Description

Power control method and electronic device

technical field

Embodiments of the present invention relate to the field of communication technologies, and in particular, to a power control method and an electronic device.

Background technique

The uplink power of the electronic device is the power used by the electronic device to transmit signals. Generally speaking, the uplink power will be limited within the maximum value due to factors such as the transmission capability of the radio frequency device of the electronic device and the mutual radiation interference in the mobile network environment. The maximum value is generally related to the following parameters:

1. The maximum uplink power of the electronic device configured by the network, for example, the p-Max parameter configured in the system message 1 of the long-term evolution technology LTE system; the P-NR parameter in the system message 1 of the new air interface NR system. The maximum uplink power configured by the network is used to ensure that the electronic device can effectively send signals, and on the other hand, it is used to reduce the uplink interference between different electronic devices;

2. The maximum power (capability) of the radio frequency RF device (PA) of the electronic equipment in the steady state. If the actual power of the electronic device exceeds this maximum capability, the RF device may have problems such as unstable device output power, accelerated aging, and increased power consumption.

The final maximum uplink power may be the union of these two parameters, that is, the minimum value of the two parameters is taken as the maximum value of the uplink power that can be achieved by the electronic device.

In the prior art, the power level configured at each network end corresponds to a default power, and the electronic device can only use the default power to transmit uplink signals. In this case, the electronic device lacks flexibility and cannot adjust the transmit power according to the network transmission conditions or the power of the electronic device itself.

Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

【network system】

As shown in FIG. 1 , in the network system, the electronic devices 111 and 112 are connected to the base station 120 through a radio frequency link. The direction in which the signals are transmitted from the base station 120 to the electronic devices 111 and 112 is the downward direction, and the direction in which the signals are transmitted from the electronic devices 111 and 112 to the base station 120 is the upward direction. The base station 120 is connected to switches 130, 140 in the communication backbone, and through the switches 130, 140 to an external network 150, such as the Internet.

As shown in FIG. 1 , in the uplink direction, there is an uplink from the electronic device 111 to the base station 120 and an uplink from the electronic device 112 to the base station 120 . If the signals are transmitted simultaneously in the two uplinks, there will be interference between the two uplinks. For example, to avoid excessive interference, the network end sends control information to the electronic devices 111 and 112 through the base station to control the power level of each electronic device. The control information is, for example, the p-Max parameter configured in the system message 1 of the long-term evolution technology LTE system; the P-NR parameter in the system message 1 of the new air interface NR system, and the like.

As shown in FIG. 1 , the electronic device 111 is farther from the base station 120 than the electronic device 112 . Therefore, the network can set a higher power level for the electronic device 111 .

Due to the differences in the radio frequency components of different electronic devices, for each power level, the base station can tolerate a certain range of deviation, for example, +2/-3dBm, that is, each power level corresponds to a power range, and the network side can allow this Uplink signals within the power range.

In a mobile communication network, under normal circumstances, the maximum uplink power P-MAX=23dBm is configured for an electronic device. However, at present, many electronic devices are high-power user equipment HPUE, and the maximum transmit power of the radio frequency RF device of this electronic device can reach 26 dBm power (HPUE, PC2). Therefore, this electronic device has a maximum transmit power of 3dBm which is limited by the network side.

The inventors found that in a weak field environment, problems such as high delay in games, network freezes, inability to access the Internet, call failure or unclear calls may occur. This may be due to poor uplink signal quality of the electronic device. For example, in this case, there will be many packet retransmissions in the uplink. This situation can be improved by increasing the uplink power of the electronic equipment. However, the configuration on the network side limits the performance of the electronic device.

After the electronic device receives the power level configured by the network, the electronic device uses the default uplink power or nominal power corresponding to the power level to transmit the uplink signal. Typically, the nominal power is the power in the middle of the power range for the corresponding power class.

