Non-standalone (NSA) networking is a solution for the transition from the fourth generation mobile communication technology (4G) to 5G. In the mobile communication network, mobile terminals can establish dual connections with 4G base stations and 5G base stations at the same time, and use the wireless resources of at least two different base stations at the same time.

[0054] The above drawings illustrate specific embodiments of the present application, which will be described in more detail below. These drawings and the textual description are not intended to limit the scope of the present application in any way, but rather to illustrate the concepts of the present application to those skilled in the art by reference to specific embodiments. DETAILED DESCRIPTION

[0055] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0056] Figure 1 The NSA network architecture diagram provided in this embodiment is shown in FIG. The application scenario of this embodiment is the NSA network architecture. Figure 1 As shown in the figure, under the Option 3 series NSA networking architecture, the 5G base station 11 (next generation nodeB, gNB) is connected to the 4G core network 10. Since this networking architecture is a dual connection between the 4G base station 12 (evolved nodeB, eNB) and the 5G base station 11, and the 4G base station 11 is the anchor point, this architecture is also called EN-DC (eNB NR Dualconnection), which includes the 4G core network 10, 4G base station 12, and 5G base station 11. Among them, the dotted line represents the control plane, indicating the transmission of management and call commands, and the solid line represents the user plane, indicating the transmission of user-specific data.

[0057] Exemplarily, the terminal device 13 may be a user equipment (UE), which is a device that provides voice or data connectivity to a user. Exemplarily, the terminal device 13 may transmit a first radio frequency signal to the 4G base station 12 and a second radio frequency signal to the 5G base station 11.

[0058] In real-life applications, the distance between a terminal device and a base station can vary. For example, a terminal device may be closer to a 4G base station but farther from a 5G base station. However, in the prior art, the transmit power of the first RF signal and the transmit power of the second RF signal are fixed, and their sum does not exceed the total transmit power of the terminal device. For example, if the total transmit power of the terminal device is 23dBm, the transmit power of the first RF signal may be 15dBm, and the transmit power of the second RF signal may be 8dBm. This prior art approach may prevent terminal devices from being able to sense each other with 5G base stations in some marginal areas, resulting in lower uplink performance and affecting data transmission efficiency.

[0059] To address the above-mentioned issues, the embodiments of the present application provide a power sharing method, apparatus, and electronic device. By sharing the idle transmission power when the terminal device communicates with the 4G base station and communicating with the 5G base station, the perception between the terminal device and the 5G base station can be improved, the uplink performance can be improved, and the data transmission efficiency can be improved.

[0060] The technical solution of the present application is described in detail below through specific embodiments. It should be noted that the following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0061] Figure 2 This is a flow chart of the first embodiment of the power sharing method provided in the present application. The method can be applied to terminal devices, such as mobile phones. Figure 2 As shown, the method may specifically include the following steps:

[0062] S201. Obtain a first transmission power required for communicating with a 4G base station and a second transmission power required for communicating with a 5G base station.

[0063] For example, a 4G base station and a 5G base station may send a control instruction to a terminal device via a downlink control signal. The control instruction may include a specific reference signal with a fixed power value, the maximum allowable power of the 4G base station, or the maximum allowable power of the 5G base station. After receiving the control instruction, the terminal device may measure the power of the reference signal, obtain the path loss between the terminal device and the 4G base station or the 5G base station, and calculate the usable first transmit power and second transmit power based on the maximum allowable power.

[0064] Exemplarily, the 4G base station and the 5G base station can also allocate transmit power to the terminal device based on the current network environment. Exemplarily, the transmit power allocated to the first RF signal can be 15dBm, and the transmit power of the second RF signal can be 8dBm (the sum of the transmit power of the first RF signal and the transmit power of the second RF signal cannot exceed the total transmit power of the terminal device). Among them, the transmit power allocated by the 4G base station is the first transmit power required for the terminal device to communicate with the 4G base station, and the transmit power allocated by the 5G base station is the second transmit power required for the terminal device to communicate with the 5G base station.

[0065] S202: Calculate a target shared power according to a preset first transmit power threshold and the first transmit power.

[0066] The first transmit power threshold is used to indicate a transmit power threshold when the terminal device communicates with the 4G base station. Exemplarily, the first transmit power threshold is set by the terminal device and can be set specifically according to the frequency band of the terminal device.

[0067] In this embodiment, the target shared power can be determined based on the difference between the first transmit power threshold and the first transmit power. The first transmit power does not exceed the first transmit power threshold. For example, the preset first transmit power threshold can be 23 dBm. When the first transmit power is 23 dBm, the target shared power is 23 dBm-23 dBm=0 dBm. When the first transmit power is 1 dBm, the target shared power is 23 dBm-1 dBm=22 dBm.

[0068] S203. Determine the actual transmit power for communicating with the 5G base station based on the preset second transmit power threshold, the second transmit power, and the target shared power.

