Use number of resources or power measurement values divided by the path loss of this interference adjacent area to described resource user to be allocated each frequency descending time slot of selected interference adjacent area, obtain the interference value that described resource user to be allocated receives described interference adjacent area in the corresponding time slot of corresponding frequency;
The interference value of the whole interference adjacent areas received on each time slot by described resource user to be allocated adds up respectively, obtains the total interference value in interference adjacent area of each time slot;
According to the total interference value in interference adjacent area of described each time slot, obtain the descending interference value of each frequency of described Serving cell;
Wherein, described in described interference assessment module estimation, the method for interference user to the interference of the corresponding time slot of the corresponding frequency of described Serving cell comprises:
Use number of resources or power measurement values divided by the path loss of this community, interference user place to described resource user to be allocated at descending time slot the interference user of selected interference adjacent area, obtain the interference value that described resource user to be allocated receives described interference user in the corresponding time slot of corresponding frequency;
The interference value of the whole interference users received on each time slot by described resource user to be allocated adds up respectively, obtains the total interference value of interference user of each time slot;
According to the total interference value of interference user of described each time slot, obtain the descending interference value of each frequency of described Serving cell.
9. device as claimed in claim 8, is characterized in that, the method that described interference assessment module chooses interference adjacent area comprises:
In the neighbor cell of this Serving cell, resource user place to be allocated described resource user measurement to be allocated obtained, the received signal code power of Primary Common Control Physical Channel is greater than the neighbor cell of configured absolute field strength thresholding as described interference adjacent area; Or
With the neighbor cell of the difference of the received signal code power of the Primary Common Control Physical Channel of this Serving cell lower than configured relative field strength thresholding in the neighbor cell of this Serving cell, resource user place to be allocated that described resource user measurement to be allocated is obtained, as described interference adjacent area.