On the other hand, if the electronic device transmits the uplink signal at high power, this consumes the power of the electronic device, reducing the usage time of the electronic device, and also may have an impact on the battery life of the electronic device.

[Method embodiment]

FIG. 2 shows a schematic flowchart of a power control method according to an embodiment.

As shown in FIG. 2, in step S12, the uplink power level configured by the network is obtained. For example, the uplink power level of the electronic device can be configured through the p-Max parameter configured in the system message 1 of the long-term evolution technology LTE system; the P-NR parameter in the system message 1 of the new air interface NR system, etc.

In step S14, the adjusted uplink power is determined according to the network transmission condition determined by the electronic device, wherein the adjusted uplink power is within the power range determined by the uplink power level and is different from the nominal uplink power level power. The network transmission status may be, for example, the signal strength status of the current network, or the status of the electronic device currently using the network for transmission, and so on. Nominal power is the standard power value of the corresponding power level. For example, the standard power value corresponding to power level 2 (PC2) in mobile communication is 26dBm, and the allowable error range of PC2 is +-2dBm. Therefore, the power range corresponding to PC2 is 24-28dBm. In general, the uplink power (ie, the nominal power) determined by the electronic device should be 26dBm. Here, according to the network transmission conditions, the adjusted uplink power may be a value greater than 26dBm or a value less than 26dBm, so as to meet the requirements of transmission performance and/or power consumption of mobile phones according to different situations.

In step S16, the uplink signal is transmitted using the adjusted uplink power.

In this way, on the one hand, the adjusted uplink power complies with the requirements of the uplink power level configured by the network end, so it will not cause a great impact on the current mobile network. On the other hand, by adjusting the uplink power, the communication quality of the electronic device can be improved and/or the power of the electronic device can be saved. Through the solution here, a flexible way can be provided, which can improve the ratio between improving the quality of the uplink communication and improving the performance of the electronic device by adjusting the uplink power while minimizing the impact on the mobile network. good balance.

In the first embodiment, under the condition that the network transmission condition satisfies the first predetermined condition, the adjusted uplink power may be gradually increased from the nominal power by a predetermined adjustment range below the upper limit of the power range. The designer of the electronic device can set the first predetermined condition as required, for example, the signal strength detected by the electronic device is less than a predetermined value and the like. For example, the predetermined adjustment amplitude may be 0.1 dBm, or other predetermined values. In many cases, it is difficult to determine the magnitude of the power increase required. Here, it is only necessary to set the adjustment purpose that needs to be achieved, and the uplink power in the electronic device can automatically approach the target value, so as to achieve the effect of automatic adjustment, and the complicated calculation process can be omitted.

The adjusted upstream power may be an increased upstream power relative to the nominal power. The uplink power can be gradually increased by the above step-by-step method, or the uplink power value can be calculated by the computing unit in the electronic device based on the network transmission condition. When the network transmission condition satisfies a first predetermined condition, an uplink signal is transmitted using the increased uplink power.

With the development of technology, the implementation of electronic devices is becoming more and more flexible. The above-mentioned processing can be implemented by dedicated hardware, or can be implemented by a processor such as a central processing unit in a manner of software execution. Then, the processing result is transmitted to the radio frequency antenna unit as a transmitter through an electrical signal. The electrical signal includes the data signal to be transmitted and the uplink power required for transmission. The radio frequency antenna unit amplifies the data signal according to the set uplink power, and sends it to the corresponding base station through the antenna.

The electronic device can use the existing parameters in the mobile communication system to judge the network transmission status and/or set the first predetermined condition, so that the additional processing of the electronic device can be omitted, and the extra overhead generated by the electronic device to implement the solution herein can be reduced. For example, the first predetermined condition includes at least one of the following conditions:

- The uplink retransmission rate of the physical layer (layer 1 or L1) channel is higher than the preset retransmission rate threshold. This indicates that the base station does not normally receive the data packets sent by the electronic device. Therefore, the wireless connection between the electronic device and the base station can be strengthened by increasing the uplink power. For example, an example value for the retransmission rate threshold value is 60%.

