[0023] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this disclosure.

[0024] The terminology used in this disclosure is for the purpose of describing particular embodiments only and is not intended to be limiting of the present disclosure.

[0025] It should be understood that although the terms first, second, third, etc., may be used to describe various information in embodiments of this disclosure, such information should not be limited to these terms. These terms are only used to distinguish information of the same type from one another. For example, first information may also be referred to as second information without departing from the scope of embodiments of this disclosure, and similarly, second information may also be referred to as first information. Depending on the context, the word "if" as used herein may be interpreted as "when," "when," or "in response to a determination."

[0026] For the sake of brevity and ease of understanding, this document uses the terms "greater than" or "less than", "higher than" or "lower than" to describe size relationships. However, it will be understood by those skilled in the art that the term "greater than" also includes the meaning of "greater than or equal to", and "less than" also includes the meaning of "less than or equal to"; the term "higher than" also includes the meaning of "higher than or equal to", and "lower than" also includes the meaning of "lower than or equal to".

[0027] Figure 1 This is a schematic flowchart illustrating a request sending method according to an embodiment of the present disclosure. The request sending method shown in this embodiment can be applied to a terminal, which can communicate with a base station as a user equipment or with a core network.

[0028] The terminals include, but are not limited to, communication devices such as mobile phones, tablets, wearable devices, sensors, and IoT devices. The base stations include, but are not limited to, base stations in communication systems such as 4G base stations, 5G base stations, and 6G base stations.

[0029] In one embodiment, the base station may be the base station corresponding to the cell where the terminal is currently located, and further, the base station may be wirelessly charging the terminal.

[0030] It should be noted that, in all embodiments of this disclosure, wireless charging refers to the base station wirelessly charging the terminal, wherein the method of wireless charging includes at least one of the following:

[0031] Electromagnetic induction, electromagnetic resonance, and radio frequency.

[0032] In one embodiment, the base station charges the terminal wirelessly via radio frequency, specifically through air charging.

[0033] In this context, "air-based charging" refers to a base station's ability to transmit energy to a terminal via multiple antennas in millimeter-wave and narrow-bandwidth formats. The terminal can then receive this energy through a miniature beacon antenna, converting it into electrical energy for charging. Furthermore, the ability of a base station to perform air-based charging can also refer to its ability to pinpoint the terminal's location and then transmit energy to that terminal for charging.

[0034] like Figure 1 As shown, the request sending method may include the following steps:

[0035] In step S101, a wireless charging request is sent to the base station, wherein the wireless charging request is used to request the base station to wirelessly charge the terminal.

[0036] In one embodiment, the terminal may send a wireless charging request to the base station. The triggering condition for the terminal to send the wireless charging request to the base station can be determined by at least one of the following methods: base station instruction, terminal self-determination, or communication protocol agreement between the terminal and the base station.

[0037] For example, the trigger condition is that the terminal's current remaining battery power is lower than a battery threshold (which can be a specific battery value or a battery percentage). That is, when the terminal's current remaining battery power is lower than the battery threshold, a wireless charging request is sent to the base station. Taking the terminal's own determination of the trigger condition as an example, the terminal can independently determine the battery threshold; taking the base station's indication of the trigger condition as an example, the base station can indicate the battery threshold.

[0038] Of course, the triggering condition is not limited to the terminal's current remaining battery level being lower than the battery threshold. It can be set specifically as needed. For example, it could be the time elapsed from the current moment to the last time a wireless charging request was sent to the base station, which is greater than the period threshold.

[0039] According to embodiments of this disclosure, a terminal can send a wireless charging request to a base station, enabling the base station to determine that the terminal needs wireless charging based on the request and thus provide timely wireless charging for the terminal.

[0040] In one embodiment, the wireless charging request carries wireless charging assistance information, wherein the wireless charging assistance information is used to assist the base station in wirelessly charging the terminal.

[0041] By including wireless charging assistance information in the wireless charging request, the base station can be provided with a reference to determine whether and how to wirelessly charge the terminal. It should be noted that the wireless charging assistance information is only used to assist the base station in wirelessly charging the terminal, not to instruct the base station to wirelessly charge the terminal. The base station can refer to the assistance information to determine how to wirelessly charge the terminal, or it can determine how to wirelessly charge the terminal without referring to the assistance information.

[0042] In one embodiment, the wireless charging assistance information includes at least one of the following: charging direction information; charging antenna information; wireless charging capability; spatial status information; and wireless charging status.

