Claim of US Patent No. 9,775,056

1. A method for performing interference control, comprising:
determining, by a network side device, a traffic load parameter value of each cell and a measurement parameter value between
base stations which serve for any two cells, the measurement parameter value between the base stations is one or more of the
following parameter values: a path loss value, a coupling loss value or an interference power value;

for the two cells, determining, by the network side device, an interference control threshold value according to the traffic
load parameter values of the two cells, comparing the measurement parameter value determined with the interference control
threshold value and dividing the two cells into clusters according to the comparison result; and

performing, by the network side device, interference control according to clusters after dividing;
wherein the performing, by the network side device, interference control according to the clusters after dividing comprises:
the network side device using the same uplink and downlink configuration for the cells in the same cluster, wherein the uplink
and downlink configuration is an allocation pattern of uplink and downlink sub-frames in a radio frame; and

the network side device using same or different uplink and downlink configurations for the cells in the different clusters.
