DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be described in more detail below with reference to the drawings and examples. The specific examples described herein are only used to interpret the present application, and are not intended to limit the present application.

[0011] Although the schematic diagram of the device has been divided into functional modules and a logical order has been shown in the flowchart, in some cases the division of modules in the device may differ, or the steps shown or described may be performed in a different order than in the flowchart. The terms "first", "second", etc. in the specification, claims, and above drawings are used to distinguish between similar objects, and are not necessarily intended to describe a particular order or sequence.

[0012] In the description of the embodiments of the present application, unless otherwise clearly limited, terms such as installation, mounting, connection, etc. should be understood in a broad sense, and those skilled in the art may reasonably determine the specific meaning of the above words in the embodiments of the present application by referring to the specific content of the technical solution. In the embodiments of the present application, terms such as "further," "exemplary," or "optionally" are used to represent examples, illustrations, or explanations, and should not be construed as being preferred or superior to other embodiments or design solutions. The use of terms such as "further," "exemplary," or "optionally" is intended to present related concepts in a specific manner.

[0013] The embodiments of the present application may be used in various communication systems, such as a Global System of Mobile communication (GSM) system, a Code Division Multiple Access (CDMA) system, a Wideband Code Division Multiple Access (WCDMA) system, a General Packet Radio Service (GPRS), a Long Term Evolution (LTE) system, an Advanced long term evolution (LIE-A) system, a Universal Mobile Telecommunication System (UMTS), 5G, Beyond Fifth Generation (B5G), and a 6th Generation (6G) system, and the embodiments of the present application are not limited thereto.

[0014] The embodiments of the present application may be used in user terminals such as mobile phones and tablet PCs, in vehicle network communication devices such as smart automobiles and road side units (RSUs), in Internet of Things communication devices such as smart robots, robot arms, and wireless sensors, in smart metasurfaces, wireless relays, and other wireless mobile terminals, and the embodiments of the present application are not limited thereto.

[0015] The operation of a communication device generally requires electrical energy, and there are various ways to provide electrical energy to the communication device. In order to describe the technical solution in detail, different application scenarios are taken as examples to further explain and explain the power supply and charging of communication devices.

[0016] FIG. 1 is a schematic diagram of wired power supply. As shown in FIG. 1, a communication device, such as a base station 100, is powered through a power line for normal operation. With the expansion of network demand, more and more communication devices are used. With the increase of communication devices, the wired power supply or charging method is more and more difficult to deploy and install power lines. In addition, application scenarios such as smart home and industrial Internet of Things involve a large number of communication devices, but the space is generally limited, so that if a wired power supply or charging method is adopted, it is difficult to fully apply to this new application scenario, and the flexibility of device movement is also limited.

[0017] FIG. 2 is a schematic diagram of wireless charging. As shown in FIG. 2, a communication device, for example, a user terminal 200, is charged wirelessly for normal operation. However, the related art adopts a magnetic resonance or induction charging method. Magnetic resonance charging uses a time-varying magnetic field to generate an induced current on an induction coil to charge, whereas induction charging uses a short-distance induction field to generate resonance at the receiving end to realize energy transfer. As can be seen, the above wireless charging method is applied to short-distance charging (generally centimeter-level to meter-level), and has limited application scenarios, for example, it is difficult to meet scenarios where communication devices such as wireless communication networks are far away (tens of meters to several kilometers).

[0018] In some other application scenarios, such as the Internet of Things, the terminal directly converts the received electromagnetic signal into energy for signal transmission. This power supply and charging adopts backscattering technology, and the wireless charging distance is longer than that of magnetic resonance and induction, but it is still limited. In addition, this technology can only be applied to low receiving power, intermittent and extremely low rate wireless communication, so the application scenarios are limited.

[0019] Fig. 3 is a schematic diagram of battery power supply. As shown in Fig. 3, a communication device, such as an Internet of Things device 300, is powered through a built-in battery for normal operation. However, when relying on the power supply from the built-in battery, the normal operation time is highly dependent on the battery life, which restricts the development of the Internet of Things.

[0020] The embodiments of the present application provide a communication device and equipment, and provide energy to the communication device by installing a phase modulation circuit, a charging circuit, and an antenna, and converting an electromagnetic signal into electrical energy, thereby realizing long-distance wireless power supply and charging of the communication device, reducing the number of power supply lines, improving the flexibility of the use and installation deployment of the device, and reducing installation and maintenance costs. Some other embodiments of the present application provide a base station, and install a communication device capable of long-distance wireless charging, thereby reducing the complexity of the base station location and power supply line planning, and also significantly reducing the maintenance management costs after construction.

