[0002] The present application relates to the technical field of wireless communication; more particularly, it relates to a cellular radiation type wireless charging method, device, storage medium and computer program product. BACKGROUND

[0003] In recent years, energy problems have become an important constraint on global economic development, and it is urgent to develop clean and renewable energy. Today, various types of electrical equipment can be found everywhere in daily life and various industries, continuously improving people's quality of life and promoting economic development. Traditional power transmission relies on wire connections, but as the level of social electrification continues to improve, people's demand for more flexible and convenient wireless power transmission technology is increasing. Wireless power transmission can achieve energy transfer without physical contact between the power source and the electrical equipment, so it is receiving more and more attention.

[0004] Wireless power transmission is mainly divided into two ways, the first is electromagnetic induction coupling, which is derived from electromagnetic induction. The sending end realizes "electricity to magnetism", and the receiving end realizes "magnetism to electricity". Although electromagnetic induction coupling can output high power and has high transmission efficiency, it is suitable for short-distance charging and cannot achieve long-distance charging. Therefore, this technology is difficult to promote widely in cellular networks. The second is microwave radiation type. The microwave wireless energy transmission system mainly consists of two parts: the transmitting antenna system and the receiving rectenna system. The transmitting antenna system converts direct current energy into radio frequency energy and radiates radio frequency energy into free space. The receiving rectenna collects radio frequency energy signals in the surrounding environment, and then converts the radio frequency energy signals into direct current energy signals for subsequent load use. Microwave radiation type energy transmission can transmit power over long distances, and has shown a very broad application prospect in many fields.

[0040] To make the objectives, technical solutions, and advantages of the present application clearer, the following will further describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings.

[0041] In recent years, the application of wireless energy transmission in a cellular network has become a focus of academic research. However, in a cellular network, the distance between a base station and a user terminal is far, and the channel is complex, so microwave radiation is considered to be a more suitable energy transmission scheme. Meanwhile, energy transmission service is different from traditional communication service, and an energy transmission user terminal does not need to access a base station without energy transmission function. To ensure the smooth progress of energy transmission service, the base station needs to provide the energy transmission support information of the base station to the user terminal before the initial access of the user terminal.

[0042] On the one hand, although both the energy transmission signal and the communication signal are electromagnetic wave signals, the communication signal transmits unknown bits, and the energy transmission signal transmits energy. However, the multi-user differentiation of the energy transmission signal is completely different from that of the communication signal. The communication signal can achieve communication with only the target user through a specific scrambling code, while the energy transmission signal receiver only collects microwave signals for analog rectification and does not perform digital operation, so it is impossible to differentiate multiple users through scrambling. If the microwave energy transmission is directly sent to the user terminal, it will cause the risk of illegal collection of the energy by other users. Therefore, it is necessary to realize the directional energy transmission of the base station to the target user to avoid the illegal collection of energy by other users, i.e., to solve the problem of "stealing electricity".

[0043] On the other hand, the time-varying characteristics of the cellular network channel limit the efficiency of microwave radiation type wireless energy transmission. Compared with wireless communication, the energy transmission system is more sensitive to transmission path loss. Wireless communication can compensate for the effects of path loss through digital processing technology, while the energy transmission signal is directly rectified by analog, and the receiving end can only receive the actual transmitted energy and cannot be compensated. Therefore, microwave energy transmission relies on the stability of the channel, and the time-varying nature of the channel causes changes in its frequency characteristics, thereby reducing the energy transmission efficiency of the fixed frequency band. With the dynamic changes in channel conditions, some frequency bands may experience energy transmission attenuation, thereby affecting the overall energy transmission effect. Therefore, in view of the frequency characteristics of the time-varying channel, the fixed frequency band energy transmission method faces a large efficiency loss.

[0044] In addition, the existing wireless charging protocol QI protocol only considers basic processes such as user identity and charging information reporting, safety detection, etc. However, these protocols do not consider the problems of long-distance target user directional energy transmission and channel time-varying. Therefore, it is urgent to propose a charging protocol suitable for long-distance microwave radiation type energy transmission to solve the deficiencies of existing protocols in long-distance energy transmission applications.

