Distance it is identical it is then any select a base station as apart from nearest base station, and apart from nearest base station can with set transmitting function
The base station of rate is identical)；By taking emulation as an example, there are two the base stations that priority is 1, randomly select one, it is assumed that under selection base station 2 is
One highest priority base station, then base station 10 is the nearest base station of next distance.

Transmission power: PD=min { IC+LCD, IE+LCD/2, IC+LAD, IE+LAD/2, IC+LBD, IE+LBD/2, PMAX}。
It can be 36.39dBm with the transmission power of calculation base station 2, the transmission power of base station 10 is by taking emulation as an example
36.39dBm。
(9) judge whether the transmission power apart from next nearest base station is less than the minimum emissive power of the base station, if it is
Then close the nearest base station of next distance, again the nearest base station in selected distance lower highest priority base station as next distance most

It is set as the value being calculated, executes step (10)；
(10) step (6) are jumped to, until the transmission power setting of all base stations finishes；
Here calculating needs to consider not interfere all base stations for having been allocated for power, until all base stations
Calculating finishes.The sequencing for calculating power is determined by the setting of priority in this way, solving multi-parameter can not obtain most
Excellent the problem of solving or can not restraining, meet the real-time of power calculation.
The transmission power that finally can be calculated all base stations is as follows, and wherein base station 6 apart from base station 5 because too closely, calculating
Power be less than minimum power 30dBm, therefore close base station 6.
