Rather, use of the word "exemplary" or "such as" is intended to present concepts related in a concrete fashion.
In the description of the present application, the meaning of "a plurality" means two or more unless otherwise specified.
The power adjustment method provided in this embodiment may be applied to a communication network, which may be, for example, a 5G communication network, an LTE network, a Global System for Mobile communications (GSM), a Code Division Multiple Access (CDMA) System, a Time Division Multiple Access (TDMA) System, a Wideband Code Division Multiple Access (WCDMA) System, a Frequency Division Multiple Access (FDMA) System, an Orthogonal Frequency Division Multiple Access (OFDMA) System, a General Packet Radio Service (GPRS) System, and a next-generation Mobile communication System or other such communication systems, and the present embodiment is not limited thereto.
The power adjustment method provided by the embodiment of the application is applied to the communication system shown in fig. 1. The communication system 100 comprises a base station 101 and a plurality of terminals 102. The base station 101 and the terminal 102 transmit data therebetween by wireless signals.
The embodiment of the application provides a power adjustment method, which is applied to a communication system shown in fig. 1. The method may be performed by the base station described above. The base station may be an LTE base station, a 4G base station, a 5G base station, etc., and the following embodiments of the present application will be described in a belief that the base station is a 5G base station. As shown in fig. 2, the method includes S201-S205:
s201, obtaining SINR values of the plurality of terminals.
The SINR value is a ratio of the strength of the useful signal received by the terminal to the strength of the received interference signal (noise and interference). SINR is S/(I + N) RSRP/(RSSI-RSRP). Wherein S represents the received Power of the terminal, and may be generally represented by Reference Signal Receiving Power (RSRP); the Received Signal Strength Indication (RSSI) I + N is the sum of interference and noise, including non-serving cell, adjacent channel interference, and system internal thermal noise power.
Specifically, in the 5G network, the strength of the signal is described by using 2 SINRs, i.e., a reference Channel and a traffic Channel Quality Indicator (CQI) SINR. Since the CQI-SINR is directly related to demodulation of user data and has a great correlation with the user data rate, the corresponding relationship between CQI-SINR and power is mainly considered in the present application, and all SINRs mentioned in the following contents of the embodiments of the present application are CQI-SINR.
Since the 5G network has not been deployed formally, it is unclear what way to obtain the SINR value of the terminal in the future 5G commercial process. Therefore, in this step, two ways of acquiring the terminal SINR values are listed, which are only for convenience of better explanation of the scheme and should not be construed as limiting the way of acquiring the terminal SINR values. In practical applications, this step may be implemented in any manner known to those skilled in the art to obtain the SINR value of the terminal.
And in the first mode, the feedback SINR value of the terminal is directly obtained. Specifically, in a future 5G commercial network, the 5G terminal may have a function of directly reporting the SINR value. Therefore, the base station can acquire SINR values of respective terminals at fixed time intervals.
And the second mode is to acquire the SINR value through the CQI. Specifically, a Channel Quality Indication (CQI) value of each terminal is obtained; and calculating the SINR value of each terminal according to the CQI value of each terminal and a preset formula.
In the existing 4G network, the relationship between CQI and SINR satisfies the following formula:
SINR＝a*CQI+b (1)
wherein a is a gradient parameter and takes a value of 4; b is an intercept parameter, and b is 0 when the SINR is higher than 18 dB; below 18db, b is 2.
In 5G networks, the SINR is typically 2-3 db higher compared to 4G networks due to the massive MIMO antennas employed. Therefore, the relationship between CQI and SINR in a 5G network satisfies the following formula:
SINR＝a*CQI+b (2)
wherein a is a gradient parameter and takes a value of 4; b is an intercept parameter, and b is 2 when the SINR is higher than 18 dB; below 18db, b is 4.
The SINR value of each terminal is calculated according to the above formula 2.
S202, determining the proportion of the first terminal in the plurality of terminals.
The first terminal is at least one terminal with an SINR value larger than the first threshold.
Specifically, through a large number of reference experiments and data simulations, the following conclusions can be drawn: when the SINR value is greater than 20dB, the downlink rate of the user is basically not changed. In this case, the rate cannot be increased by increasing the transmission power, so that the transmission power of the base station can be appropriately decreased to an appropriate value to balance the throughput and the transmission power. For example, the threshold value is adjusted to be 20dB SINR, that is, the first threshold value is 20 dB. The overall transmit power of the base station can be reduced by reducing the transmit power to terminals with SINR greater than 20 dB.
And the base station determines SINR values of all terminals in the coverage area, and determines different adjustment strategies according to the proportion of the first terminal quantity in all the terminals.
In the embodiment of the application, three adjustment strategies are determined according to the proportion of the number of the first terminals in all the terminals. The overall adjustment strategy, the partial adjustment strategy and the non-adjustment strategy.
S203, if the proportion of the first terminal in the plurality of terminals meets a first preset condition, adjusting the transmitting power between the base station and each terminal according to a first preset rule.
Wherein the first preset condition is that the ratio is greater than a first preset ratio (e.g., 80%); the first preset rule is the overall adjustment strategy.
Specifically, if the proportion of the first terminal in the plurality of terminals determined in S202 is greater than a first preset proportion (e.g., 80%), it is determined that most of the terminals are closer to the SINR in the coverage area of the base station and the overall channel condition is good (this situation is mostly a regional burst multi-user concurrent service scenario, such as a large conference, a sports meeting, and a scenario in which the number of bursts is concentrated). This case is marked as global adjustment. Triggering an overall adjustment strategy. Namely: and arranging the plurality of terminals (all terminals in the coverage area of the base station) according to the sequence of SINR values from high to low. Adjusting the transmitting power between the base station and each terminal to be preset transmitting power in sequence; and if the transmitting power between the base station and each terminal is adjusted to the preset transmitting power.
