[0042] The communication method provided by the embodiment of the present disclosure can be applied to systems of various communication formats.

In addition, the communication method provided by the embodiment of the present disclosure can also be applied to future-oriented communication systems, etc.
[0043] like Figure 1 As shown, a wireless power supply system provided in an embodiment of the present disclosure is provided. The wireless power supply system includes a power supply device 10 and a charging device 20.
[0044] 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.
[0045] 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.
[0046] In the disclosed embodiment, 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.
[0047] In some embodiments, the energy supply device 10 can send an energy signal through a directional beam to make the radiation energy of the energy signal more concentrated, thereby increasing the coverage distance of the energy signal. In the case where the energy signal is sent through a directional beam, beam training can be performed between the energy supply device 10 and the charging device 20 to determine the optimal beam. The beam training may 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).
[0048] In some embodiments, the energy charging device 20 may also have a communication function. Based on this, the energy supply device 10 and the energy charging device 20 may communicate with each other. As an example, the energy charging device 20 may send energy signal-related demand information to the energy supply device 10. As another example, the energy supply device 10 may send energy signal-related information (such as the cycle of the energy signal, etc.) to the energy charging device 20.
[0049] In some embodiments, on the basis that the charging device 20 has a communication function, the charging device 20 may enable discontinuous reception (DRX) to save energy consumption.
[0050] In the embodiment of the present disclosure, the product form of the energy supply device 10 and the charging device 20 is not limited. As an example, Figure 1 As shown, the energy supply device 10 may be a base station, and the charging device 20 may be a terminal.
[0051] 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 may 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.
[0052] In some embodiments, the terminal may be a device with wireless transceiver function. The terminal may 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 self-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 may 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 device, UE agent or UE device, etc., which are not limited in the embodiments of the present disclosure.
[0053] 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. It is known to those skilled in the art 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 also applicable to similar technical problems.
[0054] like Figure 2 As shown, a communication method provided by an embodiment of the present disclosure includes:
[0055] 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.
[0056] The energy signal may be a narrowband signal or a broadband signal.
[0057] In some embodiments, the energy supply device may send energy signals periodically or aperiodically, without limitation.
[0058] 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.
[0059] In some embodiments, after receiving the energy signal, the charging device may obtain measurement information of the energy signal by measuring the energy signal.
[0060] The measurement information of the energy signal includes the measurement value of the energy signal. Exemplarily, the measurement value of the energy signal includes at least one of the following: received signal strength indication, received signal power, received signal quality, energy collection efficiency, energy collection status, maximum energy value, and minimum energy value.
[0061] 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.
[0062] The energy collection state can be used to indicate whether energy is collected. For example, the energy collection state is the first state, indicating that the charging device collects energy, or the energy-related parameters (such as power, efficiency, amplitude) collected by the charging device are greater than the threshold value. The energy collection state is the second state, indicating that the charging device does not collect energy, or the energy-related parameters collected by the charging device are less than or equal to the threshold value.
[0063] In some embodiments, the measurement information may also include an energy signal index corresponding to the measurement 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 be used as an index of the beam that sends the energy signal.
[0064] In some embodiments, during the beam training process, the measurement information may also include at least one of the following: the index of the best m beams, the index of the worst k beams, where m and k are both positive integers. Among them, for the charging device, the best m beams may be the m beams with the best channel quality among the multiple beams configured for the energy supply device. The worst k beams may be the k beams with the worst channel quality among the multiple beams configured for the energy supply device. The channel quality of a beam can be determined by the measured value of the energy signal transmitted by the beam.
[0065] 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.
[0066] 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 other beams except the worst k beams.
[0067] In the disclosed embodiment, since the measured value of the energy signal in the measurement information of the energy signal can reflect the information of 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 measurement information of the energy signal to the energy supply device, the energy charging device can enable the energy supply device to obtain the information of the channel between the energy supply device and the charging device, that is, to achieve the channel measurement between the energy supply device and the charging device.
[0068] Compared with the traditional reference signal-based channel measurement method, the energy signal-based channel measurement method in the embodiment of the present disclosure does not require the energy supply device to send additional reference signals to save transmission resource overhead. In addition, the energy signal-based channel measurement method in the embodiment of the present disclosure has fewer hardware restrictions on the charging device. Regardless of whether the charging device has or turns on the signal detection function, the charging device can measure the energy signal and feed back the energy signal measurement information to the energy supply device to achieve channel measurement.