[0069] Among them, the second transmit power threshold is used to indicate the transmit power threshold when the terminal device communicates with the 5G base station. Exemplarily, the second transmit power threshold is also set by the terminal device, and can be set specifically according to the frequency band of the terminal device. Exemplarily, when the value of the target shared power is not zero, the terminal device can adjust and update the value of the second transmit power threshold. For example, if the target shared power is 3dBm and the current second transmit power threshold is 10dBm, then the adjusted updated value of the second transmit power threshold = target shared power + current second transmit power threshold = 13dBm.

[0070] In this embodiment, the actual transmit power is used by the terminal device to transmit the second radio frequency signal to communicate with the 5G base station according to the actual transmit power. Exemplarily, the actual transmit power does not exceed the preset second transmit power threshold.

[0071] For example, the preset first transmit power threshold can be 13dBm, the preset second transmit power threshold can be 10dBm, the first transmit power can be 10dBm, and the second transmit power can be 12dBm. The target shared power is 3dBm, meaning that when the terminal device communicates with the 4G base station, there is idle shared power. However, the second transmit power required for communication between the terminal device and the 5G base station is greater than the preset second transmit power threshold. To ensure normal communication between the terminal device and the 5G base station, the terminal device can share the target shared power for communication with the 5G base station. That is, the actual transmit power can be taken as [the sum of the preset second transmit power threshold and the target shared power, plus the second transmit power].

[0072] S204. Communicate with the 4G base station according to the first transmission power.

[0073] In this embodiment, the terminal device can control the hardware of the terminal device, such as the RF circuit, modem and antenna, according to the first transmission power to transmit signals, that is, control the transmission power of the first RF signal to the first transmission power to achieve communication with the 4G base station.

[0074] S205. Communicate with the 5G base station according to the actual transmission power.

[0075] In this embodiment, the terminal device can control the hardware of the terminal device, such as the RF circuit, modem and antenna, according to the actual transmission power to transmit signals, that is, control the transmission power of the second RF signal to the actual transmission power to achieve communication with the 5G base station.

[0076] The embodiment of the present application shares the idle transmission power when the terminal device communicates with the 4G base station for communication between the terminal device and the 5G base station. Under the premise of ensuring stable communication between the terminal device and the 4G base station, it can improve the communication strength between the terminal device and the 5G base station, improve the perception between the terminal device and the 5G base station, achieve improved uplink performance, and improve data transmission efficiency.

[0077] In some embodiments, when calculating the target shared power, the following steps may be specifically included:

[0078] Calculating a difference between a preset first transmit power threshold and the first transmit power;

[0079] According to the difference, the power sharing interval is determined;

[0080] A target power value is selected in the power sharing interval as the target shared power.

[0081] For example, if the preset first transmit power threshold is 13dBm and the first transmit power is 10dBm, the difference between the two is 3dBm. The difference of 3dBm is taken as the upper limit of the power sharing interval. For example, the lower limit of the power sharing interval is 0, and the resulting power sharing interval is [0, 3].

[0082] For example, the target shared power may be set to an upper limit of 3dBm or a lower limit of 0dBm. For example, the terminal device may randomly select a value from the power sharing interval according to a random algorithm as the target shared power.

[0083] By calculating the power sharing interval, the embodiment of the present application can share the idle power existing when the terminal device communicates with the 4G base station, and supply it to the terminal device for communication with the 5G base station. It can increase the transmission power of the second radio frequency signal, enhance the perception of the terminal device and the 5G base station, and achieve improved uplink performance.

[0084] In some embodiments, the above step S203 can be implemented by the following steps:

[0085] comparing the preset second transmit power threshold with the second transmit power;

[0086] If the preset second transmit power threshold is greater than or equal to the second transmit power, determining the first power range according to the preset second transmit power threshold and the second transmit power;

[0087] An actual power value is selected in the first power interval as the actual transmit power;

[0088] If the preset second transmit power threshold is smaller than the second transmit power and the target shared power is zero, the second transmit power threshold is selected as the actual transmit power.

[0089] Specifically, the preset second transmit power threshold is pre-set by the terminal device, for example, a value of 10dBm. The second transmit power indicates the transmit power requirement required for communication between the terminal device and the 5G base station. When the second transmit power threshold is greater than or equal to the second transmit power, it indicates that the current terminal device can meet the transmit power requirement required for communication between the terminal device and the 5G.

[0090] For example, if the second transmit power is 8 dBm, the first power range is [8, 10]. The actual transmit power can be taken from the first power range, for example, 8 dBm or 10 dBm.

[0091] In this embodiment, if the second transmit power is 11dBm, that is, greater than the preset second transmit power threshold of 10dBm, and the target shared power is 0dBm, the actual transmit power cannot exceed the current preset second transmit power threshold and can only be 10dBm.

[0092] The embodiment of the present application can maximize the value of the actual transmission power and improve the communication power between the terminal device and the 5G base station as much as possible by determining the values and size relationship of the preset second transmission power threshold, the second transmission power and the target shared power.

[0093] In some embodiments, if the target shared power is not zero, the above step S203 can be implemented by the following steps:

[0094] If the preset second transmit power threshold is less than the second transmit power and the target shared power is not zero, calculating the sum of the preset second transmit power threshold and the target shared power;

[0095] Determining a second power range according to the sum value and the second transmit power;

[0096] An actual transmit power value is selected in the second power range as the actual transmit power.

