if the first channel quality indicator value is less than or equal to the second threshold value, calculating a second channel quality indicator value for the second at least one resource set, the second channel quality indicator value determined based on at least the interference floor for the second at least one resource set; and

if the second channel quality indicator value exceeds a third threshold value, transmitting the preferred radio resource indication identifying the preferred radio resource set as the second at least one resource set and transmitting a transmit power limit change indication requesting the one or more interfering base stations to adjust a transmission power level associated with at least an identified radio resource subset of the second at least one resource set.

12. The method of claim 1 , wherein the preferred radio resource set for the serving base station may be different from the preferred radio resource set for at least one of the one or more interfering base stations.

13. The method of claim 1 , wherein the preferred radio resource indication is encoded prior to being transmitted to at least the serving base station.

14. The method of claim 1 , wherein the preferred radio resource indication is transmitted with a channel quality indication report.

15. The method of claim 1 , wherein the interference is received from one or more interfering base stations and one or more devices different from base stations.