[0043] In one embodiment, the charging direction information is determined based on at least one of the following: the position of the terminal relative to the base station; the absolute position of the terminal and the base station; and the beam used by the terminal to communicate with the base station.

[0044] For example, the relative direction can be determined based on the terminal's position relative to the base station; the absolute direction can be determined based on the terminal's absolute position relative to the base station; or the direction can be determined based on the direction of the beam used by the terminal to communicate with the base station (either the terminal's receiving beam or the base station's transmitting beam). After determining the charging direction, the base station transmits a wireless charging signal along that direction to wirelessly charge the terminal.

[0045] In one embodiment, the wireless charging capability includes at least one of the following: wireless charging power (the power supported by the terminal in receiving wireless charging signals), wireless charging frequency domain resources (the frequency band in which the terminal can receive wireless charging signals), and wireless charging time domain resources (the time period in which the terminal can receive wireless charging signals).

[0046] After receiving the wireless charging capability, the base station can charge the terminal according to the wireless charging capability. For example, the power of the wireless charging signal can be set to the wireless charging power; for example, the wireless charging signal can be sent to the terminal in the wireless charging frequency domain resource; for example, the wireless charging signal can be sent to the terminal in the wireless charging time domain resource.

[0047] In one embodiment, the spatial state information includes at least one of the following: movement speed, movement direction, and position.

[0048] The terminal can detect its own spatial state information, such as its speed, direction of movement, and position (which can be a two-dimensional or three-dimensional position). The base station can then determine whether to wirelessly charge the terminal based on this spatial state information, and how to do so.

[0049] For example, spatial status information includes location. The base station can determine the distance between itself and the terminal based on its own location and the terminal's location. Wireless charging will only be performed on the terminal if the distance is less than or equal to a distance threshold, otherwise wireless charging will not be performed. Furthermore, when it is determined that wireless charging will be performed on the terminal, the power of wireless charging can also be determined based on the distance. For example, the power can be positively correlated with the distance, with the upper limit being the maximum value of the wireless charging power supported by the terminal.

[0050] For example, spatial state information includes movement speed. Wireless charging is only performed on the terminal when the movement speed is less than or equal to a speed threshold, and not on the other hand. Furthermore, when it is determined that the terminal will be wirelessly charged, the speed of change of the direction of wireless charging can also be determined based on the movement speed to ensure that the wireless charging direction is directed towards the moving terminal.

[0051] In one embodiment, the wireless charging status includes at least one of the following: current remaining power, power required for charging, and required charging time.

[0052] Based on the terminal's wireless charging status, the base station can determine how to wirelessly charge the terminal. For example, if the wireless charging status includes the required charging time, the base station can maintain wireless charging for that duration. Alternatively, if the wireless charging status includes the required charging amount, the base station can determine the charging time based on the required charging amount, the power of the wireless charging signal, and the efficiency of wireless charging, and continuously charge the terminal with a wireless charging signal of that power for that duration, thus fully charging the terminal.

[0053] Figure 2 This is a schematic flowchart illustrating another request sending method according to embodiments of the present disclosure. Figure 2 As shown, sending a wireless charging request to the base station includes:

[0054] In step S201, a random access message is sent to the base station, wherein the random access message carries the wireless charging request.

[0055] In one embodiment, the terminal can carry the wireless charging request in the random access message sent to the base station. This eliminates the need to send a separate wireless charging request, thus saving communication resources. Furthermore, the wireless charging request can be sent during the random access process, allowing the base station to promptly determine that the terminal needs wireless charging.

[0056] In one embodiment, the random access message includes at least one of the following: random access first message Msg1, random access third message Msg3, and random access fifth message Msg5.

[0057] It should be noted that the above random access messages mainly refer to four-step random access. In two-step random access, the random access message can be MsgA. Furthermore, wireless charging requests can be sent once or multiple times, as shown in the various random access messages mentioned above, each carrying a wireless charging request.

[0058] In one embodiment, when the terminal is in an idle or inactive state, the first random access message includes a random access preamble, wherein the preamble is used to request the base station to wirelessly charge the terminal. The preamble may be configured by the base station for the terminal specifically to request wireless charging.

