As shown in figure 1, the resource regulating method can include：

Step 101：At least one the first HUE in one group of femtocell user HUE is judged according to preparatory condition, it is described At least one the first HUE constitutes HUE first sets, determines the first resource block that all HUE in the HUE first sets take RB total quantity n1；

Judge whether the HUE in one group of HUE is the first HUE according to preparatory condition, and by determine at least one first HUE is combined into HUE first sets, and then determines the total quantity of the first RB that HUE takes in HUE first sets.

Wherein, the preparatory condition is used to determine HUE for when being disturbed HUE, the preparatory condition can be：HUE letter It is dry to make an uproar than less than Signal to Interference plus Noise Ratio threshold value；Or MUE reception jamming power is more than reception jamming power threshold on the RB of HUE occupancy Value.When the preparatory condition is used to determine HUE for interference HUE, the preparatory condition can be：Carried on the RB that HUE takes MUE Signal to Interference plus Noise Ratio is less than Signal to Interference plus Noise Ratio threshold value.

This step is also construed as：When judging that the HUE of at least one in HUE meets preparatory condition, HUE first sets are determined In HUE take the first RB total quantity n1；The HUE first sets include meeting all HUE of preparatory condition；It is described Preparatory condition is used to determine that HUE is the first HUE.

Step 102：Judge whether free time RB total quantity n2 is less than n1, when n2 is not less than n1, perform step 103；N2 is small When n1, step 104 is performed.

Step 103：N1 free time RB is selected from n2 free time RB, n1 free time RB of selection is distributed into HUE first HUE in set；

Step 104：N3 HUE, the RB sums m0 that the n3 HUE takes is selected to be not more than n2 from HUE first sets, M0 free time RB is selected from n2 free time RB, m0 free time RB of selection is distributed into the n3 HUE；From n1 the first RB Middle selection (n1-m0) individual first RB, by (n1-m0) of selection individual first RB distribute to described in HUE first sets n3 HUE it Outer HUE.

In resource regulating method shown in Fig. 1, when between the uplink communication interference HeNB sides between MUE and MeNB and HUE Uplink communication when, or, during downlink communication between downlink communication between HeNB sides and HUE interference MUE and MeNB, pass through The idle RB of HeNB sides realizes the scheduling of resource for the first HUE, solves the phase of HeNB sides in MeNB and i-Femtocell Mutual interference problem, improves QoS supportability of the HeNB sides to HUE, and improves QoS supportabilitys of the MeNB to MUE, so that Improve supportability of the HetNet networks to user QoS.

Step 201：Detect the Signal to Interference plus Noise Ratio SINR_hue of each HUE in all HUE in HeNB sides.

General, HeNB sides with a certain predetermined period, can periodically detect that the letter of each HUE in all HUE is dry and make an uproar Compare SINR_hue.The length of the predetermined period is not limited here.

Detect that all HUE Signal to Interference plus Noise Ratio SINR_hue can include in HeNB sides：

Detect the reception jamming power RIP of MUE on all RB in HeNB sides；Also, HeNB detects side itself receive each Individual HUE sends the signal power of signal；

HeNB lateral roots according to MUE on the corresponding signal powers of HUE, the affiliated RB of HUE reception jamming power RIP and receive noise Calculate Signal to Interference plus Noise Ratio SINR_hues of the HUE on its affiliated RB.

Step 202：HeNB sides judge whether each HUE Signal to Interference plus Noise Ratio SINR_hue is less than the first Signal to Interference plus Noise Ratio threshold value When SINR_hue_th, at least one HUE Signal to Interference plus Noise Ratio are less than the first Signal to Interference plus Noise Ratio threshold value, step 203 is performed；Otherwise, return Step 201 proceeds the detection of HUE Signal to Interference plus Noise Ratio.

In step 201~step 202 be dried according to HUE letter than be less than the first letter dry than threshold value judge by To the HUE of interference；And because when the same RB of MUE and HUE occupancy carries out data transmission, can just there is interference between MUE and HUE Problem, therefore, in actual applications, can also by judge MUE reception jamming power be more than receive jamming power threshold value come Judge that the MUE is interfered, and then be just interfered with the MUE HUE for taking same RB, accordingly, can also be judged by dry The HUE disturbed, likewise, in step 208~step 209 this method can also be used to judge the HUE being disturbed, does not go to live in the household of one's in-laws on getting married here State.

Step 203：HeNB sides determine the total quantity n1, the HUE that are disturbed RB that the HUE in HUE first sets takes It is less than the HUE of the first Signal to Interference plus Noise Ratio threshold value in first set comprising all Signal to Interference plus Noise Ratio.

Step 204：HeNB sides determine the total quantity n2 of free time RB in HeNB sides, judge whether n2 is less than n1, if n2 is not Less than n1, step 205 is performed；Otherwise, step 206 is performed.

Step 205：HeNB sides select n1 free time RB from n2 free time RB, and described n1 free time RB is distributed into HUE HUE in first set；Currently processed flow terminates.

Wherein, when selecting n1 free time RB from n2 free time RB, can arbitrarily it select at random, or it is pre- according to certain If rule selection, for example, n1 sky is selected according to channel gains of the HUE of HUE first sets on n2 free time RB from big to small Not busy RB etc., is not limited here.

Step 206：HeNB sides select n3 HUE from HUE first sets, and the RB sums m0 that the n3 HUE takes is not More than n2, m0 free time RB is selected from n2 free time RB, described m0 free time RB is distributed into the n3 HUE；

Step 207：HeNB sides from n1 be disturbed RB in selection n1-m0 be disturbed RB and distribute in HUE first sets HUE outside the n3 HUE；Also, indicate that the HUE outside the n3 HUE is disturbed on RB at the n1-m0 to use Maximum uplink transmission power carries out the transmission of data.

Wherein, wherein n3 minimum HUE of channel gain can be selected when selecting n3 HUE from HUE first sets.

From n1 be disturbed RB in selection n1-m0 be disturbed RB when can select to cause the HUE outside the n3 HUE The maximum n1-m0 RB of channel gain.

Here, HeNB sides indicate that the HUE outside the n3 HUE uses maximum up hair on the n1-m0 RB That send power progress data is transmitted as optional step, and the reason for performing the step is：Due to the HUE outside the n3 HUE It is dispensed on to be disturbed on RB and carries out data transmission, therefore, still can be interfered, indicates the HUE being disturbed using most Influence of the reduction interference that the transmission that big uplink transmission power carries out data can try one's best to data transfer, so as to ensure as far as possible The data transmission quality for the HUE being disturbed.