[0051] In one embodiment, the communication device has a wireless charging mode and a wireless communication mode. In the wireless charging mode, the communication device receives an electromagnetic signal (hereinafter also referred to as an energy signal for ease of distinction) emitted from the outside, converts the received signal into electrical energy, and may be used for internal power supply. In the wireless communication mode, the communication device receives an electromagnetic signal emitted from the outside, and processes the received signal to obtain information contained in the signal. The processing of the electromagnetic signal may include filtering, amplification, noise reduction, demodulation, decoding, etc. For ease of description, the electromagnetic signal received in this mode is referred to as an information signal. The electromagnetic signal received in the wireless charging mode and the electromagnetic signal received in the wireless communication mode may be the same type of signal or different types of signals, for example, signals of the same frequency or different frequencies, and may be signals from the same emission source or different emission sources.

[0052] In one embodiment, the communication device may set the operation mode according to time, for example, in one time period, the communication device may be in a wireless charging mode operation mode, and in another time period, the communication device may be in a wireless communication mode operation mode.

[0053] In another embodiment, the communication device may be in two operating modes simultaneously, i.e., processing some of the received electromagnetic signals to obtain information contained in the signals, and converting other parts of the received electromagnetic signals into electrical energy for internal use.

[0054] To describe in more detail the operation mode of a communication device according to one embodiment of the present application, the operation mode of the communication device will now be described with reference to FIG.

[0055] Fig. 12 is an operation schematic diagram of a communication device according to an embodiment of the present application. As shown in Fig. 12, the communication device operates in a first operation mode M1 during a time period t1-t3, and operates in a second operation mode M2 ​​during a time period t2-t4, and the two time periods have an overlapping time interval, i.e., t2-t3, during which the communication device operates in two modes at the same time, and can communicate and charge at the same time. The first operation mode M1 can be a wireless charging mode or a wireless communication mode, and the second operation mode M2 ​​can be a wireless communication mode or a wireless charging mode.

[0056] When the communication device simultaneously activates the two operating modes M1 and M2, in order to avoid mutual interference between the information signal and the energy signal, it may use different operating frequency bands, i.e., the wireless communication uses a part of a sub-band of the available frequency band, and the wireless charging uses another part of the sub-band, and the two sub-bands may be continuous frequency bands or segmented frequency bands.

[0057] FIG. 13 is a schematic diagram of the operation of communication devices in different frequency bands in some embodiments of the present application. As shown in FIG. 13(a), among the available frequency bands f1-f3, the f1-f2 subbands are used for wireless charging, and the f2-f3 subbands are used for wireless communication. Meanwhile, as shown in FIG. 13(b), the available frequency band is divided into multiple subbands, and wireless charging and wireless communication use these subbands respectively. In future communication systems, there may be multiple available frequency bands among communication devices, such as sub-6G, millimeter wave, terahertz frequency bands, and at this time, in each available frequency band, the frequency resource division shown in FIG. 13 can still be adopted for wireless charging and wireless communication.

[0058] In one embodiment, the communication device performs wireless communication and wireless charging using the same frequency. To avoid interference between the information signal and the energy signal, they may be performed at different time periods. For example, wireless communication is performed at time period 1, and wireless charging is performed at time period 2, and there is no intersection between time period 1 and time period 2. When wireless charging and wireless communication are performed at different times, the communication device can improve the signal-to-noise ratio of the transmitted and received signals by selecting and using all antennas available for information transmission and reception in the wireless communication mode for communication. Similarly, the communication device can improve charging efficiency by using all antennas available for energy reception in the wireless charging mode for receiving the energy signal.

[0059] In one embodiment, the communication device uses the same frequency for wireless communication and wireless charging. In order to avoid interference between the information signal and the energy signal, different antennas may be used to receive the information signal and the energy signal. A typical scenario is that the information signal and the energy signal come from different directions, and different receiving arrays are used to receive the information signal and the energy signal, respectively, to reduce interference.

[0060] In one embodiment, when the same antenna is required for two working modes of the communication device, the wireless communication mode and the wireless charging mode may be performed in different time periods to avoid signal interference, for example, time period 1 is used for wireless communication and time period 2 is used for wireless charging, and time period 1 and time period 2 have no intersection.

[0061] In one embodiment, while the same antenna is required for both operational modes of the communications device, the wireless communication mode and the wireless charging mode may use different frequency bands.

