Fig. 1 is a diagram illustrating an application scenario of the data transmission method according to an embodiment. As shown in fig. 1, a communication connection is established between the terminal device 10 and the network device 20, optionally, the terminal device 10 and the network device 20 may establish a communication connection through communication technologies such as a fourth generation (4G) and a fifth generation (5G), and a communication connection manner of the terminal device and the network device is not limited in this embodiment.
In some embodiments, the terminal device 10 may be referred to as a User Equipment (UE). The terminal device may be a Personal Communication Service (PCS) phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), or the like, and the terminal device may also be a mobile phone, a Mobile Station (MS), a mobile terminal (mobile terminal), a notebook computer, or the like, and the terminal device 10 may communicate with one or more core networks through a Radio Access Network (RAN). For example, the terminal equipment 10 may be a mobile telephone (or so-called "cellular" telephone) or a computer with a mobile terminal, etc., and the terminal equipment 10 may also be a portable, pocket, hand-held, computer-included, or vehicle-mounted mobile device that exchanges voice and/or data with a radio access network, for example. The terminal device 10 may also be a handheld device with a wireless communication function, a computing device or other processing device connected to a wireless modem, an in-vehicle device, a wearable device, a terminal device in a network evolved in the future, and the like, and the implementation of the present application is not limited.
In some embodiments, the network device 20 may be an evolved Node B (eNB or e-NodeB) macro base station, a micro base station (also referred to as a "small base station"), a pico base station, an Access Point (AP), a Transmission Point (TP), a new generation Node B (g), or the like in a Long Term Evolution (LTE) system, an NR communication system, or a licensed assisted access long term evolution (LAA-LTE) system. The network device 20 may also be other types of network devices in a future evolution network, and the implementation of the present application is not limited.
In the embodiment of the present application, the terminal device 10 may include a radio frequency module, and transmit data to the network device 20 through the radio frequency module. When the radio frequency module of the terminal device 10 performs data transmission, the target transmission power of the radio frequency module may be obtained, and the data transmission may be performed with the target transmission power as the maximum transmission power. The target transmission power may be obtained according to currents respectively corresponding to the radio frequency module when the radio frequency module uses a plurality of different transmission powers for data transmission. In a conventional manner, the radio frequency module of the terminal device 10 generally uses a preset maximum transmission power for data transmission, resulting in a large instantaneous current during data transmission, which increases the power consumption of data transmission. In the embodiment of the present application, the target transmission power is obtained according to the currents respectively corresponding to the radio frequency module when the radio frequency module uses a plurality of different transmission powers to perform data transmission, and the target transmission power is smaller than the preset maximum transmission power of the radio frequency module.
As shown in fig. 2, in an embodiment, a data transmission method is provided, which is applicable to the terminal device described above, and the data transmission method may include the following steps:
The target transmission power may be obtained according to respective corresponding currents when the radio frequency module performs data transmission using a plurality of different transmission powers. In some embodiments, the currents respectively corresponding to the rf module using the plurality of different transmit powers for data transmission may refer to currents consumed by the rf module using different transmit powers for data transmission. The current corresponding to each transmission power may be an instantaneous current (i.e., a current at the time of transmitting data) corresponding to each transmission power when data transmission is performed, or may be a total transmission current corresponding to each transmission power when data transmission is performed. Here, the instantaneous current refers to a current consumed per unit time when data transmission is performed, and the total transmission current may refer to a total amount of current consumed for transmitting one frame of data. When the radio frequency module adopts different sending powers to transmit data, the radio frequency module can respectively correspond to different currents.