Illustratively, there are 10 terminals in the coverage area of the base station (for example, the number of terminals in the coverage area of the base station is far greater than 10 in practical application). The SINR values for the 10 terminals are shown in the following table:
and if the SINR values of the terminals 1 to 8 in the base station are all larger than 20, adjusting the transmitting power of the terminals 1 to 8 to the corresponding transmitting power when the SINR value is 20.
In one implementation of the present application, the power transmitted by the base station to each terminal may be calculated by the following formula:
wherein, PTX_aIs the total transmission power of the base station, NRB_SNumber of resource blocks RB allocated to each UE, SINRuiThe SINR value for that user.
The total transmission power of the current 5G base station is typically 200W or 100W.
After the transmission power of the terminals 1-8 is adjusted, the overall transmission power of the base station is reduced. At this time, since the SINR values of the terminal 9 and the terminal 10 are small, the network communication quality of the terminal 9 and the terminal 10 may be affected, and at this time, the transmission power of the terminal 9 and the terminal 10 is increased (to the transmission power corresponding to the SINR value of 20db, or to the transmission power corresponding to the SINR value slightly lower than 20 db) to improve the network communication quality of the terminal 9 and the terminal 10. Since the number of the first terminals in the coverage area of the base station accounts for more than 80%, even if the transmission power of the remaining terminals less than 20% is increased, the overall transmission power of the base station is generally greatly reduced compared with the original transmission power. Therefore, the step not only can reduce the transmitting power of the base station, but also can optimize the original terminal with poor signal quality in the coverage area of the base station, and improve the network experience of users.
In an implementation manner of this step, or if the transmission power between the base station and a part of the terminals is adjusted to the preset transmission power, but the transmission power of the base station is allocated to the maximum value, the transmission power adjustment is ended. At this time, the total transmission power of the base station is not obviously reduced, but the service quality of the terminal with the SINR value less than 20 can be obviously improved.
And S204, if the proportion of the first terminal in the plurality of terminals meets a second preset condition, adjusting the transmitting power between the base station and each terminal according to a second preset rule.
The second preset condition is that the proportion of the first terminal is smaller than the first preset proportion and larger than the second preset proportion. The second preset rule is the partial adjustment strategy.
Illustratively, the first predetermined proportion is 80% and the second predetermined proportion is 50%.
Specifically, if the ratio of the first terminal in the plurality of terminals determined in S202 is smaller than a first preset ratio (e.g., 80%) and larger than a second preset ratio (e.g., 50%), it is determined that the distribution distance of more terminals (first terminals) within the coverage area of the base station is closer to the SINR and the channel condition is good. However, some terminals are far from the SINR good point and the channel quality is poor, and at this time, the base station cannot adjust the distribution distance within the coverage range, which is far from the SINR good point and the channel quality is poor. In this case, the base station only adjusts the transmit power. This case is marked as partial adjustment at this point. Triggering a partial adjustment strategy. Namely: tagging a first terminal of the plurality of terminals; arranging at least one first terminal in the order of SINR value from high to low; and adjusting the transmitting power between the base station and each terminal to be preset transmitting power in sequence.
Illustratively, there are 10 terminals in the coverage area of the base station. The SINR values for the 10 terminals are shown in the following table:
| terminal device | SINR |
| 1 | 26 |
| 2 | 25 |
| 3 | 24 |
| 4 | 23 |
| 5 | 21 |
| 6 | 19 |
| 7 | 18 |
| 8 | 16 |
| 9 | 9 |
| 10 | 8 |
And if the SINR values of the terminals 1 to 5 in the base station are all larger than 20, adjusting the transmitting power of the terminals 1 to 5 to the corresponding transmitting power when the SINR value is 20. The calculation method for calculating the adjusted transmitting power comprises the following steps: XXX. No adjustment is made to other terminals.
In an implementation manner of this step, the second preset condition further includes that the proportion of the second terminal is greater than a third preset proportion and less than a fourth preset proportion; the third preset proportion is 20%, and the fourth preset proportion is 50%. The second preset condition is further limited, so that the base station can not perform overall tuning on the terminal with poor signal quality in the coverage range, and the base station transmitting power is adjusted only.
S205, if the ratio of the first terminal in the plurality of terminals satisfies a third preset condition, not adjusting the transmission power between the base station and each of the terminals.
Wherein the third preset condition is that the proportion of the first terminal is less than a third preset proportion (20%); the third preset rule is the non-adjustment strategy.
Specifically, the proportion of the first terminal determined in S202 is smaller than the third preset proportion (20%). Then, the distribution distance of most terminals in the coverage area of the base station is far from the good point of the SINR and the channel quality is poor. In this case, even if the first terminal is adjusted, a good adjustment effect cannot be obtained, and the transmission power of the base station cannot be reduced significantly. The base station performing the calculation for the first terminal may increase the calculation pressure of the base station instead. At this time, it is necessary to adjust the transmission power of the base station. This case is marked as not adjusted at this point. And triggering a non-adjustment strategy, keeping the existing power distribution strategy of the base station, and not adjusting the transmitting power of the base station.
The power adjustment method provided by the embodiment of the application determines a first cell and at least one second cell; the first cell is a cell which needs to be subjected to power adjustment in the communication network; the second cell is a cell within the coverage of the first cell in the communication network.
