Abstract

An aggressor base station (22-1) herein performs downlink interference coordination with one or more victim base stations (22-2, 22-3)in a radio communication network (10). Such coordination is performed for each of one or more iterations. For any given iteration, the aggressor (22-1) sends a message (28-2) to a victim (22-2) that indicates, for each of one or more downlink resources (26), whether the aggressor (22-1) promises to protect that resource (26) from interference by not transmitting on the resource (26) with a transmit power above a threshold (T¾). The victim (22-2) schedules downlink transmissions to one or more user equipments (16) on resources (26) that, according to the message (28-2), are protected from interference. Based on monitoring for interference to those transmissions, though, the vietim (22-2) generates and sends to the aggressor (22-1) feedback (30-2) that generally requests an increase or decrease of the threshold (TH 2) . From evaluation of this feedback (30-2), the aggressor (22-1) determines a new threshold (TH2) on which promises are to be based in a message (28-2) to the victim (22-2) in a subsequent iteration.