[0059] In one embodiment, when the terminal is in an idle state, the third random access message includes a Radio Resource Control Establishment Request (RRCSetupRequest) message or a Radio Resource Control Re-establishment Request (RRCReestablishmentRequest) message; the fifth random access message includes a Radio Resource Control Establishment Complete (RRCSetupComplete) message or a Radio Resource Control Re-establishment Complete (RRCReestablishmentComplete) message.

[0060] In one embodiment, when the terminal is in an inactive state, the third random access message includes a Radio Resource Control Recovery Request (RRCResumeRequest) message; the fifth random access message includes a Radio Resource Control Recovery Complete (RRCResumeComplete) message.

[0061] In one embodiment, when the terminal is in a connected state, the wireless charging request is carried in the User Equipment Assistance Information (UEAssistanceInformation) or in a new signaling message, such as a RadioChargingRequest signaling message.

[0062] In one embodiment, the wireless charging request is carried in at least one of the following: Radio Resource Control (RRC) layer signaling, Medium Access Control (MAC) layer signaling, and Physical PHY layer signaling.

[0063] Figure 3 This is a schematic flowchart illustrating a request receiving method according to an embodiment of the present disclosure. The request receiving method shown in this embodiment can be applied to a base station, which can communicate with a terminal acting as a user equipment or with a core network.

[0064] The terminals include, but are not limited to, communication devices such as mobile phones, tablets, wearable devices, sensors, and IoT devices. The base stations include, but are not limited to, base stations in communication systems such as 4G base stations, 5G base stations, and 6G base stations.

[0065] like Figure 3 As shown, the request receiving method may include the following steps:

[0066] In step S301, a wireless charging request sent by the terminal is received, wherein the wireless charging request is used to request the base station to wirelessly charge the terminal.

[0067] According to embodiments of this disclosure, a terminal can send a wireless charging request to a base station, enabling the base station to determine that the terminal needs wireless charging based on the request and thus provide timely wireless charging for the terminal.

[0068] In one embodiment, the wireless charging request carries wireless charging assistance information, and the method further includes: determining at least one of the following based on the status of the base station and / or the wireless charging assistance information:

[0069] Whether to wirelessly charge the terminal, and the wireless charging configuration for wirelessly charging the terminal.

[0070] The base station can determine whether to wirelessly charge the terminal and configure the wireless charging settings based solely on its own status; alternatively, it can determine this based solely on wireless charging assistance information; or it can determine this based on both its own status and the wireless charging assistance information. The specific methods for determining these settings will be explained in subsequent embodiments.

[0071] In one embodiment, the state of the base station includes at least one of the following: the load of the base station, and the antenna usage of the base station.

[0072] In one embodiment, the wireless charging assistance information includes at least one of the following: charging direction information; charging antenna information; wireless charging capability; spatial status information; and wireless charging status.

[0073] Based on the charging direction information, the base station can determine the charging direction and transmit a wireless charging signal along that direction to wirelessly charge the terminal.

[0074] Based on the charging antenna information, the base station can determine the antenna used by the terminal to receive the charging signal, and then transmit the charging signal along the antenna to wirelessly charge the terminal.

[0075] Based on the wireless charging capability, the base station can select a configuration that matches the terminal's wireless charging capability as the wireless charging configuration and send it to the terminal; for example, the wireless charging configuration includes wireless charging power, and the base station can select a power whose difference from the wireless charging power is less than a preset difference as the power of the wireless charging signal; for example, the wireless charging configuration includes wireless charging frequency, and the base station can select a frequency that is the same as the wireless charging frequency as the frequency of the wireless charging signal.

[0076] Based on spatial state information, such as the terminal's movement speed, the base station will only wirelessly charge the terminal if the movement speed is less than or equal to a speed threshold; otherwise, it will not wirelessly charge the terminal.

[0077] Based on the wireless charging status, such as the required charging time, the base station can use that time as the duration of wireless charging.

[0078] In one embodiment, the state of the base station includes the load of the base station, and determining the wireless charging configuration for wireless charging the terminal based on the state of the base station includes: determining available resources based on the load of the base station; and determining resources for wireless charging the terminal from the available resources.

[0079] Base stations can also determine whether to wirelessly charge terminals based on their own load. For example, they will only wirelessly charge terminals when the load is below the load threshold, and not wirelessly charge terminals when the load is above the threshold.

[0080] The base station can determine available resources based on its own load, such as frequency domain resources and time domain resources. The available resources include, but are not limited to, resources that the base station has not yet allocated to other terminals. The base station can then select resources from the available resources to wirelessly charge the terminals.