In some embodiments, when the radio frequency module performs data transmission, the radio frequency module may test currents corresponding to the radio frequency module during data transmission at a plurality of different transmission powers, and may establish a correspondence between the currents and the transmission powers according to a test result. Optionally, the plurality of different transmission powers may include a preset maximum transmission power, where the preset maximum transmission power is a default maximum transmission power of the radio frequency module, and may be preset according to an actual requirement. When a reasonable target transmission power is not selected, the radio frequency module generally performs data transmission with a preset maximum transmission power as a maximum transmission power. Some or all of the plurality of transmission powers can be selected to be tested within a range of a preset maximum transmission power and a preset minimum transmission power. For example, if the preset maximum transmission power of the rf module is 23dBm (decibel milliwatt), the rf module may test the currents corresponding to data transmission with a plurality of different transmission powers from 0dBm to 23dBm, such as the currents corresponding to data transmission with 17dBm, 18dBm, 20dBm, 21dBm, and 23dBm, or may test the currents corresponding to data transmission with each transmission power included in 0dBm to 23dBm, such as the currents corresponding to data transmission with 1dBm, 2dBm, …, and 23 dBm.
For example, in an embodiment, a correspondence between the transmission power and the current used by the rf module for data transmission may be as shown in table 1, where the current is an instantaneous current during data transmission.
TABLE 1
| Radio frequency module transmission power | Electric current |
| 17dBm | 300mA (milliamp) |
| 18dBm | 330mA |
| 19dBm | 350mA |
| 20dBm | 400mA |
| 21dBm | 460mA |
| 22dBm | 560mA |
| 23dBm | 580mA |
As can be seen from table 1, the larger the transmission power of the rf module is, the larger the corresponding current is, and if the data transmission is directly performed with the preset maximum transmission power, the consumed current ratio is larger.
The terminal device can select target sending power from a plurality of different sending powers according to currents respectively corresponding to the plurality of different sending powers, and the target sending power can be smaller than a preset maximum sending power, so that the power of the radio frequency module is reduced when data transmission is carried out. Alternatively, the target transmission power may be any one of transmission total currents, which are smaller than a preset maximum transmission power, among transmission total currents respectively corresponding to a plurality of different transmission powers. Further, the target transmission power may be the minimum transmission power of the total transmission currents corresponding to the plurality of different transmission powers, and it is ensured that the power consumption of the radio frequency module during data transmission is minimized.
In some embodiments, the target transmission power may be obtained according to respective corresponding currents when the radio frequency module performs data transmission using a plurality of different transmission powers, and respective corresponding transmission durations for transmitting a frame of data using the plurality of different transmission powers. The transmission duration may refer to a total time required to transmit one frame of data. Optionally, the sending duration may be related to factors such as sending power of the radio frequency module, signal strength of the mobile terminal, and data amount of one frame of data, where the data amount of one frame of data may be determined according to actually sent data, and optionally, the data amount of each frame of data may be different when different types of data are transmitted, for example, when different types of data such as image data, text data, and video data are transmitted, the data amount of each frame of data may be different. Further, the sending time duration and the sending power of the radio frequency module may be in a negative correlation relationship, the sending time duration and the signal strength of the mobile terminal may be in a negative correlation relationship, and the sending time duration and the data size of one frame of data may be in a positive correlation relationship. When the transmission power of the rf module is higher, the signal strength of the mobile terminal is stronger, and the data amount of one frame of data is smaller, the transmission duration may be shorter.
In one embodiment, the plurality of different transmit powers used by the radio frequency module may include a first transmit power, which may be any one of the plurality of different transmit powers. Taking the first sending power as an example, the first sending duration corresponding to the first sending power may be obtained according to the first sending power, the network signal strength when performing data transmission, and the data size of one frame of data. The terminal equipment can detect the network signal intensity, test the sending duration corresponding to the frame data sent by the radio frequency module by using a plurality of different sending powers under the network signal intensity, and establish the corresponding relation between the sending duration and the sending power according to the test result. Alternatively, the plurality of different transmit powers for the test transmit duration may be the same as the plurality of different transmit powers for the test current.
For example, in an embodiment, under the condition that the network signal strength of the terminal device is-80 dB (decibel) to-85 dB, the corresponding relationship between the transmission power and the transmission time duration used when the radio frequency module performs data transmission may be as shown in table 2.
