Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application.
The uplink transmitting power control method provided by the application can be applied to an application environment shown in fig. 1. Wherein the terminal 102 communicates with the network device 104 via a network. The terminal 102 may be, but not limited to, various personal computers, notebook computers, smart phones, tablet computers, and portable wearable devices, and the network device 104 may be, but not limited to, a base station.
Specifically, the terminal 102 accesses the network and reports the upper limit value of the uplink transmission power to the network device 104. After receiving the upper limit value of the uplink transmission power, the network device 104 detects the upper limit value of the uplink transmission power, and generates power configuration information, where the power configuration information includes a power control parameter and a network device power parameter. The terminal 102 receives the power configuration information sent by the network device 104, and obtains a power control parameter and a network device power parameter. The terminal 102 obtains the signal strength, adjusts the power control parameter according to the signal strength, and obtains an updated power control parameter. Further, the terminal 102 obtains a terminal power parameter, and calculates the terminal power parameter, the updated power control parameter and the network device power parameter to obtain uplink transmission power.
In one embodiment, as shown in fig. 2, there is provided an uplink transmission power control method, which is illustrated by taking an example that the method is applied to the terminal in fig. 1, and includes the following steps:
step 202, accessing the network, reporting the upper limit value of the uplink transmission power to the network device, so that the network device generates power configuration information according to the upper limit value of the uplink transmission power, wherein the power configuration information comprises a power control parameter and a network device parameter.
Where network devices refer to devices connected to a network system, including but not limited to base stations. The upper limit value of the uplink transmission power refers to the maximum uplink transmission power of the terminal. The power configuration information includes parameters related to uplink transmit power configured by the network device, such as power control parameters and network device parameters.
Specifically, when the terminal accesses to a wireless network, for example, a GPRS (General packet radio service ) network, the terminal reports an upper limit value of uplink transmission power to the network device. When the uplink transmission power is too high, the communication module of the terminal is always under high transmission power, so that the electric quantity consumption of the communication module is seriously affected, the power consumption is wasted, and even the communication of other terminals can be affected. When the uplink transmission power is too small, the communication quality between the terminal and the network equipment is affected, and even the terminal is dropped. Therefore, after receiving the upper limit value of the uplink transmission power reported by the terminal, the network device needs to detect the upper limit value of the uplink transmission power, generate corresponding power configuration information, and send the power configuration information to the terminal, so that the terminal can adjust the uplink transmission power according to the power configuration information.
And step 204, receiving the power configuration information to obtain the power control parameter and the network equipment power parameter.
The power control parameter is a variable issued by the network equipment, and the value range of the power control parameter is between 0 and 62 dB. The network device power parameter is a maximum transmission power that the network device is allowed to output, and is kept unchanged in the case that the terminal does not switch the connected network device.
Specifically, when the network device receives the upper limit value of the uplink transmission power, the upper limit value of the uplink transmission power is detected, and the radio frequency capability of the terminal is known. The network device generates power configuration information according to the radio frequency capability of the terminal and sends the power configuration information to the terminal. The power configuration information not only includes the power control parameters and the maximum transmit power that the network device is allowed to output, but also carries system parameters. Wherein both the power control parameters and the system parameters are variables.
Step 206, obtaining the signal intensity, and adjusting the power control parameter according to the signal intensity to obtain the updated power control parameter.
Wherein the updated power control parameter is the adjusted power control parameter. The signal strength is a reception level detected by the terminal and is used to indicate the current communication quality.
Specifically, after receiving the power adjustment instruction, the terminal adjusts the power control parameter. As is known from the 3GPP protocol, the larger the power control parameter is, the smaller the uplink transmission power is, and the smaller the power control parameter is, the larger the uplink transmission power is. In order to ensure that the terminal can smoothly communicate with the network device and reduce power consumption, the terminal may adjust the power control parameter according to the signal strength.
When the signal strength is greater than the preset signal strength, the terminal can obtain uplink transmission power by increasing the power control parameter, so that the output of the uplink transmission power is reduced, and the power consumption is reduced. Conversely, when the signal strength is smaller than the preset signal strength, the terminal can enhance the output of the uplink transmitting power by reducing the power control parameter, so as to realize the communication between the terminal and the network equipment.