[0069] 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 a pre-configuration or a control signaling sent by the energy supply device.
[0070] In some embodiments, based on the energy signal being sent periodically and the measurement information being fed back periodically, the energy signal sending period T1 and the measurement information feedback period T2 may be the same or different, and there is no limitation on this. The time unit of the sending period T1 and the feedback period T2 may be any one of microseconds, milliseconds, frames, subframes, half frames, time slots, and symbols.
[0071] For example, the energy signal transmission period T1 and the measurement information feedback period T2 are the same as each other. Figure 3 As shown, after receiving the energy signal, the charging device can send the measurement information of the energy signal to the energy supply device after a preset time T3; then, the charging device repeats the action of receiving the energy signal and feeding back the measurement information. It should be understood that the preset time T3 can be preconfigured, or the energy supply device can configure it 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.
[0072] In some embodiments, when the measurement information is fed back in a non-periodic manner, the energy supply device detects in real time whether the charging device feeds back the measurement information.
[0073] In some embodiments, when the measurement information is fed back in a non-periodic manner, the charging device may feed back the measurement information of the energy signal once after receiving the energy signal multiple times.
[0074] The measurement information is fed back in an aperiodic manner. The following is an exemplary description of the charging device feeding back the measurement information.
[0075] Example 1: The charging device can 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 can 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 can be a preset value or calculated based on the best measured value during the beam training process. For example, the first threshold can 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.
[0076] Example 2: When the measured value of the energy signal is greater than the second threshold, the charging device may send measurement information to the energy supply device. 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.
[0077] Example three: The charging device may send measurement information to the energy supply device when the power level of the charging device is greater than the third threshold.
[0078] That is to say, when the power of the charging device is low, the charging device can enter a dormant state, only receiving energy signals but not transmitting signals (that is, not feeding back measurement information). After the charging device collects enough power, the charging device sends measurement information to the energy supply device. After receiving the measurement information, the energy supply device can learn that the power of the charging device is greater than the third threshold, so it can decide to stop supplying energy to the charging device.
[0079] Example 4: The charging device may send measurement information to the energy supply device when 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; or, the charging request message and the measurement information may be two independent signalings.
[0080] Example 5: The charging device may send measurement information to the energy supply device when sending a charging change request message to the energy supply device. The charging change request message may include any one of the following: an instruction to stop charging, an instruction to increase the charging power, and an instruction to reduce the charging power. The charging change request message may include measurement information of the energy signal; or, the charging change request message and the measurement information may be two independent signals.
[0081] In some embodiments, the energy supply device sends configuration information of the measurement information to the charging device; correspondingly, the charging device receives the configuration information of the measurement information sent by the energy supply device, wherein the configuration information of the measurement information is used to configure at least one of the feedback mode of the measurement information, the content of the measurement information, and the transmission resource of the measurement information.
[0082] 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.
[0083] 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.
[0084] On the basis that the measurement information is fed back in a periodic manner, the configuration information of the measurement information may also be used to configure a feedback period of the measurement information.
[0085] On the basis of the measurement information adopting the aperiodic feedback mode, 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:
[0086] Condition 1: The measured value of the energy signal is less than the first threshold;
[0087] Condition 2: the measured value of the energy signal is greater than the second threshold;
[0088] Condition 3: The power of the charging device is greater than the third threshold;
[0089] Condition 4: The charging device sends a charging request message to the supply device;
[0090] Condition 5: The charging device sends a charging change request message to the supply device.
[0091] In some embodiments, the optimal beam can be determined between the charging device and the energy supply device through a beam training process. The optimal beam may 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 sends an energy signal through the optimal transmit beam, and the energy supply device receives the energy signal through the optimal receive beam. When the measured value of the energy signal is less than the 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 may further include receive beam training.
[0092] In some embodiments, a beam training process based on an energy signal may be performed between the energy supply device and the charging device. Alternatively, on the premise that the charging device has a signal detection function, a beam training process based on a first measurement reference signal may also be performed between the energy supply device and the charging device.
[0093] The following is an introduction to the beam training process based on energy signals.
[0094] (1) Send beam training
[0095] The above step S101 can be implemented as follows: the energy supply device sends energy signals to the energy charging device using M transmission beams respectively; correspondingly, the energy charging device receives the energy signals sent by the energy supply device using M transmission beams respectively. M is an integer greater than 1.
[0096] It should be noted that the energy signals sent using different transmission beams may occupy the same frequency domain resources, but occupy different time domain resources (ie, different transmission times).
