It is many.
Further, it is more than or equal to default value when the first user connects the ratio between number and second user connection number
When, then the 3rd transmission power and the 4th transmission power are not adjusted.
Step 308：3rd transmission power is reduced into power difference, and the 4th transmission power is increased into power difference；
Alternatively, power difference is compared with minimum power threshold, if power difference is more than minimum power threshold,
The 3rd transmission power is then reduced into power difference, and the 4th transmission power is increased into power difference.
Further, if power difference is less than or equal to minimum power threshold, the 3rd transmission power and the 4th are sent out
Power is penetrated not adjust.
Step 309：Keep the 3rd transmission power and the 4th transmission power constant.
Further, after being adjusted to the 3rd transmission power and the 4th transmission power, network side equipment is to first
The cell-level parameter of cell is adjusted, and then adjusts the PDSCH transmission powers of first community, and the use included to first community
The corresponding user equipment in family sends SIB message, and the corresponding user equipment of user for including first community knows its downlink
Power is adjusted；And the cell-level parameter of second community is adjusted, and then adjust the PDSCH transmitting work(of second community
Rate, and the corresponding user equipment of user included to second community sends SIB message, the user for including second community is corresponding
User equipment knows that its down transmitting power is adjusted.
Wherein, due between the power of the PDSCH transmission powers of cell user equipment demodulating data corresponding with the user
In the presence of a biasing, when adjusting the PDSCH transmission power of cell, the transmission power of the PDSCH after adjustment is disappeared by SIB
Breath is sent to the corresponding user equipment of user that the cell includes, the corresponding user equipment adjustment solution of the user for including the cell
The power of adjusting data, and then make the corresponding user equipment of the user correctly demodulating data.
In embodiments of the present invention, for two cells after the vertical splittings of AAS, when the access of cell user compared with