TABLE 2
As can be seen from table 2, the larger the transmission power of the rf module is, the shorter the corresponding transmission duration is. In an embodiment, the target transmission power may be a transmission power with a minimum transmission total current among transmission total currents respectively corresponding to a plurality of different transmission powers, where the transmission total current corresponding to each transmission power may be directly detected when each transmission power transmits one frame of data, or may be obtained according to a current corresponding to each transmission power when each transmission power performs data transmission and a transmission duration for transmitting one frame of data.
Taking the first sending power included in the multiple different sending powers as an example, the first total transmission current corresponding to the first sending power may be obtained according to a first current corresponding to the first sending power when data transmission is performed by using the first sending power and the first sending duration, and further, the first total transmission current corresponding to the first sending power is a product of the first current corresponding to the first sending power when data transmission is performed by using the first sending power and the first sending duration. For example, taking the data in tables 1 and 2 as an example, the total transmission current of the rf module during data transmission using 17dBm is 300mA, 23ms, 6900mA, and the total transmission current of the rf module during data transmission using 23dBm is 580mA, 10ms, 5800mA, which are not listed here. And after the transmission total current corresponding to each transmission power is calculated one by one, the transmission power with the minimum transmission total current can be selected as the target transmission power.
In an embodiment, the target transmission power may be a minimum transmission power in a difference between a current corresponding to each of the plurality of different transmission powers used by the radio frequency module for data transmission and a corresponding average current, where the average current corresponding to each of the plurality of transmission powers may be a current consumed per unit time in a transmission duration corresponding to one frame of data transmitted by each of the plurality of transmission powers when the radio frequency module performs data transmission using a preset maximum transmission power. Taking the first transmission power included in the plurality of different transmission powers as an example, the average current corresponding to the first transmission power may refer to a current consumed by the radio frequency module per unit time in the first transmission duration when the radio frequency module performs data transmission using the preset maximum transmission power.
The terminal device may calculate a maximum total transmission current corresponding to data transmission using a preset maximum transmission power, where the maximum total transmission current may be a product of a current corresponding to data transmission using the preset maximum transmission power and a transmission time corresponding to transmission of one frame of data using the preset maximum transmission power. For example, taking the data in tables 1 and 2 as an example, if the preset maximum transmission power is 23dBm, the maximum total transmission current is 580mA, 10ms, 5800 mA. And then calculating the ratio of the maximum transmission total current to the sending time length corresponding to each sending power to obtain the average current corresponding to each sending power. Taking the first transmission power as an example, the average current corresponding to the first transmission power may be a ratio of the maximum transmission current to a first transmission duration corresponding to transmitting one frame of data by using the first transmission power.
For example, taking the data in tables 1 and 2 as an example, where the preset maximum transmission power is 23dBm, the average current corresponding to each transmission power can be obtained as shown in table 3.
TABLE 3
| Radio frequency module transmission power | Electric current | Sending duration | Average current |
| 17dBm | 300mA | 23ms | 580*10/23＝252mA/ms |
| 18dBm | 330mA | 18ms | 580*10/18＝322mA/ms |
| 19dBm | 350mA | 15ms | 580*10/15＝387mA/ms |
| 20dBm | 400mA | 13ms | 580*10/13＝446mA/ms |
| 21dBm | 460mA | 12ms | 580*10/12＝483mA/ms |
| 22dBm | 560mA | 10ms | 580*10/10＝580mA/ms |
| 23dBm | 580mA | 10ms | 580*10/10＝580mA/ms |
And calculating the difference between the corresponding current and the corresponding average current when each sending power carries out data transmission, and selecting the sending power with the minimum difference as the target sending power. Taking the first sending power as an example, the difference corresponding to the first sending power may be a difference obtained by subtracting the corresponding first average current from the corresponding first current when the first sending power performs data transmission. Taking the data in table 3 as an example, the difference between the corresponding current and the corresponding average current when data transmission is performed at each transmission power can be shown in table 4.