[0097] The above step 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.
[0098] 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.
[0099] Combination Figure 4 For example, the energy supply device is configured with transmission beams 1 to 4. The energy supply device uses different transmission beams to send energy signals at different times. For example, transmission beam 1 sends energy signal 1, transmission beam 2 sends energy signal 2, transmission beam 3 sends energy signal 4, and transmission beam 4 sends energy signal 4. The charging device can measure the received signal strength corresponding to different transmission beams. Figure 4 It can be seen that since the received signal strength corresponding to transmit beam 2 is the largest, it can be determined that transmit beam 2 is the optimal transmit beam.
[0100] In some embodiments, for each transmission beam, after receiving the energy signal sent by a transmission beam, the charging device can send the measurement information of the energy signal corresponding to the transmission beam to the energy supply device after a preset time. That is, the measurement information corresponding to each of the M transmission beams can be reported to the energy supply device in a time-sharing manner.
[0101] In some embodiments, after receiving the energy signals sent by the M transmission beams, the charging device may send the measurement information corresponding to the transmission beam to the energy supply device after a preset time. That is, the measurement information corresponding to each of the M transmission beams may be reported to the energy supply device at the same time.
[0102] In some embodiments, during the beam training process, the charging device may also report only one measurement information, where the measurement information includes the indexes of the best m beams and / or the indexes of the worst k beams.
[0103] (2) Receive beam training
[0104] When the charging device is configured with N receiving beams, the energy 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 signal sent by the transmitting beam.
[0105] In this way, for each transmit beam, the charging device can obtain the measurement values corresponding to each of the N receive beams, and based on the measurement values corresponding to each of the N receive beams, select 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.
[0106] In some embodiments, for each transmit beam, the measurement information corresponding to the transmit beam includes a measurement value of an energy signal received by a receive beam aligned with the transmit beam. Figure 5 As shown, the charging device can report the measurement information corresponding to the transmission beam once after the energy supply device uses the same transmission beam to send energy signals N times. Based on this, the charging device does not need to feedback measurement information for each energy signal, which is conducive to saving signaling overhead.
[0107] Combine the following Figure 6 The beam training process is introduced. Figure 6 As shown, 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 through transmit beam 1, and the charging device receives energy signal 1 through receive beam 1. The energy supply device sends energy signal 2 through transmit beam 1, and the charging device receives energy signal 2 through receive beam 2. In this way, the charging device can determine the receive beam aligned with the transmit beam 1 from the receive beam 1 and the receive beam 2 based on the measurement value of the receive beam 1 and the measurement value of the receive beam 2, and feed back measurement information 1 corresponding to the transmit beam 1 to the energy supply device, and the measurement information 1 includes the measurement value corresponding to the receive beam aligned with the transmit beam 1.
[0108] Please continue to refer to Figure 6 , the energy supply device sends energy signal 3 through transmit beam 2, and the charging device receives energy signal 3 through receive beam 1. The energy supply device sends energy signal 4 through transmit beam 2, and the charging device receives energy signal 4 through receive beam 2. In this way, the charging device can determine the receive beam aligned with the transmit beam 2 from the receive beam 1 and the receive beam 2 based on the measurement value of the receive beam 1 and the measurement value of the receive beam 2, and feed back measurement information 2 corresponding to the transmit beam 2 to the energy supply device, and the measurement information 2 includes the measurement value corresponding to the receive beam aligned with the transmit beam 2.
[0109] By analogy, 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.
[0110] In some embodiments, the charging device can switch between a charging state and a communication state. Figure 7 As shown, there is a switching time 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 capability of the charging device itself.
[0111] In some embodiments, the switching of the charging device between the charging state and the communication state can be achieved through DRX. Figure 8 As shown, in the DRX on stage, the charging device is in the communication state; in the DRX off stage, the charging device is in the charging state. It should be understood that the conversion of the charging device between the charging state and the communication state is realized through DRX, so that the charging time period and the communication time period of the charging device do not conflict, so as to achieve the purpose of taking into account the communication needs and charging needs of the charging device.
[0112] In some embodiments, during the DRX on phase, the charging device and the energy supply device may perform channel measurement and / or beam training for communication. During the DRX off phase, the charging device switches from the communication state to the charging state, and the energy supply device may use the channel measurement result and / or beam training result to send an energy signal to the charging device.