Step 208, obtaining the terminal power parameter, and calculating the terminal power parameter, the updated power control parameter and the network device power parameter to obtain the uplink transmitting power.
The terminal power parameter refers to a power parameter of a terminal specified in a 3GPP protocol. For the GSM850 and GSM900 frequency bands, the terminal power parameter is 39dB; the terminal power parameter is 36dB for DCS1800 and PCS1900 bands.
Specifically, the terminal calculates a terminal power parameter, an updated power control parameter and a network device power parameter based on subtraction operation and minimum function operation to obtain uplink transmission power, and communicates with the network device by using the uplink transmission power.
In the uplink transmission power control method, the upper limit value of the uplink transmission power is reported to the network equipment through the access network, so that the network equipment generates power configuration information according to the upper limit value of the uplink transmission power, wherein the power configuration information comprises power control parameters and network equipment parameters; receiving power configuration information to obtain a power control parameter and a network equipment power parameter; acquiring signal intensity, and adjusting the power control parameter according to the signal intensity to obtain an updated power control parameter; the method comprises the steps of obtaining a terminal power parameter, calculating the terminal power parameter, an updated power control parameter and a network equipment power parameter to obtain uplink transmitting power, wherein the uplink transmitting power is different from the uplink transmitting power obtained by calculating the terminal power parameter, the power control parameter, a system parameter, a receiving level and the network equipment power parameter in the traditional method.
In one embodiment, step 206 includes: adjusting the power control level of the power control parameter according to the signal strength; and taking the value corresponding to the adjusted power control level as an updated power control parameter.
Wherein the power control parameter occupies 5bit data bit length, and can represent the range of 0-31. The power control levels are 0-31 levels, each level being incremented by 2dB steps. For example, when the power control level is 3, the corresponding power control parameter is 6dB, and when the power control level is 5, the corresponding power control parameter is 10dB. Wherein the power control level 0 is the highest level and the power control level 31 is the lowest level.
Specifically, when the signal strength is greater than the preset signal strength, the terminal can increase the power control parameter by reducing the power control level, thereby obtaining the uplink transmission power, reducing the output of the uplink transmission power and reducing the power consumption. Conversely, when the signal strength is smaller than the preset signal strength, the terminal can reduce the power control parameter by increasing the power control level, enhance the output of the uplink transmitting power, and ensure the effective communication between the terminal and the network equipment.
In this embodiment, the terminal adjusts the power control parameter by detecting the obtained signal strength, so that the power consumption of the terminal communication module can be reduced when the signal strength is strong, and the output of the uplink transmitting power can be enhanced when the signal strength is weak, so as to ensure the effective communication between the terminal and the network device.
In one embodiment, step 208 includes: calculating to obtain a difference value between the terminal power parameter and the updated power control parameter; comparing the difference with the power parameter of the network equipment to obtain a comparison result; and determining the uplink transmitting power according to the comparison result.
Specifically, the difference is obtained by subtracting the updated power control parameter from the terminal power parameter, that is, subtracting the updated power control parameter from the maximum uplink transmit power of the terminal. Based on the minimum function, the difference is compared with the network device power parameters to obtain the smaller of the difference and the network device power parameters.
In one embodiment, when the difference is smaller than the network device power parameter, the difference is taken as the uplink transmission power; and when the difference is greater than or equal to the network device power parameter, taking the network device power parameter as uplink transmitting power.
Specifically, the uplink transmit power may be calculated by the following formula:
P CH ＝min[Γ 0 -Γ CH ,PMAX]
wherein P is CH Representing uplink transmit power Γ 0 Representing terminal power parameters Γ CH Representing updated power control parameters, PMAX represents network device power parameters.
In this embodiment, the minimum value between the difference value between the terminal power parameter and the update power control parameter and the network device power parameter is used as the uplink transmission power, so that the calculation process is simple, and the control of the terminal on the uplink transmission power is facilitated.