TABLE 4
The current corresponding to the target sending power when data transmission is performed needs to be smaller than the average current corresponding to the target sending power, so that the sending power of which the current corresponding to the data transmission is smaller than the corresponding average current can be selected from the current corresponding to the data transmission and the corresponding average current in the plurality of sending powers, and the sending power of which the absolute value of the difference value between the current corresponding to the data transmission and the corresponding average current is the maximum is determined as the target sending power in the sending power of which the current corresponding to the data transmission is smaller than the corresponding average current. For example, taking the data in table 4 as an example, among the plurality of different transmission powers in table 4, the transmission power at which the current corresponding to the data transmission is smaller than the corresponding average current includes 19dBm, 20dBm, 21dBm, and 22dBm, where the transmission power at which the absolute value of the difference between the current corresponding to the data transmission and the corresponding average current is the largest is 20dBm, that is, 46mA, it is determined that 20dBm is the target transmission power, and the difference-46 mA corresponding to the transmission power of 20dBm is also the smallest difference in table 4.
And step 220, performing data transmission by taking the target transmission power as the maximum transmission power.
The radio frequency module of the terminal equipment can acquire the maximum target sending power and send data to the network equipment, the maximum sending power of the radio frequency module can be adjusted to be the target sending power, and the sending power of the radio frequency module can be smaller than or equal to the target sending power during data transmission, so that the power consumption of the radio frequency module during data transmission can be reduced.
In the embodiment of the application, the target transmission power of the radio frequency module is obtained according to the currents corresponding to the radio frequency module when the radio frequency module uses a plurality of different transmission powers to perform data transmission, the target transmission power is smaller than the preset maximum transmission power of the radio frequency module, then the obtained target transmission power is used as the maximum transmission power to perform data transmission, the radio frequency module can perform data transmission with reasonable transmission power, the current during data transmission is reduced, and therefore the power consumption of the radio frequency module during data transmission is reduced.
As shown in fig. 3, in one embodiment, another data transmission method is provided, which can be applied to the terminal device described above. The data transmission method may include the steps of:
The data transmission method provided by the embodiment of the application can be applied to the data transmission process during video call.
When the terminal device detects that the video call is entered, the statistical calculation of the corresponding sending power of the radio frequency module at each sending time for sending data can be started. In one embodiment, the sending time may be determined according to a transmission frame rate of the rf module during data transmission, where the transmission frame rate may refer to a transmission speed of the data transmission, and for example, the transmission frame rate may be 10 frames/s (seconds), 30 frames/s, 45 frames/s, or the like. The transmission time intervals corresponding to different transmission frame rates may be different, and a transmission time interval may refer to a time interval between two frames of data, for example, the transmission frame rate is 10 frames/s, the corresponding transmission time interval is 100ms, that is, the rf module may send one frame of data to the network device every 100ms, the transmission frame rate is 20 frames/s, and the corresponding transmission time interval is 50ms, that is, the rf module may send one frame of data to the network device every 50 ms. The sending time is the time when the radio frequency module sends data to the network device each time. After entering the video call, the corresponding sending power of the radio frequency module when sending data at each sending moment can be obtained.
When the terminal equipment is in a video call state, whether the target ratio is greater than a ratio threshold value or not can be judged. The target occupation ratio may refer to an occupation ratio in which the transmission power at different transmission moments within a preset time period is greater than a power threshold.
In the video call process, the sending powers respectively corresponding to the radio frequency module sending data at different sending times within a preset time period may be obtained, where the preset time period may be set according to a requirement, for example, may be 1 second, 2 seconds, 5 seconds, and the like, and is not limited herein. The ratio of the transmission power to the transmission power which is greater than the power threshold value in the transmission power respectively corresponding to the data transmission at different transmission moments in the preset time period can be calculated. The target ratio may be a ratio between the number of transmission times corresponding to the transmission time greater than the power threshold and the number of all transmission times within a preset time period. For example, the preset time period is 1 second, the transmission frame rate when the radio frequency module transmits data is 10 frames/second, then 1 second includes 10 transmission times, wherein the transmission power corresponding to 1 transmission time is greater than the power threshold value 20dBm, and then the target occupancy is 10%.