[0113] 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 a measurement result of the first measurement reference signal fed back by the charging device to implement channel measurement and / or beam training. The specific description of this process can be found in the following Fig. 9 The illustrated embodiments are not described in detail here.
[0114] 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. Fig.14 The illustrated embodiments are not described in detail here.
[0115] 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), medium access control-control element (MAC CE), or radio resource control (RRC) signaling, without limitation.
[0116] In some embodiments, during the DRX off phase, the energy 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.
[0117] In some embodiments, in the DRX off phase, the energy charging device can obtain the measurement information of the energy signal based on the measurement of the energy signal, but the energy charging device does not report the measurement information. After switching to the DRX on phase, the energy charging device sends the measurement information to the energy supply device.
[0118] In some embodiments, the energy supply device may send one or more DRX configurations to the charging device; correspondingly, the charging device receives one or more DRX configurations sent by the power supply device.
[0119] 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 expects to use.
[0120] The DRX configuration may include at least one of the following parameters: DRX on-duration time (drx-onDurationTimer), DRX on-time delay (drx-SlotOffset), DRX long cycle and on-time delay (drx-LongCycleStartOffset), DRX activation time (drx-InactivityTimer), short DRX cycle (drx-ShortCycleTime). The meaning of the parameters in the DRX configuration can refer to the relevant technology and will not be repeated here.
[0121] It should be understood that, compared with ordinary terminals (i.e., terminals that only communicate), the DRX configuration of charging devices needs to take into account 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 of the charging device in the communication state, and the duration of the DRX off phase is determined according to the duration of the charging device in the charging state and the switching duration. For example, Figure 8 As shown in the figure, in a DRX cycle, the duration of the DRX on phase is the same as that of the device that only performs communication, 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, the configured DRX cycle for the charging device is T+2t0.
[0122] like Fig. 9 As shown, the embodiment of the present disclosure also provides a communication method, which includes the following steps:
[0123] 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.
[0124] As a possible 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; correspondingly, the charging device receives the first measurement reference signal sent by the energy supply device.
[0125] Among them, the first measurement reference signal includes any one of the following: channel state information-reference signal CSI-RS, demodulation reference signal (demodulation reference signal, DMRS), synchronization signal / physical broadcast channel block (synchronization signal / physical broadcast channel block, SS / PBCH).
[0126] In some embodiments, the first measurement reference signal may also be other types of signals, such as a broadband pulse signal, a single-frequency sine wave signal, a square wave signal, a triangle wave signal, a sawtooth wave signal, or an orthogonal frequency division multiplexing (OFDM) signal.
[0127] 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.
[0128] In some embodiments, Fig.10 As shown, 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. Fig.10 Each square in the represents a resource element (RE), and a resource element includes a symbol in the time domain and a subcarrier in the frequency domain.
[0129] In some embodiments, the first measurement reference signal is sent using a port, and the port is associated with multiple beams. Therefore, the energy supply device can send the first measurement reference signal in a time-division manner. That is, the energy supply device can send the first measurement reference signal using different beams at different sending times on the same port to perform beam training.
[0130] In some embodiments, Fig.11 As shown, the first measurement reference signal can occupy all subcarriers in the frequency band. For example, the physical resource block (PRB) number of the frequency band allocated for energy transmission is 1-50, and the first measurement reference signal is inserted into each subcarrier of these 50 resource blocks (Resource Block). For the energy supply device, the first measurement reference signals on all subcarriers in the same symbol time are sent using the same beam; and the first measurement reference signals at different symbol times are sent using different beams.
[0131] 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.
[0132] As an example, Fig.12 As shown, the first measurement reference signal can be inserted into P subcarriers at equal intervals on the frequency band. The sequence number p of the subcarrier into which the first measurement reference signal is inserted can be calculated using formula (1):
[0133] p=m+Kn (1)
[0134] In formula (1), K is a positive integer, which represents the spacing between two adjacent subcarriers into which the first measurement reference signal is inserted. m represents the spacing between the first subcarrier into which the first measurement reference signal is inserted and the first subcarrier in the frequency band, and m is an integer and satisfies 0≤m≤K. n is a non-negative integer.
[0135] As another example, Fig.13 As shown, the first measurement reference signal may occupy P consecutive subcarriers in the frequency band.
[0136] The above frequency band may be a frequency band used for energy transmission, and there is no limitation on this. The frequency band used for energy transmission may be pre-configured 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; or different devices may independently configure different frequency bands.
