In above-mentioned three set, the quantity of the R-T unit that comprises in the set sorts from more to less and is: set one, set two, set three; Then,
At set one, in the average weighted scheme, the frequency of integrated interference value minimum is ARFCN1, then frequency ARFCN1 is distributed to carrier wave C0;
At set two, in the average weighted scheme, the frequency of integrated interference value minimum is ARFCN4, then frequency ARFCN4 is distributed to carrier wave C1;
At set three, the frequency of R-T unit 2 minimums is followed successively by ARFCN1, ARFCN4, ARFCN3, ARFCN2, ARFCN0 and ARFCN5, because frequency ARFCN1 has been configured to carrier wave C0, frequency ARFCN4 and has been configured to carrier wave C1, then, successively frequency ARFCN3 and ARFCN2 are disposed to carrier wave C2 and carrier wave C3;
And the frequency information that distributes sent to each R-T unit.
Scene four
In this scene, comprise three R-T units: R-T unit 0, R-T unit 1 and R-T unit 2, predetermined list of frequency comprises six frequencies altogether, be ARFCN0, ARFCN1, ARFCN2 ..., ARFCN5}.
R-T unit 0,1,2 covers three different zones respectively, R-T unit 0,1 and 2 bearing carrier wave C0, R-T unit 0 and 1 bearing carrier wave C1, R-T unit 2 bearing carrier wave C2 and C3, then, three R-T units need adopt an identical frequency to come bearing carrier wave C0, and R-T unit 0 and 1 needs to adopt an identical frequency to come bearing carrier wave C1, and R-T unit 2 needs to adopt two different frequencies to come bearing carrier wave C2 and carrier wave C3 respectively.
And, space length between the R-T unit 0,1,2 is all greater than predetermined space isolation distance, that is to say, when different transceiver modules carry different carrier, its working frequency points can be configured to same frequency, be configured to the different transceiver modules of same frequency when the carrying different carrier, avoid disturbing when guaranteeing that by the space isolation distance between different transceiver modules common frequency carries different carrier.
The processing procedure of determining frequency comprises:
Step 1 is identical to step 3 with step 1 in the above-mentioned scene three to the handling principle of step 3, phase region other be, in this scene, (first set comprises R-T unit 0,1 and 2 at three set, second set comprises R-T unit 0 and 1, the 3rd set comprises R-T unit 2), do not distinguish the sequencing of set, be each set dividing frequency;
At set one, in the average weighted scheme, the frequency of integrated interference value minimum is ARFCN1, then frequency ARFCN1 is distributed to carrier wave C0;
At set two, because ARFCN1 disposes to C0, and each R-T unit all need carry C0, and therefore, other carrier waves can not dispose ARFCN1 again and carry in three R-T units.In the average weighted scheme, R-T unit 0,1 is got rid of outside the frequency ARFCN1, and the frequency of integrated interference value minimum is ARFCN4, then frequency ARFCN4 is distributed to carrier wave C1;
At set three, similarly, because ARFCN1 disposes to C0, and each R-T unit all need carry C0, therefore, in three R-T units other carrier waves again configuration frequency ARFCN1 carry.But because the space isolation distance between the R-T unit 0,1 and 2 is enough, so can consider that also configuration is to set three for configuration the ARFCN4 of set two according to the concrete disturbed condition of eating dishes without rice or wine.R-T unit 2 is got rid of outside the frequency ARFCN1, eat dishes without rice or wine to disturb minimum frequency to be followed successively by ARFCN4, ARFCN3, ARFCN2, ARFCN0 and ARFCN5, therefore ARFCN4 is disposed to R-T unit 2 bearing carrier wave C2, ARFCN3 disposes to R-T unit 2 bearing carrier wave C3.
From above-mentioned configuration as can be seen, set two, i.e. R-T unit 0,1, with ARFCN4 bearing carrier wave C1, set three, namely R-T unit 2, with ARFCN4 bearing carrier wave C2, from frequency configuration as can be seen, carrier wave C1 and C2 are carried by same frequency ARFCN4, because the space length between the R-T unit 0,1,2 is all greater than predetermined space isolation distance, therefore, even if carry different carrier wave C1 and C2 with same frequency ARFCN4, can not cause yet and eat dishes without rice or wine to disturb; By adopting this method configuration effort frequency, because the alternative frequency number of each R-T unit increased, therefore, find clean working frequency points easilier.
And the frequency information that distributes sent to each R-T unit.
In sum, the base station obtains each R-T unit interference value of eating dishes without rice or wine on each frequency in predetermined list of frequency, the R-T unit of carrying same carrier wave is divided in the set, the integrated interference value of this frequency during the weighted sum of the interference value of eating dishes without rice or wine of R-T unit on frequency in the set is defined as respectively gathering, give each R-T unit in the set with the frequency configuration of integrated interference value minimum in the set, can take all factors into consideration each frequency at the disturbed condition of eating dishes without rice or wine at each R-T unit place, guarantee that the integrated interference value of institute's selected frequency at each common carrier R-T unit place minimizes, guarantee the purpose of base station working frequency minimum interference effectively, improve whole covering quality.