When the target ratio is greater than the ratio threshold, it can be said that the probability that the radio frequency module uses a larger transmission power to perform data transmission is larger, the target transmission power of the radio frequency module can be obtained, and the maximum transmission power of the radio frequency module is adjusted to a reasonable target transmission power, so as to reduce the power consumption of data transmission in the video call process of the terminal device. Alternatively, the proportional threshold may be set according to actual requirements, such as 5%, 8%, etc., and is not limited herein.
If the target ratio is less than or equal to the ratio threshold, whether the video call is ended or not can be judged, if the video call is not ended, the corresponding sending power of the radio frequency module when sending data at each sending time can be continuously obtained, and whether the ratio (namely the target ratio) of the sending power at different sending times in the preset time period which is greater than the power threshold is greater than the ratio threshold or not is judged.
And under the condition that the target ratio is larger than the ratio threshold, acquiring the target transmission power of the radio frequency module. In an embodiment, before obtaining the target transmission power of the radio frequency module, it may be determined whether the network signal strength of the terminal device is within a preset signal strength range, and if the network signal strength of the terminal device is within the preset signal strength range, the target transmission power of the radio frequency module is obtained. When the network signal intensity of the terminal device is not within the preset signal intensity range, it can be stated that the current network signal of the terminal device is poor, and if the maximum transmission power of the radio frequency module is adjusted, a large time delay is generated, which results in a video call being stuck. Therefore, when the network signal intensity of the terminal equipment is within the preset signal intensity range, the target sending power of the radio frequency module is obtained, and the video call quality can be guaranteed while the power consumption is reduced.
In some embodiments, the target transmission power may be obtained according to a current respectively corresponding to the radio frequency module when performing data transmission using a plurality of different transmission powers, a transmission duration respectively corresponding to a frame of data transmitted using the plurality of different transmission powers, and a transmission frame rate. The transmission frame rate of the radio frequency module for data transmission is independent of the used transmission power, and can be related to the required data quality during data transmission. For example, the transmission frame rate of the rf module during data transmission may be related to video definition, smoothness, and the like required in the video call process, and the higher the video definition is, the higher the corresponding transmission frame rate may be.
The transmission time length corresponding to the target transmission power used by the radio frequency module to transmit one frame of data needs to be less than the transmission time interval corresponding to the transmission frame rate. After the terminal device calculates the sending time length corresponding to each sending power sending a frame of data according to each sending power, the network signal strength during data transmission and the data volume of the frame of data, which are made by the radio frequency module, it can be judged one by one whether the sending time length corresponding to each sending power is smaller than the transmission time interval corresponding to the transmission frame rate, the sending power of the sending time length for sending the frame of data smaller than the transmission time interval corresponding to the transmission frame rate is used as the pre-selection sending power, and then the target sending power is selected from one or more pre-selection sending powers. Optionally, the manner of selecting the target transmission power may refer to various manners described in step 210 in the foregoing embodiments, and details are not repeated herein. The sending time length corresponding to the target sending power sending one frame of data is smaller than the transmission time interval corresponding to the transmission frame rate, so that the video call quality in the video call process can be ensured, and the power consumption can be effectively reduced.
Taking the data in tables 2 to 4 as an example, assuming that the transmission frame rate when the radio frequency module transmits data is 50 frames/s, the transmission time interval corresponding to the transmission frame rate is 20ms, and the radio frequency module transmits data to the network device once every 20 ms. After the test radio frequency module uses a plurality of different transmission powers to transmit the time length of one frame of data, whether the transmission time length corresponding to each transmission power is less than 20ms or not can be judged, and as shown in the data shown in table 2, the transmission time lengths corresponding to 6 transmission powers of 18 dBm-23 dBm are less than 20ms respectively, then the 6 transmission powers of 18 dBm-23 dBm can be used as pre-selection transmission powers, and then the target transmission power is selected from the pre-selection transmission powers.
And step 306, performing data transmission with the target transmission power as the maximum transmission power.
