- the base station receives the measured value of the serving cell and the measured value of the neighboring cell reported by the terminal in a preset period.

- the serving cell measurement value may be a serving cell RSRP (Reference Signal Receiving Power) measurement value
- the neighbor cell measurement value may be a neighboring cell RSRP measurement value.
- the measurement value of the serving cell and the neighboring cell measurement value may also be RSRQ (Reference Signal Receiving Quality) or signal to noise ratio.
- the terminal that reports the measurement value of the serving cell and the measurement value of the neighboring cell is a terminal designated by the base station, and is generally a terminal at the cell edge.
- the base station determines the interference measurement value according to the measured value of the serving cell and the measured value of the neighboring cell.
- the interference measurement value is 1/log (the serving cell RSRP measurement value - the neighboring area RSRP measurement value), and when the serving cell measurement value and the neighboring cell measurement value are the RSRQ or the SNR, the serving cell and the neighboring cell may also be used.
- the signal-to-noise ratio of the RSRQ or the serving cell and the neighboring cell determines the interference measurement value.
- the interference measurement value is used to indicate the degree of interference of the serving cell by the neighboring cell, and the greater the interference measurement value, the greater the interference of the neighboring cell to the serving cell.

- it is required to coordinate the transmission power of the adjacent cell on each RE, so that the transmission power of the neighboring cells on the same RE is staggered, and the process of coordinating the cell interference is more complicated than the embodiment of the present invention.
- the transmit power of the serving cell needs to be adjusted according to the interference measurement value, and the transmission power of two adjacent cells does not need to be coordinated, which simplifies the process of coordinating cell interference.
- step 203 the base station adjusts the transmit power of the serving cell according to the interference measurement value. Now it is step 2031 or step 2032.
- the base station When the interference measurement value is less than the first preset threshold, the base station gradually amplifies the transmit power of the serving cell by using a preset step size until the interference measurement value reaches a second preset threshold or the transmit power of the serving cell reaches a preset maximum power.
- the first preset threshold is less than or equal to the second preset threshold. It should be noted that the first preset threshold and the second preset threshold may be equal, but when the first preset threshold is equal to the second preset threshold, the ping-pong repeated adjustment is prone to occur, so generally setting the first preset threshold

- the measured cell measurement value and the neighbor cell measurement value reported by the terminal are still received in a preset period, and the interference measurement value is determined.
- the automatic adjustment process is terminated.
- the interference measurement value is larger, the interference of the neighboring cell to the serving cell is larger.
- the interference measurement value is smaller than the second preset threshold, the interference generated by the neighboring cell to the serving cell is small and can be accepted. If the interference measurement value is greater than the second preset threshold, if the transmission power of the base station is continuously increased, the signal of the terminal at the edge of the serving cell may be excessively interfered, so that the transmission power of the base station is stopped from increasing.
- the base station When the interference measurement value is greater than the third preset threshold, the base station gradually reduces the transmit power of the serving cell by using a preset step size until the interference measurement value is less than the fourth preset threshold or The base station reduces the accumulated value of the transmit power of the serving cell to a protection value.
- the third preset threshold is greater than or equal to the fourth preset threshold. It should be noted that the third preset threshold and the fourth preset threshold may be equal, but when the third preset threshold is equal to the fourth preset threshold, the ping-pong repeated adjustment is prone to occur, so generally setting the third preset threshold
- the interference measurement value interval between the fourth preset threshold and the third preset threshold is used as a buffer for adjusting the transmit power of the cell. The following describes an example in which the third preset threshold is greater than the fourth preset threshold.
- the base station needs to gradually reduce the transmit power of the serving cell by a preset step, as shown in FIG. 5. As shown, reducing the transmit power of the cell B can make the signal coverage of the cell B smaller, thereby reducing the interference between the cell A and the cell B.
- the base station When the base station starts to gradually reduce the transmit power of the serving cell in a preset step, the base station still receives the measured value of the serving cell and the measured value of the neighboring cell reported by the terminal in a preset period, thereby determining the interference measurement value, and the base station will serve the serving cell each time.
- the transmission power is reduced by one step, and the interference measurement value is compared with the second preset threshold. When the interference measurement value is less than the second preset threshold, the interference generated by the neighboring cell to the serving cell is within an acceptable range. Then, stop reducing the transmission power of the serving cell.
- the protection value is set to prevent the transmission power of the serving cell from being reduced by a large amount. Therefore, each time the base station reduces the transmission power of the serving cell by one step, it is determined whether the accumulated value of the transmission power of the serving cell has reached the protection value. When it is reached, the base station also stops reducing the transmit power of the serving cell.
- the second preset threshold in step 2031 and the fourth preset threshold in step 2032 may be equal.
- the base station receives the measured value of the serving cell reported by the terminal and the measured value of the neighboring cell in a preset period, and determines the interference measurement value according to the measured value of the serving cell and the measured value of the neighboring cell, when the interference measurement value is used.
- the base station When the threshold is smaller than the first preset threshold, the base station gradually amplifies the transmit power of the serving cell by using a preset step, until the interference measurement When the quantity reaches the second preset threshold or the transmit power of the serving cell reaches the preset maximum power, when the interference measurement value is greater than the third preset threshold, the base station gradually reduces the transmit power of the serving cell by using a preset step size until the interference measurement The value is less than the fourth preset threshold.
