reference signal to the charging device; correspondingly, the charging device receives the configuration information of the second measurement reference signal sent by the energy supply device.

[0145] The configuration information of the second measurement reference signal is used to configure parameters related to the second measurement reference signal. For example, the parameters related to the second measurement reference signal include at least one of the following: a transmission port, a frequency, a bandwidth, a waveform, a period, and a transmission mode. The transmission mode of the second measurement reference signal can be a periodic transmission mode or an aperiodic transmission mode.

[0146] In S302 , the charging device sends the second measurement reference signal to the energy supply device according to the configuration information of the second measurement reference signal; correspondingly, the energy supply device receives the second measurement reference signal sent by the charging device according to the configuration information of the second measurement reference signal.

[0147] As an implementation manner, when the charging device is in the DRX on stage, or in the communication state, the charging device sends a second measurement reference signal to the energy supply device; accordingly, the energy supply device receives the second measurement reference signal sent by the charging device.

[0148] In some embodiments, the second measurement reference signal may be a channel sounding reference signal (SRS), or other types of signals, such as a single-frequency sinusoidal signal, a wideband pulse signal, an OFDM signal, etc.

[0149] In some embodiments, when the second measurement reference signal is transmitted periodically, the transmission period of the second measurement reference signal may be one or more fixed values. Different types of second measurement reference signals may correspond to different transmission periods. In this way, the energy supply device can determine the transmission period of the second measurement reference signal based on the type of the received second measurement reference signal.

[0150] In some embodiments, when the second measurement reference signal is transmitted aperiodically, the charging device may transmit the second measurement reference signal when a preset condition is satisfied. For example, the preset condition may include a measurement value (e.g., average power) of the received energy signal being less than a preset threshold.

[0151] In some embodiments, the second measurement reference signal may occupy one subcarrier, P subcarriers, or all subcarriers in the frequency band. P is less than the total number of subcarriers in the frequency band used for energy transmission, and P is an integer greater than 1. When the second measurement reference signal occupies P subcarriers, the second measurement reference signal occupies non-contiguous P subcarriers. For example, the subcarriers occupied by the second measurement reference signal may be evenly spaced across the frequency band; alternatively, the second measurement reference signal occupies P contiguous subcarriers.

[0152] In some embodiments, the second measurement reference signal includes at least one of the following: a first type of second measurement reference signal, a second type of second measurement reference signal, and a third type of second measurement reference signal. The first type of second measurement reference signal is used for energy transmission, the second type of second measurement reference signal is used for communication, and the third type of second measurement reference signal is used for energy transmission and communication. Different types of second measurement reference signals correspond to different ports, time-frequency resources, and / or signal types. Therefore, the energy supply device can identify the type of the received second measurement reference signal based on the port, time-frequency resource, and / or signal type of the received second measurement reference signal.

[0153] In some embodiments, the energy supply device may configure ports and / or time-frequency resources of different types of second measurement reference signals by sending control signaling to the charging device.

[0154] In some embodiments, the energy supply device measures the second measurement reference signal to obtain a measurement result of the second measurement reference signal. The energy supply device may determine the energy signal transmission configuration based on the measurement result of the second measurement reference signal; in the DRX off phase of the charging device, the energy supply device sends the energy signal to the charging device according to the energy signal transmission configuration. The measurement result of the second measurement reference signal may reflect the channel state information of the channel between the energy supply device and the charging device. The measurement result of the second measurement reference signal may include at least one of the following: received signal quality, received signal strength, received signal power, precoding matrix, and channel quality.

[0155] In the disclosed embodiment, the energy supply device receives the second measurement reference signal sent by the charging device to obtain channel state information of the channel between the energy supply device and the charging device. In this way, the energy supply device can provide stable and efficient energy supply services to the charging device based on this channel state information.
