A kind of power regulating method provided by the embodiments of the present application is applied in communication system as shown in Figure 1.It is described logical
Letter system 100 includes base station 101 and multiple terminals 102.Pass through wireless signal transmission number between the base station 101 and terminal 102
According to.
The embodiment of the present application provides a kind of power regulating method, applied in communication system as shown in Figure 1.The side
Method can be executed by above-mentioned base station.The base station can the embodiment of the present application will below for LTE base station, the base station 4G, the base station 5G etc.
It carries out believing explanation so that the base station is the base station 5G as an example.As shown in Fig. 2, the method includes S201-S205:
S201, the SINR value for obtaining the multiple terminal.
Wherein, the SINR value be the intensity of useful signal that receives of terminal with receive interference signal (noise and
Interference) intensity ratio.SINR=S/ (I+N)=RSRP/ (RSSI-RSRP).Wherein, the reception power of S GC group connector, one
As can with Reference Signal Received Power (Reference Signal Receiving Power, RSRP) indicate；Received letter
Number intensity instruction (Received Signal Strength Indication, RSSI) I+N is the sum of interference and noise, including
Non-service cell, adjacent-channel interference and internal system thermal noise power etc..
Specifically, indicating (Channel Quality using reference channel and Traffic Channel quality in 5G network
Indicator, CQI) this 2 kinds of SINR of SINR describe the intensity of signal.Wherein, because of the demodulation of CQI-SINR and user data
It is directly related, it is very big with user data rate correlation, so mainly considering that CQI-SINR is corresponding with power in this application
Relationship, the SINR being previously mentioned in the content below the embodiment of the present application are CQI-SINR.
Since 5G network is not yet formally disposed, which kind of mode to obtain the SINR of terminal using in following 5G commercial process
It is worth also indefinite.Therefore it is listed below the mode of two kinds of acquisition terminal SINR values, this two kinds acquisition terminal SINR in this step
The mode of value but should not be understood as the restriction to terminal SINR value mode is obtained only to facilitate better illustrate to scheme.
In practice, this step can take the mode of acquisition terminal SINR value known to anyone skilled in the art.
Mode one directly acquires terminal feedback SINR value.Specifically, 5G terminal may in following 5G commercial network
Has the function of directly reporting SINR value.Therefore base station can be spaced the SINR value that regular time obtains each terminal.
Mode two obtains SINR value by CQI.Specifically, obtaining the channel quality indicator (CQI) value of each terminal；According to
The CQI value and preset formula of each terminal calculate the SINR value of each terminal.
In existing 4G network, the relationship between CQI and SINR meets following formula:
SINR=a*CQI+b (1)
Wherein, a is gradient parameter, value 4；B is intercept parameter, the b=0 when SINR is higher than 18dB；When lower than 18db,
B=2.
In 5G network, due to using extensive mimo antenna, SINR 2-3 db usually high compared to 4G network.
Therefore the relationship in 5G network between CQI and SINR meets following formula:
SINR=a*CQI+b (2)
Wherein, a is gradient parameter, value 4；B is intercept parameter, the b=2 when SINR is higher than 18dB；When lower than 18db,
B=4.
The SINR value of each terminal is calculated according to above-mentioned formula 2.
S202, the ratio for determining first terminal in the multiple terminal.
Wherein, the first terminal is at least one terminal that SINR value is greater than the first threshold.
Specifically, passing through a large amount of reference experiment and data simulation, it can be deduced that such as draw a conclusion: when SINR value is greater than 20dB
When, the downstream rate of user is not changing substantially.Rate can not be promoted by promoting transmission power in this case, therefore
Can it is appropriate reduce base station transmission power balance handling capacity and transmission power to a suitable value.For example, selecting
SINR=20dB is the threshold value of adjustment, i.e., the described first threshold is 20dB.It can be by reducing to SINR's to more than 20dB
The transmission power of terminal reduces the transmission power of base station entirety.
Base station determines the SINR value of all terminals in coverage area, and the ratio of all terminals is accounted for according to wherein first terminal quantity
Example determines different adjustable strategies.
In the embodiment of the present application, three kinds of adjustment plans of ratio-dependent of all terminals are accounted for according to wherein first terminal quantity
Slightly.Integrated regulation strategy, partial adjustment strategy and not adjustable strategies.
If S203, the first terminal ratio shared in the multiple terminal meet the first preset condition, basis
First preset rules are adjusted the transmission power between the base station and each terminal.
Wherein, first preset condition is that the ratio is greater than the first preset ratio (such as 80%)；Described first is pre-
If rule is above-mentioned integrated regulation strategy.
Specifically, the first terminal determined in S202 ratio shared in the multiple terminal is greater than the first default ratio
Example (such as 80%), then judge in base station range at this time, and most terminal distribution distance SINR are better relatively close, and whole
Channel situation it is good (such case is mostly the multi-user concurrent business scenario of regional burst, for example, convention, movement meeting,
Etc. numbers burst concentrate scene).The situation is labeled as integrated regulation.Trigger integrated regulation strategy.That is: by the multiple end
(all terminals in the base station range) are held to arrange according to the sequence of SINR value from high to low.Successively by the base station and
Transmission power between each terminal is adjusted to default transmission power；If the hair between the base station and each terminal
It penetrates power and is adjusted to the default transmission power.