[0062] In one embodiment, an information signal radiated from outside has a wide beam and can be simultaneously received by an information receiving antenna and an energy receiving antenna of the communication device, the information signal received by the information receiving antenna is used for signal processing, and the information signal received by the energy receiving antenna is converted into electrical energy via a charging circuit.

[0063] In another embodiment, when the first operating mode M1 and the second operating mode M2 ​​are not turned on simultaneously, the operating mode switching of the communication device may adopt coordinated state control, i.e., coordinated control between turning on the wireless charging mode and turning off the wireless communication mode, and coordinated control between turning off the wireless charging mode and turning on the wireless communication mode, in order to reduce the control circuit and control signaling.

[0064] When the communication device operates in a wireless charging mode, electromagnetic signals received by the device are converted into electrical energy via a charging circuit, which may include circuit elements such as capacitors (including fixed capacitors and variable capacitors), inductors, diodes, field effect transistors, etc.

[0065] In one embodiment, the communication device may set the working mode according to the power supply situation. For example, after the communication device is charged for a long time, when the converted electric energy can provide sufficient power supply for the communication device, the wireless charging mode may be turned off to extend the service life of the charging module. When the communication device has no communication demand or the power supply is insufficient, the wireless communication mode may be turned off to reduce the energy consumption of the device. When the communication device needs continuous communication but the internal power supply is tight, the communication device may work in the wireless charging mode and the wireless communication mode simultaneously. The communication device may freely switch between the two different modes according to actual needs.

[0066] The communication device may have various operating modes in the wireless communication mode, for example, a communication transceiver mode and an electromagnetic regulation mode.

[0067] In the communication transmission / reception mode, the communication device can receive an electromagnetic signal through an information receiving antenna and process the received signal to obtain information contained in the signal, while it can also spontaneously emit an electromagnetic signal containing information to the outside through the information receiving antenna. The communication device can be used to transmit and receive information at the same time, or can be used to receive information in one time period and to transmit information in another time period. This operating method is mainly applied to communication devices that provide wireless access services (e.g., new base stations), personal mobile terminal type communication devices that require wireless access services (e.g., smartphones), and Internet of Things terminal type communication devices (e.g., various sensors).

[0068] In one embodiment, a communication device can provide wireless access services to other communication devices. The communication device broadcasts the wireless access services it provides through an information receiving antenna, and one communication device can send a wireless access request to the communication device after receiving the broadcast information, and the communication device receives the wireless access request through the information receiving antenna, sends information to the communication device through the information receiving antenna, checks whether to establish a connection, and provides a wireless communication service to the communication device after determining to establish the connection. In this embodiment, the communication device has the function of a communication base station.

[0069] In another embodiment, the communication device requests wireless access service from another communication device. The communication device receives a broadcast signal of the other communication device through an information receiving antenna, and confirms from the received broadcast signal that the other communication device can provide wireless access service, and the communication device transmits a signal to the communication device through its information receiving antenna to request an access wireless network, and monitors a response signal of the communication device through the information receiving antenna, and after confirming that the communication device connects, the communication device can exchange information with the other communication device through the communication device. In this embodiment, the communication device has the functions of a mobile communication terminal and an Internet of Things terminal.

[0070] When the communication device operates in the electromagnetic adjustment mode, the electromagnetic signal radiated from the outside to the communication device is received by the information receiving antenna, and then the phase is changed through the phase modulation circuit, and the communication device performs one of the following operations on the electromagnetic signal that has finally been phase adjusted: 1) reflecting the electromagnetic signal from the side where the signal is received to the outside; 2) transmitting the electromagnetic signal from the other side of the communication device to the outside; or 3) simultaneously reflecting and transmitting the electromagnetic signal so that the received electromagnetic signal propagates along two different directions. In this working mode, the communication device plays the role of changing the propagation direction of the incident electromagnetic signal, and through appropriate phase adjustment, the electromagnetic signal containing information can be accurately propagated to a predetermined information receiving end or energy receiving end. Therefore, in this working mode, the communication device can play the role of relaying information and energy.

[0071] In one embodiment, the communication device receives electromagnetic signals radiated from the outside through its N receiving antennas, and the electromagnetic signals are phase-modulated by a phase modulation circuit after passing through the information receiving antenna of the communication device, and then reflected. The phase modulation circuits connected to the N antennas can perform the same or different phase adjustments on the received signals, thereby changing the propagation direction or changing the distribution width of the signal in the spatial propagation path after the received electromagnetic signals are reflected by the communication device.