[0137] In some embodiments, the first measurement reference signal may be sent using multiple ports, each of which is associated with a beam. That is, different beams may be carried on different ports to send the first measurement reference signal. In addition, the same port may send the first measurement reference signal multiple times in succession to assist the charging device in beam training at the receiving end.
[0138] 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; wherein the first measurement reference signal of the first type is used for energy transmission, the first measurement reference signal of the second type is used for communication, and the first measurement reference signal of the third type is used for energy transmission and communication; different types of first measurement reference signals correspond to different ports, time-frequency resources and / or signal types.
[0139] 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 first measurement reference signal is the first measurement reference signal used for energy transmission based on the time-frequency resources of the received first measurement reference signal.
[0140] 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 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.
[0141] 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.
[0142] 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).
[0143] In some embodiments, the measurement result may include parameters of a beamforming vector for indicating the energy supply device to send an 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 best precoding vector and quantizes the best precoding vector using a codebook to determine the PMI.
[0144] In some embodiments, the measurement results may also include relevant parameters for auxiliary 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 the beam training process, the energy supply device may use different beams at different times to send the first measurement reference signal; accordingly, the charging device may measure the first measurement reference signals of different beams to determine the L1-RSRP corresponding to the different beams.
[0145] In some embodiments, the measurement result may also include at least one of the following: a time index of the first measurement reference signal, a received signal strength indication, 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.
[0146] In some embodiments, the feedback method of the measurement result of the first measurement reference signal may be a periodic feedback method or a non-periodic feedback method. In the case where the measurement result of the first measurement reference signal adopts a non-periodic feedback method, the feedback condition of the measurement result of the first measurement reference signal may refer to the feedback method of the measurement information of the energy signal, which is not repeated here.
[0147] 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 (physical uplink share channel, PUSCH) or a physical uplink control channel (physical uplink control channel, PUCCH) for transmission.
[0148] 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.
[0149] In some embodiments, the energy supply device may determine the energy signal transmission configuration according to the measurement result of the first measurement reference signal; in the DRX off phase of the energy charging device, the energy supply device sends the energy signal to the energy charging device according to the energy signal transmission configuration. The transmission configuration includes but is not limited to at least one of the following: precoding weight, transmission power, transmission cycle, and transmission resource.
[0150] In the embodiment of the present disclosure, the energy supply device sends a first measurement reference signal to the charging device, and receives the measurement result of the first measurement reference signal fed back by the charging device. Since the measurement result can reflect the channel state information of the channel between the energy supply device and the charging device, the energy supply device can provide a stable and efficient energy supply service for the charging device based on the measurement result.
[0151] like Fig.14 As shown, the embodiment of the present disclosure also provides a communication method, which includes the following steps:
[0152] 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.
[0153] The configuration information of the second measurement reference signal is used to configure the relevant parameters of the second measurement reference signal. Exemplarily, 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.
[0154] S302: The charging device sends a 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.
[0155] As a possible 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.
[0156] 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 wave signal, a broadband pulse signal, an OFDM signal, and the like.
[0157] In some embodiments, when the second measurement reference signal is sent in a periodic manner, the sending 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 sending periods. In this way, the energy supply device may learn the sending period of the second measurement reference signal based on the type of the received second measurement reference signal.
[0158] In some embodiments, when the second measurement reference signal is sent in an aperiodic manner, the charging device may send the second measurement reference signal when a preset condition is met. Exemplarily, the preset condition may include that the measurement value (eg, average power) of the received energy signal is less than a preset threshold value.
[0159] In some embodiments, the second measurement reference signal may occupy one subcarrier, P subcarriers, or all subcarriers in the frequency band. Wherein, 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. In the case where the second measurement reference signal occupies P subcarriers, the second measurement reference signal occupies non-continuous P subcarriers, for example, the subcarriers occupied by the second measurement reference signal may be equally spaced on the frequency band; or, the second measurement reference signal occupies continuous P subcarriers.
[0160] 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; wherein 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.
[0161] 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.
[0162] In some embodiments, the energy supply device obtains a measurement result of the second measurement reference signal by measuring the second measurement reference signal. The energy supply device may determine the sending configuration of the energy signal 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 sending configuration of the energy signal. Among them, 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, channel quality.
[0163] In the embodiment of the present disclosure, the energy supply device can obtain the channel state information of the channel between the energy supply device and the energy charging device by receiving the second measurement reference signal sent by the energy charging device. In this way, the energy supply device can provide a stable and efficient energy supply service for the energy charging device based on the channel state information.