In one embodiment, when the uplink transmission power is smaller than a preset threshold value, the power compensation is performed on the uplink transmission power through a power amplifier.
The power amplifier is connected with a communication module of the terminal and is used for performing power compensation on uplink transmitting power.
Specifically, when the uplink transmission power is smaller than the preset threshold, the terminal can perform power compensation on the uplink transmission power output by the communication module through the power amplifier, and the terminal communicates with the network equipment according to the uplink transmission power after power compensation, so that effective communication between the terminal and the network equipment can be ensured, and the power consumption of the communication module can be reduced.
In one embodiment, adjusting the power control parameter based on the signal strength, the obtaining updated power control parameter includes: reducing the power control level of the power control parameter; and taking the value corresponding to the reduced power control level as an updated power control parameter.
Specifically, when the communication module of the terminal is connected with the power amplifier, and uplink transmission power is compensated by the power amplifier, the terminal may directly reduce the power control level of the power control parameter without considering the influence of signal strength on updating the power control parameter, and take the value corresponding to the reduced power control level as the power control parameter.
Further, for example, in the conventional method, the calculation formula of the uplink transmit power is as follows:
P CH ＝min[Γ 0 -Γ CH -α(C+48),PMAX]
wherein P is CH Representing uplink transmit power Γ 0 Representing terminal power parameters Γ CH Representing power control parameters, α representing system parameters, C representing reception levels, PMAX representing network device power parameters.
As shown in fig. 3, under the GSM900 network, the terminal power parameter is 39dBm. When the system parameter issued by the network equipment is 7, the terminal can calculate that the uplink transmitting power is 15dB when the receiving level is-40 dBm and the power control parameter is 24 dB; when the receiving level is-75 dBm and the power control parameter is 24dB, the terminal can calculate that the uplink transmitting power is 33dB.
As shown in fig. 4, also in the GSM900 network, the terminal power parameter is 39dBm. When the system parameter issued by the network device is 7, the system parameter is set to 0 because the system parameter is not considered when the uplink transmission power is calculated. When the system parameter α is 0, the value of α (c+48) is also 0. The terminal can calculate that the uplink transmission power is 15dB, whether the reception level is-40 dBm, the updated power control parameter is 24dB, or the reception level is-75 dBm, and the updated power control parameter is 24 dB.
Compared with the prior art, the calculation process is simpler, the control of the terminal on the uplink transmitting power is facilitated, and the power consumption of the communication module can be reduced.
In this embodiment, the power amplifier compensates the uplink transmission power, so that the power consumption of the communication module can be reduced while ensuring effective communication between the terminal and the network device.
In one embodiment, as shown in fig. 5, another uplink transmission power control method is provided, and the method is applied to the terminal in fig. 1 for illustration, and includes the following steps:
step 502, accessing the network, reporting the upper limit value of the uplink transmission power to the network equipment, so that the network equipment generates power configuration information according to the upper limit value of the uplink transmission power, wherein the power configuration information comprises a power control parameter and a network equipment parameter;
step 504, receiving power configuration information to obtain power control parameters and network equipment power parameters;
step 506, reducing the power control level of the power control parameter;
step 508, taking the value corresponding to the reduced power control level as an updated power control parameter;
step 510, obtaining a terminal power parameter, and calculating to obtain a difference between the terminal power parameter and an updated power control parameter;
step 512, comparing the difference value with the network device power parameter;
step 514, when the difference is smaller than the power parameter of the network device, the difference is used as the uplink transmission power;
step 516, when the difference is greater than or equal to the network device power parameter, using the network device power parameter as the uplink transmission power;
and 518, when the uplink transmission power is smaller than the preset threshold value, performing power compensation on the uplink transmission power through a power amplifier.
In this embodiment, by setting the system parameter issued by the network device configuration to 0, when calculating the uplink transmission power, the influence of the system parameter and the reception level is eliminated, the calculation process is simplified, and by reducing the power control level, the uplink transmission power is reduced, and then the uplink transmission power is compensated by the power amplifier, so that the effective communication between the terminal and the network device is ensured, and meanwhile, the power consumption of the communication module of the terminal is reduced.