[0045] In the cellular network, the energy transmission user terminal needs to obtain information about whether the base station supports energy transmission as soon as possible, but the current broadcast information does not contain this information; In the cellular network, the dense user networking puts higher requirements on the target user directional transmission capability of the energy transmission signal, but there is currently no effective method to solve the problem of target user directional energy transmission and prevent illegal users from obtaining energy in violation of regulations; In the cellular network, the channel between the base station and the user terminal is time-varying, and its frequency domain characteristics are very complex and variable. If the energy transmission signal is only transmitted in some frequency bands, it may result in low average transmission efficiency. Therefore, it is necessary to dynamically adjust the time and frequency resources of energy transmission through reasonable protocol design to ensure efficient energy transmission.

[0046] To this end, some embodiments of the present application provide a cellular radiation type wireless charging method to realize directional energy transmission of target users in a cellular network, prevent illegal users from obtaining energy in violation of regulations, and improve energy transmission efficiency.

[0047] FIG. 1 is a flowchart of a cellular radiation type wireless charging method provided by some embodiments of the present application. As shown in FIG. 1, the cellular radiation type wireless charging method can be executed by a user terminal, and the method comprises:

[0048] Step S110. The user terminal receives the SIB1 message sent by the base station, and the SIB1 message contains a transmission function indication bit for indicating whether the base station has energy transmission capability.

[0049] In some embodiments, the information carried by the SIB1 is added according to the agreement TS 38.331 between the user terminal and the base station in the downlink synchronization process, and the user terminal is informed in advance of the energy transmission capability information of the base station, i.e., whether the base station has the energy transmission capability, based on the added information carried by the SIB1.

[0050] Step S120. If the user terminal determines that the base station has the energy transmission capability based on the energy transmission function indication bit, the user terminal sends an energy transmission request to the base station, negotiates the energy transmission frequency band with the base station, and receives the energy transmission frequency hopping code issued by the base station, which carries the time-frequency resource allocation information.

[0051] In some embodiments, the corresponding protocol procedure is designed through the technical route of frequency hopping between the user terminal and the base station with energy transmission capability, to uniquely determine the energy transmission frequency band of the base station and the legitimate user terminal.

[0052] Step S130. The user terminal receives the energy transmitted by the base station to the user terminal according to the auxiliary information, wherein the auxiliary information contains the time-frequency resource allocation information carried by the energy transmission frequency hopping code.

[0053] In some embodiments, the corresponding protocol procedure is designed according to the measurement feedback scheme for optimizing the energy transmission efficiency between the user terminal and the base station with energy transmission capability, to improve the energy transmission efficiency. The base station transmits a reference signal to the user terminal at a frequency point in the energy transmission frequency band, the user terminal measures and reports the channel frequency domain characteristic information in the energy transmission support frequency band to the base station, and the base station selects a frequency band with high transmission efficiency for energy transmission according to the channel frequency domain characteristic.

[0054] As a specific step of the embodiment, the specific agreement between the user terminal and the base station with energy transmission capability in step S110 is TS 38.331. FIG. 2 is a protocol flow chart of the signaling interaction related to wireless energy transmission between the cellular network base station and the user terminal in the cellular radiation type wireless charging method provided by some embodiments of the present application. As shown in FIG. 2:

[0055] S201: In the cell search process, the SIB1 message transmitted by the base station adds an energy transmission function indication bit, which is used to identify whether the base station has the energy transmission capability;

[0056] S202: The user terminal and the base station perform the communication conventional random access procedure (Random Access Procedure);

[0057] S203: The user terminal and the base station perform the communication conventional authentication procedure (Identity / Authentication / Security);

[0059] S205: The base station sends a channel measurement to the user terminal, which contains a reference signal for measuring the channel frequency characteristics in the power transfer frequency band;

[0060] S206: The user terminal reports a power transfer configuration to the base station, which includes power configuration information, user terminal device supported power transfer frequency band, and channel state information of the power transfer frequency band;

[0061] S207: The base station sends an assistance message to the user terminal, which contains time-frequency resource allocation information carried by the power transfer frequency hopping code;

[0062] S208: The user terminal reports an assistance message response to the base station, ensuring that the user terminal and the base station's transceiver frequency hopping sequence is aligned;

[0063] S209: Based on the assistance message, the base station transmits power to the user terminal;

[0064] S210: The user terminal dynamically reports a charge status report to the base station, and the base station periodically sends a reference signal to enable the user terminal to update and report slow time-varying channel frequency characteristics. The user terminal also needs to dynamically report the required charging power time, current power transfer frequency efficiency, and other information.