[0097] Exemplarily, if the preset second transmit power threshold is 10dBm, the second transmit power is 11dBm, and the target shared power is 3dBm, the upper limit value of the second power interval can be the sum value, and the lower limit value is the second transmit power, that is, the second power interval is [11, 13].

[0098] For example, in one embodiment, the actual transmit power may be the minimum value in the second power range of the dimension, that is, 11 dBm, or may be 13 dBm.

[0099] The embodiment of the present application shares the target shared power to enable the terminal device to communicate with the 5G base station, thereby increasing the transmission power of the second radio frequency signal, improving the uplink performance, and improving data transmission efficiency.

[0100] In some embodiments, obtaining the first transmit power may be achieved through the following steps:

[0101] Obtaining a first power control instruction and a first data service transmission requirement transmitted by a 4G base station;

[0102] A first transmit power is calculated according to the first power control instruction and the first data service transmission requirement.

[0103] In this embodiment, the first power control instruction may be a control signal transmitted by the 4G base station to the terminal device via a downlink control channel, which includes a specific reference signal with a fixed power value, a maximum allowed power, etc. The first data service transmission requirement may be determined based on the current network environment, such as an actual data service transmission requirement required for communication between the terminal device and the 4G base station.

[0104] Optionally, in some embodiments, obtaining the second transmit power may be achieved through the following steps:

[0105] Obtain a second power control instruction and a second data service transmission requirement transmitted by the 5G base station;

[0106] A second transmit power is calculated according to the second power control instruction and the second data service transmission requirement.

[0107] In this embodiment, the second power control instruction may be a control signal transmitted by the 5G base station to the terminal device via a downlink control channel, which includes a specific reference signal with a fixed power value, a maximum allowed power, etc. The second data service transmission requirement may be determined based on the current network environment, such as the actual data service transmission requirement required for communication between the terminal device and the 5G base station.

[0108] In some embodiments, the power sharing method may further include the following steps:

[0109] In response to the terminal device being turned on, obtaining a power transmission threshold of the terminal device;

[0110] According to the power transmission threshold, a preset first transmission power threshold and a preset second transmission power threshold are determined.

[0111] In this embodiment, when a terminal device is turned on, its power transmission threshold, i.e., total transmit power, can be determined. Specifically, according to relevant requirements in the communications field, the transmit power of RF signals from a terminal device, such as a mobile phone, should not exceed a specified value during communication, as this can easily pose a risk to the human body. The transmit power of a terminal device can be set lower for different frequency bands.

[0112] The sum of the preset first transmit power threshold and the preset second transmit power threshold should not exceed the power transmit threshold. The preset first transmit power threshold and the preset second transmit power threshold can take different values in different frequency bands according to the corresponding relationship.

[0113] Figure 3 The flowchart of the second embodiment of the power sharing method provided in the embodiment of the present application is as follows: Figure 3 As shown, the method may specifically include the following steps:

[0114] S301. After being powered on, the terminal device determines a preset first transmit power threshold and a preset second transmit power threshold in an NSA network.

[0115] Among them, the preset first transmission power threshold and the preset second transmission power threshold can be preset by the terminal device and can be set separately in different frequency bands.

[0116] S302. When the terminal device is in an NSA network and has data to be transmitted, the terminal device calculates a first transmission power according to a first power control instruction and a first data service transmission requirement.

[0117] S303: Calculate and obtain a target shared power according to a preset first transmit power threshold and the first transmit power.

[0118] Exemplarily, the target shared power=max{preset first transmit power threshold-first transmit power, 0}.

[0119] S304: Calculate a second transmit power according to the second power control instruction and the second data service transmission requirement.

[0120] S305: Determine whether the second preset transmit power threshold can meet the second transmit power.

[0121] The second preset transmit power threshold is compared with the second transmit power. If the second preset transmit power threshold is greater than or equal to the second transmit power, the condition is satisfied. If the second preset transmit power threshold is less than the second transmit power, the condition is not satisfied.

[0122] If the conditions are met, then in step S3051 , the actual transmit power is calculated according to the second preset transmit power threshold and the second transmit power.

[0123] Exemplarily, actual transmit power=min{second preset transmit power threshold, second transmit power}.

[0124] If it cannot be satisfied, proceed to step S306.

[0125] S306: Determine whether the target shared power is zero.

[0126] When the target shared power is zero, it means that there is no idle transmit power shared when the terminal device communicates with the 4G base station. At this time, return to step S3051 to calculate the actual transmit power = min{second preset transmit power threshold, second transmit power}.

[0127] If the target shared power is not zero, the actual transmit power may be calculated according to step S3061 based on the second transmit power threshold, the target shared power, and the second transmit power.

[0128] Exemplarily, actual transmit power=min{second preset transmit power threshold+target shared power, second transmit power}.

[0129] S307: Control the hardware radio frequency device of the terminal device to transmit signals and perform data transmission according to the first transmission power and the actual transmission power.