Illustratively, have in the base station range 10 terminals (be only for example and facilitate explanation, in practical applications,
Terminal quantity in base station range is far longer than 10).The SINR value of 10 terminals is as shown in the table:
Judge that the SINR value of terminal 1- terminal 8 in base station is all larger than 20, then the transmission power of terminal 1- terminal 8 is adjusted
It is whole, it is adjusted to corresponding transmission power when SINR value is 20.
In a kind of implementation of the application, base station can pass through following formula meters to the power of each terminal transmission
It calculates:
Wherein, PTX_aFor the total transmission power of base station, NRB_SFor the number of each UE resource block RB being assigned to, SINRui
For the SINR value of the user.
It is 200W or 100W that the total transmission power of the base station 5G, which is generally, at present.
After adjusting to the transmission power of terminal 1- terminal 8, the overall emitted power of base station is reduced.At this point, due to terminal 9
Smaller with the SINR value of terminal 10, the network communication quality that may result in terminal 9 and terminal 10 is affected, and improves at this time eventually
End 9 and the transmission power of terminal 10 (improve to SINR value be 20db when corresponding transmission power or SINR value be slightly less than 20db when
Corresponding transmission power), to improve the network communication quality of terminal 9 and terminal 10.Due to first terminal in base station range
Quantity account for 80% or more, so even if improving the transmission power of the remaining terminal less than 20%, the overall transmitted power of base station
Generally relatively still there is larger reduction originally.So this step can not only reduce the transmission power of base station, while can also be to base station
The terminal that original signal quality is poor in coverage area carries out tuning, improves the web experience of user.
Transmission power between the terminal of in a kind of implementation of this step or base station and part is adjustment
The extremely default transmission power, but the transmission power of the base station has been distributed to maximum value, then terminates the transmission power adjustment.
Base station overall transmitted power is not apparent from reduction at this time, but is remarkably improved the service quality of the terminal to SINR value less than 20.
If S204, the first terminal ratio shared in the multiple terminal meet the second preset condition, basis
Second preset rules are adjusted the transmission power between the base station and each terminal.
Wherein, second preset condition is that the first terminal proportion is pre- greater than second less than the first preset ratio
If ratio.Second preset rules are above-mentioned partial adjustment strategy.
Illustratively, first preset ratio is 80%, and the second preset ratio is 50%.
Specifically, the ratio ratio default less than first that the first terminal determined in S202 is shared in the multiple terminal
Example (such as 80%) is greater than the second preset ratio (such as 50%), then judges in base station range at this time compared with multiple terminals (first
Terminal) distribution distance SINR is better relatively close, and channel situation is good.But still have part terminal distribution distance SINR it is better farther out and
Channel quality is poor, at this time base station can not it is better to the distribution distance SINR in coverage area farther out and the poor entirety of channel quality
Carry out tuning.In this case, base station is only adjusted transmission power.The situation is labeled as partial adjustment at this time.Touching
Send out partial adjustment strategy.That is: first terminal in the multiple terminal is marked；By at least one described first terminal according to SINR value
Sequence arrangement from high to low；The transmission power between the base station and each terminal is successively adjusted to default transmitting function
Rate.
Illustratively, there are 10 terminals in the base station range.The SINR value of 10 terminals is as shown in the table:
| Terminal | SINR |
| 1 | 26 |
| 2 | 25 |
| 3 | 24 |
| 4 | 23 |
| 5 | 21 |
| 6 | 19 |
| 7 | 18 |
| 8 | 16 |
| 9 | 9 |
| 10 | 8 |
Judge that the SINR value of terminal 1- terminal 5 in base station is all larger than 20, then the transmission power of terminal 1- terminal 5 is adjusted
It is whole, it is adjusted to corresponding transmission power when SINR value is 20.Wherein, the calculation method of transmission power adjusted is calculated are as follows:
XXX.It does not adjust to other terminals.
In a kind of implementation of this step, second preset condition further includes that second terminal proportion is greater than the
Three preset ratios are less than the 4th preset ratio；Third preset ratio is 20%, and the 4th preset ratio is 50%.By pre- to second
If the further limiting of condition can specify base station can not the terminal to poor signal quality in coverage area carry out whole tuning, from
And it is adjusted just for base station transmitting power.
If S205, the first terminal ratio shared in the multiple terminal meet third preset condition, not right
Transmission power between the base station and each terminal is adjusted.
Wherein, the third preset condition is that the first terminal proportion is less than third preset ratio (20%)；Institute
Stating third preset rules is above-mentioned not adjustable strategies.
Specifically, the first terminal proportion determined in S202 is less than third preset ratio (20%).Then judge this
When base station range overwhelming majority terminal distribution distance SINR it is better farther out and channel quality is poor.At this point, even if to first
Terminal, which is adjusted, can not also obtain preferable adjustment effect, cannot be substantially reduced the transmission power of base station.Base station is whole to first
End is calculated the calculating pressure that will increase base station instead.At this point, necessity of modulated whole base station transmitting power.At this time by the situation
Labeled as not adjusting.Adjustable strategies, the holding existing power distribution strategies in base station do not carry out the transmission power of base station for triggering
Adjustment.