[0066] Step S310, the base station indicates whether the base station has power transfer capability by adding a power transfer function indication bit in the SIB1 message;

[0067] Step S320, the user terminal determines whether the SIB1 message contains a power transfer function indication bit. If the SIB1 message contains a power transfer function indication bit, it is determined that the base station has power transfer capability, and user terminals with power transfer requirements can access the base station. If the SIB1 message does not contain the power transfer function indication bit, it is determined that the base station does not have power transfer capability, and user terminals with power transfer requirements do not need to access the base station.

[0068] As a specific step of the embodiment, as shown in FIGS. 4-6, step S120 can include:

[0069] In step S410, the user terminal reports the frequency range of the supported energy transmission frequency band and the channel measurement result to the base station.

[0070] In some embodiments, S410 can include:

[0071] receiving the channel measurement sent by the base station, which contains the reference signal for measuring the channel frequency characteristics in the energy transmission frequency band;

[0072] reporting the energy transmission configuration to the base station, which includes the energy configuration information, the energy transmission frequency band supported by the user terminal device, and the channel state information of the energy transmission frequency band.

[0073] In step S420, the user terminal receives the assistance information sent by the base station, wherein the assistance information contains the time-frequency resource allocation information carried by the energy transmission frequency hopping code.

[0074] The base station generates a frequency hopping pattern (for example, the frequency hopping pattern shown in FIG. 5) according to the frequency range and the channel measurement result reported by the user terminal, generates a frequency hopping code according to the frequency hopping pattern, and sends the frequency hopping code to the user terminal.

[0075] In step S430, after receiving the frequency hopping code, the user terminal decodes the frequency hopping pattern (for example, the frequency hopping pattern shown in FIG. 6), prepares for energy reception, and sends the assistance information response information to the base station.

[0076] FIG. 7 is another schematic diagram of the cellular radiation type wireless charging method provided by some embodiments of the present application. As a specific step of the embodiment, as shown in FIG. 7, step S120 can include:

[0077] In step S710, before the energy transmission starts, the base station receives the energy transmission request reported by the user terminal, sends the pilot in the energy transmission frequency band, and waits for the user terminal to report the measurement result to the base station.

[0078] In step S720, after receiving the pilot, the user terminal measures the pilot signal strength of each energy transmission frequency band and reports the measurement result to the base station.

[0079] In step S730, the base station determines the energy transmission frequency band according to the measurement result reported by the user terminal, and generates a frequency hopping code.

[0080] In some embodiments, the method further includes:

[0081] In step S740, after the energy transmission starts, the base station periodically sends the reference signal, the user terminal updates and reports the channel frequency characteristics, and the base station generates a new frequency hopping code.

[0082] Compared with the prior art in the technical field, the cellular radiation type wireless charging method has the following superior technical effects.

[0083] 1. The cellular radiation type wireless charging method adds a transmission energy flag carried by SIB1 signaling in the signaling interaction between the base station and the user terminal, and informs the user terminal in advance about whether the base station has transmission energy capability.

[0084] 2. The cellular radiation type wireless charging method introduces a target user directional transmission energy method based on a frequency hopping mechanism. The base station generates a frequency hopping code based on the frequency domain channel information reported by the user terminal, which is used to uniquely determine the transmission energy frequency band, thereby avoiding energy theft by illegal users and ensuring directional transmission energy for long-distance target users in the cellular network.

[0085] 3. The cellular radiation type wireless charging method also provides a transmission energy efficiency optimization measurement feedback scheme. Based on the feedback of the user terminal on the channel characteristics of the transmission energy frequency band, the base station selects the optimal frequency band for efficient transmission energy, and further improves the transmission energy efficiency by dynamically adjusting the time-frequency resources.

[0090] In some embodiments, if the user terminal determines that the base station has transmission energy capability based on the transmission energy function indication bit, the user terminal can send an energy transmission request to the base station. For example, the user terminal determines whether the transmission energy function indication bit exists in the SIB1 message. If the transmission energy function indication bit exists in the SIB1 message, it is determined that the base station has transmission energy capability, and the user terminal with transmission energy demand can access the base station. If the transmission energy function indication bit does not exist in the SIB1 message, it is determined that the base station does not have transmission energy capability, and the user terminal with transmission energy demand does not need to access the base station.