[0081] In one embodiment, the state of the base station includes the antenna usage of the base station, and determining the wireless charging configuration for wireless charging the terminal based on the state of the base station includes: determining antennas that can be used for wireless charging based on the antenna usage of the base station; and determining the antenna for wireless charging the terminal from among the antennas that can be used for wireless charging.

[0082] The base station can also determine which antennas in its antenna can be used for wireless charging. The criteria for determining which antennas can be used for wireless charging include, but are not limited to, whether the antenna is currently in use (if it is not in use, it can be used for wireless charging) and the antenna's operating frequency (if the operating frequency is below the frequency threshold, it can be used for wireless charging).

[0083] For example, wireless charging will only be performed on the terminal if an antenna that can be used for wireless charging is available; otherwise, wireless charging will not be performed on the terminal.

[0084] When it is determined that the terminal will be wirelessly charged, the base station selects an antenna from the antennas that can be used for wireless charging to wirelessly charge the terminal. For example, the antenna selection conditions include, but are not limited to, whether it will be used in the future (if it will not be used, it will be selected), and whether it corresponds to the direction of the antenna used by the terminal to receive the wireless charging signal (if it corresponds, it will be selected).

[0085] In one embodiment, the wireless charging assistance information includes the wireless charging capability of the terminal, and determining whether to wirelessly charge the terminal based on the wireless charging assistance information includes: determining whether the wireless charging capability of the base station matches the wireless charging capability of the terminal; and if the wireless charging capability of the base station matches the wireless charging capability of the terminal, determining to wirelessly charge the terminal.

[0086] After determining the wireless charging capability of the terminal, the base station can determine whether its own wireless charging capability matches the terminal's wireless charging capability. For example, the terminal's wireless charging capability includes wireless charging power P1 and wireless charging frequency f1. The base station can determine whether it can wirelessly charge the terminal at power P1 and whether it can transmit a wireless charging signal to the terminal at frequency f1. If it cannot wirelessly charge the terminal at power P1 and / or cannot transmit a wireless charging signal to the terminal at frequency f1, then it is determined that its own wireless charging capability does not match the terminal's wireless charging capability; otherwise, it is determined that they match.

[0087] Once it is determined that the terminal will be wirelessly charged, the wireless charging configuration can be further determined based on the terminal's wireless charging capability. For example, the power of the wireless charging signal can be set to the wireless charging power; for example, the wireless charging signal can be sent to the terminal at the wireless charging frequency.

[0088] In one embodiment, the wireless charging assistance information includes the spatial state information of the terminal. Determining whether to wirelessly charge the terminal based on the wireless charging assistance information includes: determining the efficiency of wirelessly charging the terminal based on the spatial state information of the base station and the spatial state information of the terminal; and determining to wirelessly charge the terminal if the efficiency of wirelessly charging the terminal is higher than a preset efficiency.

[0089] After determining the spatial state information of the terminal, the base station can determine the efficiency of wireless charging for the terminal based on the spatial state information of the base station and the terminal. For example, the spatial state information includes location. The base station can determine the distance between the two based on its own location and the terminal's location, and then determine the efficiency of wireless charging based on the distance. It can also determine the obstacles between the two based on their locations, and determine the efficiency of wireless charging based on the characteristics of the obstacles (density, height, etc.).

[0090] Wireless charging is only performed when the efficiency of wireless charging is higher than the preset efficiency; otherwise, it is not performed. This helps to avoid wasting time and wireless charging resources by wirelessly charging the terminal inefficiently.

[0091] In one embodiment, the method further includes: if a wireless charging configuration for wireless charging the terminal is determined, sending the wireless charging configuration to the terminal.

[0092] Once the base station determines that it will wirelessly charge the terminal, it can further determine the wireless charging configuration, such as the wireless charging power and frequency, and then send the wireless charging configuration to the terminal. The terminal can then receive the wireless charging signal sent by the base station according to the wireless charging configuration and perform wireless charging.

[0093] In one embodiment, the wireless charging configuration carries at least one of the following: radio resource control layer signaling, medium access control layer signaling, and physical layer signaling.

[0094] In one embodiment, the wireless charging configuration carries at least one of the following: Radio Access Control Reconfiguration (RRCReconfiguration) signaling, Radio Access Control Establishment (RRCSetup) signaling, Radio Access Control Re-establishment (RCReestablishment) signaling, and Radio Access Control Resume (RRCResume) signaling.