- The uplink power level configured by the network is the highest uplink power level and the duration of the highest uplink power level exceeds a preset first time threshold. This shows that the network side judged that the quality of the connection with the electronic device was poor and has been trying to instruct the electronic device to transmit at the highest uplink power to strengthen the wireless connection.

- The maximum transmit power of the radio frequency device of the electronic device is greater than or equal to the adjusted uplink power.

- the duration of the electronic device in the state where the screen is lit exceeds the second time threshold. This shows that the current user has been using the electronic device. Therefore, in this case, increasing the uplink power, thereby improving the network transmission performance, can give the user a better experience.

- The electronic device detects that the user's continuous operation duration exceeds the third time threshold value. Similar to the reasons described above, in this case, increasing the uplink power, thereby improving the network transmission performance, can give the user a better experience.

- the duration that the uplink of the electronic device is in the continuous transmission state exceeds the fourth time threshold value. This is also similar to the situation described above. In this case, increasing the uplink power, thereby improving the network transmission performance, can give users a better experience.

- An application running in the electronic device requires an uplink latency lower than the first predetermined latency and/or an uplink throughput higher than the first predetermined throughput. For example, the user is using the electronic device for games, voice calls, uploading data, etc. In this case, increasing the uplink power, thereby improving the network transmission performance, can give users a better experience.

The above-mentioned first to fourth time thresholds, the first predetermined time delay and the second predetermined time delay may be empirical values. The designer of the electronic device can set the above-mentioned values based on the statistics of the user's use of the electronic device. For example, the first time threshold may be 1 minute, the second to fourth time thresholds may be 5 minutes respectively (they may also be different values), the first predetermined delay is 1 millisecond, and the first predetermined Throughput 1Mbits/s.

In addition, it can also take into account the network transmission performance and battery power requirements of electronic devices.

For example, when it is determined according to the network transmission condition that the electronic device is in a strong signal environment and the power of the electronic device is greater than the first power threshold value, the uplink signal is transmitted using the increased uplink power. When the reference signal received power RSRP received by the electronic device is greater than -113dBm, the electronic device determines that the network transmission condition is in a strong signal environment, and the first power threshold may be 70% of the battery power of the electronic device.

For example, when it is determined according to the network transmission condition that the electronic device is in a weak signal environment and the power of the electronic device is greater than the second power threshold value, the uplink signal is transmitted using the increased uplink power. When the reference signal received power RSRP received by the electronic device is less than or equal to -113dBm, the electronic device determines that the network transmission condition is in a weak signal environment, and the second power threshold may be 30% of the battery power of the electronic device.

Here, the strong signal environment is relative to the weak signal environment. The signal strength in a strong signal environment is greater than that in a weak signal environment. Although here, as an example, a strong signal environment and a weak signal environment are distinguished by taking -113dBm as an example, those skilled in the art should understand that on the premise that the signal strength in a strong signal environment is greater than that in a weak signal environment , the designer can define the strong signal environment and the weak signal environment as needed. For example, the RSRP in the strong signal environment is greater than -110dBm, and the RSRP in the weak signal environment is less than or equal to -113dBm.

Here, the second power threshold value is smaller than the first power threshold limit. This is because, in a weak signal environment, users have more requirements for transmission performance.

The electronic device can also recover from the state of increasing the uplink power to the state of the nominal power. For example, when at least one of the following conditions is met, the electronic device exits the above state:

- The uplink power level configured on the network side is a lower uplink power level lower than the highest uplink power level and the duration of the lower uplink power level exceeds a predetermined time. In this case, the electronic device enters the network coverage area with better signal, so there is no need to increase the uplink power.

- In a weak signal environment, the battery level of the electronic device is less than 30%. At this time, in order to ensure the standby time of the electronic device, the uplink power is reduced to save power.

- In a strong signal environment, the battery level of the electronic device is less than 70%. In this case, appropriately reducing the uplink power will not have a significant impact on the communication of the user, and at the same time, the standby time of the electronic device can be prolonged.

- When the uplink power is increased, the communication quality of the electronic device does not improve, or there is a situation where it is not necessary to increase the uplink power. For example, due to an abnormality in the operator or server, the upper-layer software of the electronic device detects that the user's usage scenario has not improved, for example, the game delay is still high or the voice packet loss rate of IP calls is still high. For example, the electronic device goes into a screen-off state, or the user exits a demanding application.

In another embodiment, when the network transmission condition satisfies the second predetermined condition, the adjusted uplink power is gradually reduced by a predetermined adjustment range. The designer of the electronic device can set the second predetermined condition as required, for example, the signal strength detected by the electronic device is greater than a predetermined value, and the like. For example, the predetermined adjustment amplitude may be 0.1 dBm, or other predetermined values. By reducing the uplink power under the condition that the second predetermined condition is met, the power consumed by the electronic device can be reduced under the condition that the transmission performance requirement is met. In this way, the use time of the electronic device after each charge can be extended, and the life of the battery can also be extended. In addition, similar to the above description about the increased uplink power, this step-by-step adjustment method can achieve the effect of automatic adjustment, and can save the complicated calculation process.

The adjusted uplink power may be a reduced uplink power relative to the nominal power. The uplink power may be gradually reduced in the above-mentioned step-by-step manner, or the uplink power value may be calculated by the computing unit in the electronic device based on the network transmission status. The uplink signal is transmitted using the increased uplink power if the network transmission condition satisfies a second predetermined condition.

The electronic device can use the existing parameters in the mobile communication system to judge the network transmission status and/or set the second predetermined condition, so that the additional processing of the electronic device can be omitted, and the extra overhead generated by the electronic device to realize the solution here is reduced. For example, the second predetermined condition includes at least one of the following conditions:

- The uplink power level configured by the network is a lower uplink power level lower than the highest uplink power level and the duration of the lower uplink power level exceeds a preset fifth time threshold. The lower upstream power level may be the lowest upstream power level. This shows that the current network conditions are good, and the lower uplink power can also meet the communication requirements. In this case, appropriately reducing the uplink power will not have much impact on the transmission, however, it can save the power of the electronic equipment, thus prolonging the battery life and life.

- the electronic device exceeds the sixth time threshold value in a state where the screen is turned off. This indicates that the user has not used the electronic device for the time being. In this case, only the minimum connection requirements need to be guaranteed, and there will be no impact on the user's use. In this case, appropriately reducing the uplink power can save the power of the electronic equipment, thereby prolonging the battery life and life.

- The electronic device can allow uplink latency higher than the second predetermined latency and/or uplink throughput lower than the second predetermined throughput. For example, a user sends a text message using an electronic device. In this application scenario, the degradation of transmission performance caused by appropriately reducing the uplink power will not affect the usage of users. Likewise, this approach saves power in electronic devices, thereby extending battery life and life.

In addition, the timing of using the reduced uplink power can also be determined in consideration of the power and the signal environment.

For example, when it is determined according to the network transmission condition that the electronic device is in a strong signal environment and the power of the electronic device is less than the third power threshold value, the uplink signal is transmitted using the reduced uplink power. For example, when the reference signal received power RSRP received by the electronic device is greater than -113dBm, the electronic device determines that the network transmission condition is in a strong signal environment, and the third power threshold is 70% of the battery power of the electronic device.

For example, when it is determined according to the network transmission condition that the electronic device is in a weak signal environment and the power of the electronic device is less than the fourth power threshold value, the uplink signal is transmitted using the reduced uplink power. For example, when the reference signal received power RSRP received by the electronic device is less than or equal to -113dBm, the electronic device determines that the network transmission condition is in a weak signal environment, and the second power threshold is 30% of the battery power of the electronic device.
